Etiology of Hemoptysis in Children and Adolescents – Multicentric Retrospective Data (2012-2021) From Chennai

Objective: To analyze the etiology of hemoptysis in children and to correlate the severity of bleed with the etiology. Methods: This retrospective multicentre study reviewed data from inpatient units of four tertiary care public and private sector pediatric hospitals in Tamil Nadu. Methods: Inpatient case records of children (aged 2 month-15 years) treated for hemoptysis at the four institutions between April, 2012 and March, 2021 were identified, after ethical clearance from respective institutions. Data of children with underlying known bleeding disorders like hemophilia or platelet abnormality were excluded from the study. Hemoptysis was categorized as mild, moderate and severe Results: Of the 73 children who had presented with hemoptysis during the study period, 60 (82.2%) children had mild, 9 (12.3%) had moderate and rest had severe hemoptysis. Idiopathic pulmonary hemorrhage was the most common cause of hemoptysis. The common causes of mild hemoptysis in children were idiopathic pulmonary hemorrhage (n=15, 25%), pulmonary tuberculosis (n=12, 20%) and pneumonia (n=8, 13.3%). Congenital airway anomalies and vascular anomalies were more likely to present with moderate to severe bleed. Conclusion: Etiology of hemoptysis is broad and categorizing them into mild, moderate and severe may give a clue about the possible etiology, there by restricting to the required investigations.

Immunoexpression of proliferation and apoptosis markers in oral vascular anomalies

Abstract The biological behavior of lesions is highly dependent on the imbalance between their proliferative and apoptotic capacity. This study evaluated a correlation between the proliferative and apoptotic rates of different oral vascular anomalies (VAs) by analyzing the immunoexpression of proliferation (Ki-67) and apoptosis (Bcl-2 and Bax) markers in endothelial cells of 20 cases of GLUT-1 positive infantile hemangiomas (IHs), 20 cases of pyogenic granulomas (PGs) and 20 cases of vascular malformations (VMs). Immunoexpression analysis of Ki-67, Bcl-2 and Bax revealed a lower median percentage of positive cells in VMs cases compared to IHs and PGs cases (P <0.001). The Wilcoxon signed‐rank test showed significantly higher percentages of immunostaining for Bax than for Bcl‐2 in IHs (P = 0.048). In the group of PGs, a positive correlation was observed between the immunoexpressions of Ki-67 and Bax (r = 0.476; P = 0.034). Although oral IHs, PGs and VMs present similar clinical and histopathological features, each of these lesions has its etiopathogenic particularities. The results of this study suggest that different biological behaviors of VAs may be related to differences in the proliferative and apoptotic profiles of their endothelial cells.

Resumo O comportamento biológico das lesões é altamente dependente do desequilíbrio entre sua capacidade proliferativa e apoptótica. Neste estudo, avaliou-se se existe correlação entre as taxas proliferativas e apoptóticas de diferentes anomalias vasculares orais (AVs) analisando a imunoexpressão de marcadores de proliferação (Ki-67) e apoptose (Bcl-2 e Bax) em células endoteliais de 20 casos de hemangiomas infantis GLUT-1 positivos (HIs), 20 casos de granulomas piogênicos (GPs) e 20 casos de malformações vasculares (MVs). A análise de imunoexpressão de Ki-67, Bcl-2 e Bax revelou uma porcentagem mediana menor de células positivas nos casos de MVs em comparação aos casos de HIs e GPs (P <0,001). O teste de Wilcoxon mostrou porcentagens significativamente maiores de imunocoloração para Bax do que para Bcl-2 em HIs (P = 0,048). No grupo dos GPs, foi observada correlação positiva entre as imunoexpressões de Ki-67 e Bax (r = 0,476; P = 0,034). Embora HIs, GPs e MVs orais apresentem características clínicas e histopatológicas muito semelhantes, cada uma dessas lesões tem suas particularidades etiopatogênicas. Os resultados deste estudo sugerem que diferentes comportamentos biológicos dos AVs podem estar relacionados a diferenças nos perfis proliferativo e apoptótico de suas células endoteliais.

