Internal valvuloplasty combined with sleeve wrapping in the treatment of severe great saphenous vein insufficiency: A report of two cases.

BACKGROUND: Great saphenous vein (GSV) valve incompetence is one of the most common manifestations of chronic venous insufficiency (CVI) in the lower limbs. There have been no reported attempts to repair the valve prior to the appearance of varicose morphology. METHOD: We describe two cases. Before surgery, the male patient had obvious pigmentation in the ankle area, and the female patient had obvious pain and swelling in the lower limbs after prolonged standing. Neither patient has obvious varicose veins. After retrograde venography, both patients were found to have severe reflux of the GSV valves (Kinster IV). We performed internal valvuloplasty and sleeve wrapping in two patients. RESULTS: After surgery, both patients had a significant improvement in symptoms and no particular complaints. Vascular ultrasound also suggested a good outcome. CONCLUSION: This surgery is safe and feasible in the treatment of early GSV incompetence, with good short-term results; long-term results remain to be seen.

Diagnosis and Management of Pelvic Congestion Syndrome: Comprehensive Review.

BACKGROUND: Pelvic congestion syndrome (PCS) is a poorly understood condition that can be associated with chronic pelvic pain and could impact quality of life. The diagnosis is often made by exclusion of other causes of pelvic pain. OBJECTIVE: The purpose of our review was to provide an update on the etiology, anatomy, physiology, identification, and the therapeutic management of PCS. METHOD: We conducted a literature review involving publications from 2003 to 2024 in PubMed, Elsevier, MEDLINE, as well as manual searches of primary and review articles using keywords such as "pelvic veins", "embolization", "venography", "pelvic congestion syndrome", and "chronic pelvic pain". CONCLUSION: PCS remains poorly understood. Symptoms can be non-specific and difficult to distinguish from other diseases; yet it is an important cause of chronic pelvic pain in women. To date, there have been only a small number of randomized trials and high-level evidence is still lacking. OUTLOOK: We call for an increased awareness of PCS and additional clinical studies in a large number of patients.

Hypofractionated stereotactic radiosurgery for dural arteriovenous fistula in the superior sagittal sinus: case report and review of the literature.

Stereotactic radiosurgery (SRS) for dural arteriovenous fistula (dAVF) in the superior sagittal sinus (SSS) is not an established treatment because of relatively poor efficacy and a latency period for treatment effects. Hypofractionated SRS for these lesions has not yet been reported. A 65-year-old man presented with intermittent paraparesis. Brain magnetic resonance imaging (MRI) revealed acute infarction in the premotor and motor cortex of both frontal convexities. Cerebral angiography demonstrated extensive dAVF in the middle and posterior third SSS, associated with an occlusion in the middle third. Transfemoral arterial Onyx embolization was performed through the right middle meningeal arteries, and cerebral venous reflux (CVR) disappeared from the middle third of the SSS. However, the remnant dAVF in the posterior third of the SSS and CVR in the posterior parietal and occipital lobes remained. Novalis SRS was performed on remnant the dAVF with 35 Gy in 5 fractions. Seven months after Novalis SRS, symptoms improved and cortical engorged vessel gradually disappeared on brain MRI. The patient recovered completely at 22 months post-radiosurgery. SRS for dAVF in the SSS could provide an alternative treatment option. Hypofractionated SRS showed a good result in our case.

Early versus deferred endovenous sclerotherapy of superficial venous reflux in patients with venous ulceration.

This study aimed to compare early endovenous sclerotherapy with superficial venous reflux combined with compression therapy and deferred intervention in patients with venous leg ulcers (VLUs). A total of 80 patients with 80 VLUs treated at the Department of General Surgery, Shangjin Nanfu Hospital, Chengdu, China, between February 2022 and January 2023 were included in the study. The primary outcome was the time to ulcer healing from the date of compression therapy or endovenous sclerotherapy. Secondary outcome measures were the rate of ulcer healing at 6 months, the rate of ulcer recurrence at 6 months, and patient-reported health-related quality of life. A total of 54 patients received early intervention and 26 received deferred intervention. The patient and clinical characteristics at baseline were similar between the two treatment groups. The median time to ulcer healing was 1.5 months (95% confidence interval [CI], 1.3-1.7 months) in the early-intervention group and 3.5 months (95% CI, 2.9-4.1 months) in the deferred-intervention group. The time to ulcer healing was shorter in the early-intervention group than in the deferred-intervention group (p < 0.001). The rate of ulcer healing at 6 months was 94% in the early-intervention group and 92% in the deferred-intervention group. The rate of ulcer recurrence before the end of the 6-month follow-up period was 2% in the early-intervention group and 4% in the deferred-intervention group. In conclusion, early endovenous sclerotherapy for superficial venous reflux resulted in faster healing of VLUs than deferred endovenous sclerotherapy.

