pulmonary arterial hypertension (pha) is a frequent complication of congenital heart disease (chd), most commonly in systemic-to-pulmonary shunt lesions. in patients with an uncorrected left-to right shunt, pah will end up to eisenmenger’s syndrome, which is contraindication of surgery. what about patients with moderate to severe pah, who do not have criteria of eisenmenger’s syndrome; immediat...
Schizencephaly is a rare congenital brain malformation characterized by clefts in the cerebral cortex, it classified Type I (open lip) and II (close-lip). Patients with schizencephaly present seizures, hydrocephalus, motor mental deficits. Ultrasound used for in-utero newborns patients’ diagnosis, MRI or CT already born patients. The management of conservative, rehabilitation deficits, medicati...
A dialysis patient with hyperammonaemia: inferior mesenteric-caval shunt as a cause of portal-systemic encephalopathy Sir, We report here a rare case of portal-systemic encephalop-athy with occasional loss of consciousness caused by an inferior mesenteric-caval shunt via the internal iliac vein in a peritoneal dialysis (PD) patient who was switched to haemodialysis (HD). A 71-year-old man with ...
weeks. A neurosurgical consultant refused to accept Case report our recommendation of shunt removal as he was not convinced of the diagnosis. A week after the initiation In August 1995, an 18-year-old youth was initially of antibiotic therapy, 3 and 4 levels increased to 205 referred for the evaluation of microscopic haematuria and 11 mg/dl, respectively. However, a fortnight foldiscovered on a...
OBJECTIVE To determine portal hemodynamic changes associated with surgical shunt ligation and establish ultrasonographic criteria for determining the optimal degree of shunt narrowing and predicting outcome. DESIGN Case series. ANIMALS 17 dogs, each with a single congenital extrahepatic portosystemic shunt. PROCEDURE Pre- and postligation flow velocities and flow directions were determine...

choice. However, the data regarding the surgical management of NCC is quite insufficient, especially for extraparenchymal NCC. Many scholars advocate that anti-parasitic therapy should be considered as a priority in parenchymal NCC and steroids and anti-epileptic drugs are also chosen commonly in case of brain edema and seizures caused by the cysticerci (2,5,10). In contrast, extraparenchymal N...
OBJECTIVE To determine the usefulness of a separate reservoir placed at the site of the shunt in evaluation of shunt malfunction. METHODS AND MATERIALS A ventricular catheter was placed alongside the proximal catheter of the shunt and connected to a subgaleal reservoir in 17 patients, in 9 a double-lumen catheter with integrated reservoir and in 13 patients a dual catheter with a double-port ...
Since the isotopes can not be utilized for veterinary patients in Japan, the authors developed a simple calculation formula of shunt fraction of portosystemic shunt based on the hepatic circulation model. The shunt fraction can be calculated utilizing only 2 portal pressure measurements of pre-shunt ligation and temporary or permanent shunt ligation. The calculated shunt fraction can obtained p...
