Internal jugular vein or subclavian vein.
Because the goal of the procedure is to place a plastic catheter into the vein. If you insert the needle/catheter vertically you will go through the vein. If you angle on insertion once placement in the vein is confirmed you can slide the hollow catheter off of the needle into the vein. The veins used for most IV's normally lie just under the skin. For this reason a shallow angle of insertion is used.
the surgeon inserts a catheter into the varicose vein through a small puncture. The catheter is used to deliver radio frequency energy to the wall of the vein, which causes the vein to contract and seal itself shut.
median cephalic vein
to rest in bed for at least eight hours immediately after the test. If the catheter was inserted into a vein or artery in the leg or groin area, the leg will be kept extended for four to six hours
2/3 of the shoulder-to-umbilical distance
Massive internal bleeding caused by high pressure in the portal vein occurs in about 40% of patients with cirrhosis. Patients who survive are likely to need a portal vein bypass to control bleeding.
When inserting the catheter into veins for IV's, they normally go for peripheral veins, that is, any vein that is not in the chest or abdomen. Sometimes though, when peripheral vascular disease, IV drug abuse, or obesity, to name a few problems/underlying physiological factors, They insert the IV catheter into any available vein.
Most veterinarians first try to place an IV catheter in the front leg, in the superficial vein that runs over the metacarpal bones of the lower forelimb. With a dog in sternal recumbency (lying on his chest bone), you would take your non-dominant hand and use the thumb to apply pressure both down and laterally to stabilize the vein and occlude it so it fills with blood and becomes easier to see. In long-haired dogs, you may need to use some isopropyl alcohol on the area to wet the hair down and allow you to see the vein. In most practices, a technician or assistant will restrain the dog and 'roll the vein' for the veterinarian or technician placing the catheter - this allows the veterinarian to control the paw and increase the venous blood pressure through squeezing the paw. Once you can visualize the vein, place the point of the IV catheter against the skin so that you can see the opening in the needle tip. Firmly and smoothly drive the catheter forward, breaking the skin and the wall of the vein and feeding the IV cathether down the vein. Once the catheter tip is in, release the downward pressure on the vein to allow blood flow to resume; otherwise you end up with a bloody mess and can blow the vein out. Use narrow strips of medical tape to secure the catheter in place and attach fluids or whatever need injecting to the catheter.
A long, flexible tube, called a catheter, is inserted into a vein and threaded up into the heart. The doctor can guide the catheter by watching its movement on a TV monitor showing an x-ray image of the area. The tip of the catheter is fitted with.
The purpose of portal vein bypass surgery is to lower portal hypertension.internal bleeding caused by portal hypertension occurs in about 40% of patients with cirrhosis.Portal vein bypass.is performed on these surviving patients to control bleeding.
Massive internal bleeding caused by portal hypertension occurs in about 40% of patients with cirrhosis. It is initially fatal in at least half of these patients. Portal vein bypass.is performed on these surviving patients to control bleeding.
The catheter goes through it and out the other side causing that section to collapse and blow the vein.

Phlebotomy.phlebotomyphlebotomyIn Medical and Surgical terminology a surgical incision into a vein is called venesection. Another type of vein surgery, called ambulatory phlebotomy, creates an extremely small incision in the skin by the vein. A hook is then inserted through the tiny incision and is used to remove the vein.Laser surgery is often performed when the vein is too small to inject or remove. Light energy is sent into the vein in short bursts, slowly shriveling the vein. The vein then disappears over a small period of time. Laser surgery is very accurate and usually safe for all skin types.One particular vein surgery that can be done inside the doctor's office and usually has a person back to their normal daily activities within one day is called entravenous laser therapy (EVLT). This process involves inserting a tiny laser fiber into the vein where it closes the vein by sending pulsating lasers through it. This treatment is sometimes used in conjunction with other vein surgeries.The VNUS Closure, also known as radio frequency vein ablation, is an alternative treatment that can be performed on an outpatient basis. When a patient undergoes this procedures, an diagnostics ultrasound shows the doctor where to place a catheter inside the vein. Once the catheter is inside the vein, radio frequencies are used to heat the vein and shrink the walls, thus closing the vein. The blood is then rerouted through other healthy veins.

The vein is removed from a lobster tail because it is full of waste. The taste of the vein is not good to many people.
Some thing to do with the kidney dialysis , possibly where the blood comes out of a vein, is de-toxified and returns back to go round the body.
There is a surgery called Vein Ligation. The procedure involves making small incisions where the varicose vein begins and tying off the vein thus cutting off the blood supply to vein making the vein less visible.
