Surgical Aspects of Brain Ischaemia Flowmetry in a Clinical Practice and Experiment

Dissertation summary Surgical aspects of brain ischemia Flowmetry in a clinical practice and experiment MUDr. Jiří Dostál, Dpt. of Neurosurgery, Charles University, Faculty of Medicine Supervising Tutor: doc. MUDr. Vladimír Přibáň, Ph.D., Dpt. of Neurosurgery, Charles University, Faculty of Medicine The aim of this dissertation is to assess the options and benefits of a transit time flow measurement (TTF) in brain ischemia prevention in neurosurgery. Case reports from the Department of Neurosurgery, Charles University, Faculty of Medicine in Pilsen show the use and the limits of TTF. Presented case reports show the need of an individual approach in the case of a complex brain vessel surgery. A group of patients surgically treated for an unruptured middle cerebral artery aneurysm was analysed. Possible restriction of blood flow after the clip placement was quantitatively assessed by TTF in the first subgroup of patients. No quantitative flow measurement was performed in the second subgroup. There was no statistically significant difference between the two groups in terms of ischemia prevention. Some cases may entitle the surgeon to consider TTF use. TTF measurement is an invasive procedure and it demands a careful approach to the vessel and its preparation. The authors suggest to leave the use of the TTF to...

Introduction: The surgical and endovascular results of the treatment of pial AVM provided at our Neurosurgical centre are presented. These results are supported by neuropsychological outcomes of subgroup of treated patients. Going by these results and by an overview of literary data on the efficacy and complications of each therapeutic modality, the optimal algorithm of indications is presented Cohort of patients: The main series comprises 222 patients aged 9 to 87 years treated in the years 1998 - 2013. The surgical group consists of 85 patients, 55 patients received solely endovascular treatment. Thirty-four patients were consulted and referred directly to the Radiosurgical unit. The remaining 48 were recommended to abide by the strategy of "watch and wait". A subgroup of 66 patients, who underwent treatment of AVM was neuro-psychologically tested at least two years after treatment using a battery of tests constructed specifically for this study. A control group consisted of 10 subjects without any neurological disease. Results: In the surgical group, serious complications were 3.5% at a 96.5% therapeutic efficacy. As for AVM treated with purely endovascular methods, serious procedural complications were seen in 5.5% of patients, with efficacy totalling 36.4%. One observed patient suffered...
