polidocanol and Venous-Thrombosis

Postablation deep vein thrombosis (DVT) represents a potentially serious complication after Varithena polidocanol endovenous microfoam (PEM) ablation. The following primary outcomes were assessed: whether (1) adjunctive apixaban anticoagulation or (2) mechanical deep venous system (DVS) saline flushing could decrease saphenofemoral junction (SFJ) thrombus extension (postablation superficial thrombus extension [PASTE]) and/or DVT compared with compression alone, after great saphenous vein (GSV) PEM ablation.. Varithena 1% PEM ablation patients were randomized to (1) SFJ compression, (2) compression and DVS saline flushing, or (3) compression, DVS saline flushing, and 5 days of postprocedural 5 mg oral apixaban anticoagulation twice daily. Duplex imaging was obtained 7 to 10 days after PEM ablation and PASTE/DVT incidence (primary end point) was compared between groups at this time point.. We treated 304 limbs in 257 patients with PEM. Overall, 103 limbs received SFJ compression (group C, 33.8%), 101 received compression and deep venous flushing (group D, 32.9%), and 100 received compression, deep flush, and anticoagulation (group A, 33.2%). Mean ultrasound follow-up time was 9.7 days (all patients) with a primary GSV closure rate of 92.4%. SFJ PASTE (II-IV) occurred in 0.9%, 1.0%, and 0% (groups C, D, and A, respectively). DVT occurred in 16.7%, 14.7%, and 1.98% (groups C, D, and A; χ. (1) Neither adjunctive DVS flushing nor anticoagulation decreased clinically relevant SFJ PASTE (II-IV) incidence, which remained similarly low across all groups and ranged between 0% and 1%, regardless of adjunctive DVS flushing or anticoagulation. This rate was significantly lower than prior reports (2.3%-4.1%). (2) DVS flushing had no influence on the rate of DVT. Observed PEM-induced DVT incidence using SFJ compression alone or compression with DVS flushing (16.7% and 14.7%, respectively) was significantly higher than prior reports (2.5%-9.6%). This finding may relate to the greater extent of AK/BK GSV territory treated in the present study. (3) Five days of postprocedural oral apixaban anticoagulation, 5 mg given twice daily, significantly decreased DVT occurrence to 1.98%, compared with nonanticoagulated patients (16.7%). This finding is comparable with the DVT rates reported after endovenous thermal ablation (0.7-1.7%). (4) Postprocedural apixaban anticoagulation may have a significant preventive role in decreasing DVT occurrence after PEM ablation.

Current guidelines recommend injection of cyanoacrylate as first-line therapy to prevent gastric variceal rebleeding. The method still poses a risk of ectopic embolism, which possibly correlates with the volume of cyanoacrylate used. In this trial, we evaluated the short-term efficacy and safety of tissue adhesive injection combined with lauromacrogol for treating gastric varices.. Patients admitted to our hospital for variceal hemorrhage were enrolled and blindly randomized into two treatment groups: lauromacrogol group (lauromacrogol-cyanoacrylate-lauromacrogol) and lipiodol group (lipiodol-cyanoacrylate-lipiodol). Patient follow-up was 6 months. Primary outcome was rebleeds, and secondary outcomes were mortality, gastric varices eradication, and treatment-related adverse events.. Between March 6, 2013 and October 16, 2013, 96 patients met the criteria. Two cases were lost to follow-up, and all treated cases were successful. No procedural-related adverse events were observed in either group. Cyanoacrylate volumes used in the lauromacrogol group were significantly less than those of the lipiodol group (0.9 ± 0.5 vs 2.0 ± 1.2 mL, P = 0.000). Eleven patients developed upper gastrointestinal rebleeding, which did not show significant difference between groups. On multivaritate analysis, portal venous thrombosis and fever were potential risk factors of rebleeding. Treatment failure, complications, gastric varices obturation, and survival did not differ between the two groups.. Tissue adhesives combined with lauromacrogol is a safe therapeutic option for gastric varices, with comparably less cyanoacrylate volume used. Because of the small number of study patients, it cannot be proven to have better efficacy than without lauromacrogol. Multicenter studies with larger patient groups are necessary.

