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.
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.
