Vascular sclerosing effects of bleomycin on cutaneous veins: a pharmacopathologic study on experimental animals

Abstract: Background: Varicose veins and the complications of venous disease are common disorders in humans. Objective: To study the effects of bleomycin as a potential new sclerosing agent and its adverse events in treating varicose veins. Methods: Bleomycin-loaded liposomes 0.1ml was injected in the dorsal ear veins of white New Zealand rabbits. Sodium tetradecyl sulfate was used as a positive control. Normal saline was used as negative control. The blood vessels of the treated ears were photographed before and at one hour and two, eight and 45 days after treatment. Biopsies from the treated areas were obtained for histological examination. Blood samples were collected to determine any possible toxicity. Results: Bleomycin by itself was ineffective; therefore, liposomes were used as a vector to deliver bleomycin to the vein lumen. Subsequently, bleomycin started showing its sclerosing effects. Toxicity monitoring showed no apparent hematologic, pulmonary, hepatic or renal toxicities. This study revealed that bleomycin induced vasculitis, which led to vascular occlusion, which was observed on day 1 and day 8. No bleomycin-related injury was noted by histopathological examination of lung sections. The calculation of the lung/body weight coefficient indicated that edema was present in the experimental groups compared with the negative and positive controls. Study limitations: Relatively small number of experimental animals used. Conclusions: This study showed that bleomycin-loaded liposomes were able to induce vasculitis and vascular occlusion without any toxicity or complications. It might be useful, hence, to treat patients suffering from Varicose veins and other ectatic vascular diseases with this agent.

Efficacy and Safety of Balloon-Occluded Retrograde Transvenous Obliteration with Sodium Tetradecyl Sulfate Liquid Sclerotherapy

OBJECTIVE: To evaluate the efficacy and safety of balloon-occluded retrograde transvenous obliteration (BRTO) with sodium tetradecyl sulfate (STS) liquid sclerotherapy of gastric varices. MATERIALS AND METHODS: Between February 2012 and August 2014, STS liquid sclerotherapy was performed in 17 consecutive patients (male:female = 8:9; mean age 58.6 years, range 44-86 years) with gastric varices. Retrograde venography was performed after occlusion of the gastrorenal shunt using a balloon catheter and embolization of collateral draining veins using coils or gelfoam pledgets, to evaluate the anatomy of the gastric varices. We prepared 2% liquid STS by mixing 3% STS and contrast media in a ratio of 2:1. A 2% STS solution was injected into the gastric varices until minimal filling of the afferent portal vein branch was observed (mean 19.9 mL, range 6-33 mL). Patients were followed up using computed tomography (CT) or endoscopy. RESULTS: Technical success was achieved in 16 of 17 patients (94.1%). The procedure failed in one patient because the shunt could not be occluded due to the large diameter of gastrorenal shunt. Complete obliteration of gastric varices was observed in 15 of 16 patients (93.8%) with follow-up CT or endoscopy. There was no rebleeding after the procedure. There was no procedure-related mortality. CONCLUSION: BRTO using STS liquid can be a safe and useful treatment option in patients with gastric varices.

Utility of sodium tetradecyl sulfate sclerotherapy from benign oral vascular lesion / 대한악안면성형재건외과학회지

BACKGROUND: Hemangioma and vascular malformation are benign vascular lesions that often occur in cephalic and cervical region. Currently, surgical resection, laser therapy, angiographic embolization, use of steroids, and sclerotherapy are used as treatments. CASE PRESENTATION: This study reports three cases of benign vascular lesions that are remarkably treated by sodium tetradecyl sulfate (STS) injection, of which occurred in oral cavity and around the mouth. Three percent of STS was diluted with 0.9 % of normal saline, and it was injected to the lesion site at least once. The result of treatment was evaluated based on clinical findings. CONCLUSION: Surgical treatment of hemangioma and vascular malformation occurred in oral cavity is not normally used because of esthetic issues and potential hemorrhage. On the other hand, sclerotherapy using STS is an effective therapy compare to surgical treatment. Despite the number of STS injection was different for each patient, all three patients had reached satisfactory level through the treatment with gradual diminution of lesions.

Sclerotherapy using 1% sodium tetradecyl sulfate to treat a vascular malformation: a report of two cases

Vascular malformations are the most common congenital and neonatal vascular anomalies in the head and neck region. The demand for simple and esthetic vascular malformation treatments have increased more recently. In this study, two patients that were diagnosed with venous malformations were treated with sodium tetradecyl sulfate as a sclerosing agent. Recurrence was not found one year after the surgery. This article gives a brief case report of sclerotherapy as an effective approach to treat vascular malformations in the oral cavity.

