LÆKNABLAÐIÐ 1997; 83 491 meðferð með getnaðarvarnartöflum. Ekki liggja fyrir framskyggnar rannsóknir sem sanna hvort slík rannsókn eigi rétt á sér en að áliti höfunda þessarar greinar ber að skima fyrir stökkbreytingunni ef saga er um segamyndun hjá viðkomandi einstaklingi eða ef ættarsaga er um segamyndun (26). Skimun getur ýmist verið gerð með mælingu á aPC-viðnámi eða arfgerðargreiningu (27). Það er einnig álit höf- unda að fyrirbyggjandi blóðþynning sé æskileg fyrir meiriháttar skurðaðgerðir hjá arfhreinum einstaklingum svo og arfblendnum einstakling- um sem hafa sögu um bláæðasega. Þakkir Vísindasjóður Sjúkrahúss Reykjavíkur fær þakkir fyrir fjárhagslegan stuðning. Starfsfólk Blóðbanka íslands fær einnig þakkir fyrir að- stoð við söfnun sýna. HEIMILDIR 1. Goldhaber SZ.
