Assessment of Relationship between Saphenofemoral Junction Reflux and Great Saphenous Vein Diameter using Doppler Ultrasonography in Patients with Chronic Venous Disease: A Cross-sectional Study

Introduction: Chronic venous disease is a commonly occurring disease that includes a variety of pathological conditions like varicose veins, oedema, skin abnormalities, and ulceration, among which the most prevalent are the varicose veins. Doppler imaging is presently the first investigation for evaluating chronic venous disease. Aim: To investigate the relationship between Saphenofemoral Junction (SFJ) reflux and Great Saphenous Vein (GSV) diameter in patients with chronic venous disease and to determine the best cut-off value of GSV diameter in predicting reflux. Materials and Methods: The present cross-sectional study was conducted in the Department of Radiology, SRM Medical College and Hospital, Tamil Nadu, India, from December 2019 to June 2021 on 76 patients with chronic venous disease. The study was conducted on a GE Logic P9 ultrasound machine, the diameter of GSV was measured close to the SFJ, at the Proximal Thigh (PT); 15cm distal to the SFJ, and at the calf. The diameter of the GSV was compared with the presence of SFJ reflux. Similarly, Short Saphenous Vein (SSV) diameter was also measured posterior to the knee and was correlated with Saphenopopliteal Junction (SPJ) reflux. Chi-square and student t-tests were used for analysis with a cut-off value determined through Receiver Operating Characteristic (ROC) curve analysis. Results: The mean age of study participants was 51±15.85 years with age range of 19 years to 78 years. Of total, 42 (55.26%) had chronic venous insufficiency on the left side and 34 (44.74%) had on the right side. The mean GSV diameter at SFJ and at PT was higher in patients with SFJ incompetence and was statistically significant with a p-value of 0.001 and 0.002, respectively by t-test. Although the mean GSV diameter at calf was higher in patients with SFJ incompetence, it was statistically insignificant. The GSV diameter at the SFJ had the best cut-off value for predicting incompetence, with a mean diameter of 5.95 mm with 76.3% sensitivity and 76.3% specificity. The cut-off of SSV at the posterior knee for predicting SPJ incompetence was 4.6 mm which had a sensitivity of 72.7% and specificity of 88.7% and diagnostic accuracy of 86.84%. Conclusion: The GSV diameter at SFJ and PT help in predicting SFJ incompetence. The SSV diameter at SPJ aids in predicting SPJ incompetence.

Frequency of Sapheno-Femoral Junction and Sapheno-Popliteal Junction Incompetence on Duplex Ultrasonography in Patients with Varicose Veins

Objective: To determine frequency of sapheno-femoral junction (SFJ) and sapheno-popliteal junction (SPJ) incompetence on duplex ultrasonography in patients with varicose veins.Study Design: Cross-sectional study.Place and Duration of Study: Shaikh Khalifa Bin Zayed Al-Nahyan/Combined Military Hospital, Rawalakot, Azad Jammu & Kashmir, from Aug 2019 to Feb 2020.Methodology: A total of 70 patients were selected using non-probability, consecutive sampling. After ethical approval, informed consent and relevant history taking, duplex ultrasonography (DUS) was done in standing and supine positions in patients with varicose veins, fulfilling inclusion and exclusion criteria. Presence or absence of SFJ and SPJ incompetence was assessed.Results: Mean age was 41.99 ± 11.08 years with 36 (51.43%) patients between 36-50 years. Mean duration of disease was 6.33 ± 2.29 months while 47 (67.14%) patients had symptoms for more than 6 months at the time of presentation. Occupation wise, 40 (57.14%) patients were field workers while 30 (42.86%) were office and domestic workers. Isolated SFJ, SPJ and combined junction incompetence were found in 27 (38.57%), 20 (28.57%) and 23 (32.86%) patients respectively. Both SFJ and SPJ incompetence were more in obese patients (78.6% and 71.4% respectively) as compared to non-obese patients.
 Conclusion: Frequency of SFJ incompetence was more than SPJ incompetence on DUS. Obesity, male gender and prolonged motionless standing predispose to the development of varicose veins. Preventive measures and early diagnosis can decrease disease burden.

