Foam stability affects the efficacy and incidence of side effects of foam sclerotherapy. Exploring the relationship between foam pressure difference and foam stability can provide ideas and basis for obtaining more stable foam. In the experiment, sodium cod liver oleate foam was selected, and poloxamer 188 (concentration of 0%, 4%, 8%, 12%) was added to realize the change of foam pressure. By using the self-written program to process the foam pictures, the foam pressure difference and the relationship between the foam stability indicators (water separation rate curve, half-life) and the foam pressure difference were obtained. The results showed that at first the foam pressure increased with the increase of the concentration, and then it decreased with the increase of the concentration and reached a peak at the concentration of 4%. The foam pressure difference decreases continuously with the increase of decay time. When the additive concentration is low, the foam average pressure difference increases. And if the additive concentration is too high, the foam average pressure difference decreases. The smaller the foam pressure difference is, the better the foam stability is. This paper lays a foundation for the research on the stability of foam hardener.

Objective: To investigate the effects of primary preventive treatment under endoscope for esophageal and gastric varices on bleeding rate and its relevant factors. Methods: 127 cases with liver cirrhosis accompanied with esophageal and gastric varices without bleeding history were included in the endoscopic and non-endoscopic treatment group, respectively. Informed consent was obtained from both groups. Gastric varices (Lgf) and esophageal varices (Leg) were diagnosed according to LDRf classification criteria, and the corresponding treatment scheme was selected according to the recommended principle of this method.The incidence rate of bleeding from ruptured esophageal varices were observed at 3, 6 months, and 1, and 2 years in the treated and the untreated group, and the patients with different Child-Pugh scores were followed-up for 2 years. Gender, age, etiology, varicose degree, Child-Pugh grade, platelet count, prothrombin activity, portal vein thrombosis, collateral circulation, portal vein width and other factors affecting the bleeding rate were assessed. Measurement data were described as mean ± standard deviation (x¯±s), and qualitative data of categorical variables were expressed as percentage (%), and χ² test was used. Results: 127 cases were followed up for 2 years. There were 55 cases in the endoscopic treatment group (18 cases underwent band ligation, 2 cases underwent band ligation combined with tissue adhesive embolization, 28 cases underwent sclerotherapy, and 7 cases underwent sclerotherapy combined with tissue adhesive embolization). Recurrent bleeding and hemorrhage was occurred in 5 (9.1%) and 28 cases (38.9%), respectively (P<0.05). In addition, there were 72 cases in the untreated group (P<0.05). Severe varicose veins proportions in treated and untreated group were 91.1% and 85.1%, respectively (P>0.05). There was no statistically significant difference in liver cirrhosis-related medication and β-blocker therapy between the treated and untreated group (P>0.05). There was no statistically significant difference in the bleeding rate between the different treated groups (P>0.05). The bleeding rates at 3, 6 months, 1, and 2 years in endoscopic treated and untreated group were 2.00% vs. 2.59% (P>0.05), 2.30% vs. 5.88% (P>0.05), 3.10% vs. 7.55% (P>0.05) and 4.00% vs. 21.62% (P<0.05), respectively. All patients with Child-Pugh grade A, B and C in the treated and the untreated group were followed-up for 2 years, and the bleeding rates were 1.8% vs. 8.1% (P<0.05), 1.1% vs. 9.4% (P<0.05) and 9.1% vs. 10.1% (P>0.05), respectively. There were statistically significant differences in the rupture and bleeding of esophageal and gastric varices, varices degree, Child-Pugh grade and presence or absence of thrombosis formation in portal vein (P<0.05); however, no statistically significant differences in gender, age, etiology, platelet count, prothrombin activity, collateral circulation and portal vein width (P>0.05). There was no intraoperative bleeding and postoperative related serious complications in the treated group. Conclusion: The risk of initial episodes of bleeding from esophageal and gastric varices is significantly correlated with the varices degree, Child-Pugh grade, and portal vein thrombosis. Primary preventive treatment under endoscope is safe and effective for reducing the long-term variceal bleeding risk from esophageal and gastric varices.

