Mesenteric ischemia: Pathogenesis and challenging diagnostic and therapeutic modalities

Area of Science:

• Gastroenterology
• Vascular Surgery
• Diagnostic Imaging

Background:

• Mesenteric ischemia (MI) is a critical condition characterized by insufficient blood supply to the bowel, leading to inflammation and potential necrosis.
• MI encompasses acute (AMI) and chronic (CMI) forms, with AMI presenting diverse causes like embolism, thrombosis, or non-occlusive events.
• CMI is predominantly linked to atherosclerotic disease, often diagnosed late due to subtle symptoms.

Purpose of the Study:

• To review and evaluate the outcomes of surgical treatments for mesenteric ischemia.
• To present current literature and update concepts on the surgical management of MI.

Main Methods:

• Review of recent literature on surgical management of mesenteric ischemia.
• Analysis of diagnostic modalities including CT angiography, conventional angiography, and duplex ultrasonography.
• Evaluation of surgical techniques such as arteriotomy, endarterectomy, bypass, and bowel resection.

Main Results:

• Surgical restoration of blood flow and resection of necrotic bowel are key components of MI treatment.
• Diagnostic imaging plays a vital role in the timely diagnosis and management planning for both acute and chronic mesenteric ischemia.
• Various surgical approaches exist for restoring mesenteric blood flow, tailored to the specific cause and extent of ischemia.

Conclusions:

• Effective surgical management of mesenteric ischemia requires prompt diagnosis and appropriate intervention to restore blood flow and prevent bowel necrosis.
• Continued research and literature review are essential for refining surgical techniques and improving patient outcomes in mesenteric ischemia.
• A multidisciplinary approach combining medical and surgical strategies is optimal for managing this complex condition.
