Renal allograft venous thrombosis is salvageable

Area of Science:

• Nephrology
• Transplant Surgery
• Vascular Surgery

Background:

• Renal vein thrombosis (RVT) is a rare but severe complication following kidney transplantation.
• It typically manifests within the first two weeks post-surgery, often presenting with nonspecific symptoms.
• Common causes include renal vein compression, early graft rejection, and hemostatic defects.

Observation:

• A retrospective review of 684 kidney transplant recipients identified seven cases of biopsy-proven RVT.
• The diagnosis was suspected based on decreased urine output, elevated creatinine, or hematuria, and confirmed by Doppler ultrasound and isotope scanning.
• Four of the affected grafts were from cadaveric donors.

Findings:

• The incidence of RVT in this series was 1%, with all cases occurring within the first 14 days post-transplant.
• RVT was more prevalent in adult, female, and cadaveric graft recipients.
• Three out of seven affected kidney grafts were successfully salvaged through prompt intervention.

Implications:

• This study highlights the importance of vigilant monitoring for RVT in the early post-transplant period.
• Prompt diagnosis and surgical intervention are critical for improving graft survival rates in RVT cases.
• Understanding risk factors such as donor type and recipient demographics can aid in early detection and management.
