Síndrome congénito de Klippel-Trenaunay-Weber: caso clínico / Congenital Klippel-Trenaunay-Weber syndrome: clinical case

RESUMEN: El síndrome de Klippel-Trenaunay-Weber (SKTW) es una enfermedad congénita poco frecuente caracterizada por hipertrofia de un miembro que afecta a los huesos y a las partes blandas, con extensos angiomas planos, várices y otras anomalías vasculares, como fístulas arteriovenosas. Su incidencia es de 1:100.000 personas. El objetivo fue describir un caso raro de SKTW bilateral, confirmado con hallazgos clínicos e imagenológicos en un niño de 9 años de edad, de sexo masculino, con antecedentes de sangrado digestivo bajo, herniorrafía inguinal izquierda y orquidopexia ipsilateral. En ambos miembros inferiores se identificaron lesiones hemangiomatosas e hipertrofia muscular y edema en miembro inferior izquierdo con ausencia de segundo y tercer dedos del pie izquierdo por antecedente quirúrgico de amputación. Adicionalmente, presentaba adenopatías cervicales e inguinales. Dentro de los hallazgos radiográficos importantes, se observó una cortical ósea delgada en el fémur del miembro inferior izquierdo. El SKTW afecta típicamente a los miembros inferiores de forma unilateral; este es un caso infrecuente de afección bilateral (con predominio izquierdo). Algunos pacientes, registran compromiso visceral con hemorragia digestiva baja, además de alteraciones genitourinarias, presentes en el 30% de los casos. La presentación de adenopatías es inusual.

SUMMARY: Klippel-Trenaunay-Weber syndrome (KTWS) is a rare congenital disease characterized by limb hypertrophy affecting bones and soft tissues, with extensive flat angiomas, varicose veins, and other vascular abnormalities, such as arteriovenous fistulas. Its incidence is 1: 100,000 people. The aim of this work was to describe a rare case of bilateral KTWS, confirmed with clinical and imaging findings in a 9-year-old male, with a history of lower gastrointestinal bleeding, left inguinal herniorrhaphy and ipsilateral orchidopexy. In both lower limbs, hemangiomatous lesions and muscle hypertrophy were identified, and in the left lower limb edema was identified with absence of the second and third toes due to a surgical history of amputation. Additionally, the patient presented cervical and inguinal lymphadenopathy. Among the important radiographic findings, in the left lower limb femur a thin bony cortex was observed. KTWS typically affects the lower limbs unilaterally; this is an infrequent case of bilateral affection (predominantly left). Some patients have visceral involvement with lower gastrointestinal bleeding, as well as genitourinary alterations, present in 30 % of cases. The presentation of lymphadenopathy is unusual.

Síndrome de Klipper-Trenaunay-Weber con compromiso vesical y uterino tratado por vía endoscópica y endovascular / Klippel-Trenaunay-Weber syndrome with vesical and uterine involvement treated by endoscopic and endovascular routes

El síndrome de Klippel-Trenaunay-Weber (SKTW) es una rara malformación venosa que, en general afecta a los miembros inferiores y, más raramente, a los superiores. Se caracteriza por formaciones angiomatosas cutáneas, várices e hipertrofia del miembro afectado. El compromiso genitourinario es sumamente infrecuente. Se presenta el caso de una paciente de 14 años. Ingresó por hematuria macroscópica de 48 h de evolución y metrorragia con grave compromiso hemodinámico. Se encontraba en estudio por presentar un hemangioma en el miembro inferior izquierdo que se extendía hasta la región pelviana. La uretrocistofibroscopía demostró la presencia de múltiples lesiones angiomatosas diseminadas en forma amplia en la vejiga, algunas de ellas con sangrado activo. La angioresonancia mostró una voluminosa formación hipervascularizada en contacto con la pared vesical a la cual desplazaba y fístulas arteriovenosas a nivel pelviano y en el miembro inferior izquierdo confirmando el diagnóstico etiológico. Se realizó una embolización arterial selectiva de los territorios ilíacos interno y externo e inmediatamente después una endocoagulación láser de los focos angiomatosos sangrantes. La hematuria remitió completamente en las 24 h posteriores al procedimiento. La metrorragia asociada al SKTW fue controlada mediante la utilización de análogos LHRH y progestágenos.

