Summary
Renal arterial thrombosis can lead to acute kidney injury. Prompt ultrasonography to detect venous flow may reveal collateral vessels, guiding timely angioplasty for favorable outcomes in single-kidney patients.
Area of Science:
- Nephrology
- Vascular Surgery
- Radiology
Background:
- Renal arterial thrombosis (RAT) causes kidney ischemia, with outcomes varying based on etiology and collateralization.
- Traumatic RAT often leads to rapid infarction, while non-traumatic RAT may allow for collateral vessel development, prolonging ischemia without necrosis.
Observation:
- A case report details acute renal failure in a patient with a single functional kidney due to RAT.
- The patient presented with delayed symptoms, highlighting the potential for prolonged ischemia without immediate necrosis.
Findings:
- Delayed treatment with percutaneous angioplasty resulted in a favorable outcome.
- Ultrasonography detection of venous renal flow indicated significant collateral vascularization.
Implications:
- Ultrasonography for venous renal flow is valuable for assessing collateralization in RAT.
- Arteriography with angioplasty should be considered even in delayed presentations of RAT, especially in single-kidney patients.
