Case report: Cardiac arrest after radiofrequency ablation in a 76-year-old male.

RATIONALE: Previous studies have found that the main treatment of sinus arrest is pacemaker treatment. It is rare to have 12 s of sinus arrest after radiofrequency ablation, and whether a permanent pacemaker is implanted immediately in this case is not described in the guidelines. PATIENT CONCERNS: A 76-year-old male patient with persistent atrial fibrillation (AF) developed sinus arrest lasting 12 s in the early morning of the fourth day after using radiofrequency ablation for pulmonary vein isolation. DIAGNOSIS: The patient was diagnosed with AF and sinus arrest. INTERVENTIONS: The patient received cardiopulmonary resuscitation, intravenous injection of atropine 1 mg, and intravenous infusion of isoproterenol 1mg and immediately recovered consciousness thereafter. Approximately, 1.5 h later, the patient underwent surgery to install a temporary pacemaker in the right femoral vein. OUTCOMES: The patient had repeated episodes of sinus arrest after the implantation of a temporary pacemaker. After 3 weeks, the patient stabilized and was discharged. The patient was followed up for 1 year and did not experience any recurrence of sinus arrest or AF. LESSONS: We consider the potential for postoperative myocardial edema, injury to the sinoatrial node during the procedure, propafenone poisoning, and autonomic dysfunction as contributors to the occurrence of sinus arrest after radiofrequency ablation. When sinus arrest occurs after radiofrequency ablation, we can choose the appropriate treatment according to the patient's condition.

Chylopericardium following esophagectomy: a case report and systematic review.

BACKGROUND: Chylopericardium is a rare condition characterized by the accumulation of chyle in the pericardial space. It is most commonly caused by thoracic duct injury. Chylopericardium following esophagectomy is extremely rare but can cause life-threatening complications. This report presents a case of chylopericardium post-esophagectomy, resulting in cardiac tamponade and cardiac arrest. A systematic literature review was also conducted to facilitate the understanding of this rare condition. CASE PRESENTATION: A 41-year-old male was admitted to our hospital with intermediate to highly differentiated squamous cell carcinoma of the mid-thoracic esophagus (clinical T4NxM0). He underwent thoracoscopic-laparoscopic esophagectomy with cervical anastomosis. On postoperative day 1, patient had a cardiac arrest secondary to cardiac tamponade, requiring emergency ultrasound-guided drainage. The drained fluid was initially serous but became chylous after the administration of enteral nutritional emulsion. As a result of significant daily pericardial drainage, patient subsequently underwent thoracic duct ligation. The amount of drainage was substantially reduced post-thoracic duct ligation. Over a period of 2 years and 7 months, patient recovered well and tolerated full oral diet. A comprehensive literature review was conducted and 4 reported cases were identified. Among these cases, three patients developed pericardial tamponade secondary to chylopericardium post-esophagectomy. CONCLUSION: Chylopericardium is a rare but serious complication post-esophagectomy. Prompt echocardiography and thorough pericardial fluid analysis are crucial for diagnosis. Thoracic duct ligation has been shown to be an effective management approach for this condition.

Simple and secure thrombectomy without circulatory arrest for acute pulmonary embolism.

BACKGROUND: Surgical pulmonary artery thrombectomy is a well-established emergency treatment for massive pulmonary embolism (PE) in which fibrinolysis or thrombolysis are not effective. However, surgery for massive PE that requires peripheral pulmonary artery thrombus removal remains challenging. We established a simple and secure pulmonary artery thrombectomy method using cardiopulmonary bypass and cardiac arrest. In this procedure, the surgical assistant arm, typically used for coronary artery bypass grafting, is used to obtain a feasible working space during thrombectomy. CASE PRESENTATION: We present seven consecutive massive PE cases that were treated with the present surgical method and successfully weaned from cardiopulmonary bypass or extracorporeal membrane oxygenation postoperatively. CONCLUSIONS: This procedure can be used to prevent right ventricular failure after surgery as surgeons can remove the peripheral thrombus with clear vision up to the second branch of the pulmonary artery.

