THE JOURNAL OF CARDIOVASCULAR SURGERY 1 enable the patient to enter into a relaxed state in preparation for sleep. Within this state, the brain naturally progresses through alpha and delta brainwave stages leading to the most conducive condition of mind and body for deep, natural sleep.11-14 The goal of this preliminary investigation was to lay the groundwork to test the applicability of using ...

OBJECTIVE To describe a successful pregnancy after a change in configuration of the endometrial cavity after magnetic resonance imaging-guided focused ultrasound surgery (MRgFUS) for leiomyomas. DESIGN Case report. SETTING University hospital. PATIENT A 40-year-old woman with known leiomyomas and a history of secondary infertility. INTERVENTION Magnetic resonance imaging-guided focused ...

Anesthetic management of patients with preexisting diseases is challenging and individualized approaches need to be determined based on patients' complications. We report here a case of ultrasound-guided epidural anesthesia in combination with low-dose ketamine during cesarean delivery on a parturient with severe malformations of the skeletal system and airway problems. The ultrasound-guided ep...

BACKGROUND Endoscopic ultrasound (EUS) guided fine-needle aspiration (FNA) of pancreatic lesions is being increasingly used. Our aim was to determine the safety, accuracy, and clinical utility of EUS-guided FNA in both the diagnosis and staging of pancreatic cancer. METHODS Forty-four patients (24 men/20 women) had EUS-guided FNA of pancreatic lesions (39 head/neck, 5 body, 3 tail) and/or ass...

The incorporation of virtual engineering into dentistry and the digitization of information are providing new perspectives and innovative alternatives for dental treatment modalities. The use of digital surface scanners with surgical planning software allows for the combination of the radiographic, prosthetic, surgical, and laboratory fields under a common virtual scenario, permitting complete ...

BACKGROUND Wide-awake hand surgery is useful for tendon reconstruction because surgeons can observe the actual movement of the reconstructed tendons during the surgery. We hypothesized that accurate ultrasound-guided injection of local anesthetics into the sensory nerves contributes to reliable analgesia with a relatively small amount of anesthetic. METHODS We enrolled 8 patients who underwen...

The application of computed tomography (CT) and the use of computer software for dental implant therapy have significantly increased during the last several years. Dental implant positioning can be either "partially guided," where only osteotomy sites are prepared using sequential, removable surgical drilling guides (generated using computer software and through the process of stereolithography...

One of the key requirement in image guided surgery (IGS)/ computer aided surgery (CAS) planning is accurate segmentation of the images concerned. It is also a challenging issue for the purpose of image analysis and understanding in general, and surgical intervention involving image guided surgery (IGS) in particular. Thus, in this paper, a technique employing two-stage segmentation in which one...
