Surgical treatment for chronic lower limb ischemia: A report of 60 cases

Abstract

Objective To explore the clinical characteristics and treatment strategy of chronic lower limb arterial ischemic. Methods The clinical data of 60 patients with chronic lower limb arterial ischemic-treated from January 2017 to May 2017 were analyzed retrospectively (63 affected limbs). According to the patient's physical condition, clinical symptoms and pathological features, individualized surgical treatment was selected, including autogenous great saphenous vein or artificial blood vessel bypass grafting, artery intima stripped, balloon dilatation, stenting, intracavity volume reduction, or hybrid procedures. The ankle brachial index of preoperative and postoperative 3 months was monitored, and patients were classified according to the Rutherford classification standard. Results Sixty cases were underwent surgery treatment, three patients were treated with bilateral lower limbs in the same period, successfully 58 cases and success rate reached 96.67%. One case was subjected to amputation, and 1 case died (cardiovascular disease). Postoperative 3 month follow-up, the Rutherford grading of 59 affected limbs was improved markedly, average ankle brachial index of postoperative was higher than preoperative (P<0.05). Six cases of patients with ulcer were cured, the ulcer surface of 2 cases were significantly narrowed. Conclusions The incidence of chronic lower limb arterial ischemic is increasing year by year, the treatment ideas are constantly updated. It is safe and effective to select individualized treatment according to the patients' physical condition, clinical symptoms and pathological feature. However it still needs to enlarge the sample and extend the time of follow-up to verify this point. Key words: Ischemia/SU; Lower extremity/PA
