Endovascular Management, with the Use of Solitaire Stent as the First-Line Treatment for Cerebral Vasculitis: A Case Report
2019
Cerebral vasculitis that comprises a group of noninfectious inflammatory vasculitides, can produce a variety of neurologic events, including also life-threatening ones. In this paper we describe the case report of a 37-year-old female patient with cerebral vasculitis manifesting as ischemic stroke of the left cerebral hemisphere. Her clinical status deteriorated, despite immunosuppression. CT angiography demonstrated several occlusions of intracranial arteries. We describe details of endovascular revascularization of intracranial arteries in this patient, with focus at the use of the Solitaire stent, which seems to be particularly useful in such challenging cases. After endovascular repair …

Acute aortic dissection debut as STEMI: A case report
2014
Abstract We submit a case report of a 66-year-old male, with hypertension and family history of cerebrovascular disease, who was referred to our department for right-inferior STEMI. According to the current ESC (European Society of Cardiology) guidelines for the management of STEMI, the patient was conducted to the cath lab to perform primary PCI. Despite the identification of the culprit lesion we had many difficulties during the procedure of angioplasty, so we decided to perform aortography that showed a Stanford type A acute aortic dissection involving the ostium of right coronary artery causing the right-inferior STEMI. In the early phase of a STEMI, exclusion of the presence of aortic …
High-frequency rotational ablation following failed percutaneous transluminal coronary angioplasty.
1994
Percutaneous transluminal coronary angioplasty (PTCA) failed in 29 of 1,150 patients (2.5%) after successful passage of the guide wire. The reasons for failure were inability to pass the lesion with a balloon in 28 patients and inability to dilate the lesion in 1 patient. In these patients (15 stenoses and 14 chronic occlusions) rotational ablation was performed. We were able to pass the burr through the lesion in all of them, resulting in a reduction of diameter stenosis from 87 +/- 15 to 51 +/- 18%. Rotational ablation alone was initially successful (stenoses reduction > 20% and residual stenoses < 50%) in 15 of 29 (52%) patients. Additional PTCA was performed in 21 of 29 (72%) patients, …
Imaging in the catheterization laboratory
1993
Recent work confirms that visual assessment of the effect of widely employed coronary interventions is highly inaccurate. Rapid and reliable on-line angiographic quantitation is a useful advance, but problems in the application of the technique are encountered in a substantial number of cases. New algorithms have been devised to provide a comprehensive assessment of the geometry and likely functional significance of lesions as well as an objective evaluation of lesion morphology, and recent work has provided the framework for the quantitation of diffuse disease. Studies with intravascular ultrasound confirm the inadequate sensitivity of angiography in demonstrating mild to moderate atheroma…
Primary endpoint results of the OMEGA Study: One-year clinical outcomes after implantation of a novel platinum chromium bare metal stent.
2014
Bare metal stents (BMS) have similar rates of death and myocardial infarction (MI) compared to drug-eluting stents (DES). DES lower repeat revascularization rates compared to BMS, but may have higher rates of late stent thrombosis (ST) potentially due to impaired endothelialization requiring longer dual anti-platelet therapy (DAPT). OMEGA evaluated a novel BMS designed to have improved deliverability and radiopacity, in comparison to currently available platforms.OMEGA was a prospective, multicenter, single-arm study enrolling 328 patients at 37 sites (US and Europe). Patients received the OMEGA stent (bare platinum chromium element stent) for the treatment of de novo native coronary artery…
Recanalization of Totally Occluded Coronary Vessels by Percutaneous Transluminal Coronary Angioplasty
1986
Since its introduction in 1977, percutaneous transluminal coronary angioplasty (PTCA) has become an effective approach for treatment of patients with single-vessel disease [1–3, 5]. Treatment of double- and multiple-vessel disease has also been attempted [5, 6]. In patients with angina pectoris total occlusion of coronary vessels is found, and PTCA has also been used in an attempt to restore coronary blood flow in such patients [8, 10]. Even main stem occlusions have been recanalized [11]. In patients with total occlusion of coronary vessels, collateral flow is sufficient to maintain cardiac function at rest but not during exercise [12–14]. Therefore, PTCA seems to be an ideal method for re…
Langzeitverlauf über 10 Jahre nach Ballondilatation bei stabiler und instabiler Angina pectoris
2008
OBJECTIVE To assess the cardiac status of patients ten years after percutaneous transluminal coronary artery angioplasty (PTCA). PATIENTS AND METHODS Data of 534 patients (436 men, 98 women; mean age 53.2 +/- 8 years) in whom a PTCA had been performed between 1983 and 1986 were analysed, based on a questionnaire answered 121 +/- 11 months after the initial procedure. At the time of PTCA 184 patients (35%) had unstable angina, 350 (65%) stable angina. RESULTS 116 patients (63%) with unstable angina and 164 (47%) with stable angina had at least one cardiac event after the initial PTCA (repeat PTCA, bypass operation, myocardial infarction, death). None of these events occurred in 68 patients (…
Prognostic role of endothelial dysfunction and carotid intima-media thickness in patients undergoing coronary stent implantation
2009
Aim. Impaired endothelial function and increased carotid intima-media thickness are key events in the atherosclerotic process and predict future cardiovascular events in subjects with and without coronary artery disease. The purpose of this study was to investigate whether the vasodilator response to increased flow in the brachial artery and the presence of carotid lesions may have a prognostic significance for in-stent restenosis in patients undergoing coronary angioplasty. Methods. The study population included 58 patients undergoing percutaneous coronary intervention (PCI) with stenting and at least 10 months of follow-up. All patients underwent ultrasound detection of brachial artery re…
