Everyone craned their necks like a flock of geese competing to peer through the lead glass, counting how many items were similar to those in cardiovascular interventional surgery and how many were rare and unseen.

Xie Wanying, just like Zhang Wang, seized the precious opportunity to learn diligently.

The surgeon picked up a Y-valve, connected the tubing, one end connecting to saline, preparing to inject heparin for systemic heparinization of the patient, a routine step in many interventional surgeries. Since the tube enters the femoral artery under pressure, not a venous drip, the saline bag needs pressure injection. The nurse used a pressure bag over the saline bag, inflating it with a balloon pump to replace the outdated, labor-intensive, and poorly controlled manual squeezing method. 𝒇𝙧𝙚𝓮𝔀𝓮𝒃𝙣𝓸𝒗𝒆𝒍.𝙘𝒐𝒎

During pressure infusion, the nurse had to keep her eyes fixed to prevent accidents.

Whether it’s traditional open surgery or interventional surgery, examinations must be done before treatment to identify the lesion during surgery. Today’s patient was particularly special. The CT scan report temporarily showed no aneurysm, and the doctors couldn’t confirm the presence or specific location of the tumor before surgery, nor whether there was a vascular lesion within the cranium. As discussed preoperatively with the patient and family, a full cerebral angiography must be performed first to completely map the condition of the head’s blood vessels and see if the relevant lesions can be identified.

Contrasting agent production, various positioning for imaging.

The monitor screen displayed the angiographic images of the brain’s blood vessels.

The most interesting aspect of interventional surgery is this. Different specialized departments can clearly reveal the diverse and wonderful vascular distribution maps of various body organs through angiography, each uniquely remarkable.

As previously mentioned with lung angiography, the lung’s blood vessels resemble a thriving tree with branches on both sides. Cardiac angiography, in contrast, looks like a cluster of small lateral twigs. Brain angiography presents extremely bizarre images, each resembling abstract art; it could be two flowers on bare branches, a tangled chaotic web, or a few isolated branches portraying a sense of loneliness.

The on-site cardiology doctors were utterly silent, completely befuddled, almost unable to tell north from south.

Cross-specialty knowledge is as different as fields separated by mountains. Even though medical students study these in textbooks and witness them during internships, truly mastering a specialty’s comprehensive knowledge is beyond the brief internship period; it requires clinical practice that accumulates over years.

Cardiology doctors can’t extrapolate the brain vascular map from the heart’s coronary system map. They are fundamentally and utterly distinct independent anatomical knowledge points.

The only thing they can now confirm first-hand is that brain vascular mapping is indeed much tougher than heart vascular imaging.

The pinnacle of surgery, the pinnacle of neurosurgery, is not baseless boasting. Brain vascular distribution is too broad, the imaged sections too fragmented. To integrate them can’t solely rely on machines for 3D modeling; it’s only the neurosurgeons’ brains that need to spin frantically first.

Thus, it’s imaginable that being a neurosurgeon requires the best brains among all doctors.

The operating room was silent, the control room somber.

The neurosurgeons’ gazes were like cameras, solemnly inputting the images into their minds for detailed review and calculations.
