Clinical phenotype of adolescent and adult patients with extracranial vascular malformation. J Vasc Surg Venous Lymphat Disord 2023; 11:1034-1044.e3. [PMID: 37030445 DOI: 10.1016/j.jvsv.2023.03.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Revised: 03/08/2023] [Accepted: 03/08/2023] [Indexed: 04/10/2023]
Abstract
OBJECTIVE In recent years, genotypic characterization of congenital vascular malformations (CVMs) has gained attention; however, the spectrum of clinical phenotype remains difficult to attribute to a genetic cause and is rarely described in the adult population. The aim of this study is to describe a consecutive series of adolescent and adult patients in a tertiary center, where a multimodal phenotypic approach was used for diagnosis. METHODS We analyzed clinical findings, imaging, and laboratory results at initial presentation, and set a diagnosis according to the International Society for the Study of Vascular Anomalies (ISSVA) classification for all consecutively registered patients older than 14 years of age who were referred to the Center for Vascular Malformations at the University Hospital of Bern between 2008 and 2021. RESULTS A total of 457 patients were included for analysis (mean age, 35 years; females, 56%). Simple CVMs were the most common (n = 361; 79%), followed by CVMs associated with other anomalies (n = 70; 15%), and combined CVMs (n = 26; 6%). Venous malformations (n = 238) were the most common CVMs overall (52%), and the most common simple CVMs (66%). Pain was the most frequently reported symptom in all patients (simple, combined, and vascular malformation with other anomalies). Pain intensity was more pronounced in simple venous and arteriovenous malformations. Clinical problems were related to the type of CVM diagnosed, with bleeding and skin ulceration in arteriovenous malformations, localized intravascular coagulopathy in venous malformations, and infectious complications in lymphatic malformations. Limb length difference occurred more often in patients with CVMs associated with other anomalies as compared with simple or combined CVM (22.9 vs 2.3%; P < .001). Soft tissue overgrowth was seen in one-quarter of all patients independent of the ISSVA group. CONCLUSIONS In our adult and adolescent population with peripheral vascular malformations, simple venous malformations predominated, with pain as the most common clinical symptom. In one-quarter of cases, patients with vascular malformations presented with associated anomalies on tissue growth. The differentiation of clinical presentation with or without accompanying growth abnormalities need to be added to the ISSVA classification. Phenotypic characterization considering vascular and non-vascular features remains the cornerstone of diagnosis in adult as well as pediatric patients.

Abstract
OBJECTIVE Sclerotherapy for venous malformation has been widely used; however, no guidelines are available to assess the effectiveness of different sclerotherapy agents. We conducted a systematic review and network meta-analysis to investigate the effectiveness of sclerotherapy agents for venous malformations. METHODS Three electronic databases were searched from their inception (1950) to April 29, 2021. Studies comparing the effectiveness of different sclerotherapy agents were included. The risk of bias within and across studies was assessed. Pairwise meta-analyses were conducted, followed by a network meta-analysis. We also assessed inconsistency and publishing bias using various approaches. RESULTS Seven studies with 547 patients in six arms were included in the present study. We defined the response and complete response as two separate outcomes. Significant differences were observed in four comparisons with respect to the response (ethanol vs bleomycin, ethanol vs polidocanol, ethanol vs sodium tetradecyl sulfate, polidocanol vs sodium tetradecyl sulfate). No statistically significant differences were found in the other comparisons. The evidence network revealed that for the response outcome, ethanol ranked first, followed by pingyangmycin, polidocanol, sodium morrhuate, bleomycin, and, finally, sodium tetradecyl sulfate. For the complete response outcome, pingyangmycin had the best results, followed by sodium morrhuate, polidocanol, ethanol, bleomycin, and, finally, sodium tetradecyl sulfate. Major complications, such as facial nerve palsy, serious local swelling, and necrosis, had occurred mostly in the ethanol group and rarely in the other groups. Because of the limited data, no further analysis of major complications was conducted. Our confidence in the comparisons and rankings was low. We found no verified inconsistency or publishing bias in the present study using the existing approaches. CONCLUSIONS Ethanol showed a significantly better response statistically compared with the other agents. However, ethanol had also resulted in the highest incidence of complications. Pingyangmycin showed the second-best response, best complete response, and a low rate of complications, respectively. Overall, pingyangmycin achieved excellent performance and balance in terms of the different outcomes. However, they could not be adequately recommended from the available data. More superior trials, especially randomized controlled trials, are needed in the future.

