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.
