Insights

Portal vein thrombosis (PVT) can cause rare common bile duct (CBD) wall thickening mimicking cancer. Colour Doppler ultrasound (CD US) effectively identified collateral circulation in the CBD wall, aiding diagnosis.

Area of Science:

  • Medical Imaging
  • Gastroenterology
  • Vascular Surgery

Background:

  • Common bile duct (CBD) wall thickening due to varicose veins from portal vein thrombosis (PVT) is a rare condition.
  • This presentation can be misdiagnosed as cholangiocarcinoma, posing a diagnostic challenge.

Observation:

  • A patient presented with obstructive jaundice, pancreatic head tumor, CBD wall thickening, and pre-existing PVT.
  • Colour Doppler ultrasound (CD US) was utilized to investigate the cause of the patient's symptoms.

Findings:

  • CD US revealed collateral circulation within the thickened CBD wall, originating from the thrombosed portal vein.
  • This finding successfully differentiated the condition from a CBD mass, such as cholangiocarcinoma.

Implications:

  • Colour Doppler ultrasound is a valuable tool for diagnosing rare cases of CBD wall thickening caused by PVT.
  • Accurate diagnosis is crucial for appropriate patient management and avoiding unnecessary interventions for suspected malignancy.

Esophageal Varices-II: Clinical Features and Management

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol abuse, or...

Esophageal Varices-I: Introduction

Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
