A 58 year old female patient underwent an intervention of phlebectomy below the knee. The patient gradually developed a severe neurological event and the Glasgow Coma Score decreased dramatically. After two and a half hours from onset, general conditions gradually improved and recovered completely. Lidocaine neurotoxicity was excluded. A right side motor deficit strongly suggests a transient ischaemic attack. As to invasivity, phlebectomy can be compared with liquid and foam sclerotherapy so that the simple question arises of also comparing their adverse effects. We have the strong conviction that this case may only be a co-incidental association. [ABSTRACT FROM AUTHOR]

Published scientific evidence demonstrate the current spread of healthcare misinformation in the most popular social networks and unofficial communication channels. Up to 40% of the medical websites were identified reporting inappropriate information, moreover being shared more than 450,000 times in a 5-year-time frame. The phenomenon is particularly spread in infective diseases medicine, oncology and cardiovascular medicine. The present document is the result of a scientific and educational endeavor by a worldwide group of top experts who selected and analyzed the major issues and related evidence-based facts on vein and lymphatic management. A section of this work is entirely dedicated to the patients and therefore written in layman terms, with the aim of improving public vein-lymphatic awareness. The part dedicated to the medical professionals includes a revision of the current literature, summing up the statements that are fully evidence-based in venous and lymphatic disease management, and suggesting future lines of research to fulfill the still unmet needs. The document has been written following an intense digital interaction among dedicated working groups, leading to an institutional project presentation during the Universal Expo in Dubai, in the occasion of the v-WINter 2022 meeting.

Background: Ultrasound investigation potentials in lymphedema are still to be fully used in everyday practice. Aim of the present study was to report the sonographic characterization of the dermo-epidermal complex (DEC) and of the subcutaneous (SUBC) tissue, assessing the feasibility of a related mapping, in upper limb secondary lymphedema., Methods: In this retrospective study 287 patients affected by monolateral upper limb post-mastectomy lymphedema (M5/F282; mean age 64±4.24) were enrolled and scanned by ultrasound, considering the healthy contralateral limb as control. In order to standardize the assessment, the limb was divided in sectors: 4 anterior, 4 posterior below the elbow, 4 anterior and 4 posterior above the elbow, plus the hand. DEC and SUBC regions B-mode appearance were reported, both in the healthy and in the pathological arms. DEC thickness was measured and compared among the same sectors of the healthy and pathological limbs., Results: DEC and SUBC sonographic appearance was differentiated in fluid and sclerotic. DEC included a third category characterized by differentiation loss. The different sectors showed significantly different lymphatic involvement in the affected limb. In the comparison with the contralateral unaffected segments a significantly thicker DEC was reported in the forearm affected by lymphedema (P<0.005), while no significant difference was reported at the arm level., Conclusions: Traditional ultrasonography can provide a secondary upper limb lymphedema characterization with related mapping and useful data for a better lymphatic physiopathology understanding and for a properly addressed therapeutic protocol.

Objective: This prospective multicenter investigation was conducted to define the repeatability of duplex-based identification of venous reflux and the relative effect of key parameters on the reproducibility of the test., Methods: Repeatability was studied by having the same technologist perform duplicate tests, at the same time of the day, using the same reflux-provoking maneuver and with the patient in the same position. Reproducibility was examined by having two different technologists perform the test at the same time of the day, using the same reflux-provoking maneuver and with the patient in the same position. Facilitated reproducibility was studied by having two different technologists examine the same patients immediately after an educational intervention. Limits of agreement between two duplex scans were studied by changing three elements of the test: time of the day (morning vs afternoon), patient's position (standing vs supine), and reflux initiation (manual vs automatic compression-decompression)., Results: The study enrolled 17 healthy volunteers and 57 patients with primary chronic venous disease. Repeatability of reflux time measurements in deep veins did not significantly differ with the time of day, the patient's position, or the reflux-provoking maneuver. Reflux measurements in the superficial veins were more repeatable (P < .05) when performed in the morning with the patient standing. The agreement between the clinical interpretations significantly depended on a selected cut point (Spearman's ρ, -0.4; P < .01). Interpretations agreed in 93.4% of the replicated measurements when a 0.5-second cut point was selected. The training intervention improved the frequency of agreement to 94.4% (κ = 0.9). Alternations of the time of the duplex scan, the patient's position, and the reflux-provoking maneuver significantly decreased reliability., Conclusions: This study provides evidence to develop a new standard for duplex ultrasound detection of venous reflux. Reports should include information on the time of the test, the patient's position, and the provoking maneuver used. Adopting a uniform cut point of 0.5 second for pathologic reflux can significantly improve the reliability of reflux detection. Implementation of a standard protocol should elevate the minimal standard for agreement between repeated tests from the current 70% to at least 80% and with more rigid standardization, to 90%., (Copyright © 2012 Society for Vascular Surgery.

Objectives: To determine the incidence of side effects following treatment of varicose veins with carbon dioxide-oxygen (CO(2)/O(2)) foam sclerotherapy, and to compare results with historical controls using CO(2)- or air-based foams., Design: Cohort study with prospective data collection, private clinic setting., Patients: The patient population consisted of one hundred patients, 95% women, age 52 SD 13 years-old, CEAP class C(2)EpAsPr., Methods: Patients underwent ultrasound-guided foam sclerotherapy following thermal ablation of saphenous trunks; 1-3% polidocanol and 70%CO(2)-30%O(2) gas were mixed in a 1:4 proportion. Volume injected averaged 22 SD 11 (range: 2-46) mL. Vital signs were monitored for 1 h; side effects were recorded up to 24 h post treatment. Incidence of side effects was compared to CO(2)- and air-based foam data., Results: Heart rate decreased from 73 SD 11 at the start to 68 SD 9 bpm (p < 0.001, paired t-test) following the procedure. Systolic and diastolic pressures, 127/75 SD 18/14 mmHg, respiratory rate, 15 SD 4 rpm and pO(2), 98 SD 2%, did not change significantly. Itching (7) or leg pain (24) reporting was similar to that for air-based foam (p = NS). Lack of reported chest tightness and/or dry cough was superior to our previous data with CO(2) or air foam (p < 0.05). Reporting of dizziness (1) was less than that for air-based foam (p = 0.002). The incidence of visual disturbance (2%), was comparable with that for CO(2) (3%) or air (8%) foam, but too few cases were available for meaningful statistical analysis., Conclusions: Foam sclerotherapy using CO(2)/O(2) foam was well tolerated by patients and resulted in fewer side effects than similar treatment using air foams., (Copyright 2010 European Society for Vascular Surgery.