Actualización en clasificación y manejo de anomalías vasculares laríngeas en adultos

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.

What do Cochrane systematic reviews say about congenital vascular anomalies and hemangiomas? A narrative review

ABSTRACT BACKGROUND: Congenital vascular anomalies and hemangiomas (CVAH) such as infantile hemangiomas, port-wine stains and brain arteriovenous malformations (AVMs) impair patients' lives and may require treatment if complications occur. However, a great variety of treatments for those conditions exist and the best interventions remain under discussion. OBJECTIVE: To summarize Cochrane systematic review (SR) evidence on treatments for CVAH. DESIGN AND SETTING: Review of SRs conducted in the Division of Vascular and Endovascular Surgery of Universidade Federal de São Paulo, Brazil. METHODS: A broad search was conducted on March 9, 2021, in the Cochrane Database of Systematic Reviews to retrieve any Cochrane SRs that assessed treatments for CVAH. The key characteristics and results of all SRs included were summarized and discussed. RESULTS: A total of three SRs fulfilled the inclusion criteria and were presented as a qualitative synthesis. One SR reported a significant clinical reduction of skin redness by at least 20%, with more pain, among 103 participants with port-wine stains. One SR reported that propranolol improved the likelihood of clearance 13 to 16-fold among 312 children with hemangiomas. One SR reported that the relative risk of death or dependence was 2.53 times greater in the intervention arm than with conservative management, among 218 participants with brain AVMs. CONCLUSION: Cochrane reviews suggest that treatment of port-wine stains with pulsed-dye laser improves redness; propranolol remains the best option for infantile hemangiomas; and conservative management seems to be superior to surgical intervention for treating brain AVMs.

A 46-Year Retrospective Study of Oral Vascular Anomalies in a Brazilian Population

ABSTRACT: A retrospective study was performed to describe the demographic and clinicopathological characteristics of cases of vascular anomalies in a Brazilian population. The data of cases diagnosed as vascular anomalies over a period of 46 years, were retrieved from the archives of the Pathological Anatomy Service of the Department of Dentistry of Federal University of Rio Grande do Norte. Information about sex, age, race, diagnosis, location, and clinical characteristics was extracted. A database was created for analysis in the SPSS system and description of the results. The sample consisted of 597 cases categorized as follows: pyogenic granuloma (n = 454), infantile hemangioma (n = 57), vascular malformation (n = 37), lymphangioma (n = 20), hemangiolymph angioma (n = 10), vascular thrombus (n = 7), hemangio endothelioma (n = 5), angiofibroma (n = 1), hemangioendothelio sarcoma (n = 1), and Kaposi sarcoma (n = 5). Overall, there was a predominance of females (64.2 %), white race (54.2 %), and patients in the 3rd and 4th decades of life. Most cases affected the gingiva/ ridge (44.75 %), had a red/reddish color (60.07 %), sessile implantation (52.4 %), soft consistency (52.7 %) and nodular appearance (53, 9 %), and were non-hemorrhagic (51.3 %) and asymptomatic (76.6 %). The demographic and clinicopathological findings obtained for most of the vascular lesions analyzed are similar to those reported in published studies involving other populations. Knowledge of the particularities of these disorders is important for appropriate diagnosis and treatment decision.

