INTRODUCTION: Ureteroscopy has been shown to be a highly efficacious and safe modality for the treatment of pediatric urolithiasis. However, conventional ureteroscopy relies on fluoroscopy for intraoperative guidance, exposing both patient and operating room personnel to ionizing radiation. Pediatric urolithiasis patients are at a particularly increased risk from this radiation exposure. The use of ultrasound in place of fluoroscopy for intraoperative guidance has emerged as one modification that can reduce radiation exposure during ureteroscopy...

The use of 8-F balloon guide catheter (BGC) for proximal flow control was previously shown to prevent distal embolic complications during mechanical clot retrieval in patients with acute ischemic stroke. In this retrospective study, the utility of 8-F BGCs for proximal flow control during endovascular coiling of anterior circulation aneurysms was investigated. Patients who underwent endovascular coiling for anterior circulation aneurysms between August 2013 and December 2016 were retrospectively analyzed. Among a total of 152 patients included in this series, 64 patients presented with aneurysmal rupture, whereas the aneurysms were detected incidentally or due to mass effects in the remaining patients...

PURPOSE: To investigate the morbidity, complication rate, and pain perception during removal of a novel ureteric stent with a magnetic end using a-traumatic retrieval catheter. METHODS: Between November 2013 and July 2015, 151 consecutive patients who underwent semirigid ureterorenoscopy (URS) for stone removal were prospectively enrolled. Stent removal was performed under local anesthesia using a special magnetic-end stent remover 1 week following URS. At follow-up, we obtained patients' medical history, urine culture result, renal ultrasonogram, and visual analog scale (VAS) score regarding stent irritation (VAS 1) and pain during removal (VAS 2)...

PURPOSE: Stent retriever-based mechanical thrombectomy (MT) for emergent large vessel occlusions (ELVO) is often complicated by thrombus fragmentation causing distal embolization and embolization to new vascular territories. Well-established embolic protection approaches include proximal flow arrest and distal aspiration techniques during stent retriever maneuvers. Aiming at the reduction of thrombus fragmentation during MT we evaluated a technical approach combining proximal balloon occlusion together with direct thrombus aspiration during MT: the PROTECT technique...

BACKGROUND AND IMPORTANCE: Microguidewire entrapment and failure related to endovascular therapy is a rare complication with limited case reports available, most of which are from cardiac endovascular intervention. Migration of the microguidewire has been reported in coronary intervention with some resulting in severe complications, but there are no reported cases of spontaneous extrusion of wire fragment following a neurointerventional procedure. We report the first case of a microguidewire entrapment with subsequent fracture, followed by spontaneous extrusion of the wire fragment...

BACKGROUND: Patients with chronic kidney disease (CKD) have elevated bleeding and ischemic outcomes. We aim to assess the short- and long-term efficacy and safety of bivalirudin compared to heparin plus glycoprotein IIb/IIIa inhibitors (GPIs) in coronary artery disease (CAD) patients with CKD. METHODS: Randomized trials were searched in PubMed, Cochrane, and Embase databases up to January 2017. Among the trials retrieved, efficacy endpoints were defined as mortality, myocardial infarction (MI), repeat revascularization, stent thrombosis, and major adverse cardiac events (MACEs)...

Newer generation of self-expandable nitinol coronary stents has proven to be useful in the treatment of bifurcations, tapered vessels, thrombotic lesions, venous grafts and ectatic segments. However, optimal device positioning can be cumbersome, due to the peculiar delivery mechanism which consists of retracting an outer sheath in order to release the stent from the distal edge. We report the case of a 53-year-old man, admitted for unstable angina. Coronary angiography showed a tight stenosis of the proximal left anterior descending coronary artery...

Background: The placement of a metallic stent as a bridge to surgery (SBTS) could represents an option for the treatment of left-sided malignant colonic obstruction in centres with adequate skills. Several meta-analyses demonstrated better short-term outcomes after SBTS when compared with emergency surgery (ES); however, some studies reported a higher local recurrence rate. The aim of the present review is to investigate the long-term outcomes of stent bridge to surgery as compared to ES...

This retrospective study investigated whether the volume or density of the thrombus is predictive of recanalization in stent retriever (SR) treatment. Consecutive patients treated with SR thrombectomy as the first endovascular modality were enrolled. The thrombus volume and density were measured on thin-section noncontrast computed tomography using 3-dimensional software. The patients were grouped by recanalization status and the number of SR passes. Among 165 patients, recanalization was achieved with the first pass in 68 (50...

PURPOSE: Cardiac myxomas are common tumors of the heart with disproportionate impact on young patients, occasionally with dramatic systemic dissemination of tumor emboli with catastrophic multiorgan system ischemia. The coincident comorbidities can increase the risk of traditional treatments for tumor embolus in each region. CASE REPORT: A young patient with previously unknown cardiac myxoma presented with seizure and was found to have stress cardiomyopathy, multiple cerebral large vessel occlusions with acute ischemic stroke, bilateral lower extremity tumor emboli and rhabdomyolysis, and renal tumor embolus with acute tubular necrosis...

Vincent Zimmer
Gastroduodenal stenting using self-expandable metallic stents (SEMSs) represents a viable endoscopic option for palliative treatment of gastric outlet obstruction (GOO), less invasive relative to surgical and/or endoscopic ultrasound-guided gastroenterostomy (EUS-GE). Nevertheless, high rates of stent dysfunction remain a significant Achilles' heel of the procedure. Endoscopic removal of a distally migrated gastroduodenal stent remains challenging with single-channel techniques, calling for individually tailored solutions vis-à-vis the inevitable upstream stricture...

BACKGROUND: Embolization of thrombus fragments in new or downstream vascular territories is a potential adverse event in neurothrombectomy, requiring additional repeated thrombectomy attempts. This study aims to describe technical results of the thrombectomy with clamping embolus technique (TCET) method in acute ischemic stroke. This study also aims to evaluate the efficiency of mechanical thrombectomy by TCET, and to compare it with conventional stent retriever thrombectomy (CSRT). MATERIALS AND METHODS: A retrospective analysis was performed in 52 consecutive patients treated between January 2015 and October 2016 for intracranial large vessel occlusion by stent retriever thrombectomy...

A 71-year-old man with acute basilar artery occlusion was referred for endovascular treatment 6 hours after the onset of stroke with a Glasgow Coma Score of 3 and National Institutes of Health Stroke Scale of 27. A cerebral arteriogram revealed occlusion of the left vertebral artery proximally and thromboembolic occlusion of the basilar tip. Direct aspiration and mechanical thrombectomy with various stent retrievers failed to reconstitute arterial flow in the basilar artery. Thrombolysis in cerebral infarction 2b recanalization was achieved only after placement of double Catch Mini stent retrievers through 2 microcatheters, on both side branches of the basilar bifurcation in a kissing fashion and retrieving them simultaneously...

BACKGROUND: Cerebral hyperperfusion syndrome (CHS) is known to be a rare but devastating complication of carotid artery revascularization. Because patients with acute ischemic stroke due to acute major cerebral and/or cervical artery occlusion treated with endovascular reperfusion therapy may have impaired autoregulation in the cerebral vasculature, these patients may also develop CHS. Despite the growing number of endovascular reperfusion procedures for acute ischemic stroke, this complication has only rarely been reported...
