Aortic Rupture by an Acute Dissection of the Thoracoabdominal Aorta in a 12-Year-Old Boy.

Aortic dissection is exceptional in children. When they are affected, many clinical conditions as Marfan syndrome or Ehlers-Danlos syndrome are usually involved, but up to 22% have no associated background. Its high morbidity and low incidence in this age group require a high level of suspicion in children without predisposing factors when the presentation is atypical, to avoid the severe consequences of the delay of their diagnosis.

Preoperative Squid embolization of carotid paragangliomas with direct puncture.

Background And Purpose: Preoperative embolization of carotid paragangliomas is a common procedure in interventional neuroradiology. Direct puncture embolization has shown less morbidity and mortality than endovascular embolization and a higher percentage of devascularization. We describe our experience using Squid® as the only embolic agent in direct puncture glomus embolization.

Thoracic Stent Grafting through Transapical Approach for Type III Endoleak due to Prosthetic Disconnection.

Thoracic endovascular aortic repair is a well-established treatment of descending thoracic aneurysms, and increasingly complex endovascular procedures including aortic arch and ascending aorta are being performed. However, follow-up complications may be expected, which will enhance the need for alternative approaches such as transapical, in case of complex anatomies and reinterventions. We report the case of a man with prior history of ischemic cardiopathy and multiple endovascular aortic interventions with proximal landing in zone 1 and distal landing proximal to celiac trunk.

Prospective study of safety and effectiveness in the use of radiofrequency ablation for incompetent great saphenous vein ≥12 mm.

Development of a Telemetric System for Postoperative Follow-up of Vascular Surgery Procedures: In Vitro Model.

Background: Because of the unique electromagnetic characteristics of the magnetoelastic microwire, the changes in the pressure of a fluid will provoke a variation of the mechanical pressure on the sensor, which will cause a variation of its magnetization that will be detectable wirelessly. Thus, a wireless system can be developed for following up vascular surgery procedures.

Methods And Results: The sensor consists of a magnetoelastic microwire ring, which was integrated into an in vitro model with pulsatile flow.

Systematic nasogastric tube in aortic surgery: is it necessary?

Background: Routine nasogastric tube (NGT) decompression has been traditionally used to prevent nausea and vomiting after abdominal surgery. Besides, many studies having demonstrated no benefits derived from this practice after an elective laparotomy, little evidence has been published regarding its use in aortic surgery. In this study, we analyze the effects of the selective use of the NGT in patients undergoing infrarenal aortic surgery in our center.

Comparison of popliteal artery aneurysm therapies.

Objective: Surgical treatment of popliteal artery aneurysms (PAAs) has advanced over time.
