Breast Surgery
Breast surgery is a form of surgery performed on the breast. Types Types include: * Breast augmentation * Breast reduction * Breast-conserving surgery, a less radical cancer surgery than mastectomy * Lumpectomy * Mastectomy * Mastopexy, or breast lift surgery * Microdochectomy (removal of a lactiferous duct) * Surgery for breast abscess, including incision and drainage as well as excision of lactiferous ducts * Surgical breast biopsy Complications After surgical intervention to the breast, complications may arise related to wound healing. As in other types of surgery, hematoma (post-operative bleeding), seroma (fluid accumulation), or incision-site breakdown (wound infection) may occur. Breast hematoma due to an operation will normally resolve with time but should be followed up with more detailed evaluation if it does not. Breast abscess can occur as post-surgical complication, for example after cancer treatment or reduction mammaplasty.Noel Weidner, Chapter ''Infect ...

Surgery
Surgery is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions (e.g., trauma, disease, injury, malignancy), to alter bodily functions (e.g., malabsorption created by bariatric surgery such as gastric bypass), to reconstruct or alter aesthetics and appearance (cosmetic surgery), or to remove unwanted tissue (biology), tissues (body fat, glands, scars or skin tags) or foreign bodies. The act of performing surgery may be called a surgical procedure or surgical operation, or simply "surgery" or "operation". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments, operating theater, surgical facility or surgical nurse. Most surgical procedures are performed by a pair of operators: a surgeon who is the main operator performing the surgery, and a surgical assistant who provides in-procedure manual assistance during surgery. Modern surgical opera ...

Breast Hematoma
Breast hematoma is a collection of blood within the breast. It arises from internal bleeding (hemorrhage) and may arise due to trauma (breast injury or surgery) or due to a non-traumatic cause. Symptoms Symptoms may include visible discoloring ( ecchymosis), breast pain, and swelling. The symptoms may be similar to those of fibrocystic breast changes. Causes A breast hematoma may appear due to direct trauma to the breast, for example from a sports injury or a road accident, for example a vehicle collision in which a seat belt injury occurs. Hematoma can also be a consequence of breast surgery, usually due to post-operative bleeding. Bleeding may occur shortly after the intervention or a number of days later and can occur for cosmetic surgery (for example breast reduction or breast enhancement) and for non-cosmetic surgery (for example lymph node removal, lumpectomy, or mastectomy). More rarely, hematoma can result from breast biopsy. Rarely, a breast hematoma can also ...

General Anaesthesia
General anaesthesia (UK) or general anesthesia (US) is medically induced loss of consciousness that renders a patient unarousable even by painful stimuli. It is achieved through medications, which can be injected or inhaled, often with an analgesic and neuromuscular blocking agent. General anaesthesia is usually performed in an operating theatre to allow surgical procedures that would otherwise be intolerably painful for a patient, or in an intensive care unit or emergency department to facilitate endotracheal intubation and mechanical ventilation in critically ill patients. Depending on the procedure, general anaesthesia may be optional or required. No matter whether the patient prefers to be unconscious or not, certain pain stimuli can lead to involuntary responses from the patient, such as movement or muscle contractions, that make the operation extremely difficult. Thus, for many procedures, general anaesthesia is necessary from a practical point of view. The patient's n ...

Regional Anaesthesia
Local anesthesia is any technique to induce the absence of sensation in a specific part of the body, generally for the aim of inducing local analgesia, i.e. local insensitivity to pain, although other local senses may be affected as well. It allows patients to undergo surgical and dental procedures with reduced pain and distress. In many situations, such as cesarean section, it is safer and therefore superior to general anesthesia. The following terms are often used interchangeably: * ''Local anesthesia'', in a strict sense, is anesthesia of a small part of the body such as a tooth or an area of skin. * ''Regional anesthesia'' is aimed at anesthetizing a larger part of the body such as a leg or arm. * ''Conduction anesthesia'' encompasses a great variety of local and regional anesthetic techniques. Medical A local anesthetic is a drug that causes reversible local anesthesia and a loss of nociception. When it is used on specific nerve pathways (nerve block), effects such as an ...

Negative-pressure Wound Therapy
Negative-pressure wound therapy (NPWT), also known as a vacuum assisted closure (VAC), is a therapeutic technique using a suction (medicine), suction pump, tubing, and a dressing (medical), dressing to remove excess wound exudate and to promote healing in acute or chronic wounds and Burn, second- and third-degree burns. The use of this technique in wound management started in the 1990s and this technique is often recommended for treatment of a range of wounds including Wound dehiscence, dehisced surgical wounds, closed surgical wounds, open abdominal wounds, open fractures, pressure injuries or pressure ulcers, diabetic foot ulcers, Venous insufficiency ulceration, venous insufficiency ulcers, some types of skin grafts, burns, and sternal wounds. It may also be considered after a clean surgery in a person who is obese. NPWT is performed by applying a sub-atmospheric vacuum through a special sealed dressing. The continued vacuum draws out edema, fluid from the wound and increases ...