Anomalías Vasculares de la Cavidad Oral: Revisión de la Clasificación y Tratamiento Aplicado a dos Casos Clínicos / Vascular Anomalies of the Oral Cavity: Review of Classification and Treatment Applied to Two Clinical Cases

RESUMEN: Las anomalías vasculares de cabeza y cuello son un grupo de lesiones que afectan vasos sanguíneos y linfáticos donde el tratamiento sigue siendo un desafío. La clasificación actualizada de anomalías vasculares de cabeza y cuello es la clasificación de Mulliken modificada, que las subdivide en a) tumores vasculares y, b) malformaciones vasculares. En este reporte, presentamos dos casos clínicos de pacientes de sexo masculino, con diagnóstico de anomalías vasculares que afectan al labio y paladar duro, diagnosticados como malformación arteriovenosa y malformación venosa, respectivamente. Dichas lesiones remitieron completamente mediante tratamientos conservadores (agentes esclerosantes) y/o quirúrgicos (exéresis quirúrgica completa de la lesión) logrando una remisión completa. Consecutivamente, presentamos una revisión de la literatura enfocado a la clasificación actual, enfoques terapéuticos actuales y futuros.

ABSTRACT: Vascular anomalies of the head and neck are a group of lesions that affect blood and lymph vessels where treatment remains a challenge. The updated classification of head and neck vascular anomalies is the modified Mulliken classification, which subdivides them into a) vascular tumors and b) vascular malformations. In this report, we present two clinical cases of male patients, with diagnosis of vascular anomalies affecting the lip and hard palate, diagnosed as arteriovenous malformation and venous malformation, respectively. These lesions were completely treated with conservative (sclerosing agents) and/or surgical (complete surgical exeresis of the lesion) treatments, achieving a complete remission. Consequently, we present a review of the literature focused on the current classification, current and future therapeutic approaches.

Classification of Vascular Anomalies Using Clinico- Radiological Parameters – Is It Sufficient?

To classify vascular anomalies using clinico-radiological parameters. Settings: Government Medical College Srinagar and Army Hospital Research and Referral New Delhi. Methods: 129 cases of vascular anomalies were studied and classified using clinical and radiological methods from March 2011 to June 2018. Outcome: Vascular anomalies were broadly classified into vascular tumours and vascular malformations and these anomalies were further sub-classified based on clinical and radiological parameters. Results: Among 129 vascular anomalies studied there were 51 vascular tumours which included 50 hemangiomas (H) and 1 case of pyogenic granuloma (PG). Among Hemangiomas there were 34 Hemangiomas of Infancy (HOI) and 16 Congenital Hemangiomas (CH). Among HOI there were 26 Simple (Localized-17, Segmental-2, Indeterminate-6, Multifocal-1), 8 complex visceral hemangiomas (Liver-2, Subglottic-2, Parotid-4). Among Congenital Hemangiomas there were 4 Rapidly Involuting Congenital Hemangiomas (RICH) and 12 Non involuting congenital hemangiomas (NICH). There were 78 vascular malformations which included 51 slow flow malformations and 27 fast flow malformations based on colour doppler studies. Among slow flow there were 42 Simple {2 Capillary Malformations, 26 Venous Malformations (VM), 14 Lymphatic Malformations (LM), 4 Combined (2 each of Lymphohemangiomas - LH and Lymphovenous Malformations – LVM} and 5 Complex-combined (4 Klipple Trenaunay Syndrome – KTS and 1 case of Blue Rubber Bleb Nevus Syndrome - BRBNS). Among fast flow there were 6 simple (Nasopharyngeal Angiofibromas), 20 combined (Arteriovenous Malformations - AVM) and 1 Complex combined malformation (Sturge Weber Syndrome - SWS). Conclusion: Newborn with birthmark should always be documented by the attending health care provider at birth and referral to an expert for proper evaluation and careful parental/Guardian counseling. Doppler US should be the first line of investigation in broadly classifying vascular anomalies whereas CT Scan, MRI/MRA/MRV, Angiography, Venography help in further sub-classification. Some confusion still persists in classifying few lesions like Lympho-hemangioma (LH), Complex combined Malformations (Syndromes) like Sturge Weber Syndrome (SWS), Blue Rubber Bleb Nevus Syndrome (BRBNS), and Nasopharyngeal Angiofibroma (NPA).

