Abstrakt:	Background: To evaluate the rates of limb salvage, survival, and perioperative mortality in patients with acute limb ischemia (ALI) submitted to endovascular revascularization with pharmacomechanical thrombectomy (PMT) and catheter-directed thrombolysis (CDT). Methods: This was a retrospective consecutive cohort study of patients with ALI who were submitted to endovascular treatment with PMT or fibrinolysis at the Division of Vascular and Endovascular Surgery, Hospital do Servidor Público Estadual (São Paulo, Brazil), between July 2015 and December 2018. The limb salvage rate and survival rate at 720 days were analyzed in both the PMT (group 1) and CDT treatment (group 2), as well as the perioperative mortality rate (PMR) at 30 days after surgery. Results: One hundred twelve patients were admitted to the emergency department with ALI between July 2015 and December 2018. Seventeen patients diagnosed with Rutherford III irreversible ALI and 46 patients submitted to open surgery were excluded. Thus, 49 patients were submitted to endovascular surgery; 18 (36.7%) were classified into group 1, and 31 (63.3%) were classified into group 2. The clinical data were equal between the 2 groups, but there was a higher prevalence of thrombophilia in group 1 (3 cases; P < 0.001). The limb salvage rate and the overall survival rate at 720 days were similar between groups 1 and 2 (87.8% vs. 89.7%, P = 0.78 and 84.7% vs. 69.2%, P = 0.82, respectively). There was no statistical difference regarding secondary patency rates at 720 days between groups 1 and 2 (group 1, 81.9% and group 2, 78.8%; P = 0.66). The PMR was 16.7% (8 patients) within the first 30 days. Group 2 had a higher overall mortality rate (OMR) (6 patients, 19.3%, P = 0.03). Regarding the PMT group, there was a higher rate of complications such as myoglobinuria, hematuria, acute renal failure, and death in the subgroup of patients in whom there were performed more than 150 cycles/sec during the surgery (P < 0.001). Conclusions: In the present study, the PMT and CDT endovascular procedures had similar limb salvage, overall survival, and secondary patency rates. However, the OMR was higher in the CDT group. Another important finding was related to the number of cycles/sec performed in the PMT group, in whom patients with more than 150 cycles/sec have presented with higher rates of hematuria, myoglobinuria, acute renal failure, and death.
