The Leriche syndrome. A comparative investigation using angiography, computed tomography and ultrasonography
Insights
Angiography and computed tomography effectively diagnose Leriche syndrome. However, standard abdominal ultrasonography struggles to identify key features of this aortic thrombotic condition, limiting its diagnostic utility.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Radiology
Background:
- Leriche syndrome involves aortoiliac occlusion, posing diagnostic challenges.
- Accurate imaging is crucial for timely intervention in Leriche syndrome.
Purpose of the Study:
- To compare the diagnostic efficacy of angiography, computed tomography (CT), and ultrasonography for Leriche syndrome.
- To evaluate the ability of different imaging modalities to detect aortic thrombosis.
Main Methods:
- Retrospective analysis of nine patients diagnosed with Leriche syndrome.
- Review of imaging studies including angiography, contrast-enhanced computed tomography, and abdominal ultrasonography.
- Assessment of the ability of each modality to delineate the thrombosed aorta.
Main Results:
- Angiography and computed tomography accurately diagnosed Leriche syndrome in all patients.
- Ultrasonography, using a linear array real-time scanner, failed to establish essential diagnostic features.
- Contrast CT provided detailed visualization of aortic abnormalities, aiding diagnosis.
Conclusions:
- Angiography and contrast-enhanced CT are reliable methods for diagnosing Leriche syndrome.
- Standard abdominal ultrasonography has limitations in visualizing the thrombosed aorta characteristic of Leriche syndrome.
- CT offers superior detail for characterizing aortic pathology in Leriche syndrome.
Abstract:
Nine patients with Leriche syndrome were examined with angiography, computed tomography and routine abdominal ultrasonography. The diagnosis was readily obtained with angiography and computed tomography, while ultrasonography conducted with a linear array real time scanner failed to establish essential features of the disorder. This is mainly because the thrombosed portion of the aorta does not produce any striking alteration of the echo structure of the vessel. Contrast computed tomography defines the abnormalities of the aorta in great detail.