Randomized Clinical Trial of Endovenous Laser Ablation Versus Conventional Surgery for Small Saphenous Varicose Veins

No randomized clinical trial comparing treatment options for small saphenous vein (SSV) incompetence exists, and there is no clear evidence that this axis behaves the same as the great saphenous vein after treatment. This means that the existing literature base, centered on the treatment of great saphenous vein incompetence cannot simply be extrapolated to inform the management of SSV insufficiency. This trial compares the gold standard of conventional surgery and endovenous laser ablation (EVLA) in the management of SSV incompetence. Patients with unilateral, primary saphenopopliteal junction incompetence and SSV reflux were randomized equally into parallel groups receiving either surgery or EVLA. Patients were assessed at baseline and weeks 1, 6, 12, and 52. Outcomes included successful abolition of axial reflux on duplex, visual analog pain scores, recovery time, complication rates, Venous Clinical Severity Score, and quality of life profiling. A total of 106 patients were recruited and randomized to surgery (n = 53) or EVLA (n = 53). Abolition of SSV reflux was significantly higher after EVLA (96.2%) than surgery (71.7%) (P < 0.001). Postoperative pain was significantly lower after EVLA (P < 0.05), allowing an earlier return to work and normal function (P < 0.001). Minor sensory disturbance was significantly lower in the EVLA group (7.5%) than in surgery (26.4%) (P = 0.009). Both groups demonstrated similar improvements in Venous Clinical Severity Score and quality of life. EVLA produced the same clinical benefits as conventional surgery but was more effective in addressing the underlying pathophysiology and was associated with less periprocedural morbidity allowing a faster recovery.

Hemodynamic patterns of reflux in primary sapheno-popliteal junction incompetence

Duplex ultrasound investigation (DUI) has considerably improved the diagnosis of anatomical venous variations in the popliteal region: however, some pitfalls still remain concerning the hemodynamics of incompetent sapheno-popliteal junctions (SPJs). Aims of this study were to assess the prevalence rates of the hemodynamic patterns of reflux, either diastolic or systolic or both, in a large series of patients with SPJ incompetence, and to analyze the origin of the systolic components of the reflux. Four hundred and fiftythree patients, 83 males and 370 females, mean age 58.0 years&plusmn;SD 13.8 with primary SPJ incompetence (512 limbs) underwent preoperative DUI using the Paran&agrave; manoeuvre, a dynamic test able to develop systolic and diastolic pressure gradients through the reflex activation of muscle pumps. Of the 512 incompetent SPJs, 420 showed isolated diastolic reflux, 9 isolated systolic reflux and 83 systolic reflux followed by diastolic reflux. Altogether, 92 SPJs over 512 (18%) showed a systolic component of the reflux, which originated from the popliteal vein in 78 cases (15%) and from the gastrocnemius veins (GVs) in 14 cases (3%). In these latter cases, the short saphenous vein and one or more GVs showed a common trunk. Our findings show that the detection of a systolic component of the reflux in incompetent SPJs is not an uncommon event and suggest that treatment strategy should be differentiated according to the origin of the systolic reflux, given their different hemodynamic behavior.

Endovenous Laser Ablation in the Treatment of Small Saphenous Varicose Veins

The study was performed to evaluate the clinical and technical efficacy of endovenous laser ablation (EVLA) of small saphenous varicosities, particularly in relation to the site of endovenous access. Totally 59 patients with unilateral saphenopopliteal junction incompetence and small saphenous vein reflux underwent EVLA (810 nm, 14 W diode laser) with ambulatory phlebectomies. Small saphenous vein access was gained at the lowest site of truncal reflux. Patients were divided into 2 groups: access gained above mid-calf (AMC, n = 33) and below mid-calf (BMC, n = 26) levels. Outcomes included Venous Clinical Severity Scores (VCSS), Aberdeen Varicose Vein Questionnaire (AVVQ), patient satisfaction, complications, and recurrence rates. Both groups demonstrated significant improvement in VCSS, AVVQ, generic quality of life Short Form 36, and EuroQol scores (P < .05) up to 1 year. No differences were seen between AMC and BMC groups for complications (phlebitis: 2 [6%] and 1 [3.8%], P > .05; paresthesia: 2 [6%] and 5 [19%], P = .223) and recurrence (3 [9%] and 1 [3.8%], P = .623), respectively. The site of access in our study does not appear to influence complications specifically neural injury or recurrence rates.

