Tracheal Chondrosarcoma Excised With Extracorporeal Circulation

Introduction: Tracheal chondrosarcoma (TCS) is a rare malignancy, with only 19 cases described in the literature to date. Case presentation: Herein, we presented the third-largest TCS with such an airway compromise that neither orotracheal intubation nor jet ventilation or even tracheostomy was possible. So, extracorporeal circulation was needed to excise the tumor in a one-stage procedure. Th...

Prolonged extracorporeal circulation.

Interest in prolonged perfusions has increased pari passu with the possibility of treating the more complicated cardiac deformities. Prolonged perfusions may be of interest also in functional disturbances arising during operations using the heart-lung machine, since it may be difficult to discontinue the perfusion before cardiac function is again satisfactory. Furthermore, the biological change...

Miniaturized Extracorporeal Circulation

New ultrasonic radiation reduces cerebral emboli during extracorporeal circulation.

OBJECTIVE Cardiac surgery is associated with intraoperative cerebral emboli, which can result in postoperative neurological complications. A new ultrasonic transducer (EmBlocker) can be positioned on the ascending aorta and activation of the EmBlocker is expected to divert emboli to the descending aorta, thereby decreasing emboli in the cerebral arteries. In this preliminary animal study, safet...

Clinical study of the cerebral hemodynamics during extracorporeal circulation.

The cerebral circulation was studied on 40 clinical cases which underwent open heart surgery under extracorporeal circulation by the low flow rate-hypothermic-hemodilution technique, by means of Kr85, opthalmoscope, blood gas and pH, and cerebral metabolism. Cerebral blood flow decreased to 65.2 per cent of the control value after the start of extracorporeal bypass, but recovered by the later p...
