Hybrid treatment of fibroadipose vascular anomaly: A case report.

BACKGROUND: First identified in 2014, fibroadipose vascular anomaly (FAVA) is a very rare type of venous and lymphatic malformation. Marked by tough fibrofatty tissue in the extremities overtaking portions of the muscles, it is associated with constant pain and contracture of the affected extremity. There is a paucity of literature, and no guidelines on treatment procedure are available. This case highlights the role of hybrid treatment with primary ethanol percutaneous ethanol embolization and additional surgery for radicality in excision of FAVA lesions. CASE SUMMARY: A 9-year-old girl with FAVA underwent the hybrid treatment. The achievements of complete excision, clinical response, and patient satisfaction in long-term follow-up were assessed. Following the hybrid treatment, the patient experienced significant improvement in pain. Concurrent symptoms of physical limitation, leg swelling, and skin hyperesthesia also improved. The clinical benefit, supported by postoperative physiotherapy, was well stabilized at 6-month follow-up, resulting in complete patient satisfaction at 12- and 36-month follow-ups. No major complications were encountered. CONCLUSION: Ethanol embolization plus surgery is a safe, effective, and long-term hybrid treatment of symptomatic FAVA lesions.

SECg Staging System: A New Approach to the Management of Arteriovenous Malformations of the Head and Neck.

OBJECTIVES: Arteriovenous malformations (AVM) are the most troublesome vascular malformations to deal with. They tend to behave like low-grade malignancies with infiltrative and disruptive growth. Crucially, the clinical course of an AVM that has been improperly managed is usually characterized by a recurrence that is much more aggressive than the original disease. As in oncology, a comprehensive staging system is highly desirable and is to date lacking in the literature. The authors present a new comprehensive staging system. METHODS: A multicentric multidisciplinary team of experts in the field of vascular anomalies has created this new staging system. The SECg staging system defines the local extension of the disease (S1-S4), the vascular architecture of the malformation (E1, E2, E3), the severity of the symptoms (C0-C3) and the presence or absence of growth of the AVM (g+, g-). RESULTS: This staging system allows to address all the aspects of AVMs and, more importantly, to help building an appropriate, individualized treatment plan for affected patients. After being staged an AVM can be defined as (a) healable, (b) healable with predicted sequelae, or (c) unhealable. Then, the SECg system allows to outline (a) absolute indications, (b) relative indications, and (c) no indications for treatment. The purpose of the treatment (radical, palliative) is furthermore taken into consideration. CONCLUSIONS: This multicentric, the SECg staging system that this multidisciplinary group of Authors has defined allows for a comprehensive staging of the disease which in turn has enabled to outline an algorithm to properly manage AVMs.

Complications After Treatment of Head and Neck Venous Malformations With Sodium Tetradecyl Sulfate Foam.

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.

[Linee guida flebo-linfologiche SIF-SICVE 2016 della Società Italiana di Flebologia e della Società Italiana di Chirurgia Vascolare ed Endovascolare].

Phlebology is not a specialty for its own in Italy. Phlebological patients are treated by vascular and general surgeons, dermatologists, phlebologists, angiologists, internists and even general practitioners. Even tough guidelines present a series of recommendations based on evidence-based medicine, guidelines may also be a tool to unify the diagnostic and therapeutic approach in a vast medical field like phlebology. Since vascular surgeons and phlebologists are particularly involved in phlebology-related pathologies the scientific societies of the Italian Society of Phlebology (SIF) and the Italian Society for Vascular and Endovascular Surgery (SICVE) decided to cooperate for the preparation of phlebo-lymphological guidelines. These guidelines comprehend also an important chapter dealing with the lymphology of the lower extremities; phlebological active physicians are often faced with lymphatic pathologies and a good differential diagnosis can be sometimes very helpful. Sclerotherapy and Surgery as the major therapeutical alternatives are extensively analyzed, but also the compression therapy, the medical and physical therapy are presented under the critical view of evidence based analyses. Separate chapters deal with the treatment alternatives for superficial and deep venous thromboses and the recommendations for the treatment of venous ulcers. The current scientific evidences were confronted with the experiences of Italian specialists and the particular practice and reality in Italy. They represent therefore the actual valid positions and recommendations in Italy which shall be updated regularly.

Treatment of venous malformations: first experience with a new sclerosing agent--a multicenter study.

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.

Perioperative stress response to carotid endarterectomy: the impact of anesthetic modality.

OBJECTIVE: Surgery for extracranial carotid artery disease has been challenged by carotid angioplasty stenting because the latter is less invasive and avoids surgical trauma. In fact, the magnitude of the perioperative stress response evoked by carotid endarterectomy (CEA) has never been evaluated. Our aim was to determine the degree of surgical trauma caused by CEA and to define differences related to the use of locoregional or general anesthesia. METHODS: We prospectively studied 113 consecutive CEAs performed on 109 patients admitted at a community institutional center. Patients were stratified for demographics and risk factors and operated on under locoregional (LA) or general anesthesia (GA) depending on both the surgeon preference and patient's compliance. Selective carotid shunting was performed for patients who manifested neurologic deficits under LA or had stump pressure values 120 minutes. Three patients experienced an intraoperative neurologic event and had higher post-CACC cortisol values as compared to asymptomatic patients. CONCLUSIONS: Intraoperative surgical stress was higher under LA and was blunted by carotid shunting under both LA and GA. Within 2 hours after surgery the anesthetic modality no longer had any impact on surgical trauma. The stress response to CEA, regardless of the type of anesthesia, was abolished within 24 hours. Intraoperative stress response, namely hypercortisolemia, directly correlated with subclinical and clinical cerebral hypoperfusion/ischemia during CACC. Hence, attenuation of the stress response to CEA might decrease the incidence of cerebral ischemic events.

Reversible cardiac arrest after polidocanol sclerotherapy of peripheral venous malformation.

BACKGROUND: Polidocanol sclerotherapy is a well-established therapeutic modality for the treatment of venous malformations. Systemic complications are extremely rare. OBJECTIVE: To report a case of cardiac complication after polidocanol injection of peripheral venous malformation. METHODS: A case report and a review of the English language literature using a published MEDLINE search strategy. RESULTS: A patient undergoing polidocanol sclerotherapy for a symptomatic venous malformation of the right inferior limb developed cardiac arrest shortly after injection of the sclerosing agent which was promptly reversed. CONCLUSION: Systemic complications following sclerotherapy may occur even when the sclerosant is injected in peripheral veins or venous malformations. Clinicians should be alerted to the possibility of uncommon but life-threatening adverse effects.