Abstract
Arterioenteric or arteriotracheal fistula is a known complication of an aberrant right subclavian artery (ARSA) and is often associated with prolonged nasogastric or endotracheal intubation or oesophageal stenting. Fistula formation from the ARSA can present unexpectedly with rapid exsanguination with massive haemoptysis or haematemesis, and unless promptly recognised and treated is rapidly fatal. We present a novel endovascular method for treating a fistula between the oesophagus, trachea and an ARSA in an unstable patient following oesophageal stent removal, utilising a covered iliac limb stent, eliminating the need for an open surgical approach.

Abstract
BACKGROUND Cerebral arterio venous malformations (AVM) are a major causal factor for intracranial hemorrhage, which result in permanent disability or death. The molecular mechanisms of AVM are complex, and their pathogenesis remains an enigma. Current research on cerebral AVM is focused on characterizing the molecular features of AVM nidus to elucidate the aberrant signaling pathways. The initial stimuli that lead to the development of AVM nidus structures between a dilated artery and a vein are however not known. METHODS In order to understand the molecular basis of development of cerebral AVM, we used in-depth RNA sequencing with the total RNA isolated from cerebral AVM nidus. Immunoblot and qRT-PCR assays were used to study the differential gene expression in AVM nidus, and immunofluorescence staining was used to study the expression pattern of aberrant proteins in AVM nidus and control tissues. Immunohistochemistry was used to study the expression pattern of aberrant proteins in AVM nidus and control tissues. RESULTS The transcriptome study has identified 38 differentially expressed genes in cerebral AVM nidus, of which 35 genes were upregulated and 3 genes were downregulated. A final modular analysis identified an upregulation of ALDH1A2, a key rate-limiting enzyme of retinoic acid signaling pathway. Further analysis revealed that CYR61, a regulator of angiogenesis, and the target gene for retinoic acid signaling is upregulated in AVM nidus. We observed that astrocytes associated with AVM nidus are abnormal with increased expression of GFAP and Vimentin. Triple immunofluorescence staining of the AVM nidus revealed that CYR61 was also overexpressed in the abnormal astrocytes associated with AVM tissue. CONCLUSION Using high-throughput RNA sequencing analysis and immunostaining, we report deregulated expression of retinoic acid signaling genes in AVM nidus and its associated astrocytes and speculate that this might trigger the abnormal angiogenesis and the development of cerebral AVM in humans.

Abstract
OBJECTIVE Cerebral arteriovenous malformation (AVM) is characterised by an abnormal tangle of arteries and veins, the rupture of which is a significant portion of the morbidity and mortality cases, especially in young populations. However, the exact risk factors and pathophysiologic mechanisms of AVM remain poorly understood. RNF213 variants have been identified as obvious susceptible factors of several cerebrovascular disorders, such as Moyamoya disease and intracranial aneurysms. Thus, this study aimed to determine whether there is an association between RNF213 rare variants and AVM. METHODS The AVM group included 22 patients with AVM. The control group included 1007 samples from the GeneSky in-house database and 208 samples from the 1000 Genome Project of Chinese Han Population. Genomic DNA samples were extracted from the peripheral blood of the AVM patients, and targeted exome sequencing of RNF213 was performed to assess the existence of low-frequency or rare variants. Sanger sequencing was performed to validate the identified variants. Logistic regression analysis was performed to calculate the odds ratios (ORs) and 95 % confidence intervals (CIs) of the candidate variants and risk of AVM. Statistical analyses were performed using SPSS version 21.0. RESULTS The RNF213 c.10997T>C variant (amino acid mutation p.M3666T, NM_001256071) was observed in two AVM patients after filtration. It was significantly associated with AVM in the Chinese population (ORs, 10.30 and 25.08; 95 %; CIs, 1.38-77.10 and 4.34-144.90 compared with 1000 Genome Project of Chinese Han Population and GeneSky in-house database, respectively). CONCLUSION Rare variants of RNF213 are associated with AVM in the Chinese population, suggesting the important role of RNF213 in AVM. Further studies are needed to verify these findings.

