Capsule endoscope aspiration into the respiratory tract is a rare complication of capsule endoscopy. Despite the potential seriousness of this complication, no accepted methods exist to accurately predict and therefore prevent it. We describe the case of an 85-year-old male who presented for evaluation of iron deficiency anemia. He complained of dysphagia while ingesting a patency capsule, with...

INTRODUCTION Factors such as complex root canal anatomy and the vapor lock phenomenon have been shown to limit the penetration of irrigating solutions into the apical third in both in vivo and in vitro studies involving small and wide canals. Hence, the aim of this study was to determine whether the use of a patency file is related to the presence of a radiopaque irrigating solution in the apic...

Aims The purpose of this study was to validate ST segment resolution as a non-invasive marker for patency of the infarct-related artery 90 min after the start of streptokinase therapy in patients with acute myocardial infarction. Methods and Results In the HIT-4 angiographic substudy, 447 patients with acute myocardial infarction </=6 h received 1.5 million IU streptokinase. Angiograms of the i...

BACKGROUND The aim of the present study was to assess the long-term graft patency rate of the radial artery (RA), in comparison to the saphenous vein (SV) in patients harvested for both vessels. METHODS AND RESULTS RA and SV were concomitantly used for coronary artery bypass grafting in 318 patients in an 8-year period from January 2002 to March 2010. During follow-up, graft patency was asses...

Introduction: In keeping with established international guidelines our institute follows an “all-autogenous” approach with regard to hemodialysis access. Upper arm transposition fistulas can allow for access options when forearm autogenous options are not suitable. We evaluate our experience with a single staged brachio-basilic arteriovenous fistulas (BBAVF) to assess efficacy and patency. Meth...

Purpose: To investigate outcomes following treatment of thrombosed native dialysis fistulas with AngioJet thrombectomy. Materials and Methods: We retrospectively reviewed an existing database and included patients according to the following criteria: thrombosed fistula, native fistula, and use of the AngioJet system for mechanical thrombectomy. Outcomes included clinical success, complications,...

OBJECTIVE To determine the effects of smoking, plasma lipids, lipoproteins, apolipoproteins, and fibrinogen on the patency of saphenous vein femoropopliteal bypass grafts at one year. DESIGN Prospective study of patients with saphenous vein femoropopliteal bypass grafts entered into a multicentre trial. SETTING Surgical wards, outpatient clinics, and home visits coordinated by two tertiary ...

Objectives. We sought to examine the relation between time to treatment and 90-min patency rates in patients receiving intravenous streptokinase (SK) or accelerated tissue-type plasminogen activator (t-PA). Background. Early patency of the infarct-related artery is a major determinant of survival after thrombolysis for acute myocardial infarction. Some data suggest that time to treatment may in...

BACKGROUND Although concern regarding patency and possible compromise of graft blood flow by routing the right internal thoracic artery (RITA) through the transverse sinus has been raised, little is known about long-term patency. METHODS AND RESULTS To evaluate long-term patency of in situ RITA bypass via the transverse sinus, our first 115 patients (94 men, 21 women; mean age, 62.5 years; ra...
