This paper documents the various causes of upper limb ischemia in a series of 64 Egyptian patients presenting to a tertiary referral center over a 4-year period and offers a diagnostic dissertation and review of the pertinent literature. Atraumatic upper limb ischemia is an uncommon entity. It has a broad etiology with diverse management pathways. Nineteen patients presented with severe and immediate limb-threatening ischemia. These patients underwent immediate surgical exploration: an embolus was diagnosed in 15 and thrombosis in 4. Twenty-eight patients presented with ischemia of lesser severity, allowing preoperative angiography. Of these 28 patients, 6 had an embolus, 14 had thrombosis, 4 had thoracic outlet syndrome, the remainder had miscellaneous causes. Fifteen patients had upper limb ischemia secondary to arteritis, and 2 patients with dissection of the ascending thoracic aorta presented with upper limb ischemia. Forty-seven patients underwent a surgical procedure, with a morbidity rate of 21% and mortality rate of 19%. Patients presenting with upper limb ischemia tend to have significant co-existing disease. Management of upper limb ischemia requires preoperative and/or peroperative angiography with careful application of vascular surgical expertise.
