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).

Possible Adverse Effects of Hyperventilation on rCBF during the Acute Phase of Total Proximal Occlusion of a Main Cerebral Artery

1969

Recent studies seem to favor a beneficial effect of hyperventilation (HV) in cases of cerebrovascular occlusion [1, 4] and brain trauma [2, 5]. On the other hand, it seems that, at least under certain circumstances, HV may exert an adverse effect upon cerebral blood flow and metabolism [3]. Since this question is not settled yet, it seems worthwhile to report briefly the present case of reversible total occlusion of the middle cerebral artery closely followed by successive rCBF studies (133Xe-gamma-clearance method), in which, during the acute phase, HV caused a latent ischemia to become manifest.

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.

Neuronal immunoreactivity for mannose-binding lectin after venous occlusion-induced focal cerebral ischemia in rats

2012

Abstract A recent research reveals that complement activation exacerbates cerebral infarction. However, involvement of the lectin pathway, (the third complement activation pathway) in cerebral ischemia is not well studied. In this study, we investigated the appearance of mannose-binding lectin (MBL) in ischemic brain tissue. Male Wistar rats ( n  = 25) were divided into three groups: untreated control, sham, and vein occlusion (VO). Rats in the VO group had two adjacent photochemically occluded cortical veins. Regional cerebral blood flow (rCBF) was measured in the sham and VO groups. Rats were perfusion-fixed at 72 h in the sham group and at 3, 24, and 72 h after inducing ischemia in the V…

Pathway CH-1 Study: Sphenopalatine Ganglion (SPG) Stimulation for Acute Treatment of Chronic Cluster Headache (CCH) - Initial Experience (S36.002)

2012

Objective: We aimed to investigate the safety and efficacy of SPG stimulation for the acute treatment of CCH. Background The pain and autonomic symptoms of cluster headache result from activation of the trigeminal parasympathetic reflex, mediated through the SPG. Design/Methods: A multi-center, dose range finding, multiple headache attack (HA), acute treatment study with random insertion of placebo has been initiated. All subjects meet the ICHD-II criteria for CCH with a minimum of 4 HAs/week. Subjects are implanted with a miniaturized neurostimulator which, along with a controller, provides SPG stimulation. Prior to the randomized period, stimulation parameters are adjusted in a titration …

EP626 Lymph vascular space invasion, an independent risk factor of sentinel node mapping failure in endometrial cancer, the sentifail study: a multic…

2019

Introduction/Background Sentinel lymph node (SLN) mapping has become the gold standard for surgical staging of early stage endometrial cancer. Side-specific systematic lymphadenectomy is suggested if SLN mapping failed. The objective of this study is to identify clinical and pathological factors associated with failed mapping. Methodology We prospectively evaluated a consecutive series of early stage endometrial cancer patients submitted to SLN mapping with indocyanine green (ICG) near-infrared compatible surgical platforms in two oncological referral centers from January 2018 to January 2019. Indocyanine green was injected intracervical. Bilateral mapping and failed bilateral SLN mapping g…

Koronare Bypassdiagnostik mit CT und MRT - eine Bestandsaufnahme

2004

The limited lifetime and the correlation between graft occlusion and recurring symptoms underline the need for repeated imaging of coronary artery bypass grafts. CT and MRI allow for non-invasive imaging of coronary bypasses with high accuracies concerning the patency of these vessels. Multidetector CT seems to be the CT technique of choice, especially after the introduction of 16 slice CT scanners for morphologic assessment of coronary artery bypass grafts. Compared with MRI, CT is a robust technique for assessment of cardiac anastomoses, native coronary arteries, and for the detection of graft stenoses. MRI, however, is able to deliver functional information about the grafts and the recip…
