Flow void Sinus

Als Sinusvenenthrombose kann die Auslöschung des venösen Sinus bei der

Sinugraphie mißgedeutet werden, wenn ein sehr niedriger Fluß vorliegt

(LOW flow Sinus). Verifizierung über Kontrast-Sinugraphie oder

3mm T1 Kontrastaufnahmen dann nur möglich.

Daher:

Interpretation einer Phasenkontrast oder flowsensitiven Sinugraphie

nur mit Kontrastsinugraphie zur Diagnose einer Sinusthrombose!

    He summarized the main highlights of the new guidelines as follows:

    Diagnostic Recommendations
    » The diagnostic recommendations are based on the impact of diagnostic procedures on patient outcome and not on process indicators.
    » For the diagnosis of CVT, computed tomographic venography, magnetic resonance venography, or intra-arterial venography can be used because these techniques have similar accuracies.
    » Prothrombotic and cancer screening are not recommended as a routine.

    Therapeutic Recommendations
    » All patients with acute CVT should be anticoagulated parentally, preferably with low-molecular-weight heparin (LMWH).
    » Patients with large hemisphere lesions with impending herniation should be offered decompressive surgery.
    » Seizure prophylaxis with anticonvulsants is indicated in patients who experience an acute symptomatic seizure and have a venous infarct or hemorrhage.
    » Non–vitamin K anticoagulants (novel oral anticoagulants) are not recommended, particularly in the acute phase, because of the limited experience and unknown safety.
    » No recommendations could be made regarding acute endovascular treatment because of the very low quality of available evidence, pending the publication of the final results of the TO-ACT trial, which was prematurely terminated for futility this year.
    » Pregnancy is not contraindicated after CVT, and subcutaneous LMWH is suggested during pregnancy to prevent recurrent venous thrombotic events.
