Modification of varicose vein stripping to achieve immediate compression in a theatre setting with minimum personnel

Compression bandaging is a key aspect following stripping for varicose vein surgery. With adequate compression, formation of subcutaneous hematoma can be prevented and thereby prevent revascularisation of the hematoma leading to recurrence of varicose vein. Various techniques exist to provide compression. Our modification provides an easy alternative to achieve immediate compression following stripping and is especially useful in a setting where staff is very limited. Materials required include a 10 cm width gauze bandage, 1% lidocaine with epinephrine, and number 1 silk suture in addition to the conventional tools for open varicose vein surgery. The gauze bandage is introduced along with the stripper which is passed from groin to below knee. The bandage is kept in the subcutaneous tunnel till perforator ligation, groin wound closure and application of compression bandage. The gauze bandage is removed through a small window within the compression stocking below the knee and the wound closed in a single layer. From 2005 to 2020, 410 patients underwent varicose vein surgery with the modified technique. Of these, 1 patient developed complication secondary to hematoma formation which was managed conservatively. Our modification of the varicose vein stripping technique is shown to be a cost effective and simple technique which provides immediate compression and effortlessly facilitates haemostasis till wounds are closed and compression stockings applied. in various literatures.

Surgical management of varicose veins: a comparative analysis between radiofrequency ablation and open surgery with venous stripping

Background: Varicose veins are a common condition affecting the lower limbs. Apart from having cosmetic problem, if not treated in time it can have some serious complications and are difficult to treat. Multiple modes of surgical management exist for the disease.Methods: This is a prospective clinical study, done over a period of 5-years, between February 2015 to February 2020. Patients were divided into 2 groups: group I (n=103) included those who underwent open surgical to treatment with venous stripping. Group II (n=104) included those who subjected to Radiofrequency ablation (RFA). Groups were selected with comparable physical parameters. Various parameters like bleeding, hematoma, blood requirement, postoperative inflammation, pain, numbness, mobilization, date of discharge and resuming duties were compared. All patients were followed up for 1y ear.Results: Majority of our patients belongs to age group 20-40 years with mean age of 35year in both groups. Male has dominance over female with male to female ratio 4:1. We noticed significant complication in group I than group II, such as bleeding (20:1), hematoma (5:0), inflammation (60:1) and blood requirement (1:0). In group II, we noticed early mobilization of patient (1day v/s 3 days), discharge from hospital (1day v/s 5 days) and resuming duties (5 days v/s 2 weeks).Conclusion: RFA keeps an edge over open surgical treatment with venous stripping.

Trends on management of superficial venous disease

Venous disease is more common in the society but less addressed than peripheral arterial disease. This is commonest in people who are sedentary workers, people standing for prolonged period, obase. Usually this group of people do not visit a doctor until it restricts him from regular work, ultimately causing a burden in the community. Early diagnosis of venous disease and its’ management is important. Understanding venous pathology, educating people about disease, conducting awareness program among target group of people are essential. Superficial venous disease includes both venous insufficiency and venous thrombosis. Management options of varicose vein and thrombophlebitis are discussed in the presentation.

La vena varicosa epidural imita el prolapso de disco y causante de un dolor radicular severo: Reporte de un caso / Epidural varicose vein mimic disc prolapse and causing a severe radicular pain: A case report

Venous varicose of epidura is considered a rare cause of nerve root and thecal sac compression and impingement that leads to lower limb radiculopathy. The purpose of this study is to draw attention to this problem during operation. It also aims to focus shed a light on using magnetic resonance imaging (MRI) before the operation. This research also attempts to evaluate the outcome of the surgery. Symptoms of epidural varicose with radiculopathy are rare and the diagnosis is often inaccurate by preoperative clinical examination and radiology investigations. Thus, in many cases the diagnosis is made intra- operatively. The case was a 40 years old female who consulted our outpatient clinic complaining from acute radicular pain in the lower back and down of her right lower limb. MRI was done for her and showed paracentral disc herniation. Intra operatively, an abnormal dilatation of epidural vein impingement on L4 nerve root with no foraminal stenosis was seen. We initiated a thermo coagulation of the epidural vein from proximal to distal ends at disc level and used gel foam patch to control bleeding that was removed all at the end of operation. Then, coagulation ablation was performed. The operation resulted in relief of symptoms and neurologic recovery occurred during follow up period. According to our case and previously published case reports, the outcome is good with recovery of neurological signs and symptoms that can be obtained by coagulation ablation of epidural varicose vein.

