BACKGROUND
Over the past decades, multiple approaches to aspiration sclerotherapy of large symptomatic hepatic cysts have been investigated. However, comparative data are scarce.
OBJECTIVE
The objective of this article is to compare cyst reduction, symptomatic relief, and adverse events between ethanol sclerotherapy and polidocanol sclerotherapy.
METHODS
This retrospective study included adults having a symptomatic hepatic cyst treated at a European tertiary referral center with ethanol sclerotherapy (Center 1) or polidocanol-sclerotherapy (Center 2). We compared cyst diameter reduction (%) and symptom improvement (yes/no) within 12 months' post-treatment between centers using multivariate regression analyses adjusted for confounding factors. Finally, we compared adverse events using Fisher's exact test.
RESULTS
We included 71 patients from Center 1 and 66 patients from Center 2 (median age 57 years; 126/137 (92%) female). Cyst reduction was comparable between Centers 1 and 2: 37.5% (IQR 15.7-61.0%) versus 44.2% (IQR 24.6-60.5%), respectively ( = 0.35). Correspondingly, symptomatic relief was comparable: 30/53 (56.6%) versus 43/66 (65.2%), respectively ( = 0.88). Center 1 reported significantly more (11 versus 3; = 0.047) adverse events than Center 2.
CONCLUSION
We found comparable cyst reduction and symptomatic relief rates between ethanol- and polidocanol sclerotherapy, while adverse events occurred more often in the ethanol group. Prospective studies focused on clinical response are needed to further explore differences between approaches.

Review
This review of the literature aims to compare the etiology, the pathogenesis, the clinical diagnostics and the relevant treatment options of two different types of cystic bone lesions: the solitary bone cyst (SBC) and the aneurysmal bone cyst (ABC). Whereas the clinical symptoms and the radiographic appearance can be similar, the diagnostic pathway and the treatment options are clearly different. The solitary bone cyst (SBC) represents a tumor-like bone lesion, occurring most frequently in the humerus and femur in children and adolescents. Pain caused by intercurrent pathological fractures is often the first symptom, and up to 87% of the cysts are associated with pathological fractures. In the majority of cases SBCs can be treated conservatively, especially in the upper extremity. However, if a fracture is completely dislocated, joint affecting, unstable or open, surgical treatment is necessary. Pain under weight bearing or regaining the ability to mobilize after fracture timely can necessitate surgical treatment in SBCs affecting the lower extremity. Spontaneous resolution can be seen in rare cases. The aneurysmal bone cyst (ABC) is a benign, locally aggressive tumor that occurs in childhood and early adulthood. It usually affects the metaphysis of long bones but can also occur in the spine or the pelvis. ABC can be primary but also secondary to other bone pathologies. The diagnosis has to be confirmed by biopsy and histopathological examinations. With cytogenetic studies and the detection of specific translocations of the ubiquitin-specific protease (USP) 6 gene primary ABCs can be differentiated from secondary ABCs and other bone lesions. Among various modalities of treatment i.e. en bloc resection, intralesional curettage with adjuvants, embolization or the systemic application of denosumab, intralesional sclerotherapy using polidocanol is an effective and minimally invasive treatment of primary ABCs.

Review
BACKGROUND
Percutaneous treatment for primary aneurysmal bone cysts (ABCs) has been widely accepted. The study aimed to evaluate the efficacy of various sclerotherapy agents on patients with primary ABCs.
METHODS
A meta-analysis of relevant studies. A systematic search was conducted on five databases, resulting in the inclusion of 25 studies with different percutaneous agents.
RESULTS
A total of 729 patients with primary ABCs were included. Patients were administered with Ethibloc, doxycycline, embolization, alcohol, polidocanol, and calcitonin with methylprednisolone, respectively. Overall, 542 (74.3%) patients with ABCs had complete healing, 120 (16.4%) had partial healing, 44 (6%) had no-ossification or failure, and 26 (3.5%) had a recurrence. However, there was a total of 45 (6.1%) patients who had surgical curettage after sclerotherapy. Among the sclerotherapy agents, doxycycline showed highly effective results with minimal complications and recurrence, but it required multiple injections per patient. Ethibloc and embolization also proved to be highly effective with fewer injections required but had a higher rate of complications. Absolute alcohol, polidocanol, and calcitonin with methylprednisolone had similar efficacity and favorable success with fewer complications and fewer injections.
CONCLUSION
Percutaneous treatment showed promising results in treating primary ABCs. However, more robust research is needed to establish the best approach for sclerotherapy in clinical practice and to address the limitations of the current literature.

