BACKGROUND: The cross-sectional area of the subclavian vein (csSCV) is an important factor determining the success rate of SCV catheterization. The head-down position increases the csSCV. However, the effects of lateral tilting on subclavian venous cross-sectional area have not yet been explored. In this trial, we test our hypothesis that ipsilateral tilt during right SCV catheterization may significantly increase the csSCV by impeding blood flow to the heart, thereby increasing the primary venipuncture success rate and reducing the complication rate and procedure time...

A case with cerebral venous air embolism (CVAE) after neurosurgery and treated with hyperbaric oxygen therapy (HBOT) is presented. This is a rare and potentially fatal complication that neurosurgeons should be aware of. A 52-year-old male was diagnosed with an intracerebral hematoma. An emergency evacuation of the hematoma was performed with a craniotomy and the postoperative CT scan showed a complete evacuation of the hematoma, but it also revealed a CVAE. The patient was immediately referred to HBOT and received three sessions within 48 h...

Neuroendoscopic procedures are increasingly performed nowadays due to the significant technological improvement of endoscopic instrumentation. It carries various advantages such as speed, simplicity, avoidance of implants, and no brain dissection or retraction. Although considered to be safe, it is associated with a host of complications. We hereby report a case of venous air embolism in an infant who was undergoing endoscopic third ventriculostomy. The complication occurred at the completion of surgery when surgeons were withdrawing the endoscope...

Venous air embolism can be a catastrophic iatrogenic complication during operative hysteroscopy and makes this simple surgical procedure very risky, especially with the lack of knowledge about its prevention, presentation, and immediate management. Three out of 13 hysteroscopic myoma resections at our center had venous gas embolism (VGE). The prevention, diagnosis, and management of VGE are described in this report of three cases.

Fifty-four year-old man with recent history of myocardial infarction and a percutaneous coronary intervention who suffered a ventricular fibrillation arrest at home. He was resuscitated in the field. His heart rhythm was in atrial fibrillation. The cardiac catheterization showed a patent stent from his previous myocardial infarction and no new occlusions. He subsequently underwent hypothermia protocol using the Alsius CoolGard 3000 Temperature Control System and Icy Catheter. Heparin drip was started for atrial fibrillation 36 hours after catheter insertion and became therapeutic 2 hours before the end of cooling maintenance phase...

BACKGROUND: The sitting position has lost favor among neurosurgeons partly owing to assumptions of increased complications, such as venous air embolisms and hemodynamic disturbances. Moreover, the surgeon must assume a tiring posture. We describe our protocol for the "praying position" for pineal region surgery; this variant may reduce some of the risks of the sitting position, while providing a more ergonomic surgical position. METHODS: A retrospective review of 56 pineal lesions operated on using the praying position between January 2008 and October 2015 was performed...

An abrupt increase in end-tidal CO2 (EtCO2; from 35 to 58 mm Hg) followed by a sudden fall (to 18 mm Hg) was noted during retroperitoneoscopic adrenalectomy under general anaesthesia in a 23-year-old patient with adrenal hyperplasia. This was accompanied by hypotension (systolic blood pressure of 60 mm Hg), desaturation (88% SpO2) and ST depression (3.5 mm). The patient was resuscitated with fluids and vasopressor drugs and about 4 mL of air was aspirated through the central venous catheter, confirming the diagnosis of an intraoperative gas embolism...

BACKGROUND: Sitting position is preferred during posterior fossa surgeries as it provides better anatomical orientation and a clear surgical field. However, its use has been declining due to its propensity to cause life-threatening complications. This study was carried out to analyze the perioperative complications and postoperative course of children who underwent neurosurgery in sitting position. MATERIALS AND METHODS: Medical records of 97 children (<18 years) who underwent neurosurgery in sitting position over a period of 12 years, were retrospectively analyzed...

Primary medullary hemorrhage is a rare event that may result in ataxic respiration. Although it remains controversial whether primary medullary hemorrhage should be managed conservatively or surgically, recent advancements in neuroimaging and microsurgical techniques have shown promise for improving outcomes and prognosis following surgery. The present report discusses the case of a 70-year-old woman admitted to our institution due to sudden-onset nausea and vomiting. The patient underwent surgical removal of a right medullary hematoma for the treatment of daytime respiratory depression and nocturnal apnea while in the half-sitting position...

Cerebral air embolism is a rare clinical entity in day-to-day practice. The introduction of air into the venous or the arterial system can cause cerebral air embolism leading to severe neurological deficits. The common causes reported in the literature are iatrogenic; it can be caused by positive pressure maneuvers performed during cardiac resuscitation, lung biopsy, and the placement of venous catheters in the presence of a patent foramen ovale. We report a case of cerebral air embolism which has occurred secondary to lung laceration...

Cerebral air embolism is caused by gas bubbles in the vascular system. These bubbles can cause cerebral ischemia by obstructing encephalic blood vessels. It is frequently associated with blunt and penetrating chest trauma as well as iatrogenic interventions. Lung trauma involving laceration of the respiratory tract, lung parenchyma, and blood vessels may result in direct communication of these structures, driving air or gas into the pulmonary venous system. We report a case of a blunt chest trauma that led to massive arterial air embolism that was possible to recognize with the help of postmortem computed tomographic scan examination...

BACKGROUND: Thromboelastography (TEG) in venous air embolism (VAE) has been poorly studied. We induced coagulation abnormalities by VAE in a rat model, assessed by TEG with and without mexiletine, a lidocaine analogue local anesthetic. METHODS: Twenty-three Sprague Dawley rats instrumented under isoflurane anesthesia and allowed to recover five days prior to the experiments were randomized into three experimental groups: 1) VAE (n = 6); 2) VAE and mexiletine (n = 9); and 3) normal saline (NS) alone (control group, n = 8)...

Venous air embolism is a dreaded condition particularly relevant to the field of nephrology. In the face of a favourable, air-to-blood pressure gradient and an abnormal communication between the atmosphere and the veins, air entrance into the circulation is common and can bring about venous air embolism. These air emboli can migrate to different areas through three major routes: pulmonary circulation, paradoxical embolism and retrograde ascension to the cerebral venous system. The frequent undesirable outcome of this disease entity, despite timely and aggressive treatment, signifies the importance of understanding the underlying pathophysiological mechanism and of the implementation of various preventive measures...
