Extended use of computed tomography in the management of complex aortic problems: a learning experience
Insights
Computed tomography (CT) scans offer valuable insights beyond standard aortograms for complex aortic conditions. This imaging technique significantly impacts surgical decisions in nearly 30% of patients with aortic aneurysms or graft complications.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Radiology
Background:
- Aortography is standard for thoracic and abdominal aortic issues.
- Computed tomography (CT) offers advanced visualization.
- Assessing CT's role in complex aortic pathology is crucial.
Purpose of the Study:
- To evaluate the diagnostic and management impact of contrast-enhanced CT scans in patients with thoracic or abdominal aortic diseases.
- To compare CT findings with conventional aortography.
Main Methods:
- Eighty-nine patients with aortic problems underwent both CT and aortography.
- Patients had conditions including aneurysms, graft complications, and aortoiliac occlusion.
- Changes in operative management were tracked based on CT findings.
Main Results:
- CT provided additional diagnostic information in 43.8% of patients.
- Operative management was significantly altered by CT in 29% of cases.
- CT identified specific findings like dissection, rupture, and infection, influencing surgical approach.
Conclusions:
- Contrast-enhanced CT is a valuable adjunct to aortography for complex aortic problems.
- CT significantly impacts operative management decisions in a substantial patient subset.
- CT enhances diagnostic accuracy and guides surgical strategy in vascular interventions.
Abstract:
Eighty-nine patients with clinical problems arising from the thoracic or abdominal aorta had computed tomography (CT) scans with contrast enhancement in addition to standard aortograms. Forty-four patients had aneurysms, 22 had aortic graft complications, and 23 had aortoiliac occlusion. CT scanning provided diagnostic information not apparent by conventional angiography in 39 patients (43.8%). This additional information did not significantly alter the operative management in 13 patients (14.6%). The helpful information provided by CT in these patients included demonstration of gallstones, renal cysts, anomalous venous structures, horseshoe kidney, and femoral anastomotic aneurysms. However, in 26 of 89 patients (29%), the additional data obtained by CT significantly changed the timing or approach to operative management. Management was altered in 12 of 44 patients (28%) with aneurysms, 7 of 22 patients (32%) with aortic graft complications, and 7 of 23 patients (30%) with aortoiliac occlusive disease or suspected distal thromboembolism. Specific information provided by CT included contained aortic aneurysm rupture, aortic dissection, laminated intraluminal thrombus or pseudointima, extent of perigraft infection, aortic atherosclerosis, anastomotic false aneurysm, and thrombus as a source of distal embolization. Thus, CT had a significant impact on operative management. It serves as a valuable adjunct to aortography in patients with complex aortic problems.
