ObjectiveTo explore the correlation between the Barthel index score and other factors with the preoperative occurrence of deep vein thrombosis (DVT) in patients undergoing total hip arthroplasty (THA) revision surgery. MethodsA retrospective analysis was conducted on clinical data from 122 patients who met the inclusion criteria and underwent THA revision surgery between April 2017 and November 2020. Among them, 61 were male and 61 were female, with an age range of 32-85 years (mean, 65.3 years). The reasons for revision included prosthetic joint infection in 7 cases, periprosthetic fracture in 4 cases, prosthetic dislocation in 6 cases, and aseptic loosening in 105 cases. The Barthel index score was 76.4±17.7, with 10 cases classified as level 1, 57 as level 2, 37 as level 3, and 18 as level 4. Univariate analysis was performed on variables such as age, gender, body mass index, Barthel index score, preoperative D-dimer positivity, history of diabetes, hypertension, cancer, cerebral infarction, smoking, and thrombosis in patients with and without preoperative DVT. Furthermore, logistic regression was used to identify risk factors for preoperative DVT in THA revision surgery. The incidence of preoperative DVT was compared among different Barthel index score groups. ResultsPreoperative DVT was detected in 11 patients (9.02%), all of whom had intermuscular venous thrombosis. Among them, 1 had prosthetic joint infection, 1 had periprosthetic fracture, 1 had prosthetic dislocation, and 8 had aseptic loosening. Univariate analysis showed significant differences between the two groups in terms of age, gender, and Barthel index score (P<0.05). logistic regression further revealed that female, age ≥70 years, and Barthel index score<60 were independent risk factors for preoperative DVT in patients undergoing THA revision surgery (P<0.05). The incidence of preoperative DVT in patients with Barthel index scores of levels 1, 2, 3, and 4 were 0 case (0%), 2 cases (3.5%), 3 cases (8.1%), and 6 cases (33.3%), respectively. A significant correlation was found between Barthel index score classification and the incidence of preoperative DVT in patients undergoing THA revision surgery (χ2=10.843, P=0.001). ConclusionIn patients undergoing THA revision surgery, older age, female, and lower Barthel index scores are associated with higher preoperative DVT incidence. For patients with low preoperative Barthel index scores, preoperative thrombosis screening should be emphasized.
ObjectiveTo discuss the implantation and conversion technology of convertible inferior vena cava filter and the experience of management.MethodsThe clinical data of 115 patients with convertible inferior vena cava filter implantation admitted to our vascular surgery center from January 2018 to December 2018 was retrospectively analyzed.ResultsAmong the 115 patients with convertible inferior vena cava filter implantation, 74 were males and 41 were females. The ages ranged from 22 to 87 years, with median age 54 years. The successful rate of filter implantation was 100% without any surgical related complications. After implantation surgery, patients were followed up from 4 to 455 days with a median of 90 days and the recurrence rate of adverse events was 7.8% (9/115). The recurrence time were 16 to 104 days after conversion, with a median of 42 days. Twenty-three patients (20.0%) received filter conversion, one of them failed and all the others succeeded. The technical successful rate was 95.7% (22/23). The conversion operative time was 22.8 to 51.4 min, with median time 27.4 min. The intervals between implantation and conversion were from 4 to 455 days, with median time 159 days. Accessory techniques were used in 20 of 22 successful filter conversions and the application rate of accessory technique was 90.9%. The patients were followed-up from 30 to 180 days after conversion with a median time of 90 days and no adverse event was reported.ConclusionConvertible inferior vena cava filter is a significant choice for patients application of inferior vena cava filter due to its high safety of conversion surgery, technical success rate and possibility of conversion after long-term indwelling.
Objective To investigate the short-term result of catheter directed thrombolysis (CDT) in treatment of acute deep venous thrombosis (DVT) in lower extremity. Methods A total of 289 cases of acute DVT in lower extremity who got treatment in Nanjing Drum Tower Hospital Group Suqian City People’s Hospital and Xuzhou Central Hospital from March 2013 to December 2014 were enrolled prospectively, and of them, 125 cases of system thrombolysis (ST) group underwent ST, 164 cases of CDT group underwent inferior vena cava filter placement (IVCF)+CDT. Clinical effect was compared between the 2 groups. Results Clinical symptoms of all cases were obviously relieved, and limb swelling was significantly reduced. Of the CDT group, 73 cases presented iliac vein compression syndrome (IVCS), and 43 cases of them underwent the percutaneous transluminal angioplasty and stent implantation. In CDT group, there was 1 case complicated by catheter displacement, 10 cases suffered from puncture site ecchymosis, 3 cases suffered from hematuria. In ST group, there was 1 case suffered from pulmonary embolism (PE), 14 cases suffered from bleeding gums, 22 cases suffered from hematuria, 3 cases suffered from skin and mucosa petechia, and 2 cases suffered from melena (didn’t need transfusion). The morbidity of ST group was higher than that of CDT group (P=0.002). There were 18 cases suffered from recurrence in ST group, 15 cases suffered from recurrence in CDT group, but there was no significant difference in the recurrence rate between the 2 groups (P=0.786). In addition, the dosage of urokinase, thrombolysis time, blood vessel patency score, thigh circumference after treatment, and calf circumference after treatment in ST group were all higher than those of CDT group (P<0.050), but the Villalta score in ST group was lower than that of CDT group (P<0.001). There was no significant difference in hospital stay (P=0.383). Conclusion For acute DVT in lower extremity, CDT has a superior short-term outcome with safety and feasibility.
