Die Rolle der Farbduplexsonographie bei Diagnose und Differentialdiagnose von Glomus-caroticum-Tumoren*

1996

BACKGROUND Currently the diagnosis of tumorous lesions of the carotid bifurcation is the domain of magnetic resonance imaging (MRI) and digital subtraction angiography (DSA). So far, colour Doppler imaging (CDI) has not been playing an important part in this field. The aim of this study was to define the diagnostic value of CDI in the evaluation of these tumours related to the big arteries and to compare the different imaging techniques. PATIENTS AND METHODS 6 female patients with suspected tumours of the carotid bifurcation were examined with CDI. Additionally 5 MRI examinations and 3 preoperative diagnostic DSA examinations were performed in the same patients. Pathologically, there were 4…

Neural conservation in skull base surgery

2002

Surgical treatment of lesions of the skull base carries significant risk to the functioning of the cerebral hemispheres, brainstem, and cranial nerves. This risk is due to both (1) problems associated with maintaining an adequate blood flow while exposing and removing the tumor and (2) direct or indirect trauma to the brain, perineural tissues, and cranial nerves. These risks may be reduced if information about possible implications of surgical maneuvers on the cerebral blood flow and on the function of the patient’s CNS and cranial nerves is available and can be monitored during surgery of the skull base. The use of EMG neuromonitoring for the facial nerve and of brainstem evoked response …

Transverse Small Skin Incision for Carotid Endarterectomy

2015

The purpose of this report is to determine the feasibility of short transverse skin incision (STI4 cm) for eversion (EEA) and patch (PEA) endarterectomy with or without shunt by comparing it with the outcomes after long transverse skin incision (LTI 4-8 cm).Of 164 elective consecutive patients (71 ± 2.73% symptomatic) operated at one institution over 24 months, 81 were treated with STI, while 83 patients received LTI. The LTI and STI groups did not differ in terms of age, symptoms, or risk factors. EEA or PEA under locoregional (LRA) or general (GA) anesthesia were performed.STI was associated with shorter operation times (75.19 ± 15.33 vs. 94.87 ± 41 and 99.4 ± 27.36 vs. 132.66 ± 51.32, re…

nrCBF and EEG Monitoring During Probatory Balloon Occlusion of the Internal Carotid Artery

1985

Surgical treatment of tumors in the neck and throat rounding the carotid artery or of giant aneurysms originating from this vessel often makes ligation or resection of the internal carotid artery necessary. This procedure carries a 15%–30% morbidity from cerebral ischemia according to the literature (2, 7).

Cessation of Cerebral Blood Flow in Total Irreversible Loss of Brain Function

1969

After the demonstration, by our group [3, 4], that in cases of so-called “cerebral death” there is an absence of clearance from the brain of 133Xe selectively injected into the internal carotid artery, further attention was dedicated to establish possible sources of error in this technique.

Risk and Benefit of STA/MCA Anastomoses

1985

The advantage of EC/IC operation has not yet been proved unequivocally enough. We therefore attempted to analyze our cases in order to establish the possible benefit and risk of the operation. We compared the outcome of the operated and nonoperated patients with reference to the literature.

Safety and efficacy of endovascular treatment for carotid artery stenoses using proximal protection systems : 30-day follow-up

2017

Introduction. Although surgical endarterectomy remains the treatment of choice for carotid artery stenosis, carotid artery stenting (CAS) with use of proximal protection systems (PPS) plays an important role as alternative treatment modality, especially in high risk patients. This study was aimed at the assessment of safety of CAS with use of the PPS and also at identification of risk factors associated with this procedure. Material and methods. This was a post hoc analysis, with 30-day follow-up. We analysed results of treatment of 94 patients who underwent 97 CAS with PPS, 47 such procedures in asymptomatic, and 50 in symptomatic individuals. Results. There were 0 strokes during 30-day fo…

Revacept, an Inhibitor of Platelet Adhesion in Symptomatic Carotid Artery Stenosis: Design and Rationale of a Randomized Phase II Clinical Trial

2020

AbstractPatients with stroke or transient ischemic attacks (TIAs) and internal carotid artery stenosis harbor an increased risk of recurrent stroke especially within 2 weeks after the first event. In addition, the revascularization procedure itself (carotid endarterectomy [CEA] or carotid artery stenting [CAS]) is associated with both clinically apparent and silent brain infarctions, mainly caused by the embolic nature of the ruptured carotid plaque. The glycoprotein VI (GPVI) fusion protein Revacept is a highly specific antithrombotic drug without direct inhibition of systemic platelet function that might reduce periprocedural distal embolization from the vulnerable ruptured plaque located…