To evaluate outcomes among symptomatic patients with superficial chronic venous insufficiency treated with retrograde ultrasound-guided polidocanol endovenous microfoam 1% (PEM) or endovenous laser ablation (EVLA).. This study is a retrospective chart review from a single vein center between October 2013 and June 2019. Procedures were performed on 1070 patients with Clinical, Etiologic, Anatomic, and Pathophysiologic class 2 to 6 disease and symptomatic superficial venous reflux of the great saphenous vein or anterior accessory saphenous vein.. PEM was used for 550 procedures and patients were followed for 43 ± 13 months; EVLA was used for 520 procedures and patients were followed for 57 ± 18 months. After complete treatment, the elimination of reflux was documented in 93.5% (514/550) and 92.8% (482/520) of the PEM and EVLA procedures, respectively. During the follow-up period, 18% of patients treated with EVLA returned for additional treatment to address residual symptoms in the affected leg. In C6 patients treated with PEM, 69% of ulcers (11/16) healed in less than 1 month, compared with 5% of patients (1/21) treated with EVLA. In C4 patients with lesions, resolution of spontaneous bleeding was 100% in both groups. There were no neurological or cardiac adverse events in the PEM group. Minor complications included asymptomatic deep vein thrombosis (0.5%), one common femoral vein thrombus extension, and superficial venous thrombosis (4%) in the PEM group and asymptomatic deep vein thrombosis (0.8%) and two endovenous heat-induced thromboses in the EVLA group.. PEM is comparable in safety and efficacy with EVLA for the treatment of saphenous reflux and associated symptoms. PEM was an effective intervention for most patients with C6 disease. Closure rates in both groups were maintained 36 months after treatment.

Thrombus extension into the deep venous system following superficial vein chemical ablation with Varithena polidocanol microfoam has been reported. The objective of this study was to assess the effect of intraoperative improved techniques during treatment for patients with symptomatic varicose veins and their impact on extension of thrombus into deep veins.. A retrospective review of a prospectively maintained database was performed. All patients who underwent endovenous chemical ablation with polidocanol microfoam (Varithena, Boston Scientific, Marlborough, Mass) for symptomatic superficial axial and tributary vein reflux were identified. Patients had postoperative duplex (48-72 hours) scanning after the procedure; those who did not adhere to the recommended follow-up were excluded. Demographic data, CEAP Classification, Venous Clinical Severity Score, procedure details, and follow-up data were abstracted.. Between April 2018 and August 2020, 157 limbs in 122 patients were treated with Varithena microfoam; 129 limbs in 99 patients met our inclusion criteria. Veins treated included the great saphenous vein (n = 89), anterior accessory saphenous vein (n = 15), small saphenous vein (n = 14), and tributary veins (n = 56). Adjunctive techniques during treatment included intraoperative elevation of the limb to greater than 45°, ultrasound mapping and digital occlusion of large perforator veins, limitation of foam volume per session, injection of sterile saline before treatment, and compression of the limb in the elevated position. The preoperative Venous Clinical Severity Score was 11.4 and decreased after treatment to 9.7. The immediate closure rate was 95% with 81% overall symptomatic relief at last follow-up. The mean follow-up was 113.5 days for the entire cohort; two limbs (1.5%) required postoperative anticoagulation for thrombus extension into the deep venous system (common femoral vein n = 1; popliteal vein n = 1) postoperatively for a mean of 22 days. Both resolved with anticoagulation. One asymptomatic limb developed a femoral vein deep venous thrombosis and one symptomatic late deep venous thrombosis was noted 4 months after the procedure. Postoperative pain and phlebitis were reported in 15.6% and 14.8% of patients, respectively, and all had resolved at last follow-up. No pulmonary emboli were noted and no neurologic or visual adverse events were recorded.. Adjunctive techniques during microfoam ablation decreased thrombotic complications in our series compared with those reported in earlier phase III clinical trials. Excellent early closure and symptomatic improvement were also noted. Endovenous microfoam ablation with Varithena is a safe and effective nontumescent, nonthermal alternative to laser and radiofrequency ablation.

