Bone marrow biopsies with a Silverman needle

Area of Science:

• Hematology
• Surgical Pathology

Background:

• Bone marrow biopsies are crucial for diagnosing hematological disorders.
• Traditional aspiration biopsy may fail in some patients.
• Open surgical biopsy is an invasive alternative.

Purpose of the Study:

• To evaluate the advantages and disadvantages of using the Silverman needle for bone marrow biopsies.
• To assess the efficacy of the Silverman needle in patients with previous failed aspirations.
• To compare the Silverman needle method with open surgical biopsy.

Main Methods:

• Sixty-three bone marrow biopsies were performed using the Silverman needle on the posterior iliac crest.
• Patients included those with prior unsuccessful bone marrow aspirations.
• Local anesthesia was used for all procedures.

Main Results:

• Open surgical biopsy was avoided in 62 out of 63 cases.
• The Silverman needle method was unsuccessful in 12 initial attempts.
• Specimen limitations included crushing artifacts and loss of marrow content.
• Histological material quality was often inferior to aspiration biopsy.

Conclusions:

• The Silverman needle biopsy is a valuable alternative to open biopsy when aspiration fails.
• Despite limitations in specimen quality, it effectively avoids more invasive surgical procedures.
• This technique offers a less invasive option for obtaining bone marrow samples in challenging cases.
