Purpose: The aim of this study was to evaluate complications in patients with head and neck venous malformations (VMs) treated with foam sclerotherapy using sodium tetradecyl sulfate (STS)., Methods: The authors retrospectively evaluated the complications, pain. and degree of satisfaction in 69 consecutive patients affected by cervicofacial VM managed with STS using the Tessari method in a single institution., Results: The average number of procedures for each patient was 2.1. The most frequent complication was blistering. We observed 1 patient of temporary weakness of a facial nerve branch, 1 paradoxical embolism, and 1 orbital compartment syndrome.The average pain score was 0 (no pain at all) (51.5%). There was no statistically significant correlation between patient satisfaction and the presence of complications or the degree of pain., Conclusions: Sclerotherapy with STS is an effective treatment that yields to very high patient satisfaction. This procedure has an overall low complication rate and is usually effective within a few sessions. However, severe complications may occur; these must be pointed out in the informed consent and the surgeon must be aware of and ready to quickly treat them to prevent long-term sequelae.

Purpose: To study the efficacy and safety of a new sclerosing gel of absolute ethanol in the percutaneous treatment of venous malformations (VM)., Materials and Methods: In this prospective, non-randomized multicenter study patients with clinically and by magnetic resonance imaging diagnosed VM were treated. Efficacy and safety of the gel was evaluated. Therapeutic outcome was judged at day 56 after the last sclerosing therapy. Blood ethanol levels of ethanol were measured after each infusion. Local and systemic adverse events were recorded., Results: Seventy-five (75) patients (age 4-46 y, mean 26 y) were treated in 172 sessions. Compared to no treatment, ethanol gel showed a complete cure rate of about 15% per session (p<0.00001). At the end of the last session, therapeutic outcome was complete (score 2) and partial (score 1) in 28 (37%) and 42 patients (56%), respectively, whereas treatment failure (score 0) was observed in 5 patients (7%). The plasmatic ethanol levels were very low (mean±SEM 0.03±0.06 g L(-1)), with only one patient above the legal 0.5 g L(-1) intoxication limit (0.6 g L(-1)). Forty-six (46) product-related adverse events (all local, none systemic) were reported. They included temporary mild isolated pain (N=21), inflammatory reactions (N=4), and local complications (7 skin necroses, 7 compressive neuropathies, 4 product leakage/fistula, 2 intralesional fibrous or granulomatous tissue, 1 dense node; 12.2% of the infusions). All local complications resolved spontaneously, except for 2 skin necroses requesting surgical paring., Conclusion: Ethanol gel is an embosclerosing substance that provides high efficiency and improves safety of ethanol in the treatment of VM lesions., (Copyright © 2011 Elsevier Ireland Ltd.

Objective: To discuss the differential diagnosis and the management of venous malformations of the vulva., Methods: Five symptomatic patients were treated. The degree of pain and discomfort was self-assessed by using a horizontal visual analog scale before and after treatment. Preoperative evaluation included Doppler ultrasound scanning in all patients and magnetic resonance imaging (MRI) in one. All patients had direct-injection venography and sclerotherapy during the same session. Ethanol was used in two cases and polidocanol in three. Patients were followed-up by means of Doppler ultrasound scanning and office visits., Results: All patients experienced marked swelling after the injection, and one developed cutaneous necrosis that healed within 2 weeks. Transient hemoglobinuria was observed in two cases. No early or late major complications occurred. At a mean follow-up of 23 months (range 5-43), all patients experienced complete relief from symptoms and currently have normal vulvar sensation. Four patients had complete ablation of the treated lesion. In one patient the procedure resulted in a significant, albeit incomplete, occlusion of the lesion, and no further treatment was deemed necessary. From a cosmetic standpoint, both patients and physicians considered the results successful., Conclusion: Vulvar venous malformations should be distinguished from vulvar varicosities, hematomas, soft-tissue neoplasms, and other vascular anomalies. Doppler ultrasound, MRI, and direct-injection venography are the most accurate diagnostic modalities. Sclerotherapy can successfully treat this condition. The procedure should be monitored with an imaging modality, preferably direct-injection venography with digital subtraction serial imaging.

Objectives: To retrospectively evaluate the safety and efficacy of percutaneous sclerotherapy with polidocanol in 9 patients with venous malformations of the glans penis. Vascular malformations of the external genitalia can be aesthetically and functionally disabling. These lesions are rare and their treatment is still controversial., Methods: Seven patients were asymptomatic, seeking advice for cosmetic reasons, and 2 patients had experienced several bleeding episodes during sexual intercourse. In all patients, Doppler ultrasound scanning was performed before treatment. All patients underwent direct intralesional injection of polidocanol. The concentration of the sclerosant varied from 1% to 3%, and the volume of the solution varied from 2 to 4 mL per injection. Four patients required multiple sclerotherapeutic sessions., Results: All patients experienced marked swelling after the injection and three developed cutaneous blistering. Neither cutaneous necrosis nor early or late major complications occurred. At a mean follow-up of 35.1 months, 7 patients were cured and 2 had marked improvement. No patients presented with signs of recurrence, and the outcome was overall cosmetically successful., Conclusions: Sclerotherapy with polidocanol is a well-tolerated, safe, and effective treatment for venous malformations of the penis. In our opinion, it can be considered the treatment of choice.
