Summary
Digital angiography effectively diagnoses vascular erectile dysfunction, with intravenous contrast offering a quicker, less invasive, and equally effective alternative to arterial catheterization. This method aids in identifying penile artery steno-occlusive lesions.
Area of Science:
- Vascular Surgery
- Radiology
- Urology
Background:
- Erectile failure often stems from vascular issues.
- Accurate diagnosis of penile artery disease is crucial for effective treatment.
Purpose of the Study:
- To evaluate digital angiography for diagnosing vascular erectile dysfunction.
- To compare intravenous and intra-arterial contrast administration methods.
- To correlate angiographic findings with functional tests.
Main Methods:
- Digital angiography of pudendal and penile arteries in 44 patients.
- Comparison of intravenous (IV) and selective intra-arterial (IA) contrast injection.
- Functional assessment using nocturnal penile tumescence (NPT) and Doppler ultrasonography (DUS).
Main Results:
- 73% of patients showed penile artery steno-occlusive lesions.
- IV digital angiography yielded results comparable to IA catheterization.
- IV angiography was faster and less invasive, visualizing both arterial networks simultaneously.
- NPT results correlated well with angiographic findings; DUS was less sensitive.
Conclusions:
- Digital angiography is a valuable tool for diagnosing vascular erectile dysfunction.
- Intravenous digital angiography is a safe, efficient, and effective alternative to selective arterial catheterization.
- Angiographic findings align with NPT, supporting its role in assessing vascular erectile dysfunction severity.