Objective To explore the efficiency of artificial intelligence algorithm model using preoperative blood indexes on the prediction of deep vein thrombosis (DVT) in patients with lower limb fracture before operation. Methods Patients with lower limb fracture treated in the Department of Orthopedics of Deyang People’s Hospital between January 2018 and December 2022 were retrospectively selected. Their basic and clinical data such as age, gender, height and weight, and laboratory examination indicators at admission were collected, then the neutrophi to lymphocyte ratio (NLR), monocyte to lymphocyte ratio (MLR), and platelet to lymphocyte ratio (PLR) were calculated. According to color Doppler ultrasound indication of DVT in lower extremities at admission, the patients were divided into DVT group and non-DVT group. After data preprocessing, grey relational analysis (GRA) was used to screen the combination model of important predictive features of DVT, and BP neural network prediction model was established using the selected features. Finally, the accuracy of BP neural network prediction model was evaluated, and was compared with those of different models in clinical prediction of DVT. Results A total of 4033 patients with lower limb fracture were enrolled, including 3127 cases in the DVT group and 906 cases in the non-DVT group. GRA selected seven important predictive features: absolute lymphocyte value, NLR, MLR, PLR, plasma D-dimer, direct bilirubin, and total bilirubin. The accuracies of logistic regression analysis, random forest, decision tree, BP neural network and GRA-BP neural network combination model were 74%, 76%, 75%, 84% and 87%, respectively. The GRA-BP neural network combination model had the highest accuracy. Conclusion The GRA-BP neural network selected in this paper has the highest accuracy in preoperative DVT risk prediction in patients with lower limb fracture, which can provide a reference for the formulation of DVT prevention strategies.
ObjectiveTo compare the predictive value of six thrombotic risk assessment scales, including Autar, Wells, Padua, Caprini, Khorana, and COMPASS-CAT, for the deep venous thrombosis (DVT) of lower extremity in patients with gastrointestinal tumors. MethodsThe patients with gastrointestinal tumors who received surgical treatment in the General Surgery Department of Lanzhou University Second Hospital from March 2023 to October 2023 were collected. The risk of DVT on day 3 after surgery for the patient with gastrointestinal tumors was prospectively evaluated using the Autar, Wells, Padua, Caprini, Khorana, and COMPASS-CAT assessment scales. And the DVT was detected by ultrasound examination. The pionts of six thrombotic risk assessment scales were compared between the patient with DVT and without DVT based on the ultrasound examination results. The predictive value of the six thrombotic risk assessment scales for the lower extremity DVT in the patients with gastrointestinal tumors was evaluated by the area under receiver operating characteristic curve (AUC). ResultsA total of 108 patients who met the criteria, including 71 males and 37 females, were enrolled, age ranged from 18 to 85 years old, (58.3±11.2) years old. Fourty-two cases (38.9%) of DVT occurred. The age of patients with DVT was older than that of patients without DVT (P<0.05), but there were no statistical differences in the gender, body mass index, tumor location, comorbidities, and so on (P>0.05). The points of Autar, Padua, and Caprini in the patients with DVT were higher than those in the patients without DVT (P<0.05), while there were no statistical differences in the points of Wells, Khorana, and COMPASS-CAT between the two (P>0.05). The AUC for differentiating the occurrence of DVT in the patients with gastrointestinal tumors using the Autar, Wells, Padua, Caprini, Khorana, and COMPASS-CAT assessment scales were 0.907, 0.548, 0.636, 0.627, 0.589, and 0.535, respectively; The sensitivities were 97.6%, 14.3%, 52.4%, 83.3%, 47.6%, and 21.4%; The specificities were 2.4%, 85.7%, 47.6%, 16.7%, 52.4%, and 78.6%, respectively. ConclusionAccording to the abilities of Autar, Wells, Padua, Caprini, Khorana, and COMPASS-CAT to distinguish the occurrence of DVT in patients with gastrointestinal tumors after surgery, only the Autar evaluation scale is found to be more effective, while the other five evaluation scales are generally able to distinguish the occurrence of DVT.