Vascular Anomaly: An Updated Review / 임상소아혈액종양

Vascular anomalies comprise a heterogeneous group of disorders characterized by abnormal growth or development of blood vessels. Diagnosis of vascular anomalies is often challenging due to the large variety of conditions, which exhibit phenotypic heterogeneity and a wide range of symptomology and severity. Accurate diagnosis is crucial for appropriate evaluation and management, often requiring multidisciplinary specialists. Recent interdisciplinary collaboration has led to collaborative studies and their outcomes are being prospectively evaluated. While there is still a role for surgical intervention in various vascular anomalies, discoveries of pharmacologic agents effective in treating vascular anomalies have broadened our medical therapeutic options. This paper focuses on vascular anomaly issues often seen by the pediatricians and reviews the clinical pearls on infantile hemangiomas, lymphatic malformations, venous malformations, and arteriovenous malformations.

Study Of M1 Segment Of Middle Cerebral Artery In Human Cadaveric Brains With Clinical Implications Of Its Early Branches

Background: Human brain gets its nutrition from carotido and vertebro-basilar system of vessels. MCA, being thelarger terminal branch of ICA supplies the cortical areas of brain concerned with speech and language. It is themost commonly involved artery in cerebro-vascular accidents as in stroke which is characterised by suddenonset of focal neurological deficit. The anatomical study is of utmost important to neurovascular surgeons.Materials and methods: The present study was undertaken in 140 cadaveric human brain hemispheres of 70formalin fixed brains from Department of Anatomy and Forensic medicine of Mysore medical college and ESICMC and PGIMSR, Bangalore. Fixed brains were sagitally bisected into right and left halves by brain cutting knife.Meninges were cleared and MCA was identified which was the larger and direct branch of ICA. Measurements ofICA and MCA was taken using thread and measuring scale. LSAs arising from MI segment MCA were counted usinghand lens. Any early branch if present was noted. Angle was noted between M1 and M2 segment. Presence of anyanomalies were studiedResults: The mean of length of M1 was found slightly more on the left side (2.09 cms) in comparison to right side(1.90 cms). The mean diameter of M1 segment of MCA was more on the left side (0.352 cms), in comparison toright side (0.317 cms). The mean diameter of left MCA (0.352 cms) and left ICA (0.359 cms) were of the same size.The mean diameter of right MCA (0.317 cms) and right ICA (0.323 cms) were almost of the same size. The numberof LSAs were more on left side (5.9) in comparison to right side (5.67). Early branches were found to be more onright side (5) than left side (3). The angle was observed to be acute in all specimens.Conclusion: This study was undertaken due to its clinical significance to stroke. Observations made on MCArevealed greater length of MCA carrying greater proportion of blood flow to the left side – a feature whichsupports the concept of vascular asymmetry. The knowledge of early branch arising from proximal segment ofMCA is helpful for neurovascular surgeons to make a fairer decision in planning the treatment for any neurovsculardisorders. The authors felt the necessity of documentation of data inferred by our study as there are very fewarticles on MCA found published in Indian literature.

Malformación vascular capilar y venosa en la mano. Reporte de caso de una extraña patología quirúrgica / Vascular capillary and venous malformation in the hand. Case report of a strange surgical pathology

