Digital Arteriovenous Malformation. An Uncommon Finding: A Case Report.

Area of Science:

• Vascular Surgery
• Medical Diagnostics

Background:

• Vascular malformations (VMs) are congenital abnormalities of blood vessels, distinct from vascular tumors due to their slow growth.
• Arteriovenous malformations (AVMs) develop early in fetal life and affect approximately 1 in 100,000 individuals.

Purpose of the Study:

• To review the characteristics, diagnosis, and management of arteriovenous malformations.
• To highlight the challenges in treating AVMs, particularly in complex anatomical regions like the hand.

Main Methods:

• Review of existing literature on vascular malformations and AVMs.
• Case presentation of a patient with a hand AVM.

Main Results:

• AVMs can be asymptomatic or cause significant pain, deformity, and disability.
• Angiography is the gold standard for AVM diagnosis, though clinical presentation and other imaging modalities are often used.
• Treatment strategies vary from conservative management to surgical intervention, with surgery posing risks, especially for extensive lesions.

Conclusions:

• Management of AVMs requires careful consideration of lesion characteristics and patient symptoms.
• Hand AVMs present unique surgical challenges due to intricate anatomy, necessitating specialized expertise.
