Abstract Background Lumboperitoneal (LP) shunts have been described as a safe and effective option for idiopathic intracranial hypertension (IIH). However, it had many complications, including migration. Herein, we report our experience regarding the incidence, different sites, presentation, management of LP shunt migration in patients with IIH. Patients methods This retrospective series review...

Abstract In this paper, we design a tunable phase-modulated metasurface composed of periodically distributed piezoelectric patches with resonant-type shunt circuits. The electroelastic can control the wavefront lowest antisymmetric mode Lamb wave ( A 0 mode) in small footprint due to its subwavelength features. fully coupled electromechanical model is established study transmission characterist...

OBJECTIVE Recently, heparin coated polytetrafluoroethylene (PTFE) shunts are available and are believed to improve inherent shunt problems such as thrombosis and excessive and incomplete neointima formation or occlusion. We aimed at comparing the potential histopathological differences in the neointima (in) between uncoated (UCS) PTFE shunts and heparin coated (HCS) PTFE shunts. MATERIALS AND...

BACKGROUND Although the use of temporary shunts in proximal extremity amputations has been reported, no study has described the use of temporary shunts in distal extremity amputations that require vein grafting. Moreover, the total volume of blood loss when temporary shunts are used has not been reported. The aim of this study was to investigate the applicability of a temporary shunt for distal...

There is dispute as to whether paradoxical gas embolism is an important aetiological factor in neurological decompression illness, particularly when the spinal cord is affected. We performed a blind case-controlled study to determine the relationship between manifestations of neurological decompression illness and causes in 100 consecutive divers with neurological decompression illness and 123 ...

PURPOSE To evaluate three different percutaneous portosystemic shunts created with magnetic resonance (MR) imaging and fluoroscopy guidance in a swine model. MATERIALS AND METHODS In stage 1 of the experiment, an active MR intravascular needle system was created for needle tracking and extracaval punctures. Twenty inferior vena cava (IVC)/superior mesenteric vein (SMV)/portal vein (PV) punctu...

Arteriovenous malformations (AVMs) are tortuous vessels characterized by arteriovenous (AV) shunts, which displace capillaries and shunt blood directly from artery to vein. Notch signaling regulates embryonic AV specification by promoting arterial, as opposed to venous, endothelial cell (EC) fate. To understand the essential role of endothelial Notch signaling in postnatal AV organization, we u...
