Transplant Renal Vein Thrombosis

Area of Science:

• Nephrology
• Transplant Surgery
• Vascular Surgery

Background:

• Transplant renal vein thrombosis (TRVT) is a rare but severe complication following kidney transplantation, occurring in 0.1% to 4.2% of cases.
• It frequently leads to the loss of the transplanted kidney graft.
• Mechanical factors are primary contributors to TRVT, alongside donor, recipient, surgical, and immunosuppression-related factors.

Purpose of the Study:

• To review the causes, clinical manifestations, diagnostic methods, and therapeutic options for transplant renal vein thrombosis.
• To emphasize the importance of early diagnosis and intervention in managing TRVT.
• To discuss the outcomes of current treatment strategies for TRVT.

Main Methods:

• Literature review of transplant renal vein thrombosis.
• Analysis of predisposing factors, clinical presentation, and diagnostic modalities.
• Evaluation of treatment outcomes for thrombolytic therapy and surgical thrombectomy.

Main Results:

• TRVT typically manifests early post-transplant, with nonspecific symptoms mimicking other complications like urine leak or rejection.
• Diagnosis relies on clinical suspicion and duplex ultrasonography, though venography is the gold standard.
• Both thrombolytic therapy and surgical thrombectomy are described treatment options, with varying success rates.

Conclusions:

• Transplant renal vein thrombosis is a critical complication necessitating prompt recognition and management.
• Effective treatment strategies, including thrombolysis and surgery, are vital for preserving renal allograft function.
• Despite interventions, renal allograft loss remains a common outcome in cases of TRVT.
