Duodenal ulcer penetration into the superior mesenteric artery after percutaneous transluminal angioplasty and stent placement for acute mesenteric ischemia: report of a case

Mesenteric Ischemia: Concepts of Care for the Bedside Nurse

Bedside nurses require excellent observational and assessment skills. Being knowledgeable about common diseases that often affect the population is essential; however, it is often more challenging to be informed about life-threatening conditions that rarely develop. Such is the case with mesenteric ischemia, a rare but complicated condition, which is difficult to diagnose, carries a degree of mortality of about 40%-70%, and is more common in people older than 50 years. Mesenteric ischemia requires that nurses be aware of the different etiologies and presentations of this uncommon disease to alert physicians of changes in a patient's condition and detect clues that may assist with an accurate and prompt diagnosis. Being educated about the diagnostic procedures, possible outcomes, and anticipated care and needs of patients affected by this medical complication is imperative to maintain the health status and well-being of these patients and their families.

Surgery for acute exacerbation of chronic mesenteric ischemia: a case report

BACKGROUND

Chronic mesenteric ischemia (CMI) is a rare disease; however, symptomatic CMI has a risk of acute exacerbation without timely revascularization.

CASE PRESENTATION

A 54-year-old man who had had postprandial pain for 6 months was admitted to our hospital because of vomiting and diarrhea. Although the celiac and superior mesenteric arteries were occluded at the proximal portion, contrast enhancement of the bowel wall was good in contrast-enhanced computed tomography (CECT). Endoscopic examination revealed only a healed gastric ulcer and slight mucosal erosions in the colon. He was diagnosed as having acute enteritis or inflammatory digestive disease and observed with conservative therapy, which improved his acute symptoms. On hospitalization day 42, he suddenly complained of lower back pain. CECT showed abdominal free air, which indicated gastrointestinal perforation. Emergency surgery was performed for jejunum resection. Two days later, a second operation was performed for a leak in the anastomotic site of the jejunum. Necrotic change in the small intestinal serosa was also observed and required broad resection of the small intestine. He was diagnosed with acute exacerbation of CMI, and we performed surgical retrograde bypass to the gastroduodenal artery using a saphenous vein graft as the third operation. After the surgery, he was free from digestive symptoms and was discharged.

CONCLUSIONS

When patients complain of chronic and gradual digestive symptoms, we should always consider symptomatic CMI. Timely mesenteric revascularization is important for symptomatic CMI before severe complications occur.
