Partial splenic embolization for hypersplenism in renal transplantation
AJR. American Journal of Roentgenology
|March 1, 1982
Summary
Partial splenic embolization offers a less invasive alternative to splenectomy for renal transplant recipients experiencing immunosuppressive therapy intolerance due to hypersplenism. This procedure effectively manages hypersplenism, allowing for continued immunosuppression and prevention of transplant rejection.
Area of Science:
- Nephrology
- Transplant Surgery
- Interventional Radiology
Background:
- Renal transplant recipients require immunosuppressive therapy to prevent organ rejection.
- Hypersplenism with leukopenia/thrombocytopenia can lead to intolerance of immunosuppressive drugs.
- This intolerance compromises transplant outcomes, necessitating alternative management strategies.
Observation:
- Splenectomy, a traditional treatment for hypersplenism, involves surgery, anesthesia, and hospitalization, with risks of severe infection.
- Partial splenic embolization (PSE) was explored as a less invasive alternative.
- Seven patients (6 with acute rejection, 1 awaiting transplant) underwent PSE.
Findings:
- PSE successfully corrected hypersplenism in all treated patients.
- Six patients achieved adequate immunosuppressive therapy control, managing rejection episodes.
- The procedure was associated with no significant complications, unlike splenectomy.
Implications:
- Partial splenic embolization is a viable, safer alternative to splenectomy for managing hypersplenism in transplant patients.
- This technique allows for sustained immunosuppression, improving graft survival rates.
- Adherence to aseptic technique, pain management, and antibiotic prophylaxis is crucial to prevent PSE-related complications.
