The clinical relevance of the transient intraluminal filament model of middle cerebral artery occlusion (tMCAO) has been questioned due to distinct cerebral blood flow profiles upon reperfusion between tMCAO (abrupt reperfusion) and alteplase treatment (gradual reperfusion), resulting in differing pathophysiologies. Positive results from recent endovascular thrombectomy trials, where the occlud...
In 2013, there were three major trials that were published comparing outcomes of treatment of acute ischemic stroke with IV tPA to interventional methods: IMS III, MR RESCUE, and SYNTHESIS. These trials concurrently failed to show the superiority of endovascular therapy compared to IV tPA for the treatment of acute ischemic stroke. There has been much discussion following the publication of the...
Acute revascularization is associated with improved outcomes in ischemic stroke patients. It is unclear which method of intra-arterial intervention, if any, is ideal. Promising approaches in acute stroke treatment are likely a combination of intravenous and endovascular revascularization efforts, combining early treatment initiation with direct clot manipulation and/or PTA/stenting. In this rev...
Aortic dissection is a cardiovascular event of high mortality if not early diagnosed and properly treated. In Stanford type A aortic dissection, there is the involvement of the ascending aorta, whereas in type B the ascending aorta is not affected. The treatment of type A aortic dissection is mainly surgical. The hospital mortality of type B aortic dissection surgical treatment is approximately...
OBJECT Spinal dural arteriovenous fistulas (DAVFs) are the most common spinal vascular malformations and can be a significant cause of myelopathy, yet remain inefficiently diagnosed lesions. Over the last several decades, the treatment of spinal DAVFs has improved tremendously due to improvements in neuroimaging, microsurgical, and endovascular techniques. The aim of this paper was to review th...
BACKGROUND AND PURPOSE The long-term outcome of endovascular intervention compared with best medical management of patients with symptomatic vertebral artery stenosis is uncertain. We therefore compared these treatments in a randomized trial with long-term follow-up. METHODS In the international, multicenter Carotid And Vertebral Artery Transluminal Angioplasty Study, 16 patients with symptom...
BACKGROUND AND PURPOSE Intracranial aneurysms are common, with an overall frequency ranging from 0.8% to 10%. Because prognosis after subarachnoid hemorrhage is still very poor, treatment of unruptured aneurysms, either neurosurgically or endovascularly, has been advocated. However, risk of rupture and subsequent subarachnoid hemorrhage needs to be considered against the risks of elective treat...
Tracheoinnominate artery fistula (TIF) is one of the most dangerous complications after tracheostomy, and fetal even after surgical repair. Recently, endovascular stent has been introduced as an option for the treatment of TIF. Unfortunately, endovascular stent repair could not replace the surgery due to rare clinical reports about the long-term follow-up and complications of stent graft. More ...
Cases of an endovascular treatment for traumatic aortic injury are extremely rare. A prompt diagnosis of traumatic thoracic aortic pseudoaneurysm through a 3-dimensional computed tomographic angiography of aorta and emergency repair are mandatory to rescue the life-threatening condition. An endovascular treatment is a trend for traumatic aortic injury because of lower invasivity, morbidity and ...
Aortic aneurysms remain a challenging problem for patients and physicians. There have been major advances in the treatment of large-vessel aneurysms during the past 10 years. The surgical armamentarium used to treat these aneurysms now includes an endovascular approach that allows the insertion of a graft to exclude the aneurysm sac from blood flow. The endovascular repair of abdominal and thor...
