Abstract
Saphenopopliteal junction classification has been developing, but still the precise knowledge of junction type is crucial for proper surgical treatment. We examined the saphenopopliteal junction by duplex venous scanning in 244 extremities in healthy volunteers (median age: 23.0 years, 83 females, 39 male) and performed a meta-analysis of 13 studies focusing on structural types of the junction. According to Schweighoffer's classification we distinguished 5 types of the junction and we subdivided type A according to Cavezzi's classification of gastrocnemial veins termination into two. We added type F (small saphenous vein-SSV terminates into popliteal vein-PV), described especially in cadaveric studies. In our study, the most frequent type was A1 (96 cases), followed by C (70), B (48), A2 (20), E (6), D (3) and F (0). The pooled prevalence estimate for types A + B + D + E was 54.7% (95% CI 40.9-69.6%) and for type C 24.4% (95% CI 19.3-29.5%), whereas in 17.1% (95% CI 6.3-27.9%) of cases, the SSV terminated in the PV with no cranial extension present. The knowledge of the saphenopopliteal junction and its variations prevalence can help clinicians to quickly identify the real type of the junction during routine examination. In mid-European population, the main type is A1 and worldwide type A.

Abstract
BACKGROUND The term Anterior Accessory of the Great Saphenous Vein suggest 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.

Anatomical considerations of the sural nerve in the distal leg: Side branch patterns and significance in nerve harvesting procedures. Ann Anat 2024; 254:152242. [PMID: 38458574 DOI: 10.1016/j.aanat.2024.152242] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 02/08/2024] [Accepted: 03/05/2024] [Indexed: 03/10/2024]
Abstract
BACKGROUND The sural nerve is a somatosensory nerve that provides sensation to the posterolateral aspect of the lower leg and the lateral part of the ankle and foot. Due to its location and anatomical properties, it is often used as an autologous nerve graft. However, the nerve harvest can be complicated by the presence of side branches. The objective of this study was to investigate the anatomy of the sural nerve and to map its side branches. This information can be used to predict the localization of separate incisions during the stair-step incisions technique for nerve harvest, thereby reducing the risk of complications. METHODS The study involved the dissection of 50 adult cadaveric legs (25 left and 25 right) obtained from 27 Central European cadavers. The focus of the dissection was to identify the sural nerve, small saphenous vein, and surrounding anatomical structures. Detailed measurements were taken on the side branches of the sural nerve, tributaries of the small saphenous vein, and their interrelationship. RESULTS The average number of sural nerve side branches in a single leg was 4.2±1.9. These side branches were categorized into six groups based on their location and course: mediodistal, medioproximal, lateroproximal, laterodistal, medial perpendicular, and lateral perpendicular. Specific patterns of combination of these side branches were also identified and described. The branching point of the sural nerve was found to be 5.8±2.7 cm proximal to the lateral malleolus, whereas the small saphenous vein branching point was located more distally, 4.5 ± 2.8 cm proximal to the lateral malleolus. The highest density of sural nerve side branches was found 2.1-6.0 cm above the lateral malleolus. CONCLUSION This study presents valuable data about the relationship between the sural nerve and the surrounding anatomical structures in the distal part of the leg, including the identification of its side branches and their relevance during nerve harvest procedures. On the basis of the most frequent locations of side branches, a three-incision-technique for nerve harvest is proposed.

Abstract
BACKGROUND chronic venous disease (CVD) is a common progressive disorder with incompetence of calf muscle pump due to weakness and ankle mobility abnormality is an important etiological factor in CVD, but the biomechanical properties of calf muscle pump are remain unknown. OBJECTIVES The purpose of the present study was to evaluate group differences between the biomechanical properties changes of the medial gastrocnemius muscle (GM) and its fascias in participants with CVD and healthy controls. METHODS In this case-control study, thirty patients with CVD in three equal groups (mild: C1 - C2, moderate: C3 - C4, severe: C5 - C6) and 20 healthy subjects in a control group participated. The medial GM and its fascias shear modulus (stiffness) were measured using a shear-wave sonoelastography in rest and active dorsiflexion positions of ankle joint. RESULTS The results of variance (ANOVA) analysis showed a significant difference in shear wave elastography (SWE) value between the groups for medial GM and its fascias at rest and active dorsiflexion of the ankle joint (P < 0.05). There was a statistically significant increase in SWE value of the medial GM and its fascias in moderate (c3-c4) and severe CVD groups (C5-C6) compared to the control and mild (C1-C2) CVD groups. A positive correlation was discovered between disease grades and the medial GM and its fascias SWE in patients with CVD ranging between r = 0.846 to 0.891; P < 0.001. CONCLUSION An alteration stiffness in calf myofascial pump as compared to control group indicated an impaired myofascial biomechanics. Calf myofascial SWE may be valuable information in the diagnosis and follow-up processes of patients with CVD.

