Objective To discusses the feasibilities of the hybrid surgical treatment of Stanford type B aortic dissection. Methods From August 2011 to August 2015 a total of 14 cases of complex Stanford type B aortic dissection patients had been completed hybrid surgery. Among them 11 cases of men and 3 cases of women, aged 22 to 62, an average of 44±7.2 years old. Twelve cases with dissecting aneurysm involving the aortic arch and its three vascular branch. There were 2 cases of patients after TEVER, occurred new dissection or pseudoaneurysms, and had hybrid surgery by traditional thoracotomy; 3 cases involving carotid artery were received neck-neck hybrid surgery, and 7 cases involving left subclavian artery were received neck-lock hybrid surgery. Two cases of dissecting aneurysm involving the iliac artery to thrombosis that result in lower limb ischemia, then femoral to femoral artery hybrid surgery were performed. Results All the patients were successfully completed the operation of covered stent implantation and hybrid surgery. Intraoperative angiography showed that the position of the stent was accurate, the interlayer isolation was successful, there was no obvious leakage and displacement of the stent, the true lumen blood flow of the aortic dissection was returned to normal, and bypass blood and target blood vessels were unobstructed. Fourteen patients were followed-up for a period of 3 to 36 months, with an average of (24.0±8.2) months. In 1 month after operation, pleural effusion occurred in 1 case, there was 1 case of cerebral stroke in two days after surgery, incision hematoma occurred in 1 case in 10 days after surgery, and the other patients had no postoperative death and severe complications. All 14 patients were followed-up and returned to normal life. Conclusion The hybrid operations can increase the success rate of TEVAR in complex Stanford type B aortic dissection patients, and early and mid-term results are satisfactory.
Objective To summarize the cl inical experience of vascular bypass grafting combined with endovascularaortic repair (EVAR) for aortic dilatation disease. Methods Between January 2008 and August 2011, 12 patients with aorticdilatation disease were treated with vascular bypass grafting combined with EVAR. Of 12 patients, 11 were male and 1 wasfemale, aged 47-81 years (mean, 65.9 years). All cases were diagnosed through computed tomography angiography (CTA),including 1 case of Stanford type A dissection, 5 cases of Stanford type B dissection, 4 cases of aortic arch aneurysm, and 2 casesof abdominal aortic aneurysm. Eight patients received neck artery bypass grafting before EVAR, and 4 patients underwentfemoral artery bypass grafting after EVAR. Results After operation, pulmonary infection occurred in 3 patients, renalinsufficiency in 2 patients, cerebral infarction in 1 case, decreased hemoglobin and platelets in 7 cases, and poor healing of groinwound in 1 case. Eleven patients were followed up 3-42 months, with an average of 18.6 months. In 1 case undergoing EVARof the thoracic and abdominal aorta, EVAR was performed again because new aneurysms formed at 6 months after operation,and the patient achieved good recovery after 3 months. CTA showed reduced false lumen, thrombosis formation, no endoleak,no deformation or displacement of stent, and anastomotic patency of artificial blood vessels in the other patients at 3, 6, and12 months after operation. Conclusion Vascular bypass grafting combined with EVAR can expand the indications forendovascular repair. It not only provides sufficient anchoring area, but also ensures the blood supply to vital organs, simplifiesthe surgical procedure, and reduces the difficulty of endovascular treatment.
ObjectiveTo assess the causes and risk factors of multiple-intervention in endovascular aortic repair (EVAR) for type B aortic dissection (TBAD). MethodsWe retrospectively analyzed the clinical data of 347 TBAD patients initially treated with EVAR in our hospital between January 1999 and December 2013. The patients were stratified into a multiple-intervention group (34 patients) and a single-intervention group (313 patients). We analyzed the differences of clinical data of the two groups. ResultsThere were 9 patients with endoleak, 10 patients with new dissection, 8 patients with incomplete thrombosis of the false lumen, 4 patients with new aneurysm, 2 patients with retrograde dissection, and 1 patient with iliac artery occlusion in the multiple-intervention group. Higher proportions of chronic dissection and smoking occurred in the multiple-intervention group (79.4% versus 50.8%, 61.8% versus 40.3%, P=0.002, 0.018, respectively). Both of the degree and proportion of hyperglycemia were higher in the multiple-intervention group (6.9±2.3 mmol/L versus 5.7±1.8 mmol/L, P=0.027; 44.1% versus 22.7%, P=0.011). There were statistical differences in oversizing rate of grafts (14.6%±3.2% versus 11.3%±2.5%, P<0.001), operation time (172 min versus 82 min, P<0.001), and blood loss (280 ml versus 100 ml, P=0.006) between the two groups. ConclusionEndoleak, new dissection, and incomplete thrombosis of the false lumen are the main causes of multiple-intervention. While in chronic phase, smoking, hyperglycemia, too big oversizing, and complicated lesion or operation are the potential risk factors.
Objective To explore the predictive value of neutrophil-to-lymphocyte ratio (NLR) in peripheral blood for postoperative complications of elective endovascular repair for abdominal aortic aneurysm (AAA). Methods From August 2016 to November 2021, the clinical data of patients with AAA who received endovascular isolation repair for the first time in the Department of Vascular Surgery of Beijing Hospital were retrospectively analyzed, including the basic information of the patients, comorbid diseases, and the largest diameter of AAA, preoperative blood labotry test, postoperative complications, long-term survival rate and other indicators. The optimal NLR in peripheral blood was determined, and the differences in postoperative complications and long-term survival rates between the high NLR group and the low NLR group were analysed. Results A total of 120 patients with AAA underwent endovascular isolation for the first time were included in this study, including 105 males and 15 females. The age ranged from 52 to 94 years, with an average of (73.3 ± 8.26) years. The largest diameter of abdominal aortic aneurysm was 35 to 100 mm, with an average of (58.5 ± 12.48) mm. The best cut-off value of NLR for predicting postoperative complications of AAA was 2.45 by using Yoden index screening. Those with NLR ≥2.45 were in the high NLR group (n=66), and those with NLR <2.45 were in the low NLR group (n=54). There was no statistically significant difference between the two groups in the incidence of overall complications and the incidence of sub-complications (P>0.05). The results of logistic regression analysis suggested that NLR was an independent risk factor for complications after endovascular repair of AAA (P<0.05). The median survival time of patients in the high NLR group and the low NLR group was 31.47 months and 35.28 months, respectively, and there was no statistically significant difference between the two groups (P>0.05). Conclusion NLR can be used as a reference predictor of complications after elective endovascular repair of AAA, but more research results are still needed to confirm.
