Digital nerve entrapment due to vascular malformation.

Area of Science:

• Vascular Surgery
• Neurology
• Hand Surgery

Background:

• Digital nerve entrapment is a common cause of hand pain and dysfunction.
• Vascular malformations are abnormal growths of blood vessels that can occur anywhere in the body.

Observation:

• A case of digital nerve entrapment secondary to an underlying vascular malformation is presented.
• The vascular malformation caused extrinsic compression of the digital nerve.

Findings:

• Surgical excision of the vascular malformation led to resolution of the digital nerve entrapment symptoms.
• Histopathological examination confirmed the nature of the vascular malformation.

Implications:

• This case expands the differential diagnosis for digital nerve entrapment.
• Vascular malformations should be considered in the etiology of nerve compression syndromes, particularly in the extremities.