Abstract
ZusammenfassungIn der Phlebologie ist die Varikose die häufigste Erkrankung. Dabei sind die V. saphena magna und V. saphena parva meist in die pathologische Rezirkulation involviert. Ihre Anatomie ist relativ konstant, bis auf Feinheiten im Mündungsbereich und Verlauf, die jedoch in einer Zeit, in der es verschiedene Techniken und Strategien zur Behandlung der Varikose gibt, mit ins Kalkül gezogen werden müssen. Somit kann man es erlauben, den Patienten den möglichst nebenwirkungsarmen Eingriff mit der geringsten Rezidivhäufigkeit anzubieten. Der Ultraschall ist heute der Goldstandard in der Untersuchung der Beinvenen; daher muss die Anatomie der Venen immer auch im Ultraschall verstanden werden. Der Artikel beleuchtet schematisch die Anatomie und ergänzt die Beschreibung mit typischen Schallbildern zur V. saphena magna und parva.

Abstract
ZusammenfassungIn Giacominis Erstbeschreibung (1873) wurde über eine Vene berichtet, die über die Fossa poplitea zum dorsalen Oberschenkel (ohne in die V. poplitea einzumünden) weiter nach medial zieht, um in die V. saphena magna zu münden. Seither wurden zahlreiche weitere Mündungstypen (auch mit Einmündung in die V. poplitea) publiziert. Im klinischen Alltag erfährt diese Vene hingegen nur wenig Beachtung. Die Wahrscheinlichkeit, eine Insuffizienz der V. giacomini nachzuweisen, ist v. a. bei simultanem Vorliegen einer insuffizienten V. saphena parva um das knapp 12-Fache erhöht. Man unterscheidet 2 Refluxtypen der V. giacomini. Beim retrograden Reflux gelangt venöses Blut über die V. saphena magna, die Beckenvenen oder die Perforansvenen des Oberschenkels in die V. saphena parva. Beim wesentlich selteneren anterograden Reflux kommt es zu einem paradoxen (aufsteigenden) Reflux in der V. giacomini während der muskulären Diastole. Eine ausschließlich V.-saphena-fokussierte chirurgische Therapie ohne Berücksichtigung der Refluxtypen kann möglicherweise in einer Überbehandlung des Patienten enden und sollte im Zeitalter der therapeutischen Vielfalt und eines möglichst venenerhaltenden Vorgehens vermieden werden.Aufgrund der anatomischen Enge der Fossa poplitea und der in der Vergangenheit zunehmend an Beliebtheit gewonnenen endoluminal-thermischen Verfahren ist die Kenntnis der topografischen Anatomie insbesondere zur Vermeidung von neurologischen Komplikationen von essenzieller Bedeutung.

Abstract
Chronic venous insufficiency (CVI) of the lower extremities manifests itself in various clinical spectrums, ranging from asymptomatic but cosmetic problems to severe symptoms, such as venous ulcer. CVI is a relatively common medical problem but is often overlooked by healthcare providers because of an underappreciation of the magnitude and impact of the problem, as well as incomplete recognition of the various presenting manifestations of primary and secondary venous disorders. The prevalence of CVI in South Korea is expected to increase, given the possible underdiagnoses of CVI, the increase in obesity and an aging population. This article reviews the pathophysiology of CVI of the lower extremities and highlights the role of duplex ultrasound in its diagnosis and radiofrequency ablation, and iliac vein stenting in its management.

Abstract
Venous incompetence in the lower extremity is a common clinical problem. Basic understanding of venous anatomy, pathophysiologic mechanisms of venous reflux is essential for choosing the appropriate treatment strategy. The complex interplay of venous pressure, abdominal pressure, venous valvular function and gravitational force determine the venous incompetence. This review is intended to provide a succinct review of the pathophysiology of venous incompetence and the current role of imaging in its management.

