Purpose
Bone marrow biopsy remains a key diagnostic step in the workup of hematopoietic and other diseases. This is most often accomplished with a bedside procedure under local anesthesia at the iliac bone and utilizing a manual system. The OnControl powered bone marrow biopsy system was introduced several years ago and has been shown to provide better samples with less pain and decreased procedural time. We seek to demonstrate that fluoroscopically guided powered bone marrow biopsy under moderate sedation in Interventional Radiology (IR) is safe and efficacious.
Materials & Methods
Institutional Review Board approval for this retrospective study was obtained. Imaging and chart review over a two-year period (July 2013-2015) of patients who underwent fluoroscopically guided iliac bone marrow aspiration and core biopsy using the OnControl powered drill system with an 11-gauge needle was performed. Patient demographics, indication/diagnosis, sampling adequacy, fluoroscopy times, pain medication requirements and complications were reviewed.
Results
A total of 161 patients were included (56% female; average age 58.9 years; range 21-91 years) with 183 bone marrow biopsies performed. The most common indications/diagnoses included acute myelogenous leukemia, anemia and pancytopenia. IV moderate sedation was used in all patients with no adverse events. The mean fluoroscopy time was 0.9 minutes (range 0.1-7.0 minutes). Successful aspirate and core biopsy was achieved in 96.2% with no aspirate ('dry tap') in 3.8% of cases. A pathologist deemed 98.9% of specimens adequate. No major or minor complications were encountered. No patients required additional pain medications in the immediate post-procedural period.
Conclusions
In our series, bone marrow biopsy using the OnControl powered drill system yielded high diagnostic sampling accuracy, low fluoroscopy times, excellent patient comfort with moderate sedation and no complications. Our study shows that fluoroscopically guided powered iliac bone marrow biopsy under moderate sedation performed by IRs is a safe and efficacious procedure.
