7112 - Aneurysm, any small artery

Alternate Name: Aneural artery dilitation

DBQ: Link to Index of DBQ/Exams by Disability for DC 7112

Definition

An aneurysm is an abnormal, localized expansion of a blood vessel, usually an artery, due to a birth defect or weakness in the wall of the vessel.

Etiology

Causes may be familial, or from trauma, arteriosclerosis, syphilis or fungal infections. The majority of peripheral artery aneurysms involve the popliteal artery.

Signs & Symptoms

The location of the small artery will determine the signs and symptoms. Symptoms are usually due to thrombosis, embolus, or pressure on adjacent structures.

Tests

Diagnosis is usually determined by ultrasound, computed tomography (CT) scan and physical examination. If surgery is planned, then arteriography will be done.

Treatment

If the aneurysm is popliteal, asymptomatic and exceeds 2 cm. in diameter, or if the aneurysm is less than 2 cm. but is symptomatic, then a repair and graft is recommended. Because femoral aneurysms are smaller and have fewer complications, they can be followed rather than be operated upon.

Residuals

Many patients with popliteal aneurysms also have aortoiliac aneurysms.

Special Consideration

  • None.

Notes

  • If symptomatic, evaluate according to body system affected. Following surgery, evaluate residuals under the body system affected.

  • The rating criteria for cardiovascular conditions underwent full-scale revision effective on November 14, 2021 and January 12, 1999.  A regulatory change was effective August 13, 1998, updated criteria for cold injury residuals under 38 CFR 4.104, DC 7122.  The changes are not considered liberalizing and should not be used as the basis for reduction unless the disability has actually improved.