Abstract
Advances in diagnosis and in endovascular and surgical treatments of both acute and chronic venous diseases have focused attention on several, previously clinically less important, details of venous anatomy. The time has come to standardize venous nomenclature so that general practitioners and specialists in the United States and abroad speak the same language. There is a need to adopt a universal terminology for the saphenous veins, to avoid the myriad of eponyms of perforators and, most importantly, to omit once and for all, the term “superficial” femoral vein when talking about a deep vein of the thigh. New anatomic names, such as the saphenous fascia and saphenous subcompartment, have to gain better recognition. To achieve the desired consensus on venous nomenclature, an international meeting was held in Rome, Italy, in 2001, under the auspices of the International Union of Phlebology. In this review on venous anatomy, we describe the most important previously published clinical recommendations from this conference, and suggest modifications based on their clinical experience using the new terminology.

Abstract
INTRODUCTION Superficial veins in the upper arm differ according to their relationship to the superficial fascia. We investigated the echographic landmark of the cephalic vein (CV) to correctly distinguish it from the collateral accessory vein (CAV) before hemodialysis angioaccess creation. MATERIALS AND METHOD Twenty consecutive patients were evaluated by ultrasonographic scan. The echographic features of CV and CAV together with their relationship were described. RESULTS Ninety-five percent of patients presented both CV and CAV (75% CAV laterally located, 25% medially located). CV and CAV diameters were 2.9 (±0.65) and 2.0 (±0.70), respectively. CONCLUSIONS CV differs from CAV for its anatomic location at forearm. Such a difference is clearly evident under ultrasound examination, despite any recommendation in ultrasound guidelines. Whether the exclusive use of CV for angioaccess creation can lead to a better outcome will be ascertained by further studies.

Abstract
The aim of this paper is to describe the anatomical relations of the small saphenous vein (SSV) in order to define the high-risk zones for the treatment of chronic venous disease. The SSV runs in the saphenous compartment demarcated by two fascia layers: a muscular fascia and a membranous layer of subcutaneous tissue. The clinician should be keenly aware of the anatomical pitfalls related to the close proximity of nerves to the SSV in order to avoid their injury: At the ankle, the origin of the SSV is often plexiform, located deep below the fascia, and the nerve is really stuck to the vein. The apex of the calf is an area of high risk due to the confluence of nerves which perforate the aponeurosis. Moreover, the possible existence of a 'short saphenous artery' which poses a high risk for injection of a sclerosing agent due to a highly variable disposition of this artery surrounding the SSV trunk. For this reason, procedures under echo guidance in this area are mandatory. The popliteal fossa is probably a higher risk zone due to the vicinity of the nerves: the small saphenous arch is close to the tibial nerve, or sometimes the nerve of the medial head of the gastrocnemius muscle. In conclusion, before foam injection or surgery, a triple mapping of the small saphenous territory is mandatory: venous haemodynamical mapping verifying the anatomy that is highly variable, nerve mapping to avoid trauma of the nerves and arterial mapping. This anatomical study will help to define the main high-risk zones.

Abstract
BACKGROUND Thermal damage to peripheral nerves is a known complication of endovenous thermal ablation (EVA) of the small saphenous vein (SSV). Therefore, the main objective of this anatomic study was to define a safe zone in the lower leg where EVA of the SSV can be performed safely. METHODS The anatomy of the SSV and adjacent nerves was studied in 20 embalmed human specimens. The absolute distances between the SSV and the sural nerve (SN) (closest/nearest branch) were measured over the complete length of the leg (>120 data points per leg), and the presence of the interlaying deep fascia was mapped. The distance between the SSV and the tibial nerve (TN) and the common peroneal nerve was assessed. A new analysis method, computer-assisted surgical anatomy mapping, was used to visualize the gathered data. RESULTS The distance between the SSV and the SN was highly variable. In the proximal one-third of the lower leg, the distance between the vein and the nerve was <5 mm in 70% of the legs. In 95%, the deep fascia was present between the SSV and the SN. In the distal two-thirds of the lower leg, the distance between the vein and the nerve was <5 mm in 90% of the legs. The deep fascia was present between both structures in 15%. In 19 legs, the SN partially ran beneath the deep fascia. In the saphenopopliteal region, the average shortest distance between the SSV and the TN was 4.4 mm. In 20%, the distance was <1 mm. The average, shortest distance between the SSV and the common peroneal nerve was 14.2 mm. The distance was <1 mm in one leg. CONCLUSIONS At the saphenopopliteal region, the TN is at risk during EVA. In the distal two-thirds of the lower leg, the SN is at risk for (thermal) damage due to the small distance to the SSV and the absence of the deep fascia between both structures. The proximal one-third of the lower leg is the optimal region for EVA of the SSV to avoid nerve damage; the fascia between the SSV and the SN is a natural barrier in this region that could preclude (thermal) damage to the nerve.