Near Infrared Fluorescence Imaging to Demonstrate Reflux in the Superficial Microvenous Network of the Leg.

OBJECTIVE: Reflux within the superficial microvenous network may play a critical role in the development of skin changes which can be associated with chronic venous insufficiency. This study aimed to determine if near infrared fluorescence (NIRF) imaging could be used to accurately determine superficial venous reflux in the leg. METHODS: A total of nine limbs were examined ex vivo from patients undergoing limb amputation for peripheral arterial disease. Cannulation of the distal great saphenous vein was used to sequentially perform Xray contrast enhanced venography, NIRF imaging, and venous corrosion casts. RESULTS: Fluorescence imaging visualised a range of different microvenous reflux patterns ex vivo, which were generally not evident by Xray venography but were consistent with retrograde resin vascular casts. These included both focal and diffuse regions of fluorescence within the skin and, consistent with previous observations, the vascular casts indicated that regions of venous reflux were typically associated with incompetent valves. CONCLUSION: The findings from this study suggest a potential method for investigating early stage superficial venous disease, prior to the appearance of visible signs of advanced venous disease, such as skin changes. However, further studies are required to confirm the in vivo clinical utility of these observations.

Foam sclerotherapy of great saphenous vein: The need for further improvement and ill-defined issues.

Foam sclerotherapy is considered an acceptable method to treat great saphenous vein (GSV) insufficiency, promoting occlusion of its trunk and eradicating reflux. Yet, certain technical points have not been standardized while issues regarding the ultrasonographic appearance of successful or acceptable GSV obliteration or the end-points of the method are not clearly defined. This article comments on the aforementioned using examples based on personal experience.

Radiofrequency ablation for markedly incompetent perforators versus compression therapy in the management of post-phelebtic venous ulcers: A randomized controlled trial.

BACKGROUND: Venus ulcers developed mainly due to reflux of incompetent venous valves in perforating veins. PATIENTS AND METHODS: In this randomized controlled trial, 119 patients recruited over two years, with post-phelebtic venous leg ulcers, were randomly assigned into one of two groups: either to receive radiofrequency ablation of markedly incompetent perforators (Group A, n = 62 patients) or to receive conventional compression therapy (Group B, n = 57 patients). Follow-up duration required for ulcer healing continued for 24 months post randomization. RESULTS: Statistically significant shorter time to healing (ulcer complete healing or satisfactory clinical improvement) between both groups (56 patients, 90.3% of cases in Group A versus 44 patients 77.2% of cases in Group B) over the follow-up period of 24 months was attained (p = 0.001). Also, significantly different ulcer recurrence was recorded between both groups, 8 patients (12.9%) in Group A versus 19 patients (33.3%) in Group B (p = 0.004). CONCLUSION: In absence of deep venous obstruction, the monopolar radiofrequency ablation for incompetent perforators is a feasible and effective method that surpasses the traditional compression protocol for incompetent perforator-induced venous ulcers in terms of time required for healing even in the presence of unresolved deep venous valvular reflux.

Comparison of the standardized Valsalva manoeuvre versus the cuff deflation method to elicit venous reflux.

Background: Two standardized methods to detect venous reflux, the Valsalva manoeuvre (VM) and the cuff deflation method (CM) are compared. Patients and methods: We included 72 patients with varicose veins (VV) and 106 patients with deep vein thrombosis (DVT). The proximal leg veins were examined. A survey was sent to the members of the Union of Vascular Societies to assess, which methods are used in the clinical practice. Results: In the VV-group the correlation coefficient (VM vs CM) for the reflux time (RT) amounted to 0.44 (p<0.0001) for the common femoral vein (CFV) and 0.4 for the femoral vein (FV) (p=0.0003). The sensitivity of the two tests in the VV group amounted to 87.5% for both methods in the CFV (p=0.4). The sensitivity for the FV amounted to 87.5% for the VM and 71.4% for the CM (p=0.4). In the DVT - group the correlation coefficient (VM vs CM) for RT amounted to 0.62 for the CFV (p<0.0001) and 0.77 for the FV (p<0.0001), as well as to 0.6 for the great saphenous vein (GSV) (p<0.0001). The sensitivity of the two tests amounted to 50.0% for the VM and 42.9% for the CM in the CFV (p=0.5). The sensitivity, if reflux was measured in the FV, amounted to 42.9% for the VM and 50.0% for the CM (p=0.5). 87.3% of the doctors who answered the survey use a non-standardized reflux measurement method. Conclusions: Both methods of reflux measurement (VM, CM) are comparable. Further studies have to address the issue, whether non standardized methods are as accurate as the standardized manoeuvres.

