ABSTRACT
Las anomalías vasculares de la órbita (AVO) son un grupo heterogéneo de patologías que pueden presentarse con frecuencia en el cono orbitario, la región periorbitaria o dentro de la órbita misma. Las AVO se dividen en tumores y malformaciones. Su presentación clínica más frecuente es el exoftalmos, asociado o no a alteración del eje visual. Además, pueden presentar complicaciones agudas, como hemorragia intralesional o celulitis entre las más frecuentes, y complicaciones crónicas, como ambliopía y afectación de la agudeza visual a largo plazo. La evolución de las técnicas de imágenes, el uso de nuevos fármacos y la utilización de innovadores procedimientos en radiología intervencionista han posibilitado obtener una mejora significativa en los procesos diagnósticos y terapéuticos de estos pacientes, permitiendo un diagnóstico y tratamiento preciso.
Orbital vascular anomalies (OVAs) are a heterogeneous group of disorders frequently found in the orbital cone, the periorbital region, or within the orbit itself. OVAs are divided into tumors and malformations. The most frequent clinical presentation is exophthalmos, associated or not with an alteration of the visual axis. They may also cause acute complications, being intralesional bleeding or cellulitis the most frequent, and chronic complications, such as amblyopia and long-term visual acuity impairment. The development of imaging techniques, the use of new drugs, and the implementation of innovative procedures in interventional radiology have resulted in a significant improvement in the diagnostic and therapeutic approaches to these patients, essential to an accurate diagnosis and management.

Objective: To analyze and compare the efficacy and safety of pingyangmycin fibrin glue composite (PFG) and pingyangmycin dexamethasone composite (PD) in the treatment of pharyngolaryngeal venous malformation (VM). Methods: The clinical data of 98 patients with pharyngolaryngeal VM who underwent sclerotherapy with pingyangmycin composite in the First Affiliated Hospital of Sun Yat-sen University from June 2013 to November 2022 were retrospectively analyzed. According to their treatment, patients were divided into PFG group (n=34) and PD group (n=64), among those patients there were 54 males and 44 females, aged 1-77(37.06±18.86)years. The lesion size, total treatment times and adverse events were recorded before and after treatment. And the efficacy was divided into three grades: recovery, effective and invalid. According to the length of VM, all patients were divided into three subgroups, to compare the differences in efficacy and treatment times between each two groups.And finally the adverse events and their treatments were analyzed. SPSS 25.0 software was used for statistical analysis. Results: The efficacy of PFG group was 94.11%(32/34), the recovery rate was 85.29%(29/34).And the efficacy of PD group was 93.75%(60/64), the recovery rate was 64.06%(41/64). No serious adverse eventst occurred in subgroup comparison, there was no statistical difference between the two groups in efficacy and the times of treatments when the length was≤3 cm (Zefficacy=1.04, ttreatment times=2.18, P>0.05); when the length was 3-5 cm, there was no significant efficacy difference between the two groups(Zefficacy=1.17, P>0.05), but the treatment times of PFG were less (ttreatment times=4.87, P<0.01); when the length≥5 cm, efficacy of PFG was significantly better than PD (Zefficacy=2.94, P<0.01), and had fewer treatments times (ttreatment times=2.16, P<0.01). There were no serious adverse events in either group during treatment and follow-up. Conclusion: Both PFG and PD are safe and effective composite sclerotherapy agent for the treatment of laryngeal VM, but PFG has a higher cure rate and fewer treatment times for massive lesions.

Vascular malformations are due to abnormal development of blood and/or lymphatic vessels during embryonic life without endothelial cell proliferation. Most of the previous treatments were symptomatic methods as surgery and sclerotherapy because the pathogenic mechanism was not clearly understood. With advances in molecular biology, the pathogenesis of vascular malformations is thought to be related to inherited and/or somatic mutations that eventually activate the PI3K/ATK/mTOR, Ras/Raf/MEK/ERK pathways. Also, related studies have promoted the use of targeted inhibitors. This article provides a review of current causative genes and targeted drugs for pediatric vascular malformations, aiming to provide a basis for promoting accurate molecular diagnosis and precision targeted therapy for these diseases.