OBJECTIVE: To explore the technical details and short-term effects of radiofrequency obliteration of varicose veins of lower extremities guided by combined venography and ultrasound. METHODS: Thirty-seven patients with varicose veins of lower extremities were treated with radiofrequency obliteration using Olympus Celon RFiTT^® under combined guidance of venography and ultrasound. The indications included varicose veins of lower extremities and reflux of the great saphenous vein confirmed by ultrasound. The contraindications included deep vein thrombosis, cardiac pacemaker, severe cardio- and cerebrovascular diseases or coagulation disorders. Under ultrasound guidance, the saphenous vein around knee level was punctured using a 21G needle, and a 7F sheath was introduced. Through the sheath a venography was made, and an Olympus Celon ProCurve radiofrequency catheter was inserted and advanced to the great saphenous vein under road map, and the catheter tip was positioned at the point 2 cm below the sapheno-femoral junction. The swelling anesthesia was made under ultrasound guidance. Then the radiofrequency obliteration was performed with pressing of the treatment section. The venography was repeated to ensure optimal outcomes. If necessary the radiofrequency obliteration could be repeated once to twice. After that the superficial varicose veins were stripping by small incisions under local anesthesia. After operation, medical decompression stocking was utilized immediately and sustained for three months. The clinical data, intraoperative radiation dose, exposure time and short-term effects were retrospectively analyzed. RESULTS: After the operation, all the patients walked out of the operating room by themselves. The success rate of operation was 100%. The intraoperative radiation dose was 1.78-10.12 mGy (mean 6.56 mGy), and the exposure time was 61-448 s (mean 161 s). By 3 months follow-up, the symptoms were alleviated in all the 37 patients, and the occlusion rate was 100%. No complications such as skin burns, ecchymosis and deep venous thrombosis were found. CONCLUSION The short-term effects of radiofrequency obliteration using Olympus Celon RFiTT^® system in a manner of twice fixed point followed by once reciprocating radiofrequency were satisfactory. Radiofrequency obliteration of great saphenous veins guided by venography and ultrasound has not only the advantages of minimal trauma and rapid recovery, but also the advantages of accurate location, exact effect and avoidance of complications.

Introduction: Chronic venous disease is an under-recognized condition which may result in significant morbidities with considerable costs. There is scarce data on chronic venous disease in the Philippines. Methods: The National Nutrition and Health Survey II was conducted to determine the national prevalence of different risk factors and clinical conditions. The primary objective of this study is to determine the prevalence of chronic venous disease in adults aged 20 years and older using the Southern Tagalog Venous Insufficiency Questionnaire (STVIQ). Results: A total of 7,212 subjects, were randomly surveyed. Chronic venous disease has a crude overall prevalence rate of 52.5%, is frequently seen in females (60%) and with increasing age. About 38.6% of the population have typical venous symptoms but only 1.6% have edema, stasis pigmentation and healed venous ulcers. Prevalence of chronic venous disease is not related to urban residence and type of occupation. Conclusion Chronic venous disease in the Philippines is common, reported in approximately five out of 10 Filipinos, most of whom are asymptomatic.

BACKGROUND/AIMS: There is a lack of data on long-term morbidity, particularly dysphagia, following endoscopic variceal band ligation (EVL). The aim of this study are to assess the incidence of dysphagia and variables associated with this complication after EVL.METHODS: We identified individuals who completed at least one session of EVL as their sole treatment for varices from August 2012 to December 2017. Included patients achieved “complete eradication” of varices not requiring further therapy. Patients ≥90 days from their last EVL session completed a modified version of the Mayo Clinic Dysphagia Questionnaire. Individuals with dysphagia were invited to undergo a barium esophagram. Patients with pre-EVL dysphagia were excluded.RESULTS: Of the patients, 68 possessed inclusion criteria, nine (13.2%) died and 20 (29.4%) were lost to follow up. For the remaining 39 (57.4%) patients, 23 were males, mean age of 61.7±8.6 years. The most common etiology of liver disease was hepatitis C virus (n=18; 46.2%). The median number of banding sessions was 2.0 (interquartile range [IQR], 1.0–4.0) with a median of 9.0 bands placed (IQR, 3.0–14.0). Twelve patients (30.8%) developed new-onset dysphagia post-EVL. In univariate analysis, pre-EVL MELD score and non-emergent initial banding were associated with long-term dysphagia. In a regression model adjusted for age, sex, number of bands, and use of acid suppression after EVL, no factor was independently associated with dysphagia (all p>0.05). No strictures were identified on subsequent esophageal evaluation.CONCLUSIONS: Approximately 30% of patients developed new-onset, chronic dysphagia post-EVL. Incident dysphagia was associated with a non-emergent initial banding session. The mechanism for dysphagia remains unknown.

