Comparing Safety and Efficacy of Rivaroxaban with Warfarin for Patients after Successful Stent Placement for Chronic Iliofemoral Occlusion: A Retrospective Single Institution Study.

OBJECTIVE: The aim was to compare the safety and effectiveness of rivaroxaban and warfarin as anticoagulants for treating patients with post-thrombotic syndrome (PTS) with chronic iliofemoral venous occlusion undergoing iliofemoral venous stenting. METHODS: This single institution retrospective study analysed patients with PTS with chronic iliofemoral venous occlusion who were prescribed rivaroxaban or warfarin for one year after successfully undergoing iliofemoral venous stenting. The primary safety and efficacy endpoints were bleeding complication rate and primary patency rate at one year. Secondary outcomes included Villalta score, symptom recurrence rate, ulcer healing rate, and clinically driven target lesion revascularisation (CD-TLR) rate during follow up. RESULTS: From January 2016 to December 2017, 154 legs from 154 patients were included in this study (69 in rivaroxaban group and 85 in warfarin group). The groups were well matched for patient demographics, clinical characteristics, and procedural details. There was no significant difference between the rivaroxaban group and warfarin group in bleeding complication rate (10% vs. 16%, p = .23, hazard ratio [HR] 0.58, 95% confidence interval [CI] 0.25 - 1.37) at one year, as well as major bleeding complication rate (0% vs. 2%, p = .20, HR 0.16, 95% CI 0.01 - 2.61) and minor bleeding complication rate (10% vs. 14%, p = .40, HR 0.67, 95% CI 0.27 - 1.66). The primary patency rate was higher in the rivaroxaban group at one year (84% vs. 71%, p = .049, HR 0.50, 95% CI 0.26 - 0.96) and at two years (79% vs. 63%, p = .037, HR 0.52, 95% CI 0.29 - 0.93). At a mean follow up of 24 months (range 1 - 42 months), the rivaroxaban group had a significantly lower post-operative Villalta score (4.87 ± 3.51 vs. 6.88 ± 5.85, p = .010, t = 2.64, 95% CI 0.50 - 3.52), lower rate of symptom recurrence (4% vs. 32%, p < .001), lower CD-TLR rates (3% vs. 13%, p = .039), and higher ulcer healing rate (90% vs. 59%, p = .004) than the warfarin group. CONCLUSION: For PTS patients with chronic iliofemoral venous occlusion undergoing iliofemoral venous stenting, rivaroxaban probably exhibited similar safety but superior efficacy to warfarin. However, further prospective control studies with large sample size are necessary to confirm the results.

Rutosides for treatment of post-thrombotic syndrome.

