Post transplant thrombotic microangiopathy causing acute renal failure

Area of Science:

• Nephrology
• Transplant Medicine
• Pathology

Background:

• Acute Renal Failure (ARF) is a common complication following kidney transplantation.
• Typical causes include acute tubular necrosis, rejection, and drug toxicity, alongside prerenal and postrenal factors.

Observation:

• This case report details an unusual etiology of ARF in the immediate post-transplant period.
• The patient presented with symptoms indicative of a serious renal complication shortly after receiving a new kidney.

Findings:

• The primary finding is the diagnosis of thrombotic microangiopathy (TMA) as the cause of ARF.
• This contrasts with the more frequent causes of post-transplant ARF, presenting a diagnostic challenge.

Implications:

• Recognizing TMA as a cause of post-transplant ARF is crucial for timely and appropriate management.
• This case underscores the importance of considering less common pathologies in the differential diagnosis of early post-transplant renal dysfunction.
