Chronic PJIs may be treated using 1 stage revisions, where the artificial joint is replaced with a new one during the same surgical procedure, or with a 2-stage revision; in which the infected joint is removed and an antibiotic spacer is placed, this is followed by a second surgery in which a new artificial joint is placed.

Open aortic surgery (OAS), also known as open aortic repair (OAR), describes a technique whereby an abdominal, thoracic or retroperitoneal surgical incision is used to visualize and control the aorta for purposes of treatment, usually by the replacement of the affected segment with a prosthetic graft.
Aortic regurgitation, on the other hand, has many causes: degeneration of the cusps, endocarditis, bicuspid aortic valve, aortic root dilatation, trauma, connective tissue disorders such as Marfan syndrome or Ehlers-Danlos lead to imperfect closure of the valve during diastole, hence the blood is returning from the aorta towards the left ...
Diagram of the human heart. Several adaptations of the Ross procedure have evolved, but the principle is essentially the same; to replace a diseased aortic valve with the person's own pulmonary valve (autograft), and replace the person's own pulmonary valve with a pulmonary valve from a cadaver (homograft) or a stentless xenograft.
Aortic valve repair or aortic valve reconstruction is the reconstruction of both form and function of a dysfunctional aortic valve. Most frequently it is used for the treatment of aortic regurgitation. [1] It can also become necessary for the treatment of aortic aneurysm, less frequently for congenital aortic stenosis.
The first line treatment for patients with thoracic aortic injury is maintaining the patient's airway with intubation and treating secondary injuries such as a hemothorax. [4] After ensuring the patient has a patent airway and other life-threatening injuries are treated then treatment for the aortic injury can be started.
Whenever a prosthetic device such as a valve is introduced into the bloodstream, there is an ongoing risk of thrombus formation which can lead to an embolism should the thrombus become mobile. Computational flow studies [21] conclude that the presence of an aortic valve bypass conduit has no effect on cerebral blood flow. All blood flow to the ...
The Bentall procedure is a type of cardiac surgery involving composite graft replacement of the aortic valve, aortic root, and ascending aorta, with re-implantation of the coronary arteries into the graft. This operation is used to treat combined disease of the aortic valve and ascending aorta, including lesions associated with Marfan syndrome.
