“…Moreover, AVMs should be differentiated from arteriovenous fistulas, which are characterized by a single communication between an artery and a vein. In contrast, AVMs have multiple communications between arterial and venous system [5]. In our case, a true AVM containing large nidus of dysplastic vessels was revealed.…”

“…Retroperitoneal AVMs should be differentiated from a variety of underlying conditions causing congestive heart failure. Sonography, magnetic resonance imaging (MRI) and DSA represent the cornerstone for morphological characterization of AVMs and facilitate their differentiation from other vascular anomalies [5]. A case of arteriovenous fistula arising from the descending aorta and draining into superior vena cava and the azygos vein was described in a 14-month-old girl [6].…”

Retroperitoneal Arteriovenous Malformation: A Rare Cause of Pulmonary Hypertension in a Premature Infant

et al. 2015

Retroperitoneal arteriovenous malformations (AVMs) are rare lesions consisting of dysplastic vessels, which may produce diverse clinical features. We report a case of premature neonate born on the 29th week of gestation, who presented with heart failure, generalized edema, respiratory dyspnea and metabolic acidosis. Digital subtraction angiography revealed a large AVM located adjacent to the aorta and the inferior vena cava. Lumbar arteries supplying the AVM were occluded by coils. The AVM was partially embolized using N-butyl cyanoacrylate. Despite apparently successful embolization procedure, heart failure and respiratory distress progressed. The newborn died on her fourth day of life. We report the first case describing AVM embolization in a very low birth weight preterm infant.

“…De bons résultats ont été rapportés par l'utilisation d'acide acétique [25] et d'un agent sclérosant alcoolique à base d'extrait de maïs et de traceur radio-opaque commercialisé sous le nom d'Éthibloc® (Laboratoire Ethicon, France). En effet, il a été noté 60 % à 80 % de succès sur des ML macrokystiques [4,27] mais des ulcérations cutanées avec extériorisation de fragments de produit ont été rapportées lors de son usage par injection percutanée en raison de sa composition alcoolique et de la quasiabsence de résorption [18]. La colle biologique peut également être utilisée.…”

“…Au niveau de la cavité orale, la face dorsale de langue est la plus souvent concernée, suivie de la face interne de la joue et de la fibromuqueuse palatine [9,11]. Trois théories existent actuellement pour expliquer l'origine du lymphangiome congé-nital [4]. Il se formerait soit par un défaut de connexion entre les sacs lymphatiques avec les vaisseaux lymphatiques et/ou le système veineux, soit par une malformation issue de cellules lymphatiques normales qui se développent indépendamment du reste du système lymphatique, soit par un processus néo-plasique, expliquant alors son comportement parfois localement agressif et récidivant.…”

Résumé -Introduction : Les malformations lymphatiques (ML) sont congénitales et non régressives. Elles résul-tent d'une anomalie de la morphogenèse embryologique vasculaire et sont détectées dans 80 % des cas avant l'âge de 2 ans, exceptionnellement à l'âge adulte. Asymptomatiques, elles sont le plus souvent diagnostiquées suite à une gêne fonctionnelle. Bien que d'aspects cliniques très hétérogènes, elles se regroupent en deux formes cliniques à distinguer, macrokystiques et microkystiques, dont les traitements et les pronostics diffèrent. L'aspect clinique de la lésion et la symptomatologie sont essentiels pour l'établissement du diagnostic mais aussi pour la décision thérapeutique. Bien qu'une surveillance clinique régulière soit souvent suffisante, une intervention thérapeutique est parfois nécessaire. Observations cliniques : Quatre cas de ML orales avec des aspects cliniques très hétéro-gènes sont présentés. L'un est situé au niveau de l'espace masticateur et de la fosse infratemporale avec une expression muqueuse à la commissure intermaxillaire, deux au niveau des muqueuses jugales et labiales, le quatrième au niveau de la langue. Discussion : Pour trois d'entre eux, le diagnostic a été réalisé à l'âge adulte et ceuxci ne présentaient aucun antécédent de ML. Deux ont été traités par laser, un par chirurgie, le dernier a bénéficié d'une surveillance clinique régulière. Conclusion : Ces quatre cas cliniques sont particulièrement représentatifs de l'hétérogénéité clinique buccale et thérapeutique de ces malformations.Abstract -Oral lymphatic malformations, case reports and review of the literature. Introduction: Lymphatic malformations (LMs) are congenital and non-regressive lesions. These lesions are due to embryological vascular morphogenesis abnormality. Most of them (80 %) are detected before 2 years old, and thus they are rarely found in adults. They are asymptomatic, so their diagnosis is often linked to functional discomfort. There are two clinical aspects with different prognoses: macrocystic and microcystic. Clinical aspects and symptomatology are essential for positive diagnosis and therapeutic decisions. For most cases, simple clinical observation is advised. However, in other cases associated with aesthetic or functional discomfort, therapeutic intervention is recommended, most of the time with sclerotherapy or surgery. Clinical observation: We present four patients with different types of lymphatic malformation: one is on the intermaxillary commissure, the second is on the cheek mucosa, the third is on the lip and the fourth is on the tongue. Discussion: For three of them, the diagnosis was established in adulthood with no past history of LMs. Two patients were treated by laser, one with surgery and for the last one, clinical follow-up was established. Conclusion: These four case reports are representative oral illustrations of the clinical aspects and therapeutic heterogeneity of this pathology.

Targeted narrowband intense pulsed light on cutaneous vasculature

et al. 2015

Background and Objectives Laser based therapies are the standard treatment protocol for port wine stain in the United States, but complete removal is infrequently achieved. Intense pulsed light (IPL) offers a broadband light spectrum approach as a viable treatment alternative. Previous studies suggest that IPL can be more effective in treatment of port wine stain by utilizing multiple wavelengths to selectively target different peaks in oxy- and deoxy-hemoglobin. Our study objectives were to (i) determine a characteristic radiant exposure able to achieve persistent vascular shutdown with narrowband IPL irradiation, (ii) determine the degree to which narrowband IPL irradiation can achieve persistent vascular shutdown, and (iii) compare the effectiveness of narrowband IPL radiation to single wavelength pulsed dye laser (PDL) irradiation in achieving persistent vascular shutdown. Study Design/Materials and Methods We utlized either single pulse or double, stacked pulses in narrowband IPL experiments, with the IPL operating over a 500–600 nm wavelength range on the rodent dorsal window chamber model. We compared the results from our narrowband IPL experiments to acquired PDL data from a previous study and determined that narrowband IPL treatments can also produce persistent vascular shutdown. We ran Monte Carlo simulations to investigate the relationship between absorbed energy, wavelength, and penetration depth. Results For single and double pulse narrowband IPL irradiation we observed (i) little to no change in blood flow, resulting in no persistent vascular shutdown, (ii) marked acute disruption in blood flow and vascular structure, followed by partial to full recovery of blood flow, also resulting in no persistent vascular shutdown, and (iii) immediate changes in blood flow and vascular structure, resulting in prolonged and complete vascular shutdown. Monte Carlo modeling resulted in a 53.2% and 69.0% higher absorbed energy distribution in the top half and the total simulated vessel when comparing the composite narrowband IPL to the 595 nm (PDL), respectively. Conclusions Our data collectively demonstrate the potential to achieve removal of vascular lesions using a 500–600 nm range. Additionally, the narrowband IPL was tuned to optimize a specific wavelength range that can be used to treat PWS, whereas the PDL can only operate at one discrete wavelength. Lasers Surg. Med.