Preliminary Results of a New Illuminated Radiofrequency Ablation Catheter for the Treatment of Great Saphenous Vein Reflux Disease.

Introduction: In the current study, we present single surgeon experience of a new radiofrequency ablation system, the catheter, and the device. Patients and Methods: The new system, which comprises a generator and an intervally illuminated radiofrequency ablation catheter, was used for the treatment of 272 consecutive patients with chronic venous insufficiency of the great saphenous vein between November 2017 and October 2018. Mean age of the patients was 53.40 ± 11.91 years. Mean saphenous vein diameter was 8.51 ± 2.45 mm. Bilateral great saphenous vein reflux disease was present in 19% (51 cases) of the patients. At the end of the procedure, the closure of the great saphenous vein was confirmed with Doppler ultrasonography. Results: Procedures could be successfully performed in all, except 1 obese (BMI> 30 kg/m2) male patient. At the 3rd month, outpatient clinic follow-up control Doppler USG revealed successful ablation of the treated great saphenous vein in 260 patients (96%), whereas in 12 cases (4%), there was continuing reflux. The diameters of the saphenous veins in these patients ranged between 6.9 mm and 19.5 (mean: 10.68 ± 3.41) mm. Ten patients could be treated successfully with ablation with the same device controlled both at the interventional section as well as on the 3rd month outpatient clinic follow-up. The remaining patients underwent high ligation of the great saphenous vein. Paresthesia occurred in 1 patient and had been permanent. Hematoma occurred in a male patient and resolved spontaneously. Conclusion: Preliminary results of our new radiofrequency ablation device with illumination guidance for the treatment of great saphenous vein reflux disease indicated successful results with enhanced physician utilization, comfort, and reliability.

Histopathological study of JNK in venous wall of patients with chronic venous insufficiency related to osteogenesis process.

Chronic venous insufficiency (CVI) is one of the most common vascular pathologies worldwide. One of the risk factors for the development of CVI is aging, which is why it is related to senile changes. The main trigger of the changes that occur in the venous walls in CVI is blood flow reflux, which produces increased hydrostatic pressure, leading to valve incompetence. The cellular response is one of the fundamental processes in vascular diseases, causing the activation of cell signalling pathways such as c-Jun N-terminal kinase (JNK). Metabolic changes and calcifications occur in vascular pathology as a result of pathophysiological processes. The aim of this study was to determine the expression of JNK in venous disease and its relationship with the role played by the molecules involved in the osteogenic processes in venous tissue calcification. This was a cross-sectional study that analyzed the greater saphenous vein wall in 110 patients with (R) and without venous reflux (NR), classified according to age. Histopathological techniques were used and protein expression was analysed using immunohistochemistry techniques for JNK and markers of osteogenesis (RUNX2, osteocalcin (OCN), osteopontin (OPN)). Significantly increased JNK, RUNX2, OCN, OPN and pigment epithelium-derived factor (PEDF) protein expression and the presence of osseous metaplasia and amorphous calcification were observed in younger patients (<50 years) with venous reflux. This study shows for the first time the existence of an osteogenesis process related to the expression of JNK in the venous wall.

Interdisciplinary treatment of posterior fossa dural arteriovenous fistulas.