Introducción: Las anomalías vasculares (AV) de cabeza y cuello son una patología prevalente en niños, pero son poco frecuentes en adultos. La última clasificación descrita por la International Society for the Study of Vascular Anomalies (ISSVA) en 2018, propone dividirlas en tumores vasculares (TV) y malformaciones vasculares (MV) con una aproximación basada en la etiopatogenia, comportamiento biológico e inmunohistoquímico (IHQ). Objetivo: Describir la experiencia en el manejo de AV laríngeas (AVL) en adultos operados en los últimos 5 años en el Servicio de Otorrinolaringología (ORL) del Hospital Barros Luco Trudeau (HBLT) y realizar una revisión actualizada en cuanto a diagnóstico y manejo. Material y Método: Revisión retrospectiva y descriptiva de los casos de AVL en adultos operados del servicio de ORL del HBLT informadas por biopsia en el servicio de anatomía patológica del mismo hospital entre los años 2015 a 2020. Resultados: Se encontraron cinco casos de AVL. Los síntomas descritos fueron disfonía, odinofagia y disfagia. La sospecha diagnóstica se fundó en historia clínica, nasofibroscopia y estudio imagenológico, y se confirmó con biopsia posoperatoria. Todos los pacientes fueron resueltos de manera quirúrgica con leve preferencia por el láser CO2. No se registraron complicaciones ni signos de recidiva durante el seguimiento. Conclusión: Recomendamos el manejo quirúrgico de las AVL en adultos, realizando una resección completa de la lesión y su clasificación, según las recomendaciones de la ISSVA, con biopsia posoperatoria e inmunohistoquímica debido a la heterogeneidad de las clasificaciones previas.
Introduction: Head and neck vascular abnormalities (AV) are common alterations found in children, but rare in adults. The latest classification described by the International Society for the Study of Vascular Anomalies (ISSVA) in 2018, proposes dividing them into vascular tumors (TV) and vascular malformations (MV), based on their etiopathogenesis, biological and immunohistochemical behavior (IHC). Aim: To describe the experience in the management of laryngeal AV (AVL) of adults treated surgically on in the last 5 years in the Otolaryngology Service (ORL) of the Hospital Barros Luco Trudeau (HBLT). Material and Method: Retrospective and descriptive review of cases with histologically confirmed AVL in adults treated surgically in the ORL service of the same hospital between the years 2015 and 2020. Results: Five cases of AVL were found. The symptoms described were dysphonia, pharyngodine, and dysphagia. The diagnostic suspicion was based on clinical history, nasofibroscopy and imaging study, confirmed with post-operative biopsy. All patients were resolved surgically with a slight preference for the CO2 laser. No complications or signs of recurrence were recorded during the follow-up. Conclusion: We recommend surgical management of AVL in adults with a complete resection and their classification according to the recommendations of the ISSVA with postoperative and immunohistochemical biopsy, due to heterogeneity of previous classifications systems.

Resumo As malformações vasculares são anomalias que podem acometer veias, vasos linfáticos e artérias de forma isolada ou mista. Quando se apresentam de forma mista, com componentes venosos e linfáticos, são denominadas malformação venolinfática ou linfático-venosa, de acordo com sua constituição predominante. Embora seja um distúrbio benigno de bom prognóstico, é localmente invasivo, podendo levar a deformidade e havendo, ainda, a propensão de recorrência local. O presente artigo traz um caso de malformação venolinfática com localização incomum em borda lateral de língua, abordando-se a conduta clínica e o referencial teórico vigente.
Abstract Vascular malformations are vascular anomalies that can affect veins, lymphatic vessels, and/or arteries in isolated or mixed form. When they present in the mixed form with venous and lymphatic involvement, they are called venolymphatic or lymphatic-venous malformations, depending on their predominant component. Although these are benign disorders with good prognosis, they are locally invasive and may lead to deformity, while there is also a propensity for local recurrence. This article presents a case of venolymphatic malformation with unusual localization on the lateral border of the tongue, addressing the clinical conduct and the current theoretical framework.

