Iatrogenic aortic dissection, a complication of angiographic procedures, presents in various types and locations. Computed tomography (CT) aids in diagnosis and monitoring, with retrograde dissections often resolving without surgery.

Area of Science:

  • Cardiovascular Imaging
  • Interventional Radiology
  • Vascular Surgery

Background:

  • Angiographic procedures carry a risk of iatrogenic complications.
  • Aortic dissection is a serious vascular emergency.
  • Understanding iatrogenic aortic dissection is crucial for patient safety.

Purpose of the Study:

  • To detail the presentation, clinical course, and outcomes of aortic dissection.
  • To investigate dissections specifically caused by angiographic procedures.

Main Methods:

  • Retrospective review of approximately 15,500 angiographic procedures (1985-1991).
  • Identification and analysis of six cases of iatrogenic aortic dissection.
  • Utilized computed tomography (CT) for diagnosis and follow-up.

Main Results:

  • Dissections were Stanford type A (3 patients) and type B (3 patients).
  • Injury sites included abdominal aorta, brachiocephalic artery, thoracic aorta, and iliac artery.
  • Retrograde dissections resolved spontaneously, while anterograde dissections persisted; all managed non-surgically.

Conclusions:

  • Angiographers must recognize and anticipate iatrogenic aortic dissection.
  • CT is effective for determining the extent and type of dissection.
  • Non-surgical management can be successful for certain types of iatrogenic aortic dissection.