Evaluation of healing of varicose ulcers after endovenous laser ablation of great saphenous vein

Background: Varicose veins are permanently swollen, tortuous and elongated while standing due to back flow of blood caused by incompetent valve closure which result in venous congestion .they are of two types primary and secondary varicosities .The main symptoms are tingling, itching, pain, fatigue, a heavy feeling in the legs especially if one has to stand for a long time. Ulcers and thrombophlebitis are possible complications. The aim of this study is to assess the outcome of laser ablation of great saphenous vein on healing of varicose ulcers.Methods: A prospective study conducted at Suez Canal University Hospitals and Nasser Institute Hospital in Cairo on 20 patients complaining varicose ulcers due to incompetent saphenous femoral junction.Results: All patients had improvement in Abrdeen Varicose vein questionnaire after endovenous laser ablation (EVLA) during the first, second and third follow up visits when compared with preoperative scores. The Aberdeen Varicose vein questionnaire ranged from 8 to 18 before the procedure, with a mean of 12.11, ranged from 3 to 11 at the first follow up visit with a mean of 7.07, ranged from 2 to 10 at the second follow up visit with a mean of 4.89 and ranged from 2 to 10 at the third follow up visit with a mean of 3.85, p value is less than 0.001 compared to the pre-operative data. During the assessment of the patients of our study after 6 months of continuous follow up, we found that the healing rate of the patients who underwent laser ablation of great saphenous vein were (91.67) (p=0.769).Conclusions: EVLA of great saphenous vein leads to better wound healing rates in treating patients with varicose ulcers.

Hemoperitoneo secundario a la ruptura espontánea de una variz uterina en una paciente con embarazo a término: reporte de un caso y revisión bibliográfica / Hemoperitoneum secondary to spontaneous rupture of a uterine varice in a patient with a full-term pregnancy: A case report and literature review

Resumen: ANTECEDENTES: La ruptura de una variz útero-ovárica durante el embarazo es un evento poco frecuente, pero con importantes implicaciones en la morbilidad y mortalidad materna y neonatal. Puede acontecer en cualquier momento del embarazo, aunque su frecuencia se incrementa en el tercer trimestre y durante el parto. CASO CLÍNICO: Paciente de 32 años, con 39 semanas de embarazo, en control prenatal, sin contratiempos, que acudió al servicio de Urgencias debido a un dolor abdominal generalizado e intenso, de dos horas de evolución. A la exploración física se encontraron: hipotensión, taquicardia y anemia moderada; hemoglobina de 8.9 g/dL y hematócrito de 35%. La evaluación fetal reportó: taquicardia y posterior bradicardia. Se decidió finalizar el embarazo por cesárea urgente, donde se objetivó hemoperitoneo de aproximadamente 1 L y sangrado activo procedente de la ruptura de un vaso en la parte posterior de la pared uterina que se suturó con puntos dobles. El desenlace materno y neonatal fue favorable. CONCLUSIONES: La rotura de las várices útero-ováricas puede originarse por hemoperitoneo masivo y resultar en consecuencias graves para la madre y el feto. La sospecha diagnóstica y la laparotomía de urgencia son decisivas para cohibir el sangrado y lograr un desenlace materno y fetal satisfactorios.

