Primary axillary venous aneurysm: report of a case.

We report a case of nontraumatic, spontaneous venous aneurysm of the left axillary vein. This case may represent only the second such case ever reported in the English-language medical literature. Venous aneurysms are often associated with trauma, arteriovenous fistula, or other venous abnormal hemodynamic conditions, but true primary venous aneurysms are very rare. Surgical excision was uncomplicated and performed easily.
