Summary
Renal artery intimal tears from trauma can cause stenosis. Dynamic helical computed tomography (CT) identified this injury, and endovascular stent placement successfully treated two patients, preserving kidney function.
Area of Science:
- Vascular Surgery
- Radiology
- Trauma Surgery
Background:
- Intimal tears in renal arteries often stem from rapid deceleration trauma.
- These injuries can lead to thrombosis and luminal stenosis, threatening renal function.
- Early diagnosis and intervention are crucial for preserving parenchymal function.
Observation:
- Dynamic helical computed tomography (CT) revealed unilateral delay in renal contrast enhancement.
- This enhancement delay indicated arterial stenosis secondary to intimal dissection.
- Arteriography confirmed the intimal dissection in both cases.
Findings:
- Two patients with traumatic renal artery intimal dissection were successfully diagnosed using dynamic helical CT.
- Endovascular stent placement was the chosen treatment, achieving successful vessel repair.
- This diagnostic and therapeutic approach is novel, with no prior literature describing it.
Implications:
- Dynamic helical CT is a valuable tool for diagnosing renal artery intimal dissection.
- Endovascular stent placement offers a viable treatment option for these injuries.
- This strategy can help preserve renal function in trauma patients.