Fat Necrosis
Fat necrosis is necrosis affecting fat tissue (adipose tissue). The term is well-established in medical terminology despite not denoting a specific pattern of necrosis. Fat necrosis may result from various injuries to adipose tissue, including: physical trauma, enzymatic digestion of adipocytes by lipases, radiation therapy, hypoxia, or inflammation of subcutaneous fat (panniculitis). The gross appearance of fat necrosis is as an irregular, chalky white area within otherwise normal adipose tissue. Pathophysiology Trauma Traumatic injury of adipose tissue liberates stored fat as well as lipases from adipocytes. The extracellular fat then elicits a swift inflammatory response, attracting macrophages and polymorphonuclear leukocytes which proceed to phagocytose the freed fat. The process eventually leads to fibrosis. The necrotic tissue may eventually form a palpable mass (especially if situated at a superficial site like the breast). Traumatic fat necrosis commonly affects ...

Edema
Edema (American English), also spelled oedema (British English), and also known as fluid retention, swelling, dropsy and hydropsy, is the build-up of fluid in the body's tissue (biology), tissue. Most commonly, the legs or arms are affected. Symptoms may include skin that feels tight, the area feeling heavy, and joint stiffness. Other symptoms depend on the underlying cause. Causes may include Chronic venous insufficiency, venous insufficiency, heart failure, kidney problems, hypoalbuminemia, low protein levels, liver problems, deep vein thrombosis, infections, kwashiorkor, angioedema, certain medications, and lymphedema. It may also occur in immobile patients (stroke, spinal cord injury, aging), or with temporary immobility such as prolonged sitting or standing, and during menstruation or pregnancy. The condition is more concerning if it starts suddenly, or pain or shortness of breath is present. Treatment depends on the underlying cause. If the underlying mechanism involve ...

Breast Ultrasound
Breast ultrasound is a medical imaging technique that uses medical ultrasonography to perform imaging of the breast. It can be performed for either diagnostic or screening purposes and can be used with or without a mammogram. In particular, breast ultrasound may be useful for younger women who have denser fibrous breast tissue that may make mammograms more challenging to interpret. Automated whole-breast ultrasound (AWBU) is a technique that produces volumetric images of the breast and is largely independent of operator skill. It utilizes high-frequency ultrasound to help perform a diagnostic evaluation of the lactiferous ducts (duct sonography) and make dilated ducts and intraductal masses visible. Galactography is another technique that can be used to visualize the system of lactiferous ducts and allows a wider area to be visualized. Elastography is a type of ultrasound examination that measures tissue stiffness and can be used to detect tumours. Breast ultrasound is als ...

Cellulitis
Cellulitis is usually a bacterial infection involving the inner layers of the skin. It specifically affects the dermis and subcutaneous fat. Signs and symptoms include an area of redness which increases in size over a few days. The borders of the area of redness are generally not sharp and the skin may be swollen. While the redness often turns white when pressure is applied, this is not always the case. The area of infection is usually painful. Lymphatic vessels may occasionally be involved, and the person may have a fever and feel tired. The legs and face are the most common sites involved, although cellulitis can occur on any part of the body. The leg is typically affected following a break in the skin. Other risk factors include obesity, leg swelling, and old age. For facial infections, a break in the skin beforehand is not usually the case. The bacteria most commonly involved are streptococci and ''Staphylococcus aureus''. In contrast to cellulitis, erysipelas is a bac ...

Axillary Lymph Node
The axillary lymph nodes or armpit lymph nodes are lymph nodes in the human armpit. Between 20 and 49 in number, they drain lymph vessels from the lateral quadrants of the breast, the superficial lymph vessels from thin walls of the chest and the abdomen above the level of the navel, and the vessels from the upper limb. They are divided in several groups according to their location in the armpit. These lymph nodes are clinically significant in breast cancer, and metastases from the breast to the axillary lymph nodes are considered in the staging of the disease. Structure The axillary lymph nodes are arranged in six groups: # Anterior (pectoral) group: Lying along the lower border of the pectoralis minor behind the pectoralis major, these nodes receive lymph vessels from the lateral quadrants of the breast and superficial vessels from the anterolateral abdominal wall above the level of the umbilicus. # Posterior (subscapular) group: Lying in front of the subscapularis muscle, th ...

Lymphedema
Lymphedema, also known as lymphoedema and lymphatic edema, is a condition of localized edema, swelling caused by a compromised lymphatic system. The lymphatic system functions as a critical portion of the body's immune system and returns interstitial fluid to the bloodstream. Lymphedema is most frequently a complication of cancer treatment or parasitic infections, but it can also be seen in a number of genetic disorders. Tissues with lymphedema are at high risk of infection because the lymphatic system has been compromised. Though incurable and progressive, a number of treatments may improve symptoms. This commonly includes compression therapy, good skin care, exercise, and manual lymphatic drainage (MLD), which together are known as combined decongestive therapy. Diuretics are not useful. Signs and symptoms The most common manifestation of lymphedema is soft tissue swelling (edema). As the disorder progresses, worsening edema and skin changes including discoloration, verr ...

Fibrosis
Fibrosis, also known as fibrotic scarring, is the development of fibrous connective tissue in response to an injury. Fibrosis can be a normal connective tissue deposition or excessive tissue deposition caused by a disease. Repeated injuries, chronic inflammation and repair are susceptible to fibrosis, where an accidental excessive accumulation of extracellular matrix components, such as the collagen, is produced by fibroblasts, leading to the formation of a permanent fibrotic scar. In response to injury, this is called scarring, and if fibrosis arises from a single cell line, this is called a fibroma. Physiologically, fibrosis acts to deposit connective tissue, which can interfere with or totally inhibit the normal architecture and function of the underlying organ or tissue. Fibrosis can be used to describe the pathological state of excess deposition of fibrous tissue, as well as the process of connective tissue deposition in healing. Defined by the pathological accumulation of ...