Benign oral vascular lesions are anomalies characterized by the blood vessels proliferation or malformation and the treatment with the sclerosing agent ethanolamine oleate acts irrigating the vessel producing a sterile inflammatory response. The objective of this study was to report and discuss the results from treatment of benign oral vascular lesions with non-diluted ethanolamine oleate through the analysis of clinical records. The sample was composed by the selection of twenty-six patients (12 male and 14 female), with oral vascular malformations. All lesions were treated with intralesional injections of undiluted ethanolamine oleate. These patients attended in Oral Medicine outpatient clinic of the Federal University of Paraná between the years of 2011 to 2015. The average age was 60.65 years, with a higher prevalence for women. The majority of the individuals had one lesion and its location was mostly in the lower lip. The main complaint was about a physical discomfort. The lesions had the average size of 6.52 mm and received a median number of 2.32 applications. Only one patient reported feeling pain in the postoperative week. In most cases the resolution of the lesion was considered partial. Follow-up was obtained up to one month after the end of treatment. The sclerotherapy with undiluted ethanolamine oleate shows acceptable results in the treatment of small benign oral vascular lesions with a few minor side effects.
Las lesiones vasculares orales benignas son anomalías caracterizadas por la proliferación o malformación de los vasos sanguíneos y el tratamiento con el agente esclerosante etanolamina oleato actúa irrigando el vaso produciendo una respuesta inflamatoria estéril. El objetivo de este estudio fue informar y discutir los resultados del tratamiento de lesiones vasculares orales benignas con oleato de etanolamina no diluido a través del análisis de historias clínicas. La muestra estuvo compuesta por la selección de veintiséis pacientes (12 hombres y 14 mujeres), con malformaciones vasculares orales. Todas las lesiones fueron tratadas con inyecciones intralesionales de oleato de etanolamina sin diluir. Estos pacientes acudieron a la clínica ambulatoria de Medicina Oral de la Universidad Federal de Paraná entre los años 2011 a 2015. La edad promedio fue de 60,65 años, con una mayor prevalencia para las mujeres. La mayoría de los individuos tenían una lesión y su ubicación era principalmente en el labio inferior. La queja principal era sobre una molestia física. Las lesiones tenían un tamaño promedio de 6,52 mm y recibieron una mediana de 2,32 aplicaciones. Solo un paciente informó haber sentido dolor en la semana postoperatoria. En la mayoría de los casos, la resolución de la lesión se consideró parcial. El seguimiento se obtuvo hasta un mes después del final del tratamiento. La escleroterapia con oleato de etanolamina sin diluir muestra resultados aceptables en el tratamiento de pequeñas lesiones vasculares orales benignas con algunos efectos secundarios menores.

Vascular anomalies (VAs) include a group of distinct lesions, such as vascular system congenital malformations, as well as benign and malignant vascular tumors. These lesions may present similar clinical and histopathological features, leading to mistaken diagnoses and incorrect treatment choices. It is important that professionals responsible for monitoring the development of VAs conduct precise investigations and use the appropriate terminology. The human glucose transporter protein isoform 1 (GLUT1) has been proposed as a tool to aid in differential diagnosis between different VAs, given that it is a sensitive and specific marker for identification of infantile hemangiomas (HIs) in any organ. This article presents a review of the literature on this protein as an effective tool for identification and possible differential diagnosis between several VAs.
As anomalias vasculares (AVs) incluem um grupo de lesões distintas, como as más formações congênitas e os tumores vasculares benignos ou malignos. Estas lesões podem apresentar características clínicas e histopatológicas semelhantes, ocasionando equívocos diagnósticos e terapêuticos. Uma investigação precisa e o uso de terminologia adequada são fundamentais para as decisões do profissional responsável pelo acompanhamento da evolução de uma AV. A isoforma 1 da proteína humana transportadora de glicose (GLUT1) tem sido proposta como uma ferramenta auxiliar para o estabelecimento de diagnóstico diferencial entre AVs, uma vez que representa um marcador sensível e específico para a identificação de hemangiomas da infância de qualquer órgão. Este estudo objetiva fazer uma revisão da literatura acerca desta proteína como ferramenta eficaz na identificação e no possível diagnóstico diferencial entre as diversas AVs.