Who benefits from resuscitative thoracotomies following penetrating trauma: The patient or the learner?

BACKGROUND: Resuscitative thoracotomy (RT) is a salvage procedure following traumatic cardiac arrest. We aim to evaluate RT trends and outcomes in adults with cardiac arrest following penetrating trauma to determine the effect on mortality in this population. Further, we aim to estimate the effect of hospital teaching status on the performance of resuscitative thoracotomies and mortality. METHODS: We reviewed the National Trauma Data Bank (2017-2021) for adults (≥16 years old) with penetrating trauma and prehospital cardiac arrest, stratified by the performance of a RT. We performed multivariable logistic regressions to estimate the effect of RT on mortality and the effect of hospital teaching status on the performance of resuscitative thoracotomies and mortality. RESULTS: 13,115 patients met our inclusion criteria. RT occurred in 12.7% (n = 1,664) of patients. Rates of RT trended up over the study period. Crude mortality was similar in RT and Non-RT patients (95.6% vs. 94.5%, p = 0.07). There was no statistically significant difference in the adjusted odds of mortality based on RT status (OR 0.82, 95%CI 0.56-1.21). University-teaching hospitals had an adjusted odds ratio of 1.68 (95% CI 1.31-2.17) for performing a RT than non-teaching hospitals. There was no difference in the adjusted odds of mortality in patients that underwent RT based on hospital teaching status. CONCLUSION: Despite up-trending rates, a resuscitative thoracotomy may not improve mortality in adults with penetrating, traumatic cardiac arrest. University teaching hospitals are nearly twice as likely to perform a RT than non-teaching hospitals, with no subsequent improvement in mortality.

Emergency Cricothyrotomy in a Harsh Environment: A Case Report of Complete Airway Obstruction Following a Lightning Strike.

A lightning strike is an extreme event with the highest mortality rate among electrical injuries. Death from a lightning strike is caused by either cardiac arrest or respiratory arrest. It is rare for upper airway damage to occur, but in these cases, airway control is recommended. If transoral intubation is unsuccessful, an emergency cricothyrotomy should be considered. Our case report describes an emergency cricothyroidotomy performed in a harsh environment on a mountain 2300 m above sea level on a patient with extensive burns of his supraglottic structures, after being directly hit by a lightning strike.

Emergency thoracotomies in traumatic cardiac arrests following blunt trauma - experiences from a German level I trauma center.

PURPOSE: Resuscitative thoracotomies (RT) are the last resort to reduce mortality in patients suffering severe trauma. In recent years, indications for RT have been extended from penetrating to blunt trauma. However, discussions on efficacy are still ongoing, as data on this rarely performed procedure are often scarce. Therefore, this study analyzed RT approaches, intraoperative findings, and clinical outcome measures following RT in patients with cardiac arrest following blunt trauma. METHODS: All patients admitted to our level I trauma center's emergency room (ER) who underwent RT between 2010 and 2021 were retrospectively analyzed. Retrospective chart reviews were performed for clinical data, laboratory values, injuries observed during RT, and surgical procedures. Additionally, autopsy protocols were assessed to describe injury patterns accurately. RESULTS: Fifteen patients were included in this study with a median ISS of 57 (IQR 41-75). The 24-h survival rate was 20%, and the total survival rate was 7%. Three approaches were used to expose the thorax: Anterolateral thoracotomy, clamshell thoracotomy, and sternotomy. A wide variety of injuries were detected, which required complex surgical interventions. These included aortic cross-clamping, myocardial suture repairs, and pulmonary lobe resections. CONCLUSION: Blunt trauma often results in severe injuries in various body regions. Therefore, potential injuries and corresponding surgical interventions must be known when performing RT. However, the chances of survival following RT in traumatic cardiac arrest cases following blunt trauma are small.

Development of a high fidelity, multidisciplinary, crisis simulation model for robotic surgical teams.

