OBJECTIVES AND DESIGN: Popliteal vein repair and ligation are the two main approaches to the treatment of the venous component of major, complex, knee injuries with vascular involvement. We have studied the incidence of @entity1151 following popliteal vein repair in @entity130 cases using computed tomography (CT) angiography and report the outcome. MATERIAL AND METHODS: From June 2006 to December 2009, 45 @entity1 with @entity130 were operated on in our vascular unit using lateral venorrhaphy, end-to-end @entity254 , a saphenous vein interposition graft and venous patch repair. All the @entity1 were operated on using a medial approach to the knee. On the third postoperative day, all @entity1 underwent a colour Doppler scan of the repaired popliteal vein to study patency, and pulmonary artery CT angiography using a 64-slice multidetector CT scan unit to establish the incidence of @entity1151 . RESULTS: The number of @entity1 treated by each method were: lateral venorrhaphy 20 (44%), end-to-end @entity254 13 (29%), saphenous vein interposition graft 9 (20%) and venous patch repair three (7%). Two @entity1 (4%) died because of @entity1576 the day after surgery with massive @entity1151 at autopsy. Popliteal colour duplex ultrasound imaging showed seven (16%) cases of @entity715 and seven (16%) cases of partial vein @entity715 . CT angiography showed @entity1151 in 11 (26%) @entity1 . From seven @entity1 with complete @entity715 three @entity1 , and from seven @entity1 with incomplete @entity715 five @entity1 showed @entity1151 on CT angiography. Other than two cases of early mortality, five (12%) @entity1 developed clinical manifestations of @entity1151 and 11 (26%) @entity1 had @entity1151 detected by CT angiography. Seven (16%) of our @entity1 had mild-to-severe @entity1151 and 13 @entity1 (29%) had proven @entity1151 . The total mortality rate was 7%. CONCLUSION: A surprisingly high incidence of @entity1151 was observed after popliteal vein repair in civil @entity130 @entity1 . Additional prophylactic methods such as using higher doses of heparin and using inferior vena cava (IVC) filters might be needed to prevent this potentially fatal complication.
