Pathogenesis of Cerebral Air Embolism during Neodymium-YAG Laser Photoresection: Discussion

Although the “acute carcinoid syndrome” has been previously reported during flexible fiberoptic bronchoscopy in a patient with an endobronchial carcinoid and was also a clinical consideration in our patient, this cause appears unlikely. Serotonin is reported to cause hypertension in the carcinoid syndrome, whereas hypotension has been attributed to the effects of bradykinin, histamine, and […]

Pathogenesis of Cerebral Air Embolism during Neodymium-YAG Laser Photoresection: Hyperbaric treatments

The patient was given dexamethasone (Decadron), 20 mg IVP, and 250 ml of 5 percent albumisol, while a GE-9800 head CT scan, performed without contrast material, was found to be unremarkable. A two-dimensional cardiac echocardiogram showed no thrombus or valvular lesions. A presumed diagnosis of acute air embolism was made. The patient was transferred via […]

Pathogenesis of Cerebral Air Embolism during Neodymium-YAG Laser Photoresection: Course

On the second postoperative day, fiberoptic bronchoscopic study was performed and demonstrated a large, hyperemic endobronchial lesion totally occluding the LLL bronchus. All obtained biopsy specimens were nondiagnostic. A lobectomy was deemed hazardous owing to the recent empyema and risk of developing a stump infection. The patient was therefore transferred to our institution for photoresection […]

Pathogenesis of Cerebral Air Embolism during Neodymium-YAG Laser Photoresection

The phenomenon of arterial air embolism has been described as a sequela to major thoracic trauma, diving accidents, selective arterial angiography, and central venous catheter malfunctions. Recently, arterial air embolism has been reported as a consequence of transthoracic needle lung aspiration. In addition, the occurrence of cerebral air embolism has been reported with transbronchial lung […]
