In science, ex vivo refers to experimentation or measurements done in or on tissue from an organism in an external environment with minimal alteration of natural conditions. [ 2 ] A primary advantage of using ex vivo tissues is the ability to perform tests or measurements that would otherwise not be possible or ethical in living subjects.
Ex vivo reconstruction, short for ex vivo renal artery reconstruction and autotransplantation, is a technique mainly used for complex disease involving multiple segmental branches in patients with fibromuscular dysplasia.
This is a laboratory rat with a brain implant, that was used to record in vivo neuronal activity. Studies that are in vivo (Latin for "within the living"; often not italicized in English [1] [2] [3]) are those in which the effects of various biological entities are tested on whole, living organisms or cells, usually animals, including humans, and plants, as opposed to a tissue extract or dead ...
Ex vivo lung perfusion, EVLP, is a form of machine perfusion aimed at sustaining the active aerobic cellular metabolism of donor lungs outside the donor's body prior to lung transplantation. This medical preservation technique typically occurs within a specialised machine engineered to mimic the conditions of the natural circulatory system .
A wedge resection is the non-anatomic removal of a triangular-shaped piece of tissue from the lungs. The utility of wedge resection in NSCLC is disputed. Wedge resection is currently used in NSCLC patients with low pulmonary function, or for pulmonary tuberculosis patients with multiple lesions which do not respect intersegmental boundaries. [13]
A prosection is the dissection of a cadaver (human or animal) or part of a cadaver by an experienced anatomist in order to demonstrate for students anatomic structure. [1] In a dissection, students learn by doing; in a prosection, students learn by either observing a dissection being performed by an experienced anatomist or examining a specimen that has already been dissected by an experienced ...
Robot-assisted surgery or robotic surgery are any types of surgical procedures that are performed using robotic systems. Robotically assisted surgery was developed to try to overcome the limitations of pre-existing minimally-invasive surgical procedures and to enhance the capabilities of surgeons performing open surgery.
A lower anterior resection, formally known as anterior resection of the rectum and colon and anterior excision of the rectum or simply anterior resection (less precise), is a common surgery for rectal cancer and occasionally is performed to remove a diseased or ruptured portion of the intestine in cases of diverticulitis.
