Evaluation of vascular rings with digital subtraction angiography
Insights
Digital subtraction angiography (DSA) effectively diagnosed vascular rings in seven patients. This imaging technique is a viable alternative to traditional arteriography for diagnosing these rare congenital anomalies.
Area of Science:
- Cardiovascular Imaging
- Pediatric Radiology
- Diagnostic Angiography
Background:
- Vascular rings are rare congenital anomalies that can cause significant morbidity.
- Accurate diagnosis is crucial for timely surgical intervention.
- Traditional angiography methods have limitations in visualizing these complex structures.
Observation:
- Seven patients with suspected vascular rings were evaluated using intravenous digital subtraction angiography (DSA).
- DSA imaging was compared with screen-film aortography or cineangiography and barium esophagography.
- The diagnostic yield and accuracy of DSA were assessed against surgical confirmation.
Findings:
- Six out of seven (85.7%) DSA studies were completely diagnostic for vascular rings.
- One DSA study provided partial diagnostic information.
- Six of the seven surgically confirmed vascular anomalies were accurately identified by DSA.
Implications:
- Intravenous digital subtraction angiography (DSA) demonstrates high diagnostic accuracy for vascular rings.
- DSA offers a valuable alternative to conventional arteriography in the evaluation of suspected vascular rings.
- This imaging modality can aid in surgical planning and improve patient outcomes for congenital vascular anomalies.
Abstract:
Seven patients with vascular rings were evaluated over a 2-year period with intravenous digital subtraction angiography (DSA), which was compared with screen-film aortography or cineangiography. The seven patients were also evaluated with barium esophagography. Six of the seven DSA images were totally diagnostic and one study was only partly diagnostic. Six of the seven vascular anomalies were confirmed surgically. DSA is suggested as an alternative to arteriography in evaluating patients with suspected vascular rings.
