Patient: Male, 62Final Diagnosis: Splenic hemorrhageSymptoms: Hypotension • syncopeMedication: —Clinical Procedure: Splenic artery angio-embolizationSpecialty: Critical Care MedicineObjective:Rare diseaseBackground:Snakebite envenoming results from injection of a mixture different toxins following snakebite. Coagulopathy and life-threatening hemorrhage can occur, or venom-induced consumption coagulopathy (VICC). A rare case is presented of spontaneous splenic hemorrhage due to VICC that was successfully treated by non-surgical splenic artery embolization.Case Report:A 62-year-old man was admitted to the emergency department after an episode of dizziness and loss of consciousness following a snakebite. He was transferred to our hospital with hypotension and an abnormal blood coagulation test. On admission, he was hypotensive, with reduced hemoglobin and hematocrit levels, but did not complain of abdominal pain. The occult source of bleeding was identified by abdominal computed tomography (CT) as splenic hemorrhage. Treatment began with the administration of antivenom and blood transfusion. Splenic artery angio-embolization was performed to control the bleeding and was without complication.Conclusions:Snakebite envenoming associated with VICC is a serious and life-threatening condition. Because of the possibility of associated occult bleeding from internal organs or blood vessels, imaging studies should be performed as soon as possible. For patients who are hemodynamically stabilized and have atraumatic hemorrhage from the spleen, non-operative treatment using angio-embolization may be performed with intensive monitoring and follow-up.

Sudden unexpected death in epilepsy (SUDEP) refers to the sudden and unexpected death of an epileptic patient with no other health issues, during normal activity, and for whom no other particular cause of death can be found. The exact cause of SUDEP has not been established yet; however, it is assumed to be caused by multiple organ failure involving the respiratory and cardiovascular systems. Some of the known risk factors are generalized tonic-clonic seizure, frequent epileptic seizure, early onset of epilepsy, long duration of seizure, nocturnal seizure, and combined therapy with antiepileptics. A number of seizure-related cardiac arrhythmia cases have been reported. Arrhythmias are mostly benign tachycardia or bradycardia, and ventricular fibrillation (VF) or asystole is very rare. It is considered that fatal cardiac arrhythmia is a cause of SUDEP. Here, we describe the case of a near-SUDEP patient who was successfully revived without complications by immediate defibrillation with an automated external defibrillator and cardiopulmonary resuscitation, although VF occurred after a convulsive seizure. Based on our experience, when treating a patient with an epileptic seizure, one should always keep in mind the possibility of SUDEP as a seizure-induced emergency situation involving fatal arrhythmia and cardiac arrest, even in young healthy adults.

Rationale: Renal vein pseudoaneurysm after blunt trauma is an extremely rare clinical disease. Different interventions, such as conservative, surgical, and endovascular treatments, can be considered. However, previous studies have not described the optimal treatment strategies for this condition. Furthermore, there is a significant lack of prior case reports and of standardized treatment guidelines for trauma-induced renal vein pseudoaneurysm patients who previously maintained antithrombotic agent. Patient concerns: A 23-year-old female patient visited the emergency department after sustaining blunt injury caused by falling. The patient was diagnosed with multiple limb and rib fractures. A right renal vein pseudoaneurysm was found on abdominal computed tomography scan. Initially, there was no other organ damage, and the patient was hemodynamically stable. Thus, nonsurgical, conservative management was considered. However, the patient's hematocrit and hemoglobin levels decreased, and there was no hemodynamic improvement. The patient required lifelong treatment with aspirin because she previously underwent Fontan surgery, and orthopedic surgery for multiple fractures was planned. Thus, considering these factors, the treatment method was changed from conservative management to endovascular stent insertion. Diagnoses: Abdominal computed tomography and renal venography revealed a right renal vein pseudoaneurysm. Interventions: On the basis of the abdominal computed tomography scan and renal venography findings, the endovascular stent graft was inserted across the pseudoaneurysm area. Outcomes: Upon placement of the endovascular stent, hemoglobin and hematocrit levels gradually returned to normal. The patient's vital signs and general condition had improved. The patient recovered without any complications and was discharged 29 days after hospitalization. Lessons: Some patients with traumatic renal vein pseudoaneurysm do not experience hemodynamic improvement despite conservative treatment. Hence, endovascular procedure may be considered for these patients, particularly those who require antithrombotic treatment for a previous disease.

Introduction: Although cardiopulmonary resuscitation is an emergency life-saving procedure, the intervention itself can cause major and often fatal injuries, with diaphragmatic rupture being very rare. This report describes a patient who experienced bilateral pneumothoraces, left diaphragmatic rupture, and pneumoperitoneum after extended cardiopulmonary resuscitation. Case presentation: A 90-year-old woman experienced a cardiac arrest. Spontaneous circulation was restored after 49 min of cardiopulmonary resuscitation performed by a bystander, emergency medical service providers, and emergency department staff. Imaging showed bilateral pneumothoraces, left diaphragmatic rupture, and massive pneumoperitoneum. The patient’s guardian refused to permit surgery for the diaphragmatic rupture, and the patient died despite chest and abdominal decompression and post-cardiac arrest care. Discussion and conclusion: Procedures to restore spontaneous circulation in patients experiencing cardiac arrest may result in fatal cardiopulmonary resuscitation–related injuries. Clinicians providing post-cardiac arrest care should plan management for these iatrogenic injuries.