Abstract
Background Although fascial bands within the subcutaneous (SQ) layer are commonly seen in ultrasound images, little is known about their functional role, much less their structural characteristics. This study's objective is to describe the morphological features of SQ fascial bands and to systematically evaluate the bands using image analyses tools and morphometric measures. Methods In 28 healthy volunteers, ultrasound images were obtained at three body locations: the lateral aspect of the upper arm, medial aspect of the thigh and posterior aspect of lower leg. Using image analytical techniques, the total SQ band area, fascial band number, fascial band thickness, and SQ zone (layer) thickness were determined. In addition, the SQ spatial coherence was calculated based on the eigenvalues associated with the largest and smallest eigenvectors of the images. Results Fascial bands at these sites were contiguous with the dermis and the epimysium forming an interconnected network within the subcutaneous tissue. Subcutaneous blood vessels were also frequently encased by these fascial bands. The total SQ fascial band area was greater at the thigh and calf compared to the arm and was unrelated to SQ layer (zone) thickness. The thigh was associated with highest average number of fascial bands while calf was associated with the greatest average fascial band thickness. Across body regions, greater SQ zone thickness was associated with thinner fascial bands. SQ coherence was significantly associated with SQ zone thickness and body location (calf with statistically greater coherence compared to arm). Conclusion Fascial bands are structural bridges that mechanically link the skin, subcutaneous layer, and deeper muscle layers. This cohesive network also encases subcutaneous vessels and may indirectly mediate blood flow. The quantity and morphological characteristics of the SQ fascial band may reflect the composite mechanical forces experienced by the body part.

Abstract
Duplex ultrasonography (DUS) is an essential part of the evaluation of patients with most forms of superficial venous insufficiency. DUS has also become an important tool in directing and assessing the results of a variety of minimally invasive treatments of this disease. In this article, we review the salient aspects of performing an adequate DUS evaluation and the utility of this technique in guiding treatment.

Abstract
OBJECTIVES Short saphenous vein (SSV) surgery carries a high risk of failure to identify the saphenopopliteal junction (SPJ). We assessed the impact of surgical expertise on anatomical outcome from SSV surgery and the role of preoperative duplex SPJ marking in improving outcome for vascular and non-vascular specialists. METHODS A retrospective analysis identified patients (30 limbs) who had undergone SSV surgery. These were recalled for duplex scanning of the SPJ. In a prospective study, 187 limbs had preoperative duplex marking of SPJ and postoperative duplex to assess outcome. Grade of operating surgeon was recorded in both retrospective and prospective analysis. RESULTS In both retrospective and prospective analysis, vascular specialists were significantly more likely than non-vascular specialists to correctly identify the SPJ (P < 0.0001). Preoperative SPJ marking did not improve outcome for the vascular specialist or the non-vascular specialist. CONCLUSION Preoperative SPJ marking is no substitute for surgical expertise. Competence in SSV surgery should be assessed prior to surgeons proceeding to independent practice.

Abstract
The phlebology in the area of lower limbs is the only medical field in which the terminological needs of clinicians were met. Ten years ago, the latest revision of the Latin anatomical nomenclature, Terminologia Anatomica (TA), was issued. But almost none of the chapters reflected the clinicians' need to be a relevant theoretical base for correct diagnostics and appropriate treatment. In 2001, during the 14th World Congress of the International Union of Phlebology, a consensus document (under the auspices of Federative International Committee on Anatomical Terminology and International Federation of Associations of Anatomists) was laid to expand the nomenclature of the lower extremity venous system. Some terms have been changed and several new have been added, corresponding to their clinical significance and anatomical positions. Sixteen new terms have been added in both Latin and English languages in the chapter concerning the superficial veins of the lower limb. This consensus document will be incorporated into the next version of the TA. The international anatomical nomenclature serves as a communication base for research, diagnostic, therapy and information exchange in phlebological sciences.

