Thoracic aorta wall pathology: diagnosis, stentgraft placement, indications, strategy and procedure technique, clinical results Aim. Our single-center study was designed to assess management of thoracic aorta using a stent graft in individual types of pathology. While focused on the technical success rates and efficacy of management, the study also sought to document the incidence of intra- procedural complications and to assess the rate of sac growth and endoleak incidence. Method. A total of 86 patients with thoracic aorta disease were treated using a stent graft over a period of 12 years. They were 24 women and 62 men with a mean age 58.5 years. Late CT follow-up was performed in 75 patients, 31 (36%) were lost to follow-up, most (25) patients died. The most frequent reason (50%) for treatment included size of the aneurysmal sac, with progressive sac growth accounting for 19%. Results. Complications were rare, with most serious ones including 6 cases (7%) of hemorrhage, 3 fatal cases, with the other cases (peripheral bleeding) managed by a surgeon. Primarily intractable endoleak documented by DSA was observed in 9 treated patients (10%). The most frequent CT-documented endoleak was Type I endoleak diagnosed in 18 treated patients (20%). Spontaneous endoleak regression was demonstrated in 6...

Patency of dialysis fistulas in patients undergoing vascular interventional procedures.
Kaván, Jan ; Lambert, Lukáš (advisor) ; Chochola, Miroslav (referee) ; Beran, Jan (referee)
Purpose. The primary objective was to compare primary and secondary patency, number of percutaneous transluminal angioplasty (PTA) interventions and cost-effectiveness among PTA, deployment of a stent, or a stent graft in the treatment of failing arteriovenous dialysis grafts. The secondary objective was to compare the residual diameter at the site of dialysis shunt stenosis using sonography and digital subtraction angiography (DSA). Methods. Sixty patients were randomly assigned to either PTA, placement of a stent or stent graft. Follow-up angiography was scheduled at 3, 6, and 12 months or when requested by the physician. Residual diameter of a dialysis shunt stenosis was measured in 20 patients with significant stenosis by ultrasonography and on an angiogram from DSA. Results. During a median follow-up of 22.4 months patients with PTA, stent, or stent graft required 3.1±1.7, 2.5±1.7, or 1.7±2.1 (P=0.031) secondary PTA interventions. The primary patency rates were 0%, 18%, and 65% at 12 months and 0%, 18%, and 37% at 24 months in the PTA, stent, and stent graft group respectively (P<0.0001). The cost of the procedures was €7,900±€3,300 in PTA group, €8,500±€4,500 in stent group, and €7,500±€6,200 in stent graft group (P=0.45). The mean residual diameter measured by ultrasonography and DSA was...

Diagnosis of deep vein thrombosis with ultrasonography
Pinka, Jiří ; Karetová, Debora (advisor) ; Chochola, Miroslav (referee)
This thesis is retrospective study group of patients who visited the internal medicine clinic at hospital in Vyškov during the year 2010 with a suspected thrombotic closure of limb veins. As a source of information were used outpatient and inpatient discharge and sonographic reports. A total of 1000 patients were examined, of whom were 379 men and 621 women. Thanks to graphical process groups were formed, which included examined patients with common causes of thrombosis, clinical symptoms, sonographic findings, and lateral extent of disability thrombosis. These groups were subjected to statistical evaluation and comparison to identify traits and patterns of side differences in the limb affection, the clinical problems related to the extent of thrombotic disability, the relationship of embolization risk of thrombotic events to the extent of thrombotic disability. There was available sonographic machine Toshiba Nemio SSA-550A year of manufacture 2002 with a linear probe for vascular investigations and it was equipped with color Doppler. The source of information was anamnestic data obtained during an outpatient consultation or hospitalization. In the in-hospital reports were objective clinical examinations, numerous laboratory data characterizing the extent of the inflammatory response, affected...
