  • Application of retrievable vena cava filter in patients with lower limb fractures complicated with deep venous thrombosis

    ObjectiveTo explore the value of recombinant inferior vena cava filter (IVCF) in the prevention of perioperative pulmonary embolism in patients with lower limb or pelvic fracture combined with deep venous thrombosis (DVT).MethodsThe clinical data of 168 patients with lower limb or pelvic fracture combined with DVT were analyzed retrospectively.ResultsThe filters were successfully implanted in 168 patients, and the recoverable filters were removed after (48.3±4.8) d (14–97 d). The filters were removed successfully in 159 cases, and the removal rate was 94.6%. Sixty-one cases were found to have thrombus on the filter after contrast examination or removal of vena cava filter, that is, the thrombus interception rate was 36.3%.ConclusionFor patients with lower limb or pelvic fracture combined with DVT, the rechargeable vena cava filter can effectively stop thrombosis and avoid pulmonary embolism.

  • Analysis of Risk Factors for Acute Lower Deep Venous Thrombosis in Patients

    ObjectiveTo investigate the risk factors for lower limbs deep venous thrombosis(LDVT), and provide reference for the prevention and treatment of LDVT. MethodsThe pathogenic factors of 187 patients with LDVT in our hospital from 2010 to 2013 were retrospectively analyzed. ResultsOne hundred and eighty-seven patients with LDVT were 19-88 years old, mean 56.6 years old, and the age of onset was many in the 41-60 years old(65.2%). In 187 cases, male 102 cases, female 85 cases; left lower extremity in 112 cases, right lower extremity in 65 cases, and 10 cases of double lower limbs. LDVT predisposing factors were the lower extremities a history of fracture, surgery, tumor, bedridden, previous history of blood clots, and a small amount of internal diseases of unknown cause. ConclusionsLDVT occurs at 41-60 years old. The surgery, tumor, and history of thrombosis are independent risk factor of LDVT.

  • Improvement of Visceral Arterial Blood Supply after Thoracic Endovascular Aortic Repair for Stanford Type B Aortic Dissection

    ObjectiveTo investigate the improvement of visceral arterial blood supply after thoracic endovascular aortic repair (TEVAR) for patients with Stanford type B aortic dissection (AD). MethodsWe retrospectively analyzed clinical data of 35 patients with Stanford type B AD undergoing TEVAR in Mianyang Central Hospital from January 2013 to March 2014. There were 30 male and 5 female patients with their age of 45-82(62.5±10.0) years. Among the 140 main visceral arteries (celiac artery, superior mesenteric artery, left and right renal arteries) of the 35 patients, blood supply of 79 arteries were compromised, including 36 arteries with stenosis and blood supply via the true lumen, 18 arteries with blood supply via both true and false lumen, 18 arteries with blood supply via the false lumen, and 7 arteries without blood supply. Improvement of blood supply of main visceral arteries was analyzed. ResultsAll the operations were successfully performed without in-hospital death. Operation time was 97.8 (68-147) minutes, length of ICU stay was 12-34 h, and length of hospital stay was 10-21 days. None of the patients had cerebral infarction, acute renal failure, AD rupture or stent migration after TEVAR. Blood supply of the compromised visceral arteries showed improvement in various degrees. ConclusionFor the treatment of Stanford type B AD, TEVAR can not only successfully block the rupture of AD, but also improve blood supply of main visceral arteries, avoid or reduce the complications resulting from compromised visceral arterial blood supply and visceral ischemia.

  • Applications capture technology in larger abdominal aortic aneurysm surgery performed during endovascular repair of abdominal aortic aneurysm

    Objective To summarize the clinical experience of capture technology in the large diameter of abdominal aortic aneurysm in endovascular repair of abdominal aortic aneurysm(EVAR). Methods We retrospectively analyzed clinical data of 6 patients with abdominal aortic aneurysm (maximum diameter of 6.0 cm or bigger) in our hospital between July 2013 and May 2014.There were 3 males and 3 females at age of 76.2(73–81) years. Two patients of ruptured abdominal aortic aneurysm, in EVAR, established orbit using the capture technology successfully. Results The capture technology made the thread through the proximal tumor neck smoothly, successful repaired. One patient of rupture of abdominal aortic aneurysm was dead after 10 hours. One patient was lost to follow-up. Four patients were followed up for 3 to 11 months. The four patients had not occurred bracket displacement, internal leakage, thrombosis, or other serious complications. Conclusion For the patients with larger abdominal aortic aneurysm, capture technology may be used to the thread through the proximal tumor neck, to build a convey or track easily, to shorten the operation time, to improve the success rate of surgery.

  • Clinical Analysis of Autogenous Arteriovenous Fistulae in Elbow

    目的探讨为维持性血液透析患者行肘部动静脉内瘘的手术方法及技巧。 方法回顾性分析我院2009年8月至2012年8月期间行肘部动静脉内瘘68例患者的临床资料。 结果68例患者手术均成功。所有患者术后血流量都能满足血液透析需要,无感染、皮下血肿等并发症。随访至今,未发现血管内血栓形成、造瘘口狭窄等。 结论对于腕部自体动静脉不能行造瘘术时,肘部动静脉内瘘为血液透析患者提供了一条新的血管通路。