To evaluate the incidence and clinical relevance of silent nontarget occlusion (NTO) of superficial and deep veins occurring after ultrasound-guided foam sclerotherapy (UGFS) that can be detected by serial duplex ultrasound scan (DUS).. This retrospective analysis evaluated the medical records of patients treated with UGFS at a private clinic in Moscow, Russia from 2015 to 2017. All patients underwent serial DUS at 1 to 2 weeks and 1, 3, 6, and 12 months after UGFS.. During the observation period, 268 patients were treated with UGFS, using physician compounded polidocanol foam 257 lower limbs of 196 patients (73%) with varicose veins who underwent DUS at 1 to 2 weeks after the last session of UGFS (inclusion time-point): 139 women and 57 men (mean age: 44.2 ± 12.2 years) with the following CEAP clinical class distribution: C2, 74.0%; C3, 20.0%; C4, 4.5%; and C5, 1.5%. NTO at the inclusion time-point occurred in 60 limbs (23.3%) of 57 patients (28.5%) and was symptomatic only in three limbs (1.2%). Most occlusions were localized in the untreated great saphenous vein trunk (. The frequency of nontarget vein occlusion after UGFS revealed by serial DUS may be as high as 23.3%. These occlusions tend to resolve within six months and are not associated with symptomatic VTE.

Although foam sclerotherapy to varicose veins is now a popular treatment because of its high efficacy and safety, some neurologic complications have recently been reported. Presently, the effectiveness and safety of intravenous recombinant tissue-type plasminogen activator therapy to stroke following foam sclerotherapy remain unclear. Here, we report the case of a 68-year-old woman whose ischemic symptoms following foam sclerotherapy were treated by intravenous recombinant tissue-type plasminogen activator. After she was admitted, the venous thrombosis in her right soleus vein and a patent foramen ovale causing the right-to-left shunt were revealed. Thus, we diagnosed the ischemic symptoms were due to paradoxical embolism following foam sclerotherapy. After intravenous recombinant tissue-type plasminogen activator therapy, there was no complication and the outcome was good. Our case suggests the effectiveness and the safety of intravenous recombinant tissue-type plasminogen activator therapy to paradoxical embolism following foam sclerotherapy.

We evaluated the effectiveness of pelvic vein embolization with aethoxysclerol in aero-block technique for the treatment of impotence due to venous leakage in men using sildenafil for intercourse. The aim of the procedure was to reduce the use of sildenafil.. A total of 96 patients with veno-occlusive dysfunction, severe enough for the need of PDE5 inhibitors for vaginal penetration, underwent pelvic venoablation with aethoxysclerol. The mean patient age was 53.5 years. Venous leaks were identified by Color Doppler Ultrasound after intracavernous alprostadil injection. Under local anesthesia a 20-gauge needle was inserted into the deep dorsal penile vein. The pelvic venogram was obtained through deep dorsal venography. Aethoxysclerol 3% as sclerosing agent was injected after air-block under Valsalva manoeuver. Success was defined as the ability to achieve vaginal insertion without the aid of any drugs, vasoactive injections, penile prosthesis, or vacuum device. Additionally, a pre- and post- therapy IIEF score and a digital overnight spontaneous erections protocol (OSEP) with the NEVA™-system was performed.. At 3 month follow-up 77 out of 96 patients (80.21%) reported to have erections sufficient for vaginal insertion without the use of any drug or additional device. Four (4.17%) patients did not report any improvement. Follow up with color Doppler ultrasound revealed a new or persistent venous leakage in 8 (8.33%) of the patients. No serious complications occurred.. Our new pelvic venoablation technique using aethoxysclerol in air-block technique was effective, minimally invasive, and cost-effective. All patients were able to perform sexual intercourse without the previously used dosage of PDE5 inhibitor. This new method may help in patients with contra-indications against PDE5 inhibitors, in patients who cannot afford the frequent usage of expensive oral medication or those who do not fully respond to PDE5-inhibitors.