The Therapeutic Effect of 1% Sodium Tetradecyl Sulfate Sclerotherapy of Pyogenic Granuloma / 대한피부과학회지

BACKGROUND: For the treatment of pyogenic granuloma (PG), surgical excision, electrocautery, and laser therapy have been employed, apart from other methods. Sodium tetradecyl sulfate (STS) sclerotherapy, as a minimally invasive treatment for vascular lesion, is frequently used for vascular malformations with considerable efficacy and safety. However, there have been a few reports about its use in the treatment of PG. OBJECTIVE: This study was conducted to evaluate the efficacy, recurrence, and side effects of sclerotherapy using 1% STS in the treatment of PG. METHODS: We evaluated 72 patients with PG who were treated with 1% STS from January 2008 to December 2014. Sclerotherapy using 1% STS was performed by "blind" intralesional injection without the aid of imaging such as ultrasonography. The results were evaluated by physical examination, photographic evaluation, and the patient's subjective satisfaction, and then they were classified into 3 groups: complete remission, partial remission, and no change. Recurrence and side effects were also evaluated. RESULTS: Complete remission of PG was achieved in 65 (90.3%) of patients after 1.23 average sessions (range, 1~5 sessions). The remaining patients showed partial remission, with no instances of the treatment resulting in no change. One case of recurrence (1.4%) from partial remission group was seen after 3 months. Clinically, side effects such as pain, tenderness, hyperpigmentation, ulcer, numbness, scarring, and hair loss patches were noted in 18 (25%) patients, but these were all mild and transient. CONCLUSION: 1% STS sclerotherapy can be recommended as an effective therapeutic modality for the treatment of PG with insignificant adverse effects and low recurrence rate.

Induction of Contraception by Intraepididymal Sclerotherapy

PURPOSE: The objective of the present study was to evaluate the efficacy of a sclerosing solution for inducing epididymal occlusion in male rats. MATERIALS AND METHODS: Male Sprague-Dawley rats were divided into two groups: an injection group (n=20) and control group (n=20). Before injecting the sclerosing agent, seminal vesiculectomy and sperm identification using electrostimulation were performed in all of the rats. In the injection group, 0.2 mL of 0.1% sodium tetradecyl sulfate solution was injected into the epididymis. In the sham group, only the identification of the epididymis was performed. At 4 and 12 weeks after the injection, semen was collected by electrostimulation and evaluated to assess the contraceptive effect. Epididymis was evaluated by hematoxylin and eosin (H&E) staining. RESULTS: After 4 and 12 weeks, semen collection was performed in the two groups. Sperms were not observed in the injection group, while there was no change in the sperms in the sham group. H&E staining showed the obstruction of epididymal tubules and an accumulation of inflammatory cells in the injection group. CONCLUSIONS: This study showed that the sclerosing agent induced sterilization in male rats. This result suggests that the injection method can replace vasectomy as a contraceptive method. However, a further study of large animals and a clinical study are needed. Further, the long-term effectiveness of this method needs to be studied.

Sclerotherapy in the management of varicose veins and its dermatological complications.

Background: Varicose veins and its dermatological complications like stasis dermatitis, ulcers, spontaneous bleeding are commonly seen in the dermatology clinics. Surgery has been the most often used treatment for varicose veins. Sclerotherapy refers to introduction of sclerosing solution into the varicose veins, which causes endothelial damage and subsequent fibrosis. Sclerotherapy is being practised extensively by dermatosurgeons in the west. However, there are no Indian studies which specifically evaluate the role of sclerotherapy in the management of varicose veins and its skin complications. Hence, this study aims to evaluate the efficacy of sclerotherapy in managing varicose veins and its complications. Aims: To study the safety and efficacy of sclerotherapy in the treatment of varicose veins and its dermatological complications. Methods: This is a prospective study involving 50 patients with varicose veins and its dermatological complications attending the dermatology out-patient department. The study was conducted over a period of 18 months. After thorough clinical, laboratory, and radiological evaluation, the patients were treated with sclerotherapy using Sodium Tetradecyl Sulphate of various concentrations depending on the vessel size. The patients were then followed up to look for disappearance of veins, healing of ulcers and eczema, and any complications.Results: Patients showed a good response to treatment with sclerotherapy. 70-80% of patients showed symptomatic improvement along with disappearance of veins and healing of eczema and ulcers. Most of the complications were minor, which resolved over a period of few weeks. Conclusion : Sclerotherapy is a simple, safe and effective procedure for the treatment of varicose veins and its dermatological complications. The procedure is particularly effective for smaller, early varicosities and also for residual veins after surgery. Hence we recommend more and more of our fellow dermatologists to take up this procedure, which can be an efficient tool to manage patients with varicose veins and its related complications.

