The aim of this study was to
evaluate the Enclose II anastomosis device (Novare Surgical
System, Inc., Cupertino, CA). A retrospective record review
was conducted of all cases which underwent off-pump coronary
artery bypass surgery (OPCAB) at our general hospital
between January 2002 and December 2006. We identified
91 patients (a mean age of 71.0 years, the average number
of distal anastomoses 2.5/patient) underwent OPCAB. The
proximal anastomoses were constructed with the Enclose
II (group E, 40 patients), aorta side-clamp technique
(group S, 17 patients), and aorta no touch (group N, 34
patients). Group E had more grafts than group N (E:N2.7:1.7/patient,
p0.0001), while Group E (3.1/patient) had more distal
anastomoses than group S (2.6/patient, p0.0486) and N
(1.8/patient, p0.0001). There was no difference of graft
patency in each group (early; E:S:N99.1%:97.8%:98.0%,
1-year; E:S:N95.8%:91.3%:95.2%). There was no patient
with sustained permanent neurologic deficits after OPCAB.
The Novare Enclose U proximal anastomotic device appears
to be a safe and effective tool during OPCAB.
