Introduction to coronary imaging with 64-slice computed tomography

2005

The aim of this article is to illustrate the main technical improvements in the last generation of 64-row CT scanners and the possible applications in coronary angiography. In particular, we describe the new physical components (X-ray tube-detectors system) and the general scan and reconstruction parameters. We then define the scan protocols for coronary angiography with the new generation of 64-row CT scanners to enable radiologists to perform a CT study on the basis of the diagnostic possibilities.

Virtuālo asistentu izmantošanas iespējas valsts pārvaldē.

2019

Virtuālie asistenti šobrīd ir trends, ko cenšas ieviest un izmantot dažādu industriju pārstāvji, tāpēc arī valsts pārvaldē nepieciešams ieviest virtuālos asistentus, lai uzlabotu darba rezultātus vai atslogotu darbiniekus augstākas pievienotās vērtības uzdevumu veikšanai. Pētījuma mērķis ir izpētīt virtuālo asistentu izmantošanas iespējas valsts pārvaldē, ieguvumus no to ieviešanas un izmantošanas, kā arī izstrādāt priekšlikumus virtuālo asistentu izmantošanai. Pētījuma rezultāti parāda, ka Latvijas valsts pārvalde plāno izveidot vienoto virtuālo asistentu platformu, bet ņemot vērā, ka lietotājiem nav virtuālā asistenta izmantošanas pieredzes, jāveic visas nepieciešamās darbības, lai nodroš…

Farmaceitu fiziskā un garīgā darba slodze aptieku vidē un veselības veicināšanas pasākumi

2021

Farmaceiti darba procesa ietvaros ilgstoši atrodas fiziskā un garīgā noslodzē, kas var būt iemesls diskomfortam un dažādām sāpēm, īpaši muguras muskulatūrā. Apkalpojot klientus tiek intensīvi noslogota redze, pateicoties zāļu izsniegšanas procesam e-veselībā, bet kontakts ar klientiem nereti izraisa psihosociālo risku radītās veselības problēmas. Maģistra darbā ir pētīti ergonomiskie vides riska faktori farmaceitu un asistentu darbā, kā tie ietekmē to fizisko un garīgo slodzi aptiekas vidē; izstrādāti veselības veicināšanas pasākumi slodzes mazināšanai. Darbā iegūtie rezultāti pierāda, ka farmaceiti ikdienas darbā pakļauti ergonomiskiem riskiem, kas tiešā veidā ietekmē farmaceitu fizisko un…

Malignant colorectal obstruction. Palliative endoscopic treatment with self-expanding metallic stents

2005

The Authors report their experience in the palliative management of malignant colorectal obstruction. Between June 2000 and April 2003 sixteen patients (11 men and 5 women, age range 63-82) were found suffering from malignant colorectal obstruction. In these patients it was not possible to perform definitive surgical treatment because of the old age, advanced neoplastic disease and poor health condition, colostomy was the only therapeutic option. Endoscopic self-expanding stents placement was performed as a definitive palliative method to treat colorectal obstructions caused by advanced and unresectable tumours. This procedure was performed under endoscopic and fluoroscopic control and neit…

Endovascular treatment for chronic cerebrospinal venous insufficiency: is the procedure safe?

2010

Objectives The aim of this report is to assess the safety of endovascular treatment for chronic cerebrospinal venous insufficiency (CCSVI). Although balloon angioplasty and stenting seem to be safe procedures, there are currently no data on the treatment of a large group of patients with this vascular pathology. Methods A total of 564 endovascular procedures (balloon angioplasty or, if this procedure failed, stenting) were performed during 344 interventions in 331 CCSVI patients with associated multiple sclerosis. Results Balloon angioplasty alone was performed in 192 cases (55.8%), whereas the stenting of at least one vein was required in the remaining 152 cases (44.2%). There were no majo…

Insights on a Giant Aneurysm Treated Endovascularly

2015

Background  Endovascular treatment with stent-assisted Guglielmi detachable coils is an accepted method for treating intracranial giant aneurysms that otherwise would require more invasive or destructive treatment or could not be treated at all. Nevertheless, there is a paucity of information concerning inner postcoiling aneurysmal changes in human subjects over the long term. We report a postmortem analysis of a patient with a giant aneurysm at the vertebrobasilar junction (VBJ) who was treated endovascularly and studied pathologically 24 months after treatment. Materials and Method  The head was removed at autopsy and prefixed in a 10% neutral buffered formalin solution. The brain was gen…

Czas inflacji balonu podczas angioplastyki obwodowej — jak to robimy?

2018

Wstęp: Zabiegi wewnątrznaczyniowe u pacjentów z miażdżycą tętnic poniżej więzadła pachwinowego są najczęstszymi procedurami wewnątrznaczyniowymi w chirurgii naczyniowej. Angioplastyka balonowa (PTA) jest nieodłącznym elementem prawie każdego zabiegu, bez względu na to czy decydujemy się na implantację stentu. Nie ma wytycznych ani zaleceń wskazujących jak długo należy trzymać napompowany balon do angioplastyki w obrębie zmiany miażdżycowej. Decyzja ta należy do operatora i jest oparta na jego/jej opinii i doświadczeniu. Czas inflacji balonu i jego wpływ na wynik angioplastyki do tej pory nie był przedmiotem randomizowanych badań klinicznych. Celem niniejszego badania ankietowego było określ…

Endovascular treatment of spontaneous isolated abdominal aortic dissection

2016

Isolated abdominal aortic dissection is a rare clinical disease representing only 1.3% of all dissections. There are a few case series reported in the literature. The causes of this pathology can be spontaneous, iatrogenic, or traumatic. Most patients are asymptomatic and symptoms are usually abdominal or back pain, while claudication and lower limb ischemia are rare. Surgical and endovascular treatment are two valid options with acceptable results. We herein describe nine cases of symptomatic spontaneous isolated abdominal aortic dissection, out of which four successfully were treated with an endovascular approach between July 2003 and July 2013. All patients were men, smokers, symptomati…

Classification of coronary artery bifurcation lesions and treatments: time for a consensus

2008

Background: Percutaneous coronary intervention (PCI) of coronary bifurcation lesions remains a subject of debate. Many studies have been published in this setting. They are often small scale and display methodological flaws and other shortcomings such as inaccurate designation of lesions, heterogeneity, and inadequate description of techniques implemented. Methods: The aim is to propose a consensus established by the European Bifurcation Club (EBC), on the definition and classification of bifurcation lesions and treatments implemented with the purpose of allowing comparisons between techniques in various anatomical and clinical settings. Results: A bifurcation lesion is a coronary artery na…
