Why Do I Need A Bone Marrow Biopsy Needle?

A bone marrow biopsy, or a bone marrow biopsy, uses a special puncture needle to take a small cylindrical piece of bone marrow about 0.5 to 1 centimeter long for pathological examination. The operation method is basically the same as that of bone marrow puncture. The extracted material maintains the complete structure of bone marrow tissue, which can make up for the deficiency of bone marrow puncture. Has the following advantages:
1) Maintain the natural structure of hematopoietic tissue, which is convenient to judge the proportion of red pulp and adipose tissue;
2) A comprehensive understanding of the degree of bone marrow hyperplasia, nucleated cell density and its layout;
3) Can avoid the dilution of blood sinus;
4) It can assist in the diagnosis of myelofibrosis, hair-cell leukemia, bone marrow necrosis, and bone marrow steatosis, and can indicate the transformation of myelodysplastic syndrome to acute myelogenous leukemia. It can differentiate "dry extraction". Therefore, bone marrow biopsy can not only understand the composition of bone marrow cells and the distribution of primitive cells, but also observe the cell morphology, which is convenient for pathological diagnosis, and provide important diagnostic basis for hard-to-diagnose diseases such as aplastic anemia, myelodysplastic syndrome, and bone marrow aspiration dry extraction.
Bone marrow aspiration and bone marrow biopsy have their own advantages and disadvantages. They are two important means of diagnosing hematological diseases which cannot be replaced by each other. Bone marrow biopsy is also relatively easy, for the elderly can cooperate with children can be carried out more smoothly, for infants and children to carry out certain difficulties. The biopsy procedure may be slightly longer than the bone marrow aspiration, and there may be a feeling of distension during the biopsy. After the puncture, the patient could move normally after the hemostasis with pressure dressing
