Summary
Three-dimensional multiphase contrast-enhanced MR angiography (3D DCE-MRA) effectively detects portal vein aneurysms (PVA) and associated findings. This imaging technique aids in diagnosis and treatment planning for PVA.
Area of Science:
- Radiology
- Vascular Imaging
- Medical Diagnostics
Background:
- Portal vein aneurysms (PVA) are rare vascular anomalies.
- PVA can present with diverse and complex associated findings.
- Accurate imaging is crucial for diagnosis and management.
Purpose of the Study:
- To investigate imaging features of portal vein aneurysms (PVA).
- To evaluate the diagnostic value of three-dimensional multiphase contrast-enhanced MR angiography (3D DCE-MRA) in detecting PVA and associated findings.
- To provide information for clinical treatment decisions.
Main Methods:
- Retrospective analysis of 10 patients with PVA.
- Utilized 3D DCE-MRA with advanced post-processing techniques.
- Detailed analysis of imaging features and anatomical locations of PVA.
Main Results:
- PVA were identified in various locations including splenic, intrahepatic, and main portal veins.
- Maximal PVA diameters ranged from 2.0 to 8.39 cm (mean 3.72 cm).
- Associated findings included portal vein cavernous transformation, arterio-portal fistulas, arteriovenous malformations, and splenic artery aneurysms.
Conclusions:
- 3D DCE-MRA is highly effective for detecting PVA.
- This technique improves the diagnosis of complex associated vascular findings.
- 3D DCE-MRA provides valuable information for guiding clinical management of PVA.

01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
01:20Venous 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...
01:22Portal Hypertension
Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...
01:24Esophageal 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...
01:30Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
01:30Venous Thrombosis I: Introduction
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...