Immediate access to the patient in crisis situations, such as cardiac arrest during robotic surgery, can be challenging. We aimed to present a full immersion simulation module to train robotic surgical teams to manage a crisis scenario, enhance teamwork, establish clear lines of communication, improve coordination and speed of response. Start time of cardiopulmonary resuscitation (CPR), first defibrillator shock and robotic de-docking time from the first 'cardiac arrest call' were recorded. Observational Teamwork Assessment for Surgery (OTAS) scores were used in control and test simulations to assess performance along with a participant survey. Repeat scenarios and assessment were conducted at a 6-month interval for the same team to validate knowledge retention and an additional scenario was run with a new anaesthetic team to validate modular design. OTAS scores improved across all specialty teams after training with emergency algorithm and at retention validity re-test (p = 0.0181; p = 0.0063). There was an overall reduction in time to CPR (101-48 s), first defibrillator shock (> 302 s to 86 s) and robot de dock time (86-25 s) Improvement remained constant at retention validity re-test. Replacing the anaesthetic team showed improvement in time to CPR, first shock and robotic de-dock times and did not affect OTAS scores (p = 0.1588). The module was rated highly for realism and crisis training by all teams. This high-fidelity simulation training module is realistic and feasible to deliver. Its modular design allows for efficient assessment and feedback, optimising staff training time and making it a valuable addition to robotic team training.

Surgical Management of Massive Pulmonary Embolism Presenting with Cardiopulmonary Arrest: How Far Is Too Far?

The incidence of diagnosed massive pulmonary embolism presenting to the Emergency Department is between 3% and 4.5% and it is associated with high mortality if not intervened timely. Cardiopulmonary arrest in this subset of patients carries a very poor prognosis, and various treating pathways have been applied with modest rate of success. Systemic thrombolysis is an established first line of treatment, but surgeons are often involved in the decision-making because of the improving surgical pulmonary embolectomy outcomes.

Hybrid surgery for blunt aortic injury with rupture: a case report.

BACKGROUND: Blunt thoracic aortic injury is one of the most lethal traumatic injuries. Ruptured cases often result in cardiac arrest before arrival at the hospital, and survival is rare. CASE PRESENTATION: A female patient in her 30 s was struck by an automobile while she was walking across an intersection. She was in a state of shock when emergency services arrived and was in cardiac arrest shortly after arriving at the hospital. A left anterolateral thoracotomy revealed a massive hemothorax secondary to thoracic aortic rupture. In addition, the patient had multiple traumas, including maxillary, pelvic, and lumbar burst fractures. We attempted to directly suture the aortic lesion; however, the increasing blood pressure caused the suture to break. We used a thoracic stent graft while ensuring permissive hypotension. Her postoperative prognosis was positive, and she was transferred to another hospital 85 days later. CONCLUSIONS: We successfully performed a hybrid surgery combining thoracotomy and endovascular repair for this emergency case of blunt thoracic aortic injury with rupture.

Prehospital Ultrasound Use to Guide Resuscitative Thoracotomy in Blunt Traumatic Cardiac Arrest.

Traumatic cardiac arrest is frequently encountered in the air medical transport environment, and resuscitative thoracotomy is a procedure that is sometimes performed in an attempt to salvage these critically injured patients. Focused assessment with sonography for trauma (FAST) is a point-of-care ultrasound protocol commonly used in trauma patients to detect the presence of free fluid in the intraperitoneal and pericardial spaces. The authors present a case of an adult female victim of a motor vehicle collision whose prehospital FAST scan revealed significant hemoperitoneum without hemopericardium. When she developed cardiac arrest, these ultrasound findings aided in the decision to perform resuscitative thoracotomy and helped guide the sequence of maneuvers with prioritization given to cross-clamping the aorta. This case highlights the utility of prehospital ultrasound in yielding timely, actionable diagnostic information that can inform the performance of a high-acuity low-occurrence procedure in the air medical transport environment.

A Century With Craniopagus Twin Separation Surgeries: Nihilism to Optimism.