BACKGROUND
Highly operator-based injection therapy with vasosclerosing and anesthetic polidocanol is used for tendinopathies. This pilot-study evaluates the topical application of polidocanol gel.
METHODS
Prospective case series. 39 patients with tendinopathies (14 Achilles, 14 patella, 11 wrist extensors) with a symptom duration > 6 months were included. Polidocanol and static stretching were the therapy in the first 2 weeks, while static stretching was continuously performed for 6 months. Clinical outcome was evaluated with VISA-A, VISA-P and DASH Scores and sonographically with B-Mode (B-Mode), Power Doppler (PD) and Shearwave Elastography (SWE).
RESULTS
22 patients clinically improved (>+10 score points), 11 patients were without improvement (<+ 10) and 1 patient worsened during 6 months. The VISA-A Score increased in average 19 points from 56 to 75 (p< 0.01), VISA-P Score increased 13 points from 59 to 72 (p< 0,01) and the DASH-Score decreased 20 points from 40 to 20 (p< 0,01). SWE correlates better than B-Mode or PD with symptom improvement.
CONCLUSION
The combination of static training and topical polidocanol application seems to be successful in the treatment of tendinopathies. Further RCT studies need to evaluate the efficiency of topical polidocanol application. SWE is a more sensitive tool to describe symptom development than PD or B-Mode.

Review
Venous malformations are very commonly encountered in interventional radiologic practice. Indications for therapy are clearly defined based on the lesion's impact on patient's quality of life. Screening laboratory coagulation studies in patients with historical or lesion morphologic risk factors often reveal abnormal coagulation parameters consistent with localized intravascular coagulation or more severe coagulopathic states. These may require chronic or periprocedural medical management to avoid potentially life-threatening disseminated intravascular coagulation or other thromboembolic phenomena. Once a multidisciplinary decision to treat a venous malformation is made, one must decide between percutaneous and/or surgical techniques. Sclerotherapy with adjunctive stasis of efflux (STASE) techniques have become the mainstay of therapy for most venous malformations as they are well-tolerated and effective. STASE techniques work primarily by (i) the administration of sclerosant(s) exerting an inhibitory and/or endotheliocidal effect on venous malformation endothelium leading to thrombosis, involution, and fibrosis, and secondarily via adjunctive outflow occlusion using any combination of local compression, balloons, gelatin, coils, laser, radiofrequency, or adhesives to improve sclerosant penetration and dwell-time in the lesion. Adhesives alone can fill the lesion to facilitate surgical resection in some cases. Common sclerosants in modern practice include sodium tetradecyl sulfate, bleomycin, polidocanol, ethanol, and hypertonic saline. Most agents can be given directly in unmodified or "neat" form or can be mixed with a gas to form a sclerofoam or embolic such as gelatin to form a sclerogel. Choice and method of sclerosant delivery in each patient is based on the intraluminal lesion volume, architecture, vital structure proximity, agent toxicity, viscosity, and level of experience of the interventional radiologist with that particular agent. Multi-session STASE therapy usually reduces symptoms of chronic pain or mass with low risk of known complications of skin or nerve impairment, compartment syndrome, hemoglobinuria, deep venous thrombosis, or pulmonary phenomena.