Las malformaciones vasculares son enfermedades raras ocasionadas por errores en el desarrollo embriológico de los vasos sanguíneos. Estas lesiones, junto con los tumores vasculares, constituyen las anomalías vasculares. En el caso de las malformaciones vasculares, éstas se denominan de acuerdo al vaso que conforma la lesión y se clasifican según las características del flujo en malformaciones de bajo o alto flujo. Si bien la mayor parte son diagnosticadas según criterios clínicos, algunas lesiones requieren de estudios complementarios tanto para el establecimiento de un correcto diagnóstico como para la evaluación de su extensión. La ecografía Doppler suele ser el estudio inicial para conocer las características hemodinámicas y contribuir al diagnóstico diferencial entre un tumor y una malformación vascular. La resonancia magnética (RM) es el mejor método para evaluar la extensión de las lesiones y su relación con estructuras adyacentes. El diagnóstico preciso del tipo de malformación vascular es importante por su pronóstico y tratamiento diferentes. La Radiología Intervencionista constituye uno de los pilares fundamentales en el manejo terapéutico. Es altamente recomendable un abordaje multidisciplinario dada la complejidad de estas lesiones, particularmente en la elección de las opciones terapéuticas y en el seguimiento clínico de los pacientes.
Vascular malformations: diagnostic clues for the radiologist. Vascular malformations are rare conditions resulting from the abnormal development of blood vessels. These lesions, together with vascular tumors, represent the vascular anomalies. Vascular malformations are named according to which type of vessel is affected and are classified into high- or low-flow malformations on the basis of flow characteristics. Most vascular malformations are diagnosed according to clinical criteria. However, some require imaging studies to confirm the diagnosis or assess its extension. Doppler ultrasound is the usual initial study for hemodynamic assessment and forits contribution to differential diagnosis between vascular tumors and malformations. Magnetic resonance imaging(MRI) is the best technique for evaluating the extent of the lesions and their relationship with adjacent structures. An accurate diagnosis of the type of vascular malformation is of importance because of the different prognosis and treatment. Interventional radiology is one of the cornerstones in the therapeutic management. A multidisciplinary approach is highly recommended given the complexity of these lesions, particularly for selecting therapeutic options and for the patient clinical follow-up.

Background: Vascular anomalies are prevalent in the general population and may produce significant impairment in quality of life. In recent years, minimally invasive interventional radiology techniques have become an efficient alternative for the treatment of these patients. The aim of this study was to present our experience in the management of vascular malformations with such techniques at Clínica Alemana in Santiago, Chile, and assess the satisfaction of patients with this management. Material and Methods: Evaluation of the follow-up of patients with vascular malformations treated in the Interventional Radiology Unit at our center since June - 2006 to June - 2009. Patients were classified according to the hemodynamics of the lesions (high vs low-flow). Complications and patient satisfaction with the treatment were assessed. Results: Eighty-seven patients (253 procedures) were included in the study, 36 men and 51 women, all with complete follow-up during the period of the study. Their average age was 20.6 years. In over 50 percent of the patients the vascular anomaly was located on the face or the lower extremities. Twenty-eight percent (25 patients) had a high-flow malformation (pure or mixed) and 62 (72 percent) had a low-flow lesion (vascular malformation, lymphangioma or mixed). On average, each patient underwent 2.9 procedures (1-10). There were 4 major complications (1.65 percent), one of which was predominantly cosmetic with necrosis in the area of the lesion. The average satisfaction rate was 7.95 (on a rating scale of 1 to 10). Satisfaction was significantly higher in patients with low-flow malformations (8.27) than in those with high-flow lesions (7.16). (p < 0.05) Discussion: Treatment of vascular malformations using interventional radiology techniques is an effective alternative, with good prospects of clinical improvement, patient satisfaction and low complication rates.

El objetivo del presente estudio es mostrar nuestra experiencia en el manejo de malformaciones vasculares con estas técnicas en la Clínica Alemana de Santiago y evaluar la satisfacción de los pacientes con este manejo. Material y Métodos: Evaluación del seguimiento de todos los pacientes con malformaciones vasculares tratados en la Unidad de Radiología Intervencional desde el año 2006 hasta junio del año 2009. Los pacientes fueron clasificados en base a la hemodinamia de la malformación vascular (alto flujo vs. bajo flujo). Se evaluaron las complicaciones, y se realizó una encuesta sobre la satisfacción de los pacientes con el tratamiento. Resultados: Ochenta y siete pacientes (253 procedimientos) fueron incluidos en el estudio, 36 hombres y 51 mujeres, todos con seguimiento completo en este periodo. La edad promedio de ellos fue de 20,6 años. En más del 50 por ciento de los pacientes la anomalía vascular se ubicó en la cara o extremidades inferiores. Un 28 por ciento (25 pacientes) presentó malformación de alto flujo (pura o mixta) y 72 por ciento (62 pacientes) de bajo flujo (malformaciones vasculares, linfangiomas o mixtas). En promedio, cada paciente se realizó 2,9 procedimientos (1-10). Del total de procedimientos realizados, hubo 4 complicaciones mayores (1,65 por ciento), una de ellas con secuelas estéticas producto de necrosis de la zona. El promedio de satisfacción fue de un 7,95 en una escala de 1 a 10, siendo significativamente mayor en pacientes con malformaciones de bajo flujo (8,27) que en los de alto flujo (7,16) (p < 0.05)...

