Flow-diverting stents have demonstrated great promise for the treatment of cerebral aneurysms; however, clinical experience with the devices remains very preliminary. We present two cases of spontaneous delayed complications-one fatal aneurysm rupture and one symptomatic increase in aneurysm volume-following the treatment of intradural aneurysms with the Pipeline Embolization Device (PED). ...

Introduction Endovascular coil embolization has an established role alongside microsurgical clipping in the treatment of aneurysms. We studied previously clipped aneurysms that presented as subarachnoid hemorrhage and were treated by coil embolization. Methods A retrospective review was performed of two prospectively maintained databases from two institutions (Cleveland Clinic, Emory University) ...

Background Spontaneous fusiform aneurysms of the middle cerebral artery (sfaMCA) are quite uncommon and tend to occur in young adults. The use of superselective angiography for ruptured and unruptured aneurysms can help delineate vital angioarchitecture and assist with perioperative planning and treatment modality. The use of superselective Wada testing (SWT) ...

Endovascular coiling has become the primary treatment modality for the treatment of intracranial ruptured aneurysms in many centers. A multicenter randomized controlled trial (RCT), ISAT study, has demonstrated that endovascular coiling of ruptured intracranial aneurysms has benefits over surgical clipping in those patients suitable for either treatment. Because RCT comparing ...

The present case illustrates pulmonary vein isolation guided by real-time three-dimensional transesophageal echocardiography. This imaging modality allowed to navigate in a point-by-point fashion around pulmonary veins to assess both catheter location in relation to pulmonary vein ostia and stability of catheter tip. Also, it offered high-resolution visualization of a thickened, ...

Introduction Current models for the endovascular treatment of aneurysms often require the use of adjuvant devices. Balloon-assisted techniques require temporary occlusion of the parent vessel. Intravascular stents require the use of antiplatelet medication. A novel device that achieves temporary neck protection without parent vessel occlusion or antiplatelet medication is examined ...

Pseudo aneurysm (PSA) of femoral artery is the second common post puncture complication. If PSA is less than 18 mm, it can be closed spontaneously and it can be asymptomatic. If not, it needs treatment. The most common non invasive method used in the treatment is ultrasound guided compression (UGC) ...

Conventional absolute contraindications to catheter-directed thrombolysis include active or recent hemorrhage and the presence of local vascular infection, both of which increase the risk of procedure-related complications such as bleeding and systemic sepsis. For this reason, lytic therapy of arterial thromboembolism under these circumstances is generally precluded. Herein, we describe ...

The combination of anomalous left coronary artery origin from the pulmonary artery and an accessory pathway has not been reported previously in the medical literature. In medicine, the coexistence of two clinical causes can lead to the same clinical findings, and this can make the researcher's attempt to distinguish between ...

Pulmonary embolism is a common condition with a high mortality. We describe a previously healthy 68-year-old male who suffered three pulmonary embolisms during a short period of time, including two embolisms while on anticoagulant treatment. This paper illustrates three important points. (1) The importance of optimal anticoagulant treatment in the ...

Aneurysm treatment using flow diversion could become the treatment of choice in the near future. While such side-wall aneurysm treatments have been studied in many publications and even implemented in selected clinical cases, bifurcation aneurysm treatment using flow diversion has not been addressed in detail. Using angiographic imaging, we evaluated ...

Coronary artery bifurcations are regions where the atherosclerotic plaque appears more frequently and where the percutaneous treatment is more challenging. To analyze these important vascular regions, in this paper is proposed a method for the extraction of realistic 3D models of coronary bifurcations combining information from pre operative computer tomography ...

The results of endovascular treatment of symptomatic intracranial arteriosclerotic stenosis with stenosis grades exceeding 70% show a mortality rate of 2% and severe morbidity of 8.3%. This justifies treatment being performed by experienced interventionalists only in selected cases, if the prospective outcome of pharmacotherapy alone indicates a higher risk (i.e., ...

Cerebral vasospasm complicating aneurysmal subarachnoid hemorrhage is a well-known medical entity. The delayed ischemic neurological deficits (DIND) as a result of vasospasm remain the main cause of morbidity among patients who manage to survive this severe disease pattern. When the traditional treatment options, either medical or interventional, fail to reverse ...

Based on numerous reports citing high sensitivity and specificity of non-invasive imaging [e.g. computed tomography angiography (CTA) or magnetic resonance angiography (MRA)] in the detection of intracranial aneurysms, it has become increasingly difficult to justify the role of conventional angiography [digital subtraction angiography (DSA)] for diagnostic purposes. The current literature, ...

Recanalization of acute large artery occlusions is a strong predictor of good outcome. The development of thrombectomy devices resulted in a significant improvement in recanalization rates compared to thrombolytics alone. However, clinical trials and registries with these thrombectomy devices in acute ischemic stroke (AIS) have shown recanalization rates in the ...

Intracranial aneurysms are present in roughly 5% of the population, yet most are often asymptomatic and never detected. Development of an aneurysm typically occurs during adulthood, while formation and growth are associated with risk factors such as age, hypertension, pre-existing familial conditions, and smoking. Subarachnoid hemorrhage, the most common presentation ...

First generation drug-eluting stents (DES) have significantly improved the treatment options for patients with symptomatic coronary artery disease by decreasing rates of restenosis after percutaneous coronary revascularisation procedures. However, early enthusiasm was tempered by reports of late stent thrombosis, primarily in "off-label" use. In particular, the treatment of atherosclerotic plaques ...

Pulmonary veins (PVs) usually drain into the left atrium (LA) and are frequently targeted for electrical isolation, since it became evident that PVs may trigger and maintain paroxysmal atrial fibrillation (AF). We present a patient with right-sided PVs anomalously connecting to the right atrium with lack of electrical PV-atrial connection. ...

Obese subjects with orthopedic trauma exhibit increased inflammation and an increased risk of pulmonary edema. Prostaglandin E(2) (PGE(2) ) production is elevated during inflammation and associated with increased vascular permeability. We hypothesize that pulmonary edema in obesity following orthopedic trauma is due to elevated PGE(2) and resultant increases in pulmonary ...

Postobstructive pulmonary edema is life-threatening, and results from a sudden episode of upper airway obstruction. Croup is generally thought to be a benign condition, but occasionally it can develop into postobstructive pulmonary edema. We present a case of a 5-year-old boy with recurrent croup, who was diagnosed with postobstructive pulmonary ...

Giant basilar tip aneurysms are a challenge to treat because of the complex anatomy and critical vessels that arise in this region. For large aneurysms, with multiple recurrences after coiling, when microsurgical clipping is not possible, a bypass to the posterior cerebral artery (PCA) can be helpful in providing definitive ...

Acute cardiogenic pulmonary edema (ACPE) is a common cardiogenic emergency with a quite high in-hospital mortality rate. ACPE is defined as pulmonary edema with increased secondary hydrostatic capillary pressure due to elevated pulmonary venous pressure. Increased hydrostatic pressure may result from various causes including excessive administration of intravascular volume, obstruction ...
