Arteriovenous malformation (AVM) is a vascular lesion with a direct communication between an artery and a vein without a capillary system. AVM primarily occurs in the intracranial area, but can also occur in the extracranial area. If there is a tender mass with pulsation or recurrent bleeding in the auricle, AVM should be considered even though it rarely occurs in the auricle. AVM in the ear should be managed carefully because the skin is thin in the ear, the cartilage could be involved, and progressive growth or inappropriate management could cause bleeding, infection, and cosmetic problems such as deformity. I present a case of a 59-year-old woman with AVM in the auricle.

Arteriovenous malformation (AVM) is a common form of vascular malformation, an abnormal direct communication between an artery and a vein without passing through the capillaries. AVM may just present as hematuria without plain or other symptoms. The article presents a case of a 52-year-old male with gross hematuria diagnosed as AVM of internal pudendal artery, which was successfully managed with superselective arterial embolization using temporary embolization materials.

We describe a 24-year-old woman who presented with twice previously unverified subarachnoid hemorrhages from the conus medullaris spinal arteriovenous malformation with Parkes-Weber-syndrome. Spinal MRI examination is considered to be necessary for the diagnosis of Klippel-Trenaunay-Weber syndrome. For diagnosis of the spinal cord arteriovenous malformation, it is indispensable to search carefully for the presence of accompanying lesions. Transarterial glue embolization is effective for the management of the spinal vascular lesion.

Etiological Spectrum

OBJECTIVEUnderstanding the etiological spectrum of nontraumatic pediatric intracerebral hemorrhage (pICH) is key to the diagnostic workup and care pathway. The authors aimed to evaluate the etiological spectrum of diseases underlying pICH.METHODSChildren treated at the authors’ institution for a pICH were included in an inception cohort initiated in 2008 and retrospectively inclusive to 2000, which was analyzed in October 2019. They then conducted a systematic review of relevant articles in PubMed published between 1990 and 2019, identifying cohorts with pICH. Identified populations and patients from the authors’ cohort were pooled in a multicategory meta-analysis.RESULTSA total of 243 children with pICH were analyzed in the cohort study. The final primary diagnosis was an intracranial vascular lesion in 190 patients (78.2%), a complication of a cardiac disease in 17 (7.0%), and a coagulation disorder in 14 (5.8%). Hematological and cardiological etiologies were disproportionately more frequent in children younger than 2 years (p < 0.001). The systematic review identified 1309 children in 23 relevant records pooled in the meta-analysis. Overall, there was significant heterogeneity. The dominant etiology was vascular lesion, with an aggregate prevalence of 0.59 (95% CI 0.45–0.64; p < 0.001, Q = 302.8, I2 = 92%). In 18 studies reporting a detailed etiological spectrum, arteriovenous malformation was the dominant etiology (68.3% [95% CI 64.2%–70.9%] of all vascular causes), followed by cavernoma (15.7% [95% CI 13.0%–18.2%]).CONCLUSIONSThe most frequent etiology of pICH is brain arteriovenous malformation. The probability of an underlying vascular etiology increases with age, and, conversely, hematological and cardiac causes are dominant causes in children younger than 2 years.

Abstract Fifteen cerebellar vermian arteriovenous malformations were surgically treated over a 7-year period. Intracranial hemorrhage was the presenting symptom in 73% of the cases and recurrent bleeding episodes occurred in 60%. Computed tomographic scans demonstrated the site of the malformation in 80% and documented the presence of intracerebral bleeding in all posthemorrhage patients. Angiography revealed two consistent patterns of arterial supply depending on the involvement by the malformation of the superior inferior cerebellar vermis. All lesions were surgically removed via a midline suboccipital posterior fossa microsurgical approach. Intraventricular extension of arteriovenous malformation was common, often in association with the choroid plexus of the 4th ventricle. Immediate postoperative angiography was used to document arteriovenous malformation removal. Three instances of unsuspected residual malformation were documented and required reexploration. The total operative mortality was 7%, and the neurological morbidity was 21%.

