Congenital or acquired branch pulmonary artery stenosis can produce significant right ventricular hypertension and complicate
the management of patients with tetralogy of Fallot. Repair is difficult using conventional surgical techniques. Balloon dilation
angioplasty may be beneficial to some patients with these lesions. The technique currently used at the University of Minnesota
is described. Results indicate that half of attempted dilations are successful with increased diameter of the narrowed areas,
decreased pressure gradient, and improved pulmonary blood flow to the involved lung. Failure may be caused by technical limitations
(28%) or lesions that are not dilatable with current equipment (22%). Undilatable lesions are more common in children over
2 years of age, in isolated pulmonary artery stenosis, and with associated surgical shunts. Complications are uncommon. 相似文献

Percutaneous transluminal angioplasty (PTA) of the vertebral artery was performed with an autoperfusion balloon catheter in five patients. There were no complications in the form of embolic episodes or neurological deficits due to brain ischaemia during inflation. In critical cases with insufficient collateral circulation during temporary occlusion, the use of an autoperfusion balloon catheter may expand the indications for PTA in patients with ischaemic cerebrovascular disease. 相似文献

Purpose:
To evaluate the results of percutaneous balloon dilation of benign bile duct strictures in a series of patients with a long follow-up period. Material and Methods:
56 patients with benign bile duct strictures underwent balloon catheter dilation. These patients had strictures of various origins: postsurgical, postlocal not surgical treatments, associated with gallstones, due to primary sclerosing cholangitis and to Mirizzi's syndrome. In 41 cases the diagnosis was made on the basis of radiological findings and history and in 15 cases on the basis of transluminal biopsy. Results:
In 87.5% of cases the treatment was immediately successful. There were no early recurrences, but 7 (21%) recurrences were seen over 1 year after treatment; of these, 57% underwent another balloon dilation procedure with a positive long-term outcome. Conclusion:
The long-term success rate obtained in 72% of this series confirms that percutaneous bile duct dilation is a valid alternative to surgery without being burdened by complications; the procedure is also a valid alternative to the approach using endoscopic stents. 相似文献

Treatment of esophageal stenosis by large diameter balloon catheters offers significant advantages over bouginage. Catheter
dilating force is confined to the affected segment and can be controlled by the patient's reaction. Perforation is practically
excluded by the use of fluoroscopy, contrast media, flexible angiographic guidewires, and better control over the time and
forces of dilation. Wider, more lasting dilation can be achieved. Forty-one dilations were done on 21 patients with this new
procedure without complications and with improved relapse-free intervals. 相似文献

Gastric balloons have been used extensively as an adjunct to diet and behavioral modification in the treatment of exogenous
obesity. Small bowel obstruction occurred in a 42-year-old female after her balloon migrated through the pyloric channel.
The authors describe a simple method for percutaneous deflation which permitted the balloon to pass through the gastrointestinal
tract thus relieving the obstruction. 相似文献
