INTRODUCTION Breast radial scar (RS) management remains controversial. The need for surgical excision is supported by the concern of an associated high-grade lesion missed in the biopsy. The aim of this study was to assess histologic upgrade rate after a percutaneous biopsy, to determine if vacuum assisted biopsy prevents the need for subsequent RS surgical(More)
OBJECTIVE To investigate the ability of 16-slice multidetector computed tomography (MDCT) to assess coronary artery bypass graft patency and to detect bypass stenosis by comparison with coronary angiography. METHODS Thirty patients underwent both conventional coronary bypass angiography and retrospective ECG gated 16-slice multidetector computed(More)
AIMS Uncertainty persists regarding the impact of the off-pump technique on coronary bypass graft patency. The primary objective of this study was to assess coronary artery bypass graft patency in patients randomized to off-pump and on-pump multivessel coronary artery bypass grafting (CABG). Secondary objectives were clinical outcomes and neuropsychological(More)
OBJECTIVE Obesity is considered a risk factor for the occurrence of complications after cardiac surgery. The objective of this study was to analyze mortality and morbidity in patients with morbid obesity following heart surgery. DESIGN Retrospective study in a tertiary care setting. METHODS Out of 1815 adult patients undergoing cardiac surgery, 50(More)
OBJECTIVE Gender is a well-known risk factor for mortality and morbidity after coronary artery bypass grafting and various reasons have been proposed to explain the poorer results observed in women. The study objective was to determine whether female gender was still an operative risk factor with the adoption of off-pump coronary artery bypass surgery. (More)
OBJECTIVE To compare 4 methods of myocardial protection in GABG in terms of markers of myocardial ischemia, mortality, morbidity and mid-term results. MATERIAL & METHODS Retrospective study of 241 consecutive patients undergoing isolated > 1 CABG using one of 4 methods: off-pump (OFF, n = 108), cardiopulmonary bypass (CPB) and cardioplegia (CARD, n = 66),(More)
Four patients with unstable angina due to left main or three-vessel disease scheduled for coronary artery bypass grafting were found intra-operatively to have porcelain ascending aorta, defined as massive calcification of the ascending aorta from the aortic valve to the transverse arch, precluding ascending aorta cannulation or clamping. A no-touch(More)
OBJECTIVE To analyze the early results of coronary surgery without cardiopulmonary bypass using the EuroSCORE risk model. METHODS Out of a series of 1104 consecutive patients undergoing CABG during a 20-month period and whose data were prospectively collected, 1083 patients (98.1%) were operated without cardiopulmonary bypass (CPB) and represent the(More)
METHODS We performed Echo color Doppler examinations on 100 glaucomatous patients (197 eyes). Ophthalmic artery and central retinal artery were particularly considered. The study included eyes in every level and type of glaucoma, and in various types of treatment (topical therapy, Argon laser trabeculoplasty, Argon/YAG/surgical iridectomy, trabeculectomy).(More)
