Imaging Procedures and Findings
Selective renal arteriogram depicts a pseudoaneurysm in a segmental branch of renal artery at its lower pole. No evidence of A-V fistula is seen.
Injury to kidney is not rare in either penetrating or major blunt trauma. A full range of vascular injuries can be seen from hematuria without visible injury (grade 1) to a shattered kidney or renal hilum avulsion (grade 5). Angiography is most often performed in these patients to determine the extent of injury and therapeutic planning, which may be surgical or via endovascular means. A special type of trauma to the kidney, of course, is iatrogenic, including biopsy or catheter placement. This also includes the renal transplant, which might be undergoing repeated biopsies. Angiography is performed to determine the site and nature of the injury, which could be pseudoaneurysm, arteriovenous fistula, or even extravasation. Most of these injury sites are amenable to endovascular treatment, most often by subselective catheterization and coiling.
