The pathogenesis of the cauda equina syndrome of ankylosing spondylitis is unknown. The long duration between the onset of ankylosing spondylitis and neurological symptoms (average 35 years in the Mayo Clinic series') argues against a shared inflammatory cause, as does the relative normality of CSF.' 2 Matthews suggested that arterial pulsations transmitted to the CSF might produce not only the...

the aim of this study is to evaluate early and late results of surgery in children with congenital heart disease and decreased pulmonary blood flow, who underwent a palliative systemic-to-pulmonary shunt. during the past 9 years, 157 systemic-to-pulmonary artery shunts were performed in 130 patients (69 males, 61 females) with ages from 1 day to 31 years old. they had been evaluated for their c...

this is a case of a modified blalock-taussig shunt, which was complicated by perigraft transudative, fibrinous fluid accumulation and recurrence after surgical intervention. follow-up and expectant management of the patient was successful. our experience regarding this complication is presented.

Hepatoportal sclerosis or idiopathic portal hypertension has a worldwide distribution with prevalence in developing and temperate countries. Of 64 patients with this disease seen during a twelve year period, 36 underwent splenectomy or a shunt procedure. The indications for surgical intervention were severe hypersplenism and persistent left upper abdominal pain andlorhistory of frequent ep...

conclusions we found that ei and qp/qs ratio are significantly and positively associated and qp/qs ratio can be easily estimated by measuring ei in secundum type asd patients. background one of the inclusion criteria for applying atrial septal defect (asd) closing procedure is an increased pulmonary-to-systemic blood flow ratio (qp/qs). eccentricity index (ei) is associated with ventricular dys...

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...

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...
