The preoperative assessment of stroke risk in lesions involving the internal carotid artery.
1995
Patients with vascular or tumourous lesions involving the internal carotid artery are at risk of damage or occlusion of this vessel during surgical or endovascular procedures. To assess the stroke risk transcranial Doppler aided carotid compression tests were performed in 82 patients. Based on changes of blood flow velocity (BFV), pulsatility index, systolic/diastolic ratio and length of transient hyperaemic response three groups could be differentiated. Patients in group A (31%) showed only a slight reaction of BFV and were at minimal risk in case of carotid occlusion. Patients in group B (52%) underwent a distinct decrease of Doppler readings with partial improvement and were considered t…
Artery occlusion independently predicts unfavorable outcome in cervical artery dissection
2020
ObjectiveTo assess the impact of dissected artery occlusion (DAO) on functional outcome and complications in patients with cervical artery dissection (CeAD).MethodsWe analyzed combined individual patient data from 3 multicenter cohorts of consecutive patients with CeAD (the Cervical Artery Dissection and Ischemic Stroke Patients [CADISP]–Plus consortium dataset). Patients with data on DAO and functional outcome were included. We compared patients with DAO to those without DAO. Primary outcome was favorable functional outcome (i.e., modified Rankin Scale [mRS] score 0–1) measured 3–6 months from baseline. Secondary outcomes included delayed cerebral ischemia, major hemorrhage, recurrent CeAD…
Epileptic seizures and cerebrovascular disease
1989
- A series of 88 patients with completed stroke was selected in which heralding, early and late seizures were distinguished according to their onset. Relationships between CT scan and clinical EEG data are discussed with particular emphasis on possible mechanisms of seizures. Thus, small emboli or haemodynamic factors are stressed in the cases of heralding seizures, metabolic disturbances with cytotoxic effects in early seizures and chronic epileptic focus in late seizures.
Morbidity in 565 Type 2 Diabetic Patients According to Stage of Nephropathy
1998
Between 1988 and 1992, 565 type 2 diabetic patients were examined for nephropathy and diabetes-associated diseases during hospital treatment. Stages of nephropathy were defined as no clinical sign of nephropathy (N = 280), microalbuminuria (N = 38), overt proteinuria (N = 105), impaired renal function (N = 55), and chronic dialysis therapy (N = 87). In dialyzed patients, HbA1c averaged 6.8%, and, in the other groups, HbA1c was between 7.6% and 8.3% (normal range, 3.8%-6.1%). Cataract was not associated with the severity of nephropathy. Stroke was most common in the stage of renal insufficiency (34%). The following complications, as found in medical history or as current event, showed a sign…
Acute Cerebrovascular Disease in the Young
2013
Background and Purpose— Strokes have especially devastating implications if they occur early in life; however, only limited information exists on the characteristics of acute cerebrovascular disease in young adults. Although risk factors and manifestation of atherosclerosis are commonly associated with stroke in the elderly, recent data suggests different causes for stroke in the young. We initiated the prospective, multinational European study Stroke in Young Fabry Patients (sifap) to characterize a cohort of young stroke patients. Methods— Overall, 5023 patients aged 18 to 55 years with the diagnosis of ischemic stroke (3396), hemorrhagic stroke (271), transient ischemic attack (1071) we…
Correlation between mortality trends of ischaemic cardiopathy and some nutritional factors in Spain 1968?1986
1992
After describing the evolution of mortality from ischaemic cardiopathy (IC) in Spain from 1951 to 1986, which is tending to stabilize in some age groups, and from cerebrovascular accidents (CVA), which is clearly declining, an attempt is made to relate these developments to the prevalence of the main risk factors (hypertension, cholesterol, tobacco) associated with IC and CVA. Certain advances, though of a limited number, have been made in recent years in the control of arterial hypertension in Spain, although campaigns on a national scale as in other countries have not been carried out. Regarding alimentary factors, there is an obvious increase in the consumption of food rich in proteins a…
The Prevalence of Chronic Cerebrospinal Venous Insufficiency in Meniere Disease: 24-Month Follow-up after Angioplasty
2016
Abstract Purpose To evaluate relationship between Meniere disease (MD) and chronic cerebrospinal venous insufficiency (CCSVI) using ultrasound, magnetic resonance (MR) imaging, and venography and to evaluate the effectiveness of angioplasty of the internal jugular vein (IJV) and azygos vein (AV) in reducing symptoms of MD. Materials and Methods Patients with a confirmed diagnosis of MD unresponsive to standard treatment underwent duplex ultrasound and MR imaging to diagnose CCSVI. Healthy volunteers were also studied to evaluate CCSVI in asymptomatic subjects. Patients with CCSVI and MD underwent venography and percutaneous transluminal angioplasty (PTA) of IJV and AV. Results There were 18…
Evaluation of collateral flow capacity in patients with vascular or tumorous lesions of the skull base by Doppler sonography
1991
In 12 patients with vascular or tumorous lesions of the skull base, the collateral flow capacity was examined by transcranial Doppler sonography and carotid compression studies. In four patients no cross flow mechanism was found, in two patients the test remained unclear, and in six patients the examination suggested a good collateral flow capacity. However, for this application of Doppler sonography no borderlines have yet been defined and thus interpretation is difficult. Intraoperative Doppler sonography was used in five patients and proved to be helpful for localisation of the internal carotid artery within skull base tumors.
Thrombin-antithrombin III complexes in type II diabetes mellitus.
1992
Several studies suggest that diabetes is associated with a hypercoagulable state. Therefore determination of thrombin-antithrombin complex (TAT) could represent a sensitive parameter for specific detection of a latent activation of the clotting system. The present study documents increased plasma TAT in a heterogeneous group of non-insulin-dependent diabetic patients. The finding of increased TAT levels both in diabetic patients with vascular complications and in vascular disease patients without diabetes suggests a relationship between existing vascular disease and the hemostatic mechanism that produces augmented thrombin activity. In acute vascular occlusions the presence of diabetes seem…
Cardiovascular events among reproductive and menopausal age women with polycystic ovary syndrome: a systematic review and meta-analysis
2019
This study aimed to evaluate the prevalence (P)/hazard ratio (HR) of cardiovascular (CV) events among reproductive age and menopausal age women with polycystic ovary syndrome (PCOS) in comparison with healthy controls. PubMed, Scopus, ScienceDirect, Web of science, and Google scholar were searched for retrieving observational studies published up to April 2018 investigating CV events in patients with PCOS. The primary outcomes were a composite outcome of CV events [including coronary arterial disease (CAD), cardiovascular disease (CVD), myocardial infarction (MI), angina, heart failure, and ischemic heart disease] and mortality due to CV events; secondary outcomes were specific CVD events, …
