Objective to compare two compression times of the radial artery after coronary
angiography with customized compressive dressing regarding the occurrence of
hemostasis and vascular complications.Method a randomized clinical study was carried out in patients undergoing elective
transradial coronary angiography in two study groups: (G30), whose
compressive dressing was maintained for 30 minutes, and (G60), whose
compressive dressing was maintained for 60 minutes, both until the first
evaluation of hemostasis. Variables related to patients, procedure,
occurrence of hemostasis, and vascular complications were analyzed. Patency
of the radial artery was assessed with Doppler vascular ultrasonography,
immediately after removing the compressive dressing and 30 days after the
procedure.Results the sample consisted of 152 patients in G30 and 151 in G60. Hemostasis was
evidenced in the first evaluation in 76.3% of G30 patients and 84.2% of G60
patients (p = 0.063). There were 91 immediate complications, being 53
hematomas and 38 occlusions of the radial artery. We identified 18 late
occlusions, 7 (5.5%) in G30 and 11 (8.2%) in G60.Conclusion the different compression times of the radial artery after coronary
angiography did not significantly influence the occurrence of hemostasis and
vascular complications. Brazilian Registry of Clinical Trials (Rebec): .
