The recent development of less invasive intracardiac surgery using small incisions and videoscopic techniques allowed an evaluation of the advantages and limitations of this new approach. Among the limitations was the increased difficulty of the surgical technique when using long instruments through small incisions and ports. We investigated whether(More)
OBJECTIVE The development of endoscopic coronary artery bypass grafting has been limited because of poor visualization and increased technical difficulties in carrying out operations through ports. We investigated whether the use of robotic assisted instruments could minimize these difficulties. METHODS After a period of technical development and training(More)
Vasopressin- and oxytocin-immunoreactive cells have been demonstrated in the brain of the leech Theromyzon tessulatum. A mapping of their localization in the different compartments of the brain has been undertaken. The cells immunohistochemically identified have been compared to previously described cell types defined by classical staining methods for(More)
Aortic stenosis is known to modify initial upstroke time (IUT) of velocity in peripheral arteries and carotid velocities. The authors conducted a prospective study in 30 patients scheduled for aortic valve replacement for aortic stenosis. The goal was to establish postoperative correction of carotid flow disorders. In the preoperative period, a positive(More)
Pseudoaneurysms of the ascending aorta following previous thoracic surgery pose a difficult surgical management problem. In this report, we present a case of a patient with aortic insufficiency and a pseudoaneurysm of the ascending aorta at the site of a previous anastomosis. The particularity of this case is in the atypical use of Port-Access technology(More)
OBJECTIVE To assess the feasibility of endoscopic telemanipulated cardiac surgery and describe the anesthetic, postoperative, and surgical implications of minimally invasive robotic-assisted cardiac surgery. DESIGN Prospective study. SETTING Cardiovascular and transplant center, university hospital. PARTICIPANTS Twenty patients (13 men, 7 women)(More)
A young woman 38 years of age underwent Doppler ultrasonography following the spontaneous appearance of cervical pain causing loss of sleep. The examination revealed bilateral dissection of the internal carotid arteries, confirmed by supraaortic arteriography. Two successive CT scans showed no cerebral lesions. A thrombosis of the great saphenous vein was(More)
The active material incubated with trypsin, or pronase lost its activity but not with pepsin. The peptide nature of the inhibitory factor is thus determined. Dialysis and gel filtration chromatography of this substance suggest that the inhibitory factor is a small molecule.
Pseudo-aneurysms of the ascending aorta after thoracic surgery are rare and pose a problem of surgical strategy with respect to the approach, the myocardial protection and type of repair. The authors have solved the problem by using a new technology, the Post-Access TM system, which, by simply introducing a catheter into the femoral artery, allows(More)