BACKGROUND: Post-thrombotic syndrome (PTS) is a long-term complication of deep venous thrombosis (DVT) that is characterised by pain, swelling, and skin changes in the affected limb. One in three patients with DVT will develop post-thrombotic sequelae within five years. Rutosides are a group of compounds derived from horse chestnut (Aesculus hippocastanum), a traditional herbal remedy for treating oedema formation in chronic venous insufficiency (CVI). However, it is not known whether rutosides are effective and safe in the treatment of PTS. This is the second update of the review first published in 2013. OBJECTIVES: To determine the effectiveness (improvement or deterioration in symptoms) and safety of rutosides for treatment of post-thrombotic syndrome (PTS) in patients with DVT compared to placebo, no intervention, elastic compression stockings (ECS) or any other treatment. SEARCH METHODS: The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase and CINAHL databases and World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers to 21 August 2018. SELECTION CRITERIA: Two review authors independently assessed studies for inclusion. Studies were included to allow the comparison of rutosides versus placebo or no treatment, rutosides versus ECS, and rutosides versus any other treatment. Two review authors extracted information from the trials. Disagreements were resolved by discussion. DATA COLLECTION AND ANALYSIS: Data were extracted using designated data extraction forms. The Cochrane 'Risk of bias' tool was used for all included studies to assist in the assessment of quality. Primary outcome measures were the occurrence of leg ulceration over time (yes or no) and any improvement or deterioration of post-thrombotic syndrome (yes or no). Secondary outcomes included reduction of oedema, pain, recurrence of DVT or pulmonary embolism, compliance with therapy, and adverse effects. All of the outcome measures were analysed using Mantel-Haenzel fixed-effect model odds ratios. The unit of analysis was the number of patients. We used GRADE to assess the quality of the evidence for each outcome. MAIN RESULTS: Ten reports of nine studies were identified following searching and three studies with a total of 233 participants met the inclusion criteria. Overall quality of evidence using the GRADE approach was low, predominantly due to the lack of both participant and researcher blinding in the included studies. The quality of the evidence was further limited as only three small studies contributed to the review findings. A subjective scoring system was used to obtain the symptoms of PTS so it was important that the assessors were blinded to the intervention. One study compared rutosides with placebo, one study compared rutosides with ECS and rutosides plus ECS versus ECS alone, and one study compared rutosides with an alternative venoactive remedy. Occurrence of leg ulceration was not reported in any of the included studies. There was no clear evidence to support a difference in PTS improvement between the rutosides or placebo/no treatment groups (OR 1.29, 95% CI 0.69 to 2.41; 164 participants; 2 studies; low-quality evidence); or between the rutosides and ECS groups (OR 0.80, 95% CI 0.31 to 2.03; 80 participants; 1 study ; low-quality evidence). Results from one small study reported less PTS improvement in the rutosides group compared to an alternative venoactive remedy (OR 0.18, 95% CI 0.04 to 0.94; 29 participants; 1 study; low-quality evidence). There was no clear evidence to support a difference in PTS deterioration when comparing rutosides with placebo/no treatment (OR 0.61, 95% CI 0.19 to 1.90; 80 participants; 1 study); with ECS (OR 0.61, 95% CI 0.19 to 1.90; 80 participants; 1 study); or an alternative venoactive remedy (OR 0.19, 95% CI 0.01 to 4.24; 29 participants; 1 study). No clear evidence of a difference in adverse effects between the rutosides and placebo/no treatment groups was seen ('mild side effects' reported in 7/41 and 5/42 respectively). In the study comparing rutosides with ECS, 2/80 could not tolerate ECS and 6/80 stopped medication due to side effects. The study comparing rutosides with an alternative venoactive remedy did not comment on side effects AUTHORS' CONCLUSIONS: There was no evidence that rutosides were superior to the use of placebo or ECS. Overall, there is currently limited low-quality evidence that 'venoactive' or 'phlebotonic' remedies such as rutosides reduce symptoms of PTS. Mild side effects were noted in one study. The three studies included in this review provide no evidence to support the use of rutosides in the treatment of PTS.

Electrical calf muscle stimulation in patients with post-thrombotic syndrome and residual venous obstruction after anticoagulation therapy.

BACKGROUND: The aim of this study was to assess the impact of electrical calf muscle stimulation (EMS) on clinical and ultrasound outcomes in patients with post-thrombotic syndrome (PTS) and residual venous obstruction (RVO). METHODS: This was a prospective, comparative, non-randomized clinical trial involving patients who had completed a standard 6-month course of anticoagulation therapy for a first episode of unprovoked femoro-popliteal DVT and had signs of RVO in the affected veins and PTS as shown by a Villalta Score of >5. A blinded outcome assessor performed the ultrasound evaluations. A total of 60 patients in the age range from 40 to 86 years (mean 58.5±11.4) consisting of 38 men and 22 women were enrolled. They were divided into two groups of 30 participants each. Both groups (experimental and control) were treated by active walking, below-knee graduated compression stockings, and micronized purified flavonoid fraction. In the experimental group, EMS with «Veinoplus VI¼ device (three applications for 30 min every day) was also used. The patients were followed for 12 months with monthly DUS to reveal recurrent DVT and changes in RVO. The clinical criteria for treatment efficacy included changes in Villalta, VCSS and CIVIQ-20 scores. RESULTS: Recurrent DVT was found in seven of 30 patients in the control group and in zero of 30 patients in the experimental group (23.3% versus 0%, P=0.01). Through the follow-up period the degree of RVO decreased in all affected veins in both groups (P<0.01). The most significant changes were found in the popliteal vein; 60.8% decreased to 28.8% in the experimental group and 50.9% to 27.3% in the control group (P<0.01) with significant differences between the groups (P<0.01). VCSS, Villalta and CIVIQ-20 scores also significantly decreased in both groups (P<0.01). In the group with EMS, changes in the current parameters were more intensive (P<0.01). CONCLUSIONS: There is an ongoing process of deep vein recanalization during the 12 months after anticoagulant therapy cessation. Use of EMS in PTS treatment allows for reduction of recurrent DVT rates, increase the speed of deep vein recanalization and leads to additional improvement in the clinical PTS outcomes.

Considerations for Systemic and Topical Treatment of Morganella morganii Septicemia Arising from Maggot Infestation.