INTRODUCTION: Venous malformations are the most frequent vascular malformation. Deep venous malformations are located in subcutaneous tissue or in the muscles. Percutaneous sclerotherapy is the treatment of choice, and the use of ethanol at low doses has not yet been described. OBJECTIVE: To analyze the results of treating Deep venous malformations patients with low doses of ethanol. METHODS: Thirty-nine patients treated between July 1995 and June 2007 were followed up prospectively over a median period of 18 months. Twenty-nine were female (74.4 percent) and 10 were male (25.6 percent), with ages ranging from 11 to 59 years (median of 24 years). All of the lesions affected limbs, and the main symptom reported was pain (97.4 percent). Each patient underwent fortnightly alcohol application sessions under local anesthesia on an outpatient basis. The lesions were classified into three groups according to size using nuclear magnetic resonance imaging: small, up to 3 cm (4 patients); medium, between 3 and 15 cm (27 patients); and large, greater than 15 cm (8 patients). RESULTS: The symptoms completely disappeared in 14 patients (35.9 percent) and improved in 24 (61.5 percent). The lesion size reduced to zero in 6 patients (15.4 percent) and decreased in 32 (82 percent). The median number of sessions was 7. There were no complications in 32 patients (82 percent), while 3 presented local paresthesia (7.7 percent), 2 superficial trombophlebites (5.1 percent), 1 skin ulcer (2.6 percent), and 1 case of hyperpigmentation (2.6 percent). CONCLUSION: Outpatient treatment for Deep venous malformations patients using ethanol at low doses was effective, with a low complication rate.

Congenital intrahepatic portosystemic venous shunt (IHPSVS) is rare vascular anomaly. We present one case of a 14- month male child who presented with global developmental delay. Child had high ammonia levels with low glutamine and high bile salts on the previous investigations and had history of neonatal seizures since day 13 of life. On admission, serum ammonia levels were elevated to 112μmol/L. Other laboratory investigations including liver and renal function test, and electrolytes were normal. He was, diagnosed to have IHPSVS on the basis of Doppler and CT, and treated by embolization with n-butyl cyanoacrylate (glue). A brief review of diagnostic modalities and endovascular management for the IHPSVS is presented including the present case.

OBJECTIVE: We wanted to evaluate the safety and feasibility of ethanol sclerotherapy for treating craniofacial venous malformations (CVMs). MATERIALS AND METHODS: From May 1998 to April 2007, 87 patients (40 men and 47 women; age range, 2-68 years) with CVMs underwent staged ethanol sclerotherapy (range, 1-21 sessions; median number of sessions, 2) by the direct puncture technique. Clinical follow up (range, 0-120 months; mean follow up, 35 months; median follow up, 28 months) was performed for all the patients. Therapeutic outcomes were established by evaluating the clinical outcome of the signs and symptoms in all patients, as well as the degree of devascularization, which was determined on the follow-up imaging, in 71 patients. RESULTS: A total of 305 procedures with the use of ethanol were performed in 87 patients. Follow-up imaging studies were performed for 71 of 87 patients. Twenty-three (32%) of the 71 patients showed excellent outcomes, 37 patients (52%) showed good outcomes and 11 patients (16%) showed poor outcomes. Ethanol sclerotherapy was considered effective for 60 patients. All the minor complications such as bulla (n = 5) healed with only wound dressing and observation. Any major complication such as skin necrosis did not develop. CONCLUSION: Percutaneous ethanol sclerotherapy is an effective, safe treatment for CVMs.

Vascular malformations are heterogenous angiodysplasias. The aim of this work is to study the epidemiological and clinical features of venous malformations [VM] as well as their multidisciplinary management. It is a retrospective study of patients having simple VM, seen at the multidisciplinary consultation of angiodysplasias of our hospital, over a 10 year period. This study included 99 patients having VM. A female predominance was noticed. Average age was 18.5 years. VM had mainly cephalic location. All VM were treated with percutaneous sclerotherapy. Aesthetic results were excellent in the cases of small VM size. VM are most frequent in cephalic region and cause aesthetic and functional handicaps. Percutaneous sclerotherapy is the treatment of choice for such a venous malformations, especially for small VM. VM are anomalies which can have serious complications. Their management has to be multidisciplinary in order to better precise the diagnosis and to take the adequate therapeutic decision
