Detaljeret beskrivelse
Reticular veins and telangiectasias (spider veins) represent common chronic venous disorders affecting a large proportion of the adult population, particularly women.
The Cryo-Laser and Cryo-Sclerotherapy (CLaCS) technique has emerged as an innovative method combining transdermal laser therapy, injection sclerotherapy, and skin cooling. This multimodal approach enhances visualization of feeder veins using augmented reality or vein illumination systems, allowing precise targeting and improved clearance rates. Cooling reduces pain and protects the epidermis, making the procedure more tolerable and safer.
Nd:YAG laser (1064 nm) is considered the cornerstone of the CLaCS technique due to its deeper penetration and selective photothermolysis of hemoglobin. It effectively targets deeper reticular veins (up to 3-4 mm depth), induces vessel wall contraction, and facilitates subsequent sclerotherapy.

Hvad måler undersøgelsen?
Primære resultatmål
Resultatmål |
Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Degree of vein clearance
Tidsramme: 6 months postoperatively
|
Degree of vein clearance will be assessed by immediate endpoint response during laser application, defined as either instantaneous disappearance of the vein or an immediate change in vein color.
|
6 months postoperatively

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Grad af patienttilfredshed
Tidsramme: 6 måneder postoperativt
|
Grad af patienttilfredshed vil blive vurderet på en 5-punkts Likert-skala-patienttilfredshed (1, ekstremt utilfreds; 2, utilfreds; 3, neutral; 4, tilfreds; 5, ekstremt tilfreds).
|
6 måneder postoperativt
