Abstract： Objective To investigate strategies for prevention，early diagnosis，and prompt treatment for acute pulmonary embolism（PE）after video-assisted thoracoscopic surgery（VATS）lobectomy. Methods From January 2007 to November 2010, 1 115 patients with lung cancer underwent VATS lobectomy in the First Affiliated Hospital of Guangzhou Medical College. Among them, 13 patients had acute PE postoperatively, including 6 male patients and 7 female patients with their mean age of 62.3 years（ranging from 42 to 73 years）.All the patients were diagnosed by spiral CT pulmonary artery angiography（SCTPA）, and received anticoagulation therapy with low molecular weight heparin and warfarin. Results The incidence of acute PE after VATS lobectomy was 1.17%（13/1 115）, and the patients with low PE-related early mortality risk accounted for a large proportion（11/13）. There were 12 patients with right-side PE. All the patients’ signs and symptoms were significantly alleviated after administration of anticoagulation therapy. Nine patients received SCTPA review after treatment which showed that their PE had disappeared or been significantly absorbed. No hematological complications including thoracic hemorrhage or wound errhysis occurred after treatment. All surviving patients were followed up for 1 month to 3 months. During follow-up, these patients were alive without PE recurrence. Conclusion SCTPA is the first-choice examination for the diagnosis of acute PE after VATS lobectomy. Prophylaxis against PE and prompt treatment are necessary depending on individual manifestations. VATS lobectomy should be favored as a minimally invasive surgical treatment for patients with lung cancer, for the low incidence of postoperative PE and low PE-related early mortality risk.
ObjectiveTo investigate therapeutic strategy of acute pulmonary embolism. MethodsClinical data of 48 patients with acute pulmonary embolism who were treated in Affiliated Hospital of North Sichuan Medical College form January 2009 to May 2014 were analyzed retrospectively. ResultsOf the 48 cases, 14 cases of low risk (low risk group) were treated with anticoagulation, 24 cases of middle risk (middle risk group) were treated with anticoagulation and systematic thrombolysis or interventional therapy (local thrombolysis after thrombus fragmentation or thrombolytic catheter placement in pulmonary artery), 10 cases of high risk (high risk group) were treated with anticoagulation and interventional therapy. In low risk group, 12 cases (85.7%) were cured and 2 cases (14.3%) were markedly effective, and total effective rate was 100%. In middle risk group, 16 cases (66.7%) were cured and 8 cases (33.3%) were markedly effective, and total effective rate was 100%. In high risk group, 1 case died, 3 cases were cured, 2 cases were markedly effective, and 4 cases were better, and the total effective ratio was 9/10. All cases suffered from no complication such as hemorrhage of cerebral and digestive system. Forty-eight cases were followed up for 3-12 months, with a median time of 8 months. During the follow-up period, there was no complication occurred such as dyspnea, pulmonary embolism, placement change of filter net, and thrombosis. ConclusionsCorresponding therapeutic strategy would be taken according to risk stratification of the acute pulmonary embolism.
摘要:目的:探讨腹腔镜胆囊切除术(laparoscopic cholecystectomy, LC)后发生严重并发症的原因、治疗措施和经验教训。方法:分析 2007 年 8 月至2009 年 4月期间华西医院胆道外科收治的LC术后发生严重并发症的7例患者的临床资料。结果:2例继发性胆总管结石合并化脓性胆管炎患者,采用内镜下十二指肠乳头切开(endoscopic sphincterotomy, EST)取出结石;3例胆道损伤患者,均进行肝门胆管成形和肝总管空肠吻合术;1例绞窄性肠梗阻患者,切除坏死空肠管后,行空肠对端吻合术;以上6例患者均顺利出院,随访8～20个月,均生活良好。1例患者LC术后发生肺动脉栓塞,积极抢救后因呼吸衰竭而死亡。结论:术中仔细轻柔的操作以及辩清肝总管、胆总管与胆囊管的三者关系是预防LC术后发生严重并发症的关键。合理可行的治疗措施是提高发生并发症的患者生活质量的保障。LC术时,胆道外科医生思想上要高度重视,不可盲目追求速度,必要时及时中转开腹。Abstract: Objective: To investigate the causes and therapeutic measures and the experience and lesson of sever complications after laparoscopic cholecystectomy (LC). Methods:Clinical data of 7 patients with severe complications after LC from August 2007 to April 2009 were analyzed retrospectively. The clinical data was got from biliary department of West China Hospital. Results: Two cases of secondary common bile duct stone with acute suppurative cholangitis got cured by endoscopic sphincterotomy. Three cases of severe bile duct injury after LC had stricture of the hilar bile duct, and all of the cases were performed RouxenY hepaticojejunostomy with the diameter of stoma 2.03.0 centimeters. One case of strangulating intestinal obstruction was cured through jejunum endtoend anastomosis after cutting off the necrotic jejunum. All of the above 6 patients recovered well. Following up for 820 months, all lived well. One patient got pulmonary embolism after LC and dead of respiratory failure after active rescue. Conclusion: Carefully making operation and distinguishing the relationship of hepatic bile duct and common bile duct and the duct of gallbladder are the key points to prevent sever complications during LC. Reasonable and feasible treatment is the ensurement of increasing the living quality of the patients with sever complications after LC. And the surgeons of biliary department must have a correct attitude toward LC and should concern think highly during LC and should not pursue speed blindly. In necessary, the operation of LC should be turned into open cholecystectomy.
