Pancreatic Arteriovenous Malformation Presenting with Upper Gastrointestinal Bleeding: Treatment with Transarterial Embolization—A Case Report

AbstractPancreatic arteriovenous malformations (AVMs) are a rare entity among visceral AVMs and less common cause of gastrointestinal bleeding. We report a case of pancreatic AVM in a 45-year-old man who presented with upper gastrointestinal bleeding and duodenal ulcers, and was hemodynamically unstable. Ultrasound and computed tomography (CT) of the abdomen showed multiple dilated arterial channels in the head region of the pancreas, arising from the gastroduodenal artery, with early filling of the portal vein, suggestive of an AVM. Transarterial embolization was performed by selectively embolizing the arterial feeders using poly-vinyl alcohol (PVA) particles. Postembolization, obliteration of the AVM was seen. On follow-up 2 months later, the patient was clinically stable.

Successful Surgical Resection of Pancreatic Arteriovenous Malformation Complicated by Acute Pancreatitis: A Case Report.

A 73-year-old man presented with left hypochondral pain. Dynamic computed tomography (CT) revealed abnormal vessels surrounding the pancreas, leading to a suspected diagnosis of pancreatic arteriovenous malformation (PAVM). At the time of the initial examination, dynamic CT revealed mild acute pancreatitis, and PAVM was diagnosed based on the findings of dynamic CT. Although repeated abdominal pain was observed after the improvement of pancreatitis, distal pancreatectomy was performed. At >1 year after surgery, no recurrence of PAVM was observed. Surgical resection should be considered in patients with symptomatic PAVM.

An Update of Treatment of Pancreatic Arteriovenous Malformations.

Pancreatic arteriovenous malformation is a rare entity (0.9%). There are about 200 articles available in PubMed. This review article includes 86 published articles, with 117 cases published after 2000. The median age at diagnosis was 51, and most of the patients were male (87.0%). The symptoms included pain, bleeding, pancreatitis, ulcers in the duodenum or stomach, varix formation, jaundice, and ascites. The diagnostic modalities were angiography, contrast-enhanced CT, MRI, and/or Ultra Sound. The most common treatments were surgery and embolization. The clinical success rate of embolization reported was 57.7%. The tailored embolization based on each agio-architecture had a clinical success rate of 80%. If embolic therapy is ineffective, surgical intervention should be considered.

Radiologic findings of arteriovenous malformation in pancreatic head

Arteriovenous malformations (AVMs) are clusters of abnormal arteries and vessels connected by one or more direct connections called fistula or shunt. AVM can occur in any part of the body. Pancreatic arteriovenous malformation (P-AVM) can be defined as an abnormal vascular network that develops from one or more feeding arteries, dilates early drainage vessels, and forms an arteriovenous shunt. In this paper, we wanted to represent a 45-year-old male patient admitted to our hospital due to abdominal pain with a case of AVM and a review of the literature.

Laparoscopic distal pancreatectomy for pancreatic arteriovenous malformation complicated with portal hypertension.

Pancreatic arteriovenous malformation (PAVM) is defined as a vascular anomaly with an abnormal anastomosis of the arterial and portal networks within the pancreas. Treatment modalities of PAVM include transarterial embolisation (TAE), irradiation and operation. Most patients treated with TAE alone will experience recurrence, so surgery is the best radical treatment. A female patient was admitted to our institution for the treatment of haematemesis. Examination revealed varices in the oesophagus and stomach, collateral circulation development caused by portal hypertension and PAVM of the pancreas. Surgical treatment was intended to reduce left portal hypertension. In this case, collateral circulation were considered dangerous points for unexpected bleeding. TAE was performed on the splenic artery before surgery to reduce blood flow in the areas with collateral circulation. En bloc resection of retroperitoneal tissue using the surgical procedure of radical antegrade modular pancreatosplenectomy was effective to minimise blood loss.

Arteriovenous malformation in pancreas mimicking hypervascular tumor.

Arteriovenous malformation (AVM) is defined as a disease that causes blood flow abnormality due to anastomoses of the arteries and veins. AVM can occur in any gastrointestinal tract, but pancreatic AVM (P‐AVM) is very rare. Previous reports demonstrated that contrast‐enhanced CT (CECT) typically showed abnormal vascular network in pancreas. We present a 58‐year old man with a history of acute pancreatitis. He was referred to our hospital for examination of pancreatic mass. CECT showed a round‐shaped hypervascular lesion with a diameter of 8 mm in the head of the pancreas. Selective angiography showed vascular network and early visualization of superior mesenteric vein. We finally diagnosed this case as P‐AVM. He underwent duodenum preserving pancreatic head resection. Histological findings confirmed the preoperative diagnosis of P‐AVM.

A case of duodenal hemorrhage due to arteriovenous malformation around a serous cystic neoplasm

BackgroundNo reports have so far described arteriovenous malformation (AVM) in the pancreas caused by a tumor. We herein report a case of pancreatoduodenectomy for a patient who developed duodenal hemorrhage due to AVM developed around serous cystic neoplasm (SCN) of the pancreas.Case presentationA 79-year-old man was referred to our hospital because of anemia (Hb 7.4 g/dl) and pancreatic head tumor. Computed tomography showed microcystic-type SCN, 87 mm in size, in the pancreatic head. Vascular hyperplasia had developed around the cystic lesion. Upper gastrointestinal endoscopy and colonoscopy did not reveal the cause of anemia, so the patient was followed closely without hemostatic therapy. Iron preparations had improved the anemia. Three months later, the patient developed anemia (Hb 5.8 g/dl) again. Gastrointestinal endoscopy showed oozing from the mucosa in the duodenum via the swollen vascular hyperplasia. He was diagnosed as duodenal hemorrhage from the blood vessels around SCN. Pancreatoduodenectomy was performed to control repeated duodenal bleeding. A histopathological examination revealed that the cystic lesion in the pancreatic head was SCN, and the AVM developed around SCN and duodenum, causing repeated duodenal hemorrhage. The patient was discharged on postoperative day 22. Nine months after surgery, the patient had no recurrence of anemia.ConclusionsThere have been no reports of duodenal hemorrhage due to acquired pancreatic AVM around pancreatic tumor, including SCN. We successfully treated a case of duodenal hemorrhage due to pancreatic AVM around SCN by pancreatoduodenectomy.
