Establishing tubal patency is necessary for the treatment of subfertility. Hysterosalpingo contrast sonography (HyCoSy) is one of recommended screening test but is expensive. Vaginal sonographic hydrotubation using agitated saline and size 8 Foley catheter can be used to reduce the cost. The objective of the study is to determine the diagnostic accuracy of vaginal sonographic hydrotubation usin...

We determined nasal peak flow using a peak flowmeter with a face mask (PALROD peak expiratory flowmeter) and nasal airway patency with an anterior rhinomanometer (Nihon Koden MPR-1100) at a minimum time interval in the same individual. We compared the values obtained by two kinds of measurements to evaluate the usefulness of the peak flowmeter for nasal airway patency. In this study, the nasal ...

Extended-release dipyridamole plus low-dose aspirin (ERDP/ASA) prolongs primary unassisted graft patency of newly created hemodialysis arteriovenous grafts, but the individual contributions of each component are unknown. Here, we analyzed whether use of aspirin at baseline associated with primary unassisted graft patency among participants in a randomized trial that compared ERDP/ASA and placeb...

This clinical study was performed to investigate the patency rate of endothelial cell-seeded small-diameter expanded polytetrafluoroethylene grafts during coronary artery bypass surgery. Between September 1995 and December 1998, 14 patients (median age: 71 years, range: 61-79 years) received 21 endothelial cell-seeded small-diameter grafts. In all, 43% of the performed implantations were reoper...

Abstract Background The concept of instrumentation beyond the apical foramen by small flexible file to prevent blockage is patency. However, this procedure might endow postoperative pain, thus maintain patency or not matter dilemma. Hence, primary objective study was compare pain between and non-patency groups secondary evaluate influence number visits, vitality teeth, group teeth preoperative ...

Evaluation of tubal patency is one the vital steps in process female infertility management. Hysterosalpingo-contrast Sonography (HyCoSy) has become first-line recommendation for evaluating patency. However, there remain some controversies and dilemmas relevant to evaluation by HyCosy, with no effective solution been proposed or consensus reached. Herein, combined previous research clinical exp...

BACKGROUND The patency and complications in aorto-iliac (AI) stenting remain poorly understood. The aim of this paper was to investigate the safety and efficacy after AI stenting. METHODS AND RESULTS This study was performed as a large-scale multicenter, retrospective registry. A total of 2,147 consecutive patients with AI disease were enrolled. The safety endpoints were procedure success, co...

BACKGROUND Although endoscopic biliary stents have been accepted as part of palliative therapy for cases of malignant hilar obstruction, the optimal endoscopic management regime remains controversial. In this study, we evaluated the safety and efficacy of placing a threaded stent above the sphincter of Oddi (threaded inside plastic stents, threaded PS) and compared the results with those of oth...

OBJECTIVE To verify the effect of location and severity of stenosis of the target coronary artery (TCA) on mid-term patency of aorta-anastomosed vs. internal thoracic artery (ITA)-anastomosed radial artery (RA) graft. METHODS During a 3-year period 228 consecutive patients received an RA graft at our institution. In 131 cases the RA was anastomosed to the aorta whereas in 97 the proximal anas...

The purpose of this study was to investigate the periapical healing process of dogs' teeth with or without apical patency and after root canal filling with two types of sealers. Forty roots of premolars and incisors were utilized. The root canals were over-instrumented and dressed with a corticosteroid-antibiotic solution for 7 days to obtain ingrowth of periapical connective tissue into the ca...