Abstract
To assess outcomes after endovenous laser ablation (EVLA) of the small saphenous vein (SSV). Retrospective review was performed of all consecutive EVLA procedures performed over a 39-month period at three neighboring vein practices for symptomatic, duplex ultrasound-proven incompetence of the SSV. EVLA was performed under ultrasound guidance with an 810- or 980-nm diode laser in continuous mode using the pullback method while sparing the deep, most cephalad segment of the SSV near the saphenopopliteal junction. Follow-up after EVLA included patient symptoms, physical examination, and duplex ultrasound. Pretreatment variables were similar across all three practices. EVLA was performed to treat 67 incompetent SSVs in 63 patients (86% women; mean age and 95% confidence interval, 50 +/- 3 years; range, 20-82 years). Average energy delivered was 92 J/cm. Immediate technical success and occlusion of the treated vein at 1-2 weeks was 100%. Imaging follow-up length was 243 +/- 65 days (range, 3-893 days). Clinical follow-up (243 +/- 66 days) showed symptomatic improvement in 66 (99%) of 67 patients; one patient had recanalization with recurrent reflux by ultrasound (2%). Complications included one case of paresthesias lasting beyond 1 month of follow-up (2%) and three cases of superficial phlebitis (4%), but no deep vein thrombosis, skin burns, or other complications. Although ablation involved only the superficial portion of the SSV and spared its deep segment in the popliteal fossa, SSV occlusion typically extended up to the saphenopopliteal junction or to a gastrocnemial collateral, without popliteal vein involvement. EVLA of the SSV is safe and effective when the saphenopopliteal junction and popliteal fossa are avoided. This approach may help reduce the risk of paresthesias or other complications while maintaining low recanalization rates.

Abstract
A extensão cranial da veia safena parva se destaca pelas inúmeras variações anatômicas e diferentes padrões de fluxo que podem ser observados, descritos em trabalhos envolvendo dissecções pós-morte ou cirúrgicas, flebografias e Doppler, que denotam a formação embriológica mais precoce e complexa em relação à safena magna. A observação de um tipo específico de extensão cranial da safena parva onde o sentido das valvas é contrário ao habitualmente observado foi primeiramente caracterizada por Carlo Giacomini, sendo o fluxo caudal nesses casos de aspecto normal sem sinal de incompetência valvar. Este artigo demonstra os padrões anatômicos e de fluxo que podem ser caracterizados na veia safena parva, contribuindo para que aspectos normais do seu fluxo não sejam confundidos com incompetência valvar.

Abstract
PURPOSE To evaluate the potential of MRI to investigate the mechanical effects of compression stockings on the veins of the lower limb. MATERIALS AND METHODS The right calves of eight healthy volunteers were imaged in the prone position, with and without the presence of a compression stocking. Cross-sectional areas of all peroneal and posterior tibial veins, both saphenous veins, and any sufficiently large superficial veins were segmented in all subjects at mid-calf level in both cases. Variation in cross-sectional area along the axis of the great saphenous vein and a peroneal vein was also examined in three subjects. RESULTS The mean cross-sectional area reduction was found to be greater in the deep veins (64%) than in the superficial veins (39%). Deep-vein cross-sections were generally elliptical, while superficial veins were approximately circular. Significant axial fluctuations were found in the cross-sectional areas. CONCLUSION MRI offers a precise source of data on the mechanical effects of lower-limb compression. Ultrasound (US) may be more cost-effective, but the data acquired are less comprehensive. Future biomechanical studies of lower-limb compression should make use of MRI.

