The unexpected incident left Liang Xiong absolutely stunned!
Because he discovered that the 4F caliber catheter simply could not penetrate and reach the tethered area.
It was definitely not an issue with the diameter of the brachial artery!
It was because the angle became tricky after the vascular malformation, making it very difficult to pass through this area along the vessel!
But...
With so many years of experience, Liang Xiong shouldn't have misjudged, right?
How could such a situation arise?
Liang Xiong couldn't help but frown and murmured, "This angle should be passable!"
Beside him, Zhao Nan couldn't help but say, "We couldn't get through at this place back then either."
"I have a feeling... that it's a lack of catheter compliance, which makes me feel resistance when pushing the catheter, it should be able to go through according to blood flow!"
Upon hearing this, Liang Xiong was momentarily stunned.
