No abnormalities were detected on the previous ultrasound US examination at week 13 of pregnancy. She had normal results on the triple test. She is human immunodeficiency virus HIV, hepatitis B virus HBV, and hepatitis C virus HCV-negative. Her blood type is IIIB Rh, and her partner has blood type I0 Rh-. She and her husband are both of Sardinian descent, do not consume alcohol, and do not smoke. Her cousin had a child who died soon after the birth, but she doesnt know the reason. She does not report a history of any genetic conditions in her family, although notes that her grandfather was always yellowish-pale, fatigued easily, and had problems with his gallbladder. Below are her and her partners complete blood count and electrophoresis results.Complete blood count Patient Her husbandErythrocytes 3.3 millionmm3 4.2 millionmm3Hb 11.9 gdL 13.3 gdLMCV 71 fL 77 fLReticulocyte count 0.005 0.008Leukocyte count 7,500mm3 6,300mm3Platelet count 190,000mm3 256,000mm3ElectrophoresisHbA1 95 98HbA2 3 2HbS 0 0HbH 2 0The patient undergoes ultrasound examination which reveals ascites, liver enlargement, and pleural effusion in the fetus. Further evaluation with Doppler ultrasound shows elevated peak systolic velocity of the fetal middle cerebral artery. Which of the following procedures can be performed for both diagnostic and therapeutic purposes in this case?? A: Fetoscopy, B: Amniocentesis, C: Chorionic villus sampling, D: Cordocentesis, E: Percutaneous fetal thoracentesis,  <response>: This is a question about a pregnant woman who is presenting with a fetus that has ascites, liver enlargement, pleural effusion, and elevated middle cerebral artery peak systolic velocity on ultrasound. The patient has a family history suggestive of hemolytic anemia. Her blood work shows mild anemia, elevated reticulocyte count, and elevated HbA2 on electrophoresis. Her partner has normal results. The findings are consistent with hemolytic disease of the fetus and newborn HDFN caused by maternal-fetal blood type incompatibility. The mother is Rh and the father is Rh-. The fetus likely inherited Rh- blood type from the father and is experiencing hemolysis from exposure to the mothers Rh antibodies. The question asks which procedure can be used for both diagnosis and treatment. Amniocentesis and chorionic villus sampling are diagnostic only. Fetoscopy and percutaneous fetal thoracentesis could provide therapy by draining fluid, but do not allow definitive diagnosis. Cordocentesis allows sampling of fetal blood to confirm anemia and HDFN, and can also be used therapeutically to transfuse blood products if indicated.D: Cordocentesis
