#1
Valerie A R Juniat, Saul Rajak
The treatment of midfacial tumours with radiotherapy, chemotherapy and radio-iodine can cause nasolacrimal duct fibrosis resulting in epiphora. Nasolacrimal patency can be maintained by stenting. We report our experience of prophylatic Nunchaku stent insertion in 5 patients prior to midfacial radiotherapy. Four out of 5 patients (80%) had patent nasolacrimal ducts without any symptoms of epiphora following removal of the stents. One patient was initially asymptomatic with patent nasolacrimal duct, but subsequently developed epiphora...

BACKGROUND AND PURPOSE: Thrombus composition has been postulated to affect the success of endovascular therapy. Calcified clots are composed of large amounts of calcium phosphate which influences their mechanical properties and may serve as a model for testing this hypothesis. The aim of this study was to evaluate the recanalization and complication rates of calcified thromboemboli in patients with acute ischemic stroke who underwent thrombectomy. MATERIAL AND METHODS: A retrospective analysis was performed of all calcified intracranial thromboemboli in patients suffering an acute ischemic stroke, referred for endovascular therapy at two centers between January 2013 and July 2016...

BACKGROUND AND STUDY AIMS:  Walled-off pancreatic necrosis (WOPN) represents the major risk factor for sepsis-related multiple organ failure. Surgical debridement is an invasive approach associated with high rates of adverse events (AEs) and death. As an alternative, endoscopic ultrasound-guided cysto-gastro-anastomosis has emerged as an effective treatment for WOPNs. Recently a new dedicated-lumen apposing metal stent (LAMS) has been used with satisfactory results in treating peri-pancreatic fluid collections, including WOPNs...

OBJECTIVE: Previous evidence suggested that intravascular ultrasound (IVUS) guidance could improve outcomes after drug-eluting stents (DES) placement, largely driven by data from observational studies. We, therefore, performed a meta-analysis and trial sequential analysis of randomized controlled trials to overcome this limitation. RESULTS: The retrieval process yielded 7 RCTs with 3,192 patients. Compared to the angiography guidance, IVUS-guided DES implantation was associated with a significant reduction in the major adverse cardiac events (MACE) (OR 0...

This review discusses modern therapeutic interventions for acute ischemic stroke with a focus on endovascular therapy. In 2015, the American Heart Association (AHA) made major changes to the guidelines for the endovascular treatment of acute ischemic stroke. The Class IA indications for endovascular therapy of stroke patients include symptom onset within 6 hours, proven large vessel occlusion of an artery in the anterior circulation, and the use of a stent retriever as part of the mechanical thrombectomy. Advanced perfusion imaging helps identify patients with a low ratio of ischemic core to salvageable penumbra...

A 69 year old male, with a previous percutaneous revascularization of the mid-circumflex with a bare metal stent in 2007 was admitted to our centre for unstable angina. The angiography showed a severely calcified coronary tree with a functionally severe plaque on the proximal left anterior descending artery (LAD) and a critical focal lesion on the proximal right coronary artery. After a high pressure predilation on the proximal LAD, the balloon ruptured causing a retrograde LAD-left main (LM) dissection that was rapidly sealed with three overlapping zotarolimus-eluting stents from medial LAD to LM...

BACKGROUND: The average life expectancy is increasing worldwide, surpassing 80 years in some countries. Recently, mechanical thrombectomy (MT) using modern devices and techniques has led to improved clinical outcomes following acute ischemic stroke. However, thus far, it remains uncertain whether MT is effective in elderly patients aged over 80 years. METHODS: Between July 2013 and June 2016, 207 patients with acute ischemic stroke in the anterior circulation received MT at our center...

Stroke is the second leading cause of death worldwide and in Europe. Even with gold standard medical management of acute ischemic stroke, which is intravenous (IV) thrombolysis by administration of recombinant tissue plasminogen activator (rt-PA), the mortality rate remains the same. Intra-arterial (IA) thrombolysis therapy also did not achieve significant results and was not approved by the US Food and Drug Administration (FDA) because of limited sample size. This encouraged scientists and engineers to develop endovascular clot retrieval devices for the mechanical recanalization of the occluded arteries in stroke patients...

BACKGROUND AND PURPOSE: The clinical benefit of endovascular stroke therapy has been demonstrated in several prospective randomized trials. However, in a relevant percentage of patients, mechanical thrombectomy bears the risk of causing new infarction in initially unaffected vascular territories through thrombus fragmentation and migration of clot debris. The goal of this study was to evaluate the use of the balloon guide catheter (BGC) to effectively achieve flow arrest and thrombus aspiration during the intervention to avoid distal embolization...
