Summary
Portal vein aneurysms, though once rare, are increasingly diagnosed in young adults with thalassaemia major. Early detection via imaging is crucial to distinguish them from other liver conditions.
Area of Science:
- Vascular Surgery
- Abdominal Imaging
- Hepatology
Background:
- Arterial aneurysms are more prevalent than visceral venous aneurysms.
- Portal vein aneurysms are the most common type of visceral venous aneurysms.
Observation:
- An 18-year-old female with thalassaemia major presented with symptoms including headache, palpitations, and dyspnea.
- Clinical examination revealed hepatosplenomegaly.
- Initial ultrasonography showed hepatosplenomegaly with fusiform dilatation of the extrahepatic portal vein.
Findings:
- Contrast-enhanced CT confirmed the diagnosis of a portal vein aneurysm.
- Portal vein aneurysms are increasingly diagnosed with advancements in cross-sectional imaging.
Implications:
- Accurate diagnosis of portal vein aneurysms is essential to prevent misidentification with other periportal cystic masses.
- Improved diagnostic capabilities aid in differentiating aneurysms from various etiologies, particularly on sonography.

01:24Esophageal Varices-I: Introduction
1.7K
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, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

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...

664
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.

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