Objective To explore the impact of anemia on the incidence of perioperative lower limb deep vein thrombosis (DVT) in patients undergoing total hip arthroplasty (THA). Methods A retrospective analysis was conducted on clinical data of 1 916 non-fracture patients who underwent THA between September 2015 and December 2021, meeting the selection criteria. Among them, there were 811 male and 1 105 female patients, aged between 18 and 94 years with an average of 59.2 years. Among the patients, 213 were diagnosed with anemia, while 1 703 were not. Preoperative DVT was observed in 55 patients, while 1 861 patients did not have DVT preoperatively (of which 75 patients developed new-onset DVT postoperatively). Univariate analysis was performed on variables including age, gender, body mass index (BMI), diabetes, hypertension, history of tumors, history of thrombosis, history of smoking, revision surgery, preoperative D-dimer positivity (≥0.5 mg/L), presence of anemia, operation time, intraoperative blood loss, transfusion requirement, and pre- and post-operative levels of red blood cells, hemoglobin, hematocrit, and platelets. Furthermore, logistic regression was utilized for multivariate analysis to identify risk factors associated with DVT formation. Results Univariate analysis showed that age, gender, hypertension, revision surgery, preoperative levels of red blood cells, preoperative hemoglobin, preoperative D-dimer positivity, and anemia were influencing factors for preoperative DVT (P<0.05). Further logistic regression analysis indicated that age (>60 years old), female, preoperative D-dimer positivity, and anemia were risk factors for preoperative DVT (P<0.05). Univariate analysis also revealed that age, female, revision surgery, preoperative D-dimer positivity, anemia, transfusion requirement, postoperative level of red blood cells, and postoperative hemoglobin level were influencing factors for postoperative new-onset DVT (P<0.05). Further logistic regression analysis indicated that age (>60 years old), female, and revision surgery were risk factors for postoperative new-onset DVT (P<0.05). Conclusion The incidence of anemia is higher among patients with preoperative DVT for THA, and anemia is an independent risk factor for preoperative DVT occurrence in THA. While anemia may not be an independent risk factor for THA postoperative new-onset DVT, the incidence of anemia is higher among patients with postoperative new-onset DVT.
ObjectiveTo investigate the effect of different use time of intermittent pneumatic compression (IPC) on the incidence of deep vein thrombosis (DVT) of lower extremities after arthroplasty.MethodsBetween October 2018 and February 2019, 94 patients who planned to undergo unilateral total hip or knee arthroplsty and met the selection criteria were randomly divided into a control group (47 cases) and a trial group (47 cases). There was no significant difference in gender, age, surgical site, and surgical reason between the two groups (P>0.05). After returning to the ward, all patients were treated with IPC. And the IPC was used until 9:00 pm on the day after operation in the trial group and until 8:00 am the next day after operation in the control group. The levels of hemoglobin, platelet count, D-dimer, hospital stay, treatment costs, patients’ satisfaction with IPC, the parameters of thromboelastrography [kinetics (K value), freezing angle (α angle), reaction time (R value), maximum amplitude (MA value)], visual analogue scale (VAS) score, circumference difference of calf before and after operation, Pittsburgh sleep assessment score, and the incidence of DVT of lower limbs were recorded and compared between the two groups.ResultsThe K value and D-dimer before operation were significant different between the two groups (P<0.05). There was no significant difference in pre- and post-operative hemoglobin, platelet count, and the other parameters of thromboelastography between the two groups (P>0.05). There was no significant difference in pre- and post-operative VAS scores and post-operative circumference difference of calf between the two groups (P>0.05). The sleep assessment score of the trial group at 1 day after operation was significant lower than that of the control group (t=2.107, P=0.038). There was no significant difference in the hospital stay and treatment costs between the two groups (P>0.05). There was 1 case (2.1%) of DVT, 3 cases (6.4%) of intermuscular venous thrombosis, and 1 case (2.1%) of infection in the trial group, and 2 cases (4.3%), 4 cases (8.5%), and 0 (0) in the control group. The differences were not significant (P>0.05). After the completion of postoperative IPC treatment, the satisfaction rates of using IPC were 89.4%(42/47) in the trial group and 70.2% (33/47) in the control group, and the difference was not significant (χ2=0.097, P=0.104).ConclusionIPC using for a short period of time after arthroplasty do not increase the degrees of the pain and the swelling of calf; it can effectively prevent DVT of the lower extremity, improve the quality of sleep in patients, and is good for the limbs rehabilitation.
