Venous cutdown procedures most commonly target the great saphenous vein in the leg because it is superficial, easily accessible, and consistently in the same anatomical location. This procedure is used in certain populations such as critically ill patients or patients in hypovolemic shock or when less invasive methods such as peripheral ...
The risk of blood clots is higher in a person with cancer, as cancer is also a risk factor for blood clots. As many as two thirds of cancer patients with central lines show evidence of catheter-associated thrombosis. [3] However, most cases (more than 95%) of catheter-associated thrombosis go undetected.
A peripherally inserted central catheter (PICC or PICC line), also called a percutaneous indwelling central catheter or longline, [1] is a form of intravenous access that can be used for a prolonged period of time (e.g., for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition) or for administration of substances that should not be done peripherally (e.g ...
Cannula transfer or cannulation is a set of air-free techniques used with a Schlenk line, in transferring liquid or solution samples between reaction vessels via cannulae, avoiding atmospheric contamination. While the syringes are not the same as cannulae, the techniques remain relevant.
Throughout the procedure, ultrasound and X-rays are used to ascertain the positioning of the catheter. Potential complications of placement of such a line include hemorrhage and pneumothorax during insertion and thrombosis or infection at later stages.
The cannula used to return oxygenated blood is usually inserted in the ascending aorta, but there is a possibility that it is inserted in the femoral artery, axillary artery, or brachiocephalic artery according to the demand of the surgery. [10] [20] After the cannula is inserted, venous blood is drained from the body by the cannula into a ...
Transcatheter arterial chemoembolization (TACE) is a minimally invasive procedure performed in interventional radiology to restrict a tumor's blood supply. Small embolic particles coated with chemotherapeutic drugs are injected selectively through a catheter into an artery directly supplying the tumor.
The procedure was first described in 1805 by Félix Vicq-d'Azyr, a French surgeon and anatomist. [3] A cricothyrotomy is generally performed by making a vertical incision on the skin of the throat just below the laryngeal prominence (Adam's apple), then making a horizontal incision in the cricothyroid membrane which lies deep to this point.
