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.

axillary clearance

A procedure in which the lymph nodes and surrounding fat in the axilla are entirely removed as part of a mastectomy for breast cancer. Current evidence suggests that axillary clearance is no more effective than axillary radiation in preventing recurrences or mortality at 10 years.
Cons Lymphoedema, seroma formation, arm swelling, damage to the intercostobrachial nerve, shoulder stiffness, poorer quality of life, and risk of development of angiosarcoma in the region.

axillary lymph node dissection

Surgery The excision of the lymph nodes in the armpit, a procedure commonly performed with mastectomy for breast CA. See Breast cancer.

Though sentinel lymph node biopsy has evolved as an integral part in the management of carcinoma breast, especially in cases of early breast cancer, but Axillary Lymph Node Dissection (ALND) is still an important cornerstone in providing staging and prognostic information.
In the NAC scenario, however, data are limited and guidelines recommend axillary lymph node dissection (ALND) for both cN+/ ycN+ and cN+/ycN0 cases, although the National Surgical Adjuvant Breast and Bowel Project (NSABP) B-18 trial showed that NAC resulted in 301 of 735 patients with positive axillary nodes (41%) compared with 423 of 743 patients (57%) receiving adjuvant chemotherapy.
Of 22 patients with stage II disease, 18 underwent MRM, 3 radical mastectomy and 1 MRM with axillary lymph node dissection. Stage IV cancer patients received palliative intervention and only 6/15 underwent radical mastectomy with axillary lymph node dissection.