INTRODUCTION: Live maggot infestation (myiasis) of wounds can present a host of ailments. Loosely associated with maggot excreta, Morganella morganii is a widespread, gram-negative rod bacterium commonly found in the intestinal tracts of humans. M morganii has been observed as being pathogenic, particularly in nosocomial and postoperative environments, as well as in immunosuppressed and elderly populations. CASE REPORT: Herein, the authors present a rare, previously unreported case of M morganii septicemia (as confirmed by positive blood culture), secondary to myiasis of the lower extremities. The patient was successfully treated with both systemic and topical interventions. Posttreatment examination revealed resolution of myiasis and negative blood cultures. CONCLUSIONS: Myiasis can be invasive, leading to severe systemic infection. In these cases, a broad-spectrum antibiotic combined with systemic and topical antiparasitic therapy should be considered.

[Clinical efficacy of electric stimulation of crural muscles in comprehensive treatment of post-thrombotic disease]. / Klinicheskaia éffektivnost' élektricheskoi stimuliatsii myshts goleni v kompleksnom lechenii posttromboticheskoi bolezni.

The purpose of the study was to evaluate clinical efficacy of electromyostimulation (EMS) of the crural muscles as part of comprehensive therapy for post-thrombotic disease in patients with residual venous obstruction in the femoropopliteal segment. We carried out a prospective comparative clinical study enrolling patients having endured a fist episode of clinically unprovoked venous thrombosis of the femoropopliteal segment and completed the standard 6-month course of anticoagulant therapy and presenting with ultrasonographic signs of complete recanalization of the proximal venous segments (stenosis of 20% and more from the vessel's initial diameter), as well as scoring 5 points and more by the Villalta scale. The study included a total of 60 patients (38 men and 22 women, mean age 58.5±11.4 years) subdivided into two groups consisting of 30 patients each. Patients of both the Study and Control Groups underwent comprehensive therapy including wearing a compression knee sock (23-32 mmHg), a course phlebotrophic drugs, and dosed walking (not less than 5,000 steps a day). The Study Group patients were additionally subjected to daily electrical stimulation of the crural muscles with the "Veinoplus VI" unit (three 30-minute sessions a day). The duration of the follow up amounted to 12 months. The criteria for assessing therapeutic efficacy were as follows: severity of the disease by the VCSS and Villalta scales, quality of life as assessed by the CIVIQ-20 questionnaire, and lack of relapses of the venous thrombus. Clinical and instrumental assessment of the patients' condition was carried out monthly, with the disease's severity and quality of life assesses each 6 months. Relapses of venous thrombosis were registered in 7 (23.3%) patients from the Control Group and were not observed in patients undergoing EMS (p=0.011). In 5 cases, thrombosis was asymptomatic and in 4 cases it was presented by reocclusion of the involved venous segments. Patients of the Study Group were found to have a decrease in the disease's severity, reflected in points: VCSS (9.9±1.6 - 7.8 ± 1.6 - 6.1±1.5 (p <0.0001)); Villalta scale (18.9±3.9 - 12.8±4.0 - 8.3±2.7 (p<0.0001)); CIVIQ-20 score (67.8±8.4 - 51.3±8.4 - 40.0±10.5 (p<0.001)). The Control Group patients showed a similar tendency for the disease's severity: 8.1±2.8 - 7.3±2.1 - 7.2±2.1 points by the VCSS (p=0.014); 12.7±6.7 - 10.9±5.6 - 10.2±5.4 points by the Villalta scale (p=0.002), but not for quality of life: 48.2±19.3 - 46.7±17.3 - 47.4±16.2 points by the CIVIQ-20 (p>0.05). On the background of using EMS, the alterations in the studied parameters were characterized by higher velocity and intensity (p<0.05). The use of electromyostimulation as part of comprehensive treatment for post-thrombotic disease makes it possible to efficiently eliminate both subjective and objective signs of venous insufficiency, improve patients' quality of life and decrease the risk for the development of relapsing venous thrombosis.

A randomised controlled trial comparing venous stenting with conservative treatment in patients with deep venous obstruction: research protocol.

