BACKGROUND: The aim of our study was to comparatively assess volume changes related to daily occupation of the whole leg (WLv), of the lower leg (LLv) and of the upper leg (ULv) in subject with no venous and lymphatic disorders. METHOD: WLv, LLv, and Ulv were evaluated by water displacement volumetry (WDV) in the morning and in the evening in 20 healthy subjects. RESULTS: In the legs with occupational edema (OE), WLv increased by 7.07%, LLv by 5.25%, and ULv by 9.80%. In legs without clear OE, WLv increased by 2.41%, LLv by 1.35, and ULv by 3.38%. CONCLUSIONS: Surprisingly, the increase of ULv was greater than that of LLv. An evening increase in the leg volume also occurred in legs with no clear OE. In our series, a clinically evident OE was related to an increase of the WLv, LLv, and ULv greater than 5.83%, 8.68%, and 1.88%, respectively.
BACKGROUND: The decision to treat a refluxing anterior saphenous vein (ASV) should be a clinical decision based on the assessment on the ASV's contribution to patient's signs and symptoms. Once the decision to treat has been made, there are anatomic, clinical, and technical considerations in treatment planning. METHODS: Clinical scenarios were discussed by a panel of experts and common anatomic, clinical, and technical considerations were identified. RESULTS: There are unique clinical considerations such as whether both the great saphenous vein (GSV) and ASV should be concomitantly treated, if a normal ASV should be treated when treating a refluxing GSV and when and how to treat the associated tributary varicose tributaries. Being aware of the anatomic, clinical, and technical considerations allows development of a treatment plan that optimizes long-term outcomes in patients with ASV reflux. CONCLUSIONS: Ultimately the treatment plan should be tailored to address these types of variables in a patient-centered discussion.

OBJECTIVE: The objective of this study is to systemically review the literature on Anterior Saphenous Vein (ASV) reflux treatment and insurance impediments to treatment coverage. METHODS: A literature search was performed using a PRISMA framework. In addition, a cross-sectional analysis of insurance policies for ASV treatment was evaluated. RESULTS: Published evidence and treatment considerations in the literature for ASV treatment are discussed. In 155 of 226 (68.6%) insurance policies reviewed coverage of ASV ablation was allowed while 62/226 (27.4%) did not specify coverage and 9/226 (4.0%) specified ASV treatment was not covered. Of the 155 that provide ASV coverage, 98 (62.2%) provide coverage with criteria such as requiring prior treatment of the great saphenous vein. CONCLUSIONS: Vein treatment experts should continue to advocate to insurance carriers to update their varicose vein treatment policies to reflect the substantial clinical evidence so that patients with ASV reflux can be appropriately treated.

BACKGROUND: The term Anterior Accessory of the Great Saphenous Vein suggests this is a branch tributary vein despite this vessel's anatomic features of a truncal vein. A multisocietal group suggested to designate this the anterior saphenous vein (ASV). This study was aimed to evaluate its ultrasound anatomy in normal and varicose limbs. METHODS: The clinical anatomy of the ASV was evaluated by narrative review of the literature. Additionally, the course of the ASV was evaluated in 62 limbs with no evidence of venous disease and 62 limbs with varicosities. RESULTS: The ASV length, patterns of origin and termination are reported in both normal and patients with varicose veins. Discussion of the patterns is supported by the narrative review of the literature. CONCLUSIONS: The ASV must be considered a truncal vein and its treatment modalities should be the same that for the great and small saphenous veins rather than a tributary vein.