980-nm laser therapy versus varicose vein surgery in racially diverse Penang, Malaysia

Chronic venous disorders are conditions of increasing prevalence in the developing world, and venous ulceration is the terminal sequel. Currently there are only limited data on all aspects of this from Southeast Asia. The aim of the present study was to assess differences in the demography and outcome between varicose vein surgery (VVS) and the relatively new endovenous laser therapy (EVT) in patients from Penang, Malaysia. A retrospective study was performed. Patients who presented to the outpatient clinic of the surgical department with saphenofemoral junction and/or saphenopopliteal junction incompetence associated with reflux of the great saphenous vein or small saphenous vein, respectively, underwent either surgery (1999-2004) or laser therapy (2004-2006). A single surgeon at a single institution performed all procedures. A total of 350 limbs were treated from 292 patients. Demographics, symptoms, outcomes and complications that arose in both groups were compared. There were significant improvements in pains, swelling, cramps and heaviness postoperatively (P < 0.001) in both groups. Deep venous thrombosis was present as a complication in the VVS group at 3.0%, but was absent altogether in the EVT group. Although both are highly effective procedures, laser therapy has become popular as an elective procedure with its minimally invasive nature, cosmesis, rapid recovery and other advantages. Surgery remains an important and very cost-effective procedure, especially in a developing society such as Penang.

A prospective evaluation of the outcome after small saphenous varicose vein surgery with one-year follow-up

The aim was to examine the effect of various surgical maneuvers during standard surgery for small saphenous varicose veins (SSV). This was a prospective cohort study of patients that underwent small saphenous varicose vein surgery. Two-hundred nineteen consecutive patients (234 legs) with isolated primary or recurrent small saphenous varicose veins undergoing surgery were enrolled in a multicenter study involving nine vascular centers in the United Kingdom. Operative technique was determined by individual surgeon preference; clinical and operative details, including the use of stripping, were recorded. Clinical examination (recurrence rates) and duplex imaging (superficial and deep incompetence) were evaluated at six weeks and one year after surgery. A total of 204 legs were reviewed at one year; 67 had small saphenous varicose vein stripping, 116 had saphenopopliteal junction (SPJ) disconnection only, and the remainder had miscellaneous procedures. The incidence of visible recurrent varicosities at one year was lower after SSV stripping (12 of 67, 18%) than after disconnection only (28 of 116, 24%), although this did not reach statistical significance. There was no significant difference in the rate of numbness at one year between those who had SSV stripping (20 of 71, 28%) and those who had disconnection only (38 of 134, 28%). The rate of SPJ incompetence detected by duplex at one year was significantly lower in patients who underwent SSV stripping (9 of 67, 13%) than in those who did not (37 of 115, 32%) (P < .01). Stripping of the SSV significantly reduced the rate of SPJ incompetence after one year without increasing the rate of complications.

Endovenous Laser Ablation (EVLA) of Great Saphenous Vein to Abolish “Paradoxical Reflux” in the Giacomini Vein: A Short Report

Reflux in the GSV due to sapheno-popliteal incompetence associated with ascending (paradoxical) reflux in the Giacomini vein is a rare but well described pattern of reflux. Treatment of this type of reflux is controversial and only surgical treatment has been described. We describe 2 patients in whom this type of reflux was successfully abolished following endovenous laser ablation (EVLA) of the GSV with the SPJ and Giacomini vein regaining competency. Paradoxical reflux in the Giacomini vein and SPJ is secondary to GSV incompetence which exerts a syphon effect. EVLA of the refluxing segment of GSV interrupts this effect and prevents the paradoxical reflux at the SPJ.