Klippel-Trenaunay-Weber syndrome (KTWS) is a rare venous malformation that generally affects the lower limbs and, more infrequently, the upper limbs. It is characterized by cutaneous angiomatous formations, varicose veins and hypertrophy of the affected limb. The involvement of the genitourinary tract is extremely infrequent. We expose the case of a 14 years old female patient who was admitted for macroscopic hematuria of 48 hours of evolution and metrorrhagia with severe hemodynamic decompensation. The patient was under study for presenting a hemangioma in the lower left limb that extended to the pelvic region. Urethrocystofibroscopy showed the presence of multiple wide-spread angiomatous lesions in the bladder, some of them with active bleeding. The angio-resonance showed a voluminous hypervascular formation in contact with the bladder wall showing several arteriovenous fistulas at the pelvic level and in the left lower limb confirming the etiological diagnosis. A selective arterial embolization of the internal and external iliac territories was performed and then, a laser endocoagulation of the bleeding angiomatous foci was carried out. The hematuria completely stopped within 24 hours later of the procedure. The metrorrhagia associated with KTWS was controlled by the use of LHRH analogs and progestogens.

Inverse klippel-trenaunay syndrome / Síndrome de klippel-trenaunay inverso

ABSTRACT Objective: To report a rare case of inverse Kipplel-Trenaunay. Case description: A 16-year-old girl with a grayish-depressed plaque on her left thigh. Angioresonance showed a vascular malformation affecting the skin and subcutaneous tissue. Comments: Inverse Klippel-Trenaunay is a Klippel-Trenaunay syndrome variation in which there are capillary and venous malformations associated to hypotrophy or shortening of the affected limb. Modifications on the limb's length or width result from alterations in bones, muscles, or subcutaneous tissues. It has few described cases. Further clinical and molecular studies must be performed for a proper understanding.

RESUMO Objetivo: Relatar um caso raro de Klippel-Trenaunay inverso.

Pode envolver acometimento ósseo, muscular ou subcutâneo, modificando o comprimento ou a circunferência do membro. Há poucos casos descritos, e mais estudos clínicos e moleculares precisam ser realizados para seu correto entendimento.

Síndrome de Klippel Trenaunay Weber y embarazo / Klippel Trenaunay Weber Syndrome and Pregnancy

RESUMEN Introducción: El síndrome de Klippel Trenaunay Weber es una enfermedad vascular congénita, de causas desconocidas, caracterizada por hemangiomas planos, crecimiento excesivo de huesos y tejido blando, y venas varicosas. Cuando se asocia al embarazo incrementa la morbilidad y mortalidad materna y fetal. Objetivo: Describir dos casos clínicos de gestantes con este síndrome las cuales fueron atendidas en el Hospital Ginecobstétrico Docente "Ramón González Coro" en La Habana, Cuba. Métodos: Estudio descriptivo, retrospectivo, de dos casos mediante técnica de recolección de información, análisis de la historia clínica y búsqueda de literatura actualizada. El mismo se efectuó conforme a las reglamentaciones y principios éticos existentes para la investigación en humanos. No fue necesario que las pacientes ofrecieran su consentimiento informado. Presentación de casos: Los dos casos presentados fueron gestantes adolescentes a las cuales se les dio seguimiento en consulta multidisciplinaria y se les realizó cesárea a las 38 semanas, la primera por riesgo de sangrado por las varicosidades pelvianas y la segunda por indicación neurológica. Se obtuvieron en ambos casos recién nacidos femeninos, de 2620 y 3200 gramos respectivamente y en buenas condiciones. Conclusiones: Debe realizarse una correcta anamnesis durante los controles prenatales para identificar los factores de riesgo que se relacionan con esta entidad que es poco frecuente, pero está relacionada con una gran morbilidad. Es indispensable la actuación en equipo y la evaluación integral de estos casos por un grupo especializado de angiólogos, ginecobstetras, anestesistas, cirujanos, clínicos, y de otras especialidades, para lograr un resultado óptimo(AU)

