We have previously reported the occurrence of microembolic ischemia in the
retina during cardiopulmonary bypass, as revealed by fluorescein
angiography. This method has been extended by digital image analysis to
include quantification of the extent of retinal ischemia and has been
applied to a prospective comparative study of 64 patients undergoing
elective coronary operations with either a bubble or a membrane oxygenator.
Patients with diabetes or clinically evident cerebrovascular disease were
excluded. Bypass procedures were standardized in all cases with pulsatile
flow and a 40 microns arterial line filter (Pall EC Plus). Thirty patients
had bypass with a bubble oxygenator (Harvey H1700) and 34 patients had
bypass with a flat sheet membrane oxygenator (COBE CML). In each case
retinal fluorescein angiograms were obtained preoperatively and 5 minutes
before the end of bypass and were processed with a digital image analyzer
(Context Vision GOP-302). Microembolic perfusion defects were identified by
digital subtraction of preoperative and end-bypass angiograms and their
total area was computed. Results. In the bubble oxygenator group retinal
perfusion defects indicative of microembolism occurred in all 30 (100%)
patients. In contrast, over half the patients in the membrane oxygenator
group had normal retinal perfusion, and the prevalence of perfusion defects
(44%; 70% confidence limits 34% to 54%) was significantly less than in the
bubble group (p less than 0.001). In addition, those patients in the
membrane group had significantly fewer lesions (median 0; 70% confidence
limits 0 to 1) than patients in the bubble group (median 2; 70% confidence
limits 2 to 2; p less than 0.001) and also had significantly smaller total
areas of retinal ischemia (median 0 mm2; 70% confidence limits 0 to 0.16
mm2) than the bubble group (median 0.22 mm2; 70% confidence limits 0.21 to
0.27 mm2; p less than 0.001). There was no relationship between the extent
of retinal ischemia and bypass time, arterial blood gas concentrations,
volume of cardiotomy suction or donor blood returned to the pump, or recent
medication with aspirin. Inferences. Digital image analysis of retinal
fluorescein angiograms may provide a method of quantifying microembolic
ischemia in the central nervous system during cardiopulmonary bypass. Flat
sheet membrane oxygenation appears to provide significantly better
protection against microembolic ischemia than bubble oxygenation.
