The Vertebral Artery Test or Wallenberg Test is a physical exam for vertebral artery insufficiency. Commonly, the VA test involves cervical spine motion to an end-range position of rotation, extension or a combination of both. At this point, the physician assesses for vertebrobasilar insufficiency (VBI) symptoms.
Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain. The posterior circulation supplies the medulla , pons , midbrain , cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex . [ 1 ]
A beating heart awaiting transplant. American medical researcher Simon Flexner was one of the first people to mention the possibility of heart transplantation. In 1907, he wrote the paper "Tendencies in Pathology," in which he said that it would be possible one day by surgery to replace diseased human organs – including arteries, stomach, kidneys and heart.
In 1984, he performed the world’s first successful paediatric heart transplant. [30] 1994–1995: John Wallwork: Wallwork performed the world's first heart-lung and liver transplant with Sir Roy Calne in 1986. [31] 1995–1996: Sharon Hunt: Pioneered work on post-operative care of heart transplant patients. [32] 1996–1997: William Baumgartner
This means that anyone may receive a transplant of a type-O organ, and consequently, type-O recipients are one of the biggest beneficiaries of ABO-incompatible transplants. [2] While focus has been on infant heart transplants, the principles generally apply to other forms of solid organ transplantation. [3]
A transthoracic echocardiogram (TTE) is the most common type of echocardiogram, which is a still or moving image of the internal parts of the heart using ultrasound.In this case, the probe (or ultrasonic transducer) is placed on the chest or abdomen of the subject to get various views of the heart.
Open heart surgery is a procedure in which the patient's heart is opened and surgery is performed on the internal structures of the heart. It was discovered by Wilfred G. Bigelow of the University of Toronto that the repair of intracardiac pathologies was better done with a bloodless and motionless environment, which means that the heart should ...
Blood compatibility testing is routinely performed before a blood transfusion.The full compatibility testing process involves ABO and RhD (Rh factor) typing; screening for antibodies against other blood group systems; and crossmatching, which involves testing the recipient's blood plasma against the donor's red blood cells as a final check for incompatibility.
