Article Title: Acute limb ischemia in a cancer patient has high morbidity, high mortality, and atypical presentation: A tertiary cancer center’s retrospective study
Abstract: Background: Acute Limb Ischemia (ALI) carries a high morbidity and mortality rate that is compounded in the cancer patient. Though it is a relatively uncommon event, it is of extremely high adverse impact and carries poor awareness among clinicians. Methods: Retrospective review of electronic medical records was performed of cancer patients presenting with acute limb ischemia (ALI) to the tertiary cancer center’s urgent care center or as inpatient between January 1, 2014 and January 1, 2020. Results: Out of the 29 cancer patients with ALI, 12 (41%) died within 3 month and 9 (31%) patients died within 1 months of ALI diagnosis. 65% had long term adverse outcome after ALI – 31% with death in 1 month, 2 (7%) with an amputation, 5 (17%) with lifestyle-limiting claudication, and 3 (10%) with subsequent wound ulceration or gangrene. Patients not eligible for standard of care (12 patients, 41%) (RR 2.33 95% CI [1.27–4.27], p < 0.01) and heparin administration ≥6 h from presentation (19 patients, 65%) (RR 2.81 [1.07–7.38], p = 0.04) were at increased risk of adverse outcome. Atypical/confounded presentation of ALI (13 patients, 45%) (RR 1.84 95% CI [1.03–3.29], p = 0.04), pulse exam not documented (12 patients, 41.4%) (RR 1.95 [95% CI [1.14–3.32], p = 0.01), and patients with services other than a vascular specialist initially consulted (8 patients, 27.6%) (RR 1.91 95% CI [1.27–2.87], p < 0.01) were significant risk factors for heparin administered ≥6 h from presentation. Conclusions: ALI is devastating in cancer patients, with a high number presenting with atypical/confounded signs and symptoms which delays treatment. Heparin administered ≥6 h from presentation is associated with adverse outcome. © 2021, The Author(s).
