CONTEXT: Large visceral artery occlusion (LVAO) could underlie right-side colon
ischemia (RSCI) but is little known. OBJECTIVE: To assess patients with RSCI
through long-term follow-up, including features and management of LVAO. MAIN
OUTCOME MEASURES: Mesenteric ischemia and mortality. DESIGN: Retrospective
observational study in an integrated health care system. RESULTS: Of 49 patients
(30 women [61.2%]; mean [standard deviation] age, 69.4 [11.9] years), 19 (38.8%)
underwent surgery?that is, 5 (83.3%) of 6 who developed RSCI in hospital
following surgical procedures and 14 (32.6%) of 43 who had RSCI before
hospitalization (p value = 0.03); overall, 5 (10.2%) died. Among 44 survivors
with a median (range) follow-up of 5.19 (0.03-14.26) years, 5 (11.4%), including
3 (20.0%) of 15 operated cases, had symptomatic LVAO and underwent angioplasty
and stent placement: 2 for abdominal angina that preceded RSCI, 1 for acute
mesenteric ischemia 1 week after resection of RSCI, 1 for RSCI 6 weeks after
resection of left-side ischemia, and 1 for abdominal angina that began 3 years
after spontaneous recovery from RSCI. None had further mesenteric ischemia until
death from nonintestinal disease or the end of follow-up (1.6 to 10.2 years
later). Kaplan-Meier survival estimates for all 44 survivors at 1, 3, 5, and 10
years were 88.6%, 72.3%, 57.6%, and 25.9%, respectively. Thirty-one patients
(70.4%) died during follow-up, 19 (61.3%) of a known cause; the 39 patients not
treated for LVAO lacked mesenteric ischemia. CONCLUSION: Patients with RSCI may
have symptomatic LVAO; therefore, we advise they undergo careful query for
symptoms of abdominal angina and routine visceral artery imaging.
