BACKGROUND: DIPS is to create a portosystemic shunt directly between the portal vein and the retrohepatic inferior vena cava (RIVC) without passing through the hepatic vein. It has been recommended that the DIPS could be applied when routine TIPS is unsuccessful or the patient has anatomical variations of the hepatic ...

Transjugular intrahepatic portosystemic shunt (TIPS) creation is an accepted treatment for portal hypertension. TIPS creation remains a challenging procedure because it involves the successful passage of a needle from a point of origin (hepatic vein) to a target point (portal vein) through the liver substance. An understanding of the anatomy ...

Arteriogenesis or collateral growth is able to compensate for the stenosis of major arteries. Using differential display RT-PCR on growing and quiescent collateral arteries in a rabbit femoral artery ligation model, we cloned the rabbit full-length cDNA of osteoglycin/mimecan. Osteoglycin was present in the adventitia of collateral arteries as a ...

Common bile duct stenosis owing to extrahepatic portal varices is termed "portal hypertensive biliopathy" (PHB) and is a rare occurrence. We report a case of PHB owing to portal vein thrombosis with cavernous transformation successfully managed by mesocaval shunt and endoscopic retrograde cholangiopancreatography (ERCP) biliary stent placement. A 44-year-old male, ...

Thrombosis of the portal venous system is a well-recognized and potentially lethal complication after open or laparoscopic splenectomy. A 7-year-old girl with idiopathic thrombocytopenic purpura developed a portal vein thrombosis after open splenectomy. The portal vein thrombosis was diagnosed by color Doppler sonography. A percutaneous transhepatic thromboaspiration of the acute ...

Acute symptomatic portal vein obstruction related to biliary stenting is an extremely rare but life-threatening complication. This usually occurs in patients with either tumor invasion into the portal vein or pre-existing portal vein thrombus. Therefore, the portal vein should be carefully evaluated before placing a biliary metallic stent in such ...

A case of intrahepatic arteriovenous malformation connected with umbilical, hepatic, portal, and arterial systems in a fetus diagnosed at 36 weeks of gestation is presented. Prenatal color Doppler ultrasonography in the fetal liver demonstrated complicated vascular connections fed by arterial and portal branches. Postnatal color Doppler, power Doppler, 3D power ...

Portal vein thrombosis secondary to protein C deficiency is a rare finding. Diagnosing a portal vein thrombosis itself is difficult due to nonspecific symptoms such as nausea, vomiting, anorexia, and weight loss. Proving that a protein C deficiency is the cause of a portal vein thrombosis is even more difficult ...

In vascular smooth muscle, store-operated channels (SOCs) contribute to many physiological functions including vasoconstriction and cell growth and proliferation. In the present work we compared the properties of SOCs in freshly dispersed myocytes from rabbit coronary and mesenteric arteries and portal vein. Cyclopiazonic acid (CPA)-induced whole-cell SOC currents were sixfold ...

BACKGROUND/AIMS: Permanent portal vein embolization (PVE) is a widely practised technique. The use of an absorbable material would be safer in clinical situations in which the embolized liver is not resected. We evaluated the efficiency of reversible PVE in terms of liver regeneration and analyzed the precise time course of ...

Congenital hepatoportal arteriovenous fistula is a rare cause of portal hypertension in young children. Unlike the acquired form, which is usually isolated and can be cured by hepatic artery (HA) embolization, recurrence of portal hypertension often occurs with congenital hepatoportal arteriovenous fistula after embolization and/or HA ligation because of early, ...

Splenic artery embolization (SAE) improves hepatic artery (HA) flow in liver transplant (OLT) recipients with so-called splenic artery steal syndrome. We propose that SAE actually improves HA flow by reducing the HA buffer response (HABR). Patient 1: On postoperative day (POD) 1, Doppler ultrasonography (US) showed patent vasculature with HA ...

Dying in a head-down position is rare, and autopsy may reveal no morphological findings which can sufficiently explain the cause of death. The authors describe a case of positional asphyxia of a 78-year-old man, found dead hanging in head-down position inside a blackberry bush. The subject was suspended by his ...

Portal vein thrombosis (PVT) is observed in 10-20% of patients with liver cirrhosis, which is responsible for 20% of all PVT cases. The main pathogenic factor of PVT in cirrhosis is the obstacle to portal flow, but acquired and inherited clotting abnormalities may play a role. The formation of collateral ...

We describe a case of duodenal varices successfully treated with balloon-occluded retrograde transvenous obliteration (BRTO) alone. A 63-year-old man presented with tarry stools. Computed tomography demonstrated dilated varices around the duodenum. Emergency endoscopic examination revealed varices of the second portion of the duodenum without active bleeding. There was no evidence ...

OBJECTIVE: The purpose of this study was to adapt and improve a minimally invasive two-step postmortem angiographic technique for use on human cadavers. Detailed mapping of the entire vascular system is almost impossible with conventional autopsy tools. The technique described should be valuable in the diagnosis of vascular abnormalities. MATERIALS ...

Portal vein thrombosis is a rare but well-known complication after abdominal surgery. To our knowledge, there have been no reports about this complication after cardiopulmonary bypass surgery. This can probably be explained by the variety of clinical pictures and difficulties in the establishment of a diagnosis of portal vein thrombosis. ...

Intravascular papillary endothelial hyperplasia (Masson's vegetant hemangioendothelioma) is a rare condition affecting the arteries. In the literature, we did not find any reference to this lesion involving the humeral artery. We present a case of asymptomatic humeral artery vascular tumor due to this abnormality. A 58-year-old woman was admitted to ...

Hepatic vein resection and reconstruction after major hepatectomy is a technically feasible but controversial procedure. Reported autologous vein grafts include the great saphenous, external iliac vein, superficial femoral, gonadal, left renal and inferior mesenteric veins. The procedures required to obtain these grafts, however, are associated with a risk of postoperative ...

A non cirrhotic patient with esophageal varices and portal vein thrombosis had recurrent variceal bleeding unsuccessfully controlled by endoscopy and esophageal transection. Emergency transhepatic portography confirmed the thrombosed right branch of the portal vein, while the left branch appeared angulated, shifted and stenotic. A stent was successfully implanted into the ...
