INTRODUCTION: Warfarin therapy is recommended in children with giant coronary artery aneurysms (GCAAs) after Kawasaki disease (KD). Large individual variability makes it difficult to predict the warfarin dose. Polymorphisms in the vitamin K expoxide reductase 1 (VKORC1) and cytochrome P4502C9 (CYP2C9) genes have been reported to influence the warfarin dose. We investigated the effects of the VKORC1 and CYP2C9 genotypes on the warfarin dose in pediatric patients with giant CAAs after KD...

BACKGROUND: Duane syndrome is a congenital eye movement disorder characterized by congenital malformation of the abducens nucleus. Thrombogenic conditions during development may lead to vascular anomalies in Duane syndrome, however, the presence of a giant aneurysm in this patient population is a rarely documented phenomenon. CASE DESCRIPTION: We reported a case of a large cerebral aneurysm in a pediatric patient with Duane syndrome, and performed a review of the literatures to identify other potential cases and associations...

Kawasaki disease (KD), which is the leading cause of pediatric heart disease, is characterized by coronary vasculitis and subsequent aneurysm formation. Although intravenous immunoglobulin therapy is effective for reducing aneurysm formation, a certain number of patients are resistant to this therapy. Because interleukin-10 (IL-10) was identified as a negative regulator of cardiac inflammation in a murine model of KD induced by Candida albicans water-soluble fraction (CAWS), we investigated the effect of IL-10 supplementation in CAWS-induced vasculitis...

Mixed connective tissue disease (MCTD) syndrome in children may lead to large aortic aneurysms, which in turn pose a difficult surgical problem. Valve-sparing root replacement is not always a viable option as the disease process invariably affects the aortic valve leaflets. Among pediatric patients, the Ross procedure is contraindicated on account of weakness of the pulmonary root, while Bentall surgery is the 'gold standard' treatment of aortic aneurysm, with reproducible and excellent long-term results. The case is presented of a three-year-old girl with a large thoracic aortic aneurysm in whom Bentall's surgery was performed, with a good result...

INTRODUCTION: Polyarteritis nodosa is a necrotizing vasculitis that mainly affects small and medium-sized arteries in skin and internal organs. Neurological involvement is reported in around 25% of cases: ischemic stroke is relatively common, but haemorrhagic lesions are extremely rare. Subarachnoid haemorrhage in polyarteritis nodosa is an uncommon expression of this disease, mostly associated with aneurism rupture. To the best of the authors' knowledge, there is just one published case in pediatric age with polyarteritis nodosa and subarachnoid haemorrhage with no underlying aneurismal disease...

Treatment of aneurysmal lesions in the context of coarctation of the aorta (CoA) is a challenging task and these lesions are rare in children. An 11-year-old boy was incidentally diagnosed with native CoA and concomitant complex aneurysmal lesions during medical check-up for arterial hypertension. Pre-catheterization imaging was performed with computed tomography (CT), which showed a mild CoA and two native aneurysms that were juxtaposed to the origin of the left subclavian artery. For planning and guidance of the catheter procedure, image fusion software was used with an overlay from pre-registered three-dimensional reconstruction images on live fluoroscopy...

INTRODUCTION: Intracranial aneurysms are very rare in children. Although subarachnoidal hemorrhage (SAH) is by far the most common presentation of aneurysms in the majority of the pediatric case series, it is not rare for an unruptured aneurysm to present with a mass effect. Acute hydrocephalus is a common finding following aneurysmal SAH. However, this malady may develop even in the absence of SAH but secondary to direct obstruction by a giant aneurysm. This situation is extremely rare in children, with only a few known case reports in the literature...

INTRODUCTION: Contrast-enhanced ultrasound (CEUS) using intravascular microbubbles has potential to revolutionize point-of-care ultrasonography by expanding the use of ultrasonography into clinical scenarios previously reserved for computed tomography (CT), magnetic resonance imaging, or angiography. METHODS: We performed a literature search and report clinical experience to provide an introduction to CEUS and describe its current applications for point-of-care indications...

This report presents an unusual case of traumatic iliofemoral vessel transection in a 3-year-old patient successfully reconstructed using a cryopreserved greater saphenous conduit. Five years after injury, the patient continues to do well with normal ambulation. An arterial duplex demonstrated graft patency free of aneurysmal dilatation. These encouraging results suggest that the natural history of cryopreserved conduits may differ in the pediatric population and cryopreserved conduits could be used for complex vascular reconstructions...

