The insertion site of the IJV is fixed between the two heads (sternal and clavicular heads) of the sternocleidomastoid. 2% lignocaine is to infiltrate the puncture site. Using a 24G needle attached to 5 cc syringe, the needle is advanced through the puncture site with its tip pointing towards the nipple of the same side.
Following the procedure, the prostatic tissue will be swollen and irritated. Urologists often place a Foley catheter to prevent the patient from having urinary retention. After three to five days the Foley catheter can be replaced by a temporary prostatic stent to improve voiding without exacerbating irritation symptoms.
Catheter access, sometimes called a CVC (central venous catheter), consists of a plastic catheter with two lumens (or occasionally two separate catheters) which is inserted into a large vein (usually the vena cava, via the internal jugular vein or the femoral vein) to allow large flows of blood to be withdrawn from one lumen, to enter the dialysis circuit, and to be returned via the other lumen.
It has less impact on a person's activities than a PICC line or a tunneled catheter. Surgically implanted infusion ports are placed below the clavicle (infraclavicular fossa), with the catheter threaded into the heart (right atrium) through a large vein. Once implanted, the port is accessed via noncoring "Huber" needles inserted through the skin.
Types of epidural needles include: [3] The Crawford Needle; The Tuohy Needle; The Hustead Needle; The Weiss Needle; The Sprotte Spezial Needle; Other Epidural Needles : Other less popular types are the Wagner needle (1957), the Cheng needle(1958), the Crawley needle (1968), the Foldes needle (1973), and the Bell needle (1975)—all variants of the Huber design with a blunted tip of varying ...

It is performed by treating the area with an antiseptic, such as iodine-based solution, and then making a small incision to puncture the skin using a sterile instrument such as a sharp needle or a pointed scalpel. This allows the pus to escape by draining out through the incision.
A TIPS procedure decreases the effective vascular resistance of the liver through the creation of an alternative pathway for portal venous circulation. By creating a shunt from the portal vein to the hepatic vein, this intervention allows portal blood an alternative avenue for draining into systemic circulation.
