Femoral artery ligation for the treatment of femoral artery pseudoaneurysm secondary to drug injection / 中华普通外科杂志

ABSTRACT

Objective To evaluate femoral artery ligation for femoral artery pseudoaneurysm secondary to drug injection. Methods Clinical data of 32 drug addicts of femoral artery pseudoaneursysm caused by drug injection undergoing femoral artery ligation and local debridement were reviewed retrospectively.The blood supply of affected limb was evaluated by oxygen saturation of distal limb and its function.All the cases were followed up at 3,6,9,and 12months after the operation. Results Surgery was successful in all cases. There were no significantly difference of the limb oxygen saturation between postoperative and preoperative period (95.1％ ± 2.8％ vs.96.9％ ± 1.9％ ; t =1.26,P =0.25 ).White blood cells and neutrophils percentage significantly decreased after surgery.All patients were followed up for 1 year.Lower extremity ischemia after 6 hours of operation in one case treated by autologous saphenous vein bypass recovered. On 3 months mild claudication was observed in 5 cases. On 6 months claudication remained in only 2 cases,which disappeared on 9 months.All patients were able to maintain normal life.Conclusions Femoral artery ligation is a safe, effective and simple treatment modality for femoral pseudoaneurysms secondary to drug injection.
