Abstract:
Objective To observe the value of rheolytic mechanical thrombectomy for treating acute popliteal and infrapopliteal artery thromboembolism.Methods A total of 66 patients with acute popliteal and infrapopliteal artery thromboembolism were retrospectively included,including 31 cases underwent rheolytic mechanical thrombectomy(group A)and 35 underwent manual aspiration thrombectomy through a guide catheter(group B).Clinical data,technical success rate,immediate thrombi clearance grade,complication rates and follow-up vascular patency of the affected limbs were compared between groups.Results No significant difference of patients'baseline characteristics was observed between groups(all P＞0.05).The technical success rates were 100%in both groups.Group A showed higher immediate thrombi clearance rate but lower dosage of urokinase,indwelling time of the thrombolytic catheter and hospital stay than group B(all P＜0.05).The incidence of hemoglobinuria after intervention was higher in group A than in group B(P＜0.05),but no significant difference of bleeding risk nor reperfusion syndrome rates was noticed between groups(both P＞0.05).After treatment,1 patient in group A died due to cardiogenic shock while 2 patients in group B required amputation due to prolonged limb ischemia.Among 63 patients who completed the 12-month follow-up,no significant difference of vascular patency in affected limb was observed among 1,3 nor 6 months post-intervention(all P＞0.05),but group A exhibited higher vascular patency in affected limb than group B at 12 months post-intervention(P＜0.05).Conclusion Rheolytic mechanical thrombectomy could be used to treat lower limb ischemia caused by popliteal and infrapopliteal artery thromboembolism with satisfactory clinical effect.
