Portosystemic arteriovenous fistula. Case report.
Acta Chirurgica Scandinavica
|January 1, 1975
Summary
This case study discusses a rare portosystemic arteriovenous fistula, a serious condition often leading to fatal variceal bleeding. Surgical intervention is recommended due to circulatory strain and portal hypertension risks.
Area of Science:
- Vascular Surgery
- Gastroenterology
- Interventional Radiology
Background:
- Portosystemic arteriovenous fistulas are uncommon vascular lesions.
- These fistulas can arise from hepatic or splenic artery aneurysms, trauma, or surgical complications.
Observation:
- A case of a rare portosystemic arteriovenous fistula is presented.
- The predominant cause of mortality associated with this condition is variceal bleeding.
Findings:
- Angiography is crucial for diagnosing and defining portosystemic arteriovenous fistulas.
- Treatment options include excision, vessel reconstruction, or ligation, depending on resectability.
Implications:
- Portosystemic arteriovenous fistulas create significant circulatory strain and risk portal hypertension, even in asymptomatic individuals.
- Surgical treatment is indicated for all patients diagnosed with a portosystemic arteriovenous fistula due to these risks.
