Thrombosis of pancreatic arteriovenous malformation induced by diagnostic angiography: case report

BackgroundWe report on a case of pancreatic arteriovenous malformation (PAVM) that obliterated shortly after diagnostic angiography (DSA). PAVM is a rare anomaly that presents with upper abdominal pain, signs of acute pancreatitis and massive gastrointestinal bleeding. The management of PAVM is rather complex, with complete treatment usually accomplished only by a total extirpation of the affected organ or at least its involved portion. DSA prior to treatment decisions is helpful for characterizing symptomatic PAVM, since it can clearly depict the related vascular networks. In addition, interventional therapy can be performed immediately after diagnosis.Case presentationA 39-old male was admitted due to recurring upper abdominal pain that lasted several weeks. Initial examination revealed the absence of fever or jaundice, and the laboratory tests, including that for pancreatic enzymes, were unremarkable. An abdominal ultrasound (US) showed morphological and Doppler anomalies in the pancreas that were consistent with a vascular formation. A subsequent DSA depicted a medium-sized nidus, receiving blood supply from multiple origins but with no dominant artery. Coil embolization was not possible due to the small caliber of the feeding vessels. In addition, sclerotherapy was not performed so as to avoid an unnecessary wash out to the non-targeted duodenum. Consequently, the patient received no specific treatment for his symptomatic PAVM. A large increase in pancreatic enzymes was noticed shortly after the DSA procedure. Imaging follow-up by means of CT and MRI showed small amounts of peripancreatic fluid along with a limited area of intra-parenchymal necrosis, indicating necrotizing pancreatitis. In the post-angiography follow-up the patient was hemodynamically stable the entire time and was treated conservatively. The symptoms of pancreatitis improved over a few days, and the laboratory findings returned to normal ranges. Long-term follow-up by way of a contrast-enhanced CT revealed no recanalization of the thrombosed PAVM.ConclusionThe factors associated with the obliteration of PAVM during or after DSA are poorly understood. In our case it may be attributed to the low flow dynamics of PAVM, as well as to the local administration of a contrast agent. Asymptomatic PAVM, as diagnosed with non-invasive imaging techniques, should not be evaluated with DSA due to the potential risk of severe complications, such as acute pancreatitis.

Successful Treatment of Pancreatic Arteriovenous Malformation with External Beam Radiotherapy

Pancreatic arteriovenous malformation (AVM) is a rare disease that occurs worldwide, but only a few sporadic cases have been reported in Taiwan. The poor definition of pancreatic AVM has been the major obstacle in its diagnosis. Conventionally, angiography and CT scans are used to diagnose pancreatic AVM. Here we report a case of pancreatic AVM that was initially disclosed by endoscopic ultrasound (EUS) and confirmed by angiography. In this case report, we will also present the very good response of pancreatic AVM to external beam radiotherapy.

Pancreatic Arteriovenous Malformation as an Unusual Cause of Chronic Gastrointestinal Bleeding in a Patient with Early Gastric Cancer: Multimodality Imaging Spectrum with Pathologic Correlation

Anemia is one of the most common causes of dizziness. Most chronic anemia is associated with gastrointestinal bleeding, such as peptic ulcers or cancer of various organs (1). Pancreatic arteriovenous malformation (AVM) is a rare cause of gastrointestinal bleeding (2). They are usually asymptomatic but may present with abdominal pain, portal hypertension in the absence of hepatopathy, or gastrointestinal bleeding. Although pancreatic AVM is rare, it should be considered in patients with anemia of unknown origin or those who failed therapy for more common causes of anemia. Even though previous studies have reported the imaging findings of pancreatic AVM including ultrasound, computed tomography, and magnetic resonance imaging, most Arteriovenous malformation (AVM) of the pancreas is extremely rare, although it may be increasingly diagnosed due to the widespread use of cross-sectional imaging of the abdomen. Early diagnosis of this disease is important to prevent delay of treatment and resulting fatal complications. We report a rare case of pancreatic AVM in a 48-year-old man who presented with severe chronic anemia and early gastric cancer, which made diagnosis challenging. Imaging findings, including ultrasound, computed tomography, and magnetic resonance imaging, are shown, as well as the pathologic features.

"Solid-looking" and "true" solid serous cystadenoma of the pancreas: A challenging diagnosis at imaging.

s / Pancreatology 14 (2014) S1eS129 S88 overall pancreatic arteriovenous malformation were bleeding (50.6%), pancreatitis (16.9%), portal hypertension (6.7%), and pseudocyst (3.4%). The most common presenting symptom of pancreatic arteriovenous malformation was gastrointestinal bleeding (47.2%), followed by epigastric pain (46.1%). Surgery (43.8%) was the most common treatment for pancreatic arteriovenous malformation cases, followed by transarterial embolization (11.2%), a combination of surgery and transarterial embolization (10.1%), and radiotherapy (2.2%). No intervention was done for 29.2% of the cases of pancreatic arteriovenous malformation. Conclusion: Pancreatic arteriovenous malformation occurs most commonly in the pancreatic head; gastrointestinal bleeding is the main symptom. Surgical resection of the pancreatic arteriovenous malformation is recommended whenever feasible.

