Renal Transplantation to the Ovarian Vein: A Case Report

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 5 2008
V. K. H. Wong
Renal failure patients with absent or thrombosed inferior vena cava (IVC) and iliac veins are considered technically unsuitable for transplantation. Occasional cases have been reported in literature of transplant using inferior and superior mesenteric veins. We describe a case in which kidney was transplanted on to an ovarian vein in a young patient who had thrombosed IVC and iliac veins and was previously declared unsuitable for transplantation.

Doppler studies of the ovarian venous blood flow in the diagnosis of adnexal torsion

JOURNAL OF CLINICAL ULTRASOUND, Issue 8 2009
Khatib Nizar MD
Abstract Purpose. To evaluate the role of ovarian Doppler studies in diagnosing adnexal torsion. Methods. We included in that study all patients who had an adnexal mass with clinical symptoms of intermittent lower abdominal pain and were hospitalized for at least 48 hours of observation. Our protocol included: measurements of the size of the adnexal mass, presence or absence of ovarian edema, presence or absence of adnexal vascularity, presence or absence of ovarian artery flow, presence or absence of ovarian venous flow, pattern of ovarian venous flow. The ovarian artery and vein were sampled just above and lateral to the adnexa. Sensitivity, specificity, and positive and negative predictive values in the diagnosis of adnexal torsion were calculated for each of the gray-scale and Doppler sonographic (US) findings. Results. One hundred and ninety-nine patients presented with adnexal mass and intermittent lower abdominal pain. Sensitivity and specificity of tissue edema, absence of intra-ovarian vascularity, absence of arterial flow, and absence or abnormal venous flow in the diagnosis of adnexal torsion were: 21% and 100%, 52% and 91%, 76% and 99%, and 100% and 97%, respectively. All patients with adnexal torsion had absent flow or abnormal flow pattern in the ovarian vein. In 13 patients, the only abnormality was absent or abnormal ovarian venous flow with normal gray-scale US appearance and normal arterial blood flow. Of these 13 patients, 8 (62%) had adnexal torsion or subtorsion. Conclusion. Abnormal ovarian venous flow may be the only abnormal US sign observed during the early stage of adnexal torsion. © 2009 Wiley Periodicals, Inc. J Clin Ultrasound 2009 [source]

Use of time resolved magnetic resonance imaging in the diagnosis of pelvic congestion syndrome

JOURNAL OF MAGNETIC RESONANCE IMAGING, Issue 3 2010
Tarun Pandey MD
Abstract We describe the efficacy of time-resolved MR angiography in diagnosing a case of pelvic congestion syndrome (PCS). MR angiography, using four-dimensional (4D) TRAK (Time-Resolved Angiography using Keyhole) technique was used in an 81-year-old woman presenting with low backache, pelvic pain, and left pelvic fullness. Dynamic images were obtained in multiple vascular phases including arterial, arteriovenous, and venous phases. The high temporal resolution of 4D TRAK could demonstrate early retrograde left ovarian vein filling as well as multiple dilated pelvic varices, allowing the prospective diagnosis of PCS to be made. Although uncommon in this age group, the diagnosis was subsequently confirmed on conventional catheter venography with symptomatic relief after successful embolization of the incompetent left ovarian vein. The MRA and correlative catheter venography images are presented in this case report. J. Magn. Reson. Imaging 2010;32:700,704. © 2010 Wiley-Liss, Inc. [source]

Successful adult-to-child renal transplantation utilizing the ovarian vein in children with inferior vena cava/iliac vein thrombosis

Tao R, Shapiro R. Successful adult-to-child renal transplantation utilizing the ovarian vein in children with inferior vena cava/iliac vein thrombosis. Pediatr Transplantation 2010: 14:E70,E74. © 2009 John Wiley & Sons A/S. Abstract:, IVC/iliac vein thrombosis has previously been considered to be a contraindication to renal transplantation because of the technical difficulties and the increased risk of graft thrombosis. We report two successful cases of adult-to-child kidney transplantation in which we anastomosed the graft renal vein to the recipient ovarian vein in the presence of IVC and/or iliac vein thrombosis, with no short or long term vascular complications. Our experience, which adds to the successful reports from several other centers, suggests that the inability to use the iliocaval axis should no longer be considered a contraindication to pediatric renal transplantation.