With the widespread promotion and application of the Enhanced Recovery After Surgery (ERAS) concept in the surgical fields, the implementation of the ERAS concept in the treatment of lower extremity deep venous thrombosis (DVT) was explored in the vascular surgery. The “Six-Step” comprehensive treatment protocol and the establishment of the ERAS system for lower extremity DVT developed by the Department of Vascular Surgery at the First Affiliated Hospital of Chongqing Medical University were elaborated. The protocol includes steps such as filter placement, thrombus clearance, relief of venous outflow obstruction, dissolution of residual thrombus, filter retrieval, and standardized post-discharge anticoagulation management, along with their respective advantages. Additionally, the training and dissemination efforts undertaken to promote the “Six-Step” comprehensive treatment protocol were described. A comparison was made between ERAS and traditional recovery surgery, highlighting the comprehensive clinical benefits of the former. The aim is to promote the standardized implementation of the ERAS system in lower extremity DVT treatment and to bring greater benefits to patients.
ObjectiveTo evaluate the safety and mid-to-long term outcomes of catheter-directed thrombolysis (CDT) in combination with percutaneous mechanical thrombectomy (PMT) followed by stent placement treatment for acute proximal deep vein thrombosis (DVT) complicated by iliac vein compression syndrome (IVCS), and to identify risk factors relevent to primary stent restenosis. MethodsA retrospective study was conducted. The patients diagnosed with acute proximal DVT and concurrent IVCS who underwent CDT in combination with PMT followed by stent placement at the First Affiliated Hospital of Chongqing Medical University from January 2018 to December 2021 were included. The demographics, clinical history, and procedural data were collected. The postoperative follow-up using color Doppler ultrasound were scheduled at 3, 6, and 12 months, and annually thereafter. The primary and secondary stent patency rates were evaluated. The univariate and multivariate Cox proportional hazards regression models were employed to assess risk factors for primary stent restenosis. ResultsA total of 188 patients who met the inclusion and exclusion criteria were enrolled, underwent CDT combined with PMT and stent implantation, and completed follow-up. During the follow-up, the restenosis occurred in 26 patients. The cumulative primary patency rates at 3, 6, 12, 24, 36, and 48 months after surgery were 100%, 98.9%, 92.5%, 88.3%, 86.7%, and 86.2%, respectively. The multivariate Cox proportional hazards regression analysis confirmed that a history of previous DVT [HR (95%CI)=4.21 (1.73, 10.28), P=0.002], implantation of two or more stents [HR (95%CI)=11.85 (1.66, 84.63), P=0.014], stent crossing the inguinal ligament [HR (95%CI)=9.92 (1.87, 52.78), P=0.007], and stent length [HR (95%CI)=0.98 (0.97, 0.99), P=0.003] were the affecting factors for primary restenosis. ConclusionsThe findings of this study suggest that CDT combined with PMT and stent implantation is a safe and effective strategy for treating acute proximal DVT complicated by IVCS. Close attention should be paid to the occurrence of restenosis in patients with two or more stents, stent crossing the inguinal ligament, and a history of previous DVT.
ObjectiveTo compare the effect of catheter-directed thrombolysis (CDT) combined with anticoagulation (AC) and AC in the treatment of acute proximal deep venous thrombosis (APDVT) of the lower extremities. MethodsThe clinical data of 184 APDVT patients treated in Guizhou Provincial People’s Hospital from January 2017 to December 2022 were retrospectively collected. According to the treatment methods, the patients were divided into CDT group (n=82, CDT combined with AC) and AC group (n=102, AC alone). The prognosis indicators such as the incidence of bleeding events, the incidence of post-thrombotic syndrome (PTS), Villalta score, venous clinical severity score (VCSS) and chronic lower limb venous insufficiency questionnaire (CIVIQ) score were compared between the two groups. ResultsCompared with the AC group, the CDT group had a higher incidence of bleeding events [11.0% (9/82) vs. 2.9% (3/102)], a shorter time to detumescent [(2.8±1.2) d vs. (7.2±1.9) d], and lower VS score [3 (2,4) vs. 3 (2, 7)], VCSS score [2.0 (1.7, 4.0) vs. 3.0 (2.0, 5.2)] and postoperative venous patency score [1 (1, 2) vs. 2 (1, 3)], and higher CIVIQ score [80.0 (77.0, 86.0) vs. 71.5 (68.0, 78.0)], P<0.05. However, there were no significant differences in the incidence of PTS [28.2% (22/78) vs. 36.5% (35/96)] and thrombosis recurrence rate [9.0% (7/78) vs. 11.5% (11/96)] between the two groups (P>0.05). ConclusionCDT can relieve the symptoms and improve the quality of life of APDVT faster than AC, but it is necessary to strictly grasp the indications of thrombolysis to reduce the risk of bleeding.
