Abstract:
Congenital pelvic arteriovenous malformation (PAVM) is rare. We present two cases with emphasis on the imaging features. Magnetic resonance angiography (MRA) demonstrates comparable details of the vascular abnormalities as conventional angiography, which should be reserved for pre-embolization evaluation.
Insights
Congenital pelvic arteriovenous malformations (PAVMs) are rare vascular anomalies. Magnetic resonance angiography offers detailed imaging comparable to conventional angiography for PAVM evaluation.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
Background:
- Congenital pelvic arteriovenous malformations (PAVMs) are uncommon vascular anomalies.
- Accurate diagnosis is crucial for effective management.
Observation:
- Two cases of PAVM are presented.
- Detailed imaging features are emphasized.
Findings:
- Magnetic resonance angiography (MRA) provides detailed visualization of vascular abnormalities.
- MRA's diagnostic capability is comparable to conventional angiography for PAVMs.
Implications:
- MRA is a valuable tool for diagnosing PAVMs.
- Conventional angiography should be reserved for pre-embolization assessment.
- Improved imaging may lead to better patient outcomes.
