Varicose Veins II: Diagnostic Studies and Interprofessional Care

Varicose Veins II: Diagnostic Studies and Interprofessional Care

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Background:

Intralesional laser therapy has shown promise for vascular malformations (VMs).
Larger studies are needed to establish its role across varied indications.
Previous reports focused on select patient groups.

Purpose of the Study:

To evaluate the safety and efficacy of intralesional laser therapy for VMs.
To analyze treatment response across different VM subtypes and locations.
To identify factors influencing treatment outcomes and complications.

Main Methods:

Retrospective review of 44 patients undergoing 73 intralesional laser treatments (Nd:YAG or diode).
Analysis of lesion characteristics, treatment indications, and outcomes.
Assessment of complications and correlation with patient age and lesion factors.

Main Results:

94% of cases showed lesion size reduction; 91% reported pain improvement.
Venous malformations were most common (66%), primarily in head/neck and lower extremities.
No significant difference in response or complications by VM subtype or location (P > 0.05).

Conclusions:

Intralesional laser therapy is a safe and effective treatment for various vascular malformations.
Age was identified as a risk factor for complications (OR 1.034, P=0.038).
Adherence to guidelines supports successful application in diverse clinical scenarios.
