We have developed a peripheral nerve catheter, attached to a needle, which works like an adjustable suture. We used in-plane ultrasound guidance to place 45 catheters close to the femoral, saphenous, sciatic and distal tibial nerves in cadaver legs. We displaced catheters after their initial placement and then attempted to return them to their original positions. We used ultrasound to evaluate ...

PURPOSE To report the clinical features of strabismus associated with Graves' orbitopathy, and the results of surgery with adjustable suture under drop anesthesia. METHODS The charts of 13 patients who had surgical treatment for strabismus related to Graves' orbitopathy at Hospital das Clínicas of University of São Paulo were retrospectively reviewed. Ocular motility, sensorial examination an...

PURPOSE Although laparoscopic adjustable gastric banding (LAGB) is a popular bariatric procedure, few comprehensive studies have been investigated on the use of non-gastro-gastric sutures (NGGSs) for decreasing postoperative complications. This study aimed to assess and compare the safety and effectiveness of MIDBAND with or without gastro-gastric sutures (GGSs). METHODS Between February 2013...

PURPOSE Adjustable suture techniques are used to reduce the reoperation rate in strabismus surgery, but traditionally require that final adjustments be made between 1 to 24 hours after surgery. The purpose of this study was to evaluate a new anesthetic technique that would allow immediate postoperative adjustment of sutures in strabismus surgery, thereby improving patient convenience and comfor...

BACKGROUND Underlying left ventricular (LV) dysfunction contributes to poor survival after operation to correct ischemic mitral regurgitation (IMR). Many surgeons do not appreciate that a key component of the Bolling undersized mitral ring annuloplasty concept is to decrease LV wall stress by altering LV shape, but precise 3-dimensional (3-D) geometric data do not exist substantiating this effe...

PURPOSE To demonstrate the feasibility of a miniature handheld optical coherence tomography (OCT) imager for real time intraoperative vascular patency evaluation in the setting of super-microsurgical vessel anastomosis. METHODS A novel handheld imager Fourier domain Doppler optical coherence tomography based on a 1.3-µm central wavelength swept source for extravascular imaging was developed. ...

Functional tricuspid regurgitation (FTR) is a neglected and underestimated pathology. It occurs mostly from annular dilatation and right ventricular enlargement, which is frequent secondary to left-sided heart failure from myocardial or valvular causes, right ventricular volume and pressure overload, and dilatation of the cardiac chambers. Moderate-to-severe FTR should be corrected to improve s...
