  OBJECTIVE: To estimate the frequency of ovarian vein thrombosis (OVT) after oophorectomy and to identify comorbidities.

STUDY DESIGN: A retrospective review of patients who underwent oophorectomy between January 2008 and December 2009. Overall, 195 patients were identified; 9 patients were excluded for being on anticoagulation preoperatively. Eighty-nine patients underwent postoperative abdominal computed tomography imaging within 18 months postoperatively. Patient characteristics, operative details, and perioperative morbidities were analyzed. A radiologist reviewed the scanned images and identified OVT. Statistical analyses were performed using univariate Fisher’s exact tests for categorical variables and Wilcoxon rank-sum tests for continuous variables. Statistical significance was set at p<0.05.

RESULTS: Twelve (13.4%) of the patients had OVT diagnosed. Three were diagnosed with a pulmonary embolus in the ovarian thrombosis group. On univariate analysis, OVT was associated with a longer hospital stay (p=0.013) and otherwise was not associated with an increased risk of other complications. Specifically, there was no temporal cause and effect association between OVT and pulmonary embolism.

CONCLUSION: OVT after oophorectomy was less frequent in this study than previously reported. There was no temporal association to suggest that OVT leads to pulmonary embolization or other complications.
