Table 1:

Complication rates and a comparison of hematoma rates between Angio-Seal and manual compression at different ACT levels^{^a}

↵a Complication rate (hematoma >10 cm) 0.96 (1.11)% for Angio-Seal and 4.28 (2.98)% for manual compression. Patient numbers and complication rates in parentheses.
↵b Four patients with bilateral arteriotomies closed by Angio-Seal and manual compression, respectively.
↵c One patient with bilateral Angio-Seal and bilateral hematomas simultaneously.