Abstract
BACKGROUND Vascular malformations (VMs) involving the hand and forearm in children provide management challenges due to complex anatomy, indispensable functionality and developmental implications. METHODS The institution's Vascular Registry was searched for patients with hand and arm VMs, supplemented by chart review of included patients. RESULTS Twenty-one patients were identified, 52% male, with mean presenting age 5.2 years. Venous malformations predominated (71%), followed by lymphatic-venous (19%), lymphatic (5%) and glomuvenous (5%). Symptoms included pain (76%), swelling (71%), cosmetic concerns (81%), functional compromise (29%) and stiffness (5%). Imaging modality was ultrasound (100%), and magnetic resonance imaging (71%). Treatment included compression (62%), sclerotherapy (62%) and surgery (24%). Post-sclerotherapy ultrasounds showed complete sclerosis (25%), near complete sclerosis (58%) and partial sclerosis (17%). Post-surgery, patients reported improved cosmesis (80%), size (100%), pain (60%) and function (40%). Complications occurred in 24%, including bleeding, digital ischaemia and thrombosis. Mean follow-up was 3.4 years. CONCLUSION Children with low-flow VMs of the hand and forearm experience significant symptoms and functional limitations. A multidisciplinary approach to management ensures optimal outcomes.

Abstract
OBJECTIVE Congenital vascular malformations are a heterogeneous group of lesions with the potential to cause significant lifelong morbidity in children. Diagnosis and treatment of these lesions may be complex and require a multidisciplinary approach. Sclerotherapy is widely used for the treatment of low-flow vascular malformations (LFVMs) as an alternative to surgical resection in adults; however, limited data of its use in a pediatric setting are available. The purpose of this study was to evaluate the efficacy and safety of sclerotherapy for pediatric LFVMs. METHODS In this retrospective study, we reviewed our multidisciplinary vascular malformations team database for all patients younger than 18 years treated for congenital vascular malformations from 2008 to 2017. Of these, patients with LFVM treated with foam sclerotherapy were included. Dynamic contrast-enhanced magnetic resonance imaging was used to select patients for sclerotherapy by the multidisciplinary team. Foam sclerotherapy was performed with either polidocanol or sodium tetradecyl sulfate. Patients' characteristics, including demographics, presenting symptoms, and anatomic location of malformation, were assessed. Outcomes included treatment response, number of procedures, and postprocedural complications. RESULTS The 61 patients with 61 LFVMs included 27 boys (44.3%) and 34 girls (55.7%), with mean age of 10.3 years (standard deviation, ± 5.3 years). The cohort included 32 venous (52.5%), 16 lymphatic (26.2%), and 8 mixed venous and lymphatic (13.1%) malformations along with 5 (8.2%) associated with Klippel-Trénaunay syndrome. Primary indications for intervention included pain and swelling (n = 12 [19.6%]), pain alone (n = 23 [37.7%]), swelling alone (n = 15 [24.6%]), functional impairment (n = 8 [13.1%]), and bleeding (n = 3 [4.9%]). Anatomic distributions varied, with 13 head and neck (21.3%), 5 truncal (8.2%), 10 upper extremity (16.4%), 27 lower extremity (44.3%), and 6 diffuse (9.8%). Among the head and neck lesions, 8 (13.1%) extended to the face; and of the extremity lesions, 5 (8.2%) extended to the hand and 17 (27.9%) to the foot. Overall, sclerotherapy resulted in significant improvement or complete resolution of symptoms in 53 patients (86.9%). Complications were observed in seven patients (11.4%); six cases (9.8%) of superficial skin ulceration resolved without intervention, and one infection (1.6%) required antibiotics. No patients experienced adverse hemodynamic consequences or venous thromboembolism. CONCLUSIONS This series of pediatric LFVMs, the largest of its kind to date, demonstrates that sclerotherapy with foam-based agents effectively reduces symptoms with an acceptable rate of complications. Further study is needed to determine the optimal sclerosing agents for individual subsets of LFVMs in the pediatric population.

Abstract
Vascular malformations are abnormal connections between blood vessels that can have various endothelial characteristics. Although uncommon, these malformations can present challenging diagnostic and therapeutic scenarios. The use of interventional radiology techniques in the management of various vascular malformations is an attractive option because of the ability to treat these malformations at the most appropriate anatomic location and in the most effective manner. Techniques such as coil embolization of intrahepatic portosystemic shunts and liquid embolization of arteriovenous fistulae/malformations have shown tremendous potential as treatments for these challenging diseases.

