摘要
No consensus has yet been reached regarding the optimal treatment of patients with thromboangiitis obliterans (TO) and chronic limb ischemia. In the present study, we aimed to summarize the results on endovascular treatment of such patients.We performed a meta-analysis using the following databases: PubMed, Scopus, and the Cochrane Library. The eligible studies had been reported up to December 2021 and had evaluated endovascular angioplasty to treat patients with TO and chronic limb ischemia. The early (mortality and technical success) and late (primary/secondary patency and limb salvage) outcomes were evaluated. StatsDirect (StatsDirect Ltd, Merseyside, UK) was used for the statistical analysis.Overall, 15 eligible studies were included (only endovascular in 11 studies and both endovascular and open repair in 4 studies). Among 601 patients, 402 endovascular procedures (416 limbs) were recorded (angioplasty plus stenting for 7.2% and angioplasty plus thrombolysis for 3.7%). The clinical presentation was intermittent claudication (stage II-III) for 7.9% of the patients and critical ischemia (stage IV-VI) for 92.1% of the patients. Most of the patients had had lesions below the knee, and five had had upper extremity lesions. The pooled technical success rate was 86% (range, 81.1%-90.3%), with no in-hospital mortality. The other complications included perforations (1.9%), wound complications (2.2%), and distal embolism (0.2%). Primary patency was 65.7% (range, 52.7%-77.6%) at 12 months and 50.7% (range, 23.3%-77.9%) at 36 months. Secondary patency was 76.2% (range, 57.5%-90.8%) at 12 months and 64.5% (range, 32.3%-90.6%) at 36 months. The limb salvage rate was 94.1% (range, 90.7%-96.7%) at 12 months and 89.1% (range, 80.6%-95.4%) at 36 months.Endovascular angioplasty for patients with TO and chronic limb ischemia was associated with optimal safety and low complication rates. The technical success and late outcomes were acceptable.
