Objective: Cerebrovascular atherosclerosis is known to play a crucial role in perioperative stroke in coronary arterial bypass grafting (CABG). This study is to identify the degree of severity of cerebrovascular lesions for which patients can still undergo CABG with an acceptably low risk in current techniques. Methods: Cerebrovascular atherosclerosis was evaluated and graded for 200 consecutive patients prior to CABG. Grading was initially based on the level of stenosis in carotid, vertebral, and cerebral arteries: grade-0: normal or mild stenosis in cerebral arteries or stenosis <50% in other arteries;grade-1: moderate in cerebral arteries or 50% - 69% in others;grade-2: severe in cerebral arteries or 70% - 89% in others;grade-3: occlusion in cerebral arteries or 90% - 100% in others. The grading was finally adjusted to a risk of regional ischemia by considering symptoms, number of lesions, and brain perfusion in scintigram. Therefore, some patients were up-graded. Off-pump CABG was scheduled for all patients. The lowest systolic arterial pressure during surgery was differently controlled in each grade: grade-0: ≥70 mmHg;grade-1: ≥80 mmHg;grade-2: ≥80 mmHg with intra-aortic balloon pump (IABP);grade-3: ≥90 mmHg with IABP;grade-4: ≥90 mmHg with IABP and administration of thyamiral. Results: Grade-1 and -2 included 38 and 29 patients respectively. Grade-3 initially included 36 patients and 14 of them were up-graded to grade-4 (extremely high risk patients). Stroke was seen in one patient (0.5%), for whom mild speaking disturbance occurred on the fifth day from CABG. Conclusion: Patients with severe cerebrovascular atherosclerosis can undergo CABG with a low risk of stroke. Intraoperative management of blood pressure may be critical for stroke prevention in CABG.

A high angular resolution near-infrared image that shows the intensity of polarization for the GG Tau A binary system was obtained with the Subaru Telescope. The image shows a circumbinary disk scattering the light from the central binary. The azimuthal profile of the intensity of polarization for the circumbinary disk is roughly reproduced by a simple disk model with the Henyey-Greenstein phase function and the Rayleigh function, indicating there are small dust grains at the surface of the disk. Combined with a previous observation of the circumbinary disk, our image indicates that the gap structure in the circumbinary disk orbits counterclockwise, but material in the disk orbits clockwise. We propose that there is a shadow caused by material located between the central binary and the circumbinary disk. The separations and position angles of the stellar components of the binary in the past 20 yr are consistent with the binary orbit with a = 33.4 AU and e = 0.34.
