Iatrogenic Aortic Intramural Hematoma: Guidance to Intraoperative Decision Making: A Case Report

Area of Science:

• Cardiovascular Surgery
• Vascular Medicine
• Diagnostic Imaging

Background:

• Aortic intramural hematoma (IMH) is a variant of acute aortic syndrome (AAS), distinct from aortic dissection (AD).
• Management principles for IMH and AD have traditionally been similar, often guided by the Stanford classification.
• Advances in imaging technology are revealing specific IMH features that influence its natural progression.

Observation:

• The case involved iatrogenic IMH developing as a complication during a standard coronary artery bypass graft (CABG) procedure.
• Intraoperative imaging played a crucial role in assessing the IMH and guiding clinical decisions.

Findings:

• Specific imaging features of IMH were identified that impact its natural course.
• The case highlights the successful application of imaging in determining the optimal management strategy.

Implications:

• This case underscores the importance of advanced imaging in managing AAS complications like iatrogenic IMH.
• It demonstrates that conservative management, guided by imaging, can be a viable option for certain IMH cases post-CABG.
• Further research into imaging-based stratification for IMH management is warranted.
