Giant varicose Inferior Mesenteric Vein
European Journal of Radiology Extra, 2002Co-Authors: Erol Akgül, Mehmet Inal, Kairgueldy Aikimbaev, Mustafa Celiktas, Erol AksungurAbstract:Abstract In portal hypertension, a variety of portocaval collateral pathways develops in attempt to decompress the portal circulation. The most common collateral pathway is the coronary-gastroesophageal route. Here we report a case of portocaval anastomosis of Inferior Mesenteric Vein (IMV) reaching to iliac Veins via hemoroidal Veins with the findings on ultrasonography, computed tomography (CT) and splenoportography. The route of this portocaval anastomoses is not frequent and the huge caliber of IMV is unusual in our case.

successful use of the Inferior Mesenteric Vein for renal transplantation
American Journal of Transplantation, 2003Co-Authors: Pratik Patel, Venkatesh KrishnamurthiAbstract:For renal transplantation, the standard venous drainage of the allograft is via the iliac Vein. In unusual circumstances, such as thrombosis or agenesis of the iliac Veins and the Inferior vena cava, portal venous drainage may be a suitable option. We report a case in which the Inferior Mesenteric Vein was used for venous drainage of a cadaveric renal allograft.

balloon occluded retrograde transvenous obliteration brto for a direct shunt between the Inferior Mesenteric Vein and the Inferior vena cava in a patient with hepatic encephalopathy
Journal of Vascular and Interventional Radiology, 2007Co-Authors: Kenji Ibukuro, Toru Sugihara, R Tanaka, Hozumi Fukuda, Kimiko Tobe, Ryosuke Tateishi, Kazumi TagawaAbstract:A direct shunt between the Inferior Mesenteric Vein and the Inferior vena cava was detected in a patient with hepatic encephalopathy. The authors performed balloon-occluded retrograde transvenous obliteration (BRTO) for this shunt. Before the obliteration, the shunt was occluded by using a balloon catheter and it was confirmed that the portal venous flow was redirected to the liver. The encephalopathy disappeared immediately after BRTO. The improvement of the liver function, the disappearance of the shunt, and the increase in the size of the portal Vein and liver volume were confirmed at computed tomography performed 5 months after treatment.

Huge Varicose Inferior Mesenteric Vein: an Unanticipated ^99m Tc-labeled Red Blood Cell Scintigraphy Finding
Nuclear Medicine and Molecular Imaging, 2010Co-Authors: Samaneh Hoseinzadeh, Babak Shafiei, Mohamadtaghi Salehian, Isa Neshandar Asli, Iraj GhodoosiAbstract:Ectopic varices (EcV) are enlarged portosystemic venous collaterals, which usually develop secondary to portal hypertension (PHT). Mesocaval collateral vessels are unusual pathways to decompress the portal system. Here we report the case of a huge varicose Inferior Mesenteric Vein (IMV) that drained into perirectal collateral Veins, demonstrated by ^99mTc-labeled red blood cell (RBC) scintigraphy performed for lower gastrointestinal (GI) bleeding in a 14-year-old girl. This case illustrates the crucial role of ^99mTc-labeled RBC scintigraphy for the diagnosis of rare ectopic lower GI varices.

splenic Vein Inferior Mesenteric Vein anastomosis to lessen left sided portal hypertension after pancreaticoduodenectomy with concomitant vascular resection
Archives of Surgery, 2011Co-Authors: N Ferreira, Elie Oussoultzoglou, Pascal Fuchshuber, Dimitrios Ntourakis, Masato Narita, Mudassir Rather, Edoardo Rosso, Pietro Addeo, Patrick Pessaux, Daniel JaeckAbstract:Hypothesis A splenic Vein (SV)–Inferior Mesenteric Vein (IMV) anastomosis reduces congestion of the stomach and spleen after pancreaticoduodenectomy with resection of the SV–Mesenteric Vein confluence but carries a risk of left-sided venous hypertension. Design Comparative retrospective study. Setting Department of Digestive Surgery and Transplantation, University of Strasbourg, Strasbourg, France. Patients From January 1, 2002, to February 28, 2010, 39 patients underwent pancreaticoduodenectomy with resection of the SV–Mesenteric Vein confluence for pancreatic adenocarcinoma. All patients had a terminoterminal portal Vein–superior Mesenteric Vein anastomosis. The SV blood flow into the portal Vein was preserved in 11 patients by reimplantation of the SV into the portal Vein. Sixteen patients underwent surgical reconstruction of the SV-IMV confluence by anastomosis (group 1), and in 12 patients the natural SV-IMV confluence was preserved (group 2). Main Outcome Measures Preoperative and postoperative spleen volume and platelet count. Results Demographic characteristics, preoperative tumor staging, pathological outcome, and postoperative complications were comparable in both groups. There was no difference in platelet count between groups 1 and 2 preoperatively (mean [SD], 293.13 [125.37] vs 241.09 [49.12] × 10 3 /μL [to convert to ×10 9 /L, multiply by 1.0], respectively; P = .21) or postoperatively (mean [SD], 231.75 [156.39] vs 164.31 [76.46] × 10 3 /μL, respectively; P = .32). Likewise, no difference was found in the spleen volume preoperatively (mean [SD], 258.96 [179.23] vs 237.31 [122.46] mL, respectively; P = .76) and on postoperative day 15 (mean [SD], 279.08 [158.10] vs 299.12 [153.11] mL, respectively; P = .78). Conclusion Early assessment shows that SV-IMV anastomosis is as feasible and as safe as the preservation of a natural SV-IMV confluence in patients undergoing pancreaticoduodenectomy with vascular resection for pancreatic head adenocarcinoma.

Splenic Vein–Inferior Mesenteric Vein Anastomosis to Lessen Left-Sided Portal Hypertension After Pancreaticoduodenectomy With Concomitant Vascular Resection