Sclerotherapy of benign oral vascular lesion with sodium tetradecyl sulfate: cases report

Hemangioma and vascular malformation is a common vascular benign lesion in the head and neck region. The lesion is a congenital malformation observed in neonates. The treatment this lesion includes surgical excision, cryotherapy, selective embolization and treatment with sclerotic agents. We present three cases of benign oral vascular lesions treated with an intralesional injection of sodium tetradecyl sulfate. The lesions virtually disappeared after three sessions of sclerotherapy, leaving an inconspicuous scar. No side effects were observed. Sclerotherapy with sodium tetradecyl sulfate is effective in treating benign oral vascular lesions, and the use of the sodium tetradecyl sulfate provides alternative or support for surgical methods.

The Effect of 0.5% Sodium Tetradecyl Sulfate on a Venous Lake Lesion

BACKGROUND: A venous lake lesion is a venous ectasia that occurs on the exposed skin of elderly people. Although a number of therapies such as surgical excision, laser therapy, infrared coagulation, cryotherapy and sclerotherapy have been used to treat venous lakes, there is no guideline for treating this lesion. OBJECTIVE: The purpose of this study was to determine whether 0.5% sodium tetradecyl sulfate (STS) is effective for the treatment of venous lake lesions. METHODS: Twelve patients with venous lake lesions were enrolled In this study. After proper antiseptic preparation, 0.5% STS was slowly injected into each subject's lesion, and this was followed by immediate compression for 10 minutes. RESULTS: After treatment, all of the patients' lesions cleared completely. The average number of treatments was 2.15+/-1.28. Two patients experienced mild side effects such as light pain and paresthesia, and these soon disappeared. There were no serious side effects reported during treatment. The mean follow up period was 29.58+/-13.48 months. CONCLUSION: We have demonstrated that sclerotherapy with 0.5% STS was quite effective for treating venous lake lesions, and this treatment caused no serious adverse effects.

Sclerotherapy in the Treatment of Congenital Venous and Lymphatic Malformation: Efficacy and Safety with Long-term Follow-up / 대한피부과학회지

BACKGROUND: Surgical excision and alcohol sclerotherapy have been used to treat congenital vascular malformations (CVM) with a significant success rate but the methods have also left marked morbidity. The alternative, sclerotherapy using ordinary sclerosants, although resulting in trivial complications, has a relatively low cure rate and is rarely used in Korea for CVM management. OBJECTIVE: To evaluate the effects and side effects of sclerotherapy using ordinary sclerosants such as polidocanol (POL) and sodium tetradecyl sulfate (STS) for the treatment of CVM of a venous and lymphatic type. METHODS: To confirm the long-term effects and safety with at least a 3-year follow-up, we chose a total of 26 patients who had undergone sclerotherapy between 2000 to 2004. There were 22 venous malformations (VMs) and 4 lymphatic malformations (LMs) which were rather small and superficial, not beyond muscular fascia. Sclerotherapy using POL and STS was performed by blind intraluminal and/or intralesional injection without the aid of imaging methods such as ultrasound examination. The results were evaluated by the patients' subjective satisfaction, physical examination, comparison of photographs and/or radiological examinations, then they were classified into 4 groups; excellent (improvement >75%), good (50~75%), fair (25~49%) and poor (<25%). RESULTS: Twenty two VMs comprised 14 in the excellent group (66.7%), 6 in the good group (25.0%), 1 in the fair group (4.2%) and 1 in the poor group (4.2%). Two LMs of macrocystic type revealed excellent results but the other two showing microcystic type revealed poor results. The dose of sclerosant was 0.1 to 2 ml in every session and a total of 1 to 6 sessions (average: 2.2) were performed. Only one VM showed hyperpigmentation as a side effect. CONCLUSION: Sclerosants for ordinary varicose vein eradication can be used on the treatment of small and superficial venous malformations and macrocystic-lymphatic malformations with relative efficacy and safety.

Three Cases of Digital Mucous Cyst Treated with Sodium Tetradecyl Sulfate Sclerotherapy / 대한피부과학회지

A digital mucous cyst is a benign, non-inflammatory disease frequently observed on the dorsal aspect of the fingers and toes. Multiple punctures with extraction of the cyst contents and intralesional steroid injections are the suggested treatments. However, this approach has shown a high failure and recurrence rate. Cryotherapy has had a better success rate but it is a more painful procedure. Surgical excision of the communicating tract between the cyst and joint has been reported to have the highest cure rate but it requires highly skilled surgery, and the surgery has the risk of severe complications including contractures of the joints and acquired nail deformity. We report three patients with digital mucous cysts treated by sclerotherapy without complications.

Endoscopic abnormalities in the oesophagus after variceal sclerotherapy--a long-term follow up study.