OBJECTIVE
Mechanochemical endovenous ablation is a nonthermal method to ablate superficial incompetent veins. The aim of this paper was to assess short-term complications and 5-year follow-up outcomes.
METHODS
This is a retrospective single-center study of data collected prospectively. We treated, in an outpatient setting, 395 primary, symptomatic, unilateral, incompetent varicose saphenous veins. No patients were treated bilaterally in the same session. The majority were great saphenous veins (92.3%), and the others were small saphenous veins. Procedures were performed with a mechanochemical endovenous occlusion catheter (ClariVein endovenous occlusion catheter; Merit Medical, South Jordan, Utah) and polidocanol 2% in liquid form.
RESULTS
Follow-up was available for 329 patients treated between September 2012 and September 2017 with a mean follow-up time of 20 ± 18 months (range, 6-60 months). Technical success was achieved in 99.5%; in two patients, we were unable to complete the procedures because of vein spasm leading to catheter damage and inability to infuse the sclerosant. Follow-up was performed with clinical evaluation and duplex ultrasound scan at 1 week, 1 month, 6 months, and 1 year and then once every year. The overall survival rate free from recanalization was 92.4%. Anatomic success is 94% at 1 year, 91% at 2 years, 88% at 3 years, 88% at 4 years, and 84% at 5 years. The follow-up at 5 years includes 23 patients, 5 of whom presented with recanalization; moreover, in this series, in 36% of cases, the veins completely disappeared on duplex ultrasound scan.
CONCLUSIONS
The ClariVein catheter is associated with a good occlusion rate, comparable with other techniques including thermal techniques, without major complications.

BACKGROUND
Cesarean scar pregnancy (CSP) refers to the implantation and growth of the gestational sac at a uterine scarring site due to a previous cesarean section. The effects of CSP on subsequent fertility have emerged as a clinical issue of importance in gynecology and obstetrics in China owing to the increasing rate of cesarean section over the past 30 years in combination with the abolition of the national family planning policy, allowing for subsequent pregnancies. Therefore, we aimed to investigate the effects of CSP treatment on subsequent fertility and pregnancy outcomes.
METHODS
The study consecutively enrolled 499 women treated for CSP at Taizhou Hospital between January 2009 and December 2018. The study outcomes were the rate of secondary infertility and pregnancy outcomes. Clinical information was collected at the time of admission for CSP treatment. Information on subsequent fertility and pregnancy outcomes was collected via telephonic follow-up.
RESULTS
Among the 499 women who met the inclusion criteria for CSP, 48 were lost to follow-up. Most women (74.9%, 338/451) did not express the desire for a subsequent pregnancy after CSP treatment. Among the 113 women who initially desired a subsequent pregnancy, 62 finally abandoned fertility plans. Among the 51 women who pursued pregnancy, 48 pregnancies were recorded in 43 women, infertility secondary to CSP treatment was identified in 15.7% (8/51) of women, and 60.8% (31/51) of women achieved full-term pregnancy, with placenta accreta spectrum identified in two women, one requiring a hysterectomy during cesarean section due to massive bleeding. Among the 16 women treated with uterine artery embolization combined with uterine aspiration and 18 women treated by ultrasound-guided local lauromacrogol injection combined with uterine aspiration, a successful full-term pregnancy rate of 68.8% (11/16) and 88.9% (16/18), respectively, was achieved. There were five cases of recurrent CSP among all 76 pregnancies (6.6%).
CONCLUSION
Over a long-term follow-up of women after CSP treatment, a high successful fertility rate was identified, with also an increased CSP recurrence rate. Uterine artery embolization combined with uterine aspiration and ultrasound-guided local lauromacrogol injection combined with uterine aspiration showed high rates of successful post-treatment fertility and pregnancy.

