Stepwise revascularization for prevention of postoperative hyperperfusion.
Abrupt normalization of cerebral blood flow (CBF) after surgical procedures to improve excessive cerebral hypoperfusion can cause irreversible brain parenchymal damage. Such hyperperfusion, which is caused by inflow at normal blood pressure into maximally dilated fine vessels, is an important complication following carotid endarterectomy (CEA). Strict control of blood pressure in the perioperat...

This sign indicates decreased cerebral perfusion, dilated pial vasculature, and slow leptomeningeal collateral flow. This study aimed to clarify the characteristics of perioperative changes in the ivy sign in relation to cerebral hyperperfusion, which frequently occurs...

متن کامل[Prevention of postoperative adhesions].
Postoperative adhesions represent a common consequence in patients who underwent abdominal or pelvic surgery. Such adhesions can be asymptomatic, but they can cause complications such as chronic abdomino-pelvic pain, secondary infertility, an increase in bowel obstruction risk and more complexity for future surgery, including longer surgery times and an increase in morbidity. Normally, adhesion...