Resumen Introducción: Las anomalías vasculares representan un amplio panorama de distintas lesiones donde los tumores son los más frecuentes. Las malformaciones vasculares suelen presentarse en etapas tardías de la vida secundarias al lento crecimiento y a los síntomas que padecen los pacientes. Debe de darse un manejo multidisciplinario donde el diagnóstico es la piedra angular. Los casos de malformaciones venosas o linfáticas suelen tratarse mediante la resección de la malformación en su totalidad. Presentación del caso clínico: Varón de 35 años de edad quién presenta aumento de volumen y dolor de 3 meses de evolución en la mano derecha. A la exploración física se observa una masa en la región tenar de dicha mano, con bordes bien definidos de aproximadamente 3 × 3 cm, no móvil, adherida a planos profundos, dolorosa a palpación, con hiperestesias en trayecto del nervio mediano. Se realizaron ultrasonido Doppler y resonancia magnética, los cuales sugirieron una lesión vascular. Se realizó exploración quirúrgica y se observó una lesión vascular adherida a las estructuras nerviosa y tendinosa, las cuales se liberaron y se extrajo la tumoración. Se envió la pieza quirúrgica a patología, que reportó hemangioma capilar y venoso. Conclusiones: Las malformaciones vasculares mixtas (venoso y capilar) en la mano son una entidad poco frecuente que requiere de un manejo quirúrgico preciso. Estas lesiones generan síntomas asociados al aumento de volumen, entre los que destacan: dolor, disminución del rango de movimientos. El tratamiento quirúrgico se asocia a una mejoría de los síntomas.

Abstract Introduction: Vascular anomalies in the hand represent a rare disease that needs an accurate diagnosis and prompt surgical treatment. One of the uncommon anomalies is the mixed vascular one. The diagnosis of these malformations is clinical but radiological studies such as magnetic resonance and Doppler ultrasound are mandatory. Once the diagnosis is made, surgery is the next and final step. Recurrence is rare when the entire tumor is resected. Clinical Case Study: A 35-year-old male presented with an increase in volume and pain of three months of evolution in the right hand. On physical examination, a mass in the righthand thenar region was observed, with well-defined edges of approximately 3 x 3 cm, not mobile, adhered to deep planes, painful to palpation, with hyperesthesias in the median nerve pathway. A magnetic resonance and a Doppler ultrasound were applied showing a well-circumscribed tumor. The patient underwent surgery and the whole vascular malformation was removed with no damage of neighbor structures. Pathology reported a venous and capillary hemangioma. Conclusions: Mixed vascular malformations in the hand are uncommon pathologies that require a correct diagnosis and a prompt surgical resolution. The most frequent symptoms associated with these tumors are: tenderness, pain and limitation in the movement of the hand. Surgical treatment is always recommended.

Clinical and anatomic analysis of children with congenital bridging bronchus malformation / 中华实用儿科临床杂志

Objective To analyze the clinical and anatomic characteristics of bridging bronchus (BB) malformation in children,and to explore its diagnostic strategy,treatment and risk factors.Methods A retrospective study was performed in 23 pediatric patients with BB who were admitted to Guangzhou Women and Children's Medical Center form May 2010 to October 2016.All their clinical features,imaging examination,treatment and prognosis were reviewed and analyzed.Results (1) Among the 23 patients with BB,15 were males and 8 were females.The age range of onset was 0 to 4 years old with a median age of 3.17 months.(2)The main clinical manifestations were cough (23/23 cases,100.0％),recurrent wheezing (20/23 cases,87.0％),cyanosis (8/23 cases,34.8％) and feeding diffficulty/slow body weight growth (6/23 cases,24.6％).(3) There were 17 cases of type Ⅰ and 4 cases of type Ⅱ according to Wells,and the other 2 cases were anterior BB.There were 2 cases with atypical anatomical morphology in type Ⅰ and type Ⅱ respectively.(4) Twenty-one cases were associated with bronchial stenosis in which the origin of left main bronchus complicated with BB stenosis was the most common(5 cases).Bronchoscopy revealed bronchomalacia in 5 of the 16 patients.Sixteen patients associated with cardiac or vascular anomalies,11 of whom were compound anomalies,and the most common type was sling left pulmonary artery (SLPA) (12 cases).(5) Nine of 12 patients with SLPA received surgical management,ages ranging from 1 month to 8 years old.The respiratory symptoms remitted gradually or disappeared from 4 to 17 months after surgical management.Two died and one has been lost to follow-up among the remaining 3 patients with SLPA.Conclusions BB is a rare tracheobronchial malformation that is often associated with stenosis or bronchomalacia,and cardiac or vascular anomalies.The severity of the disease mainly depends on whether there is airway stenosis or malacia and its extent.The definitive diagnosis of BB requires the combination of different imaging modalities.The combination with simple SLPA could get better curative effect.

