Cobb syndrome effectively treated with trametinib.

Cobb syndrome is a rare neurocutaneous disease characterized by vascular anomalies involving the skin and spinal cord at the same metamere. The most common initial symptoms are neurological manifestations such as pain, monoparesis, headache, scoliosis, and motor damage. We present two patients with Cobb syndrome and severe disease burden harboring somatic mutations in KRAS.

Ethanol embolization of arteriovenous malformations in the buttock: ten-year experiences in diagnoses and treatment options.

Background: Clinically, arteriovenous malformations in the buttocks (bAVMs) are extremely rare. Our study aimed to evaluate the efficacy and safety of ethanol embolotherapy in managing bAVMs.

Results: A total of 32 patients with bAVMs (14 females and 18 males) from 2012 to 2021 were included in this study.

Overview of peripheral arteriovenous malformations: From diagnosis to treatment methods.

Based on the latest classification by the International Society for the Study of Vascular Anomalies in 2018, vascular malformations (VMs) can be categorized into simple, combined VMs of major named vessels, and VMs associated with other anomalies. Simple VMs include lymphatic, venous, capillary, and arteriovenous malformations (AVMs). AVMs represent disorders of direct arteriovenous shunts caused by the absence of a capillary bed between the involved arteries and veins.

Teaching NeuroImage: Clinical and Imaging Features of Cobb Syndrome.

A 17-year-old boy with typical neurodevelopment presented with 3 months of lower-limb weakness without a history of trauma. Physical examination, plain radiography and a T2-weighted MRI revealed a port-wine stain over the lumbar region, significant scoliosis below the cervical segment, and a multifocal flow void sign (steal phenomenon) from epidural space to dorso-lumbar spine, respectively (Figure 1). CT angiography identified an enhancing dorsal vascular mass with involvement of the spinal canal including destruction of the vertebral body determined to be extensive arteriovenous shunts on digital subtraction angiography (DSA) (Figure 2).

[Clinical analysis of interventional embolization for 9 cases with frontal arteriovenous malformation].

Purpose: To investigate the efficacy and safety of interventional embolization in the treatment of frontal arteriovenous malformation (AVM).

Methods: A retrospective study was used to analyze 9 patients with frontal AVM who were treated in Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine. The patients were treated with interventional embolization under the guidance of DSA.

Angiographic Types of Palpebral Arteriovenous Malformations and Relevant Therapeutic Options Based on Ethanol Embolization: A Multicenter Study.

Purpose: The present work aimed to determine the different angio-architectural types of palpebral arteriovenous malformations (pAVMs) and appropriate ethanol embolotherapy for each type.

Materials And Methods: This was a multi-center comparative effectiveness research retrospectively conducted from November 2012 to October 2021. A total of 70 patients with pAVMs were included, which was classified into cystic pAVMs (n=29) and diffuse pAVMs (n=41) based on the angio-architecture.

Eradication of the nidus in arteriovenous malformations with a dominant outflow vein in the lower extremities using coils and absolute ethanol.

Objective: In the present study, we summarize our experience in locating the nidus of arteriovenous malformations (AVMs) with a dominant outflow vein (DOV) in the lower extremities and eradicating the nidus with ethanol and coils.

Methods: Twelve patients with lower extremity AVMs who underwent ethanol embolization combined with DOV occlusion from January 2017 to May 2018 were enrolled in the present study. Selective angiography was used to locate the nidus of the AVMs, which was eradicated using ethanol and coils via the direct puncture pathway.

Comprehensive analysis of exosomal circRNA, lncRNA, and mRNA profiles to identify the potential RNAs involved in the pathogenesis of venous malformation.

Background: Venous malformation (VM) is a kind of congenital vascular anomaly with a high incidence of recurrence, detailed pathogenesis and standard treatment of VM still lack now. Increasing evidence showed exosomal RNA plays a pivotal role in various diseases. However, the underlying mechanism of VM based on the potential differentially exosomal RNAs remains unclear.

Ethanol Embolization of Chest Wall Arteriovenous Malformations: Four-Year Findings.

Objectives: To summarize the clinical characteristics and investigate the efficacy of ethanol embolotherapy in the treatment of chest well arteriovenous malformation (AVM). Treatment-associated complications were also explored.

Materials And Methods: Between March 2017 and August 2021, 32 consecutive patients (mean age, 23.

Surgical Resection Combined with Sclerotherapy Treating Maffucci Syndrome's Venous Malformation in Head and Neck Region.

Purpose: Here, we report our experience treating a patient with Maffucci syndrome and evaluate the outcomes resulting from surgical management combined with sclerotherapy in the treatment of head and neck venous malformations (VMs). A 19-years-old woman with multiple enchondromas and heterauxesis complained of masses in the oral cavity that had gradually increased in size and eventually affected her daily life. A tracheotomy was performed followed by traditional sclerotherapy to treat the oropharyngeal VMs.

Management of high-output cardiac failure caused by head and neck AVMs: Percutaneous suture-assisted ethanol and coil embolotherapy.

Purpose: The aim of this study was to describe the treatment technique, outcomes, and complications of Schobinger stage IV head and neck arteriovenous malformations (HNAVMs) with associated high-output cardiac failure (HOCF) using ethanol and coils with the percutaneous suture technique.

Methods: From January 2015 to December 2019, 19 patients who had HNAVMs with associated HOCF were treated first with a percutaneous suture of the remarkably dilated dominant drainage vein (RDDOV) and subsequent embolization with coils and ethanol. The percutaneous suture of RDDOV was preferred to be performed, followed by the deployment of coils and the injection of absolute ethanol transarterial approach, direct puncture approach, or both of them.

COL3A1: Potential prognostic predictor for head and neck cancer based on immune-microenvironment alternative splicing.

We aimed to identify a novel prognostic biomarker for head and neck squamous cell carcinoma (HNSCC) based on tumor immunology-related alternative splicing (AS). Data for 502 HNSCC and 44 normal samples were obtained from the TCGA database and used to establish an AS-related risk model through univariate, least absolute shrinkage, and selection operator Cox regression analyses. Fresh HNSCC and normal oral tissues were surgically obtained from 44 HNSCC patients.

Embolization for Arteriovenous Malformations in the Maxilla With Coils and Ethanol.

Methods: In this retrospective case series, we enrolled a sample of patients with maxillary AVMs treated with embolization using coils with or without ethanol between June 2017 and July 2019.

Novel classification for simple peripheral arteriovenous malformations based on anatomic localization: Prevalence data from the tertiary referral center in China.

Background: In 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.

Results: Between 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.
