Management strategy of a carotid-esophageal fistula with a right common carotid artery pseudoaneurysm due to chicken bone ingestion: A case report and literature review.

Common carotid artery (CCA) pseudoaneurysm is a rare clinical disorder. CCA pseudoaneurysm that occurs with a carotid-esophageal fistula and causes massive upper gastrointestinal bleeding is especially uncommon but can be life-threatening. Accurate diagnosis and prompt managements are essential to save lives. Here, we report a case of a 58-year-old female who presented with dysphagia and throat pain after accidental ingestion of a chicken bone. The patient presented with active upper gastrointestinal bleeding which quickly developed into hemorrhage shock. Imaging studies confirmed a diagnosis of right CCA pseudoaneurysm and carotid-esophageal fistula. The patient had a satisfactory recovery after a right CCA balloon occlusion, right CCA pseudoaneurysm excision, and right CCA and esophageal repairs. We present and discuss this case here to remind physicians to rule out rare causes of upper gastrointestinal bleeding. A multidisciplinary approach is commonly required to achieve satisfactory outcomes in these cases.

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

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.
