Abstract
Introduction Cerebral gas embolism is an unusual but extremely serious condition that occurs when air is introduced into the arterial or venous circulation of the brain. Although rare, it can lead to significant neurological deficits and even the death of the patient. Clinical Case 76-year-old patient with pre-existing diffuse interstitial lung disease, who experienced a massive stroke due to spontaneous pneumomediastinum. Her presentation included confusion, seizures, and motor weakness. Imaging tests revealed air bubbles in the cerebral sulci and hypodense areas in the cerebellum and parietooccipitals. In addition, pneumothorax and air in the upper mediastinum were noted on chest radiographs and chest CT scan. Despite therapeutic measures such as hyperbaric oxygen, the patient unfortunately died due to multiple organ failure. Discussion The diagnosis of cerebral gas embolism generally involves performing a cerebral computed tomography, which is highly sensitive for detecting the presence of air in the cerebral vessels. Management includes monitoring of vital and neurological signs, as well as specific measures such as airway closure, venous catheter aspiration, Trendelenburg positioning, and hyperbaric oxygen. Conclusion Cerebral gas embolism is a potentially fatal condition that requires a brain computed tomography for diagnosis and it is vitally important to know the prevention measures to avoid the appearance of this complication and also to know the general measures to adopt when it occurs.

Abstract
BACKGROUND Air embolization is usually an iatrogenic complication that can occur in both veins and arteries. Intravenous air embolization is mainly associated with large central vein catheters and mechanical ventilation. A 59-year-old woman was sent to our hospital with spontaneous cerebral hemorrhage and treated conservatively with a left forearm peripheral venous catheter infusion drug. After 48 hours, the patient's oxygen saturation decreased to 92 % with snoring breathing. Computer tomography of the head and chest revealed scattered gas in the right subclavian, the right edge of the sternum, the superior vena cava, and the leading edge of the heart shadow. METHODS She was sent to the intensive care unit for high-flow oxygen inhalation and left-side reclining instantly. As the patient was at an acute stage of cerebral hemorrhage and did not take the Trendelenburg position. RESULTS The computed tomography (CT) scan after 24 hours shows that the air embolism subsides. CONCLUSION SUBSECTIONS Air embolism can occur in any clinical scenario, suggesting that medical staff should enhance the ability to identify and deal with air embolism. For similar cases in clinical practice, air embolism can be considered.

Abstract
BACKGROUND Esophagogastroduodenoscopy (EGD) is vital for the diagnosis and treatment of various gastrointestinal conditions but carries a low risk of venous air embolism (VAE). We report a case of VAE during EGD, confirmed by computed tomographic pulmonary angiography (CTPA). CASE A 56-year-old male with a history of hypopharyngeal cancer underwent EGD for dysphagia-related esophageal dilation. Signs of VAE were noted, prompting swift interventions, including oxygen therapy, positional changes, and CTPA. CTPA revealed the Mercedes-Benz sign, pneumomediastinum, and a minimal pneumothorax. The patient's oxygen saturation improved within 30 min before undergoing CTPA, and he was discharged on postoperative day 4. CONCLUSIONS Timely recognition of VAE, resulting in appropriate interventions supported by CTPA, resulted in favorable patient outcomes.

Abstract
Introduction Hyperbaric oxygen treatment (HBOT) is recommended for arterial gas embolism (AGE) with severe symptoms. However, once symptoms subside, there may be a dilemma to treat or not. Case presentation A 71-year-old man was noted to have a mass shadow in his left lung, and a transbronchial biopsy was performed with sedation. Flumazenil was intravenously administered at the end of the procedure. However, the patient remained comatose and developed bradycardia, hypotension, and ST-segment elevation in lead II. Although the ST changes spontaneously resolved, the patient had prolonged disorientation. Whole- body computed tomography revealed several black rounded lucencies in the left ventricle and brain, confirming AGE. The patient received oxygen and remained supine. His neurological symptoms gradually improved but worsened again, necessitating HBOT. HBOT was performed seven times, after which neurological symptoms resolved almost completely. Conclusions AGE can secondarily deteriorate after symptoms have subsided. We recommend that HBOT be performed promptly once severe symptoms appear, even if they resolve spontaneously.

