Current role of the chimney technique in the treatment of complex abdominal aortic pathologies: A position paper from the PERICLES Registry investiga…

2020

Historically, chimney/snorkel endovascular aortic repair (Ch-EVAR) emerged as a rescue technique to revascularize and/or preserve inadvertently covered critical branch vessels during infrarenal aortic endografting. Next, in its evolutionary path, Ch-EVAR offered a viable treatment option for complex aortic repair, and particularly in situations where fenestrated/ branched EVAR was not a therapeutic option due to the lack of availability and/or anatomical constraints. In this context, this technique offered distinct advantages such as off-the-shelf availability, straightforward implantation techniques, and lower resource use-intensity enabling performance by a large number of operators manag…

Endoscopic Neurosurgery “Around the Corner” with a Rigid Endoscope. Technical Note

1999

Endoscopically "working around the corner" is presently restricted to the use of flexible endoscopes or an endoscope-assisted microneurosurgical (EAM) technique. In order to overcome the limitations of these solutions, endoscopic equipment and techniques were developed for "working around the corner" with rigid endoscopes. A steering insert with a 5 French working channel is capable of steering instruments around the corner by actively bending the guiding track and consecutively the instrument. A special fixation device enables strict axial rotation of the endoscope in the operating field. Endoscopic procedures "around the corner", including aqueductal stenting, pellucidotomy, third ventric…

Recurrent gastrointestinal haemorrhage from the distal duodenum

2006

In October 2004, a 69 year female patient presented with melena and anaemia (haemoglobin level 9 g/dl). The patient had been on warfarin due to construction of an aorto-bifemoral graft because of an aortic aneurysm and an …

Prosthetic strap system for simplified ventral hernia repair. Its results in a porcine experimental model.

2010

Abstract: Introduction Aiming to achieve a simplified ventral hernia repair, a proprietary shaped mesh was experimentally tested in the porcine model. The mesh is structured with a large central body and radiating straps. The friction of the straps passing through the tissues are hypothesized to be adequate to maintain the mesh in place during tissue ingrowth, avoiding classic point fixation while ensuring a wide coverage of the abdomen. Methods The mesh, having 6 radial straps, was placed using a sublay preperitoneal technique in 4 pigs. All straps were passed laterally through the abdominal wall and exteriorized from the skin. The straps were trimmed at the level of the skin, allowing the…

Fístula aortoentérica secundaria a infección de prótesis aortobifemoral

2002

Presentamos el caso de un hombre de 76 años, intervenido de una obstrucción iliaca bilateral mediante colocación de una prótesis aortobifemoral, que cinco años después presentó dolor en la fosa iliaca izquierda y fiebre en agujas de 39º C. En la exploración física destacaba un abdomen doloroso en la fosa iliaca izquierda con signos de irritación peritoneal. En las pruebas de laboratorio se detectó una leucocitosis con neutrofilia y hemocultivos negativos. La tomografía computadorizada (TC) objetivó la presencia de burbujas de gas alrededor de la prótesis, así como una colección líquida con áreas necróticas en su interior que afectaba a los músculos psoas e iliaco. En la misma exploración, l…

Hemosuccus pancreaticus--a rare cause of gastrointestinal bleeding: diagnosis and interventional radiological therapy.

2000

Hemorrhage from the pancreatic duct, i.e. hemosuccus pancreaticus (HP), is a rare cause of gastrointestinal bleeding. Pancreatic hemosuccus is usually due to the rupture of an aneurysm of a visceral artery, most likely the splenic artery, in chronic pancreatitis. Other causes of HP are rare. We present a case of HP in a female patient with no history but with positive findings of chronic calcifying pancreatitis upon ultrasonographic investigation, computed tomography scan, and endoscopic retrograde cholangiopancreatography. With detectable fresh blood in the descending duodenum, angiography of the celiac artery revealed an aneurysm of the splenic artery as the suspected cause of intermitten…

Multidisciplinary Approach for a Relapsing Goiter with Severe Tracheal Stenosis: A Case Report in an Elderly Patient

2012

Summary Total thyroidectomy is considered the gold standard for thyroid benign pathology treatment. Unfortunately, many partial interventions carried out in the past created many complications due to the tendency of the goiter to relapse and the formation of adherences in the anterior region of the neck. A woman 72 years of age with a relapsing goiter and severe respiratory symptomatology underwent thyroidectomy. After thyroid removal, tracheal stenosis persisted, making the positioning of a T silicon prosthesis (Montgomery’s T-tube) necessary. After 60 days, the prosthesis was replaced with a new made out of the same material but with a larger diameter and a softer consistency, which was r…

Nickel release after implantation of the Amplatzer occluder.

2003

Background Transcatheter closure of atrial septal defects is a new and less traumatic technique than open heart surgery. In recent years, patients with a patent foramen ovale sustaining potential paradoxical embolism have also become candidates for interventional closure devices. One of the more popular occluding devices is the Amplatzer septal occluder, which, like many other occluders, is made of nitinol. Nitinol-based alloys are widely used in medical products, for example, in orthopedics and orthodontics. However, the clinical use of nitinol, which contains 55% nickel, is still controversial because of concerns about its biocompatibility. Therefore, we examined the systemic nickel relea…

Acute inflammatory response after inguinal and incisional hernia repair with implantation of polypropylene mesh of different size.

2005

The purpose of this study was to assess the modifications of interleukin (IL)-6, C-reactive protein (CRP), leukocytes and fibrinogen after implantation of polypropylene mesh.Thirty-six patients were included in this study and divided into two groups. To the first group were allocated patients affected by inguinal hernia and undergoing conventional repair (subgroup Ia) or hernioplasty with 40-cm(2) polypropylene mesh (subgroup Ib). To the second group were allocated patients affected by incisional hernia and undergoing conventional repair (subgroup IIa) or incisional hernia repair with 400-cm(2) polypropylene mesh (subgroup IIb). Peripheral venous blood samples were collected 24 h before sur…