Vein of Galen aneurysmal malformations (VGAMs) are rare vascular malformations occurring commonly in the pediatric age group. They comprise only 1% of all intracranial vascular malformations, but in pediatric population, they represent 30% of all intracranial vascular malformations. They are of two types-mural and choroidal. Choroidal type of VGAM is more primitive and most severe form of disease. It usually causes high cardiac output failure in newborn period because of multiple high flow fistulas. Adult presentation of choroidal type VGAM is very rare, and only few cases have been reported in literature so far...

BACKGROUND: Hand ischemia following trauma in children is rare and the natural history after upper extremity arterial bypass in children is unknown. We hypothesize children with brachial artery repair are at long term risk of developing aneurysmal degeneration or Thrombosis thus necessitating annual duplex ultrasonography and physical examination. STUDY DESIGN: A retrospective review of children who had brachial artery repair (bypass or vein patch) for hand ischemia secondary to trauma at a level I trauma pediatric hospital was performed...

Radiotherapy is a useful modality for the treatment of brain tumors, but may induce brain degeneration, tumor formation, and vasculopathy in the irradiated field. We describe a rare case of a pediatric patient who presented multiple different types of vascular events consecutively in the irradiated field including lacunar stroke because of occlusion of perforating artery, intraventricular hemorrhage from cavernoma, and subarachnoid hemorrhage because of the rupture of fusiform aneurysm, 6 years after radiotherapy against pilocytic astrocytoma...

BACKGROUND AND PURPOSE: Arteriopathy is common in childhood arterial ischemic stroke (AIS) and predicts stroke recurrence. Currently available vascular imaging techniques mainly image the arterial lumen rather than the vessel wall and have a limited ability to differentiate among common arteriopathies. We aimed to investigate the value of a magnetic resonance imaging-based technique, namely noninvasive arterial wall imaging (AWI), for distinguishing among arteriopathy subtypes in a consecutive cohort of children presenting with AIS...

Pilocytic astrocytomas (PAs) are benign glial tumors and one of the most common childhood posterior fossa tumors. Spontaneous intratumoral hemorrhage in PAs occurs occasionally, in about 8-20% of cases. Cerebellar hemorrhages in pediatric population are rare and mainly due to head injuries, rupture of vascular malformations, infections, or hematological diseases. We have investigated the still controversial and unclear pathophysiology underlying intratumoral hemorrhage in PAs. Bleeding in low-grade tumors might be related to structural abnormalities and specific angio-architecture of tumor vessels, such as degenerative mural hyalinization, "glomeruloid" endothelial proliferation, presence of encased micro-aneurysms, and glioma-induced neoangiogenesis...

OBJECTIVE: Autograft dilatation is the main long-term complication following the Ross procedure using the freestanding root replacement technique. We reviewed our 25-year experience with the Ross procedure with a special emphasis on valve-sparing reoperations. METHODS: From 1991 to 2016, 153 patients (29.6 ± 16.6 years; 29.4% pediatric) underwent a Ross operation at our institution with implantation of the autograft as freestanding root replacement. The follow-up is 98...

Marfan syndrome is a well-described autosomal dominant connective tissue disorder with a constellation of anatomic characteristics including aortic degeneration as a result of the spontaneous mutation of the fibrillin gene, FBN1 . Whereas life-threatening dissection and ascending aneurysmal rupture have been thoroughly documented in the literature, aneurysms of the abdominal aorta and those present in the pediatric population have only rarely been reported. In this case report, we describe presentation, successful open surgical repair, and recovery of a pediatric Marfan syndrome patient with a ruptured abdominal aortic aneurysm...

Purpose: Adjuvant coils may offer advantages in flow control during glue embolization of high flow vein of Galen aneurysmal malformation (VGAM) patients but involves specific issues such as feasibility, durability and coil mass effect. The purpose of this study is to assess the outcome of adjuvant coils in addition to transarterial glue embolization for treatment of these patients. Materials and Methods: Five pediatric VGAM patients (age range; 11 weeks to 2 yrs 2 mos) with high flow fistulous angioarchitecture were treated with adjuvant coils 1) in the distal feeding artery and/or 2) in the vein of Galen followed by glue embolization of the shunt...