Abstract: BACKGROUND: The rupture of an utero-ovarian varicose vein during pregnancy is an infrequent event but it can have important implications for maternal and neonatal morbidity and mortality. It can occur at any time during pregnancy, although its frequency is increased in the third trimester and during labor. CLINICAL CASE: A single gestation of 39 weeks, with regular monitoring without incidents, who went to the emergency department for intense and generalized abdominal pain of two hours of evolution. The patient presented hypotension and tachycardia and moderate anemia with a hemoglobin of 8.9 g/dL and a hematocrit of 35%. Fetal monitoring showed fetal tachycardia with decreased variability and subsequent bradycardia. It was decided to end the pregnancy by an urgent caesarean section where a hemoperitoneum of approximately 1 liter was observed. As well, and active bleeding resulting from the rupture of a posterior uterine wall vein was noted and controlled with hemostatic sutures. The maternal and neonatal results were favorable. CONCLUSIONS: Spontaneous rupture of utero-ovarian varicose veins can be the cause of massive hemoperitoneum and can maternal and fetal serious consequences. A promptly suspected diagnosis and an urgent laparotomy are vital to restrain bleeding and achieve a good maternal and fetal result.

Abstract BACKGROUND: Klippel-Trenaunay syndrome is a neurocutaneous syndrome with vascular repercussion whose characteristic triad is a cutaneous vascular nevus, varicose veins and asymmetric soft tissue and bone hypertrophy, which affect one or more limbs, during pregnancy these malformations increase, with pelvic and intra-abdominal repercussion. In the world literature, fewer than 100 cases of complicated pregnancies with this syndrome have been reported. OBJECTIVE: The second case of complicated pregnancy with Klippel-Trenaunay syndrome treated in our institution is reported, given its high morbidity, due to the high risk of severe complications such as venous thromboembolism or excessive bleeding in the intrapartum period. CLINICAL CASE: A 16-year-old, with a Klippel-Trenaunay syndrome diagnosed at fifteen, sent to our unit, with a third-trimester pregnancy, for resolution of pregnancy. Preoperative studies were performed blood count, coagulation tests, reported without alterations; as well as Doppler ultrasound of the uterine segment, without an increase in vasculature. It is scheduled for caesarean section, which is performed without intraoperative complications, with total bleeding of 600 cc, with an increase in vascularity at the colon level. She remains in immediate postoperative surveillance for 48 hours in an intensive care unit, without presenting haemorrhagic or ischemic complications. She is discharged at 72 hours, with thromboprophylaxis, analgesic and antibiotic. CONCLUSION: Pregnancy in patients with this syndrome implies high morbidity and mortality, which can be prevented with multidisciplinary management, anticipating potential complications.

CHIVA to treat saphenous vein insufficiency in chronic venous disease: characteristics and results / CHIVA para tratar insuficiência de veia safena em doença venosa crônica: características e resultados

There is considerable debate in the literature with relation to the best method to treat patients with chronic venous disease (CVD). CHIVA is an office-based treatment for varicose veins performed under local anesthesia. The aim of the technique is to lower transmural pressure in the superficial venous system and avoid destruction of veins. Recurrence of varicosities, nerve damage, bruising and suboptimal aesthetic results are common to all treatments for the disease. This paper evaluates and discusses the characteristics and results of the CHIVA technique. We conclude that CHIVA is a viable alternative to common procedures that is associated with less bruising, nerve damage, and recurrence than stripping saphenectomy. The main advantages are preservation of the saphenous vein, local anesthesia, low recurrence rates, low cost, low pain, and no nerve damage. The major disadvantages are the learning curve and the need to train the team in venous hemodynamics

Existe uma grande discussão na literatura sobre o tratamento da doença venosa crônica (DVC). A cura conservadora e hemodinâmica da insuficiência venosa em ambulatório (CHIVA) consiste no tratamento ambulatorial de varizes sob anestesia local. O objetivo da técnica é diminuir a pressão transmural no sistema venoso superficial para evitar a destruição das veias, incluindo as veias safenas. Recorrência de varizes, lesão de nervos, hematomas e resultado estético abaixo do ideal são uma constante em todos tratamentos de varizes. O objetivo desta revisão é avaliar e discutir a técnica CHIVA quanto a suas características e resultados. A CHIVA é uma alternativa válida frente aos outros procedimentos, apresentando menos hematomas, recorrência e lesão nervosa que a safenectomia. Preservação da veia safena, anestesia local, baixa taxa de recorrências, baixo custo, pouca dor e ausência de lesões nervosas são as principais vantagens. A longa curva de aprendizado para treinar a equipe em hemodinâmica venosa é a principal desvantagem

