  • Endovascular Therapy for TASC-ⅡC/D Lesion of Iliac Artery Occlusion

    ObjectiveTo investigate the therapeutic effect of endovascular therapy for TASC-ⅡC/D lesion of iliac artery occlusion. MethodThe clinical data of 25 patients (28 limbs) who underwent endovascular therapy for TASC-ⅡC/D lesions of iliac artery occlusion were reviewed retrospectively. ResultsTwo limbs failed to recanalize the occlusions, recanalization rate was 92.86%. Twenty-six iliac arteries were successfully treated by percutaneous transluminal angioplasty and implanted stent. The ankle-brachial index increased from preoperative 0.23±0.18 to postoperative 0.76 ±0.19 (P < 0.05). Two patients had hematomas in puncture point, which were improved by conservative treatment. One patient had thrombosis in stent, which was disappeared by local thromblysis after thrombolytic catheter placement. Twenty patients (24 iliac arteries) were followed up for a mean time of 8 months (3-24 months). The follow-up rate was 85.71%. The limb patency rates of 6 months, 1-and 2-year was 85%, 80% and 73%, respectively. ConclusionEndovascular therapy for TASC-ⅡC/D lesion of iliac artery occlusion is safe and has a good short-term therapeutic effect, microtrauma and little complications.

  • Strategies of Endovascular Repair for Complicated Stanford Type B Aortic Dissection

    ObjectiveTo investigate the therapeutic strategies of endovascular repair for complicated Stanford type B aortic dissection. MethodThe clinical data of 36 patients with complicated Stanford type B aortic dissection treated by endovascular repair were analyzed retrospectively. ResultsThirty-six patients with complicated Stanford type B aortic dissection were treated successfully by endovascular repair. Twenty-two cases were treated by endovascular repair combined with covering left subclavian artery (LSA). Ten cases were treated by endovascular repair combined with chimney technique. Two cases were treated by endovascular repair combined with vascular prosthesis bypass from left common carotid artery to LSA. Two cases were treated by endovascular repair combined with vascular prosthesis bypass from right common carotid artery to left common carotid artery, whose proximal part were ligated. The viscera artery and lower extremity artery supply were restored gradually. No complication such as endoleak occurred. ConclusionFor endovascular repair of complicated Stanford type B aortic dissection, strategies combined with covering LSA, chimney technique, and hybrid operation of small incision could extend anchor zone, expand the range of endovascular repair of aortic dissection, improve curative effect, reduce complications.

  • Therapeutic Strategy of Acute Pulmonary Embolism: Analysis of 48 Cases

    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.
