Endovenous laser treatment treats varicose veins using an optical fiber that is inserted into the vein to be treated, and laser light, normally in the infrared portion of the spectrum, [1] shines into the interior of the vein. This causes the vein to contract, and the optical fiber is slowly withdrawn.
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.
Sclerotherapy is one method for the treatment of spider veins, varicose veins (which are also often treated with surgery, radiofrequency, and laser ablation), and venous malformations. In ultrasound -guided sclerotherapy, ultrasound is used to visualize the underlying vein so the physician can deliver and monitor the injection.
Pregnancy: Pregnancy is a key factor contributing to the formation of varicose and spider veins. Changes in hormone levels are one of the most important reasons women are more likely to develop varicose veins during pregnancy. There is an increase in progesterone, which causes the veins to relax and potentially swell more easily. [6]
Based on the BASIL trial, the ACCF/AHA guidelines recommend balloon angioplasty only for patients with a life expectancy of 2 years or less or those who do not have an autogenous vein available. For patients with a life expectancy greater than 2 of years life, or who have an autogenous vein, a bypass surgery could be performed first. [8]
Blood vessels: Arteries and veins. Most vascular procedures, including all vascular bypass operations (e.g. coronary artery bypass), aneurysmectomy of any type, and all solid organ transplants require vascular anastomoses. An anastomosis connecting an artery to a vein is also used to create an arteriovenous fistula as an access for hemodialysis.
Other causes can include acid reflux, asthma, allergies, or other chronic medical conditions, adds Richard Watkins, M.D., an infectious disease physician and professor of medicine at the Northeast ...
Pelvic congestion syndrome, also known as pelvic vein incompetence, is a long-term condition believed to be due to enlarged veins in the lower abdomen. [1] [7] The condition may cause chronic pain, such as a constant dull ache, which can be worsened by standing or sex. [1] Pain in the legs or lower back may also occur. [1]
