Use of a hemostasis introducer sheath to guide clip delivery during stereotactic directional vacuum-assisted breast biopsy when the biopsy system malfunctions.
Summary of "Use of a hemostasis introducer sheath to guide clip delivery during stereotactic directional vacuum-assisted breast biopsy when the biopsy system malfunctions."
Stereotactic directional vacuum-assisted breast biopsy (ST DVAB) is an accurate biopsy method. Marking the biopsy site with a clip is mandatory after ST DVAB, in case excision is required. With the ST DVAB system we use, clip was delivered through the biopsy probe. We report a case with malfunctioning of the ST DVAB system during the procedure, and thus the clip could not be placed through the biopsy probe. To salvage the procedure, we placed the clip to the biopsy site via a hemostasis introducer sheath.

Medical and Biotech [MESH] Definitions
Myelin Sheath
The lipid-rich sheath surrounding AXONS in both the central and peripheral nervous systems. The myelin sheath is an electrical insulator and allows faster and more energetically efficient conduction of impulses. The sheath is formed by the cell membranes of glial cells (SCHWANN CELLS in the peripheral and OLIGODENDROGLIA in the central nervous system). Deterioration of the sheath in DEMYELINATING DISEASES is a serious clinical problem.
Radiosurgery
A radiological stereotactic technique developed for cutting or destroying tissue by high doses of radiation in place of surgical incisions. It was originally developed for neurosurgery on structures in the brain and its use gradually spread to radiation surgery on extracranial structures as well. The usual rigid needles or probes of stereotactic surgery are replaced with beams of ionizing radiation directed toward a target so as to achieve local tissue destruction.
Hemostasis, Endoscopic
Control of bleeding performed through the channel of the endoscope. Techniques include use of lasers, heater probes, bipolar electrocoagulation, and local injection. Endoscopic hemostasis is commonly used to treat bleeding esophageal and gastrointestinal varices and ulcers.
Neurothekeoma
A benign myxoma of cutaneous nerve sheath origin. Theke is from the Greek theke, sheath. (From Stedman, 25th ed)
Rna Editing
A process that changes the nucleotide sequence of mRNA from that of the DNA template encoding it. Some major classes of RNA editing are as follows: 1, the conversion of cytosine to uracil in mRNA; 2, the addition of variable number of guanines at pre-determined sites; and 3, the addition and deletion of uracils, templated by guide-RNAs (RNA, GUIDE).
