balloon dilatation of stricture is one of the new treatment methods among patients with gastric outlet obstruction (goo). however, the prevalence and underlying etiologies of goo in various populations are different. the goal of the present study was to determine the effectiveness of endoscopic balloon dilatation and factors that would affect its success rate patients with benign etiology for g...

Background: The aim of this study is to evaluate whether the location of the balloon placement into either the cervical canal or uterine cavity during sonohysterography can affect the intensity of pain. Materials and Methods: A total of 300 infertile women undergoing sonohysterography were randomized to intracervical or intrauterine balloon placement. The examination was scheduled in the early ...

Szöcs and colleagues, 1 in this issue of Arteriosclerosis, Thrombosis and Vascular Biology, have added to our understanding of the role of NAD(P)H oxidase and reactive oxygen species in vascular injury. The study was undertaken by using the rat carotid artery balloon injury model, a well-characterized model of neointimal formation. In this model, vascular balloon injury leads to medial smooth m...

statement of problem comprehensive diagnosis is regarded as an important base for orthodontic treatment. an effective way to reach a correct diagnosis is to compare the craniofacial skeleton of patients with normal cases in the same race through lateral cephalograms. purpose the present study was designed to determine the cephalometric standards of senior high school students in the city of ham...

background although heller myotomy is one of the most effective treatments for achalasia, it may be associated with early or late symptom relapse in some patients. therefore, additional treatment is required to achieve better control of symptoms. aim : to evaluate the safety and efficacy of pneumatic balloon dilation (pbd) in patients with symptom relapse after heller myotomy. methods thirty si...

Endovascular stents expand the arterial lumen more than balloon angioplasty and reduce rates of restenosis after coronary angioplasty in selected patients. Understanding the factors involved in vascular injury imposed during stent deployment may allow optimization of stent design and stent-placement protocols so as to limit vascular injury and perhaps reduce restenosis. Addressing the hypothesi...

OBJECTIVES This study was undertaken to investigate the incidence of posttransplant recoarctation of the aorta, delineate the mode of presentation, identify risk factors that predict recoarctation and examine the results of intervention for posttransplant recoarctation. BACKGROUND Patients with aortic arch hypoplasia require extended arch reconstruction at transplant, with an inherent possibi...

Congenital esophageal atresia needs to be surgically corrected as soon as possible. Some will present with post surgical stricture that needs to be dilated by a balloon dilator. This procedure is difficult in premature born due to infant esophageal size and availability of equipments. We herby report the first case in a premature infant with post surgical esophageal stricture of esophageal atre...

Two different types of latex calibrated-leak balloon catheters have been developed. One consists of a Teflon catheter with a detachable latex balloon and is used to embolize branches of the external carotid artery. The other consists of a Silastic catheter with a nondetachable latex balloon and is used to embolize brain arteriovenous malformations. An experimental model and animal experiments h...
