Abstract Background Esophageal submucosal hematoma is a rare complication after endovascular surgery. We report a case of an esophageal submucosal hematoma which may have been caused by rigorous cough during extubation. Case presentation A 75-year-old woman underwent endovascular treatment for unruptured cerebral aneurysm under general anesthesia. The patient received aspirin and clopidogrel before surgery and heparin during surgery. Activated clotting time was 316 s at the end of surgery. Protamine was not administered and continuous infusion of argatroban was started after surgery. She had a rigorous cough during removal of the tracheal tube and reported retrosternal discomfort postoperatively. She developed hemorrhagic shock after massive hematemesis. A diagnosis of esophageal submucosal hematoma was made by endoscopic examination and computed tomography. Hemostasis was achieved by compression with a Sengstaken-Blakemore tube and endoscopic cauterization. Blood pressure was recovered by blood transfusion. Endoscopic examination performed 7 days after surgery showed that esophageal submucosal hematoma had almost disappeared and slough had adhered to the mucosal laceration. The patient showed good recovery and was discharged 21 days after surgery. Conclusions Careful extubation and postoperative observation are required in patients receiving antiplatelet and anticoagulant therapy.
