Overview
Acute gastrointestinal tract (GIT) vascular insufficiency involves compromised blood flow to the gastrointestinal mucosa, often leading to severe complications such as ischemia, bleeding, or perforation in older adults 2.Diagnosis
Clinical presentation includes abdominal pain, nausea, vomiting, and hematemesis or melena 2.
Diagnostic imaging: CT angiography or mesenteric Doppler ultrasound to assess vascular patency and perfusion 2.
Laboratory tests: Elevated lactate levels, leukocytosis, and coagulation profile abnormalities 2.Management
First-line treatments: Immediate fluid resuscitation and hemodynamic stabilization 2.
Anticoagulation: Consideration of anticoagulation in non-acute thrombotic events, tailored to patient-specific risk factors 2.
Surgical intervention: Indicated for persistent ischemia, perforation, or failure of medical management 2.
Monitoring: Continuous hemodynamic monitoring and frequent reassessment of abdominal symptoms 2.Special Populations
Elderly: Increased focus on geriatric-specific considerations, including multimorbidity management and functional status assessment 12.Key Recommendations
Implement specialized prehospital training for geriatric emergencies to enhance early recognition and management of acute GIT vascular insufficiency (Evidence: Expert opinion 1).
Utilize condition-specific protocols for early intervention in older adults presenting with severe gastrointestinal symptoms (Evidence: Moderate 2).
Prioritize multidisciplinary care involving emergency, inpatient, and potentially outpatient settings to address complex comorbidities in elderly patients (Evidence: Expert opinion 2).References