Liver cirrhosis patients are suffering from many complications, which are directly related to a poor prognosis. Although there have been many recent advances in diagnosis and treatment for varix and hepatic encephalopathy in cirrhotic patients, the standard practice for these conditions should consider the different medical resources and etiology of these liver diseases among various countries. The Korean Association for the Study of the Liver published in 2005 a clinical practice guideline for the treatment of cirrhosis complications, and this year, they revised the guideline for treating gastroesophageal varices and hepatic encephalopathy. This review summarizes the revised practice guideline and emphasizes the updated recommendation.

Cervical varix is rare and can develop due to various conditions in pregnancy. Most cases of cervical varix during pregnancy are diagnosed in the second or third trimester and are usually associated with abnormal placental location, such as placenta previa or low-lying placenta. A 23-year-old woman with cervical varix bleeding visited our institution at 8 weeks of gestation. This case report describes cervical varix bleeding that developed into a venous thrombus in the first trimester. Ultrasonography with color Doppler and magnetic resonance imaging could be helpful in diagnosis.

Popliteal vein aneurysms (PVAs) represent a rare form of venous aneurysms and necessitate prompt management because of their well-established risk of pulmonary embolism (PE). Herein, we report a rare case of PVA without PE, successfully treated with open surgical repair. A 27-year-old man presented to our vascular clinic with chronic pain and swelling in his left lower limb. He had a long history of facial surgeries for the removal of congenital multiple osteomas. Physical examination revealed varicosities with an abnormal distribution. Duplex ultrasound showed a left PVA measuring 2.3 cm in diameter and 4 cm in length. Open surgical excision of the PVA with lateral venorrhaphy was performed through a medial approach. Prophylactic anticoagulation was performed postoperatively. In this case, the PVA was detected, with a high degree of suspicion by the clinician, before it caused fatal PE. The patient was successfully treated with aneurysm excision and lateral venorrhaphy.

A 58-year-old male patient with severe claudication due to thrombosis of the left ilio-femoro-popliteal artery aneurysm. He also had a venous stasis ulcer with a history of multiple embolotherapy of arteriovenous malformation. Duplex sonography revealed reflux and varicose veins of the left great saphenous vein (GSV). A sequential bypass surgery was performed that consisted of excision of the left external iliac and common femoral artery aneurysm, external iliac to deep femoral interposition with an expanded polytetrafluoroethylene graft, and femoro-posterior tibial artery bypass with the reversed left GSV. Symptoms of claudication were alleviated and the chronic ulcer was healed in time. To our knowledge, this is the first report of successful bypass in a patient with arterial aneurysm, arteriovenous malformation, and venous insufficiency that can be diagnosed as an atypical case of Parkes Weber syndrome. Long-term follow-up is needed to define the fate of aneurysms and varicose vein graft.

PURPOSE: There is limited data on the outcomes of radiofrequency ablation (RFA) for large diameter saphenous veins. This study aimed to determine whether the large-diameter great saphenous vein (GSV) affected closure rate, complications, and clinical and quality of life (QoL) improvement. METHODS: From January 2012 to September 2016, a total of 722 limbs were treated with ClosureFAST RFA in a single center. Patients were divided into 2 groups according to the vein diameter measured 3 cm below the saphenofemoral junction (group A ≤ 12 mm, group B > 12 mm). Vein closure was evaluated with duplex scan at 3–5 days, 1, 3, 6, and 12 months postoperatively. The incidence of complications, improvements in symptoms (measured by the Venous Clinical Severity Score [VCSS]) and QoL (measured by the Aberdeen Varicose Vein Symptom Severity Score [AVSS]) were evaluated. RESULTS: Groups consisted of 663 GSVs in group A (mean diameter, 6.00 ± 1.74 mm) and 59 in group B (mean diameter, 13.17 ± 1.28 mm). Vein closure rates at 12 months were 98.9% in group A and 100% in group B (P = 0.428). There was no significant difference in the incidence of complications. Both groups showed marked improvements in the VCSS and the AVSS with no significant differences. CONCLUSION: For large-diameter veins, RFA showed comparable outcomes in terms of closure rate, complications, clinical and QoL improvements.
