Successful surgical repair of an eminently rare case of an incidental idiopathic Common Femoral Artery Pseudoaneurysm in a 6-year-old female child - A Case Report.

Introduction And Importance: A Pseudoaneurysm is an abnormal outpouching of the arterial wall which progressively enlarges and could lead to catastrophic consequences. Ensuing damage could culminate in the loss of the affected extremity due to dissection, exsanguination, thromboembolism, or infection. Some presentations are symptomatic, whereas others are incidental findings. Timely surgical mediation is vital to eliminate the potential morbid sequelae.

Case Presentation: We present the case of a 6-year-old female, who was referred to the clinic due to an incidental finding of a pulsatile bulge in her right groin. We confirmed the presence of a visible pulsating bulge in the right groin associated with impalpable Popliteal and Pedal pulses. Preoperative imaging revealed an isolated Common Femoral Artery Pseudoaneurysm and hence, surgical intervention was successfully accomplished.

Clinical Discussion: Surgical repair was achieved by pseudoaneurysmectomy and utilizing an autologous Saphenous Vein graft. From the proximal side, a primary end-to-end anastomosis was accomplished between the veinous graft and the right Common Femoral Artery (CFA). Whereas from the distal side, a direct end-to-end anastomosis was completed between the right Superficial Femoral Artery and the veinous graft.

Conclusion: Arterial pseudoaneurysms constitute immensely rare vascular emergencies. The pediatric population is particularly vulnerable because of the rarity of occurrence of this pathology in children. Surgical intervention is the gold standard approach. Meticulous follow-up protocols ought to be carried-out to limit the possibility of recurrence. Documentation is the main building block in our profession. Physicians should possess high sense of clinical awareness when presented with such a pathology.