BACKGROUND: There is a lack of clarity regarding the terminology of the anterior accessory saphenous vein (AASV) that can impact treatment outcomes. Although use of the word "accessory" implies that the vein is a superficial tributary, evidence supports its role as a truncal vein, similar to the great and small saphenous veins, and warranting a change in terminology. METHODS: A multisocietal panel was convened by the American Vein and Lymphatic Society (AVLS), the Union International of Phlebology (UIP), and the American Venous Forum (AVF). The group was charged with reviewing the existing anatomic and clinical literature pertaining to the term "anterior accessory saphenous vein" and to consider the need for alternative terminology. CONCLUSION: Based on the insights gathered from the literature review and extensive discussions, the panel recommends changing the terminology such that the "anterior accessory saphenous vein" (AASV) now be designated the anterior saphenous vein (ASV).
OBJECTIVE: Although compression therapy (CT) is considered a crucial conservative treatment in chronic venous disease, strong evidence is missing for many clinical indications. This literature review aims to point out what strong evidence we have for CT and all the clinical scenarios where strong evidence still needs to be included. METHODS: The research was conducted on MEDLINE with PubMed, Scopus and Web of Science. The time range was set between January 1980 and October 2022. Only articles in English were included. RESULTS: The main problem with CT is the low scientific quality of many studies on compression. Consequently, we have robust data on the effectiveness of CT only for advanced venous insufficiency (C3-C6), deep vein thrombosis and lymphedema. We have data on the efficacy of compression for venous symptoms control and in sports recovery, but the low quality of studies cannot result in a strong recommendation. For compression in postvenous procedures, superficial venous thrombosis, thromboprophylaxis, post-thrombotic syndrome prevention and treatment, and sports performance, we have either no data or very debated data not allowing any recommendation. CONCLUSIONS: We need high-level scientific studies to assess if CT can be effective or definitely ineffective in the clinical indications where we still have a paucity of or contrasting data.

Chronic venous disorders (CVD) of the lower limbs can be treated with different strategies. Typically, conservative management is based on compression therapy, anticoagulants and venoactive drugs. Endovenous treatments remain the gold standard to treat saphenous insufficiency, with sclerotherapy and surgery maintaining a role in selected cases. In addition, several 'unconventional' approaches have been proposed to prevent CVD progression and complications, minimize symptoms and improve the quality of life and postoperative outcomes. Among these, balneotherapy and aquatic exercises are proving as valid and effective supporting treatments, as mentioned in a growing number of scientific publications. Moreover, aquatic protocols have been studied for both venous and lymphatic insufficiency. For these reasons, they were mentioned in the last CVD guidelines provided by the European Society for Vascular Surgery. The aim of this narrative review is to overview and summarize current literature evidences on the role and effectiveness of aquatic rehabilitative protocols in CVD, reviewing old and current literature. Furthermore, the physical basis of the effects of water immersion on lower limb venous and tissues modifications are also described.

OBJECTIVES: The occurrence of leg edema in patients with chronic venous disease (CVD) is currently evaluated by visual inspection, palpation, and measurement of limb circumference. The changes of soft tissues morphology in swollen legs have been poorly investigated by ultrasonography (US) in the past. The purpose of this study was to evaluate the effects of medical compression stockings (MCS) on the US morphology of the cutaneous and subcutaneous layers (CL and SCL, respectively) in legs with venous edema. METHODS: The morphology of the cutaneous and subcutaneous layers (CL and SCL) was evaluated by US in 18 swollen legs with chronic venous disorders (CVD), before and after 4 weeks of treatment with MCS. Skin morphology was evaluated by using an 8-14 MHz probe with a dedicated setting, 5 cm above the medial malleolus. RESULTS: MCS provoked both quantitative and qualitative changes. A reduction of CL/SCL thickness greater than 20% was observed in 16/18 legs. A reduction of the SCL echogenicity was observed in 14/18 legs. Nine out of 12 legs which showed abnormalities of the CL before treatment showed a structural rearrangement of the dermis and the reappearing of the dermo-hypodermic junction. CONCLUSIONS: The reduction of the SCL thickness is to be ascribed to the increase of veno-lymphatic drainage promoted by MCS. The reduction of tissue echogenicity by MCS is a quite innovative concept and it is suggestive for an anti-inflammatory action of MCS on skin tissues.
BACKGROUND: Calcifications in the subcutaneous layer (SCL) have been described by radiographic studies of legs with advanced chronic venous disease (CVD). However, SCL calcifications have rarely been included among the CVD-related changes. The aim of the present study was to evaluate the prevalence and morphology of SCL calcifications in legs with CVD of all grades of severity determined by ultrasound. METHODS: A total of 500 legs in 250 patients (148 women and 102 men; mean age, 51 years; range, 18-87 years) referred to our vascular clinic for symptoms and signs of CVD were included. After duplex ultrasound evaluation of the deep, superficial, and perforating veins, the skin and SCL were investigated using duplex ultrasound. Those patients with other possible causes of SCL calcification were excluded. RESULTS: Using the C component of the CEAP (clinical, etiologic, anatomic, pathophysiologic) classification, 43 legs were classified as C1, 189 as C2, 34 as C3, 16 as C4A, 45 as C4B or C, 18 as C5, and 16 as C6. Varicose veins were reported in 273 legs, and lipodermatosclerosis in 79 legs. Subcutaneous calcifications were demonstrated in 35 of 361 legs with CVD in two different locations: the wall of superficial varicose veins and in subcutaneous tissue unrelated to the path of the superficial veins. Superficial veins calcifications were found in 12 of 273 legs with varicose veins (4.4%) and were found in older patients with severe varicose vein disease (grade 3 using the venous clinical severity score and disease duration >30 years). Subcutaneous tissue calcifications (STCs) were found in 24 of 95 legs with a more advanced CVD stage (C4A-C6). No STCs were found in legs with a C1, C2, or C3 class. CONCLUSIONS: Superficial veins calcifications were found only in the legs with severe and long-lasting varicose veins and seemed to be related to chronic severe inflammation of the venous wall. STCs were independent of the vein wall and were found only in the damaged areas of legs with severe CVD (C4-C6). STCs are possibly related to chronic inflammation of the subcutaneous tissue. Their avulsion from the ulcer bed has been recommended to facilitate ulcer healing and prevent recurrence.