Abstract
PURPOSE High-flow arteriovenous malformations (AVMs) may pose a challenge for endovascular treatment due to high-flow rates. Incomplete treatment, recurrence, or even worsening can occur if a proper management is not performed. We report a case successfully treated with endovascular therapy. CASE REPORT A 37-year-old male was referred to our hospital with a soft tumor in the left thigh, limb asymmetry and associated pain. Doppler ultrasound and magnetic resonance imaging showed an extensive high-flow AVM with a venous aneurysm of 40 mm diameter. Diagnostic angiography identified multiple feeding vessels from the profunda femoris and superficial femoral arteries. Two endovascular interventions were performed within 1 month, combining afferent vessel embolization and percutaneous thrombin injection into the nidus, to exclude the AVM. Two-year imaging follow-up revealed thrombosis of the malformation. The patient remained asymptomatic with normal thigh diameter. No complications were documented in any of the sessions. CONCLUSION Endovascular therapy could be a safe and effective option for AVM as long as it includes not only feeding vessels embolization but also complete occlusion of the nidus.

Abstract
Vascular malformations are developmental congenital abnormalities of the vascular system which may involve any segment of the vascular tree such as capillaries, veins, arteries, or lymphatics. Arteriovenous malformations (AVMs) are congenital vascular lesions, initially described as “erectile tumors,” characterized by atypical aggregation of dilated arteries and veins. They may occur in any part of the body, including the brain, heart, liver, and skin. Severe clinical manifestations occur only in the brain. There is absence of normal vascular structure at the subarteriolar level and dearth of capillary bed resulting in aberrant arteriovenous shunting. The causative factor and pathogenic mechanisms of AVMs are unknown. Importantly, no marker proteins have been identified for AVM. AVM is a high flow vascular malformation and is considered to develop because of variability in the hemodynamic forces of blood flow. Altered local hemodynamics in the blood vessels can affect cellular metabolism and may trigger epigenetic factors of the endothelial cell. The genes that are recognized to be associated with AVM might be modulated by various epigenetic factors. We propose that AVMs result from a series of changes in the DNA methylation and histone modifications in the genes connected to vascular development. Aberrant epigenetic modifications in the genome of endothelial cells may drive the artery or vein to an aberrant phenotype. This review focuses on the molecular pathways of arterial and venous development and discusses the role of hemodynamic forces in the development of AVM and possible link between hemodynamic forces and epigenetic mechanisms in the pathogenesis of AVM.

Abstract
BACKGROUND Vascular malformations are congenital anomalies of the vascular system. Intralesional bleomycin injections are commonly used to treat vascular malformations. However, pulmonary fibrosis could potentially be a severe complication, known from systemic bleomycin therapy for malignancies. In this study, the authors investigate the effectiveness and safety of bleomycin (A2, B2, and A5) injections for vascular malformations, when possible relative to other sclerosants. METHODS The authors performed a PubMed, Embase, Cochrane Central Register of Controlled Trials, and gray literature search for studies (1995 to the present) reporting outcome of intralesional bleomycin injections in patients with vascular malformations (n ≥ 10). Predefined outcome measures of interest were size reduction, symptom relief, quality of life, adverse events (including pulmonary fibrosis), and patient satisfaction. RESULTS Twenty-seven studies enrolling 1325 patients were included. Quality of evidence was generally low. Good to excellent size reduction was reported in 84 percent of lymphatic and 87 percent of venous malformations. Pulmonary fibrosis was never encountered. Meta-analysis of four studies on venous malformations treated with bleomycin versus other sclerosants showed similar size reduction (OR, 0.67; 95 percent CI, 0.24 to 1.88) but a significantly lower adverse event rate (OR, 0.1; 95 percent CI, 0.03 to 0.39) and fewer severe complications after bleomycin. Symptom relief, quality of life, and patient satisfaction were reported inadequately. CONCLUSIONS The authors' data suggest that bleomycin is effective in reducing the size of lymphatic and venous malformations, and leads to a lower adverse event rate and fewer severe complications than other sclerosants. The included literature does not provide evidence that pulmonary fibrosis is a complication of intralesional bleomycin injections. This study represents the "best available" evidence; however, only low- to moderate-quality studies were available. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
Objective An acquired uterine arteriovenous malformation (AVM) is a rare cause of vaginal bleeding and, although hysterectomy is the definitive therapy, transcatheter embolization (TCE) provides an alternative treatment option. This systematic review presents the indications, technique, and outcomes for transcatheter treatment of the acquired uterine AVMs. Study Design Literature databases were searched from 2003 to 2013 for eligible clinical studies, including the patient characteristics, procedural indication, results, complications, as well as descriptions on laterality and embolic agents utilized. Results A total of 40 studies were included comprising of 54 patients (average age of 33.4 years). TCE had a primary success rate with symptomatic control of 61% (31 patients) and secondary success rate of 91% after repeated embolization. When combined with medical therapy, symptom resolution was noted in 48 (85%) patients without more invasive surgical procedures. Conclusion Low-level evidence supports the role of TCE, including in the event of persistent bleeding following initial embolization, for the treatment of acquired uterine AVMs. The variety of embolic agents and laterality of approach delineate the importance of refining procedural protocols in the treatment of the acquired uterine AVM. Condensation A review on the management of patients with acquired uterine AVMs.