BACKGROUND: Posterior fossa dural arteriovenous fistulas (dAVFs) are rare vascular lesions with variable risk of hemorrhage, mostly depending on the pattern of the venous drainage. While endovascular embolization is the mainstay treatment for most dAVFs, some posterior fossa lesions require a multidisciplinary approach including surgery. The goal of our study was to examine the outcome of an interdisciplinary treatment for posterior fossa dAVFs. METHODS: A retrospective review of patients treated for posterior fossa dAVFs was conducted. RESULTS: A total of 28 patients with a mean age of 57.8 years were included. Patients presented with a Cognard grade I in 2 (7%), II a in 5 (18 %), II b in 7 (25%), II a + b in 5 (18%), III in 3 (11%), and IV in 6 (21%) cases. Hemorrhage was the initial presentation in 2 (22%) patients with Cognard grade IV, in 3 with Cognard grade III (33%), in 1 (11%) with Cognard II a + b, and 3 (33%) with Cognard II b. A complete angiographic cure was achieved in 24 (86%) patients-after a single-session embolization in 16 (57%) patients, multiple embolization sessions in 2 (7%), a multimodal treatment with embolization and surgical disconnection in 3 (11%), and with an upfront surgery in 3 (11%). Complete long-term obliteration was demonstrated in 18/22 (82%) at the mean follow-up of 17 months. Fistulas were converted into asymptomatic Cognard I lesion in 4 (14%) patients. CONCLUSION: Posterior fossa dAVFs represent a challenging vascular pathology; however, despite their complexity, an interdisciplinary treatment can achieve high rates of angiographic and symptomatic cure with low morbidity and mortality rates. Long-term surveillance is warranted as late recurrences may occur.

Elimination of saphenous reflux after tributary sclerotherapy: report of two cases.

Most patients with chronic venous disease (CVD) and reflux in the saphenous vein are treated with saphenous stripping or ablation. The venous hemodynamics approach offers the possibility of treating saphenous reflux without eliminating the saphenous vein. We present 2 cases in which venous reflux was eliminated while preserving the great saphenous vein, after treatment with hemodynamic sclerotherapy using a protocol of synergic use of Dextrose and long pulse Nd YAG 1064 laser. These cases show that treating the tributaries responsible for saphenous reflux can correct hemodynamic imbalances and restore normal flow in the great saphenous vein with improvements in symptoms and esthetics. Long-term results are still uncertain.

A maioria dos pacientes com insuficiência venosa crônica e refluxo na veia safena é tratada com retirada ou ablação da safena. A hemodinâmica venosa traz a possibilidade de tratar esses pacientes sem eliminar a veia safena. Nós apresentamos dois casos de refluxo parcial de veia safena magna resolvidos com escleroterapia hemodinâmica. Usamos um protocolo de uso sinergístico de glicose 75% e Nd-YAG laser 1064. Os casos nos mostram que o tratamento das tributárias pode corrigir o refluxo da veia safena e obter melhora clínica e cosmética. Os resultados de longo prazo ainda são incertos.

[Combined use of minimally invasive methods in treatment of varicose veins in an elderly woman]. / Sochetannoe primenenie maloinvazivnykh metodov v lechenii varikoznoi bolezni u pozhilogo patsienta.

The authors describe herein a clinical case report regarding a 70-year-old woman presenting with lower-limb varicosity in the system of the great and small saphenous veins, aneurysmal dilatation of the proximal portion of the great saphenous vein, and an open trophic ulcer of the crus with concomitant hypertension and coronary artery disease. Given these factors, she was subjected to endovenous laser coagulation of the great and small saphenous veins, microfoam echosclerotherapy of the distal portion of the trunk of the great saphenous vein and an incompetent perforating vein of the crus, followed by complete obliteration thereof. On POD 7, she developed positive dynamics in the process of healing of the trophic ulcer, and on POD 50 the ulcer healed completely. Thus, in elderly patients with lower limb varicose veins with incompetence of trunks of the great and small saphenous veins and pronounced trophic impairments of the crus, preference should be given to minimally invasive methods of treatment. Their combination ensures a good therapeutic effect without increasing the risk for local and systemic complications.

[Pharmacological correction of total venous reflux in patients with varicose veins]. / Farmakologicheskaia korrektsiia summarnogo venoznogo refliuksa u bol'nykh s varikoznoi bolezn'iu.

