BACKGROUND: Whether pharmaco-mechanical thrombolysis (PMT) results in superior outcomes to catheter-directed thrombolysis (CDT) in treating thrombotic or embolic arterial occlusion of the lower limbs is unclear.
METHODS: We enrolled 94 patients with Rutherford class I-IIb due to thrombotic or embolic arterial occlusion in the lower limbs and who received emergency endovascular treatment. Baseline demographics, laboratory data, angiography and clinical outcomes were collected through chart reviews and fluoroscopic imaging. The procedural characteristics (thrombolytic drug dosage, treatment duration, and additional procedures), immediate angiographic outcomes (patency of calf vessels, and complete lysis), complications (major bleeding, and fasciotomy), and primary composite end-points (30-day mortality, amputation, and reocclusion) were compared between patients who received CDT versus PMT.
RESULTS: Compared with CDT, PMT was independently associated with lower total UK dosage (standardized coefficient β=- 0.44; P<0.01) and higher prevalence of complete lysis (odds ratio =1.78, 95% confidence interval: 1.03-3.06; P=0.04) after adjustments of covariates. The PMT group had significantly shorter treatment duration (23.00 [7.25-39.13] vs. 41.00 [27.00-52.50]; P<0.01). No significant intergroup differences were observed for the primary composite end point (10.7% vs. 9.1%; P=0.81), or prevalence of the major bleeding (9.1% vs. 0.0%; P=0.10) despite the PMT group comprising patients with more advanced chronic kidney disease and more diffuse thrombosis.
CONCLUSIONS: PMT with a Rotarex is a safe and effective strategy for treating thrombotic or embolic lower limb ischemia. It significantly reduced the thrombolytic drug dosage, and resulted in the complete lysis being more likely.
