Objective: to describe the possible types of the interrelations of the small saphenous vein and popliteal vein within the area of the popliteal fossa, as well as to study the distribution of the types among patients of both the genders and different somatotypes.Material and methods. 163 patients (326 extremities) of both the genders without signs of vascular pathology were examined by the method of duplex ultrasound scanning. According to Chernorutsky`s classification, the patients were divided into three groups: dolihomorphs, mesomorphs, brachymorphs. The percentage of different types of the topography of the small saphenous vein was calculated among the examined patients.Results. The term “saphenopopliteal pattern” has been introduced to characterize the anatomical interrelation of the small saphenous vein and popliteal vein within the area of the popliteal fossa. Five basic saphenopopliteal patterns were described including rare ones when the small saphenous vein opens into the gastrocnemius veins. It has been found that the patterns with the saphenopopliteal junction prevail (65.6 %), and in 28.3 % cases the small saphenous vein did not have any connection with the popliteal vein. The gender factor does not have any effect on the pattern type (р = 0.311) but the somatotype factor does (р = 0.038). It has also been determined that there is no direct connection between the small saphenous vein and popliteal vein in one thirds cases in the dolihomorphic and mesomorphic patients (34.5 % and 35 %, respectively), whereas the saphenopopliteal junction develops in 85.7 % cases in the brachymorphic patients.Conclusion. The proposed classification of the types of the topography of the small saphenous vein within the area of the popliteal fossa could be applied for the evaluation of the venous beds of the lower extremities by the method of duplex ultrasound scanning.

Objective: To use duplex ultrasound scanning to compare limbs with recurrent and primary varicose veins and to identify connections between deep veins and recurrences. Setting: A non-invasive vascular laboratory in Melbourne, Australia. Patients: A study of 779 limbs with recurrent varicose veins previously treated by ligation or stripping of the long saphenous vein and 1521 limbs with primary varicose veins. Main outcome measures: Connections between deep veins and recurrent varices, reflux in superficial and deep veins, and outward flow in perforators as demonstrated by duplex ultrasonography. Results: Recurrence was due to reflux in the long saphenous territory in 71.8%, short saphenous reflux alone in 14.7% or outward flow in calf perforators without saphenous reflux in 5.2%, while no source was detected in 8.3%. Limbs with recurrent veins in the long saphenous territory were compared with limbs with primary varicose veins; there was more frequent outward flow in thigh perforators (25.2% vs. 16.2%) but no difference for deep reflux (20.7% vs. 17.5%) or outward flow in calf perforators (56.8% vs. 53.1%). The source for recurrence in the long saphenous territory was from a single large connection in the groin in 46.3%, multiple smaller proximal connections in a further 46.3%, or thigh perforators in 7.4%. The destination was to an intact long saphenous vein in 33.7%, major tributaries in 28.7% or to other varices in 37.6%. Limbs known to have been treated by long saphenous ligation alone were compared with those known to be treated by long saphenous ligation and stripping; the source was more likely to be from a single large vein in the groin (60.3% vs. 39.9%) and the destination was more likely to be an intact long saphenous vein or major tributary (75.0% vs. 55.2%). Conclusions: Duplex ultrasound scanning detected the source of recurrent varicose veins in over 90% of patients and demonstrated whether there were single large or multiple smaller connections in the veins affected, and this helps to select the most appropriate treatment. Recurrence after stripping the long saphenous vein was more likely to be due to multiple small connections passing to scattered varices and this may allow more simple treatment by injection sclerotherapy rather than repeat surgery.

Maximum pressure head rises, which result from total closure of the valve from an initially fully open position, are calculated and plotted for the valve end and for the midpoint of a simple pipeline. Uniform, equal-percentage, optimum, and parabolic closure arrangements are analysed. Basic parameters such as pipeline constant, relative closure time, and pipe wall friction are considered with closures from full valve opening only. The results of this paper can be used to draw the maximum hydraulic grade line along the pipe with good accuracy for the closure arrangements considered. It is found that the equal-percentage closure arrangement yields consistently less pressure head rise than does the parabolic closure arrangement. Further, the optimum closure arrangement yields consistently less head rise than the equal-percentage one. Uniform closure produces pressure head rise that usually lies between those produced by the parabolic and the equal-percentage closure arrangements, except for the range of low pressure head rise combined with low or zero friction, where the rise due to uniform closure approaches that produced by optimum closure.

Objectives The purpose of this study was to determine the long-term efficacy, safety and rate of recurrence for varicose veins associated with great saphenous vein (GSV) reflux treated with ultrasound-guided foam sclerotherapy (UGFS). Methods A five-year prospective study was performed, recording the effect on the GSV and saphenofemoral junction (SFJ) diameters, and reflux in the superficial venous system over time. UGFS was the sole treatment modality used in all cases, and repeat UGFS was performed where indicated following serial annual ultrasound. Results No serious adverse outcomes were observed – specifically no thromboembolism, arterial injection, anaphylaxis or nerve damage. There was a 4% clinical recurrence rate after five years, with 100% patient acceptance of success. Serial annual duplex ultrasound demonstrated a significant reduction in GSV and SFJ diameters, maintained over time. There was ultrasound recurrence in 27% at 12 months, and in 64% at five years, including any incompetent trunkal or tributary reflux even 1 mm in diameter being recorded. Thirty percent had pure ultrasound recurrence, 17% new vessel reflux and 17% combined new and recurrent vessels on ultrasound. Of all, 16.5% required repeat UGFS treatment between 12 and 24 months, but less than 10% in subsequent years. The safety and clinical efficacy of UGFS for all clinical, aetiological, anatomical and pathological elements classes of GSV reflux was excellent. Conclusion The popularity of this outpatient technique with patients reflects ease of treatment, lower cost, lack of downtime and elimination of venous signs and symptoms. Patients accept that UGFS can be repeated readily if required for recurrence in this common chronic condition. The subclinical ultrasound evidence of recanalization or new vein incompetence needs to be considered in this light.

Duplex scanning is utilised by many departments in the investigation of suspected Deep Vein Thrombosis (DVT). NICE Guideline CG144 recommended repeat scanning for patients in whom the initial Wells score was ‘likely’ in the presence of a raised D-Dimer, following a normal first scan. Following implementation of this recommendation in our department there was a dramatic rise in the number of repeat scans being undertaken, all of which were negative for DVT. Introduction of an electronic message to the report, placing the onus back on the referring clinician to arrange repeat scan if deemed appropriate resulted in a fall in the number of scans being undertaken without impacting on patient outcome.
