Venous thromboembolism (vte) is considered as one of the leading causes ofmaternal mortality during pregnancy and postpartum period. in this retrospective studythe medical records of 81 women diagnosed with pulmonary thromboembolism (pte) anddeep venous thrombosis (dvt) between 2009 and 2012 in tabriz al-zahra hospital wasparticipated. these cases were evaluated regarding frequency, maternal and fetus riskfactors associated with vte. during 3 years 33 patients were diagnosed as pte; 7 womenwere diagnosed as dvt and pte; and 41 women were diagnosed as dvt. most frequentunderlying disease was hypertension (13.5%) and most frequent symptoms of pte and dvtwere dyspnea (100%) and swelling of lower limb (100%) respectively. 93% of pte and 79%of dvt incidences occurred during and after the third trimester of pregnancy.additionally, 38% of pte occurred during or after childbirth (33% following cesareanand 5% following vaginal delivery). therefore, it seems that vaginal delivery is saferthan cesarean surgery. in addition, the importance of third trimester of pregnancy andpostpartum period is obvious.
