Abstract

Insights

Isolated celiac and superior mesenteric artery (SMA) dissections are rare but often asymptomatic. Advanced imaging improves detection, and most cases can be managed with observation, reserving intervention for vascular compromise.

Area of Science:

  • Vascular Surgery
  • Diagnostic Imaging
  • Gastroenterology

Background:

  • Isolated celiac artery (CA) and superior mesenteric artery (SMA) dissections are uncommon conditions.
  • These dissections typically occur without associated aortic dissection.

Purpose of the Study:

  • To describe the imaging findings and clinical outcomes of isolated CA and SMA dissections.
  • To evaluate the diagnostic utility of advanced imaging techniques.

Main Methods:

  • Retrospective analysis of medical records and imaging from 2004 to 2010.
  • Inclusion of dissections of the CA and/or SMA without concurrent aortic dissection.
  • Utilized standard imaging planes and advanced techniques like multiplanar reconstruction (MPR), maximum intensity projection (MIP), and 3D rendering.

Main Results:

  • Identified 24 CA dissections and 18 SMA dissections in 38 patients.
  • Advanced imaging (MPR/MIP/3D) detected one-third of dissections missed on standard views.
  • No patients experienced bowel ischemia or mortality; 84% were managed conservatively with observation.

Conclusions:

  • Isolated CA and SMA dissections are frequently asymptomatic or incidental findings.
  • Observation and surveillance are appropriate management strategies, with intervention reserved for cases of vascular compromise.
  • Interactive MPR/MIP/3D rendering enhances diagnostic sensitivity for these rare dissections.
