RATIONALE: Portal vein thrombosis is a complication after liver transplantation and cavernous transformation of the portal vein (CTPV) is a result of portal vein thrombosis, with symptoms of portal hypertension revealed by an enhanced CT scan. Meso-Rex bypass is an artificial shunt connecting the left portal vein to the superior mesenteric vein and is mainly used for idiopathic cavernomas. This technique is also used for post-transplant portal vein thrombosis in pediatric patients thereby bypassing obstructed sites of the extrahepatic portal vein...

Background -Platelets from patients with diabetes are hyperactive. Hyperactivated platelets may contribute to cardiovascular complications and inadequate responses to antiplatelet agents in the setting of diabetes. However, the underlying mechanism of hyperactivated platelets is not completely understood. Methods -We measured P2Y12 expression on platelets from patients with type 2 diabetes mellitus (T2DM) and on platelets from rats with diabetes. We also assayed platelet P2Y12 activation by measuring cAMP and VASP phosphorylation...

Pylephlebitis or infective suppurative thrombosis of the portal mesenteric venous system is an uncommon condition that can potentially be deadly if not recognized and treated early. Although most commonly associated with pancreatitis and diverticulitis, any intra-abdominal or pelvic infection occurring in the region drained by the portal venous system can cause this rare entity. We report a case of a 75-year-old woman who developed post polypectomy pylephlebitis following colonoscopy, a condition rarely reported in the literature...

Thrombosis is a frequent cause of morbidity and mortality in patients with nephrotic syndrome (NS). Though venous thromboses are common in NS, arterial thromboses are relatively rare. Commonly involved arteries include coronary, iliac, femoral, renal, cerebral, pulmonary, mesenteric, and axillary arteries, and the aorta. Arterial thromboses are associated with poor prognosis; treatment options are limited and patients may not always be amenable to treatment. We present the case of a 39-year-old female with NS who presented with thigh pain and was found to have sub-acute popliteal artery thrombosis...

Surgical resection represents the mainstay treatment and only potentially curative option for gastric carcinoma, and is increasingly performed laparoscopically. Furthermore, other tumours and selected cases of non-malignant disorders of the stomach may require partial or total gastrectomy. Often performed in elderly patients, gastric resection remains a challenging procedure, with significant morbidity (14-43% complication rate) and non-negligible postoperative mortality (approximately 3%). This paper provides an overview of contemporary surgical techniques for non-bariatric gastric resection, reviews and illustrates the expected postoperative imaging appearances, common and unusual complications after partial and total gastrectomy...

OBJECTIVES: We previously performed the frozen elephant trunk (FET) technique for acute type A aortic dissection to try to improve the long-term prognosis. In this study, we report the mid-term results of the FET technique for treating retrograde type A acute aortic dissection using a new device, the J Graft open stent graft (JOSG). METHODS: Between January 2008 and December 2015, 24 patients (mean age: 59.3 ± 13.9 years) underwent total arch replacement with the FET technique using the JOSG for retrograde type A acute aortic dissection...

Splenoportal axis thrombosis not associated with cirrhosis or neoplasms has a prevalence lower than 5 per 10,000 people. An etiologic factor responsible for portal thrombosis is finally identified in most cases, usually systemic thrombogenic factors or predisposing local factors. However, despite a detailed study of all etiologic factors, up to 30% of cases are eventually considered as idiopathic in origin. We report the case of a 41-year-old patient who presented with abdominal pain and lower extremity edema...

OBJECTIVE: Currently prescribed antiplatelet drugs have 1 common side effect-an increased risk of hemorrhage and thrombocytopenia. On the contrary, bleeding defects associated with glycoprotein VI (GPVI) expression deficiency are usually slightly prolonged bleeding times. However, GPVI antagonists are lacking in clinic. APPROACH AND RESULTS: Using reverse-phase high-performance liquid chromatography and sequencing, we revealed the partial sequence of trowaglerix α subunit, a potent specific GPVI-targeting snaclec (snake venom C-type lectin protein)...

Several CGHC motif-containing disulfide isomerases support thrombosis. We here report that ERp72, with three CGHC redox-active sites (a(o), a, and a'), supports thrombosis. We generated a new conditional knockout mouse model, and found that Tie2-Cre/ERp72(fl/fl) mice with blood and endothelial cells lacking ERp72 had prolonged tail bleeding times, and decreased platelet accumulation in laser-induced cremaster arteriole injury and FeCl3-induced mesenteric arterial injury. Fibrin deposition was decreased in the laser injury model...

Pancreatic head resection for chronic pancreatitis is a challenging procedure, in the presence of venous collaterals, cavernous transformation, extensive fibrosis or porto-mesenteric stenosis or thrombosis. We present a surgically treated patient for the intractable pain of chronic pancreatitis. Complications with biliary obstruction and portal vein stenosis/thrombosis resulted in cavernous transformation. A pancreaticoduodenectomy combined with portal vein resection was intended in a 51 year-old male, but the procedure was terminated due to the high risk associated with intraoperative bleeding...

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...

Intestinal transplantation (ITx) is indicated in patients with irreversible intestinal failure (IF) and life-threatening complications related to total parenteral nutrition (TPN). ITx can be classified into three main types. Isolated intestinal transplantation (IITx), that is, transplantation of the jejunoileum, is indicated in patients with preserved liver function. Combined liver-intestine transplantation (L-ITx), that is, transplantation of the liver and the jejunoileum, is indicated in patients with liver failure related to TPN...

AIM: To determine the true prevalence of thrombocytosis in children less than 2 years of age with bronchiolitis, its association with risk factors, disease severity and thromboembolic complications. METHODS: A retrospective observational medical chart review of 305 infants aged two years or less hospitalized for bronchiolitis. Clinical outcomes included disease severity, duration of hospital stay, admission to pediatric intensive care unit, or death. They also included complications of thrombocytosis, including thromboembolic complications such as cerebrovascular accident, acute coronary syndrome, deep venous thrombosis, pulmonary embolus, mesenteric thrombosis and arterial thrombosis and also hemorrhagic complications such as bleeding (spontaneous hemorrhage in the skin, mucous membranes, gastrointestinal, respiratory, or genitourinary tracts)...

Portal vein thrombosis (PVT) is frequent in patients with liver cirrhosis and possible severe complications such as mesenteric ischemia are rare, but can be life-threatening. However, different aspects of clinical relevance, diagnosis and management of PVT are still areas of uncertainty and investigation in international guidelines. In this article, we elaborate on PVT classification, geographical differences in clinical presentation and standards of diagnosis, and briefly on the current pathophysiological understanding and risk factors...

Standard hormone therapy for menopausal women [conjugated equine estrogen (CEE) 0.625 mg] has been associated with increased risk of venous thrombosis. Regimens containing a lower CEE dose (0.30 mg) have been used clinically to decrease side effects of supraphysiologic doses of estrogen. In this study, we determined the effects of standard (SD) and low dose (LD) of CEE on venular function in ovariectomized (OVX) spontaneously hypertensive rats (SHR). Contractions by angiotensin-II (Ang-II 10 μM) in perfused mesenteric venular bed were markedly increased in OVX (21...

Portal Vein Thrombosis (PVT) is caused by various thrombophilic states. PVT secondary to underlying vasculitis especially Churg-Strauss disease is among the rarest presentation. Here, we report a case of peripheral eosinophilia, eosinophilic ascitis and venous thrombosis involving portal vein and superior mesenteric vein diagnosed as Churg-Strauss Syndrome (CSS). He was managed with steroids and anticoagulants. Following initiation of steroids, eosinophilia and eosinophilic ascitis improved.

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...
