“…The classification of GSV aplasia described by Seidel et al 12 was adopted for the color Doppler ultrasonography GSV examinations. This classification includes six types, as follows: Type I -exhibiting aplasia only in the thigh segment; Type II -aplasia in the leg segment; Type III -aplasia in the distal segment of the thigh and proximal segment of the leg; Type IV -vein in the saphenous compartment in the thigh and aplasia of the whole segment in the leg; Type V -vein in the saphenous compartment only in a short proximal segment in the thigh, outside of the compartment distally; and Type VI -vein with a short segment in the saphenous compartment only in the distal leg (Figures 1-3).…”

“…The presence of the wall of this compartment supplementing muscle contraction could modify the diameter of the vein and, consequently, modulate its blood flow, as happens in the deep vein system and, as such, the saphenous fascia would still preserve the GSV from excessive pathological dilation, providing mechanical protection. 12,20 Knowledge of the presence of segmental hypoplasia or aplasia of the GSV is important because if there is a reduction in diameter then there may be difficulty in advancing endoluminal instruments such as vein strippers and laser fibers or for thermoablation, and thermal damage to the skin may also occur because of the more superficial location of tributaries branches. Notwithstanding, abnormalities in anatomic course do not invalidate its use, as long as it has been evaluated in advance using color Doppler ultrasonography and an adequate diameter is preserved.…”

ResumoContextoHá diferenças individuais no diâmetro da veia safena magna (VSM) em membros normais e doentes; sendo possível a identificação dessas alterações pelo ecocolor Doppler.ObjetivoAvaliar a associação da aplasia segmentar da VSM com a presença de varizes e/ou insuficiência da mesma em membros inferiores, usando o ecocolor Doppler em pacientes com clínica de doença venosa crônica (DVC).Métodos1.408 pacientes com queixas compatíveis de DVC de membros inferiores, sendo 1.286 do sexo feminino, com idade entre 17 e 85 anos, examinados com ecocolor Doppler. Foram incluídos aqueles com classificação CEAP clínica C0 a C4. Pela avaliação clínica, a amostra foi distribuída em grupo A, pacientes com varizes, e grupo B, aqueles sem varizes. O ecocolor Doppler determinou se havia aplasia da VSM pela análise do seu trajeto no compartimento safeno e presença de veias varicosas nos diferentes sítios. Para estatística, foram considerados os testes Qui-quadrado ou Exato de Fisher e uma análise de resíduos em tabelas, com nível de significância de 5%.ResultadosNo grupo A houve 479 (83,9%) de VSM insuficientes, 169 (38,2%) com aplasia e 71 (80,7%) com insuficiência e aplasia associadas. No grupo B, houve 92 (16,1%) de VSM insuficientes, 273 (61,8%) com aplasia e 17 (19,3%) com insuficiência e aplasia associadas.ConclusãoA aplasia segmentar da VSM ocorre mais em membros inferiores que não apresentam varizes e/ou insuficiência da mesma, mas considerando-se a presença da associação de aplasia e insuficiência, houve maior incidência no grupo de membros que apresentavam varizes.

“…We have tried to classify the variants of hypoand aplastic GSV segment localization and extension according to the already known classifications. According to the classification of GSV aplasia described by Seidel A.C. et al (2012), there are 6 types of GSV aplasia: Type I -aplasia only in the thigh segment; Type II -aplasia in the tibial segment; Type III -aplasia in the distal segment of the thigh and the proximal segment of the tibia; Type IV -aplasia of the whole tibial segment; Type V -aplasia of the whole tibial segment and a significant part of the thigh segment without involving a short proximal segment; Type VI -aplasia of the entire vein without involving a short segment in the tibia [11,12]. According to the most common classification of GSV hypoplasia described by Caggiati A., Mendoza E. (2004), there are the following types of GSV hypoplasia: A -normally sized GSV segments join the suprafascial branch; B -distal GSV segment drains into the perforating vein; C -hypoplasia of the tibial part of the GSV; D -hypoplasia of the proximal part of the GSV which is shunted in the anterior accessory GSV [13].…”

The objective of the research was to improve the diagnostics and treatment of patients with primary varicose great saphenous veins by studying their frequency and systematizing the variants of localization and extension of great saphenous vein hypoplasia and aplasia in its trunk. Materials and Methods. The study included 560 patients with varicose veins of the lower limbs and pathological refluxes in different segments of the great saphenous vein. All the patients underwent triplex ultrasound scan of the lower limb venous system. Results. Among the patients with pathological reflux in a certain GSV segment, hypo- and aplasia of its segments were observed in 32.5% of the cases (95% CI 28.6-36.6%). Aplasia of this vein was observed twice as less frequently than hypoplasia (p<0.05). In 2.3% of the cases (95% CI 1.2-3.9%), hypoplasia of a certain GSV segment evolved to aplasia, or vice versa. It was found that the GSV trunk may have several hypo- or aplastic regions separated by its normal or varicose segment – bi-level hypo- or aplasia that was observed in 3.8% of the patients with hypo- or aplasia (95% CI 1.6-7.8%). In bi-level hypo- or aplasia, 2 hypoplastic regions were detected in 85.7% of the cases (95% CI 42.1-99.6%) and 2 aplastic regions were found in 14.3% of the cases (95% CI 0.4-57.9%). There were proposed to distinguish the following variants of GSV hypo- and aplasia: 1) simple: total, proximal, segmental and distal; 2) bi-level: proximal segmental, distal segmental and bi-segmental. In addition, for every dysplastic vein segment, the type of malformation should be indicated, namely hypoplasia, aplasia, or hypo/aplasia. Conclusions. The study conducted allowed assessing the relationship between the variants of GSV hypo- and aplastic segment localization and extension and different variations of pathological refluxes of the GSV in its trunk for further choice of surgical tactics.

“…An initial orientating prescan of the GSV along its course with the B-mode in a cross-section helps to get an overview regarding the presence, anatomy, diameter, and compressibility of the vein. A true GSV duplication is uncommon (up to 2 %) [52], whereas a segmental aplastic GSV, mostly in the distal section of the thigh and proximal calf, is found more often (17 %) [53]. In the latter case, the aplastic segment is often bridged by tributaries, which connect the proximal and distal portion of the GSV.…”

Summary:Lower extremities varicose veins are among the most frequent diseases in the general population. They can cause complaints with a deterioration of the quality of life and are associated with potentially threatening clinical conditions such as chronic venous ulceration, haemorrhage from ruptured varicose veins, and venous thromboembolism. An accurate diagnostic work-up is crucial to confi rm the presence and the extension of the venous problem, in order to obtain an optimal management of the condition. In the past years, great efforts have been made to reach an international consensus on the terminology, the symptomatology, the classifi cation, and the duplex ultrasound examination of lower extremities varicose veins. Mainly guided by these consensus documents, the present article describes the diagnostic work-up of lower extremities varicose veins, based on a careful medical history, physical examination, and duplex ultrasound examination.
