Dilation of blood vessels transluminally was demonstrated by Dr Andreas Gruntzig in 1978. In 1982, Kan demonstrated that congenitally stenosed valve can be dilated with the use of cylindrical balloon and opened up new vistas in the non-surgical treatment of congenital heart lesions. Rapid progress has been now made in (1) Understanding of mechanism of success or failure of balloon dilation (2) ...
Balloon dilation of the Eustachian tube has been recently introduced as a novel and minimally invasive method for treating chronic obstructive Eustachian tube dysfunction. For the first time worldwide, we assessed the role of this technique in the treatment of children with Eustachian tube dysfunction who did not respond to other treatments. We retrospectively analysed the medical records of 60...
The use of catheters to dilate vascular obstructions began as early as 1964. In their classic article, Dotter and Judkins (1) described transluminal dilation of arteriosclerotic obstruction. It wasn’t until 10 years later that the use of balloontipped catheters in coronary artery dilations was reported by Gruentzig and Hopff (2) and later applied by Gruentzig and his colleagues (3). Since these...
OBJECTIVES To describe our management of complex glottic stenosis in tracheotomy dependent children with severe recurrent respiratory papillomatosis. METHODS Retrospective chart review at a tertiary care children's hospital. RESULTS Three children with complex glottic stenosis secondary to severe recurrent respiratory papillomatosis were treated at our institution since 2011. Two patients h...
OBJECTIVES To analyze immediate and long-term results of balloon dilation for aortic coarctation in a three-center experience in Mexico, and to determine factors associated with increased risk. BACKGROUND Results demonstrated that the procedure is effective and safe, however its use in some groups is still controversial, specially in neonates and infants. METHODS In a ten-year period, 333 p...
We present a rare case of functional stenosis of the jejunal loop following left hepatectomy and hepaticojejunostomy long after pylorus-preserving pancreaticoduodenectomy (PPPD), which was successfully managed by balloon dilation. A 70-year-old Korean man had undergone PPPD 6 years before due to 1.8 cm-sized distal bile duct cancer. Sudden onset of obstructive jaundice led to diagnosis of recur...
BACKGROUND Controversy still exists over the optimal balloon size, extent of vascular disruption, and long-term results of balloon dilation therapy for coarctation of the aorta. Intravascular ultrasound imaging has been used in patients with coronary artery disease to provide further insight into the anatomy of atherosclerotic lesions and the results of angioplasty and atherectomy. Initial obse...
BACKGROUND The objective of this prospective, multicenter study was to assess 1-year changes in sinonasal symptoms and health care use after office-based multisinus balloon dilation. METHODS Adults diagnosed with chronic or recurrent acute rhinosinusitis per the 2007 adult sinusitis guidelines were enrolled in this Institutional Review Board-approved study. Balloon dilation of the maxillary s...
Endoscopic therapy is the first line treatment for patients with common bile duct (CBD) stones. Removing bile duct stones by ERCP requires enlarging the papillary opening, either by cutting the biliary sphincter with an endoscopic sphincterotomy or by endoscopic papillary balloon dilation. Dilation has the advantage of sphincter preservation and a lower risk of hemorrhage but carries an increas...
