INTRODUCTION: We present an interesting case of a 55 year-old male with a large left chest mass after significant cutaneous bleeding. CT angiogram of the chest revealed arteriovenous malformation with blood supply from subbranches of the left subclavian artery, left internal mammary artery and left external carotid artery. Measuring 5.0x14.0x10.8cm, the mass extended superior to the clavicle and inferior to the third rib with medial and lateral borders at the level of the clavicular head and coracoid, respectively...

Most of the vascular lesions on head and neck soft tissue are congenital, but a rare cause can be trauma. A 23-year-old man came to our clinic with a wide pulsatile tortuous mass in the left temporofrontal area. That mass was appeared since 10 years ago. Ten years before his coming to our clinic, he had a blunt trauma in that area. After that, a small wound appeared there and healed gradually. In clinical examination, mass was large and pulsatile, and a fine murmur was detected from it. In paraclinical examination, computed tomography scan with intravenous contrast and sonography revealed a vascular mass with arteriovenous (AV) fistula in soft tissue only in that area...

OBJECTIVES: Vascular anomalies are included in the 30 000 rare diseases worldwide affecting less than 5/10 000 people. Depending on their morphology and biological properties, they can cause varied disorders with organ involvement. Almost 60% of vascular anomalies have a predilection for the head and neck region in children. Clinical and scientific effort to establish interdisciplinary management concepts for vascular anomalies is increasing worldwide. METHODS: Especially in the head and neck region, clinical impairment and organ dysfunction is associated with cosmetic issues that may represent a physical and psychological issue for the patient...

European adapids, especially Adapis parisiensis, have been extensively studied over the past two centuries, essentially for taxonomic and phylogenetic purposes. Analyses of dental, cranial, and postcranial morphology have led to various hypotheses about the diet, locomotion, and lifestyle of this fossil primate species. As the morphology of Adapis parisiensis is not directly comparable to any extant species, some interpretations are still debated. The inner ear is crucial to several functional parameters, such as auditory acuity, balance, agility, orientation, and head motion speed during locomotion...

BACKGROUND: Arteriovenous malformation (AVM) of the head and neck regions show low incidence; hence, studies regarding the causative factors of onset, diagnostic criteria, clinical aspects, treatment methods, and outcomes remain lacking. OBJECTIVE: To share the diagnostic and treatment experiences at the center and to understand the treatments' effect through a retrospective analysis of cases in the past 15 years. MATERIALS AND METHODS: The authors included 60 patients with AVM in the head and neck area between January 1999 and September 2014 to investigate diagnostic methods, distributions and locations of lesions, clinical stage, and treatment methods by retrospective evaluation...

Intraosseous Arteriovenous Malformations (AVMs) in the head and neck region are very rare and potentially life threatening entities due to massive hemorrhage. These are the results of an embryonic abnormality of the vascular system. Depending on the blood flow and clinical presentations they are of different types like slow flow and high flow AVM. Here we present a case of high flow AVM involving mandible with a chief complain of gingival bleeding in a four year old girl child.

PURPOSE: Multi-staged large AVM (>10 cm3 or diameter > 3 cm) Gammaknife radiosurgery requires setting up the patient based on a pre-treatment plan over several fractions. Residual rotational errors cannot be compensated by translational repositioning of the patient and may adversely impact the dose distribution on the total AVM target. This study evaluates the effect of residual rotational setup error. METHODS: The total AVM target was contoured and split into several small sub-targets...

Arteriovenous malformation (AVM) of the head and neck is a rare and potentially life threatening entity due to massive haemorrhage. There are several indications for treatment, including age of the patient and location, extent and type of vascular malformation. Endovascular therapy can effectively cure most lesions with limited tissue involvement. Surgery can be used in selected cases in combination with embolization. Here we report the case of a young woman affected by a massive AVM on the left side of the mandible and submandibular region, and also review the literature on AVM with special attention to treatment strategies...

Capillary malformation-arteriovenous malformation (CM-AVM; MIM 60354) is an autosomal dominant disorder characterized by multifocal cutaneous capillary malformations, often in association with fast-flow vascular lesions, which may be cutaneous, subcutaneous, intramuscular, intraosseus, or cerebral arteriovenous malformations or arteriovenous fistulas. CM-AVM results from heterozygous mutations in the RASA1 gene. Capillary malformations of the skin are common, and clinical examination alone may not be able to definitively diagnose-or exclude- CM-AVM...

AIM: To present the long-term angiographic and subjective results of patients with head and neck arteriovenous malformations (HNAVMs) after endovascular treatment. METHODS: We retrospectively analyzed the medical files of 14 patients with HNAVM who were treated between 2000 and 2014. The treatment of choice was a transarterial superselective microcatheter-based approach followed by embolization using liquid embolic agents. The patients were asked to answer a quality of life questionnaire about the following symptoms before and after treatment: pain, functional impairment, cosmetic deformity, impairment in daily life, and bleeding...

Dosimetric benchmarking at four hospitals was performed to investigate incident entrance dose and dose rate on a phantom, and entrance detector dose and dose rate for protocols that are used in routine clinical practice for complex neuroradiological treatment of arteriovenous malformations (AVMs). Measurements were performed with a head phantom that simulates the attenuation and scattering of the human head for the lateral and posteroanterior (PA) views. For fluoroscopy, the measured incident entrance dose rate and entrance detector dose rate were in the range of 44-172 and 0...

Arteriovenous malformation (AVM) of the pancreas is uncommon in the gastrointestinal tract. We present a case of AVM of the pancreatic head in a 59-year-old male. He was admitted to a hospital with hematemesis and tarry stool and referred to our hospital in March 2014 on the diagnosis of pancreatic artery pseudoaneurysm. A computed tomography scan showed the presence of irregular dilated and/or stenotic vessels with meandering in the pancreatic head. Magnetic resonance imaging showed strong enhancement of the conglomeration in the pancreatic head...

Craniofacial arteriovenous malformation (AVM), although very rare, has been a very difficult problem to treat especially when it is large and involves important structures. Surgical resection often results in unacceptable complications but still not curative. At our institution, treatment by combined intralesional neodymium-doped yttrium aluminium garnet laser and intratumoral ligation has been successful in venous malformation. This minimally invasive technique was then applied to more challenging AVM on the head and neck...

Sixty percent of vascular anomalies in children are found in the head and neck. These lesions can present throughout antenatal, perinatal and childhood development. They broadly fall into two categories: vascular tumours and vascular malformations. Their clinical and, often, psychological impact is determined by both pathological type and location: many lesions follow an uncomplicated natural course and other more complex, extensive or progressive lesions can present a threat to life from mass effect, haemorrhage or large volume arteriovenous shunting...

The treatment of brain arteriovenous malformations (AVMs) can be performed as a minimally invasive X-ray-guided procedure using a microcatheter for navigation to reach the target site. The performance of the interventional vascular surgery devices used for AVM was compared in four hospitals. The relation between image quality and the entrance surface air kerma (ESAK) was assessed for the default protocols for digital subtraction angiography (DSA) and fluoroscopy. A custom phantom, built with PMMA and aluminium plates was used to mimic the attenuation properties of the patient head...
