ABSTRACT
OBJECTIVES:
The objective of this study was to evaluate the effectiveness of percutaneous mechanical thrombectomy as the initial thrombus removal method in the treatment of acute lower extremity ischemia.METHODS:
The patients with acute lower limb ischemia who underwent percutaneous mechanical thrombectomy between August 2016 and February 2018 were retrospectively reviewed. The patients were diagnosed by clinical examination and computed tomography angiography. The percutaneous mechanical thrombectomy was performed as the initial thrombus removal method, followed by anticoagulation therapy. The patients were followed up by clinical examination, imaging, and ankle brachial index (ABI) examination.RESULTS:
Thirty-two patients (21 males, 11 females; average age of 68.53 ± 8.05; three cases of grade III, 29 cases of grade IIB) were reviewed. Recanalization of the thromboembolic occlusions were achieved in all patients. ABI significantly (p < 0.01) increased postoperatively (preoperative ABI 0.51 ± 0.13; postoperative ABI 0.85 ± 0.65, ABI at three months postoperatively 0.84 ± 0.66). Eleven patients underwent balloon dilation and three patients had stent placement. Complete thrombus removal was achieved in all patients. The primary patency at 3 months, 6 months, and 12 months postoperatively was 90%, 85%, and 56%, respectively. The secondary patency at 3 months, 6 months, and 12 months postoperatively was 93%, 87%, and 65%, respectively.CONCLUSIONS:
The immediate result appeared to be effective to use percutaneous mechanical thrombectomy as the first thrombus removal method in the treatment of acute thromboembolic occlusions in the lower extremity, while the midterm result needs to be further improved.Palabras clave