INTRODUCTION: Deep venous obstruction (DVO) has a great impact on quality of life (QoL) comparable to angina pectoris or chronic pulmonary disease. Post-thrombotic scar formation and May-Thurner syndrome (MTS) are the most common causes of DVO. Conventional treatment of DVO focuses on reducing pain or leg swelling by use of (pain) medication and therapeutic elastic stockings. In the past, a venous bypass was offered in severe post-thrombotic cases, but this procedure showed bad clinical and patency outcomes. With the introduction of percutaneous angioplasty and dedicated venous stents new opportunities were created. Deep venous stenting has been shown to be effective in retrospective case series. However, there is no prior research in which QoL after interventional treatment is compared with QoL after conventional treatment. Currently, there is a debate about the true additional value of interventional treatment. We investigate whether those patients who are treated with stenting experience a change in short form 36 (SF-36) and the Veines-QoL/Sym questionnaires compared with conventionally treated patients. METHODS AND ANALYSIS: This is a randomised trial comparing conservative deep venous management to interventional treatment. A total of 130 patients with post-thrombotic syndrome (PTS) or MTS, eligible for interventional percutaneous treatment, who did not have previous deep venous intervention will be included. Patients will be randomised to conservative treatment or venous stenting and stratified for the PTS or MTS subgroup. Conservative treatment consists of either one or a combination of pain medications, manual lymphatic drainage, compression stockings and regular post-thrombotic anticoagulant therapy.The primary outcome is the QoL change after 12 months compared with baseline QoL. Secondary outcomes are QoL changes at 6 weeks, clinical assessment of DVO, recurrence rate of deep venous thrombosis at 6 weeks and 12 months, and the total amount of working days lost. Intervention-specific outcomes include complications and patency. ETHICS AND DISSEMINATION: The protocol is approved by the Medical Ethics Committee of Academisch ziekenhuis Maastricht/Universiteit Maastricht, The Netherlands (protocol number NLNL55641.068.15 / METC 161008).We aim to publish the results of this study in a peer reviewed journal and present our findings at national or international conferences. TRIAL REGISTRATION NUMBER: The study protocol was registered at www.clinicaltrials.gov (registration number: NCT03026049) on 17 January 2017.

Combination of factor Xa inhibition and antiplatelet therapy after stenting in patients with iliofemoral post-thrombotic venous obstruction.

OBJECTIVES: Studies addressing optimal postprocedural pharmacological management after endovascular stenting of iliofemoral post-thrombotic venous obstruction are lacking. We report our early clinical experience with a combination of rivaroxaban and clopidogrel in patients after iliofemoral post-thrombotic venous obstruction stenting. METHODS: Demographic, procedural, and follow-up data of nine patients (seven women; mean age of 32 ± 11 years) undergoing 10 procedures for iliofemoral post-thrombotic venous obstruction performed between August 2012 and January 2014 were retrospectively reviewed. After endovascular intervention, all patients were administered 20 mg rivaroxaban once daily (s.i.d.) and 75 mg clopidogrel s.i.d. or every second day depending on the individual drug responsiveness for at least six months. The adenosine diphosphate-induced platelet aggregation (platelet aggregation, in aggregation units × min) was assessed on a Multiplate analyzer. Patency was verified venographically at procedure end and was evaluated with duplex ultrasound in regular follow-ups. RESULTS: Iliofemoral venous flow was successfully re-established by percutaneous endovascular angioplasty and stent implantation in nine left-sided and one bilateral iliofemoral post-thrombotic venous obstruction. Under dual treatment strategy of rivaroxaban and clopidogrel with platelet aggregation control (median (range): 285 aggregation units × min (192; 402)), none of the patients experienced restenosis or stent thrombosis, respectively. After a median follow-up of 14 months (range: 6-26 months), the primary patency rate was 100% and no in-stent restenosis, stent occlusion or relevant minor or major bleeding occurred. CONCLUSION: Combined factor Xa inhibition and tailored antiplatelet therapy after stenting of iliofemoral post-thrombotic venous obstruction were safe and performed favorably in terms of vessel patency.

Rutosides for treatment of post-thrombotic syndrome.

OBJECTIVES: To determine the effectiveness (improvement or deterioration in symptoms) and safety of rutosides for treatment of post-thrombotic syndrome (PTS) in patients with DVT compared to placebo, no intervention, elastic compression stockings (ECS) or any other treatment. SEARCH METHODS: For this update the Cochrane Vascular Group Trials Search Co-ordinator searched the Specialised Register (last searched September 2015) and the Cochrane Register of Studies (CRS) (CENTRAL (2015, Issue 8)). Clinical trials databases were searched for details of ongoing and unpublished studies. SELECTION CRITERIA: Two review authors (JM and DNK) independently assessed studies for inclusion. Studies were included to allow the comparison of rutosides versus placebo or no treatment, rutosides versus ECS, and rutosides versus any other treatment. Two review authors (JM and SEY) extracted information from the trials. Disagreements were resolved by discussion. DATA COLLECTION AND ANALYSIS: Data were extracted using designated data extraction forms. The Cochrane risk of bias tool was used for all included studies to assist in the assessment of quality.

