Endovascular interventional therapy of lower extremity arterial embolism

Abstract

Objective To investigate the efficacy and safety of endovascular interventional treatment of lower extremity arterial embolism (LEAE).Methods A retrospective analysis on clinical and imaging data was made on 29 LEAE cases.Results In those 29 cases the diagnosis of LEAE was confirmed and embolus extracted by catheter suction.The femoral artery,popliteal artery,anterior tibial artery and tibiofibular bole embolism were in 23,2,3,1 cases respectively.Catheter suction,catheter suction plus thrombolysis,catheter suction plus balloon dilatation,and catheter suction plus stenting treatment were carried out in 17,9,2,1 cases respectively.In all these 29 cases the artery was successfully reopened.In the 9 cases whose distal vessels were embolized by small emboli or thrombosis after initial catheter suction treated by remedy suction and plasminokinase management,artery was completely opened in 4 cases,partially opened in 3 cases,still closed in 2 cases with increased collateral shunts.During follow-up of (18 ± 4) m,lower extremity ischemic symptoms completely disappeared in 23 cases,low skin temperature,pale skin,poor peripheral blood flow were reported in 5 cases,and 1 case had to receive amputation.Conclusions Endovascular interventional treatment is a minimally invasive and safe treatment for LEAE.