Whole-leg duplex mapping for varicose veins: Observations on patterns of reflux in recurrent and primary legs, with clinical correlation

Background: the variability of venous reflux patterns complicate the management of venous disease. Our study investigates specific variations in venous anatomy and patterns of reflux in varying clinical situations. Methods: prospective analysis of 464 legs in 355 patients was performed by complete duplex venous mapping of both primary and recurrent varicose veins. Hand Held Doppler (HHD) and Duplex Ultrasonography (Duplex US) observations in the popliteal fossa were compared in a subgroup of 89 patients with primary varicose veins. Distribution of venous system disease was correlated with clinical severity in a subgroup of 117 affected legs which was representative of the overall study group. Results: sapheno-femoral junction (SFJ) incompetence predominated in both primary and recurrent varicose veins. Only 21% of primary legs and 25% of recurrent legs had sapheno-popliteal junction (SPJ) incompetence. SPJ incompetence was present in only 42% of cases where reflux in the popliteal region on HHD had been demonstrated. A proportion of both primary and recurrent varicose veins had evidence of deep venous incompetence (DVI). Sixty-four percent of primary leg ulcer patients had superficial incompetence alone. In patients with recurrent varicosities and ulceration, 57% had SPJ incompetence, 64% multiple sites and 50% DVI. Conclusion: the complex variations of varicose vein anatomy and functional pathology in the lower limb are currently best assessed by complete whole-leg venous duplex mapping.Eur J Vasc Endovasc Surg 25, 267–275 (2003)

Variable venous anatomy of the popliteal fossa demonstrated by duplex scanning.

Location of the sapheno-popliteal junction (SPJ) is highly variable and therefore often difficult to identify correctly at operation. The anatomy is often complicated by associated pathology in the popliteal fossa, which makes clinical examination unreliable. The purpose of our study was to quantify this variability and record other concomitant pathology in patients with sapheno-popliteal junction incompetence. We retrospectively reviewed duplex scans of 544 patients with 638 legs showing SPJ incompetence, from a total of approximately 4000 patients attending our laboratory between August 1993 and August 1995. We found that 51% of sapheno-popliteal junctions were located within 2 cm above the popliteal skin crease and a further 36% within 4 cm, with the remaining situated anywhere between 4 and 10 cm above the popliteal skin crease. Additionally 18% of patients had either Giacomini or gastrocnemius vein incompetence in addition to SPJ incompetence, further complicating the clinical picture. When SPJ incompetence is suspected, duplex scanning identifies the exact location of the junction and other associated pathology in the popliteal fossa, and allows the position of the junction to be marked on the leg preoperatively.

The use of routine duplex scanning in the assessment of varicose veins.

Clinical assessment has been shown to compare poorly with results of hand-held Doppler examination or venography in the evaluation of varicose veins. Although the use of duplex scanning has been well described in the assessment of varicose veins, there are few data comparing clinical and Doppler assessment with results of duplex scans. A total of 188 patients were referred with varicose veins to a sole specialist vascular surgeon over a 1-year period. After clinical and Doppler assessment, all patients were referred for a duplex scan which was performed by a trained vascular technician. The results of the duplex scan were compared retrospectively with the clinical and Doppler findings. A total of 315 legs were assessed over this period, with 38.7% having recurrent disease and 31.4% having trophic skin changes or ulceration. On duplex scanning, 198 legs (62.9%) had saphenofemoral junction incompetence, 61 legs (19.4%) had saphenopopliteal junction incompetence, 94 legs (29.8%) had perforator incompetence and 24 legs (7.6%) had deep venous incompetence. The respective sensitivity of clinical and Doppler assessment at these sites was 71.2, 36.1, 43.6 and 29.2%. If patients who were felt to have sole saphenofemoral junction incompetence clinically were treated by high ligation, stripping to the knee and stab avulsions, 28.9% would have had sites of reflux untreated. Clinical and Doppler assessment is unreliable. Routine duplex scanning is likely to reduce recurrence by identifying sites of reflux with greater accuracy.
