Recognition of splenic vein occlusion

Area of Science:

• Radiology
• Gastroenterology
• Vascular Imaging

Background:

• Splenic vein occlusion (SVO) is a significant vascular condition.
• Common causes include pancreatic carcinoma, pancreatitis, and malignant lymphoma.
• Accurate diagnosis is crucial for patient management.

Purpose of the Study:

• To review radiologic findings associated with splenic vein occlusion.
• To identify key diagnostic indicators for SVO.
• To correlate radiographic signs with underlying etiologies.

Main Methods:

• Retrospective review of medical records and angiographic findings.
• Analysis of 27 patients with confirmed splenic vein occlusion.
• Evaluation of barium studies and rapid sequence pyelography.

Main Results:

• Gastric varices without esophageal varices are a key indicator of SVO.
• Collateral veins in the left upper abdomen are suggestive during pyelography.
• Pancreatic calcification and upper abdominal masses may indicate underlying disease.
• High-dose celiac or splenic angiography confirmed the diagnosis.
• Barium examination for gastric varices demonstrated high sensitivity.

Conclusions:

• Radiographic detection of isolated gastric varices can suggest isolated splenic vein occlusion.
• Specific imaging findings aid in the diagnosis of SVO and its causes.
• Early identification through characteristic radiologic signs is essential.
