The objective of the study was to review the literature reporting visual disturbance (VD) following sclerotherapy for varicose veins. Underlying mechanisms will be discussed. A literature search of the databases Medline and Google Scholar was performed. Original articles including randomized trials, case series and case reports reporting VD in humans following sclerotherapy for varicose veins were included. Additional references were also obtained if they had been referenced in related publications. The search yielded 4948 results of which 25 reports were found to meet the inclusion criteria. In larger series with at least 500 included patients the prevalence of VD following sclerotherapy ranges from 0.09% to 2%. In most reports foam sclerotherapy was associated with VD (19); exclusive use of liquid sclerosant was reported in two cases, some reports included foam and liquid sclerosant (4). There were no persistent visual disorders reported. VD occurred with polidocanol and sodium tetradecyl sulphate in different concentrations (0.25–3%). Various forms of foam preparation including various ways of foam production and the liquid – air ratio (1 or 2 parts of liquid mixed with 3, 4 or 5 parts of air) were reported in association with the occurrence of VD. VDs following sclerotherapy for varicose veins are rare and all reported events were transient. Bubble embolism or any kind of embolism seems unlikely to be the only underlying mechanism. A systemic inflammatory response following sclerotherapy has been suggested. Further research to clarify the mechanism of action of sclerosants is required.
This is a retrospective study over 12 years reporting the healing rates of leg ulcers at a specialist vein unit. All patients presented with active chronic venous leg ulcers (clinical, aetiological, anatomical and pathological elements [CEAP]: C6) and had previously been advised elsewhere that their ulcers were amenable to conservative measures only.
Seventy-two patients (84 limbs) were treated between March 1999 and June 2011. Patients were contacted in August 2011 by questionnaire and telephone. Of 72 patients, two were deceased and two had moved location at follow-up, so were not contactable. Fifty patients replied and 18 did not (response rate 74%), representing a mean follow-up time of 3.1 years.
Ulcer healing occurred in 85% (44 of 52 limbs) of which 52% (27) limbs were no longer confined to compression. Clinical improvement was achieved in 98% of limbs.
This study shows that a significant proportion of ulcers currently managed conservatively can be healed by surgical intervention.
The ESCHAR trial showed that superficial venous surgery and compression in chronic venous ulceration achieved a 24-week healing rate of 65% and 12-month recurrence rate of 12%. Foam sclerotherapy treatment is an alternative to surgery. The aim of this study is to assess the effect of foam sclerotherapy on ulcer healing and recurrence in chronic venous leg ulcers.
Chronic venous leg ulcers (CEAP [clinical, aetiological, anatomical and pathological elements] 5 and CEAP 6) with superficial venous reflux were treated between March 2006 and June 2011 with ultrasound-guided foam sclerotherapy and compression. Venous duplex was performed on all legs before and after treatment. Twenty-four-week ulcer healing and one- and four-year ulcer recurrence rates were calculated using Kaplan–Meier survival analysis.
Two hundred legs (186 patients) with chronic venous ulcers (CEAP 5:
Foam sclerotherapy is effective in abolition of superficial venous reflux and may contribute to similar ulcer healing and long-term recurrence rates to superficial venous surgery. Foam sclerotherapy is an attractive alternative to surgery in this group of patients.
To evaluate the efficacy and safety of intralesional injection of pingyangmycin for the treatment of microcystic lymphatic malformations (LMs) in the tongue.
Eighteen patients with tongue microcystic LMs were treated with intralesional injection of pingyangmycin. The concentration of the drug was 1 mg/mL with an addition of dexamethasone. Repeated injections were performed at an interval of 3–4 weeks. The results were evaluated by clinical examinations and Doppler ultrasonography scan. The follow-up period was 12 months to eight years after the last treatment and the mean follow-up time was three years. All patients received 1–8 injections (mean, 3.0 injections) for the whole course of treatment. The total dose of pingyangmycin administered was 8–64 mg (mean, 24 mg).
Fifteen patients had complete response with no cosmetic or functional problems. Three patients with macroglossia had a reduction of 50–90% in the lesion size and needed secondary surgery. No serious complications were encountered.
The results suggested that intralesional injection of pingyangmycin is an effective and safe treatment for microcystic LMs in the tongue, and can be used as the first-line treatment protocol.
Primarily, to determine the association between the clinical severity of primary varicose veins and different reflux patterns in an anatomic and haemodynamic clinical study using duplex ultrasonography (DU). Secondly, to analyse the association of clinical severity with other aspects, such as risk factors for chronic venous insufficiency (CVI) and other concurrent diseases.
A total of 2036 limbs were evaluated using DU. Clinical status was characterized by the CEAP (clinical, aetiological, anatomical and pathological elements) classification. The degree of clinical severity was grouped into two categories, mild to moderate CVI (C1–C3) and severe CVI, characterized by the presence of skin changes (C4–C6). We analysed the association of the different reflux patterns with CEAP status.
Saphenofemoral junction (SFJ) reflux of the great saphenous vein (GSV) was associated with the most severe form of the disease (odds ratio [OR] = 2.96; confidence interval [CI] 95%: 2.2–3.8), whereas competent SFJ of the GSV with reflux from proximal veins (OR = 2; CI 95%: 1.4
Anatomical and haemodynamic studies by DU are postulated as a useful diagnostic tool that allow, by identifying the pattern of venous reflux of varicose pathology, characterization of the probable association to CVI clinical severity.
The aim of the study is to report a case of a rare congenital anomaly of the venous system and to emphasize its clinical importance. We describe a case of aplasia of the right common and external iliac veins in a healthy seven-year-old boy who was referred for Doppler ultrasound examination for further evaluation of an abnormal varicosity in the suprapubic region. Colour Doppler ultrasound revealed a dilated, arch-shaped vein. Contrast-enhanced magnetic resonance angiography showed the absence of the right common iliac vein and external iliac vein. It also clearly demonstrated the aberrant venous structure, originating from the right common femoral vein and draining to the left common femoral vein. In conclusion, in our case, the patient's life was threatened because the aberrant venous connection crossing within subcutaneous fatty tissue was not protected from external trauma and possible abdominal surgical interventions. Additional attention should be given to avoid such injuries, which can cause significant haemorrhage.
Cartilaginous metaplasia of superficial veins was found in a 64-year-old woman who underwent surgery for varicose veins. At operation, some varicose veins of the medial thigh were semi-rigid and fibroelastic to the touch. Histology revealed that half the lumen was occupied by chondroid tissue. The other half was obliterated by fibrous tissue, typical of post-thrombotic involution. Possible causes of cartilaginous metaplasia are briefly discussed.