ABSTRACT Introduction: Klippel Trenaunay Weber syndrome is a congenital vascular disease, of unknown causes, characterized by flat hemangiomas, overgrowth of bones and soft tissue, and varicose veins. When associated with pregnancy, it increases maternal and fetal morbidity and mortality. Objective: To describe two clinical cases of pregnant women with this syndrome, which were treated at the Ramón González Coro Gynecobstetric Teaching Hospital in Havana, Cuba. Methods: A descriptive, retrospective study of two cases using the information collection technique, analysis of the medical history, and search for updated literature. It was carried out in accordance with existing regulations and ethical principles for human research. Patients were not required to offer their informed consent. Case reports: The two cases presented were pregnant adolescents who were followed up in a multidisciplinary consultation and underwent caesarean section at 38 weeks, the first due to risk of bleeding as result of pelvic varicosities and the second due to neurological indication. In both cases, female newborns, 2620 and 3200 grams respectively, were obtained in good conditions. Conclusions: Correct anamnesis must be carried out during prenatal controls to identify the risk factors that are related to this entity, which is rare, but is related to high morbidity. Team action and comprehensive evaluation of these cases, by a specialized group of angiologists, gynecologists, anesthetists, surgeons, clinicians, and other specialties, are essential to achieve an optimal result(AU)

Manifestações oftalmológicas de Síndrome de Klippel Trenaunay / Ophthalmological manifestation of the Klippel Trenaunay Syndrome

RESUMO A Síndrome de Klippel-Trenaunay (SKT) é uma doença congênita rara, com maior prevalência no sexo masculino e incidência de 2-5:100.000. Apresenta-se, na forma clássica, como a tríade de manchas vinho porto, hipertrofia de membros e malformação venosa e/ou linfática. O diagnóstico é essencialmente clínico e devido à complexidade da síndrome, de natureza progressiva e ampla variedade de apresentações clínicas, os pacientes devem ser tratados de forma individualizada por uma equipe multidisciplinar. Alterações oftalmológicas associadas à SKT incluem anormalidades vasculares da órbita, íris, retina, coroide e nervo óptico. Relato de caso: Paciente de 23 anos, sexo feminino, portadora de SKT, em acompanhamento no Centro da Visão - Universidade Federal do Paraná, com queixa de diminuição da acuidade visual em olho direito. A paciente apresentava manchas vinho porto em dimidio direito e hipertrofia de membros ipsilateral. Foi diagnosticado glaucoma e realizados exames complementares oftalmológicos a fim de avaliar o grau de comprometimento dos campos visuais e o fundo de olho. A visão com a melhor correção foi de 20/100 OD e foi de 20/20 OE. À fundoscopia, constatou-se aumento da escavação do nervo óptico à direita - 0,75 x 0,90 mm. Optou-se por tratamento clínico com Cloridrato de Dorzolamida, Latanoprosta, Brimonidina e Timolol, com bons resultados a longo prazo - a tonometria de aplanação mostrou 19 mmHg OD e 15 mmHg OE, apesar da dificuldade na estabilização da doença. Conclusão: Relatos demonstram que os resultados dos tratamentos clínico e cirúrgico do glaucoma em associação à SKT são insatisfatórios quando comparados a outros tipos de glaucoma - o controle clínico não é possível em cerca de 1/3 dos pacientes, e o manejo cirúrgico tem alto índice de complicações. São necessários estudos mais expressivos que estabeleçam a correlação entre glaucoma e SKT e embasem o tratamento de escolha.