The high incidence and mortality rates existed in chronic pulmonary thromboembolism(PTE), with considerable misdiagnosis and missed diagnosis rate. The prognosis for patients with chronic thromboembolic pulmonary hypertension was poor with medical therapy. But the pulmonary thromboendarterectomy was well established.The postoperative pulmonary hypertension and reperfusion pulmonary edema are main complications and death causes. The key management after pulmonary thromboendarterectomy is important which decreases pulmonary hypertension , and prevents reperfusion pulmonary edema and re thromboembolism.
ObjectiveTo investigate the safety and efficacy of intermittent pneumatic compression (IPC) in the treatment of deep venous thrombosis (DVT). MethodsThe clinical data of 496 patients with DVT who were treated in our hospital from January 2010 to October 2014 were analyzed retrospectively, to compare the time of venous pressure decreased to normal (T1) and time of circumference difference decreased to normal (T2) in patients received pure therapy (control group) and pure therapy combined with IPC (combination group), according to different types of patients in acute, sub-acute, and chronic phase. In addition, comparison of the remission rate of pulmonary embolism (PE), incidence of PE, and recurrence of DVT was performed between the control group and combination group too. Results① For DVT patients in acute stage, the time of T1 and T2 of patients in central type, peripheral type, and mixed type who received anticoagulant therapy/systemic thrombolysis/catheter thrombolysis+IPC, were significantly shorter than those patients who received only anticoagulant therapy/systemic thrombolysis/catheter thrombolysis (P<0.05). For DVT patients in sub-acute stage, the time of T1 and T2 of patients in central type and mixed type who received anticoagulant therapy/systemic thrombolysis+IPC, were significantly shorter than those of patients who received only anticoagulant therapy/systemic thrombolysis (P<0.05), the time of T1 of patients in peripheral type who received anticoagulant therapy/systemic thrombolysis+IPC, were significantly shorter than those of patients who received only anticoagulant therapy/systemic thrombolysis (P<0.01), but the time of T2 of patients in peripheral type didn't differed between patients who received only anticoagulant therapy/systemic thrombolysis and anticoagulant therapy/systemic thrombolysis +IPC (P>0.05). For DVT patients in chronic stage, the time of T1 and T2 of patients in central type and mixed type didn't differed between patients who received only anticoagulant therapy and anticoagulant therapy +IPC (P>0.05); the time of T1 of patients in peripheral type who received anticoagulant therapy+IPC, were significantly shorter than those of patients who received only anticoagulant therapy (P<0.05), but the time of T2 didn't differed with each other (P>0.05). ② There were 63 patients in control group and 47 patients in combination group had PE before treatment. After the treatment, the PE symptom of control group relieved in 56 patients (88.89%, 56/63) and maintained in 7 patients (11.11%, 7/63), the symptom of combination group relieved in 44 patients (93.62%, 44/47) and maintained in 3 patients (6.38%, 3/47), so the remission rate of PE symptom in combination group was higher (P<0.05). There were 6 patients suffered from new PE in control group[4.26% (6/141)] and 0 in combination group[0 (0/245)] after treatment in patients who hadn't PE before treatment, and the incidence of PE was lower in combination group (P<0.05). ③ There were 325 patients were followed up for 3-36 months with the median time of 27 months, including 157 patents in control group and 168 patients in combination group. During the follow-up period, 74 patients recurred[47.13% (74/157)] in control group and 46 patients recurred[27.38% (46/168)] in combination group, and the recurrence rate was lower in combination group (P<0.05). In addition, 41 patients suffered from post-thrombotic syndrome[26.11% (41/157)] in control group and 27 patients[16.07% (27/168)] in combination group, and the incidence of post-thrombotic syndrome was lower in combination group (P<0.05). ConclusionsIPC can significantly shorten the time of venous pressure and the circumference difference decreased to normal for DVT patients in acute stage and majority DVT patients in sub-acute stage, and it can relieve the clinical symptoms of PE, reduce the incidence rate of PE and recurrence rate of DVT. Therefore, IPC is a safe, reliable, and effective treatment for DVT patients in acute stage and majority DVT patients in sub-acute stage.
