INTRODUCTION Procedural accidents have a negative effect on healing and might contribute to the persistence of infections in inaccessible apical areas, requiring surgical intervention. This report describes a case of persistent apical periodontitis of a lower left first molar associated with the sinus tract and a periapical lesion that required nonsurgical endodontic retreatment and apical surg...

Background: Intravenous thrombolytic therapy is still the most common treatment for acute myocardial infarction (AMI) in our country. In recent years, some cases of suboptimal results of the treatment with a special trademark (Heberkinase) have been reported. So, we decided to evaluate the patency rate of arteries involved in infarction after treatment with Heberkinase. Materials and Methods:...

Background: Peripheral arterial disease is a source of morbidity and mortality. Surgical vascular reconstruction is a treatment option but probability of failure and complications are important concerns. In this study, we evaluated outcome of surgical infrainguinal reconstruction and factors affecting graft patency for a period of one year. Methods: In this cohort study, 85 consecutive patie...

statement of problem: endodontic treatment of necrotic teeth with open apices is a challenge. after ruling out surgery as a treatment scheme and introduction of the multivisit apexification which in turn had its disadvantages, apical plug seems to be a suitable substitute treatment plan for such cases. apical plug makes the treatment through formation of a barrier against the obturating materia...

introduction: for a successful root canal treatment, canal must be obturated apically, coronally and laterally to prevent microleakage and canal reinfection. cold lateral condensation is the most popular method of canal obturation; an easy method with a controlled filling. cold lateral technique disadvantages are presence of void, possible vertical root fracture, and absence of a homogenous and...

abstract: introduction & objective: in patients with chronic renal failure who need chronic hemodialysis, av fistula is one of the most proper ways of vascular access. the aim of this study was to assess the patency and complications of av fistulas in patients with chronic hemodialysis. materials & methods: in this descriptive study 82 patients with chronic renal failure, who underwent av fistu...

conclusions this case raises awareness on the lack of visualization of ureteral flux during conventional cystoscopic evaluation in patients with renal failure undergoing pelvic organ prolapse repair, while also emphasizing the importance of confirming ureteral patency via retrograde ureteral intubation when cystoscopy is non-diagnostic. background pelvic floor reconstruction can result in obstr...

background dialysis vascular access complications are considered as significant causes of morbidity in chronic hemodialysis patients. objectives the aim of the present study was a comparison of axillary loop and straight grafts patency and its complications in hemodialysis access. patients and methods in this cohort study conducted at shahid beheshti medical university, 77 patients who underwen...