Abstract
BACKGROUND Primary varicose veins are commonly considered a progressive disease starting from the saphenous junctions and extending to tributaries in a retrograde fashion along the saphenous trunks. This theory has been criticized by studies indicating different patterns of development and progression of varicose veins. To contribute to the understanding of the pathogenesis of the disease, the anatomy of the venous bed was comparatively evaluated by duplex sonography in patients with varicose veins with a marked difference in age. METHODS The study included 100 varicose limbs in 82 patients aged < 30 years and 238 limbs in 183 patients aged > 60 years. Veins were designated as saphenous veins (SVs), tributaries of the SVs (STVs), and veins not connected with the SVs (NSVs). Four main anatomic patterns were comparatively evaluated: (1) varicose changes only along SVs, (2) varicose changes along SVs and STVs, (3) varicose changes only in STVs, and (4) varicose changes only in NSVs. RESULTS SVs were normal in 44% of varicose limbs. In most limbs from young subjects, varicose changes afflicted only SVTs (25%) and NSVs (36%). Varicose SVs were more frequent in the older group (62%) than in younger one (39%) owing to a higher prevalence of limbs with combined SV and STV varicosities (respectively, 59% and 37%). In the older group, varicosities in the STVs were more frequently observed in association with incompetence of the SV trunks. CONCLUSION The frequent occurrence of normal SVs in varicose limbs of all patients does not support the crucial role commonly credited to SVs in the pathogenesis of primary varicosities. Moreover, the SV trunks were normal in most varicose limbs from young patients. These findings suggest that varicose disease may progressively extend in an antegrade fashion, spreading from the STVs to the SVs. This hypothesis suggests that the saphenous trunks could be spared in the treatment of a relevant number of varicose legs. Prospective longitudinal studies with serial duplex evaluations of large series of extremities are necessary to confirm this hypothesis.

Abstract
A discrete membranous layer, "stratum membranosum", in human subcutaneous tissue is classically described as confined to the lower anterior abdominal wall and perineum and referred to as Scarpa's and Colles' fasciae, respectively. Evidence for its existence elsewhere in the body is scanty and therefore the present study was undertaken. Dissection of six embalmed adult cadavers, along with ultrasound imaging on four living subjects, were carried out to determine the existence, topography, and thickness of the membranous layer of superficial fascia in different regions of the body. In all six cadavers, a continuous layer of fibrous membrane in the superficial fascia was found consistently in all the dissected regions of the body and was also confirmed by ultrasonography. The arrangement and thickness of this membranous layer varied according to body region, body surface, and gender. It was thicker in the lower than in the upper extremity, on the posterior than anterior aspect of the body, and in females than in males. The mean thickness of the membranous layer ranged from 39 to 189 mum, being thickest in the leg and thinnest over the dorsum of the hand. The membranous layer was observed to have two or even three components in regions such as the breast, back, thigh, and arm and was seen to split, forming special compartments around subcutaneous major veins of upper and lower extremities, with fibrous septa extending to attach to the vessel wall. Functionally, the membranous superficial fascia may play a role in the integrity of the skin and support for subcutaneous structures particularly veins, by ensuring their patency. Understanding the topographic anatomy of this fascial layer may help explain body-contour deformities and provide the anatomic basis for surgical correction.

Abstract
OBJECTIVES Duplex ultrasound investigation has become the reference standard in assessing the morphology and haemodynamics of the lower limb veins. The project described in this paper was an initiative of the Union Internationale de Phlébologie (UIP), The aim was to obtain a consensus of international experts on the methodology to be used for assessment of anatomy of superficial and perforating veins in the lower limb by ultrasound imaging. DESIGN Consensus conference leading to a consensus document. METHODS The authors performed a systematic review of the published literature on duplex anatomy of the superficial and perforating veins of the lower limbs; afterwards they invited a group of experts from a wide range of countries to participate in this project. Electronic submissions from the authors and the experts (text and images) were made available to all participants via the UIP website. The authors prepared a draft document for discussion at the UIP Chapter meeting held in San Diego, USA in August 2003. Following this meeting a revised manuscript was circulated to all participants and further comments were received by the authors and included in subsequent versions of the manuscript. Eventually, all participants agreed the final version of the paper. RESULTS The experts have made detailed recommendations concerning the methods to be used for duplex ultrasound examination as well as the interpretation of images and measurements obtained. This document provides a detailed methodology for complete ultrasound assessment of the anatomy of the superficial and perforating veins in the lower limbs. CONCLUSIONS The authors and a large group of experts have agreed a methodology for the investigation of the lower limbs venous system by duplex ultrasonography, with specific reference to the anatomy of the main superficial veins and perforators of the lower limbs in healthy and varicose subjects.