Abstract
Decompression illness is a collective term for two maladies (decompression sickness [DCS] and arterial gas embolism [AGE]) that may arise during or after surfacing from compressed gas diving. Bubbles are the presumed primary vector of injury in both disorders, but the respective sources of bubbles are distinct. In DCS bubbles form primarily from inert gas that becomes dissolved in tissues over the course of a compressed gas dive. During and after ascent ('decompression'), if the pressure of this dissolved gas exceeds ambient pressure small bubbles may form in the extravascular space or in tissue blood vessels, thereafter passing into the venous circulation. In AGE, if compressed gas is trapped in the lungs during ascent, pulmonary barotrauma may introduce bubbles directly into the pulmonary veins and thence to the systemic arterial circulation. In both settings, bubbles may provoke ischaemic, inflammatory, and mechanical injury to tissues and their associated microcirculation. While AGE typically presents with stroke-like manifestations referrable to cerebral involvement, DCS can affect many organs including the brain, spinal cord, inner ear, musculoskeletal tissue, cardiopulmonary system and skin, and potential symptoms are protean in both nature and severity. This comprehensive overview addresses the pathophysiology, manifestations, prevention and treatment of both disorders.

Abstract
Goldenhar syndrome, a rare congenital anomaly, manifests as craniofacial malformations often necessitating intricate surgical interventions. These procedures, though crucial, can expose patients to diverse postoperative complications, including hemorrhage or infection. A noteworthy complication is stroke, potentially linked to air embolism or local surgical trauma. We highlight a case of a male patient, aged 20 years, who experienced a significant postoperative complication of an ischemic stroke, theorized to be due to an air embolism, after undergoing orthognathic procedures for Goldenhar syndrome. The patient was subjected to LeFort I maxillary osteotomy, bilateral sagittal split ramus osteotomy of the mandible, and anterior iliac crest bone grafting to the right maxilla. He suffered an acute ischemic stroke in the left thalamus post-surgery, theorized to stem from an air embolism. Advanced imaging demonstrated air pockets within the cavernous sinus, a rare and concerning finding suggestive of potential air embolism. This case underscores the intricate challenges in treating Goldenhar syndrome patients and the rare but significant risk of stroke due to air embolism or surgical trauma. Limited literature on managing air embolism complications specific to Goldenhar syndrome surgeries exists. Generally, management includes immediate recognition, positional adjustments, air aspiration via central venous catheters, hyperbaric oxygen therapy, hemodynamic support, and high-flow oxygen administration to expedite air resorption. Our patient was conservatively managed post-surgery, and at a 3-month neurology follow-up, he showed significant improvement with only residual right arm weakness. It emphasizes the imperative of a comprehensive, multidisciplinary approach.

Abstract
BACKGROUND Intracardiac thrombus and vascular air embolism represent rare complications in the context of orthotopic liver transplantation. While isolated reports exist for intracardiac thrombus and vascular air embolism during orthotopic liver transplantation, this report presents the first documentation of their simultaneous occurrence in this surgical setting. CASE PRESENTATION This case report outlines the clinical course of a 60-year-old white female patient with end-stage liver disease complicated by portal hypertension, ascites, and hepatocellular carcinoma. The patient underwent orthotopic liver transplantation and encountered concurrent intraoperative complications involving intracardiac thrombus and vascular air embolism. Transesophageal echocardiography revealed the presence of air in the left ventricle and a thrombus in the right atrium and ventricle. Successful management ensued, incorporating hemodynamic support, anticoagulation, and thrombolytic therapy, culminating in the patient's discharge after a week. CONCLUSIONS This report highlights the potential for simultaneous intraoperative complications during orthotopic liver transplantation, manifesting at any phase of the surgery. It underscores the critical importance of vigilant monitoring throughout orthotopic liver transplantation to promptly identify and effectively address these rare yet potentially catastrophic complications.

Abstract
3d Reconnaissance Battalion, a forward-deployed Marine Corps unit in Okinawa, Japan, frequently performs diving operations. Often throughout the year, several reconnaissance teams are diving simultaneously in different locations for training. We present a case of an otherwise healthy 30-year-old-male Reconnaissance Marine who surfaced from a dive with abnormal symptoms and received prompt care from exercise participants who were nonmedical personnel. Studies have demonstrated improved morbidity outcomes in decompression illness patients with shorter times to hyperbaric treatment following the onset of symptoms. High-risk military exercises with diving components have a mandatory safety structure that includes recompression chamber support. All United States Marine Corps Reconnaissance, Marine Corps Special Operations Command, and U.S. Navy dive operations are required to have at least one diving supervisor. To expand the diving capabilities of the unit, Marines are encouraged to attend training and qualify as diving supervisors. This case study demonstrates the efficacy and importance of training Recon Marines to recognize decompression illness as diving supervisors.

