True aneurysm of common digital artery - Case report

INTRODUCTION Aneurysms of digital arteries are considered to be rarity. They could be true or false. False aneurysms are usualy the result of penetrating trauma, while the causes of development of true aneurysms are various, such as blunt trauma, and rarely atherosclerosis, vasculitis and infection. Also, they can be idiopathic. Reviewing the literature we found 13 cases of previously described true aneurysms of digital arteries. None of them referred to the common digital artery aneurysm. CASE OUTLINE We report a case of an idiopathic true aneurysm of the common digital artery, with its clinical presentation and a corresponding multislice CT arteriogram. Surgical treatment by ligation and excision of the aneurysm was performed. CONCLUSION As mentioned above, true aneurysms of digital arteries are very rare, so they are of little clinical importance. The most common symptom of digital artery aneurysms is pain, with a tender pulsatile mass on examination. Since natural healing cannot be expected, surgical treatment of true digital artery aneurysms is recomended for pain relief and avoidance of complications which may occur and are related to the aneurysm presence. Aneurysm resection and ligation of a blood vessel can be performed. Also, artery reconstruction can be performed by primary end-to-end anastomosis or the placement of a reversed interposition vein graft.
