Sternotomy
Median sternotomy is a type of surgical procedure in which a vertical inline incision is made along the sternum, after which the sternum itself is divided using a sternal saw. This procedure provides access to the heart and lungs for surgical procedures such as heart transplant, lung transplant, corrective surgery for congenital heart defects, or coronary artery bypass surgery. The median sternotomy was first proposed by Herbert M. N. Milton in 1897. Since the first successful open heart operation in 1953, most cardiac surgeons initially used the bilateral anterior thoracotomy A thoracotomy is a surgical procedure that involves cutting open the chest wall to gain access into the pleural cavity, It is mostly performed by specialist cardiothoracic surgeons, although emergency physicians or paramedics occasionally also ..., which was a very complication-prone and painful approach.

Human Sternum
The sternum (: sternums or sterna) or breastbone is a long flat bone located in the central part of the chest. It connects to the ribs via cartilage and forms the front of the rib cage, thus helping to protect the heart, lungs, and major blood vessels from injury. Shaped roughly like a necktie, it is one of the largest and longest flat bones of the body. Its three regions are the manubrium, the body, and the xiphoid process. The word ''sternum'' originates from Ancient Greek στέρνον (''stérnon'') 'chest'. Structure The sternum is a narrow, flat bone, forming the middle portion of the front of the chest. The top of the sternum supports the clavicles (collarbones) and its edges join with the costal cartilages of the first two pairs of ribs. The inner surface of the sternum is also the attachment of the sternopericardial ligaments. Its top is also connected to the sternocleidomastoid muscle. The sternum consists of three main parts, listed from the top: * Manubr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thoracotomy
A thoracotomy is a surgical procedure that involves cutting open the chest wall to gain access into the pleural cavity, It is mostly performed by specialist cardiothoracic surgeons, although emergency physicians or paramedics occasionally also perform the procedure under life-threatening circumstances. The procedure is performed under general anesthesia with double-lumen intubation, and commonly with epidural analgesia set up pre-sedation for postoperative pain management. The procedure starts with controlled cutting through the skin, intercostal muscles and then parietal pleura, and typically involves transecting at least one rib with a costotome due to the limited range of bucket handle movement each rib has without fracturing. The incised wound is then spread and held apart with a retractor ( rib spreader) to allow passage of surgical instruments and the surgeon's hand. Traditional thoracotomy is thus a highly invasive procedure, with bacterial pneumonia, hemothorax/pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgical Incision
A surgical incision is a cut made through the skin and soft tissue to facilitate an operation or procedure. Often, multiple incisions are possible for an operation. In general, a surgical incision is made as small and unobtrusive as possible to facilitate safe and timely operating conditions and recovery. Anatomy Surgical incisions are planned based on the expected extent of exposure needed for the specific operation planned. Within each region of the body, several incisions are common. Head and neck * Wilde's incision – This post-aural incision is used for a variant mastoiditis drainage, and was named after Sir William Wilde, an ENT surgeon in Dublin who first described it at the end of the nineteenth century. His son, Oscar Wilde's, death was stated by his doctors to be due to meningitis stemming from an ear infection. He had recently had an operation, believed by some to be a mastoidectomy. Chest * Median sternotomy – This is the primary incision used for card ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coronary Artery Bypass Surgery
Coronary artery bypass surgery, also known as coronary artery bypass graft (CABG, pronounced "cabbage"), is a surgical procedure to treat coronary artery disease (CAD), the buildup of plaques in the arteries of the heart. It can relieve chest pain caused by CAD, slow the progression of CAD, and increase life expectancy. It aims to bypass narrowings in heart arteries by using arteries or veins harvested from other parts of the body, thus restoring adequate blood supply to the previously ischemic (deprived of blood) heart. There are two main approaches. The first uses a cardiopulmonary bypass machine, a machine which takes over the functions of the heart and lungs during surgery by circulating blood and oxygen. With the heart in cardioplegic arrest, harvested arteries and veins are used to connect across problematic regions—a construction known as surgical anastomosis. In the second approach, called the off-pump coronary artery bypass (OPCAB), these anastomoses are cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sternal Saw
A sternal saw is a bone cutter used to perform median sternotomy, opening the patient's chest by splitting the breastbone, or sternum. It is a reciprocating blade saw that resembles a jigsaw in appearance. It was invented and introduced by Dr. Edward P. ("Ted") Diethrich in 1963 (see picture of the device in the following external link.

Surgical
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 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, 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 operations typically require a surgi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heart Transplant
A heart transplant, or a cardiac transplant, is a surgical transplant procedure performed on patients with end-stage heart failure when other medical or surgical treatments have failed. , the most common procedure is to take a functioning heart from a recently deceased organ donor (brain death is the most common) and implant it into the patient. The patient's own heart is either removed and replaced with the donor heart ( orthotopic procedure) or, much less commonly, the recipient's diseased heart is left in place to support the donor heart (heterotopic, or "piggyback", transplant procedure). Approximately 5,000 heart transplants are performed each year worldwide, more than half of which are in the US. Post-operative survival periods average 15 years. Heart transplantation is not considered to be a cure for heart disease; rather it is a life-saving treatment intended to improve the quality and duration of life for a recipient.

Lung Transplant
Lung transplantation, or pulmonary transplantation, is a surgical procedure in which one or both lungs are replaced by lungs from a donor. Donor lungs can be retrieved from a living or deceased donor. A living donor can only donate one Lobes of the lung, lung lobe. With some lung diseases, a recipient may only need to receive a single lung. With other lung diseases such as cystic fibrosis, it is imperative that a recipient receive two lungs. While lung transplants carry certain associated risks, they can also extend life expectancy and enhance the quality of life for those with end stage pulmonary disease. Qualifying conditions Lung transplantation is the therapeutic measure of last resort for patients with end-stage lung disease who have exhausted all other available treatments without improvement. A variety of conditions may make such surgery necessary. The most common indications for a lung transplant are pulmonary fibrosis, chronic obstructive pulmonary disease (COPD), cysti ...

Congenital Heart Defect
A congenital heart defect (CHD), also known as a congenital heart anomaly, congenital cardiovascular malformation, and congenital heart disease, is a defect in the structure of the heart or great vessels that is present at birth. A congenital heart defect is classed as a cardiovascular disease. Signs and symptoms depend on the specific type of defect. Symptoms can vary from none to life-threatening. When present, symptoms are variable and may include rapid breathing, bluish skin (cyanosis), poor weight gain, and feeling tired. CHD does not cause chest pain. Most congenital heart defects are not associated with other diseases. A complication of CHD is heart failure. Congenital heart defects are the most common birth defect. In 2015, they were present in 48.9 million people globally. They affect between 4 and 75 per 1,000 live births, depending upon how they are diagnosed. In about 6 to 19 per 1,000 they cause a moderate to severe degree of problems. Congenital heart defects are t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Median Sternotomy Example
The median of a set of numbers is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as the “middle" value. The basic feature of the median in describing data compared to the mean (often simply described as the "average") is that it is not skewed by a small proportion of extremely large or small values, and therefore provides a better representation of the center. Median income, for example, may be a better way to describe the center of the income distribution because increases in the largest incomes alone have no effect on the median. For this reason, the median is of central importance in robust statistics. Median is a 2-quantile; it is the value that partitions a set into two equal parts. Finite set of numbers The median of a finite list of numbers is the "middle" number, when those numbers are listed in order from smallest to greatest. If the data set has an odd numbe ...
