Article Abstract
Non-occlusive mesenteric ischemia (NOMI) is a rare complication after transcatheter aortic valve replacement (TAVR), with a poorly understood pathogenesis. We present the case of a 79-year-old female with a history of surgically repaired abdominal aortic aneurysm (AAA) and stable thoracic aortic aneurysm (TAA) who developed NOMI after TAVR, resulting in extensive bowel necrosis and patient mortality. Our case highlights the special attention that must be paid to patients with a history of endovascular interventions prior to TAVR due to the risk of postprocedural NOMI. We propose that NOMI after TAVR occurs from the reduction in cardiac output due to rapid pacing during valve deployment, resulting in worsening splanchnic hypoperfusion in patients with existing mesenteric vascular disease.

Risk Factors for 30-day Mortality After Emergency Surgery for Non-occlusive Mesenteric Ischemia.

Department of Gastroenterological Surgery, Saitama Medical University International Medical Center, Saitama, Japan.
Background/aim: Non-occlusive mesenteric ischemia (NOMI) is a rare and highly fatal disease characterized by intestinal ischemia or necrosis despite the absence of obstruction of the mesenteric vessels. This research aimed to investigate the risk factors for 30-day mortality of NOMI after emergency surgery.
Patients And Methods: We analyzed 42 consecutive patients who underwent emergency surgery for NOMI from April 2015 to August 2022.

An 81-year-old man was brought to our institution because of general fatigue, loss of appetite, and decreased consciousness. Based on the clinical findings, the patient was diagnosed with diabetic ketoacidosis (DKA) and started on insulin therapy. Two days after normalization of the ketone body level, he developed a high fever and abdominal pain.

Background: Both cardiopulmonary resuscitation (CPR) and ischaemia could lead to abdominal organ injury. However, the importance of abdominal injury in cardiac arrest remains uncertain. We aimed to systematically review indexed literature to describe incidence of abdominal injury after non-traumatic cardiac arrest and associations with outcome.

We assessed the efficacy and feasibility of hydrogen inhalation therapy in swine models of critically ill conditions leading to non-occlusive mesenteric ischemia (NOMI) without acute surgical intervention.
Methods: NOMI was induced in eight 3- to 4-month-old female swine under general anesthesia.