Vascular Anomalies: A 3-Year Review in the Paediatric Institute Hospital Kuala Lumpur Between 2013 And 2015

Introduction:Vascular anomalies, regardless of tumour or malformation, may result in significant morbidity. Thediagnosis of vascular anomalies in the paediatric group is always challenging. We aim to describe thepattern of vascular anomalies referred to the Paediatric Institute Kuala Lumpur Hospital (PIKLH).Methods:This is a 3-year retrospective review on vascular anomalies among children referred to PIKLH between2013 and 2015.Results:There were 289 children; male to female ratio of 1:2.1; aged from birth to 14 years with median age of5 months recruited. The referring diagnoses included haemangioma (71.3%), capillary malformation(13.8%), lymphatic malformation (1.7%), kaposiform hemangioendothelioma (1.0%) and others. Ahundred and sixty-one (55.7%) had lesions located at the head and neck region, followed by trunk(14.2%), lower limbs (9.3%), upper limbs (7.6%), perineum (3.8%) and multiple sites (6.9%). In 197patients (68.2%), there were no further investigations performed, 13.5% had ultrasonography, 7.3%had MRI, 4.8% had both ultrasonography and MRI; 4.1% had skin biopsy, 0.3% had angiogram.The final diagnoses were haemangioma (72.3%) of which 10 were ulcerated; capillary malformations(17.6%), combined vascular malformations (2.4%), kaposiform hemangioendothelioma (2.8%),lymphatic malformations (2.1%); venous malformations (1.4%); tufted angioma (1.0%) andarteriovenous malformations (0.3%). One hundred and nine patients (37.7%) received beta-blockers;71(24.6%) underwent laser, 16(5.5%) received sirolimus, 9(3.1%) received systemic corticosteroidswith vincristine, 4(1.4%) had systemic corticosteroids, 3(1.0%) had excision and 2(0.7%) hadsclerotherapy. The remaining patients were put under observation.Conclusion:Three-quarters of the vascular anomalies referred were hemangioma followed by vascularmalformations. Vascular anomalies have a large variation in clinical presentation. Expertise inthe diagnosis and management modalities are essential to achieve optimum outcomes. Thereforevascular anomalies are best managed in a multidisciplinary setting.

Malformaciones vasculares: manejo mediante técnicas de radiología intervencional y satisfacción de los pacientes / Vascular malformations: interventional radiology management and assesment of patient satisfaction

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.

Introducción: Las anomalías vasculares son una patología frecuente en la población general, y son causa de deterioro de la calidad de vida de los pacientes que las padecen. En los últimos años, las técnicas mínimamente invasivas de radiología intervencional se han convertido en una alternativa eficaz para el tratamiento de estos pacientes. 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)...

Ultrasonografía Doppler-color en el diagnóstico de las anomalías vasculares de las partes blandas superficiales en pediatría / Color Doppler ultrasonography in the diagnosis of vascular anomalies of the superficial soft tissue in children

Las anomalías vasculares de las partes blandas superficiales son frecuentes en el niño y se han clasificado en hemangiomas y malformaciones vasculares, según sus manifestaciones clínicas y hallazgos histológicos. La mayoría corresponde a hemangiomas, se presenta en el recién nacido, desaparece espontáneamente con el tiempo y sólo algunos de ellos requerirán de evaluación médica. Es importante especificar el tipo de lesión vascular para definir el tratamiento, lo que en la mayor parte de los casos es posible con los hallazgos clínicos. Sin embargo, a veces es necesario recurrir a estudios de imágenes para precisar el diagnóstico y los métodos más utilizados son la Ultrasonografía (US) Doppler-color; Resonancia magnética (RM) y Angiografía. La US Doppler-color es un método sencillo, inocuo, no invasivo, que permite diferenciar las lesiones superficiales de aquellas profundas y además permite evaluar la vascularización de la lesión y, de esta manera, lograr una adecuada aproximación diagnóstica. También permite seleccionar aquellos casos que requerirán de métodos más sofisticados, como RM o angiografía. El objetivo de esta revisión es mostrar la utilidad de la US Doppler en el estudio de las anomalías vasculares de las partes blandas superficiales en el niño.

