ABSTRACT
A 45-year-old man with multiple symmetric lipomatosis suffered recurrent syncope attributed to carotid sinus syndrome caused by extrinsic compression of the carotid body by the lipomatous masses. Surgical removal reduced but did not stop syncope, which was then controlled by implantation of a DDD pacemaker.

The electroencephalographic changes of 12 patients submitted to anaesthesia with low dosages of propofol (4-2 mg/kg/h + fentanyl) for peripheral vascular surgery have been studied. The standard induction dose of propofol was 2 mg/kg for all the patients. The EEG recording was carried out during the whole length of anaesthesia and the EEG changes were analysed during induction and maintenance phases. During surgical anaesthesia it was always easy to read EEG and also to detect eventual cerebral suffering. On the basis of our results we can suggest this anesthesiologic technique for surgery (for example: carotid surgery) requiring a continuous monitoring of the cerebral function during intra and postoperative phases.