Pancreatic Arteriovenous Malformation

BackgroundPancreatic arteriovenous malformation is very rare, but may cause significant clinical symptoms such as catastrophic bleeding. Herein, we discuss the clinical presentation and management of patients pancreatic arteriovenous malformations. MethodsThe data pool for the analysis was collected from pancreatic arteriovenous malformation cases encountered by our institution and sporadic case reports in the English literature. ResultsA total of 89 cases of pancreatic arteriovenous malformation were collected for this study, including 59 cases of arteriovenous malformation in the pancreatic head (62.3 %) and 30 in the pancreatic body-tail (33.7 %). The most commonly associated complications for overall cases of pancreatic arteriovenous malformation were bleeding (50.6 %), pancreatitis (16.9 %), portal hypertension (6.7 %), and pseudocyst (3.4 %). The most common presenting symptom of pancreatic arteriovenous malformation was gastrointestinal bleeding (47.2 %), followed by epigastric pain (46.1 %). Surgery (43.8 %) was the most common treatment for pancreatic arteriovenous malformation cases, followed by transarterial embolization (11.2 %), a combination of surgery and transarterial embolization (10.1 %), and radiotherapy (2.2 %). No intervention was done for 29.2 % of the cases of pancreatic arteriovenous malformation. ConclusionsPancreatic arteriovenous malformation occurs most commonly in the pancreatic head; gastrointestinal bleeding is the main symptom. Surgical resection or transarterial embolization appears to be indicated in patients with symptomatic pancreatic arteriovenous malformation.

A Case of Pancreatic Arteriovenous Malformation Associated With Duodenal Ulcer

Pancreatic arteriovenous malformation is a very rare disease. We report a case of pancreatic arteriovenous malformation associated with duodenal ulcer on the bulbus of the duodenum causing massive intestinal bleeding. A 66-year-old male was admitted to our hospital complaining of epigastralgia and tarry stool. Endoscopic examination revealed duodenal ulcer with continuous bleeding and endoscopic clipping was performed. Abdominal ultrasonographic examination revealed a hypoechoic mass in the head of the pancreas. Color Doppler abdominal ultrasonographic examination revealed a mosaic-like color signal in the hypoechoic mass. Abdominal angiography showed racemose vascular network in the head of the pancreas. Because epigastric discomfort and tarry stool were increased, emergency pylorus preserving pancreatoduodenectomy was performed. Histologically, there were numerous vascular structures with dilated and tortuous vessels at the pancreas head, and the adjacent duodenal wall was destroyed by pancreatic arteriovenous malformation.

The MDCT and MRI Findings of a Pancreatic Arteriovenous Malformation Combined with Isolated Dissection of the Superior Mesenteric Artery: A Case Report

Pancreatic arteriovenous malformation and isolated spontaneous dissection of the superior mesenteric artery are both rare maladies, and now they can be easily diagnosed due to the development of such noninvasive modalities as multi-detector computed tomography and magnetic resonance imaging. We report here on the multi-detector computed tomography and magnetic resonance imaging findings of a rare case of pancreatic arteriovenous malformation combined with isolated dissection of the superior mesenteric artery.

Pancreatic arteriovenous malformation with portal hypertension

A 45-year-old man with recurrent episodes of hematemesis caused by extensive varices in the esophagus and stomach was admitted. He had a history of liver cirrhosis with hepatitis C virus infection. Computed tomography revealed a conglomeration of small strong nodular stains in the pancreatic head. Angiography revealed a racemose vascular network at the same site and early appearance of the portal venous system in the arterial phase. With a diagnosis of pancreatic arteriovenous malformation with portal hypertension, he underwent pylorus-preserving pancreaticoduodenectomy, preceded, 2 days earlier, by transcatheter arterial embolization of some of the feeding arteries. The varices observed preoperatively in the esophagus and stomach disappeared, and he has been well for 6 years after the operation. We reviewed 47 cases of pancreatic arteriovenous malformation previously reported in the English-language literature, with a focus on the clinical manifestations, treatment approaches, and etiological relationship with portal hypertension and liver cirrhosis.

Color Doppler Ultrasonography of a Pancreatic Arteriovenous Malformation

A pancreatic arteriovenous malformation (AVM) is a rare disease entity that has been estimated to account for 4% to 5% of all AVMs in digestive organs, and, to our knowledge, only 53 cases have been reported in the radiologic literature. 1 - 1 3 Although color Doppler ultrasonography may be very valuable in the diagnosis of disease, we found only 10 reported cases of pancreatic AVMs that had been evaluated by this imaging technique. 2 , 3 , 6 , 1 0 This report describes characteristic color Doppler findings that are useful in the diagnosis of a pancreatic AVM.

A Case of Pancreatic Arteriovenous Malformation with Portal Hypertension: Treatment with Transjugular Intrahepatic Portosystemic Shunt

Arteriovenous malformation of the pancreas is a rare disease, and it is manifested by gastrointestinal bleeding and/or portal hypertension. Surgery is definitely the treatment of choice at the early stage of the disease, and a transcatheter embolization is an alternative treatment for the control of bleeding and if the lesion is surgically inaccessible. We describe a 62-year-old man who had refractory ascites and esophageal variceal bleeding caused by a pancreatic arteriovenous malformation associated with portal hypertension; this was successfully treated by a transjugular intrahepatic portosytemic shunt.