Vascular anomalies of superficial soft tissues are frequent in children and have been classified in hemangiomas and vascular malformations, depending on clinical and histological findings. Most correspond to hemangiomas, present in the newborn period, which disappear spontaneously with time and only some may require an imaging evaluation. It is important to specify the type of vascular anomaly in order to define management, which in most cases is possible with just clinical findings. Nevertheless, some cases may require imaging studies to define diagnosis, and the most utilized methods are Doppler ultrasonography (US), magnetic resonance Imaging (MRI) and angiography. Doppler US is a non invasive, harmless and simple method which allows to differentiate between deep and superficial lesions. It also permits to evaluate vascularization and in this manner; achieve an adequate diagnosis and select those cases that will require more sophisticated methods like MRI or angiography. The main objective of this review is to show the role of Doppler US in the study of superficial soft tissue vascular anomalies in children.

Improvement in Diagnostic Accuracy of Hemangioma and Vascular Malformation through Multidisciplinary Clinic

PURPOSE: It is difficult to provide accurate diagnosis and proper treatment for vascular anomalies, because vascular anomalies have a wide spectrum of lesion with various symptoms. Furthermore, vascular anomalies often require the services of a wide range of specialists. So, many patients have been discouraged by the lack of expertise and treatment options available to them. In this study, we aimed to describe the scope of the Vascular Malformation clinic (VAM clinic), a multidisciplinary clinic for hemangioma and vascular malformation patients and investigate of diagnostic accuracy of VAM clinic. METHODS: 68 patients have included in a retrospective, medical record review study in the VAM clinic from may 2002 to august 2009. Data included the types of diagnoses of patients seen in the clinic, locations of lesions, comparison of accuracy of diagnoses at other clinic and initial diagnoses at VAM clinic and types of recommended treatments. RESULTS: Initial diagnosis at VAM clinic showed 94.2% accuracy, while diagnosis at other clinic only showed 12.5% accuracy. Head and neck is most frequently occurred lesions in patients of VAM clinic. And VAM clinic is able to provide various and proper treatments to patients. CONCLUSION: Hemangiomas and vascular malformations can present with various medical problems. VAM clinic, the multidisciplinary clinic provided accurate diagnoses and proper treatments to patients.

Anomalías vasculares de partes blandas: imágenes diagnósticas / Vascular anomalies of soft tissues: diagnostic images

Vascular anomalies include different pathologies as hemangiomas and vascular malformations, however they usually are reported together and confusion is created. Mülliken and Glowacki proposed a classification posteriorly, modificated, adapted and actually in use. Unfortunately is not sufficiently known for our radiologist. Classification and imaging correlation of soft-tissue vascular anomalies are revised, since a exact diagnosis is a great value for appropriate treatment and prognosis.

Las anomalías vasculares han sido tradicionalmente tratadas en conjunto aun cuando engloban patologías tan diferentes como hemangiomas y malformaciones vasculares. La clasificación dada a conocer por Mülliken y Glowacki, modificada posteriormente, no es suficientemente conocida ni usada en nuestro medio. Se revisa la clasificación actual y la correlación con imágenes de aquellas anomalías vasculares situadas en partes blandas, dada la importancia que tiene un correcto diagnóstico para la terapéutica y pronóstico de los pacientes con estas lesiones.
