Transcatheter hemostasis in the genitourinary tract

Area of Science:

• Interventional Radiology
• Vascular Surgery
• Urology

Background:

• Genitourinary hemorrhage presents diverse etiologies, including trauma, arteriovenous fistulas, and neoplasms.
• Effective hemostasis is crucial for patient outcomes, minimizing morbidity and mortality.
• Traditional surgical approaches may involve significant tissue sacrifice and prolonged recovery.

Purpose of the Study:

• To evaluate the efficacy and applicability of transcatheter hemostasis for various genitourinary bleeding sources.
• To highlight the advantages of endovascular techniques in managing complex vascular lesions.
• To provide an overview of embolization strategies tailored to specific pathologies.

Main Methods:

• Transcatheter arterial embolization using various agents (e.g., glue, Ivalon, large emboli).
• Assessment of arteriovenous fistula flow dynamics to guide embolization technique.
• Catheter-directed therapy for hemorrhage control in trauma and neoplastic cases.

Main Results:

• Transcatheter hemostasis achieved successful hemorrhage cessation in a wide range of genitourinary conditions.
• Temporary vessel occlusion proved effective in trauma management, preserving renal parenchyma.
• Arteriovenous fistulas were successfully occluded, with technique selection based on fistula size and flow.
• Neoplastic-related hemorrhage was also effectively controlled via embolization.

Conclusions:

• Transcatheter hemostasis is a versatile and effective treatment for genitourinary hemorrhage.
• The technique offers a parenchyma-sparing alternative, particularly in trauma management.
• Tailored embolization strategies ensure successful outcomes for arteriovenous fistulas and neoplasms.
