title: The natural history and treatment outcomes of symptomatic ovarian vein thrombosis.
abstract: BACKGROUND
  Information on ovarian vein thrombosis (OVT) is limited to some retrospective studies. The purpose of this prospective study was to evaluate the natural history and treatment outcomes of OVT.
  
  
  METHODS
  Patients with documented symptomatic OVT who were treated with anticoagulation and had at least 3 months of follow-up were included. Outcomes of interest were recanalization rates, pain resolution, pelvic congestion syndrome, recurrent deep venous thrombosis (DVT), and mortality. All patients underwent clinical examination and duplex ultrasound; computed tomography venography was selectively performed.
  
  
  RESULTS
  There were 23 women with a mean age of 44 years (range, 23-68 years). Fifteen (65%) right, 5 (22%) left, and 3 (23%) bilateral OVTs were detected. The median follow-up was 27 months (range, 3 months-7 years). The most common presentation was abdominal pain in nine patients (39%), followed by flank pain in six (26%). Two patients (9%) presented with dyspnea due to pulmonary embolism. The most prevalent condition was the puerperium (n = 9; 39%). Complete recanalization occurred in 16 veins (61%), partial recanalization in four veins (15%), and occlusion in six veins (24%) while patients were receiving anticoagulation. Four patients (17%) had lower extremity DVT during follow-up after the interruption of anticoagulation. Three patients (13%) developed pelvic congestion syndrome. All four deaths (17%) were due to cancer-related complications.
  
  
  CONCLUSIONS
  Symptomatic OVT is rare. Patients fare well with anticoagulation; complete recanalization occurs in about two thirds of the patients. Recurrent DVT is found in lower extremity veins after the interruption of anticoagulation in 17% of patients; mortality was seen only in cancer patients.