AIM: To evaluate the efficacy of a micronized purified flavonoid fraction in patients with primary venous disease. The study enrolled 31 patients, with varicose veins observed in a total of 47 lower extremities which were divided into 3 groups depending on the CEAP clinical class. The group of class C2 included 19 limbs, with the groups of C3 and C4 comprising 14 limbs each. The patients received a micronized purified flavonoid fraction (Detralex) in a daily dose of 1000 mg for 1 month. The venous function of the lower extremities was examined using venous photoplethysmography before and after the course of pharmacotherapy. Venous refilling time and venous half-refilling time were measured as indicators of total venous reflux. In the overall sample of patients with clinical class C2-C4, a significant increase in venous photoplethysmography parameters was found after the course of administration of the micronized purified flavonoid fraction. Thus, the venous refilling time increased from 15.5 (11; 19) s to 19.3 (13; 25) s, the venous half-refilling time increased from 6.5 (5; 7) s to 7.5 (5; 9) s. At the same time, in the group of patients with clinical class C2 and C3, a significant increase in the venous refilling time was found, and in patients with C4, the increase was not significant. There was an inverse correlation between the increase in venous refilling time after drug exposure and the clinical class of venous insufficiency according to the CEAP, as well as the patient's age. Thus, the administration of the micronized purified flavonoid fraction for 1 month in primary venous disease led to a decrease in the total venous reflux. The effect of the micronized purified flavonoid fraction on the total venous reflux was higher in younger patients and in patients with a lower clinical class of the disease.

External valvuloplasty of the saphenofemoral junction in insufficient great saphenous veins - six weeks results of a prospective multicentre trial.

Background: Varicosis of the great saphenous vein (GSV) is a common disease. Most of the therapeutic concepts attempt to remove or destroy the truncal vein. However, the absence of the GSV could be harmful for further treatments of artherosclerotic disease as the GSV is often used as bypass graft in lower extremity or coronary artery revascularisations. External valvuloplasty (EV) is one of the vein-sparing treatment options. The aim of this clinical study was to describe the outcome, safety and complications of this procedure in a prospective multicentre trial. Patients and methods: The function of the terminal and preterminal valve was restored by external valvuloplasty. Furthermore, multiple phlebectomies of tributaries were performed. Patients were reinvestigated six weeks after surgery. Primary endpoint was the function of the external valvuloplasty measured by diameter of the GSV and the prevalence of reflux in the GSV. The eligibility of the vein as a potential bypass graft was noticed. CEAP class and VCSS scores were analysed. Results: A total of 359 patients were included in the study. After six weeks 297 patients could be reinvestigated. The function of the external valvuloplasty was sufficient in 284 patients (95.6%). Treatment failed in 8 patients (2.6%) due to an occlusion or junctional reflux despite valvuloplasty. The GSV was estimated as suitable as a bypass graft in 261 patients (87.8%). Reflux at the saphenofemoral junction was significantly reduced after treatment and the diameter of the GSV near the saphenofemoral junction significantly decreased from 4.4 mm to 3.8 mm (p < 0.05). The VCSS was significantly reduced from 4.6 preoperatively to 2.6 postoperatively. Conclusions: External repair of the great saphenous vein can reduce venous symptoms and may preserve the great saphenous vein as a bypass graft. Nevertheless, this treatment option is only suitable for a limited number of patients.

Drainage outflow restriction as a parameter associated with cortical venous reflux in craniofacial arteriovenous malformations with cavernous sinus drainage.

PURPOSE: Craniofacial arteriovenous malformations (CF-AVMs) are locally aggressive extracranial lesions. When CF-AVMs involve cavernous sinus (CS) as their draining vein, they represent a special subgroup which may interfere intracranial venous system. In this study, we aimed to analyze the venous drainage patterns of CF-AVMs with CS drainage and to demonstrate how it affected our treatment strategy. METHODS: Cases of CF-AVMs associated with CS drainage were collected from a prospectively collected database of patients with CF-AVMs who underwent endovascular treatment from September 2016 to March 2018. Clinical data and angioarchitectural findings were analyzed. Factors associated with the presence of venous reflux (cortical venous reflux (CVR) or dural sinus reflux (DSR)) were analyzed. RESULTS: Fifteen CF-AVM patients associated with CS drainage were analyzed. Three cases of venous reflux from the CS were identified (CVR, 2; DSR, 1). Lesions with unilateral venous drainage, ≤ 2 draining veins, and the absence of antegrade CS outflow were more likely to develop venous reflux from the CS. We successfully performed additional trans-venous coil embolization of the superior ophthalmic vein in two patients with malformations associated with venous reflux to close this venous connection to the CS. CONCLUSION: CF-AVMs associated with CS drainage confer an increased risk of CVR and DSR, especially in cases where the drainage outflow is restricted. Identification of this venous angioarchitecture is essential in the evaluation and treatment planning of CF-AVMs.

Right jugular foramen dural arteriovenous fistula Cognard IV.

