Postperfusion syndrome, also known as "pumphead", is a constellation of neurocognitive impairments attributed to cardiopulmonary bypass (CPB) during cardiac surgery. Symptoms of postperfusion syndrome are subtle and include defects associated with attention, concentration, short-term memory, fine motor function, and speed of mental and motor ...
Coronary artery bypass surgery aims to prevent death from coronary artery disease and improve quality of life by relieving angina, the associated feeling of chest pain. [1] The decision to perform surgery is informed by studies of CABG's efficacy in different patient subgroups, based on the lesions' anatomy or how well the heart is functioning.
These include a sedentary lifestyle, prior surgery, trauma, history of DVT, and hypertension. [31] A sedentary lifestyle and lack of movement are critical modifiable risk factors for PE. [ 32 ] Immobility reduces the rate of leg muscle contraction, enhancing thrombus formation in vessels of the calves that may propagate to the lungs. [ 33 ]
Emergency bypass surgery for the treatment of an acute myocardial infarction (MI) is less common than PCI or thrombolysis. From 1995 to 2004, the percentage of people with cardiogenic shock treated with primary PCI rose from 27.4% to 54.4%, while the increase in coronary artery bypass graft surgery (CABG) was only from 2.1% to 3.2%.

In the legs, bypass grafting is used to treat peripheral vascular disease, acute limb ischemia, aneurysms and trauma.While there are many anatomical arrangements for vascular bypass grafts in the lower extremities depending on the location of the disease, the principle is the same: to restore blood flow to an area without normal flow.
This test helps determine if an angioplasty or bypass surgery is needed. [36] Coronary angiography should only be performed if a patient is a willing to undergo a coronary revascularization procedure. [37] During this test the doctor makes a small incision in the patient's groin or arm and inserts a catheter. [35]
after cardiac surgery 'neurogenic' stunned myocardium following an acute cerebrovascular event such as a subarachnoid hemorrhage; in patients undergoing chronic hemodialysis, chronic myocardial stunning may lead to heart failure; Myocardial stunning has been implicated in the development of Takotsubo (Stress) cardiomyopathy. [1]
VPS occurs more frequently after on pump CABG surgery versus off pump CABG surgery. [1] Hypothermia during surgery may also increase ones risk of developing VPS post operatively. [ 2 ]