ABSTRACT The Klippel-Trenaunay Syndrome (KTS) is a rare congenital disease, which the prevalence is higher in males, and its incidence of 25:100,000. It is presented in its classic form as the triad of port-wine stains, enlarged limbs and venous and / or lymphatic malformation. The diagnosis is essentially clinical and due to the complexity of the syndrome, the progressive characteristic and the wide variety of clinical presentations, a multidisciplinary team should treat patients individually. The ocular changes associated with KTS include vascular, orbit, iris, retina, choroid and optic nerve abnormalities. Case report: A 23-year-old female patient, carrier KTS, being followed at Vision Center - Federal University of Paraná, complaining of decreased visual acuity in the right eye. The patient had port-wine stains in right hemibody and hypertrophy of ipsilateral members. Glaucoma was diagnosed and eye exams were performed to assess the degree of impairment of visual fields and fundus. The best correction was checked at 20/100 OD and 20/20 OS. At fundoscopy, there was increased excavation of the optic nerve right - 0.75 x 0.90 mm. Clinical treatment was chosen with Dorzolamide Hydrochloride, Latanoprost, Brimonidine and Timolol, presenting good long-term results - the tonometry showed 19 mmHg OD and 15 mmHg OS, despite the difficulty in stabilizing the disease. Conclusion: Reports have shown that the results of clinical and surgical treatments of glaucoma in association with KTS are unsatisfactory compared to other types of glaucoma - clinical control is not possible in about 1/ 3 of patients and the surgical management has a high rate of complications. Significant studies are needed to establish the correlation between glaucoma and KTS, and base the treatment of choice.

Clinical Features of Varicose Vein in Pediatric Population / 소아외과

PURPOSE: Varicose veins requiring operative treatment have been more common recently, but there are not enough studies among children dermographics because most patients belong to the adult population. We concentrated on varicose vein of under 18 years old, and here intend to report cases of our clinical experiences. METHODS: From January 2003 until December 2014, there were 6 children under 18 years old who required varicose vein management. Data was collected by the investigation of medical records retrospectively, including preoperative symptoms, diagnostic tools, treatment methods, results of treatment, and complications. RESULTS: The mean age was 11 years (range, 3-17 years), and gender ratio was 1:2 (2 male, 4 female). The involved legs were on the right in 3 cases, on the left in 2 cases, and on both in 1 case. The most common symptoms were venous bulging and tortuosity in 6 cases, and other symptoms were Klippel-Trenaunay-Weber syndrome in 2 cases, pain and fatigue in 1 case, port-wine stain in 1 case, and telangiectasia in 1 case. Duplex sonography was performed to confirm venous reflux in all cases. The additional venography was performed to check for anatomical variation in 1 case, and three-dimensional CT in 2 cases. Treatments were high ligation and stripping in 3 cases, and endovenous laser therapy in 3 cases. Additionally, remnant varicosities after first operations were treated by endovenous laser therapy in all cases. During the mean postoperative follow-up period of 60 months, complications included edema of the foot and petechia in 2 cases each, and were not severe. CONCLUSION: Operative treatments including high ligation and stripping, and endovenous laser therapy are very effective for the management of varicose vein in the pediatric population, with improvements in quality of life including relief of symptoms and management of the cosmetic aspect.

