PURPOSE: Glaucoma is a frequent and often severe problem in patients needing keratoprosthesis (KPro) surgery. Standard glaucoma shunts in these cases often develop a very dense capsule that obstructs flow and causes intraocular pressure elevation. Therefore, we developed shunts that deliver aqueous to distant epithelialized cavities where an obstructing capsule ...

BACKGROUND: To evaluate the feasibility of echocardiography after transcatheter closure of patent ductus arteriosus (PDA) with coils. METHODS: Between April 1998 and December 2006, 131 patients had transcatheter coil occlusion of their PDA using Gianturco coils. We hypothesized that post-procedural hemolysis would not occur if a residual shunt < 1 ...

OBJECT: In Uganda, childhood hydrocephalus is common and difficult to treat. In some children, endoscopic third ventriculostomy (ETV) can be successful and avoid dependence on a shunt. This can be especially beneficial in Uganda, because of the high risk of infection and long-term failure associated with shunting. Therefore, the authors ...

BACKGROUND: Temporary intravascular shunts (TIVS) are now widely used in vessels injuries. Little information concerned how long TIVS can safely maintain patency for in the setting of damage control surgery (DCS). We compared four different shunt-indwelling times in previous established superior mesenteric artery (SMA) injury models and aimed to find ...

Overdrainage is a common complication observed after shunting patients with idiopathic normal-pressure hydrocephalus (iNPH), with an estimated incidence up to 25%. Gravitational units that counterbalance intracranial pressure changes were developed to overcome this problem. We will set out to investigate whether the combination of a programmable valve and a gravitational ...
