BACKGROUND Thoracic stent-grafts (TSG) show excellent early and mid-term results for localized diseases of the descending aorta. Extending TSG applications for arch pathologies or to other yet unproven indications remains to be established. We herein report our experience in 18 patients with extended applications of TSG. METHODS Ten patients with(More)
PURPOSE To report a pitfall encountered during stenting of a complicated penetrating ulcer of the descending thoracic aorta. CASE REPORT A 65-year-old man was diagnosed with a complicated penetrating ulcer of the thoracic aorta. A 38-mm Talent endograft was implanted. On balloon dilation of the distal end of the endoprosthesis, the terminal bare stent(More)
OBJECTIVE : Use of thoracic Stent-graft in patients with connective tissue disorders (CTD) remains limited. We herein report 3 patients with CTD who underwent stent grafting. METHODS AND RESULTS : Case 1; A male Marfan patient was operated for thoraco-abdominal aneurysm. On computed tomography (CT), large false aneurysm at the proximal anastomosis was(More)
PURPOSE To report a new access technique for endovascular treatment of penetrating ulcer of the proximal descending aorta. TECHNIQUE When traditional access routes are unavailable, a 10-mm Dacron graft can be sutured to the distal descending aorta using a video-assisted mini-thoracotomy. Prerequisites for use of this novel approach are a focal lesion of(More)
In this paper, two architectures for high-speed time-resolved imaging circuits in (Bi)CMOS technology are presented. The first architecture adopts the traditional for the most silicon imagers matrix configuration, where the photocharges-induced signal is processed directly in-pixel. The second approach is based on a single light detecting vector, comparable(More)
This paper presents the state of the art of the Integrated Streak Camera (ISC) architectures in standard CMOS technology. It focuses on some of the methods required for reconstructing the luminous events profile from the chip raw data. Two main ISC architectures are presented. The first adopts the traditional for the most silicon imagers pixel array(More)
A Macropixel for photon counting integrated streak camera has been developed in a 180nm standard CMOS process. It includes a 4×4 array of Single Photon Avalanche Diodes (SPAD) acting as a small and smart SiPM (Silicon Photo Multiplier), a unique quenching circuit and a 16 bits memory for smart pixel operation. The total Macropixel size is(More)