Craniopagus conjoined twins are extremely rare, reported 1 in 2.5 million live births. To date, 62 separation attempts in 69 well-documented cases of craniopagus twins have been made. Of these, 34 were performed in a single-stage approach, and 28 were attempted in a multistage approach. One or both twins died of massive intraoperative blood loss and cardiac arrest in 14 cases. We report our surgical experience with conjoined craniopagus twins (JB) with type III total vertical joining and shared circumferential/circular sinus with left-sided dominance. A brief review of the literature is also provided. In our twins, the meticulous preoperative study and planning by the multidisciplinary team consisting of 125-member, first-staged surgical separation consisted of creation of venous conduit to bypass part of shared circumferential sinus and partial hemispheric disconnection. Six weeks later, twin J manifested acute cardiac overload because of one-way fistula development from blocked venous bypass graft necessitating emergency final separation surgery. Unique perioperative issues were abnormal anatomy, hemodynamic sequelae from one-way fistula development after venous bypass graft thrombosis, cardiac arrest after massive venous air embolism requiring prolonged cardiopulmonary resuscitation, and return of spontaneous circulation at 15 minutes immediately after separation. This is the first Indian craniopagus separation surgery in a complex total vertical craniopagus twin reported by a single-center multidisciplinary team. Both twins could be sent home, but one remained severely handicapped. Adequate perioperative planning and multidisciplinary team approach are vital in craniopagus twin separation surgeries.

A life-saving case of cardiopulmonary arrest with cardiac tamponade caused by erosion 6 years after percutaneous atrial septal defect closure: a case report.

BACKGROUND: Cardiac erosion after percutaneous atrial septal defect (ASD) closure is a rare complication that requires immediate life-saving emergency surgery. In this report, we present our successful life-saving strategy for cardiac arrest due to cardiac tamponade caused by erosion 6 years after the percutaneous closure of an ASD. CASE PRESENTATION: The patient was a 50-year-old man who received treatment using an Amplatzer septal occluder (St. Jude Medical, St. Paul, MN, USA) treatment for ostium secundum atrial septal defect (size: 29.5 × 27.0 mm) at another institution when he was 44 years old. CONCLUSIONS: This case report presents a bailout surgical strategy for patients who are hemodynamically unstable with risks of coagulopathy and multiple organ failure. This case shows that cardiac surgeons need to be aware of percutaneous ASD-closure complications and should consider a bailout surgical strategy for patients at risk of multiple organ failure.

Lumbosacral plexopathy due to pelvic hematoma after extracorporeal membrane oxygenation: A case report.

RATIONALE: Peripheral nerve injury related to vascular complications associated with extracorporeal membrane oxygenation (ECMO) is perhaps underappreciated. Compared to the well-described central nervous system complications of ECMO, brachial plexopathy and lumbosacral plexopathy have rarely been reported. We report this case to heighten awareness of lumbosacral plexus injury due to pelvic hematoma formation after ECMO. PATIENT CONCERNS: A 53-year-old woman developed a large pelvic hematoma with significant mass effect on intrapelvic structures after receiving lifesaving venoarterial ECMO for cardiogenic shock following a cardiac arrest. During her hospital course, she developed bilateral foot drop that was attributed to critical illness. Her lack of neurological recovery after 6 months prompted referral to neuromuscular medicine for consultation. DIAGNOSIS: The patient was retrospectively diagnosed with bilateral lumbosacral plexopathy due to the large pelvic hematoma. INTERVENTION: Electromyography/nerve conduction study (EMG/NCS) obtained at the time of referral to neuromuscular medicine localized her neurological deficits to the bilateral lumbosacral plexus and demonstrated no volitional motor unit action potentials in her lower leg muscles. OUTCOMES: The patient had minimal recovery of strength at the level of the ankles but was ambulatory with solid ankle-foot orthoses due to spared proximal lower extremity strength. Unfortunately, the absence of any volitionally activated motor unit action potentials in her lower leg muscles on EMG performed 6 months after the initial injury was a poor prognostic indicator for successful reinnervation and future neurological recovery. LESSONS: Neurological deficits occurring during the course of administration of ECMO require accurate localization. Neurology consultation and/or EMG/NCS may be useful if localization is not clear. Lesions localizing to the lumbosacral plexus should prompt radiographic evaluation with computed tomography of the abdomen and pelvis. Hemostasis of a retroperitoneal hematoma may be achieved with embolization. However, if neurological deficits do not improve, surgical consultation for hematoma evacuation may be warranted.

