Insights
Transcatheter arterial embolization effectively treats bleeding after kidney procedures. This safe method preserves kidney function, with high success rates and minimal complications.
Area of Science:
- Interventional Radiology
- Nephrology
- Urology
Background:
- Percutaneous renal procedures can lead to significant bleeding.
- Timely intervention is crucial for managing post-procedural hemorrhage.
Purpose of the Study:
- To evaluate the radiological and clinical outcomes of transcatheter arterial embolization (TAE) for active bleeding post-percutaneous renal procedures.
- To assess the safety and efficacy of TAE in preserving renal function.
Main Methods:
- Retrospective analysis of 79 patients undergoing angiography for percutaneous renal procedure-related bleeding.
- TAE performed for identified bleeding foci or empirically.
- Analysis of technical and clinical success rates, complications, and renal function (eGFR).
Main Results:
- Angiography revealed bleeding in 81% of patients; all underwent TAE.
- Technical success rate was 100% for identified bleeding.
- Clinical success rate was 85.7%, with repeat TAE achieving recovery in all failures.
- No significant difference in eGFR post-TAE; no major complications reported.
Conclusions:
- Transcatheter arterial embolization is a safe and effective treatment for percutaneous renal procedure-related bleeding.
- TAE does not lead to renal function deterioration.
Objectives:
To present the radiological and clinical results of transcatheter arterial embolization in patients with active bleeding after percutaneous renal procedures.
Methods:
A total of 79 consecutive patients who underwent angiography for percutaneous renal procedure-related bleeding were included in the present retrospective analysis. Patient characteristics, angiographic management and clinical outcomes were analyzed.
Results:
On angiography, bleeding foci were observed in 81.0% of the patients (64/79), all of whom underwent transcatheter arterial embolization. Among the 15 patients (19.0%) with negative angiographic findings, empirical transcatheter arterial embolization was carried out in six patients (40.0%). The technical success rate in 64 patients with positive angiographic findings was 100%, and the clinical success rate in 70 patients who underwent transcatheter arterial embolization was 85.7% (60/70). A total of 14.3% (10/70) of patients with clinical failure underwent repeat transcatheter arterial embolization and all achieved clinical recovery. There were no major complications. There was no statistical difference in estimated glomerular filtration rate values before the percutaneous renal procedure and those measured 7 days after transcatheter arterial embolization (43.4 ± 24.4 to 44.6 ± 25.1 mL/min/1.73 m2 ; P = 0.189). Clinical failure was not associated with age, sex, type of renal procedures, bleeding tendency, presence of active bleeding on angiography, latency time and embolic agents used (P > 0.05).
Conclusions:
Transcatheter arterial embolization is a safe and effective method of treating percutaneous renal procedure-related bleeding without renal function deterioration.
