The relation between the size of the balloon used for dilatation of the pulmonary valve and the extent of relief of pulmonary stenosis both immediately after and at intermediate term follow up was studied. Sixty four balloon dilatation procedures in 56 patients were divided into group 1-12 in which the ratio of the diameter of the balloon to that of the pulmonary annulus was less than or equal ...

OBJECTIVE We wanted to evaluate the therapeutic efficacy of the percutaneous balloon dilatation and large profile catheter maintenance method for the management of patients with anastomotic biliary strictures following liver transplant. MATERIALS AND METHODS From May 1999 to June 2003, 12 patients with symptomatic benign biliary stricture complicated by liver transplantation were treated with...

This study evaluated the mechanism of valvular area expansion during singleand doubleballoon valvuloplasty in fibrotic and calcific mitral valves. Special interest was focused on the morphological features of the valves treated. Mitral valves that appeared unsuitable for commissurotomy were excised in toto at the time of mitral valve replacement in 15 patients. The excised valves were mounted i...

Balloon dilatation in infants with severe pulmonary valve stenosis may not be a straightforward procedure once the arterial duct has closed. Balloon dilatation was attempted in three neonates and infants. In an 11 week old infant hypotension and bradycardia developed shortly after a 5 French end hole catheter was passed through the severely stenosed pulmonary valve. An emergency Waterston shunt...

In colonoscopic study, benign colorectal strictures with or without symptomatic pain are not rarely encountered. Benign colorectal stricture can be caused by a number of problems, such as anastomotic stricture after surgery, inflammatory bowel disease, postendoscopic submucosal dissection, diverticular disease, ischemic colitis, and so on. There are various modalities for the management of beni...

Percutaneous balloon dilatation of a Waterston anastomosis was performed in a child who had had four shunt operations. Initially, the procedure was apparently successful, but pulmonary oedema developed and he died 12 hours after the procedure. Balloon dilatation of a Waterston anastomosis is technically possible and may prove to be an alternative to reoperation in certain patients. But further ...

A two week old girl with tetralogy of Fallot and atrioventricular septal defect underwent palliation, for severe hypoxaemia, by balloon dilatation to the right ventricular outflow tract. This procedure was repeated once over the next eight months without complications. Serial right ventricular angiograms showed growth of the hypoplastic pulmonary ring ("annulus"), trunk, and arteries. Balloon d...

Pott's Puffy tumor (PPT) is a rare entity characterized by subperiosteal abscess associated with osteomyelitis of the frontal bone. It is usually managed by surgical curettage of the osteomyelitic bone and long-term antibiotic therapy. Balloon catheter dilatation is a new technique which was recently introduced for the treatment of chronic rhinosinusitis. In this article, we present three PPT c...

A three year old girl with severe congenital mitral stenosis was successfully treated by percutaneous balloon dilatation of the mitral valve. Cardiac catheterisation and cross sectional and Doppler echocardiography indicated that the orifice of the mitral valve had doubled in area. A small atrial septal defect was found at follow up cardiac catheterisation and angiography. Balloon dilatation of...

OBJECTIVE To investigate the evidence for balloon dilatation of the eustachian tube using a transtympanic approach. METHODS A systematic search of several databases was conducted (using the search terms 'dilation' or 'dilatation', and 'balloon' and 'eustachian tube'). Only studies that used a transtympanic approach for the procedure were included. These studies were then assessed for risk of ...