Abstract
PURPOSE The purpose of this study was to determine the feasibility, safety, and early effectiveness of percutaneous image-guided ablation as second-line treatment for symptomatic soft-tissue vascular anomalies (VA). MATERIALS AND METHODS An IRB-approved retrospective review was undertaken of all patients who underwent percutaneous image-guided ablation as second-line therapy for treatment of symptomatic soft-tissue VA during the period from 1/1/2008 to 5/20/2014. US/CT- or MRI-guided and monitored cryoablation or MRI-guided and monitored laser ablation was performed. Clinical follow-up began at one-month post-ablation. RESULTS Eight patients with nine torso or lower extremity VA were treated with US/CT (N = 4) or MRI-guided (N = 2) cryoablation or MRI-guided laser ablation (N = 5) for moderate to severe pain (N = 7) or diffuse bleeding secondary to hemangioma-thrombocytopenia syndrome (N = 1). The median maximal diameter was 9.0 cm (6.5-11.1 cm) and 2.5 cm (2.3-5.3 cm) for VA undergoing cryoablation and laser ablation, respectively. Seven VA were ablated in one session, one VA initially treated with MRI-guided cryoablation for severe pain was re-treated with MRI-guided laser ablation due to persistent moderate pain, and one VA was treated in a planned two-stage session due to large VA size. At an average follow-up of 19.8 months (range 2-62 months), 7 of 7 patients with painful VA reported symptomatic pain relief. There was no recurrence of bleeding at five-year post-ablation in the patient with hemangioma-thrombocytopenia syndrome. There were two minor complications and no major complications. CONCLUSION Image-guided percutaneous ablation is a feasible, safe, and effective second-line treatment option for symptomatic VA.

Abstract
CASE DESCRIPTION An 11-year-old castrated male Tibetan Mastiff was evaluated because of a visibly enlarged blood vessel and progressively worsening swelling of the right hind limb. CLINICAL FINDINGS On physical examination, the right hind limb was markedly larger than the left hind limb and the dog was minimally weight bearing on the affected limb. A bruit was auscultated over the affected region. Ultrasonography of the tarsal region of the right hind limb revealed an artery with turbulent flow that communicated with venous drainage. A CT scan confirmed the presence of an arteriovenous malformation (AVM). TREATMENT AND OUTCOME Embolization of the AVM with a liquid embolic agent (ethylene-vinyl alcohol copolymer dissolved in dimethyl sulfoxide) was elected. An arteriogram was performed prior to treatment and delineated the vessels that were targeted for embolization. The embolic agent was infused into the AVM, and a postinjection arteriogram confirmed complete occlusion of the AVM nidus and normal arterial flow to the paw with subsequent normal venous drainage. The circumference of the abnormal paw was 51 cm before the procedure and 22.9 cm at 4 weeks after the procedure. Additionally, the gait of the dog dramatically improved. No complications associated with the procedure developed. CLINICAL RELEVANCE Peripheral AVMs in dogs are uncommon, and described treatment options are limited and generally associated with serious morbidity. A liquid embolic agent, ethylene-vinyl alcohol copolymer dissolved in dimethyl sulfoxide, was successfully administered in this case, and no morbidity was observed secondary to the procedure. Clinical success was characterized by substantial improvement in limb swelling and marked improvement in the gait of the dog.

