ABSTRACT
Vacuum-assisted venous drainage (VAVD) can facilitate venous drainage in single-access minimally invasive cardiac surgery (SAMICS). We retrospectively examined the use of VAVD in SAMICS in our hospital for this report. VAVD has been performed according to a VAVD protocol since 2000. Data from the 110 patients who underwent SAMICS in our institute from January 2000 to June 2002 were reviewed retrospectively. The total negative pressure was maintained at no greater than -90 mmHg. Indications for use of VAVD (protocol) were: insufficient venous return by siphon drainage alone, persistent elevation of the central venous pressure (CVP), and, insufficient venous drainage in the operative field. Of 110 patients, 97 (88.2%) underwent VAVD. The body surface area was significantly smaller in the group that did not require VAVD (the non-VAVD group) than in the group that did (VAVD group) (VAVD group versus non-VAVD group: 1.586 +/- 0.175 versus 1.408 +/- 0.153 m(2), P < 0.001). Other factors such as cardiopulmonary bypass time, aortic cross-clamp time, postoperative maximum lactate dehydrogenase, postoperative maximum creatinine, postoperative maximum blood urea nitrogen were similar in the two groups. VAVD is necessary in SAMICS except for small patients. A VAVD total negative pressure of -90 mmHg did not hinder operative procedures or cause clinical problems.

We report a rare case of a rupture in Kommerell's diverticulum in a 73-year-old woman with Edwards IIIB aberrant left subclavian artery (A-LSA) and right aortic arch. This case was further complicated by an inferior vena cava defect. We performed an emergency operation through a right posterolateral approach. The descending aorta was replaced and the Kommerell's diverticulum was excised, followed by A-LSA reconstruction, performed under deep hypothermia with selective cerebral perfusion. We believe the prognosis was excellent.
