Carotid artery stenting (CAS) is a worldwide diffuse intervention, but may be associated with distal plaque component embolization, and sometimes major and minor stroke. Statin use has been demonstrated to reduce atherosclerotic plaque burden, but its effect in reducing distal embolization during carotid stenting has not yet been well validated. ...

Endovascular treatment for hemorrhagic complications following surgery has recently gained wide acceptance due to its minimal invasiveness compared to surgery. A 56-year-old male patient underwent laparoscopic gastrectomy for gastric cancer. There were two episodes of late intraperitoneal hemorrhage and endovascular treatment was performed. Transcatheter coil embolization of the gastroduodenal artery ...

With increasing carotid artery stenting (CAS) expertise and improved CAS equipment, recent trials have demonstrated better results for CAS compared with earlier studies. As a result, it may be argued that CAS is currently non-inferior to carotid endarterectomy (CEA), at least in some patient subgroups. Consequently, there have been recent ...

Open surgical disconnection has long been the treatment of choice for dural arteriovenous fistulas (dAVFs) of the anterior cranial fossa. However, advanced patient age and the presence of medical comorbidities can substantially increase the risk of craniotomy and favor a less invasive endovascular approach. Optimal positioning within the distal ophthalmic ...
