1 Comparative study of retrograde and selective cerebral perfusion with transcranial Doppler 
Yoshihisa Tanoue, MD, Ryuji Tominaga, MD, Yoshie Ochiai, MD, Kouji Fukae, MD, Shigeki Morita, MD, Yoshito Kawachi, MD, Hisataka Yasui, MD  The Annals of Thoracic Surgery  Volume 67, Issue 3, Pages (March 1999) DOI: /S (98)

2 Fig 1 Percent changes in middle cerebral artery blood flow velocities measured by transcranial Doppler technique. The flow velocities could not be measured in 1 patient in the selective cerebral perfusion (SCP) group because there was no temporal ultrasonic window as a result of osteoporosis. Retrograde middle cerebral artery flow velocities during retrograde cerebral perfusion (RCP) could be measured in only 3 patients. Middle cerebral artery flow velocities after RCP were significantly increased compared with those after SCP. Data are shown as the mean ± the standard deviation (SD). (Cooling = at a rectal temperature of 20°C during cooling period; CP = during cerebral perfusion, either RCP or SCP; CPB OFF = 30 minutes after weaning from cardiopulmonary bypass; CPB ON = 5 minutes after start of cardiopulmonary bypass; Pre CPB = before cardiopulmonary bypass; Rewarming = at a rectal temperature of 30°C during rewarming period.)