BACKGROUND: Balneotherapy has been considered beneficial in patients with chronic venous disease due to patient-reported positive outcomes on improvement of symptoms and quality of life.Study aim: Assessing the effects of prolonged water immersion (WI) on leg edema and epifascial thickness and to compare these data with those achieved after continuous walking on ground. MATERIAL AND METHODS: On three consecutive days, 14 otherwise healthy volunteers (9 females, 5 males, mean age 53 ± 10 years) affected by occupational edema (OE), defined as the edema developing during the time period of the working day and disappearing overnight, stayed standing immobile in a swimming pool for 30 minutes (30'), continuously walking again for 30' in the same pool and walking on ground for 30' without interruptions in a randomized sequence. Leg volume, ankle circumference and epifascial thickness of both legs were assessed each day before and after each intervention. RESULTS: Leg volume showed a median reduction by 4.20% (IQR 5-3.6) (p = 0.0002) after 30' of immobile standing immersion and by 6.50% (IQR 7.30-5.61) (P < 0.0001) when the patients walked in the pool. Ankle circumference showed a median reduction by 2.89% (IQR 4.23-2.03) (p = 0.02) with the subjects staying standing still in water and by 5.98% (IQR 7.47-4.14) (p = 0.0002) after 30' walking in the pool. Epifascial thickness showed a median reduction by 24.35% (IQR 35.26-22.5) (P < 0.0001) when the volunteers remained standing still and by 32.66% (IQR 36.91-28-84) (P < 0.0001), when walking in water. Leg volumetry showed a median reduction by 0.20% (IQR-0.44-0.29) (p = 0.375) after walking on ground for 30'. Ankle circumference and epifascial thickness did not show any difference walking on ground compared to baseline situation. CONCLUSIONS: This study showed that 30' of WI, especially when associated with walking, reduced leg volume in otherwise heathy subjects with OE and that walking outside the water did not.