Retrospective Analysis of Risk Factors for Venous Thromboembolism in 283 Patients with Lung Cancer during Systemic Therapy / 中国肺癌杂志

BACKGROUND@#Patients with lung cancer have high risk of developing venous thromboembolism (VTE), which has been shown to have a significant impact on mortality. This study was to identify the incidence of VTE in lung cancer patients during systemic therapy and to analyze the risk factors associated with it.@*METHODS@#We retrospectively analyzed the cases of 283 patients with lung cancer who received systemic therapy in the Department of Medical Oncology and Radiation Sickness, Peking University Third Hospital, from January 2016 to December 2018. Chi-square test and multivariate analyses were used to assess the correlation between clinical features and VTE.@*RESULTS@#Of the patients we observed, 34 developed VTE, with an incidence of 12.01% (34/283). In patients with lower extremity varicose vein (LVV), there was an increase in the incidence of VTE (50.00% vs 9.89%, P=0.001). The incidence VTE in patients with distant metastasis was higher than that in patients without distant metastasis, and higher than that in patients with tumor-free (14.05% vs 14.00% vs 2.08%, P=0.024). The incidence of VTE in patients with active tumor was also significantly higher than that in patients without it (16.93% vs 8.18%, P=0.025). Patients with hypoalbuminemia (albumin 0.3 µg/mL) developed more VTE than those without did (17.93% vs 5.80%, P=0.006). There were no significant correlations between pathological types, blood cell count before systemic therapy including leukocyte, hemoglobin and platelet, or antiangiogenic drugs and VTE. Multivariate analysis showed that LVV, hypoalbuminemia and elevated level of D-dimer were independent risk factors of VTE.@*CONCLUSIONS@#LVV, serum albumin and D-dimer level may be potential and more effective predictors of VTE in lung cancer patients during systemic therapy. Basing on these factors, new predictive model can be built, and further study to validate its efficacy is required.

FOXC2-AS1 regulates phenotypic transition, proliferation and migration of human great saphenous vein smooth muscle cells

OBJECTIVES: In varicose veins, vascular smooth muscle cells (VSMCs) often shows phenotypic transition and abnormal proliferation and migration. Evidence suggests the FOXC2-Notch pathway may be involved in the pathogenesis of varicose veins. Here, this study aimed to explore the role of long non-coding RNA FOXC2-AS1 (FOXC2 antisense RNA 1) in phenotypic transition, proliferation, and migration of varicose vein-derived VSMCs and to explore whether the FOXC2-Notch pathway was involved in this process. METHODS: The effect of FOXC2-AS1 on the proliferation and migration of human great saphenous vein smooth muscle cells (SV-SMCs) was analyzed using MTT assay and Transwell migration assay, respectively. The levels of contractile marker SM22α and synthetic marker osteopontin were measured by immunohistochemistry and Western blot to assess the phenotypic transition. RESULTS: The human varicose veins showed thickened intima, media and adventitia layers, increased synthetic VSMCs, as well as upregulated FOXC2-AS1 and FOXC2 expression. In vitro assays showed that FOXC2-AS1 overexpression promoted phenotypic transition, proliferation, and migration of SV-SMCs. However, the effect of FOXC2-AS1 overexpression could be abrogated by both FOXC2 silencing and the Notch signaling inhibitor FLI-06. Furthermore, FOXC2-AS1 overexpression activated the Notch pathway by upregulating FOXC2. CONCLUSION: FOXC2-AS1 overexpression promotes phenotypic transition, proliferation, and migration of SV-SMCs, at least partially, by activating the FOXC2-Notch pathway.

