Learning Objectives:

Discuss the presentation of acute upper extremity limb ischemia.

Review the evaluation of patients with acute upper extremity limb ischemia.

Present common and unique presentations of acute upper extremity limb ischemia including arterial thoracic outlet syndrome and hypothenar hammer syndrome.

Background: Acute upper extremity limb ischemia is relatively uncommon accounting for approximately one fifth of acute limb ischemia presentations. Furthermore, while most lower extremity presentations are of atherosclerotic origin, upper extremity limb ischemia includes many unique pathologic conditions specific to the extremity, each with their own unique treatment implications.

Clinical Findings/Procedure Details: We present several cases of acute upper extremity limb ischemia including arterial thoracic outlet syndrome and hypothenar hammer syndrome. In these cases, we discuss the patient presentation and highlight the role of endovascular therapy including catheter directed thrombolysis, thrombectomy and adjuvant angioplasty/stenting. Further, we identify the role of endovascular interventions alongside complementary medical and surgical treatment strategies in addressing acute upper extremity limb ischemia.

Conclusion and/or Teaching Points:

Understand endovascular approaches to treating acute upper extremity limb ischemia including uncommon etiologies such as arterial thoracic outlet syndrome and hypothenar hammer syndrome.

Recognize treatment options and factors which will assist the interventionalist in clinical decision making.