Clinical Experience of the Klippel-Trenaunay Syndrome

BACKGROUND: The Klippel-Trenaunay syndrome (KTS) is characterized by three clinical features, namely cutaneous capillary malformations, venous malformations, and soft tissue and/or bony hypertrophy of the extremities. The varied manifestations are attributed to the unpredictable clinical nature and prognosis of the syndrome. To elucidate the clinical characteristics of this disease, we reviewed a relatively large number of KTS patients who presented to our vascular anomalies center. METHODS: We conducted a retrospective study with 19 patients who were diagnosed with KTS and treated in our vascular anomalies clinic between 2003 and 2014, and examined their demographic characteristics, their clinical features, and the treatments administered. RESULTS: The sex distribution was balanced, with 9 (47%) males and 10 (53%) females. The mean follow-up period was 4.1 years (range, 7 months-9 years). Most of the patients received conservative treatments such as medication or physiotherapy. Compression therapies such as wearing of elastic garments/bandages were also administered, and surgical interventions were considered only when the patients became excessively symptomatic. Other treatments included laser therapy and sclerotherapy, and all the treatments were adjusted according to each case, tailored to the conditions of the individual patients. CONCLUSIONS: KTS is an extremely rare, multifactorial disorder that induces widely varied symptoms. Because of this unique feature, plastic surgeons, when not careful, tend to attach a one-sided importance to typical symptoms such as limb hypertrophy or capillary malformation and thus overlook other symptoms and clinical features. KTS can be suspected in all infants who show capillary malformations or limb hypertrophy and require a multi-disciplinary approach for comprehensive management.

Intraosseous Arteriovenous Malformation of the Sphenoid Bone Presenting with Orbital Symptoms Mimicking Cavernous Sinus Dural Arteriovenous Fistula: A Case Report

Intraosseous arteriovenous malformation (AVM) in the craniofacial region is rare. When it occurs, it is predominantly located in the mandible and maxilla. We encountered a 43-year-old woman with Klippel-Trenaunay syndrome affecting the right lower extremity who presented with a left orbital chemosis and proptosis mimicking the cavernous sinus dural arteriovenous fistula. Computed tomography angiography revealed an intraosseous AVM of the sphenoid bone. The patient's symptoms were completely relieved after embolization with Onyx. We report an extremely rare case of intraosseous AVM involving the sphenoid bone, associated with Klippel-Trenaunay syndrome.

Facomatosis pigmentovascularisasociada a síndrome de Klippel-Trenaunay y a alopecia triangular: reporte de caso / Pigmentovascularis phacomatosis associated to Klippel-Trenaunay syndrome and triangular alopecia: a case report

La facomatosis pigmentovascularis se caracteriza por la coexistencia de malformaciones vasculares cutáneas con nevus melanocíticos y hasta en un 50 % de los casos puede tener compromiso sistémico. El sistema de clasificación tradicional identificaba cinco categorías, numeradas del I al V de acuerdo a la presencia de cierto tipo de nevus, subdivididos en tipo a y b dependiendo de si existe o no compromiso sistémico. Más recientemente, Happle propone una nueva categorización basada en los hallazgos clínicos así: cesioflammea (mancha mongólica y nevus flammeus), spilorosea (nevus de Spilus y nevus telangiectásico) y cesiomarmorata (mancha mongólica y cutis marmorata telangiectásico congénita), siendo la primera la más común. Se presenta el caso de un paciente masculino de tres años de edad, quien desde el nacimiento presentaba una malformación vascular capilar tipo nevus flammeus extenso, mancha mongólica, melanosis escleral e iris mamilado, una malformación venosa congénita localizada en la región suprapúbica, además de alopecia triangular, a quien se le hizo el diagnóstico inicial de facomatosis pigmentovascularis tipo cesioflammea y posteriormente se asoció a síndrome de Klippel Trenaunay.

Phacomatosis pigmentovascularis is a disorder characterized by cutaneous vascular malformations associated with melanocytic nevi: up to 50 % of patients have systemic involvement. The traditional classification system identifies 5 categories numbered from I to V according to the presence of certain types of nevi, and it subdivides the categories into type a and b, depending on whether or not systemic involvement is present. More recently, Happle proposed a new classification based on clinical findings as follows: cesioflammea (Mongolian spot and nevus flammeus), spilorosea (telangiectatic nevus and nevus Spilus) and cesiomarmorata (Mongolian spot and congenital telangiectatic cutis marmorata), the first one being the most common one. We present a case of a 3 year old male patient who presented at birth with a capillary vascular malformation, an extensive nevus flammeus, a Mongolian spot, scleral melanosis and mammilated iris, a suprapubic congenital venous malformation and triangular alopecia; he was diagnosed with cesioflammea phacomatosis pigmentovascularis that was later associated with Klippel Trenaunay Syndrome.

