ar þegar árangur er ræddur. Meginniðurstaða Phill-
ips og félaga er sú að' hættur slíkra aðgerða séu ekki
meiri en áformaöra kransæðaaðgerða sé vissum skil-
yrðum fylgt (aðgerðadauði 1,3% síðlát 2,7%). De-
Wood og félagar komast að svipaðri niðurstöðu
varðandi áhættuna. Jafnframt telja þeir sig hafa
sýnt fram á að sjúklingum sem eru skornir reiði bet-
ur af en hinum, hvort sem litiö er til styttri eða
lengri tíma (5,8% vs 11,5% og 11,7% vs 20,5%).
Niðurstöður þeirra hafa sætt nokkurri gagnrýni en
þrátt fyrir það eru sérfræðingar sammála um að
þessar niðurstöður séu mjög athyglisverðar og frek-
ari rannsóknir nauðsynlegar.
Höfundur þakkar Þórði Harðarsyni yfirlœkni fyrir
lestur handrits og vinsamlegar ábendingar.
