“…However, due to the operative and invasive nature of angiography, AVM classifications mentioned above only focused on the angiographic results, imposed restrictions on the overall judgment of AVM (both primary lesion and surrounding tissue or structure). In light of the still poor understanding of AVM, misdiagnoses were widely reported ( 33 – 35 ). Thus, the correct pre-operation diagnosis of AVM not only has a guiding effect on therapeutic strategies but determines the prognosis of the patient to a large extent.…”

BackgroundIn absence of the large-sample study of simple peripheral arteriovenous malfomations (pAVM), we aimed to perform the epidemiological analysis of over 1,000 simple pAVM patients from our center in the past 5 years, and establish a novel classification based on the anatomical localization of the primary lesion.ResultsBetween March 27, 2016, and March 31, 2021, Chinese patients who were diagnosed with simple pAVM were taken into account. Those who suffered from simple arteriovenous malformations of the central nervous system (cnsAVM), combined types of AVM, and syndromes, such as CLOVES syndrome, etc. were all excluded from this study. A total of 1,070 simple pAVM patients were screened out. All of the simple pAVM patients were diagnosed by clinical manifestations and imaging examinations. Demographic data were obtained from the National Bureau of Statistics of China. The 5-year prevalence of simple pAVM was about (2.15–6.60) /1,000,000 population. The male-female ratio was approximately 1.22:1. The pAVM inpatients that were included in the age group of 21~30 years old had the highest constituent ratio (P = 0.01). The classification included four groups: Type I (primarily occurring in soft tissue); Type II (primarily occurring in bone); Type III (primarily occurring in the viscus) and Type IV (simple pAVM coexisting with CNS lesions). There were two subtypes of Type I: the A subtype (involving one major anatomical region) and the B subtype (involving two or more major anatomical regions); two subtypes of Type II: the A subtype (the cortex was intact) and the B subtype (the lesion had broken through the cortex). Generally, 657 patients were classified as Type IA (61.4%), 232 patients were Type IB (21.7%), 82 patients were Type IIA (7.7%) and 79 were categorized as Type IIB (7.4%); the number of patients who had Type III and Type IV pAVM were 9 (0.8%) and 11 (1.0%), respectively. The clinical manifestations and diagnostic standards for each type were also systematically summarized.ConclusionsPrevalence data for simple pAVM were analyzed, and a novel classification was proposed based on the anatomy of the lesions. The present work was expected to facilitate the diagnosis of simple pAVM in clinical works.

Cirsoid aneurysms (CAs) of the scalp are rare arteriovenous malformations presenting as nodular lesions of the scalp. Depending on the size and intracranial extension, they can vary from asymptomatic to potentially lethal from secondary hemorrhage. Being vascular clinically misdiagnosed cases may lead to a devastating outcome from any kind of diagnostic surgical intervention. Here, we report a case of a 45-year-old woman who presented with multiple papulonodular lesions on the scalp, diagnosed as CA.

“…La angiografía con sustracción digital es el gold standard para el diagnóstico de la lesión 6 . Sin embargo, la angiotomografía aporta datos útiles en el diagnóstico y tratamiento 7 . Dependiendo del origen de las arterias nutricias, las malformaciones del cuero cabelludo se clasifican en dos tipos: I, malformaciones vasculares primarias, y II, dilataciones venosas secundarias del cuero cabelludo 8 .…”

Las malformaciones arteriovenosas congénitas del cuero cabelludo representan el 8.1% de todas las malformaciones arteriovenosas, y son más frecuentes en adultos jóvenes. El objetivo de este trabajo es la presentación del caso de un recién nacido de sexo masculino, de 1 día de vida extrauterina y portador de una malformación arteriovenosa del cuero cabelludo, de alto flujo, localizada en la región parietooccipital izquierda, de difícil manejo y que culminó con el fallecimiento del paciente. No se cuentan con reportes similares en la literatura, por lo que se considera un caso clínico interesante.
