Do I need a needle for the mammogram

The operation method of breast ductography was as follows: routine disinfection of the affected nipple, squeezing and pinching the nipple to find the nipple orifice of the discharge, removing the surface secretions of the nipple orifice, slowly inserting 1-1.5 cm into the milk duct with a 412-gauge syringe needle (the tip was smoothen), and slowly injecting 0.5-3 ml of 60% meglumine. One lateral and one axial image should be taken immediately after the needle is pulled out, with no or mild pressure to avoid the contrast agent overflow. The casting condition voltage is slightly higher than that of plain film.

During breast ductography, attention should be paid to the correct selection of the lesion duct orifice to prevent false negative results caused by misinsertion of the normal duct. Be careful not to inject small bubbles into the catheter. If there is a lot of nipple discharge, be sure to drain the overflow before injecting the contrast medium to avoid diluting the contrast medium. Contrast medium should be injected slightly slowly. Breast catheter needle into the catheter, the patient generally will not have a severe pain, after the slow injection of contrast media, the patient may have a mild swelling. If there is obvious distension or even pain, distension suddenly disappears, it may be catheter rupture, contrast agent into the interstitium, so the surgeon should avoid too much too fast increase pressure. If THE BREAST catheter ANGIography, the surgeon found that there is resistance, the patient has severe pain, indicating improper intubation, artificially caused a false path, at this time should immediately stop injection, pull out the needle. You can carefully look for the catheter opening again, and pay attention to the direction of the catheter, and repeat the inspection after half an hour. For those with only mass but no nipple discharge, several more milk ducts can be inserted to improve the positive rate.