Posterior fossa dural arteriovenous fistulas (dAVFs) are rare vascular malformations. They carry a significant risk of hemorrhage if associated with cortical venous reflux. A 70-year-old man presented with right-sided medullary hemorrhage with pronounced Wallenberg syndrome. Angiography demonstrated right jugular foramen dAVF with direct brainstem venous reflux (Cognard IV). It was fed from multiple branches of the external carotid artery and the vertebral artery, and draining into the ascending pontomesencephalic vein. Primary two-stage transarterial embolization was performed with near-total occlusion of the fistula to prevent it from rebleeding in the acute phase. Because of the patient's significant neurological deficit, the surgery was deferred to later and if the DAVF showed further progression. Follow-up angiography 8 months later demonstrated obvious recurrence and progression of the fistula from adjacent feeders. In the meantime, the patient had a remarkable recovery from the Wallenberg symptoms. To achieve complete occlusion of the fistula, a right far lateral approach was chosen with complete disconnection of the fistula. Postoperative angiography confirmed complete occlusion of the fistula, and the patient remained intact from the procedure.The video can be found here: https://youtu.be/DJvpa8G4olc.

Is there any association between jugular venous reflux and nonpulsatile subjective tinnitus? A preliminary study of four-dimensional magnetic resonance angiography.

OBJECTIVE: To demonstrate whether there is an association between jugular venous reflux and nonpulsatile subjective tinnitus (NST) using real-time four-dimensional magnetic resonance imaging (MRI) angiography. MATERIALS AND METHODS: Patients with unilateral NST who underwent contrast-enhanced MRI with a special protocol were included in the study. Thick slab dynamic maximum intensity projection images were obtained including interleaved stochastic trajectories (TWIST)-MRI examination. All patients were requested to perform Valsalva maneuver during the sequence. Jugular venous reflux grading was performed as follows: absence of reflux or if reflux does not reach the base of the skull: grade 0; if reflux reaches the jugular bulb, but no intracranial contrast is observed: grade 1; and if reflux extends into the intracranial cortical veins and/or the cavernous sinus above the jugular bulb: Grade 2. RESULTS: A total number of 30 patients, 23 male and 7 female, were included in the study. Jugular venous reflux was not identified (Grade 0) in 20 patients. Grade 1 reflux was determined in 7 cases and Grade 2 reflux was observed in 3 cases. Notably, only patients with Grade 2 reflux described worsening of their tinnitus symptoms during the examination and their daily activities as well. CONCLUSIONS: NST might also be associated with hemodynamic problems of the venous system and the MRI protocol starting with TWIST accompanied with Valsalva maneuver is not well-known, yet seems to be a feasible and beneficial method to detect potential jugular venous reflux in NST patients.

Unravelling the Role of MAPKs (ERK1/2) in Venous Reflux in Patients with Chronic Venous Disorder.

Chronic venous disorder (CVeD), is a disorder in which there is a modification in the conditions of blood return to the heart. The disorder may arise from incompetent valves and the resultant venous reflux (chronic venous insufficiency, CVI). The economic burden of CVeD on health systems is high, and research efforts have sought to elucidate the mechanisms involved as possible therapeutic targets. The mitogen-activated protein kinase (MAPK) enzymes mediate a wide array of physiopathological processes in human tissues. In this family of proteins, extracellular signal-regulated kinase (ERK)1/2 plays a direct role in the cell homeostasis that determines the viability of mammalian tissues. This study sought to examine whether ERK1/2 plays a role in venous reflux. This was a prospective study performed on 56 participants including 11 healthy controls. Of the CVeD patients, 23 had venous reflux with CVI (CVI-R) and 22 had no reflux (NR). Distribution by age was: controls <50 years (n = 4) and ≥50 years (n = 7); NR <50 years (n = 9) and ≥50 years (n = 13); CVI-R <50 years (n = 11) and ≥50 years (n = 12). Great saphenous vein specimens were subjected to gene (real-time polymerase chain reaction, RT-qPCR) and protein (immunohistochemistry, IHC) expression techniques to identify ERK1/2. Data was compared between groups using the Mann Whitney U test. Patients with CVI showed significant gene activation of ERK1/2 protein, and, in those with venous reflux, the expression of this gene was significantly greater. The CVI-R group <50 years showed significantly greater ERK1/2 gene expression than their age-matched controls. Expression patterns were consistent with IHC findings. Our studies suggest that ERK1/2 expression is involved in venous vascular disease.
