Clinical Anatomy of the Arteries of the Trumb and the First Web Space
Miletín, Jakub ; Kachlík, David (advisor) ; Stingl, Josef (referee) ; Měšťák, Ondřej (referee)
The thumb is absolutely essential for the flawless function of the hand, and the loss of the structure or function of the thumb almost always means a partial or total invalidation of the patient. Thus, salvage and reconstruction of the thumb is one of the foremost topics in hand surgery. Modern conservation and reconstructive procedures of hand surgery require a completely new insight into the knowledge of vascular anatomy. In order for the information to be comprehensible and well communicated, it is necessary to have a sufficiently detailed, clear and, above all, uniform nomenclature. When taking a closer look at the anatomy of the vessels of the hand, it turns out that authors often do not use generally accepted terms or do not agree on the interpretation of the correctly used ones. The above stated facts led us to the conclusion that, although the anatomy of the hand arteries seems to have been well studied and described in the past, there is still considerable room for sorting out the previously described data, revising the nomenclature, completing the missing detailed description of some anatomical variations and assessing the significance and usefulness of individual structures in relation to trauma and reconstructive hand surgery. This work describes in detail the systemic and topographical...

Treatment for Brain Arteriovenous Malformations
Bradáč, Ondřej ; Beneš, Vladimír (advisor) ; Haninec, Pavel (referee) ; Vaverka, Miroslav (referee)
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...

Intracranial Aneurysms - Treatment Options and Natural Course. Safety and Efficacy of Treatment Strategies for Posterior Inferior Cerebellar Artery Aneurysms.
Petr, Ondřej ; Beneš, Vladimír (advisor) ; Haninec, Pavel (referee) ; Přibáň, Vladimír (referee)
BACKGROUND: Posterior inferior cerebellar artery (PICA) aneurysms are an uncommon, heterogeneous group of aneurysms with poorer neurological outcomes compared to other intracranial aneurysms. At first, as part A, we conducted a systematic review of the literature to evaluate the safety and efficacy of treatment strategies for PICA-aneurysms. Subsequently, as part B, we performed a multicenter retrospective study to analyze the outcome in a large series of patients treated with contemporary microsurgical and endovascular techniques. METHODS: For the meta-analysis, a systematic search of Medline, EMBASE, Scopus and Web of Science was done for studies published through November 2015. We included studies that described treatment of PICA-aneurysms with ≥10 patients. Random-effects meta-analysis was used to pool the following outcomes: complete occlusion, technical success, periprocedural morbidity/mortality, stroke rates, aneurysm recurrence/rebleed, CN-palsies rates, and long-term neurological morbidity/mortality. As the second part, aiming to report the current trends and results in treatment strategies for PICA-aneurysms, records of 94 patients treated for PICA-aneurysms between 2000 and 2015 at 3 large referral neurovascular centers were retrospectively reviewed. RESULTS: In the meta-analysis, we...
