Vascular thrombosis is a major complication after pancreas transplantation. Because delays in detecting thrombosis often result in graft failure, monitoring blood flow is crucial. Periodic evaluation using color Doppler ultrasonography is mostly performed for monitoring blood flow in the grafted pancreas. However, conventional color Doppler imaging has limited capability to visualize low-velocity blood flow. Superb microvascular imaging (SMI) is a novel ultrasound Doppler technique that is especially sensitive in detecting low-velocity flow...

Despite systemic thromboembolic complications being frequent, portal vein thrombosis is a rare complication of nephrotic syndrome. We report here a liver transplant recipient who presented a late extensive portal vein thrombosis related to nephrotic syndrome. During regular follow-up after liver transplant, the patient presented with diabetes, arterial hypertension, hypercholesterolemia, and progressive renal dysfunction. In addition, urine analysis showed isolated proteinuria, and the diagnosis of nephrotic syndrome was made 36 months after liver transplant...

AIM: To investigate wall shear stress (WSS) magnitude and distribution in cirrhotic patients with portal hypertension using computational fluid dynamics. METHODS: Idealized portal vein (PV) system models were reconstructed with different angles of the PV-splenic vein (SV) and superior mesenteric vein (SMV)-SV. Patient-specific models were created according to enhanced computed tomography images. WSS was simulated by using a finite-element analyzer, regarding the blood as a Newtonian fluid and the vessel as a rigid wall...

Portomesenteric venous thrombosis is a rare complication reported in only a few cases involving laparoscopic bariatric surgery. We report a case of a 44-year-old woman who presented 14 days after recent laparoscopic sleeve gastrectomy with the chief complaint of abdominal pain and associated nausea. Abdominal CT demonstrated thrombi in her superior mesenteric, portal and splenic veins. She was initiated on therapeutic heparin but developed haemorrhagic shock shortly afterwards. Subsequent CT angiogram failed to localise the source of her haemorrhage...

Idiopathic non-cirrhotic portal hypertension (INCPH) is portal hypertension (PHT) without cirrhosis and other identifiable causes. Esophageal and gastric varices are seen in INCPH which are mostly asymptomatic. We present a rare case of symptomatic isolated gastric varices (IGV) in the setting of INCPH. We report a case of a 60-year-old man who presented with an acute onset of hematemesis and no identifiable history. Upon further evaluation, he was found to have non-bleeding dilated gastric varices on esophagogastroduodenoscopy (EGD) and PHT without cirrhosis...

Gastrointestinal bleeding following Roux-en- Y gastric bypass (RYGB) is rare. We report an unusual cause of upper gastrointestinal bleeding following RYGB that was complicated by porto- splenic vein thrombosis. A 35- year- old woman was successfully treated by mesocaval surgical shunt for recurrent variceal hemorrhage in the excluded stomach following RYGB.

In Asian countries, concomitant splenectomy in living donor liver transplantation (LDLT) is indicated to modulate the portal vein pressure in the small sized graft to protect against small for size syndrome. While concomitant splenectomy in deceased donor liver transplantation is almost contraindicated based on western reports of increased mortality and morbidity rate due to septic complications, there are few studies about that in LDLT. So, we retrospectively investigated the clinical outcome of adult LDLT at Kyoto University Hospital from July 2010 to July 2016...

Patients with large spontaneous splenorenal shunts (SRSs) prove challenging during liver transplantation (LT), regardless of organizing portal vein (PV) thrombosis. Here, we detail the clinical outcomes of 26 patients who underwent direct ligation of large SRSs during LT. Direct ligation of large SRS was applied in poor portal flow during LT. We performed temporary test clamping of the SRS before direct ligation and applied PV pressure monitoring in patients who showed signs of portal hypertension, such as bowel edema...

Upper gastrointestinal bleeding (UGIB) represents one of the most serious conditions of the gastrointestinal tract with a mortality rate of 10%. The main cause of UGIB is peptic ulcer, accounting for 28%-59% of cases. A rare cause of UGIB is submucosal arterial collaterals, which develop after splenic artery thrombosis. UGIB secondary to gastric submucosal collateral arteries should be considered in patients with endoscopic appearance of varicose veins in the absence of portal hypertension. Computed tomography angiography (CTA) is the only fast and noninvasive definitive imaging technique for such patients...

Torsion of a wandering spleen is a rare disease. The symptoms and signs of this condition are only present when the splenic pedicle torts. The etiological factors are the congenital absence of the ligaments that hold the spleen in its normal anatomic position, or the relaxation of these ligaments resulting from conditions like trauma and abdominal surgery. We aimed to present a rare case with torsion of wandering spleen that consequently developed thrombosis of portal vein and its branches, taking into consideration the relevant literature...

Deep abdominal vein thrombosis is extremely rare among thrombotic events secondary to the use of contraceptives. A case to illustrate the clinical utility of ethno-specific pharmacogenetic testing in warfarin management of a Hispanic patient is reported. A 37-year-old Hispanic Puerto Rican, non-gravid female with past medical history of abnormal uterine bleeding on hormonal contraceptive therapy was evaluated for abdominal pain. Physical exam was remarkable for unspecific diffuse abdominal tenderness, and general initial laboratory results-including coagulation parameters-were unremarkable...

Protein C deficiency is a risk of venous thrombosis because of poor fibrinolytic activity. It remains controversial whether protein C deficiency causes arterial thrombosis. A 21-year-old woman was referred with a chief complaint of right leg pain and numbness. Contrast-enhanced computed tomography revealed a low-density mass in the left ventricle (LV), splenic infarction, and peripheral arterial obstructions in her right leg. Thrombosis extending from the renal vein to the inferior vena cava was also detected...

This case describes a 46-year-old male recipient of a kidney-pancreas transplant who is Jehovah's Witness. Early in the postoperative period, he was found to have splenic vein thrombosis requiring heparin infusion. Two days later, he developed severe symptomatic anemia (hemoglobin <6 g/dL). Standard medical therapy for bloodless surgical patients with severe anemia was instituted. Nevertheless, the patient's hemoglobin concentration continued to decline to critical levels (2 g/dL). Because he was Jehovah's Witness, transfusion of allogeneic blood products was not an option, prompting use of a hemoglobin-based oxygen carrier (HBOC)...

We encountered a patient with hepatocellular carcinoma who had discrepant imaging findings on portal vein thrombosis with portal phase dynamic computed tomography (CT) and CT during arterial portography (CTAP). CTAP, via the superior mesenteric artery and via the splenic artery, both showed a portal perfusion defect in the right hepatic lobe, indicating portal vein thrombosis in the main trunk of the right portal vein. Portal phase dynamic CT clearly depicted portal perfusion of the same hepatic area. Transarterial chemoembolization was successfully performed, but it was associated with severe liver injury...
