Chapter 11 - SCRUBBING IN
With cardiopulmonary bypass fully established and the heart arrested via cold cardioplegia infusion,
the field became eerily still.
The rhythmic monitors hummed a steady electronic tune,
replacing the natural beat of Richard’s heart with mechanical persistence.
I inspected the arrested aorta closely under high-magnification surgical loupes,
marveling at the extent of the intimal tear.
The inner layer of the vessel had peeled away like wet wallpaper,
creating a false lumen that tracked all the way down to the renal arteries.
This was not just a standard dissection; it was an extensive architectural collapse of the body’s primary circulatory highway.
I called for the aortic cross-clamp,
positioning it carefully across the distal ascending aorta to isolate the damaged segment.
Brenda handed me the precision tissue forceps and a fine surgical blade to open the diseased vessel wall.
I made a clean,
longitudinal incision along the anterior surface of the ascending aorta,
releasing a rush of old,
dark clots.
The true and false lumens lay exposed before us,
revealing the catastrophic extent of the structural failure.
I instructed the perfusionist to lower the systemic core temperature to eighteen degrees Celsius for deep hypothermic circulatory arrest.
Lowering the body temperature protected the brain and vital organs from ischemic injury while the cerebral circulation was temporarily halted.
The digital thermometer on the anesthesia console ticked downward steadily: thirty degrees,
twenty-five degrees,
twenty degrees,
eighteen degrees.
The room grew noticeably cooler as the specialized cooling blankets circulated ice-cold fluid beneath the patient.
I checked Richard’s electroencephalogram trace on the brain monitor,
watching the brain wave activity flatten into a safe,
protective coma.
When the core temperature hit the target threshold,
I gave the crisp command to halt the systemic pump completely.
Total circulatory arrest initiated.
The operating room fell into an absolute,
breathless silence,
broken only by the quiet hum of our own breathing.
We now had a strict window of forty-five minutes to excise the torn aortic arch,
sew in a synthetic woven graft,
and resume cerebral perfusion.
Every second counted like grains of sand slipping through an hourglass.
I grasped the torn edges of the aortic root with delicate bulldog clamps,
preparing to excise the compromised tissue.
My hands were rock-steady,
moving with the practiced grace of a concert pianist playing a complex sonata.
The surgical assistant held the suction catheter steady,
keeping the field clear of any residual blood pooling.
I excised the damaged ascending aorta with clean,
precise cuts,
discarding the diseased tissue into the stainless steel basin.
Now came the centerpiece of the procedure: sewing the multi-branched Dacron graft into place under microscopic precision.

I took up the fine polypropylene suture,
aligning the first stitch through the fragile remnant of the aortic annulus with absolute perfection.