Abstract
A 62-year-old male patient underwent pancreaticoduodenectomy with modified Child reconstruction for distal cholangiocarcinoma. After eight years, a contrast-enhanced computed tomography (CT) revealed a recurrent lesion at the biliojejunal anastomosis, and a biliary stent was placed for obstructive cholangitis in the right posterior segment of the liver. A right hepatectomy was planned for a local recurrent lesion;thus, percutaneous transhepatic portal embolization was performed on the portal vein's right branch to enlarge the left liver. However, he was referred to our department for endoscopic retrograde biliary drainage for the subsequent cholangitis and liver abscess appearance. A double-balloon enteroscope under CO2 insufflation was used to reach the bile duct-jejunal anastomosis. After removing the bile duct stent with grasping forceps, his general condition suddenly deteriorated, causing cardiopulmonary arrest. He was diagnosed with air embolism based on the findings of air in the heart, aorta, and brain on CT after the return of spontaneous circulation. Treatment for the air embolism and subsequent complications continued in the intensive care unit, but he eventually died 114 days after the onset of the air embolism due to his deteriorating general condition. Pathological autopsy revealed cholangiocarcinoma that extends from the porta hepatis to the posterior segment. Additionally, the proximity between the bile duct and vein extended by the adenocarcinoma and the fibrous obstruction of the vein were revealed, indicating the possibility of a bile duct-vein shunt.

Abstract
We report the case of a 23-year-old male novice diver who sustained cerebral arterial gas embolism (CAGE) during his open water certification training whilst practising a free ascent as part of the course. He developed immediate but transient neurological symptoms that had resolved on arrival to hospital. Radiological imaging of his chest showed small bilateral pneumothoraces, pneumopericardium and pneumomediastinum. In view of this he was treated with high flow normobaric oxygen rather than recompression, because of the risk of development of tension pneumothorax upon chamber decompression. There was no relapse of his neurological symptoms with this regimen. The utility and safety of free ascent training for recreational divers is discussed, as is whether a pneumothorax should be vented prior to recompression, as well as return to diving following pulmonary barotrauma.

Abstract
Cerebral air embolism (CAE) is a rare, yet potentially devastating condition characterized by entrance of air into cerebral vasculature, that is nearly always iatrogenic. While many findings of CAE are subclinical and incidental at computed tomography (CT), there remain cases of catastrophic and fatal embolisms. Increasing physician awareness of prevention, presentation, and treatment for CAE is crucial for reducing morbidity and mortality. In this case series, we highlight this preventable entity by comparing three cases of CAE that showcase a diverse array of presentations, radiologic findings, and clinical outcomes. We will also explore predisposing factors, prognostic predictors, diagnostic considerations, and available treatments.

Abstract
BACKGROUND Iatrogenic gas embolism is the presence of gas in vascular structures. Feared are those in coronary or cerebral arteries. These can result in cerebral or myocardial infarction. CASE DESCRIPTION A 79-year-old female underwent CT-guided biopsy of the lung. Minutes later she developed neurological symptoms. After administration of oxygen her symptoms initially improved, but later worsened. Based on her symptoms air embolism was suspected. She recovered fully after treatment with hyperbaric oxygen. CONCLUSION Air embolism is a potentially life-threatening complication of surgical, radiological or vascular interventions. Early recognition can lead to prompt treatment and better prognosis. If air embolism is suspected the patient should be treated according to ABCDE principles and oxygen should be administered. In case of neurological or circulatory symptoms a hospital that could provide hyperbaric oxygen therapy should be contacted as soon as possible.

Abstract
Iatrogenic vascular air embolism is a relatively infrequent event but is associated with significant morbidity and mortality. These emboli can arise in many clinical settings such as neurosurgery, cardiac surgery, and liver transplantation, but more recently, endoscopy, hemodialysis, thoracentesis, tissue biopsy, angiography, and central and peripheral venous access and removal have overtaken surgery and trauma as significant causes of vascular air embolism. The true incidence may be greater since many of these air emboli are asymptomatic and frequently go undiagnosed or unreported. Due to the rarity of vascular air embolism and because of the many manifestations, diagnoses can be difficult and require immediate therapeutic intervention. An iatrogenic air embolism can result in both venous and arterial emboli whose anatomic locations dictate the clinical course. Most clinically significant iatrogenic air emboli are caused by arterial obstruction of small vessels because the pulmonary gas exchange filters the more frequent, smaller volume bubbles that gain access to the venous circulation. However, there is a subset of patients with venous air emboli caused by larger volumes of air who present with more protean manifestations. There have been significant gains in the understanding of the interactions of fluid dynamics, hemostasis, and inflammation caused by air emboli due to in vitro and in vivo studies on flow dynamics of bubbles in small vessels. Intensive research regarding the thromboinflammatory changes at the level of the endothelium has been described recently. The obstruction of vessels by air emboli causes immediate pathoanatomic and immunologic and thromboinflammatory responses at the level of the endothelium. In this review, we describe those immunologic and thromboinflammatory responses at the level of the endothelium as well as evaluate traditional and novel forms of therapy for this rare and often unrecognized clinical condition.