Resumen 20. La enfermedad varicosa es un problema común que afecta a gran parte de la población mundial, principalmente en mujeres, agravado por una condición de embarazo. Esta revisión narrativa tiene el objetivo de conocer la evidencia científica disponible sobre aspectos diagnósticos, factores de riesgo e intervención conservadora o invasiva, incluyendo cirugía de las venas varicosas en miembros inferiores en mujeres embarazadas. La búsqueda bibliográfica se llevó a cabo en las bases de datos PubMed, Biblioteca Cochrane y EBSCO Host entre los años 2009 y 2017. Se recuperó 50 referencias bibliográficas y se seleccionó seis documentos para el análisis. Respecto del diagnóstico se lleva a cabo mediante la observación, examen directo, historia clínica y exámenes más específicos como el doppler. La síntomatología más común que se presenta es el dolor en miembros inferiores, edema, pesadez, prurito y calambres. La intervención para el tratamiento a mujeres embarazadas es la terapia conservadora, aunque solo en casos excepcionales se determinará otro tipo de tratamiento. En este proceso, la educación tiene un rol muy importante en la seguridad de la madre y el feto, cuyo abordaje debe ser dado por un equipo de profesionales en salud. Se concluye que existe controversias respecto de la patogenia de esta morbilidad durante el embarazo, por lo tanto, no se ofrece otros tratamientos distintos a los recomendados desde el año 50, de manera que hay una gran necesidad de llevar a cabo estudios robustos que demuestren cuáles son las mejores medidas profilácticas más novedosas y de tratamiento desde el inicio del embarazo, además de promover la prevención de la aparición posterior, de tal manera que esté asegurada la salud de la mujer y, consecuentemente, la de su bebé.

Abstract 24. The varicose disease is a common problem that affects a large part of the world population in greater percentage of women, added to its condition the presence of pregnancy. This narrative review has the objective of knowing the available scientific evidence on diagnostic aspects, risk factors and conservative or invasive intervention including surgery of varicose veins in lower limbs in pregnant women. The bibliographic search was carried out in PubMed, Cochrane Library and EBSCO Host databases between 2009 and 2017. Fifty bibliographical references were retrieved and six documents were selected for analysis. Regarding the diagnosis is carried out through observation, direct examination, clinical history, more specific examinations such as Doppler. The most common symptom presented is a pain in the lower limbs, oedema, heaviness, pruritus and cramps. The intervention for the treatment of pregnant women is conservative therapy, only in exceptional cases will be determined another type of treatment. Education plays a very important role in the safety of the mother and the fetus. The approach to these women must be given by a team of health professionals. It is concluded that there are controversies regarding the pathogenesis of this morbidity during pregnancy and, therefore, no treatments other than those recommended since year 50 are offered, so there is a great need to carry out robust studies that show which are the best new prophylactic measures and treatment from the beginning of pregnancy, in addition to promoting the prevention of subsequent appearance, in such a way that the health of the woman and consequently that of her baby is ensured.

A Study on Prevalence and Risk Factors for Varicose Veins in Nurses at a University Hospital

BACKGROUND: Lower-limb varicose veins (VVs) are common and known to have a higher prevalence among people who work in occupations requiring prolonged standing. In the Republic of Korea, however, VV-related occupational factors have seldom been examined. This study was conducted to assess the prevalence of VVs among nurses, an occupational group considered to be at high risk of VVs, and determine the occupational risk factors of prolonged standing. METHODS: Between March and August 2014, a questionnaire survey coupled with Doppler ultrasonography was conducted on the nurses working at a university hospital. RESULTS: A total of 414 nurses participated in the survey and diagnostic testing. From the survey analysis and test results, the prevalence of VVs in nurses was estimated to be 16.18%. Significant factors for venous reflux were age [odds ratio (OR) = 1.06, 95% confidence interval (CI) = 1.03–1.10], pregnancy (OR = 2.15, 95% CI = 1.17–3.94), and delivery (OR = 2.02, 95% CI = 1.08–3.78). The statistical significance of these factors was verified after risk adjustment for sociodemographic factors (OR = 3.40, 95% CI = 1.27–9.09). CONCLUSION: Factors significantly associated with venous reflux were increasing age and prolonged working hours (≥ 4 hours) in a standing position (OR = 2.80, 95% CI = 1.08–7.25), even after risk adjustment for sociodemographic factors. This study is significant in that an objective diagnosis of VVs preceded the analysis of the risk factors for VV incidence, thus verifying objectively that VVs are associated with occupations requiring prolonged hours of working in a standing position.