Refluxing perforators contribute to venous ulceration. We sought to describe patient characteristics and procedural factors that (1) impact rates of incompetent perforator vein (IPV) thrombosis with ultrasound-guided sclerotherapy (UGS) and (2) impact the healing of venous ulcers (CEAP 6) without axial reflux.. A retrospective review of UGS of IPV injections from January 2010 to November 2012 identified 73 treated venous ulcers in 62 patients. Patients had no other superficial or axial reflux and were treated with standard wound care and compression. Ultrasound imaging was used to screen for refluxing perforators near ulcer(s). These were injected with sodium tetradecyl sulfate or polidocanol foam and assessed for thrombosis at 2 weeks. Demographic data, comorbidities, treatment details, and outcomes were analyzed. Univariate and multivariable modeling was performed to determine covariates predicting IPV thrombosis and ulcer healing.. There were 62 patients (55% male; average age, 57.1 years) with active ulcers for an average of 28 months with compression therapy before perforator treatment, and 36% had a history of deep venous thrombosis and 30% had deep venous reflux. At a mean follow-up of 30.2 months, ulcers healed in 32 patients (52%) and did not heal in 30 patients (48%). Ulcers were treated with 189 injections, with an average thrombosis rate of 54%. Of 73 ulcers, 43 ulcers (59%) healed, and 30 (41%) did not heal. The IPV thrombosis rate was 69% in patients whose ulcers healed vs 38% in patients whose ulcers did not heal (P < .001). Multivariate models demonstrated male gender (P = .03) and warfarin use (P = .01) negatively predicted thrombosis of IPVs. A multivariate model for ulcer healing found complete IPV thrombosis was a positive predictor (P = .02), whereas a large initial ulcer area was a negative predictor (P = .08). Increased age was associated with fewer ulcer recurrences (P = .05). Predictors of increased ulcer recurrences were hypertension (P = .04) and increased follow-up time (P = .02). Calf vein thrombosis occurred after 3% (six of 189) of injections.. Thrombosis of IPVs with UGS increases venous ulcer healing in a difficult patient population. Complete closure of all IPVs in an ulcerated limb was the only predictor of ulcer healing. Men and patients taking warfarin have decreased rates of IPV thrombosis with UGS.

The aim was to explore the current experience and practice of vascular surgeons in the United Kingdom and Ireland regarding foam sclerotherapy for varicose veins.. A postal questionnaire was sent to 609 members of the Vascular Society of Great Britain and Ireland.. There were 281 responses (47%). Seventy surgeons (25%) used foam sclerotherapy. Most use it selectively; few (29%) offer it to all patients. It was more likely to be used for recurrent varices (71%), in older patients (61%) and for smaller non-saphenous varices (67%). The majority of surgeons (69%) used sodium tetradecyl sulphate and up to a maximum of 10-12 ml of foam. The majority used ultrasound guidance (95%), leg elevation (69%) and direct pressure over the saphenofemoral or saphenopopliteal junction during injection (63%). Eighty per cent used compression bandaging after treatment, usually for 7 days (44%). Ninety percent advised compression stockings, usually Class II (64%) for 14 days (39%). Serious complications were few, but eleven surgeons had seen a deep vein thrombosis, two had seen a patient with a stroke and one a transient ischaemic attack.. Foam sclerotherapy was used by a quarter of surgeons who replied to the survey. Aspects of technique varied considerably and studies to determine optimal techniques are needed. Serious complications with the technique were rare.