Abstract OBJECTIVE AND IMPORTANCE: Intrinsic arteriovenous malformation (AVM) of the trigeminal nerve is extremely uncommon and may be associated with trigeminal neuralgia. CLINICAL PRESENTATION: A 55-year-old man experienced severe lightning pain in the second and third divisions of the left trigeminal nerve territory. Vertebral angiography demonstrated an AVM fed by the superior cerebellar artery. Magnetic resonance imaging with three-dimensional spoiled gradient recalled acquisition at steady state revealed an AVM intrinsic to the left trigeminal nerve and a small arterial loop causing compression at the root entry zone of the trigeminal nerve. INTERVENTION: Intraoperative inspection revealed an indentation of the root entry zone caused by a small arterial loop but not by the AVM. The offending artery was displaced to decompress the root entry zone using a prosthesis without resection of the AVM. The patient was relieved of the neuralgia immediately after surgery without further neurological deficit. He has been free of trigeminal neuralgia during a follow-up period of 2 years and is scheduled to undergo stereotactic radiosurgery for the treatment of the AVM. CONCLUSION: Intrinsic AVM of the trigeminal nerve may cause trigeminal neuralgia. However, as in the present case, a coexistent vascular lesion rather than the intrinsic AVM could be a cause of the neuralgia.

  THE LATE ONSET RE-BLEEDING AFTER 14 YEARS OF RUPTURE CEREBELLAR AVMABSTRACTThe arteriovenous malformation (AVM), a form of abnormality in brain vascularization, in the cerebellum is a rare disorder. The risk of recurrent bleeding after initial episode at five years is very low about 3,67%. We reported a case of 25 years-old man with history of recurrent bleeding after 14 years with hydrocephalus as complication. The brain CT scan showed a bleeding in the cerebellar vermis  with non-communicant hydrocephalus. The Digital Subtraction Angiography (DSA) showed a moderate left cerebellar AVM with high-flow plexiform nidus, left superior cerebellar artery as primary feeding artery with supplementary supply of the vein draining from the superior cerebellar artery to superior petrosal vein leading to the superior petrosal vein toward the contralateral transverse sinus and left sigmoid sinus. Embolization for infratentorial posterior fossa AVM bleeding needs to be considered even though previous bleeding occurs over 5 years to prevent re-bleeding.Keywords: Arteriovenous malformation, embolization, feeding artery, nidusABSTRAKKelainan pembuluh darah malformasi arteriovena (MAV) pada serebelum merupakan kelainan vaskular yang jarang terjadi. Risiko pendarahan berulang setelah tahun kelima adalah rendah sekitar 3,67%. Dilaporkan suatu kasus laki-laki, 25 tahun, dengan riwayat pendarahan serebri berulang setelah 14 tahun dengan komplikasi hidrosefalus. CT scan kepala menunjukkan adanya pendarahan pada bagian vermis dengan hidrosefalus non-komunikan. Pemeriksaan DSA (digital subtraction angiography) menunjukkan adanya MAV fosa posterior di serebelum kiri ukuran sedang dengan nidus pleksiformis high flow dan feeder utama arteri serebelaris superior kiri ke vena petrosal superior menuju ke sinus transversus kontralateral dan sinus sigmoid kiri. Tata laksana embolisasi pada MAV infratentorial fosa posterior yang mengalami pendarahan perlu dipertimbangkan walaupun pendarahan sebelumnya terjadi lebih dari 5 tahun untuk mencegah pendarahan kembali.Kata kunci: Embolisasi, feeding arteri, malformasi arteriovena, nidus

Spontaneous rupture of an intercostal artery is exceptionally rare. It can be complicated by haemothorax, haematoma and/or retroperitoneal haemorrhage, which contributes to its morbidity and mortality. The authors report a case of a 76-year-old patient who was referred to the emergency department for pain associated with the appearance of a mass with progressive growth for 2 days in the right subscapular region. The patient had no previous history of trauma, ecchymosis or noticeable skin changes. History included the use of acetylsalicylic acid and a history of heart failure, as well as haemodialysis due to stage 5 chronic renal disease. CT scan showed an active haemorrhage from an artery in the fifth intercostal space. Embolisation was performed with microspheres and microcoils. No complications or recurrent bleeding was observed. Spontaneous rupture of an intercostal artery is rare, but it is an emergency requiring immediate diagnosis and intervention.

Hemangioma is a congenital vascular soft tissue tumor, defined as a vascular lesion present in the newborn, with a progressive developmental pattern related to age. It has a progressive and regressive periodic growth mode, in comparison with arteriovenous malformation (AVM). Although there are many treatment approaches for curing this lesion such as; surgery, cryotherapy, sclerosant agents, laser therapy has more advantages in comparison to the other methods. Such as, hemostasis and clean operating field, decreased amount of pain and edema. There are many types of lasers manufactured that could be used for therapeutic purposes. This article focuses on different types of laser applications in the treatment of these lesions.
