Veno-venous bypass (VVB) using a patent para-umbilical vein during liver transplantation (LT) has not been reported previously. Here, we report the decompression of the porto-mesenteric compartment via a patent para-umbilical vein in a patient needing a VVB during LT. Pre-transplant CT-scan showed a large patent para-umbilical vein. A femoro-axillary percutaneous VVB was installed prior to abdominal opening to decompress massive collateral veins in the abdominal wall. The para-umbilical vein was stapled and its proximal end was cannulated and connected to the VVB. The severe atrophy of the native liver allowed to place the whole liver graft in the "liver fossa" while maintaining the native liver pulled toward the left side and connected to the VVB. This maneuver maintained splanchnic venous decompression during latero-lateral cavo-caval anastomosis. The "portal" cannula was clamped and removed. The native portal vein was clamped and divided. Standard portal, arterial, and biliary reconstructions were then performed. A patent para-umbilical vein, present in one third of patients with portal hypertension could be used whenever VVB is indicated during LT in this setting.

Successful Transcatheter Arterial Embolization of Abdominal Wall Hematoma from the Left Deep Circumflex Iliac Artery after Abdominal Paracentesis in a Patient with Liver Cirrhosis: Case Report and Literature Review.

The occurrence of an abdominal wall hematoma caused by abdominal paracentesis in patients with liver cirrhosis is rare. This paper presents a case of an abdominal wall hematoma caused by abdominal paracentesis in a 67-year-old woman with liver cirrhosis with a review of the relevant literature. Two days prior, the patient underwent abdominal paracentesis for symptom relief for refractory ascites at a local clinic.

At birth, the umbilical cord contains various types of thin vessels that are near and outside the umbilicus and separate from the umbilical arteries and vein. These vessels are regarded as the remnant "vitelline vessels" and are often called "umbilical vessels", although this terminology could lead to confusion with the true umbilical arteries and vein. No study has yet comprehensively examined these vessels using histological sections.

Purpose: Sinusoidal obstruction syndrome (SOS)/hepatic veno-occlusive disease (VOD) is a fatal complication after hematopoietic stem cell transplantation. We previously reported the usefulness of an ultrasonographical (US) scoring system, the Hokkaido US-based scoring system consisting of ten parameters (HokUS-10): (1) hepatomegaly in the left lobe and (2) right lobe, (3) dilatation of the main portal vein (PV), (4) hepatofugal flow in the main PV, (5) decreased velocity of the PV, (6) dilatation of the para-umbilical vein (PUV), (7) appearance of blood flow signal in the PUV, (8) gallbladder (GB) wall thickening, (9) ascites, and (10) increased resistive index of the hepatic artery, for the diagnosis of SOS/VOD. However, the reliability of this system among operators remains elusive.

Article Synopsis
- The study focused on identifying MDCT features related to esophageal varices (EVs) and esophageal variceal hemorrhage (EVH) in cirrhotic patients.
- The research evaluated MDCT results from 124 patients, correlating the presence and size of collateral veins with the risk of developing EV and EVH.
- Findings indicated that specific collateral veins, particularly the coronary, short gastric, and paraesophageal veins, were significant predictors of EV and EVH, leading to the development of predictive models based on imaging characteristics.