Evaluation on efficacy and safety of blood-letting tape used in lower extremity varicose vein operation / 重庆医学

Objective To investigate the efficacy and safety of exsanguination band used in the lower extremity varicose vein operation.Methods A total of 158 cases of lower extremities varicose veins in this hospital served as the research subjects.All cases underwent the high ligation of great saphenous vein combined with punctate stripping operation.Among them,117 cases intraoperatively used the exsanguination band for blocking the lower limb blood flow (observation group),41 cases did not use the exsanguination band (control group).Then the intraoperative bleeding volume,operation time,pain degree and postoperative complications were observed in the two groups.Results Compared with the control group,the operation time,intraoperative blood loss,hematoma score,prothrombin time (PT) and fibrinogen (FIB) in the observation group were significantly decreased (P＜0.05),while activated partial thrombin time (APTT) and thrombin time (TT) were significantly increased(P＜0.05).The lower limb blood flow occlusion time in the observation group was 45-62 min with an average of (46.68-5.53) min.The sensory score and pain score at postoperative 2 weeks had no statistical difference between the two groups (P＞0.05).No arterial abnormalities and no obvious ischemic injury were found in the injured limbs of 2 groups.Conclusion Applying the exsanguination band for transiently blocking the blood flow can effectively shorten the operation time,reduces the intraoperative bleeding amount and decreases the subcutaneous hematoma formation risk with high safety.

Early experience of transilluminated cryosurgery for varicose vein with saphenofemoral reflux: review of 84 patients (131 limbs)

PURPOSE: Varicose veins with great saphenous vein (GSV) insufficiency is prevalent. Among various surgical treatments for varicose veins, cryosurgery of GSV is an alternative minimally invasive technique that could leave fewer scars and replace conventional stripping with ambulatory phlebectomy. This study sought to assess outcomes including efficacy and safety of cryosurgery for varicose veins. METHODS: One hundred thirty-one limbs in 84 patients (37 male, 47 female; mean age, 53.3 years) with varicose veins were treated with cryosurgery over a 2-year period. The patients were followed for postoperative complication with surveillance of recurrence. The analyzed variables included age, sex, symptom, operative time (from skin incision to the application of elastic bandages on the legs for compression purposes), and postoperative complications including bruising, hematoma, superficial thrombophlebitis, cellulitis, seroma, cutaneous nerve damage, and wound complication. RESULTS: The mean operative time was 64.7 minutes for both limbs and 44 minutes for single limbs. The median number of incisions was 2. For stripping of GSV, one incision at the groin was necessary. Postoperative complications included an episode of hematoma in 3 limbs (2.3%), cutaneous nerve damage in 3 limbs (2.3%), cellulitis in 2 patients (1.5%), and seroma in 1 limb (0.8%). No wound infection, thrombophlebitis or deep venous thrombosis was observed. During follow-up (mean follow-up period, 13.5 months; range, 3–28 months), there was no recurrence. CONCLUSION: Cryosurgery to treat varicose veins is an effective and safe treatment modality in terms of postoperative complication, cosmetic result, and recurrence.