Abstract
RATIONALE One of the catastrophic complications of surgical hysteroscopy is venous gas embolism (VGE), and this event could cause morbidity and in serious cases may even lead to death. However, in cases of VGE accompanied by refractory hypokalemia is rare and can significantly increase the difficulty of treatment and resuscitation. Here, we successfully treated a patient with fatal VGE during surgical hysteroscopy, accompanied by difficult resuscitation with refractory hypokalemia. PATIENT CONCERNS We report a rare case of sudden cardiac arrest due to VGE during surgical hysteroscopy, followed by difficult resuscitation with refractory hypokalemia. DIAGNOSIS VGE was diagnosed by a sudden decrease in EtCO2, a loud mill wheel murmur in the thoracic area, and a small number of air bubbles evacuated from the internal jugular catheter. And refractory hypokalemia was diagnosed by serum potassium levels dropping frequently to as low as 2.0 mmol/L within 36 hours of resuscitation after cardiac arrest. INTERVENTIONS Our vigilant anesthesiologist noticed the early sign of VGE with a sudden drop in EtCO2, and as the cardiac arrest occurred, interventional maneuvers were implemented quickly including termination of the surgical procedure, adjustment of the patient's position, cardiac resuscitation, continuous chest compression, and correction of electrolyte disturbances, particularly refractory hypokalemia during the early stage of resuscitation. OUTCOMES The patient regained consciousness 4 days after the cardiac arrest and was discharged 1 month later without any neurological deficits. LESSONS As a relatively simple procedure, surgical hysteroscopy may have catastrophic complications. This case demonstrates the full course of fatal gas embolism and difficult resuscitation during hysteroscopic surgery, and emphasizes the importance of early detection, prompt intervention, and timely correction of electrolyte disturbances, such as refractory hypokalemia.

Abstract
OBJECTIVE To report a case of systemic gas embolism associated with removal of a chest drain perforating a lung lobe in a dog undergoing sternotomy under general anesthesia and intermittent positive pressure ventilation. CASE SUMMARY An 8-year-old Cocker Spaniel underwent an exploratory thoracotomy via median sternotomy for surgical management of pyothorax that was treated conservatively for 7 days prior to referral following bilateral chest drain placement. The surgical procedure consisted of a subphrenic mediastinectomy and pericardiectomy. During surgery, it became apparent that the right drain was perforating the right middle lung lobe. Sudden desaturation and rapid hemodynamic deterioration occurred after the drain was removed. A systemic gas embolism was suspected on the basis of clinical signs and results of an arterial blood gas analysis, and immediate supportive treatment was started with an adequate response. Once the surgical procedure was completed, a clear "mill wheel" sound was audible on cardiac auscultation and point-of-care cardiac ultrasound confirmed the presence of gas bubbles in the cardiac chambers. The dog recovered from anesthesia and was managed in the intensive care unit where arterial blood gas analyses were nearly normal and the dog made a full recovery. NEW OR UNIQUE INFORMATION PROVIDED In people, there are reports of fatal air embolism related to the use of chest drains. To our knowledge, this is the first case report in dogs of a systemic gas embolism during open-chest surgery caused by a chest drain perforating a lung lobe. Immediate recognition and aggressive treatment of this life-threatening condition should be provided in order to achieve a favorable outcome.

Abstract
Venous air embolism (VAE) occurs when air is introduced into the venous system and subsequently travels into the right heart and pulmonary circulation. VAE mainly occurs from air that is forced by positive pressure or drawn in by negative pressure. We present a rare case of fatal VAE that occurred during a routine dental root canal procedure. A 69-year-old male was undergoing a root canal procedure at an outpatient dental office under local anesthesia. During the procedure, he went into cardiopulmonary arrest. He was resuscitated, and return of spontaneous circulation was achieved. Thoracic computed tomography was performed and revealed large amounts of air within the right ventricle and portal venous system. VAE should be recognized as a potentially fatal complication resulting from routine dental procedures.

Abstract
Gas embolism is a procedure-related complication and has been reported during endoscopy, surgical procedures, intravenous catheterization, positive pressure ventilation, and a multitude of scenarios. Recognizing the potential for gas embolus and a high level of suspicion are paramount to timely intervention to prevent significant morbidity and mortality. There is such rapid decompensation that only clinical suspicion can guide timely intervention; it is not uncommon for gas embolus to be diagnosed postmortem. It then must be determined whether the gas embolus has a venous or systemic entry point. Overall management is similar for both forms of gas emboli with focus on hemodynamic support and preservation of organ function. This case report discusses an occurrence of presumed systemic gas embolus from argon plasma coagulation and management of a patient under general anesthesia during rigid bronchoscopy.