BACKGROUND: Strain gauge plethysmography (SGP) is employed to evaluate venous drainage of the lower leg. METHODS: In this study, SGP was used to evaluate the effects of the hydrostatic pressure (HP) of water on venous volume (VV), expelled volume, and ejection fraction (EF) in 22 healthy legs before and during immersion in water. RESULTS: HP reduced VV by 100% and even more during underwater (UW) exercise, making calculation of the UW EF possible. DISCUSSION: UW SGP is feasible and indicates that HP improves venous haemodynamics. This study suggests that including UW leg exercise in the rehabilitation protocols of patients with chronic venous disease may be useful. KEYWORDS: Strain gauge plethysmography, Underwater compression, Underwater ejection fraction, Underwater venous volume.
OBJECTIVE: To evaluate by Doppler ultrasound (DUS) the venous intima-media thickness (vIMT) in patients with or without great saphenous vein (GSV) incompetence. METHODS: A prospective vIMT measurement was performed by DUS in an outpatient cohort. Patients were divided in two groups: group A, patients without GSV reflux; and group B, patients with at least one refluxing GSV. Group B was further divided in group B1, patients with monolateral refluxing GSV; and group B2, patients with bilateral GSV reflux. The vIMT was measured in the femoral vein (FV), 3 to 5 cm distal to the saphenofemoral junction (vIMT[FV]), and in the GSV, 3 to 5 cm from saphenofemoral junction (vIMT[R-] or vIMT[R+]) in the case of a nonrefluxing or a refluxing GSV, respectively. Only one limb per patient was considered for vIMT analysis: in group A, the limb with the greater vIMT(R-), in subgroup B1 the limb with a refluxing GSV, and in subgroup B2 the limb with the lower vIMT(R+). The primary outcome was the difference of vIMT of GSV between groups A and B. Secondary outcomes were differences in vIMT(FV) among groups and the correlation between vIMT of GSV and demographic or clinical parameters. A subgroup analysis of vIMT in GSV was conducted in B1 patients, describing vIMT variations in both limbs. RESULTS: Forty-four patients were enrolled. In the group A (26 patients), vIMT of the GSV was lower than in the group B (18 patients; 0.31 ± 0.01 mm vs 0.49 ± 0.02 mm; P < .001). The difference was significant also for vIMT(FV) (group A, 0.67 ± 0.02 mm vs group B, 0.77 ± 0.03 mm; P < .014). No statistical correlation between age, body mass index, family history, or use of elastic stockings and vIMT(FV) or vIMT(R+ or R-) was detected. Considering the whole population, vIMT of GSV was higher in patients with Clinical, Etiology, Anatomy and Pathophysiology (CEAP) class C of 2 or greater than in classes C 0 and 1 (0.43 ± 0.02 mm vs 0.32 ± 0.02 mm; P < .0002). The difference was significant also for vIMT(FV) in patients with class a class C of 2 or greater and C of 0 to 1 (0.77 ± 0.02 mm vs 0.64 ± 0.03 mm; P < .0008, respectively). In group B1, vIMT(R+) was higher than vIMT(R-) (0.50 ± 0.02 mm vs 0.32 ± 0.02 mm, respectively; P < .0001). The difference was not significant for vIMT(FV). CONCLUSIONS: vIMT seems to be an indirect marker of saphenous insufficiency. In GSV incompetence, an augmented wall thickening is visible in the FV as well. Further studies are needed to assess the accuracy of DUS measurements of vIMT. Longitudinal studies are also needed to evaluate possible GSV and FV vIMT variations related to disease progression or treatment.

Verrucous hyperplasia of the skin rarely occurs in legs with severe venous stasis. In these cases, ultrasound demonstrated thickening and hyperechogenicity of the skin layers. The core of the verrucous-like protrusions consisted of a fibrous lump of the reticular dermis, surrounded by an anechogenic layer and covered by a thickened epidermal shell. Compression treatment provokes the progressive disappearance of the dermal plications, accompanied by reduction of the cutaneous and subcutaneous edema and infiltration. Ultrasound easily demonstrates the histologic changes of verrucous hyperplasia of the skin and allows evaluation of the evolution of the disease and the efficacy of treatments.
OBJECTIVES: Hydrostatic compression (HC) occurring during body immersion is considered beneficial for venous return from the lower limbs. No study has evaluated the effects of HC on the veins of the lower limbs using duplex ultrasound (DU). The purpose of this study was to use DU to evaluate the morphology and flow of the leg veins during immersion. DESIGN: The femoral and great saphenous veins were evaluated before and during immersion in a specifically built pool, in normal and varicose limbs. RESULTS: HC reduces vein size in both normal and varicose limbs. During immersion spontaneous flow increases whereas when present, blood reflux decreases. DISCUSSION: This pilot, proof of concept study has demonstrated the feasibility of DU investigation of leg veins during immersion. Larger series of underwater DU evaluations of normal and varicose legs are necessary to quantify and better explain the effects of HC on the veins of the lower limb.
BACKGROUND: To date, no document comprehensively focused on the complex issue of the rehabilitation of chronic venous diseases of the lower limbs. METHOD: This article overviews and summarizes current strategies concerning venous rehabilitation of lower limbs. RESULTS: Venous rehabilitation is based on four main strategies: (1) lifestyle adaptations and occupational therapies; (2) physical therapies; (3) adapted physical activities; (4) psychological and social support. Rehabilitative protocols must be tailored to the specific needs of each patient, depending on the severity of chronic venous disease and on the location and pattern of venous lesion(s), but also on age, motor deficits, co-morbidities and psychosocial conditions. CONCLUSIONS: Venous rehabilitation consists of non-pharmacologic and non-surgical interventions aiming at prevention of venous disease progression and complications, reduction of symptoms and improvement of quality of life. Well-designed clinical trials are required to evaluate the efficacy of the described rehabilitative protocols in influencing the evolution of venous disorders.
