Surgery is indicated if symptoms persist and survival of the finger or hand is in question. Nitropaste placed on the finger or affected site has also been used, as has sublingual nifedipine. The patient may be prescribed a vasodilator for partial obstructions to a blood vessel. While the patient is waiting for results of clinical tests, several nonsurgical options are available. Diseases associated with peripheral aneurysms include Kawasaki’s syndrome, Buerger’s disease, and hemophilia. ![]() Other causes of a false aneurysm include arterial punctures from blood gas analysis, cannulation of a vein or axillary arterial injury during a brachial plexus injection, as well as unrecognized arterial bleeders during operations. Stab wounds, gunshots, and displaced fractures, or recurrent bleeding from hemophilia are all causes of a false aneurysm. Hemorrhage from the vessel forms a contiguous hematoma that forms a fibrous shell adjacent to the vessel. Damage occurs to the arterial wall media to cause vessel dilation.įalse aneurysms occur from a penetrating arterial injury or from a complete rupture of the vessel wall when continuity is maintained by the surrounding soft tissue. These arise from occupational hazards, thoracic outlet syndrome, or a malignancy. True aneurysms occur after blunt trauma to the upper extremity. Traumatic aneurysms can be subgrouped into true and false aneurysms. (B) Close-up view of the palm.Īneurysms are classified into two groups: traumatic and nontraumatic. (A) Arteriography of the forearm and digital subtraction angiography of the palm. Angiography provided definitive information regarding the location and extent of arterial injury ( Fig. Doppler flow assessment, pulse volume recordings, and angiography were also obtained. Radiographs of the patient’s hand were obtained.
