Popis: Zadnjih četrdesetak godina ultrazvučna (UZ) dijagnostika nalazi svoje mjesto u gotovo svim medicinskim disciplinama. Udruživanjem CW dopplerske tehnike i B moda ultrazvuka uz dodatak obojenog prikaza intravaskularnog protoka (color flow imaging, CFI) stvorena je moćna pretraga. Arterijske okluzije otkrivaju se mjerenjem brzine vršnog vala pulsa (Peak Systolic Velocity Ratio – PSVR), koji se uspoređuje s brzinom protoka proksimalnog kraja žile koji nema UZ elemenata stenoze. U dijagnostici venske patologije pomoću faze respiracije, kompresibilnosti vena, kontinuiranosti protoka i fenomena augumentacije potvrđujemo patologiju venske cirkulacije s visokom specifičnošću i osjetljivošću. Godišnje se dopplerski u našoj ustanovi pregleda oko 600 bolesnika. Kontrole ranije dijagnosticiranih stanja još uvijek zauzimaju gotovo dvije trećine svih pregleda. Novih žilnih dijagnoza bude godišnje oko 120 ili 25% svih pregleda, uglavnom su to duboke venske tromboze i periferne okluzivne bolesti arterija. Otkriva se mali broj aneurizmi koje su češće u muškaraca te mali broj AV fistula koje su većinom jatrogene. Neočekivane „nevaskularne“ dijagnoze nisu rijetkost; ima ih oko 10%. Korist od utvrđivanja ovih stanja je velika, kako za samoga bolesnika, tako i za odjel gdje se bolesnik liječi.
In the last 40 years ultrasound (US, echosonography) has found its place in almost all medical disciplines. A powerful diagnostic method has been created by joining CW Doppler technique and B mode ultrasound with Colour Flow Imaging (CFI)Arterial occlusion is detected by measuring the Peak Systolic Velocity Ratio (PSVR) which differentiates the flow rate in the proximal and in the stenotic portion of the vessel. In diagnosing venous pathology we use respiratory phase, compressibility of the veins, flow continuity, and augmentation phenomenon with high specificity and sensitivity. In our institution over 600 patients are submitted annually to vascular US examination. Follow-ups of previously diagnosed conditions still occupy nearly two-thirds of them. New vascular diagnoses occur on average in about 120 cases (around 25%). These are mainly deep vein thrombosis and peripheral occlusive arterial disease. A small number of aneurysms which are more common in the male population, and a small number of AV fistulas, usually iatrogenic, have also been found. Unexpected “nonvascular” findings are not so rare, occurring in about 10% of the examinations, with a huge benefit for the patients and for the wards as well.