Objective To investigate the clinical effectiveness of foam sclerotherapy for lower extremity varicose vein with deep venous valve incompetence.Methods A retrospective study was carried out in 124 patients (185 limbs) receiving foam sclerotherapy in our department.Sixty-one limbs diagnosed as deep venous valve incompetence were categorized as the observation group,while 124 limbs without that were the control group.The main outcome were success rate,remission rate of various symptoms and signs,the scores of CEAP and CIVIQ.Results The follow up rate was 69.3％,and the follow-up period ranged from one to nine months.There was no statistical difference in the success rate between the observation group (93.4％) and control group (94.4％)(P＞0.05).However,the symptom of heaviness and oedema and the CIVIQ scores in observation group be inferior to the control group,and the difference of them were statistically significant (P＜0.05).Conclusion Deep venous valve incompetence could not decrease the success rate of foam sclerotherapy,but may influence the remission of some symptoms.It should be supplemented with medical elastic stockings or ringing of femoral veins.

Clinico‑histopathological study of varicose vein and role of matrix metalloproteinases‑1, matrix metalloproteinases‑9 and tissue inhibitor of matrix metalloproteinase‑1 in varicose vein formation.

Background and Aims: Varicose vein (VV) is an important cause of morbidity in the young and elderly population. Many studies of the Western country suggest that matrix metalloproteinases (MMPs) and tissue inhibitors of MMPs have a crucial role in the pathogenesis of VV, but limited work has been done in Indian population. The aim of this study is to study detailed histology of VV and to see the expression of MMP‑1, MMP‑9 and tissue inhibitor of matrix metalloproteinase‑1 (TIMP‑1). Materials and Methods: A total of 63 cases of VV and 10 control leg veins were included in this prospective study. Paraffin sections of VV were prepared. Hematoxylin and eosin (H and E), Masson trichrome and Verhoeff’s staining were performed. Immunohistochemistry of VV was done with MMP‑1, MMP‑9, and TIMP‑1 antibodies. Cytoplasmic expression of MMP‑1, MMP‑9 and TIMP‑1 were graded as intense positive (++), weak/slight positive (+), and absent (−). Results: Focal intimal thickening (47.6%), increased medial thickening (73%) and fragmentation of elastin fibers (84.1%) were the major histological changes noted in H and E and special stained sections. MMP‑1 expression increased in all layers of VV in 58 cases (92.1%) as compared to control veins. As compared to the control veins, intimal and adventitial expression of MMP‑9 were increased in 31 (49.2%) and 40 (63.5%) cases, respectively. Expression of TIMP‑1 was absent in both the varicose and the control veins. Conclusion: Increased expression of MMP‑1 and MMP‑9 suggests they have an important role in the pathogenesis of VV.

Lower Limb Varicose Vein or Swelling Secondary to Cockett Syndrome / 中国微创外科杂志

Objective To explore the treatment method and curative effect for lower limb varicose vein or swelling secondary to Cockett syndrome. Methods From March 2014 to March 2015,a total of 25 cases of lower limb varicose vein (22 cases)or swelling (3 cases)secondary to Cockett syndrome were treated with percutaneous transluminal angiography (PTA).Stents were placed in the veins in 19 cases,and 22 patients with varicose veins were treated with the great saphenous vein high ligation and point type stripping at secondary stage. Results The operations were successful.The iliac vein PTA was performed in all the 25 patients.The iliac vein stent implantation was performed in 17 cases of varicose veins and 2 cases of lower limb swelling.The saphenous vein high ligation and point type stripping was performed in 22 cases of varicose veins of lower extremity at 1 month after the interventional treatment.Postoperatively,no complications such as lower limb swelling,infection,or deep vein thrombosis occurred.Follow-up at the first postoperative month showed 20 cases of cured and 5 cases of alleviated.Follow-up for 3 -15 months (mean,12.4 months)in the 25 cases showed no lower limb swelling,recurrence of varicose vein,or deep vein thrombosis. Conclusions Cockett syndrome patients can be treated with iliac vein PTA.Whether or not a stent placement is required is determined according to the extent of vein stenosis.Postoperatively,lower limb swelling can be significantly alleviated.For patients with secondary varicose vein of lower extremity,saphenous vein ligation and point type stripping is recommended after 1 month.
