Clinical, ultrasonographic and histological findings in varicose vein surgery.

Objective: This study aims to correlate the demographic data, different clinical degrees of chronic venous insufficiency (CEAP), ultrasound findings of saphenofemoral junction (SFJ) reflux, and anatomopathological findings of the proximal segment of the great saphenous vein (GSV) extracted from patients with primary chronic venous insufficiency (CVI) submitted to stripping of the great saphenous vein for the treatment of lower limb varicose.

Method: This is a prospective study of 84 patients (110 limbs) who were submitted to the stripping of the great saphenous vein for the treatment of varicose veins of the lower limbs, who were evaluated for CEAP clinical classification, the presence of reflux at the SFJ with Doppler ultrasonography, and histopathological changes. We study the relationship between the histopathological findings of the proximal GSV withdrawal of patients with CVI with a normal GSV control group from cadavers.

Number of Preoperative Hyperhidrosis Sites Does Not Affect the Sympathectomy Postoperative Results and Compensatory Hyperhidrosis Occurrence.

Background:  Patients with primary hyperhidrosis present with sweating in two or more sites in nearly 85% of cases. In this study, we examined whether the number of hyperhidrosis sites is related to the surgery outcomes.

Methods:  One hundred ninety-three hyperhidrosis patients who underwent bilateral videothoracoscopic sympathectomy after failure or dissatisfaction with clinical treatment were distributed into three groups based on the number of hyperhidrosis sites (one site, two sites, and three or more sites of hyperhidrosis).

The relation between age and outcomes of thoracic sympathectomy for hyperhidrosis: The older the better.

Objective: Several factors may potentially influence the efficacy and patient satisfaction after bilateral thoracic sympathectomy as the treatment for hyperhidrosis, but few studies have specifically analyzed the impact of age on the efficacy of this treatment, the occurrence of compensatory hyperhidrosis (CH), and variations in the quality of life.

Methods: We retrospectively analyzed the effect of age, body mass index, surgical techniques, quality of life before surgery, betterment in the quality of life after surgery, clinical improvement in sweating at the main site, and the occurrence and intensity of CH in patients with hyperhidrosis (n = 1633) who underwent bilateral sympathectomy.

Results: Quality of life improved in more than 90% of patients, and severe CH occurred in 5.
