Insights

Pancreatic arteriovenous malformations (AVMs) are rare gastrointestinal conditions. Surgical intervention offers definitive management for symptomatic pancreatic AVMs, as demonstrated in this case report.

Area of Science:

  • Gastroenterology
  • Vascular Surgery
  • Radiology

Background:

  • Pancreatic arteriovenous malformations (AVMs) are rare vascular anomalies within the gastrointestinal tract.
  • Symptoms can include gastrointestinal bleeding, such as hematemesis and melena.

Purpose of the Study:

  • To present a case of pancreatic head AVM diagnosed and surgically managed.
  • To highlight the diagnostic imaging findings and treatment outcomes for pancreatic AVM.

Main Methods:

  • Computed tomography (CT) and magnetic resonance imaging (MRI) were used for diagnosis.
  • Selective angiography confirmed the vascular abnormalities.
  • Pylorus-preserving pancreaticoduodenectomy was performed for surgical management.

Main Results:

  • Imaging revealed irregular, dilated, and meandering vessels in the pancreatic head with early portal vein visualization.
  • Histopathology confirmed the diagnosis of pancreatic head AVM.
  • The patient underwent successful surgical resection.

Conclusions:

  • Symptomatic pancreatic AVM is uncommon but can be definitively managed with surgical treatment.
  • Multimodality imaging is crucial for accurate diagnosis of pancreatic AVM.

Acute Pancreatitis I: Introduction

Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

Pancreas

The pancreas, an essential organ in the human body, is a pinkish-gray elongated structure located posterior to the stomach. It extends laterally from the duodenum towards the spleen and is firmly bound to the posterior wall of the abdominal cavity. The organ's surface has a lumpy, lobular texture that gives it a unique appearance.
The broad head of the pancreas lies within the loop formed by the duodenum, while its slender body reaches towards the spleen. The tail of the pancreas is short...

Acute Pancreatitis II: Clinical Manifestations and Management

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...
