Abstract:
Objective To evaluate risks of symptomatic pulmonary embolism (PE) in deep vein thrombosis (DVT) patients complicating iliac vein compression syndrome (IVCS).Methods Between January 2010 and January 2015,patients diagnosed with lower extremity DVT and IVCS at our institution were included.The odds of symptomatic PE versus lower extremity DVT complicated with IVCS were assessed using Logistic regression models.Its association with age,gender,thrombophilic risk factors,degree of stenosis,filter implantation and symptomatic PE were assessed.Results Of 759 patients,410 patients had inferior vena cava (IVC) filters implanted and 349 had not.In filter placement group,3 patients suffered from symptomatic PE among 32 with thrombi intercepted in IVC filters.In the group with no IVC filters placement,39 cases suffered from symptomatic PE.Symptomatic PE was in positive correlation to respiratory disease and right lower extremity DVT,and negative correlation to IVC filter implantation.Conclusions In lower extremity DVT patients complicated with IVCS,the right lower extrenity DVT and respiratory disease are risk factors of symptomatic PE.IVC filter implantation prevents symptomatic PE from happening in most patients.
