Splenic vein thrombosis is a relatively common finding in pancreatitis. Gastric variceal bleeding is a life-threatening complication of splenic vein thrombosis, resulting from increased blood flow to short gastric vein. Traditionally, splenectomy is considered the treatment of choice. However, surgery in necrotizing pancreatitis is dangerous, because of severe inflammation, adhesion, and bleeding tendency. In the Warshaw operation, gastric variceal bleeding is rare, even though splenic vein is resected. Because the splenic artery is also resected, blood flow to short gastric vein is not increased problematically...

PURPOSE: To evaluate safety of resin microsphere radioembolization (RE) without prophylactic embolization of the gastroduodenal artery (GDA). MATERIALS AND METHODS: Between July 2013 and April 2015, all patients undergoing RE with resin microspheres for liver-dominant metastatic disease were treated without routine embolization of the GDA. Selective embolization of distal hepaticoenteric vessels was performed if identified by digital subtraction angiography, cone-beam computed tomography, or technetium-99m macroaggregated albumin scintigraphy...

Portal hypertension commonly arises in the setting of advanced liver cirrhosis and is the consequence of increased resistance within the portal vasculature. Less commonly, left-sided noncirrhotic portal hypertension can develop in a patient secondary to isolated obstruction of the splenic vein. We present a rare case of left-sided portal hypertension and isolated gastric varices in a patient with large B-cell lymphoma, who was treated with splenic artery embolization. The patient is a 73-year-old male with no previous history of liver disease, who presented with coffee ground emesis and melena...

A 43-year-old female with history of systemic lupus erythematosus, prior cytomegalovirus esophagitis treated with ganciclovir, and long segment Barrett's esophagus (Prague class C8 M9) with high grade dysplasia treated with radiofrequency ablation presented to the hospital with hematemesis. An upper gastrointestinal endoscopy showed multiple esophageal ulcers with active arterial spurting which could not be controlled with endoscopic interventions including placement of hemostatic clips. An emergent angiogram demonstrated actively bleeding saccular dilations (pseudoaneurysms) in the esophageal branches of the lower thoracic aorta as well as left gastric artery for which gelfoam and coil embolization was initially successful...

INTRODUCTION: Arterial pseudoaneurysm is a rare and life-threatening complication of pancreatitis, seen more often in chronic than in acute pancreatitis. It involves mostly the splenic artery, while only in 10% of the case it appears in pancreaticoduodenal and gastric artery. This case report described an asymptomatic pseudoaneurysm of the posterior superior pancreaticoduodenal artery and of the right gastric artery, which occurred after 13days from the episode of acute pancreatitis and, then it was treated with vascular angioembolization...

Epigastric pain is a common symptom in the emergency department. Most epigastric pain is not fatal, except in acute myocardial infarction, aortic dissection, and abdominal aneurysm rupture. Epigastric pain can also be the only symptom of isolated spontaneous gastric artery dissection. We report the case of a 51-year-old woman diagnosed with neurofibromatosis who initially presented with only epigastric pain. She was initially misdiagnosed with gastritis, treated conservatively, and discharged. Two hours later, she returned to the emergency department with persistent epigastric pain and rebound tenderness in the epigastric area...

Segmental arterial mediolysis (SAM) is a rare, nonarteriosclerotic, noninflammatory vascular disease and mostly affects medium-to-large sized abdominal arteries as well as presents with hemorrhages in the abdominal cavity. We report the case of a patient with SAM of the celiac, right renal, jejunal branch of the superior mesenteric, left gastric, and splenic arteries who was diagnosed by excluding other causes and in whom transcatheter embolization was performed in two different sessions, but he died because of an undefined reason...

Splenosis, the autotransplantation of splenic tissue following splenic trauma, is uncommonly clinically significant. Splenosis is typically diagnosed incidentally on imaging or at laparotomy and has been mistakenly attributed to various malignancies and pathological conditions. On the rare occasion when splenosis plays a causative role in a pathological condition, a diagnostic challenge may ensue that can lead to a delay in both diagnosis and treatment. The following case report describes a patient presenting with a massive upper gastrointestinal bleed resulting from arterial enlargement within the gastric fundus secondary to perigastric splenosis...

Laparoscopic surgery for the treatment of a ruptured visceral artery aneurysm is recognized as a challenging procedure. Here, we describe our experience with laparoscopic surgery to treat a ruptured aneurysm of the right gastric artery. A 72-year-old woman was diagnosed with intra-abdominal hemorrhage caused by a ruptured aneurysm of the right gastric artery. Transcatheter arterial embolization failed because the right gastric artery could not be cannulated. Therefore, we performed laparoscopic surgery. Using laparoscopy, we detected that the bleeding from the aneurysm had ceased; thus, the planned procedure was successful...

We are reporting the rare case of splenic artery aneurysm of 4 cm of diameter presenting as a sub mucosal lesion on gastro-duodenal endoscopy. This aneurysm was treated by endovascular coil embolization and stent graft implantation. The procedure was uneventful. On day 1, the patient presented an acute severe epigastric pain and cardiovascular arrest. Abdominal computed tomography scan showed an active leak of the intravenous contrast dye in the peritoneum from the splenic aneurysm. We performed an emergent resection of the aneurysm, and peritoneal lavage...

: In (90)Y radioembolization, nontarget embolization to the stomach or small bowel can result in gastrointestinal injury, a rare but difficult to manage clinical complication. However, dosimetric thresholds for toxicity to these tissues from radioembolization have never been evaluated in a controlled setting. We performed an analysis of the effect of (90)Y radioembolization in a porcine model at different absorbed-dose endpoints. METHODS: Six female pigs underwent transfemoral angiography and infusion of (90)Y-resin microspheres into arteries supplying part of the gastric wall...

We report a case of Chronic lymphocytic leukemia (CLL) with associated hypersplenism, that was referred to us for partial splenic embolization (PSE) as the patient was not a surgical candidate for splenectomy. Initially, we were not successful in catheterizing the splenic artery from the celiac trunk due to significant atherosclerotic disease. Therefore, we successfully managed to access the distal splenic artery through patent gastro-epiploic collateral circulation along the greater curvature of the stomach...

The vessels that communicate between the liver and adjacent structures require bridges between them. The bridges comprise the ligaments of the liver as follows: the falciform ligament, right and left coronary ligaments, lesser omentum including the hepatogastric ligament and hepatoduodenal ligament. Each ligament has specific communications between the intrahepatic and extrahapetic vessels. The venous communications called as the portosystemic shunt would become apparent in patients with portal hypertension, intrahepatic portal vein thrombosis and superior vena cava syndrome...

Spontaneous mediastinal hematoma is exceedingly rare. We described such a case of a 61-year-old male with a posterior mediastinal hematoma from ruptured small aneurysm, which was ascertained via contrast-enhanced computed tomography examination. Subsequent super-selective angiography of left gastric artery revealed a ruptured aneurysm with contrast medium leakage, feeding vessels respectively from caudal and cranial artery. The left gastric artery branch caudally feeding aneurysm was successfully occluded, while cranially feeding artery from the branch of left bronchial artery failed to embolize due to complex anatomic factor...
