Implantation Strategy of the Atrial Dipole Impacts Atrial Sensing Performance of Single Lead VDD Pacemakers

2002

WIEGAND, U.K.H., et al.: Implantation Strategy of the Atrial Dipole Impacts Atrial Sensing Perfor-mance of Single Lead VDD Pacemakers. Intermittent atrial undersensing is observed in a considerable percentage of patients with single lead VDD pacemakers. Analyzing the 2-year data of the Saphir Multicenter Follow-Up Study, the authors investigated predictors for the occurrence of undersensing. The study included 194 patients with high degree AV block who received a VDD pacemaker system with an identical sensing amplifier. Placement strategy of the atrial dipole was left to the discretion of the implanting physician. At the final position, atrial potential amplitudes were measured during deep …

Interventistica eco-guidata per l’articolazione d’anca

2013

Lo scopo di questo lavoro è di rivedere le principali applicazioni della interventistica eco-guidata d’anca, descrivendone le indicazioni e la metodologia. L’ecografia è una metodica considerata sicura per i pazienti, in quanto non è stato dimostrato un possibile danno dovuto all’energia trasmessa dagli ultrasuoni ai tessuti del paziente, contrariamente alle metodiche che fanno uso di radiazioni ionizzanti, come la radiografia convenzionale e la tomografia computerizzata. Inoltre, l’ecografia risulta rapida ed efficace nel guidare l’ago verso la sede voluta evitando di intercettare strutture vascolari e/o nervose, consentendo quindi una maggiore sicurezza, rispetto alle tecniche interventis…

The purpose of this work is to review the main applications of ultrasound-guided hip intervention al procedures describing the indications and methodology. Ultrasound is a method considered safe for patients as it has not been shown a possible damage due to ultrasound energy transmitted towards the patient's tissues as opposed to methods that make use of ionizing radiation such as conventional radiography and computed tomography. In addition ultrasound is quick and effective in guiding the needle to the desired location avoiding vascular and/or nerve structures thus enabling greater security compared to the techniques performed in interventional fluoroscopy which also have the disadvantage of a large delivery of ionizing radiation for both patient and operator. Several authors have described the main techniques of ultrasound-guided hip intervention and its various applications that can be both diagnostic (as in the case of joint fluid aspiration to assess the presence or absence of septic arthritis) and therapeutic (as in the case of drugs inoculations or evacuation of exceeding intra-articular fluid).

Fully robotic Ivor–Lewis esophagectomy (RAMIE4) for esophageal cancer after emergency surgery and ligation of the gastroduodenal artery

2018

We report a case of a 69-year-old patient with esophageal cancer and severe upper gastrointestinal bleeding during neoadjuvant radiochemotherapy who required mass transfusion followed by complex emergency procedures. Despite endoscopic stenting, the bleeding recurred, and thus emergency open surgery was required. Gastric wedge resection of the minor curvature necessitated by perforation caused by the endoscopic stent maneuver and duodenotomy with ligation of the gastroduodenal artery, as the cause of persistent intraluminal bleeding, were performed. The already prepared gastric conduit during the emergency operation did not become ischemic, even though the gastroduodenal artery, left gastr…

Differences in Accuracy and Radiation Dose in Placement of Iliosacral Screws: Comparison between 3D and 2D Fluoroscopy

2022

Percutaneous iliosacral screw fixation is a widely accepted method of stabilizing the posterior pelvic ring. Recently developed tools such as 3D-navigated fluoroscopy and computed navigation seem to prevent a surgeon from conducting screw misplacement. The study aimed to comparatively assess the introduction of sacroiliac screw placement using 2D and 3D fluoroscopy in terms of accuracy and radiation exposure. Iliosacral screws were introduced in 37 patients using 2D (group N1) and in 36 patients using 3D fluoroscopy (group N2) techniques. Overall, 61 and 56 screws were introduced in groups N1 and N2, respectively. Screw placement accuracy was assessed using postoperative computed tomography…
