Abstract
Background
Renal artery pseudoaneurysms are rarely described sequelae of blunt abdominal trauma.
Interventional radiological advances have allowed such lesions to be managed nonoperatively.
Methods
The authors review the presentation, diagnostic evaluation, and hospital course of
an 11-year-old girl who developed a right renal artery pseudoaneurysm 14 days after
blunt abdominal trauma.
Results
An 11-year-old girl fell off a horse onto her right flank. She sustained multiple
right hepatic lobe lacerations and a complex fracture of the upper pole of the right
kidney. Her initial hospital course was uncomplicated, and she was discharged after
an uneventful 6-day course. The child did well for 2 weeks, until she developed right
back pain and gross hematuria. A computed tomography scan revealed a right renal artery
pseudoaneurysm. Angiography confirmed the presence of a pseudoaneurysm, which was
fed by a single segmental branch originating from the renal artery. The artery was
successfully occluded with a single platinum microcoil, which was demonstrated by
the absence of contrast flow into the pseudoaneurysm. The patient recovered and was
discharged shortly after the procedure. She initially had intermittent pain and hematuria,
which resolved. Follow-up computed tomography scans have shown resolution of both
the renal and hepatic lesions.
Conclusions
Renal artery pseudoaneurysms that arise after blunt abdominal trauma in the pediatric
population may be safely and effectively managed with arterial embolization, thereby
avoiding extensive surgical interventions.
