Basilar artery occlusion has a poor prognosis, but intra-arterial revascularization therapy has been shown to improve outcome. We report the case of a 32-year-old patient who suffered recurrent basilar artery occlusion and was successfully treated first with mechanical and pharmacological thrombolysis, then with stenting, in 2 separate angiographic sessions. An ...

Coronary artery perforation (CAP) is an infrequent yet a very dangerous complication of percutaneous coronary intervention. We describe the successful treatment of a guidewire-induced distal coronary branch vessel perforation using localized distal injection of intracoronary thrombin with a microcatheter. This technique appears to be safe and effective for the treatment ...

BACKGROUND:: Cerebral vasospasm (VSP) is a major cause of morbidity and mortality associated with subarachnoid hemorrhage (SAH). The current endovascular paradigm for vasospasm refractory to medical therapy is to perform angioplasty for proximal vessel VSP, and vasodilator infusion for distal vessel VSP. OBJECTIVE:: The authors report their experience of a ...

Endovascular repair of inflammatory aortic aneurysms has been reported as an alternative to open surgical treatment. In selective cases, adjunctive bypass surgery may be required to provide an adequate landing zone. We report a case of endovascular repair of an inflammatory aortic aneurysm in a patient with Behçet's disease using ...

The serine protease inhibitor antithrombin III (AT-III), an α2-globulin synthesized in the liver and endothelial cells, is the principal in vivo inhibitor of blood coagulation inactivating mainly thrombin. AT-III deficiency presents a rare hereditary or acquired disorder that most often comes to light when a patient suffers recurrent venous thrombosis ...

Subintimal angioplasty (SA) is becoming increasingly accepted as a revascularization technique for chronic arterial occlusive disease. However, its efficacy in iliac artery occlusions has not been established. Therefore, we investigated the procedural and clinical outcomes of subintimal angioplasty in long iliac artery occlusions and compared them with those of intraluminal ...

Abstract Late stent thrombosis represents a life-threatening event, usually triggered by inadequate antiplatelet therapy and promoted by multiple risk factors, such as stenting of a chronic total occlusion, overlapping stenting, an abnormal vascular response to the eluted drug, stent malapposition and stent fracture. A 57-year-old man with aspirin hypersensitivity underwent ...

Percutaneous intervention carries a higher risk of distal embolization and poorer outcome in saphenous vein grafts (SVG) than in native coronary vessels. Embolic protection devices (EPD) have demonstrated value in decreasing the risk of embolization and post-procedural enzymes elevation after SVG intervention. Although there is ample evidence to support the ...

BACKGROUND:: The anterior communicating artery (AcoA) aneurysm is one of the most challenging aneurysms. As endovascular techniques evolve, a remaining challenge is the reduction of complications related to the surgical approach. Although the endonasal approach is widely used for pituitary adenomas and is increasingly popular for suprasellar tumors, only two ...

The primary aim of this study is to assess the value of intraoperative near-infrared indocyanine green videoangiography (ICGA) during intracranial aneurysm surgery. Altogether, 129 patients harboring 152 intracranial aneurysms were recruited in this study between March 2007 and December 2008 and the clinical data were retrospectively analyzed. Intraoperative ICGA was ...

Patients with acute iliofemoral deep venous thrombosis often experience severe postthrombotic complications that result from venous obstruction and valve incompetence. Conventional anticoagulation prevents thrombus extension, fatal pulmonary embolism, and recurrence of the deep venous thrombosis, but it can hardly minimize the postthrombotic complications. Whether early thrombus removal significantly reduces the ...

The gold standard for the treatment of abdominal aortic infections remains controversial. Cryopreserved arterial homografts and silver-coated Dacron grafts have both been advocated as reasonable grafts. Direct clinical or experimental comparisons between these two treatment options have not been published before. This study compared cryopreserved arterial homografts and silver-coated Dacron ...

BACKGROUND AND IMPORTANCE:: Galenic dural arteriovenous fistulas (DAVFs) are a subtype of the rare falcotentorial DAVFs with a high risk of hemorrhage and an aggressive clinical course. Microsurgical treatment is often necessary because endovascular obliteration will rarely completely obliterate the DAVF. CLINICAL PRESENTATION:: We present a unique case of a ...

A traditional method for internal jugular vein catheterization has been through the transjugular approach. These days, ultrasound-guided cannulation is the preferred mode because of the higher success and lower complication rates. Complications associated with the transjugular approach include neck hematoma caused by carotid artery puncture, pleural puncture leading to pneumothorax ...

Arteriovenous (AV) shunts are relatively uncommon in the liver and usually associated with advanced hepatocellular carcinoma (HCC). In patients with massive AV shunts complicating advanced HCC, transarterial chemoinfusion therapy is not effective because chemotherapeutic agents go through the shunts and may cause systemic toxicity as well as decrease the chemotherapeutic ...