BACKGROUND
Aneurysmal bone cysts (ABC) are benign but locally aggressive lesions. The treatment of ABC has evolved over the years, but curettage with or without local adjuvants still represents the standard. Less invasive methods such as embolization, sclerotherapy or RANKL inhibitors (Denosumab) are also established. The aim of this study was to report and compare the results of a series of patients mainly treated with curettage with and without subsequent phenolization.
METHODS
65 patients with the unequivocal diagnosis of primary ABC were treated. 61 of them were located within the bone whereas 4 patients had an ABC of the soft tissues. All patient were treated surgically by means of curettage with or without adjuvants, resection, or with minimally invasive methods such as Polidocanol injections, embolizations or Denosumab treatment. In total 80 procedures had been performed.
RESULTS
Our patients had a mean age of 25.3 ± 16.0 years, ranging from 4 to 74 years. The most common skeletal locations were the pelvis in 23%, the femur in 18%, the tibia in 16% and the spine in 10%. Six lesions were resected and showed no recurrence. 5 patients were treated with polidocanol injections ( = 3) or embolization plus systemic treatment with Denosumab ( = 2). With embolization and Denosumab both patients showed stable disease and required no further treatment. Polidocanol injections resulted in stable disease with no further treatment required in one patient and in subsequent curettage with adjuvant phenolization in two other patients.In 54 initial curettages 21 were performed with adjuvant phenolization. In this group, 16 lesions healed (76%), 3 showed persistent disease and 2 patients had a local recurrence (9%). Out of 33 patients without phenolization 21 (64%) healed, 3 showed stable persistent disease and 9 (27%) experienced a recurrence. In total we performed 66 curettages, 27 with and 39 without adjuvant phenol treatment. Resolution was achieved in 19 (70%) and 25 (64%) of cases. respectively. Persistent disease was evident in 5 cases each and recurrence in 3 and 9 cases, respectively (n.s.).
CONCLUSION
Curettage is still the standard of treatment for ABC. Local recurrence does not depend on the use of adjuvant phenol as shown in this and other studies. Minimally invasive methods such as selective embolization and injections of sclerosing agents may result in healing or at least in tolerable persistence of residual lesions but needs repetitive treatments and does not show homogenous results throughout the institutions. Denosumab appears to be an additional option, especially in surgically critical locations such as the spine or the sacrum.

This study aims to describe the angiographic imaging characteristics of superficial venous malformations and evaluate the treatment effectiveness of digital subtraction angiography (DSA)-guided foam sclerotherapy with polidocanol. : This prospective study was conducted in 18 patients with venous malformation treated by DSA-guided sclerotherapy. Treatment outcomes were evaluated based on pain improvement and reduction in lesion size on magnetic resonance imaging (MRI) 6-months posttreatment. A total 21 lesions and 46 sclerotherapy sessions were analyzed. MRI findings presented 8/21 lesions (38.1%) with excellent response, 9/21 (42.9%) with good response, and 3/21 (14.3%) with average response, while one patient (4.8%) showed no response. All patients experienced pain. A significant reduction (p<0.01) was observed in the pre- to posttreatment pain score (5.45 and 0.64, respectively). Over a follow-up period of 1-4 years, three out of four patients (75%) in the retrospective cohort experienced recurrence; one patient had an increased lesion size and pain score, while the other two patients only showed an increased lesion size. No severe complications were seen. DSA-guided sclerotherapy with polidocanol is a safe and effective procedure for reducing lesion size and pain in symptomatic patients with superficial venous malformations.

BACKGROUND
Gastrointestinal (GI) hemangioma has a low incidence among systemic hemangiomas, and some GI hemangiomas occur in the intestine, stomach, and esophagus. Polidocanol has been increasingly used in sclerotherapy. However, this paper reports that minimally invasive treatment of multiple hemangiomas with large diameters can achieve satisfactory results by multipoint injection.
CASE SUMMARY
A 46-year-old female patient was hospitalized in another hospital for cough. We accidentally found thickening of the lower esophagus by chest computed tomography. The patient was eventually diagnosed with multiple GI hemangiomas and underwent a series of examinations including esophagogastroduodenoscopy (EGD), endoscopic ultrasound, and magnetic resonance imaging. We calculated the dose of polidocanol according to the volumes of the hemangiomas, fixed the target vein with the help of a transparent cap, and then administered polidocanol multipoint injection into the hemangiomas under endoscopic guidance. EGD and endoscopic ultrasound showed that the hemangiomas disappeared. The color of the esophageal mucosa returned to normal 1 mo after sclerotherapy.
CONCLUSION
Sclerotherapy may be a safe and effective method for treating multiple hemangiomas of the alimentary canal.
