Puerperal ovarian vein thrombosis: evaluation with CT, US, and MR imaging.

Abstract

Five women suspected of having puerperal ovarian vein thrombosis (POVT) were examined with either computed tomography (CT) (five patients), ultrasonography (US) (three patients), magnetic resonance (MR) imaging (one patient), or a combination of these modalities. CT findings included tubular retroperitoneal mass (five patients), periuterine mass (four patients), enlarged uterus (four patients), fluid in the uterus (five patients), central ovarian vein thrombus (four patients), inferior vena cava thrombus (one patient), right hydroureter (one patient), and right ureteral compression (one patient). US findings were similar to CT findings except for an inability to demonstrate the right hydroureter and ureteral compression. MR imaging demonstrated the retroperitoneal mass and central ovarian vein thrombus. CT proved to be superior for the initial evaluation and subsequent diagnosis of POVT. US was useful for follow-up examinations, and MR imaging results confirmed a case of POVT that was suspected following CT.

Spontaneous detorsion of the ovary: Can it be diagnosed by MRI?

“…Ovarian vein thrombophlebitis is associated at surgery with a congestive ovary (10). However, US, CT, and MR reports in the literature emphasize direct visualization of the thrombus and do not describe the ovaries (11,12). No risk factor or clinical or imaging findings suggestive of ovarian thrombophlebitis were present in any of our cases.…”

A rare case of postpartum ovarian vein thrombosis

“…Calderwood et al 3 stated that the right ovarian vein gets easily compressed due to the dextrorotation of the uterus and also due to its entry into the IVC at an acute angle. Savander et al 4 concluded that the right ovarian vein is longer than the left and has many valves within its length, which increases the risk of thrombus formation. Literature 5 also opines that the right ovarian vein is predisposed to thrombosis because there is an anterograde flow in the right ovarian vein, while a retrograde flow is noted in the left ovarian vein immediately after delivery.…”

Septic Pelvic Thrombophlebitis in Differential Diagnosis of Postpartum Acute Abdomen: Case Report

“…5 Ayrıca, gebelikte uterusun dekstropozisyonuna bağlı bu bölgeye olan daha fazla bası ve buradaki venlerde kan akımının farklı özellik göstermesinden ötürü OVT olgularının % 80-90'ında patolojik olay sağ ovarian vende görülür. [4][5][6] Bizim hastamızda da SPT'ye yatkınlık oluşturacak herhangi bir risk faktörü mevcut değildi ve patoloji sağ ovarian vende gelişmişti.…”
