dissection

 [dĭ-sek´shun]
1. the act of dissecting.
2. a part or whole of an organism prepared by dissecting.
aortic dissection a dissecting aneurysm of the aorta; the usual site is the thoracic aorta. There are two types, classified according to anatomical location: Type A involves the ascending aorta; Type B originates in the descending aorta. Acute aortic dissection is often fatal within one month of onset. Surgical treatment may be delayed in aneurysms involving the descending aorta until the blood pressure has been controlled and edema and friability of the aorta are diminished. The usual course of treatment for an aneurysm of the ascending aorta is immediate surgery. The surgical procedure for either type is aimed at either repairing the intimal tear or removing the affected portion of the aorta. This may be done by suturing the separated aortic layers back together or by removing the damaged section of the aorta and replacing it with a synthetic graft.
axillary dissection (axillary lymph node dissection) surgical removal of axillary lymph nodes, done as part of radical mastectomy.
blunt dissection separation of tissues along natural lines of cleavage, by means of a blunt instrument or finger.
lymph node dissection lymphadenectomy.
lymph node dissection, retroperitoneal (RPLND) retroperitoneal lymphadenectomy.
sharp dissection separation of tissues by means of the sharp edge of a knife or scalpel, or with scissors.

Can axillary dissection be avoided in patients with sentinel lymph node metastasis?
In recent studies, axillary dissection (not the mastectomy or quadrantectomy) has been demonstrated to be a risk factor for persistent pain after treatment and sensory disturbances compared with sentinel lymph node biopsy [6, 7,17].
Axillary dissection with mastectomy or BCT followed by appropriate adjuvant therapy is recommended.
Allergic reactions were reported in a randomised controlled trial from North America comparing sentinel node biopsy-based treatment with axillary dissection in women with early breast cancer (4).
In a study of suction drains in patients who underwent breast surgery with axillary dissection, Barwell et al reported that (1) seromas were associated with larger total drainage volumes, (2) keeping drains in for longer periods (drains were kept in for a median of 4 days) did not protect against seroma formation, and (3) prolonged suction drainage only delayed patient discharge.
Even women with positive sentinel lymph nodes can often be treated safely and effectively without further axillary dissection, say researchers, after a trial suggested that aggressive removal of lymph nodes did not prevent recurrence or prolong survival.
Whilst SNB is the procedure of choice in clinically node-negative breast cancer, preoperative radiological staging of the axilla is important because axillary dissection is the recommended treatment for those with axillary metastases, and because it is in cases where nodes are heavily infiltrated with tumour that SNB is most likely to produce a false-negative result.
The accepted treatment for early-stage breast cancer in women with breast implants--skin-sparing mastectomy with axillary dissection and implant exchange followed by WBI--carries a 55% risk of capsular contracture due to the formation of collagenous scar tissue around the implant, Dr.
Subjects were 3,088 women aged 18-70 years who had been treated with axillary dissection and total mastectomy or lumpectomy followed by radiation at seven medical centers between 1995 and 2000.
