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.

There is no reason to suspect that women with sentinel node biopsy [only] had fewer involved nodes than the women treated with axillary lymph node dissection," Dr.
Prolonged axillary fluid drainage following axillary lymph node dissection is the most common sequelae (30%), which delays the recovery, makes the patient prone for local infection and prolongs the hospital stay enhancing the health budget.
Impact of axillary lymph node dissection on the therapy of breast cancer patients.
Forgoing the standard practice of axillary node dissection when sentinel nodes reveal metastasis constitutes a practice change that "would improve clinical outcomes in thousands of women each year by reducing the complications associated with axillary lymph node dissection and improving quality of life with no diminution in survival," they concluded.
Therefore, until we have good prospective data, we recommend that completion axillary lymph node dissection (ALND) should be performed in these patients to detect residual H&E-positive non-SLN metastases and plan adjuvant chemotherapy.
The evaluation of sentinel lymph nodes (SLNs) in the diagnosis and treatment of breast cancer has become routine at most institutions because patients without SLN involvement can safely avoid an axillary lymph node dissection (ALND).
