Delayed Cerebral Ischemia following to Repair of Penetrating Trauma to External Carotid artery release_rev_09274911-d4b5-4005-8d10-fde4b4da3dab

Abstract

Introduction: Penetrating trauma to anterior neck can induce cerebral ischemia due to carotid artery injury. Brain ischemia also can present after surgical carotid repairs. Early diagnosis and suitable treatment modality prevent from permanent neurologic deficit post operatively. Case Report: A 30 years old man with stab wound to zone two left side of neck underwent exploration and penrose insertion. Due to excessive bleeding through drain tube, patient was transferred to Besat Hospital of Hamadan. Surgical repair of external carotid artery successfully was done. Four days later patient developed right hemiparesis suddenly. According to MRI and color Doppler sonography finding of thrombosis of left common and internal carotid artery, reoperation was done. After thrombectomy cerebral ischemia and hemi-paralysis improved. Conclusions: Surgical approach to symptomatic penetrating neck trauma is oblique cervical incision, control of bleeding, repair of internal carotid, repair or ligature of external carotid artery base on some factors and preferential repair of internal jugular vein. Meticulous and fine surgical technique for both vascular repair and protection of adjacent normal vessels for avoiding to blunt trauma or compression with retractors is noticeable. Exact postoperative care as repeated clinical examination with goal of early diagnosis of internal carotid artery thrombosis and rapid diagnostic and treatment planning of this complication are important factors for taking of good result in treatment of penetrating trauma to carotid.
