BACKGROUND Ventricular shunts are used to drain cerebrospinal fluid into extra-cranial spaces. Ventriculoatrial (VA) shunts are provided to transfer cerebrospinal fluid from the cerebral ventricle into the right atrium of the heart. A single center experience of indications, procedure, and clinical outcomes in VA shunt was presented in current study. METHODS VA shunts were applied in 10 patie...

BACKGROUND The occurrence of a snare-related stenosis after beating-heart surgery prompted the search for an alternative method of hemostasis. Because of the shortcomings of commercial coronary shunts a novel custom-made coronary shunting technique was devised. It involves the use of varying lengths of 1.2-mm Silastic tubing secured with a fine silk "tag" suture. The technique of construction a...

Typically, inserted-shunt integrated transformers have symmetric primary and secondary leakage inductances. However, bidirectional resonant converters typically operate more efficiently with different series In this paper, a new topology for an transformer which can provide tunable, asymmetric (series) inductances on the sides is presented. Two magnetic shunts, appropriate air gaps, are inserte...

Background and Importance: Lumboperitoneal shunts are commonly used to treat several conditions, but their use can result in significant complications. We discuss a complication of these shunts that has not been reported in the literature to date. Case Presentation: An obese, 41-year-old woman admitted to Rasool Akram Hospital complaining of a severe headache and blurred vision. The ...

The application of transcranial Doppler ultrasound to the diagnosis of blocked ventriculo-peritoneal shunts was studied in 63 children. Thirty two of these required shunt revision, whereas in 31 children symptoms resolved without surgery. The group of children requiring shunt revision had a significantly higher mean Gosling pulsatility index, than both the group of children whose symptoms resol...
