The majority of surgeons leave internal stents following laparoscopic pyeloplasty, which necessitates a second anaesthetic for removal. A novel technique of placing external nephro-ureteric stents, thus obviating a second procedure for retrieval, is shown in this video bank. As demonstrated in the video, a Kirschner wire (K-wire) is used to thread the stent in place. Although, there are few reports of using externalised stents in laparoscopic pyeloplasty, it is believed that this technique has not been previously described...

PURPOSE: In mechanical thrombectomy (MT) for ischemic stroke, endothelial cells (ECs) from intracranial blood vessels adhere to the stent retriever device and can be harvested. However, understanding the molecular biology and the role of the endothelium in different pathological conditions remains insufficient. The purpose of the study was to characterize and analyze the molecular aspect of harvested ECs using cell culture and transcriptomic techniques in an MT swine model relevant to clinical ischemic stroke...

PURPOSE: Stent-retriever thrombectomy (SRT) for acute intracranial large artery occlusion (LAO) may not result in permanent recanalization in rare cases, e.g. due to an underlying stenosis or dissection. In this specific patient group, rescue stent angioplasty (RSA) may be the only treatment option to achieve permanent vessel patency and potentially a good clinical outcome. To date, the experience with RSA is limited. METHODS: In this retrospective analysis, interventional and clinical data of patients with acute intracranial LAO of the anterior and posterior circulation who underwent RSA after SRT due to an underlying lesion between 2012-2017 in four neurovascular centers were studied...

BACKGROUND: Despite evidence from individual studies suggesting that prolonged inflation improves coronary stent expansion, relatively shorter inflation times are commonly employed in clinical practice. METHODS: We performed an electronic search of PubMed, Web of Science, Cochrane, and CINAHL databases to retrieve outcome studies comparing prolonged versus short inflation times during stent deployment. Outcomes studied included minimal stent diameter (MSD) and minimal stent area (MSA)...

A 48-year-old female with a symptomatic giant carotid cavernous aneurysm underwent endovascular treatment with multiple Pipeline Flex embolic devices (PED). The delivery catheter had to take a complicated course of multiple turns to cross the aneurysm, and its loop was tied in the aneurysm. When the catheter was to be withdrawn, it was apparent that the tied catheter had made a tight knot that bound the tail of the previous PED together. We successfully retrieved all of the system including the tied PED, and we used telescoping stents with five PEDs in the next operation...

Stent-retriever thrombectomy for atherosclerotic acute occlusion of cerebral arteries is difficult. We experienced three patients with middle cerebral artery atherosclerotic occlusion who achieved successful recanalization with the combined use of aspiration thrombectomy devices and cerebral angioplasty balloons. The combination is feasible in terms of smooth delivery of the balloon catheter.
