The frequency of air embolism was studied in 21 patients during total hip replacement. Two groups were examined, one having femoral shaft cement insertion by hand, the other by Exeter cement gun. Venous air embolism was common throughout the hip surgery, but was especially so during prosthesis positioning in the femoral shaft. There were fewer air emboli and cardiovascular sequelae detected in ...

Quantitative evaluation of shear stress in the vessel wall due to the presence of asymptomatic gas emboli is lacking. The goal of this work was to assess the impact of chronic asymptomatic gas emboli on the risk of atherosclerosis through a custom-built cardiovascular flow simulator. Gas bubbles were created by forced air from a syringe pump. The influences of embolism injection rate, pulse rat...

Gas emboli, including venous and arterial, are a rare but important complication of pediatric cardiac surgery. They have the potential to have devastating consequences and require prompt recognition and treatment. We present a case of gas embolism occurring in the immediate postoperative period in an infant with cyanotic congenital heart disease after palliative cardiac surgery resulting in car...

We report 3 cases of significant foam formation in the venous reservoir with the Maquet Quadrox-I oxygenator and VHK 31 000 reservoir system. All the 3 patients required maximal suction return during procedures, causing pressurization of reservoir and foam formation. Two patients experienced systemic air emboli, which were dealt with by means of retrograde cerebral perfusion and hypothermia wit...

Cetaceans have long been considered capable of limiting diving-induced nitrogen absorption and subsequent decompression sickness through a series of behavioral, anatomical, and physiological adaptations. Recent studies however suggest that in some situations these adaptive mechanisms might be overcome, resulting in lethal and sublethal injuries. Perhaps most relevant to this discussion is the f...

Introduction The inadvertent or purposeful introduction of foreign bodies or substances can lead to cerebral infarction if they embolize to the brain. Individual reports of these events are uncommon but may increase with the increased occurrences of their risk factors, for example, intra-arterial procedures. Method We searched EMBASE and MEDLINE for articles on embolic stroke of nontissue ori...

postoperative visual loss in a patient undergoing hip arthroscopy in the supine position: a case report [1].” Thank you for reporting this complication, which is the first of its kind in hip arthroscopy. We have the following observations. Paradoxical air embolism is certainly a possibility and has been reported after shoulder arthroscopic procedures in the sitting posture, but we feel that sep...

BACKGROUND Fat embolism to the pulmonary circulation is known to occur during total hip arthroplasty, especially during insertion of a cemented femoral component. Fat and air bubbles may enter the systemic circulation via a patent foramen ovale or through pulmonary circulation. METHODS To determine whether microemboli to the brain were occurring during total hip arthroplasty, 23 patients unde...