Síndrome de Klippel-Trenaunay-Weber: associação do tratamento operatório à escleroterapia por espuma / Klippel-Trenaunay-Weber syndrome: association of operative treatment with foam sclerotherapy

A Síndrome de Klippel-Trenaunay-Weber representa a associação de hemangiomas planos, ectasias venosas e hipertrofia do segmento corpóreo afetado. Apresenta-se o caso de um paciente de 39 anos, sexo masculino, seguido desde 1993 no serviço da Disciplina de Cirurgia Vascular da Escola Paulista de Medicina (Unifesp), por quadro inicial da síndrome em membro inferior esquerdo. O paciente foi tratado apenas por elastocompressão e medidas gerais. Neste período, ele evoluiu com piora da estase venosa, da hipertrofia óssea e da hiperpigmentação de pele. Na ultrassonografia Doppler colorida venosa dos membros inferiores havia perviedade do sistema venoso profundo, hiperfluxo venoso, insuficiência segmentar de veia safena magna com sinais de tromboflebite e tributárias insuficientes. Indicou-se, para a melhora da estase venosa, ligadura da junção safeno-femoral esquerda e escleroterapia (polidocanol 3 por cento) retrógrada da mesma, com exérese das ectasias venosas. O paciente recebeu alta hospitalar no primeiro dia pós-operatório e atualmente está em acompanhamento ambulatorial com melhora significativa dos sintomas.

The Klippel-Trenaunay-Weber Syndrome is the association of hemangioma, venous ectasia, and hypertrophy of the affected body segment. We report the case of a 39-year-old male followed-up since 1993 due to onset of symptoms in the left lower limb. He was treated only with the use of elastic stockings and general measures. Over the years, he had worsening of venous stasis, of bone hypertrophy, and of skin hyperpigmentation. Color-coded Doppler ultrasonography of the lower limbs showed patency of the deep venous system, venous overflow, segmentar insufficiency of the greater saphenous vein with signs of thrombophlebitis, and insufficient tributary veins. In order to improve venous stasis, ligation of the left sapheno-femoral junction and retrograde foam sclerotherapy (polidocanol 3 percent) with resection of tributary veins were performed. The patient was discharged in the first postoperative day and has been followed as an outpatient, presenting significant improvement of the symptoms.

Klippel-Trenaunay syndrome associated with bladder hemangioma: a case report and literature analysis / 中华泌尿外科杂志

ObjectiveTo discuss the treatment of a rare case of Klippel-Trenaunay syndrome associated with bladder hemangioma and conduct a brief literature review. MethodsA 23-year-old female manifested episodes of painless hematuria for 1 month.A biopsy by cystoscopy diagnosed angiomatosis.The patient had a history of left lower limb hemangioma for 23 years,and underwent 3 surgical operations at 3 months old,3 years old,and 13 years old.The left leg was longer than the right leg.There was some soft tissue hypertrophy in the left lower extremity.Ultrasonography showed a bladder mass.Cystoscopy revealed a 3 cm x 5 cm sized hemangiomatous on the left lateral and anterior wall of the bladder. ResultsThe patient was diagnosed with bladder hemangioma and Klippel-Trenaunay syndrome.Partial cystectomy was performed.The pathological diagnosis was bladder intramuscular hemangioma. ConclusionKlippel-Trenaunay syndrome associated with bladder hemangioma can be treated by partial cystectomy.

