Summary
Digital subtraction angiography (DSA) effectively diagnoses aortic anomalies like aneurysms and stenoses. Intravenous DSA proved reliable for thoracic and abdominal aorta imaging, with a low non-diagnostic rate.
Area of Science:
- Vascular Imaging
- Diagnostic Radiology
Background:
- Digital subtraction angiography (DSA) is a key imaging modality.
- Assessment of the thoracic and abdominal aorta is crucial for diagnosing various vascular conditions.
Purpose of the Study:
- To analyze the diagnostic efficacy of digital subtraction angiography (DSA) for the thoracic and abdominal aorta.
- To evaluate the quality and diagnostic yield of intravenous (I-V) DSA compared to intra-arterial (I-A) DSA.
Main Methods:
- Retrospective analysis of 300 digital subtraction angiography (DSA) examinations of the thoracic and abdominal aorta.
- Contrast material was administered via intravenous (I-V) and intra-arterial (I-A) injections.
- Image quality and diagnostic accuracy were assessed.
Main Results:
- All intra-arterial (I-A) DSA examinations were of good quality and diagnostic.
- Intravenous (I-V) DSA yielded diagnostic results for most thoracic and abdominal aortograms, with only 1.8% and 1.2% non-diagnostic rates, respectively.
- I-V DSA successfully identified anomalies in aortic position, dilatation (aneurysms), and stenoses (coarctations, arteriosclerosis, occlusions).
Conclusions:
- Intravenous (I-V) DSA is a reliable and effective method for diagnosing thoracic and abdominal aortic pathologies.
- The diagnostic performance of I-V DSA is high, with a minimal rate of non-diagnostic examinations.
- DSA, particularly I-V DSA, facilitates the diagnosis of significant aortic diseases, aiding in clinical management and pre-operative planning.