Abstract
PURPOSE To estimate the risk of nerve injuries and assess outcomes after sodium tetradecyl sulfate (STS) sclerotherapy of venous malformations (VMs) in children. MATERIALS AND METHODS Sclerotherapy is the treatment of choice for most VMs, but all sclerotherapy agents are associated with the risk of complications. Neuropathy is considered a rare but potentially serious complication of venous sclerotherapy. The institutional review board waived ethical approval for this retrospective review, in which 647 sclerotherapy procedures were performed in 204 patients (104 female and 100 male patients; mean age, 9 years 6 months [range, 6 months to 17 years 11 months]) as treatment for symptomatic VMs. Technical and clinical success of the treatment was evaluated. Complications were reviewed with a particular focus on nerve injury. Informed consent, specifying the risk of neuropathy, as well as pain, swelling, infection, risks of anesthesia, skin injury, nonresolution or worsening of symptoms, and possible need for further or multiple procedures, was obtained for all patients. Standard sclerotherapy techniques were used. Technical details of all procedures were recorded prospectively. Follow-up included immediate postprocedural assessment and outpatient clinic review. All nerve injuries were recorded. Patients were monitored and treated according to clinical need. Confidence intervals were calculated by using the Wilson method, without correction for continuity. RESULTS Treatment was technically successful in 197 of 204 patients (96.6%), and clinical success was achieved in 174 of 204 (85.3%). Thirty-seven of the 647 procedures (5.7%) resulted in a complication, including 11 cases of excessive swelling, nine cases of skin injury, two patients with infection, and two with pain. Motor and/or sensory nerve injuries occurred after seven procedures (1.1%). Five of the seven children had undergone at least one previous sclerotherapy procedure. Neuropathy resolved spontaneously in four patients and partially recovered in three, of whom two underwent surgery. Surgery included debridement of necrotic tissue, carpal tunnel decompression, and external neurolysis. CONCLUSION Nerve injury is an unusual but not rare complication of STS sclerotherapy. A degree of recovery, which may be complete, can be expected in most patients.

Abstract
OBJECTIVE Few cases of muscle arteriovenous malformations have been reported in literature to date. CASE REPORT We report the case of a 32-year-old man presenting a muscle arteriovenous malformation involving the vastus lateralis muscle with recurrent episodes of pain. The patient was treated by transcatheter embolization with Glubran 2 acrylic glue. There were no periprocedural or subsequent clinical complications, the glue resulted in successful selective occlusion and the patient showed resolution of symptoms at the six-months follow-up. CONCLUSIONS Endovascular therapy has been shown to be beneficial in patients with high surgical risks and is the treatment of choice for arteriovenous malformation lesions that extend beyond the deep fascia and involve muscle, tendon, and bone. Glubran 2 constitutes a useful tool to attempt embolization of the muscle arteriovenous malformation nidus, with easier handling and promising results.

Abstract
OBJECTIVE To assess quality of life (QoL) in patients with congenital vascular malformations (CVMs) and to identify factors of CVMs associated with poor QoL, including high psychological and/or somatic (physical) distress. METHODS We evaluated 71 patients (mean age, 40 ± 16 years; 51% women) with arteriovenous (n = 10), venous/capillary (n = 34), lymphatic (n = 10), and combined (n = 17) malformations. All patients completed validated psychometric assessment tools, which were the 36-Item Short Form Health Survey, the Hospital Anxiety and Depression Scale, the Patient Health Questionnaire-15, and the Pain Disability Index. RESULTS Compared with population norms, the group of CVM patients as a whole showed lower 36-Item Short Form Health Survey Physical (46 vs 50) and Mental (46 vs 52) Component Summary scores, indicating impaired physical and mental health. In addition, 13% of patients with CVMs had clinically relevant psychological distress (Hospital Anxiety and Depression Scale total scores ≥17), and 15% had increased somatic distress (Patient Health Questionnaire-15 total scores ≥10). Greater levels of psychological and somatic distress were significantly associated with lower scores of virtually all of the eight 36-Item Short Form Health Survey subscales (P < .05). CONCLUSIONS Our findings suggest that, compared with a normal population, CVM patients have a lower QoL that is accompanied by increased psychological and somatic distress. In treating patients with CVMs, it is important to be aware of the psychological impact of this rare illness and to offer appropriate support.