Abstract
OBJECTIVES Primitive narrowing of great saphenous vein segments (saphenous hypoplasia) has been described in healthy limbs. The aim of the present study was to detect great saphenous vein segmental hypoplasia in limbs with varicose veins and to evaluate the local anatomical and haemodynamic patterns. MATERIALS AND METHODS The incidence of saphenous hypoplasia and the local haemodynamic rearrangement were evaluated by duplex ultrasonography in 676 normal limbs and in 320 limbs with varicose veins. RESULTS Segmental hypoplasia was demonstrated in 84 normal limbs and in 79 limbs with saphenous reflux. In the latter, the retrograde flow leaves the GSV at the proximal end of the hypoplastic segment to feed tributary veins. CONCLUSIONS Saphenous hypoplasia occurs in varicose limbs more frequently than in healthy ones (p= >0.001). It greatly influences the path of the reflux and the anatomy of the varicose veins. GSV segmental hypoplasia can be detected preoperatively by duplex ultrasonography. Its occurrence may influence surgical management for two main reasons: in about 68% of varicose limbs with segmental hypoplasia, the distal GSV is competent. If the distal GSV is varicose, its size and flow direction is normalised by treating the accessory vein that bypasses the hypoplastic segment.

Abstract
OBJECTIVE Coursing the posterior thigh as a tributary or trunk projection of the small saphenous vein (SSV), the Giacomini vein's clinical significance in chronic venous disease (CVD) remains undetermined. This cross-sectional controlled study examined the prevalence, anatomy, competency status, and clinical significance of the Giacomini vein across the clinical spectrum of CVD in relation to the SSV termination. METHODS One hundred eighty-nine consecutive subjects (301 limbs) with suspected CVD (109 men, 80 women; age, 18-87 years [median, 61 years]) underwent examination, clinical class (CEAP) stratification, and duplex ultrasound determination of the sites and extent of reflux >0.5 sec) and Giacomini vein's anatomy. RESULTS A Giacomini vein was found in 70.4% of limbs (212 of 301; 95% confidence interval, 65%-75.6%). Extent, pattern, and sites of reflux in all named superficial and deep veins were evenly distributed in limbs with and without a Giacomini vein; perforator vein incompetence in thigh and calf was also balanced (all, P > .2). Giacomini vein had no effect ( P > .2) on SSV termination anatomy, displaying a similar prevalence in classes C(0-6) . In 212 limbs, either as a tributary or trunk projection of the SSV, the Giacomini vein ascended subfascially (n = 210) to the lower (8%; n = 17), middle (47.6%; n = 101), or upper (44.3%; n = 94) thigh, and terminated at the deep system (45.3%; n = 96) and/or perforated the fascia (64.2%; n = 136), to join the superficial system. Giacomini vein morphology was not affected by the SSV termination anatomy and CEAP clinical class. Incompetence was detected less often (P < .001) in the Giacomini vein (4.7%; n = 10 of 212) than in the saphenous trunks cumulatively (53.3%; n = 113 of 212). Yet the odds ratio of Giacomini incompetence was 11.94 (7 of 33 over 3 of 169) in the presence of SSV reflux, and 11.67 (6 of 23 over 4 of 179) when both the great saphenous vein (proximal, proximal plus distal) and SSV were incompetent. CONCLUSION Found in more than two thirds of limbs, the Giacomini vein has a complex anatomy that is linked vastly to the deep or superficial veins of the posteromedial thigh, but is unaffected by the anatomy of SSV termination and CEAP clinical class. Its presence proved insignificant to the extent, pattern, sites, and clinical severity of venous incompetence, yet the Giacomini vein was far less often susceptible to reflux than the saphenous trunks were. Routine Giacomini vein investigation is not justified in view of these findings. Investigation could be considered selectively in limbs with SSV incompetence, with or without great saphenous vein incompetence, supported by the high odds of concomitant Giacomini vein reflux.

