Sudden cardiac arrest during endovascular embolization of carotid artery aneurysm: A case report and literature review

Rationale: Endovascular embolization has been widely applied in carotid artery aneurysm due to less trauma and simpler procedures than open surgery. Sudden cardiac arrest is a rare event that may cause severe consequences during endovascular embolization. Risk factors of perioperative cardiac arrest include cardiac surgery, younger age, comorbid conditions, and emergency surgery. Patient concerns: A 62-year-old male patient had hypertension for 15 years and experienced sudden cardiac arrest of pulseless electrical activity during endovascular embolization. Diagnoses: He was diagnosed with a 3.5 x 2.5 mm aneurysm. Interventions: Chest compression and effective interventions were given. Outcomes: He was resuscitated by cardiopulmonary resuscitation and systematic therapy. Lessons: This case may provide experience in the management of sudden cardiac arrest during endovascular embolization of a carotid artery aneurysm.
