Abstract:

Introduction: a case report of successful treatment of an extremely rare pathology (0,27-0,34%) - acute occlusion of both internal carotid arteries (ICA) is presented.

Aim: was to show possibilities of endovascular surgery in the diagnosis and treatment of acute ischemic stroke (AIS) in patients with bilateral acute ICA occlusion.

Materials and methods: a 38-year-old patient was hospitalized by ambulance with the diagnosis of AIS. Multispiral computed tomography (MSCT) revealed left ICA occlusion in the C2-C5 segment. Selective angiography of ICA was performed: right ICA - non-occlusive thrombosis C2-C3 segments; left ICA - thrombotic occlusion in C1 segment.

Results: thrombaspiration was performed from the left ICA and right ICA; full recovery of antegrade cerebral blood flow was achieved in both ICA, according to the modified treatment in cerebral infarction score (mTICI) - 3. Patient was discharged after 28 days. At the time of discharge, the modified Rankin Scale (mRS) score was 3. 6 months after discharge mRS was 1.

Conclusions: Selective angiography of both ICA in a patient with AIS enabled to detect right ICA thrombosis not detected by MCT, which in its turn changed the treatment tactics of the patient. Aspiration thromebctomy from both internal carotid arteries allowed to achiev full recovery of antergrade cerebral blood flow of both internal carotid arteries.

Abstract:

In this paper the use of spiral computed tomography (SCT) in dental implantation is discussed. It is shown that scanning itself and, what is even more important, post-processing of the images should be planned individually for each patient. SCT is declared to be a substantial part of the diagnostic strategy in patients with upper and lower dental arches defects, and with complete adentia. It is also crucial in assessment of long-term results of sinus lift procedure, and for detection of immediate and remote dental implant complications.

Abstract:

The article provides a case report of the patient with mediastinitis. This case report shows the importance of multispiral computed tomography in the diagnostics of tumors of this localization, demonstrates the need of proper preparation of patient for examination and use of CT with intravenous contrast enhancement, multiplanar reconstruction images to obtain information about the nature of blood flow, determining the structure of esophagus walls and the ratio of detected changes with surrounding organs and vascular structures, which is particularly important for treatment planning.