Abstract
The standard conduit in infrainguinal arterial bypass grafting, the great saphenous vein, is often unavailable. Arm and small saphenous veins are used as alternative conduits; yet both are deficient in length to accommodate femorocrural bypasses as a single conduit. In light of its high prevalence, the Giacomini vein harvested in continuity with the small saphenous vein may offer the latter extra length, promoting their combination into a single conduit able to meet the needs of infrainguinal reconstruction, particularly in lengthy infrainguinal bypass grafting. The Giacomini vein merits consideration when arterial reconstruction is performed in proximity to its anatomic course.

Abstract
BACKGROUND We frequently observe a tributary of the saphenous vein with the origin in the saphenous compartment of the medial aspect of the upper third of the leg. It runs transversally in the interfascial compartment toward the lateral aspect of the leg. Constantly it feeds by reflux varicose veins clinically visible in the paratibial region and/or in the lateral aspect of the leg. For the peculiarity of its anatomical shape as well as duplex appearance, we defined it as the "T" vein. OBJECTIVES To assess how frequently the "T" vein of the leg is involved in varicose networks. METHODS A total of 218 consecutive patients affected by primary varicose veins have been evaluated by the means of duplex scanning. We assessed both the presence of the above-mentioned tributary and the frequency of its hemodynamic involvement in the varicose network. RESULTS In 15 of 218 cases (7%) we demonstrated the above-mentioned tributary with an interfascial length ranging between 5 and 12 cm involved in varicose networks. CONCLUSIONS The anterior tributary of the saphenous vein of the anterolateral aspect of the leg is a neglected clinical entity, whose existence is important to know for the treatment of varicose veins of the lateral aspect of the leg.

Abstract
Physicians unfamiliar with venous insufficiency, particularly disorders of the superficial venous system, often underestimate the complexity of the problem and the importance of proper evaluation before initiating treatment. In addition to a directed history evaluation and physical examination, additional evaluation with use of a variety of noninvasive diagnostic instruments, including duplex ultrasound, may be necessary when determining the cause, severity, and best treatment options available for a particular patient. After such evaluation, the treating physician should have a precise map of the patient's pathways of venous insufficiency, including sources of reflux (eg, saphenofemoral junction, saphenopopliteal junction, perforators), tributaries, vein size, and vein morphology.

Abstract
BACKGROUND This was a retrospective assessment of the technical adequacy of saphenopopliteal disconnection (SPD). METHODS Patients scheduled for SPD underwent preoperative colour-coded duplex imaging to localize the saphenopopliteal junction (SPJ). Operations were conducted with the patients under general anaesthesia in the prone position with planned full popliteal fossa exposure. Patients were reimaged 6 weeks after operation. RESULTS Some 69 patients had surgery over 4 years; complete data were available for 59 (27 men and 32 women, median age 55 (range 27-78) years). There were eight staged bilateral procedures. Postoperative duplex scans identified 23 (39 per cent) with ideal results (incompetent SPJ successfully disconnected), 12 (20 per cent) with satisfactory results (incompetent SPJ disconnected successfully but persisting venous reflux in superficial veins), eight duplex failures (14 per cent) (previously identified incompetent SPJ persisted but was competent after operation) and 13 surgical failures (22 per cent) (incompetent SPJ completely missed during surgery). There were three major postoperative complications (5 per cent) (two deep vein thromboses and one popliteal vein injury) and one patient suffered a sural nerve palsy. CONCLUSION Despite preoperative duplex localization of the SPJ, SPD proved an unreliable technique in this series.

Abstract
Generally, when the origin of the word saphenous is discussed, most affirm that the term derives from the Greek word safaina, which means "evident." The ancient Greeks knew only the caudal portion of the vein, and neither the Greeks nor the Romans used the term saphena. In fact, the term first appeared in the writings of Avicenna. In contrast, the term saphenous is derived from the Arabic el safin, which means "hidden" or "concealed." Ancient Arabic physicians knew the anatomy of superficial veins of the human body and its extremities because they performed therapeutic bleeding. Arabic physicians phlebotomized the distal portion of the greater saphenous vein (GSV) at the ankle. Such phlebotomies were never performed on the proximal portions of the GSV because they were not superficial enough to be clearly evident. As a consequence, the proximal GSV was called el safin, or "the concealed." The modern reader will recognize that based on duplex examination, the GSV is correctly identified on the basis of its deep position with the superficial fascia covering it. This information may be useful in modern saphenous vein surgery in identifying the proximal portion of the GSV.
