Question

Which procedure coagulates blood inside a varicose vein to collapse and seal it?

1) Commissurotomy

2) Laser ablation

3) Microphlebectomies

4) Ligation and stripping

5) Sclerotherapy

Answer 1

The procedure that coagulates blood in a varicose vein is endovenous thermal ablation, commonly performed through laser ablation, which is the correct answer for collapsing and sealing a varicose vein among the provided options.

Step-by-step explanation:

The procedure that coagulates blood inside a varicose vein to collapse and seal it is known as endovenous thermal ablation. This treatment involves the usage of laser light, radio-frequency energy, or steam to heat the walls of the veins, which causes them to shrink and collapse. Among the options provided in the question, number 2) Laser ablation is the correct answer.

This is a less invasive and often preferable option compared to more invasive surgeries like vein stripping or ligation and stripping. The other options serve different purposes: 1) Commissurotomy is generally related to heart valve surgery, 3) Microphlebectomies involve removing segments of a vein through small incisions, 4) Ligation and stripping is a surgical removal of veins, and 5) Sclerotherapy involves injecting a solution into the vein to cause it to shrink.
