CHIVA method is a type of surgery used to treat varicose veins that occur as a result of long term venous insufficiency. [1] The term is a French acronym for Conservatrice Hémodynamique de l'Insuffisance Veineuse en Ambulatoire (ambulatory conservative hemodynamic treatment venous insufficiency).
Coronary artery bypass graft surgery has been in practice since the 1960s. Historically, vessels—such as the great saphenous vein in the leg or the radial artery in the arm—were obtained using a traditional "open" procedure that required a single, long incision from groin to ankle, or a "bridging" technique that used three or four smaller incisions.
Permanent vein collapse occurs as a consequence of: [citation needed] Repeated injections, especially with blunt needles. Poor injection technique. Injection of substances which irritate the veins; in particular, fluids that are hypertonic (high osmolality), vasoactive, irritants, with an extreme pH (very acidic / alkaline), [3] or liquid methadone intended for oral use.
A peripherally inserted central catheter, or PICC line (pronounced "pick"), is a central venous catheter inserted into a vein in the arm (via the basilic or cephalic veins) rather than a vein in the neck or chest. The basilic vein is usually a better target for cannulation than the cephalic vein because it is larger and runs a straighter course ...
The development of endovascular surgery has been accompanied by a gradual separation of vascular surgery from its origin in general surgery. Most vascular surgeons would now confine their practice to vascular surgery and, similarly, general surgeons would not be trained or practise the larger vascular surgery operations or most endovascular ...
Superficial vein thrombosis (SVT) extension to the deep vein system and/or recurrence of SVT. Suppurative thrombophlebitis is suspected when erythema extends significantly beyond the margin of the vein and is likely to be associated with significant fever. If suspected, antibiotic treatment, surgical drainage, and potentially vein excision are ...

A synthetic graft remains open in 33 to 50 out of 100 people 5 years after Popliteal bypass surgery was carried out, whereas using veins, the bypass remains unobstructed in 66 out of 100 people. [12] Moreover, the particular vein, great saphenous vein was shown to be more durable over the years after surgery. [ 5 ]
