Small bowel intussusception (SBI) in pediatric patients resolves spontaneously in the majority of cases. Pathologic small bowel intussusception with a lead point is rare in children. Ultrasound (US) is the preferred initial imaging study for the diagnosis of intussusception. We report a case of long-segment SBI and secondary bowel obstruction caused by a large hamartomatous polyp. This case emphasizes unique, atypical ultrasound findings that may be encountered in small bowel intussusception, with correlative radiographic, CT (computed tomography) and intra-operative findings...

For transplant surgeons, end-stage liver disease with portal venous thrombosis and a previous splenorenal shunt (SRS) is a significant challenge during liver transplantation. Thrombosis of the portal vein can be corrected by surgical interventions, such as portal venous thrombectomy or surgical removal of the thrombosed portal vein. Even also placement of a graft between the mesenteric vein and the graft portal vein can be performed. If these maneuvers fail, a renoportal anastomosis (RPA) can be performed to achieve adequate graft inflow...

BACKGROUND: Glycoprotein-A Repetitions Predominant protein (GARP or LRRC32) is present on among others human platelets and endothelial cells. Evidence for its involvement in thrombus formation was suggested by full knockout of GARP in zebrafish. OBJECTIVES: To evaluate the role of GARP in platelet physiology and in thrombus formation using platelet and endothelial conditional GARP knock out mice. METHODS: Platelet and endothelial specific GARP knockout mice were generated using the Cre-loxP recombination system...

In patients undergoing pancreaticoduodenectomy (PD), unrecognized hemodynamically significant celiac axis (CA) stenosis impairs hepatic arterial flow by suppressing the collateral pathways supplying arterial flow from the superior mesenteric artery and leads to serious hepatobiliary complications due to liver and biliary ischemia, with a high rate of mortality. CA stenosis is usually due to an extrinsic compression by a previously asymptomatic median arcuate ligament (MAL). MAL is diagnosed by computerized tomography in about 10% of the candidates for PD, but only half are found to be hemodynamically significant during the gastroduodenal artery clamping test with Doppler assessment, which is mandatory before any resection...

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...

A true isolated superior mesenteric artery (SMA) dissection is a rare occurrence. The increasing use of diagnostic imaging studies has resulted in this rare disease being more recognized. A 68-year-old Caucasian female presented with sharp upper abdominal pain. Computed tomography (CT) of the abdomen showed dissection with thrombosis in the proximal SMA. Conservative management with bowel rest, blood pressure control, and anticoagulation relieved her symptoms. Follow-up CT showed stable dissection. Physicians should consider the diagnosis of isolated spontaneous SMA dissection after excluding more common causes...

BACKGROUND: Non-occlusive mesenteric ischemia (NOMI) is ischemia of the mesentery that is caused by hypoperfusion or vasospasm without any thrombosis. NOMI is difficult to diagnose by physical examination alone. Although angiographic examination of the superior mesenteric artery (SMA) is the usual diagnostic method used, it is an invasive examination. Usually, a long range of the bowel becomes discontinuously necrotic in NOMI. Here, we report a rare case of NOMI localized in the transverse colon that was diagnosed by computed tomography (CT) angiography which is a minimally invasive examination...

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...

Diverticulitis primarily affects the sigmoid colon and is often complicated by intra-abdominal abscesses and fistulas. Rarely, however, mesenteric venous thrombosis has been known to occur. Optimal management is still unclear. We report the first case of polymicrobial sepsis resulting from diverticular pylephlebitis, managed successfully with bowel rest, antibiotics, and anticoagulation.

BACKGROUND: Thrombolytic therapy for acute thrombosis is limited by life-threatening side effects such as major bleeding and neurotoxicity. New treatment options with enhanced fibrinolytic potential are therefore required. Here, we report the development of a new thrombolytic molecule that exploits key features of thrombosis. We designed a recombinant microplasminogen modified to be activated by the prothrombotic serine-protease thrombin (HtPlg), fused to an activation-specific anti-glycoprotein IIb/IIIa single-chain antibody (SCE5), thereby hijacking the coagulation system to initiate thrombolysis...

The following is a case report of moderately differentiated tubular adenocarcinoma of the stomach with widespread thrombosis of the portal vein, for which chemotherapy proved effective. A 75-year-old man presented to the clinic with a new onset ofmalaise. The patient had anemia, elevation ofliver and biliary enzymes, and significantly elevated CA19-9 levels at 43,581 U/mL and CEA levels at 2,560 ng/mL. An upper endoscopy revealed a mass lesion extending from the fundus to the pylorus as well as to the duodenum along the smaller curvature of the stomach...

REVIEW
Karunakaravel Karuppasamy
The common diagnostic tools available to evaluate the porto-spleno-mesenteric venous (PSMV) system provide either good hemodynamic information with limited morphological details [e.g., ultrasonography (US)] or excellent tomographic display of the anatomy with limited information about flow patterns [e.g., multidetector computed tomography (MDCT) and magnetic resonance imaging]. Although catheter-directed selective digital subtraction angiography (DSA) can provide excellent information about flow at a high temporal resolution and can generate images at a high spatial resolution, this technique is often limited by a lack of cross-sectional detail...

Isolated arterial dissection without aortic pathology has been rarely reported in mesenteric vessels. The natural history and appropriate treatment for this disease is uncertain because of the scarcity of literature which limits the data available to the clinician, resulting in management challenges. Herein, we report a rare case of a 42-year-old Tunisian man with spontaneous dissection and aneurysmal dilatation of the Celiac Artery (CA) and the Superior Mesenteric Artery (SMA) with partial thrombosis. This case was successfully managed conservatively with heparin infusion and blood pressure control and the patient remained symptom free at 15 months follow up...

Portal vein thrombosis (PVT) in a setting of liver metastasis is not easy to treat as it may be portal vein tumor thrombus (PVTT). A 77-year-old male patient was diagnosed as ascending colon carcinoma, underwent right hemicolectomy in 1991 with a recurrence in July 2009. In August 2009, he underwent computed tomography (CT) scan of the abdomen which showed evidence of superior mesenteric vein thrombosis with no liver metastasis. He was started with anticoagulation and decision was to treat long term. He was admitted with mesenteric artery ischemic symptoms in February 2012 on anticoagulation...