Abstract
BACKGROUND Arteriovenous malformations (AVM) of the head and neck are rare conditions with the majority of primary sites in the mid-face. Progression can lead to massive life-threatening bleeding. Treatment of choice is the combination of embolization and surgical resection. Diagnosis and management of AVM has been facilitated in recent years by the progress in imaging techniques and various microsurgical and endovascular embolization procedures. METHODS This report presents the interdisciplinary approach to a case of life-threatening AVM of the mid-face in a 30-year-old patient. RESULTS Angiography with embolization followed by resection and plastic reconstruction was performed. Follow-up showed incomplete obliteration of the AVM and lead to additional embolizations via the anastomosed radial artery. Complete eradication of the AVM was not possible during the three year follow-up period. CONCLUSION In extensive vascular malformations of the head and neck, complete surgical removal is often impossible and associated with high risk of complications and mortality. Endovascular embolization is limited by the location of the AVM and can potentially cause stroke, ischaemia, necrosis, bleeding, blindness and adverse haemodynamic changes.

Abstract
BACKGROUND Absolute ethanol sclerotherapy provides a reliable treatment for facial venous malformation, although facial nerve injury may occur after sclerotherapy. This study is a retrospective review of facial nerve dysfunction after sclerotherapy. METHODS A total of 91 patients with facial venous malformations accepted 288 ethanol sclerotherapy sessions. The facial nerve dysfunctions caused by the therapy were evaluated and analyzed. RESULTS There were 9 instances of facial nerve injury. For 18 sessions of sclerotherapy in the temporal region, 5.6% of patients experienced injury to the temporal branch; for 12 sessions in the zygomatic region, 41.7% of patients experienced injury to the zygomatic branch. After patients were treated with medication, 8 of 9 instances of nerve injury recovered. CONCLUSIONS The zygomatic and temporal branches of the facial nerve were the most vulnerable to injury after ethanol sclerotherapy. Surgeons are thus called on to pay more attention when performing ethanol sclerotherapy in those areas.

[DOI: 10.1016/j.otohns.2010.08.053] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2010] [Revised: 08/25/2010] [Accepted: 08/31/2010] [Indexed: 11/29/2022]
Abstract
OBJECTIVE: To describe a typical presentation of venous malformation within the masseter muscle, including physical findings and imaging, and to present the University of California, San Francisco's (UCSF) Vascular Anomalies and Birthmark Center's (VABC) experience with sclerotherapy for these lesions. STUDY DESIGN: Case series with chart review. SETTING: Tertiary care medical center. SUBJECTS AND METHODS: Retrospective chart review of all patients presenting to the UCSF VABC over a 10-year period. RESULTS: Twelve patients with isolated venous malformations of the masseter muscle were identified. All of these patients presented with pain and facial asymmetry that was more pronounced with jaw-clenching. All underwent magnetic resonance imaging demonstrating a T2 hyperintense homogenous mass contained within the masseter muscle. Eleven of 12 had evidence on imaging of phleboliths within the mass; 10 patients underwent sclerotherapy. All treated patients had initial improvement in symptoms and/or appearance. Seven of 10 have had sustained improvement at a mean follow-up of 28 months. CONCLUSION: Masseteric venous malformations have a typical clinical presentation and imaging characteristics that should allow clinicians to distinguish them from other abnormalities presenting in this area. Percutaneous sclerotherapy should be considered as a treatment option for these patients and can result in excellent outcomes.

Abstract
As malformações vasculares periféricas compreendem um espectro de lesões que se tornam aparentes no decorrer da vida e podem ser encontradas em praticamente todo o corpo. São pouco comuns e frequentemente confundidas com o hemangioma infantil. Estas doenças são completamente distintas tanto em relação à história clínica como ao prognóstico e às formas de tratamento. Nestas lesões, a história evolutiva e as características do exame físico são de extrema importância para o adequado diagnóstico clinicorradiológico, que guiará a melhor alternativa terapêutica. As classificações mais recentes dividem as malformações vasculares periféricas levando em consideração o fluxo sanguíneo (alto e baixo) e os componentes vasculares envolvidos (arteriais, capilares, linfáticos e venosos). As malformações vasculares periféricas representam um desafio diagnóstico e terapêutico, e exames complementares como tomografia computadorizada, ultrassonografia com Doppler e ressonância magnética, em conjunto com a história clínica, podem trazer informações quanto às características de fluxo e à extensão das lesões. Arteriografia e flebografia confirmam o diagnóstico, avaliam a sua extensão e orientam a decisão terapêutica. Malformações de baixo fluxo geralmente são tratadas por abordagem percutânea e injeção de agente esclerosante, enquanto para as malformações de alto fluxo o acesso é endovascular com uso de agentes embolizantes permanentes líquidos ou sólidos.
