Part 3: The Zurich Consultation
The next twenty-four hours crawled by like a slow-moving tide, each minute measured by the rhythmic hiss of the ventilator and the green blips of the bedside monitors. Dr. Bennett had ordered continuous hemodynamic monitoring for both girls, turning their space into a command center filled with blinking lights, IV poles, and a rotating crew of critical-care nurses.
Rachel refused to leave the room. She ate whatever the nursing staff brought her—mostly cold sandwiches and lukewarm coffee—without tasting a single bite. Her eyes remained fixed on the monitors, learning to read the subtle shifts in waveform that indicated Emma’s heart was straining a fraction more than it had an hour before.
At midnight, a secure video link was established on the wall-mounted console in the adjacent consultation room. Dr. Julian Vance appeared on the screen, looking crisp and alert despite the late hour in Switzerland. His hair was silver at the temples, and his eyes possessed the piercing, analytical clarity of a surgeon who spent his life making decisions in fractions of a second.
Dr. Bennett, Dr. Reed, and Rachel sat around the conference table as the Swiss specialist reviewed the high-resolution 3D models of the twins' shared anatomy.
“The configuration is remarkably complex,” Dr. Vance said, his voice coming through the speakers with a clear, clipped British accent. “The shared liver tissue is relatively straightforward; we’ve dealt with hepatic bridges of this volume before. But the mesenteric artery anomaly—that is the critical variable.”
“Can we ligate it on Lily’s side and rely on collateral flow?” Dr. Bennett asked, leaning forward with her elbows on the table.
Dr. Vance shook his head instantly. “Absolutely not, Claire. Look at Lily’s baseline perfusion index. Her microvascular resistance is already elevated due to chronic low-grade hypoxia. If you ligate that vessel without an immediate, patent bypass, her bowel will undergo necrosis within four hours. You’ll save Emma from cardiac failure only to subject Lily to short-gut syndrome and systemic sepsis.”
Rachel felt a cold shiver run down her spine. “Then what do we do? Is there a way to split the vessel?”
Dr. Vance turned his gaze toward the camera, locking eyes with Rachel across thousands of miles of fiber-optic cable. “Mrs. Carter, the artery is roughly one point five millimeters in diameter. Splitting it longitudinally is mechanically impossible without destroying the endothelial lining on both sides. However, there is a third option.”
The room went completely silent. Even the hum of the cooling fan on the console seemed to vanish.
“Go on, Julian,” Dr. Bennett urged.
“We perform a staged separation,” Dr. Vance explained, bringing up a simulated animation on his end that projected onto their screen. “We don’t cut the vessel immediately. Instead, forty-eight hours prior to the main separation surgery, we place an adjustable micro-vascular clamp—a constrictor—around the trunk of the shared artery on Emma’s side. Over the course of those forty-eight hours, we gradually reduce the flow to Emma, forcing Lily’s own angiogenic pathways to develop collateral vessels of her own.”
Dr. Reed frowned, leaning back in his chair. “Angiogenesis takes weeks, Julian, not forty-eight hours. Lily’s body won’t adapt fast enough.”
“Normally, no,” Dr. Vance conceded. “Unless we introduce vascular endothelial growth factor directly into the mesenteric bed during the initial clamping phase. We tested this protocol on an experimental model in Zurich last year. It accelerates collateral vessel formation by nearly three hundred percent.”
Dr. Bennett stared at the screen, her brow furrowed in intense concentration as she calculated the physiological risks. “And Emma’s heart? While we’re waiting for Lily’s circulation to adapt, Emma’s heart still has to bear the burden of supporting her sister.”
“True,” Dr. Vance said. “Which is why we place Emma on a temporary, low-flow extracorporeal assist device during those exact forty-eight hours. We take the workload off her right ventricle entirely, allowing her heart muscle to rest, recover, and prepare for the surgical division.”
Rachel looked back and forth between Dr. Bennett, Dr. Reed, and the image of Dr. Vance on the screen. It sounded like science fiction—a complex dance of clamps, growth factors, and mechanical bypasses designed to trick biology into rewriting its own rules.
“What are the risks?” Rachel asked, her voice cutting through the medical jargon like a sharp blade. “If we do this staged approach with the clamp and the bypass... what happens if it fails?”
Dr. Vance did not look away. He answered with the unvarnished brutal honesty that parents in the ICU needed, no matter how much it hurt.
“If the clamp restricts Emma’s flow too quickly, Lily’s bowel still dies, and we face an emergency resection on the operating table,” Dr. Vance said calmly. “If the assist device causes micro-emboli in Emma’s circulation, she could suffer a neurological event. The risks are substantial, Mrs. Carter. Approximately thirty-five percent mortality for Lily, and fifteen percent morbidity for Emma.”
Rachel closed her eyes. Thirty-five percent. Fifteen percent. Numbers that represented life and death, health and permanent disability, wrapped up in medical percentages calculated by computers and human hands.
She thought of her daughters sleeping just down the hall. Emma, with her fierce, protective love and her tired little heart. Lily, with her quiet strength, fighting for every breath in a body that was only half her own.
“When can you be here, Dr. Vance?” Rachel asked quietly.
Dr. Vance blinked in surprise, then offered a slight, respectful nod. “I have a private charter out of Zurich in two hours. I’ll touch down at your local airfield tomorrow morning at 06:00 local time. Have the surgical suite prepped and ready.”
The video feed clicked off, leaving the screen glowing with a blank blue logo.
Dr. Bennett stood up, pushing her chair back with a sharp scrape against the floor. “Well, you heard him. We have less than twenty-four hours to prepare the pediatric ICU for a combined micro-vascular assist and staged clamping protocol we’ve never performed outside of a simulation lab.”

She looked down at Rachel, her expression softening just a fraction. “Are you sure about this, Mrs. Carter? Once we start the assist pump on Emma, there’s no turning back.”
“I’m sure,” Rachel said, standing up to face the surgeon head-on. “My daughters didn’t fight this hard for ten months just to give up now. Save them both, Dr. Bennett. Do whatever it takes.”