Endoscopic sclerotherapy is a well-established treatment modality for oesophageal varices. Various local, regional and systemic complications occur after sclerotherapy. Altered endoscopic appearances of the oesophagus have been observed on follow-up of patients after sclerotherapy. 171 consecutive patients with extra-hepatic portal venous obstruction on follow up after achieving variceal eradication by sclerotherapy during the period from January 2004 to June 2005 were enrolled in this study. The oesophagus was closely observed for mucosal abnormalities and the endoscopic findings were recorded. Out of 171 patients, 95 (55.5%) patients had no specific endoscopic changes in the oesophagus. The most common finding was mucosal neovascularization which was seen in 56 (32.7%) patients. Oval or oblong depressed areas were seen in 41 (23.9%) patients. Mucosal tags and polypoidal lesions were seen in 37 (21.6%) patients. 25 (15.6%) patients had stenosis of the lower oesophagus and 3 (1.7%) patients had mucosal bridges. On multivariate analysis, these abnormal endoscopic findings in the oesophagus correlated with the total volume of sclerosant injected when compared with those patients without similar findings on endoscopy (p value < 0.001). Endoscopic sclerotherapy leads to various abnormalities at the injection sites like neovascularization, oval or oblong depressed areas, mucosal tags, polypoidal lesions, stenosis and mucosal bridges. Endoscopic abnormalities correlated with the total volume of sclerosant used. The long-term significance of these changes is not known at present and further follow-up studies will be required.

Therapeutic Effects of Sclerotherapy of Venous Lake on the Lip / 대한피부과학회지

BACKGROUND: Although venous lake is asymptomatic, treatment is usually performed for cosmetic purposes or to prevent bleeding after trauma. The treatment is diverse and includes surgical excision, compression and cryotherapy. Above all, sclerotherapy is a useful and effective procedure for the treatment of venous lake on the lip. OBJECTIVE: This study was undertaken to assess the effectiveness and complications of the sclerotherapy of venous lake on the lip. METHODS: Fifteen lesions from eleven patients with venous lake on the lip were treated with sclerotherapy using sodium tetradecyl sulfate, detergent sclerosant. According to the size of lesions, the volume of infused solution was varied and the effectiveness of treatment was evaluated after four weeks. RESULTS: After a single treatment, fourteen of the fifteen lesions(93.3%) were cleared completely. The remaining lesion was treated one additional time. There were no reported complications during treatment. CONCLUSION: Sclerotherapy is highly effective and safe for the treatment of venous lake on the lip and may be a promising treatment option.

Therapeutic Effect of Sclerotherapy on Venous Malformations / 대한피부과학회지

BACKGROUND: Although surgical excision is the standard method for the treatment of venous malformations, this procedure often leads to massive bleeding and cosmetic problems. Sclerotherapy for venous malformations has recently been reported, whereas sclerotherapy for varicose veins, leg telangiectasias and hemorrhoids has well been established. PBJECTIVE: To assess the usefulness of sclerotherapy for venous malformations. METHOD: Fourteen patients who had venous malformation were treated with sclerotherapy using sodium tetradecyl sulfate (Thromboject(R), Omega Laboratories, Ltd., Montreal, Canada). Clinical efficacy was evaluated by physical examination and comparison of photographs. RESULTS: In patients with venous malformations, 71.4% of the eases showed moderate to marked improvement. Side effects were noted in 6 patients, however, they were trivial and transient and no treatment was needed. CONCLUSION: Sclerotherapy can be recommended as an effective method for the treatment of venous malformations. It has milder and fewer side effects than other treatment modalities, and it also yields superior cosmetic results.

Two Cases of Venous Lake Treated with a Sclerosing Agent / 대한피부과학회지

Venous lakes are small, dark blue, slightly raised, soft lesions occurring on the exposed skin of an elderly person. The face, ears, lips, neck, forearms and backs of hands are common sites. Histopathologic findings show either one greatly dilated space or several interconnected dilated spaces filled with erythrocytes and lined by a single layer of flattened endothelial cells in the upper dermis. We report two cases of venous lake treated with sodium tetradecyl sulfate (STS) which is one of sclerosing agents. The lesions was almost disappeared and no side effects were observed. The two cases showed no recurrence.

A Case of Glomangioma Treated with Sclerotherapy / 대한피부과학회지

Glomangioma is a kind of glomus tumor showing components of glomus cells and blood vessels. A 12-year-old female visited our department due to a tender 8 X 7 cm sized plaque formed by multiple conglobated nodules that had been growing on the left thigh since her birth. Histopathological findings showed dilated, thin walled vascular spaces surrounded by several layers of glomus cells, compatible with glomangioma. Glomangioma has been treated with surgical excision, laser, and sclerotherapy. We treated her by sclerotherapy in considering size and depth of the lesion. After second sclerotherapy with 1% sodium tetradecyl sulfate, the tender lesion almost disappeared. Sclerotherapy was effective to treat large glomangioma with good cosmetic outcome.
