The anatomical distribution of lower extremity deep vein thrombosis after total knee and hip arthroplasty

Abstract

Objective To analyze the anatomical distribution of lower extremity deep vein thrombosis (DVT) after primary total knee arthroplasty (TKA) and total hip arthroplasty (THA).Methods Data of 272 patients with lower extremity DVT confinned by venography after TKA and THA performed from June 2007 to May 2012 in our hospital were retrospectively analyzed.There were 110 cases in TKA group and 162 cases in THA group.The anatomical distribution of lower extremity DVT after TKA and THA was analyzed and compared.Results In TKA group,there were 10 cases of central DVT,6 cases of mixed DVT,and 94 cases of peripheral DVT.In THA group,there were 3 cases of central DVT,19 cases of mixed DVT,and 140 cases of peripheral DVT.There was a significant difference between two groups in the distribution of DVT.In all DVT patients,intramuscular veins were involved most frequently (71.0％,193/272),followed by posterior tibial veins (36.0％,98/272),peroneal veins (31.3％,85/272),anterior tibial veins (8.8％,24/272),popliteal veins (8.8％,24/272),and iliofemoral veins (7.4％,20/272).For patients with peripheral DVT,the isolated DVT was more frequent in THA group,while multiple DVT was more common in TKA group,and the differences were significant between two groups.No isolated DVT was found in anterior tibial veins.In patients with multiple DVT,the thrombi were commonly found in two or three of posterior tibial veins,peroneal veins and intramuscular veins.Conclusion There is a significant difference in the anatomical distribution of DVT after TKA and THA.
