Objective: The ain of this prospective study is to define the clinical significance of diagnosis partial or complete thrombosis of Internal jugular vein (IJV) after insertion of a central venous catheter (CVC) in patients in intensive care unit (ICU).

Materials and Methods: Central venous catheter in IJV is implanted to 233 patients for the period 03.2013 to 05.2013. From all the patients 135 are men, 98 are women, mean age 60,6 years. The IJV is evaluated with Color-coded Duplex Ultrasound (CDU), before insertion of the CVC and at the 7th post procedure day, for the existence of partial or complete thrombosis. Some of the patients with trombosis were symptomatic of thet, other – were asymptomatic. Degree of thrombosis was: incomplete small (less than 50% of the lumen); incomplete high (more than 50% of the lumen) and complete thrombosis. While staying in ICU were used to prophylaxis thrombosis low-molecular-weight heparin and antibiotics.

Stroke is an important complication of sickle cell disease. Approximately twenty-four percent of patients have a stroke by the age of 45 years. Blood transfusions decrease stroke risk in patients deemed high risk by transcranial Doppler (TCD) by evidence of elevated intracranial internal carotid or middle cerebral artery velocity. A follow-up of neurologically symptomatic and asymptomatic sickle cell patients increased other factors were significant in the identification of patients at risk that could include: velocity in the ophthalmic artery > that of the ipsilateral MCA, maximum velocity in the posterior cerebral (PCA), vertebral, or basilar arteries > maximum velocity in the MCA, turbulence, PCA visualized without the MCA.
