Lắp "cửa sổ" để chữa trị não bộ bị chấn thương?
các bác sĩ giải phẫu thần kinh đang thử nghiệm lắp một bộ phận giả, cho phép họ nhìn vào đầu bệnh nhân bằng sóng siêu âm.
Tucker Marr’s life changed forever last October.
He was on his way to a wedding reception when he fell down a steep flight of metal stairs, banging the right side of his head so hard he went into a coma (hôn mê).
He’d fractured (làm vỡ) his skull, and a large blood clot (cục máu đông) formed on the left side of his head. Surgeons (bác sĩ phẫu thuật) had to remove a large chunk (mảnh) of his skull to relieve pressure on his brain and to remove the clot.
“Getting a piece of my skull taken out was crazy to me,” Mr. Marr said. “I almost felt like I’d lost a piece of me.”
But what seemed even crazier to him was the way that piece was restored (khôi phục).
Mr. Marr, a 27-year-old analyst at Deloitte, became part of a new development in neurosurgery (giải phẫu thần kinh). Instead of remaining without a piece of skull or getting the old bone put back, a procedure (thủ thuật) that is expensive and has a high rate of infection (nhiễm khuẩn), he got a prosthetic piece of skull made with a 3-D printer. But it is not the typical prosthesis used in such cases. His prosthesis (bộ phận giả), which is covered by his skin, is embedded (gắn vào) with an acrylic window that would let doctors peer into his brain with ultrasound (sóng siêu âm).
...Advocates of the technique say that if a patient with such a window has a headache or a seizure or needs a scan to see if a tumor (khối u) is growing, a doctor can slide an ultrasound probe on the patient’s head and look at the brain in the office. That way a patient can avoid costly, time-consuming and onerous CT scans or M.R.I.s. Instead of waiting for a radiologist (bác sĩ X quang) to read the scan, a patient and a doctor can know right away what the patient’s brain looks like.
