Superficial Femoral Artery Interposition Graft for Repair of a Ruptured Mycotic Common Carotid Artery Pseudoaneurysm: Case Report and Review of the Literature.



Document Type



BACKGROUND: Indications for reconstruction of the common carotid artery (CCA) include trauma, iatrogenic injury, neoplastic growth (such as invasive neck carcinomas), postoperative infection, and cervical carotid aneurysm. Although various techniques and conduits have been described, the clinical scenario may preclude the use of the most commonly used grafts. We describe a case using a superficial femoral artery (SFA) interposition graft to repair the CCA and review the available literature, highlighting the feasibility of this technique for carotid artery reconstruction.

CASE DESCRIPTION: A patient aged 51 years presented with a ruptured mycotic CCA pseudoaneurysm that developed in the setting of a pharyngeal-carotid fistula. Because of the presence of a pharyngeal-carotid fistula and active infection within the vessel wall, endovascular treatment of the pseudoaneurysm was not feasible, and open surgical correction was required to repair the fistulous connection. Furthermore, owing to the extensive soft tissue infection, the use of a synthetic or venous autograft conduit for repair of the artery was contraindicated. Therefore, we harvested a segment of the SFA and used it as an interposition graft to reconstruct the diseased CCA, achieving an excellent anatomic and clinical result.

CONCLUSIONS: This case highlights the feasibility of using an SFA interposition graft for short-segment CCA reconstruction, which can provide significant utility in the setting of a hostile operative field due to prior infection or radiation.