One study compared rutoside with placebo, one study compared rutosides with ECS and rutosides plus ECS versus ECS alone, and one study compared rutosides with an alternative venoactive remedy. Occurrence of leg ulceration was not reported in any of the included studies. There was a 29% odds of an improvement in PTS in the rutoside treated group versus placebo or no treatment, and lower rates of improvement in PTS in the rutoside treated group when compared with ECS, however these were statistically non-significant. Lower rates of improvement in PTS were shown in the rutoside treated group when compared with an alternative venoactive remedy. More PTS deterioration was shown in the placebo or no treatment group when compared with rutosides but this was not statistically significant. Compared with ECS, rutosides showed higher odds of PTS deterioration but this was also not statistically significant. One study reported on adverse effects showing higher odds of mild adverse effects in the rutoside treated group compared to placebo but this was not statistically significant. AUTHORS' CONCLUSIONS: There was no evidence that rutosides were superior to the use of placebo or ECS. Overall, there is currently limited and low or very low quality evidence that 'venoactive' or 'phlebotonic' remedies such as rutosides reduce symptoms of PTS. Mild side effects were noted in one study. The three studies included in this review provide no evidence for the use of rutosides in the treatment of PTS.

Efficacy of a short course of complex lymphedema therapy or graduated compression stocking therapy in the treatment of post-thrombotic syndrome.

Treatment options for established post-thrombotic syndrome (PTS) are limited. Complex lymphedema therapy (CLT), a non-invasive treatment that improves lymphatic flow, may have the potential to improve PTS. We conducted a single-center, investigator-blind, randomized controlled trial of 31 patients with a clinically established diagnosis of PTS and compared the efficacy of graduated compression stockings alone (30-40 mmHg) with CLT, a treatment that includes compression stockings, exercise, patient education, skin care and lymphatic drainage. Primary outcomes were the 1- and 3-month changes in PTS severity by the Villalta score and disease-specific quality of life using the VEINES-QOL (Venous Insufficiency Epidemiological and Economic Study Quality of Life) questionnaire. Analysis was by intent-to-treat. We found from a baseline average score of 9.9 points, CLT reduced mean PTS severity scores by -2.4 points (p=0.02) at the 1-month and -2.3 points (p=0.05) at the 3-month follow-up. Score reductions with stockings only were similar at -2.1 (p=0.03) and -3.3 points (p=0.03) at 1 and 3 months. The differences in score between treatments were not significant. Neither treatment significantly changed the VEINES-QOL score except in patients with severe disease. Patients with moderate to severe PTS derived the greatest benefit from either therapy and the two therapies differentially impacted PTS signs and symptoms. We found a short course of lymphedema therapy and compression stockings offer similar benefit in patients with PTS; however, larger studies are needed to further explore the potential use of CLT in PTS, particularly in patients with more severe disease.

Advances in the diagnosis and management of postthrombotic syndrome.

Postthrombotic syndrome (PTS) is a frequent long-term complication of deep vein thrombosis (DVT). Known risk factors include obesity, recurrent ipsilateral DVT, iliofemoral DVT, persistent symptoms one month after DVT diagnosis, and having subtherapeutic INRs greater than 50% of the time during the first few months on anticoagulant therapy. Other risk factors remain under investigation. The Villalta scale ranks the presence and severity of signs and symptoms of PTS. Preventive therapies include use of elastic compression stockings. Compression therapy is also used to treat PTS, in addition to wound care for associated venous ulcers, and herbal therapies for postthrombotic ulcers and edema. Though not well studied, there are surgical options for severe cases of PTS refractory to other treatments. Ongoing clinical trials should provide insight on risk factors, and interventions for PTS prevention and treatment. In particular, use of early thrombolysis for acute iliofemoral DVT to prevent PTS is currently being investigated.

[Complex treatment of patients with lympho-venous insufficiency of the lower limbs].

The article is concerned with the study of use of physical factors in the treatment of chronic lymphphleboid failure of lower limbs. As a result, it was able to show a significant positive dynamic under the complex approach of treating this disease. In patients with chronic lymphphleboid failure of lower limbs justified individual tactics, based on the use of a wide range of modern medicines, physical therapy techniques, therapeutic exercises, lymphatic massage of the lower limbs. This leads to early rehabilitation and improvement of quality of patients' life.