Involvement of Splenic Hemangioma and Rectal Varices in a Patient with Klippel - Trenaunay Syndrome / 대한소화기학회지

Klippel - Trenaunay syndrome (KTS) is characterized by a cutaneous vascular nevus of the involved extremity, bone and soft tissue hypertrophy of the extremity and venous malformations. We present a case of KTS with splenic hemangiomas and rectal varices. A 29-year-old woman was referred for intermittent hematochezia for several years. She had history with a number of operations for cutaneous and soft tissue hamangiomas since the age of one year old and for increased circumference of her left thigh during the last few months. Abdominal CT revealed multiple hemangiomas in the spleen, fusiform aneurysmal dilatation of the deep veins and soft tissue hemangiomas. There was no evidence of hepatosplenomegaly or liver cirrhosis. Colonoscopy revealed hemangiomatous involvement in the rectum. There were rectal varices without evidence of active bleeding. Upon venography of the left leg, we also found infiltrative dilated superficial veins in the subcutaneous tissue and aneurysmal dilatation of the deep veins. The patient was finally diagnosed with KTS, and treated with oral iron supplementation only, which has been tolerable to date. Intervention or surgery is not required. When gastrointestinal varices or hemangiomatous mucosal changes are detected in a young patient without definite underlying cause, KTS should be considered.

Diagnóstico prenatal ecográfico del Síndrome Klippel-Trenaunay-Weber: a propósito de un caso / Prenatal sonographic diagnosis of Klippel-Trenaunay-Weber syndrome: a case report

El estudio del feto utilizando ultrasonido en tiempo real es uno de los avances tecnológicos más importantes de los últimos tiempos, permitiendo obtener información acerca de su integridad anatómica y funcional, así como establecer el diagnóstico de defectos congénitos en las etapas tempranas del embarazo. El Síndrome Klippel-Trenaunay-Weber fue originalmente reportado por Maurice Klippel y P. Trenaunay en 1900, el hallazgo clínico más frecuente es el angioma plano o nevus flammeus. Se presenta un caso de una gestante de 18 años, primigesta, con antecedente de salud previo, que acude a la consulta por presentar Hb AS. El estudio ecográfico realizado a las 22 semanas de gestación reveló marcada hipertrofia del miembro inferior izquierdo fetal asociado a hemangioma cavernoso gigante que afectaba pelvis, nalgas y genitales. Tales hallazgos guiaron al diagnóstico de Síndrome Klippel-Trenaunay-Weber. Esta entidad clínica es considerada una rareza, siendo su diagnóstico prenatal ecográfico poco conocido por lo que se presenta el caso.

The study of the fetus using the ultrasound in real time is one of the most important technological advances of recent days; which allow collecting information about anatomic and functional integrity as well as establishing the diagnosis of congenital malformations in early stages of pregnancy. Klippel-Trenaunay-Weber syndrome was first reported by Maurice Klippel and P. Trenaunay in 1900, the most frequent clinical finding is the flat angioma or flammeus nevus. An 18 years old primigravida having health records attended to the office presenting HbAS. The sonographic study carried out at 22 weeks of pregnancy revealed a marked hypertrophy of the lower fetal limb associated with giant cavernous angioma affecting the pelvis, buttocks and genitals. Such findings guided to the diagnosis of Klippel-Trenaunay-Weber syndrome. This is a rare clinical entity and its antenatal diagnosis is little- known, thus the case is presented.

Dominant inheritance and intra–familial variations in the association of Sturge–Weber and Klippel–Trenaunay–Weber syndromes.

This case report shows a genealogical study where a woman has limb hypertrophy and her son has an association of Sturge–Weber syndrome with Klippel–Trenaunay–Weber syndrome. The Sturge–Weber and Klippel–Trenaunay–Weber syndromes appear to be different manifestations of the same affliction. Familial aggregation exists and transmission may be almost imperceptible between generations. Identification of minor manifestations may prove to be a valuable contribution to genetic counseling of families and the prevention of new cases.
