Objective: The transradial approach (TRA) has been widely used
for coronary procedures. The rate of complications such as bleeding,
hematoma and pseudoaneurysm is reduced with TRA. The purpose
of this study is to search the treatment role of anti-aggregants and
low molecular weight heparins (LMWH) in situation of radial
artery occlusion (RAO).
Methods: A total of 239 patients (140 men, 58.6%) were included.
Of the patients 159 (66.5%) were elective, and 80 (33.5%) had
acute coronary syndrome. When RAO was detected, patients were
treated with 2 weeks of LMWH.
Results: In 23 (9.6%) of 239 patients, RAO was observed. From
the 23 patients with RAO, 12 (52.8%) were using anti-aggregants,
and the remaining 11 (47.8%) did not use. In terms of RAO, a
statistically significant difference was observed between antiaggregant
users and non-users (p<0.001). In the group using antiaggregants
and LMWH a statistically significant improvement
was observed in the radial flow compared with the group treated
withLMWH alone (p<0.001).
Conclusion: In the present study, we showed that the addition of
anti-aggregants to anti-coagulants decreased RAO rate, declined the
symptoms of RAO, also potentiated the effects of anti-coagulants
and resulted in better recanalization rate of RAO