Impella use in real-world cardiogenic shock patients: Sobering outcomes.

BACKGROUND: Critically ill patients with cardiogenic shock could benefit from ventricular assist device support using the Impella microaxial blood pump. However, recent studies suggested Impella not to improve outcomes. We, therefore, evaluated outcomes and predictors in a real-world scenario. METHODS: In this retrospective single-center trial, 125 patients suffering from cardiac arrest/cardiogenic shock between 2008 and 2018 were analyzed. 93 Patients had a prior successful cardiopulmonary resuscitation. The primary endpoint was hospital mortality. Associations of covariates with the primary endpoint were assessed by univariable and multivariable logistic regression. Adjusted odds ratios (aOR) and optimal cut-offs (using Youden index) were obtained. RESULTS: Hospital mortality was high (81%). Baseline lactate was 4.7mmol/L [IQR = 7.1mmol/L]. In multivariable logistic regression, only age (aOR 1.13 95%CI 1.06-1.20; p<0.001) and lactate (aOR 1.23 95%CI 1.004-1.516; p = 0.046) were associated with hospital mortality, and the respective optimal cut-offs were >3.3mmol/L and age >66 years. Patients were retrospectively stratified into three risk groups: Patients aged ≤66 years and lactate ≤3.3mmol (low-risk; n = 22); patients aged >66 years or lactate >3.3mmol/L (medium-risk; n = 52); and patients both aged >66 years and lactate >3.3mmol/L (high-risk, n = 51). Risk of death increased from 41% in the low-risk group, to 79% in the medium risk group and 100% in the high-risk group. The predictive abilities of this model were high (AUC 0.84; 95% 0.77-0.92). CONCLUSION: Mortality was high in this real-world collective of severely ill cardiogenic shock patients. Better patient selection is warranted to avoid unethical use of Impella. Age and lactate might help to improve patient selection.

Safe Lung Flush Technique During Recovery From Donors After Circulatory Death.

Donation after circulatory death is defined as donation after cardiac arrest and circulatory cessation. The number of circulatory death donors is growing and significantly increases the organ donor pool. Shortening the warm ischemia time is pivotal in the outcomes and survival after transplant. We describe simplified and safe technique for lung flush during lung recovery from donors after circulatory death.

Emergency Department Resuscitative Thoracotomy: Indications, surgical procedure and outcome. A narrative review.

BACKGROUND: Emergency Department Thoracotomy (EDRT) after traumatic Cardio-pulmonary Arrest (CPR) can be used to salvage select critically injured patients. Indications of this surgical procedure are widely debated and changed during last decades. We provide the available literature about EDRT in the effort to provide a comprehensive synthesis about the procedure, likelihood of success and patient's outcome in the different clinical setting, accepted indications and technical details adopted during the procedure for different trauma injuries. METHODS: Literature from 1975 to 2020 was retrieved from multiple databases and reviewed. Indications, contraindications, total number and outcome of patients submitted to EDRT were primary endpoints. RESULTS: A total number of 7236 patients received EDRT, but only 7.8% survived. Penetrating trauma and witnessed cardiopulmonary arrest with the presence of vital signs at the trauma center are the most favorable conditions to perform EDRT. CONCLUSIONS: EDRT should be reserved for acute resuscitation of selected dying trauma patient. Risks of futility, costs, benefits of the surgical procedure should be carefully evaluated before performing the surgical procedure.
