Oclusão de fístula arteriovenosa pulmonar com plug vascular em paciente com embolia cerebral paradoxal prévia

Abstract: Fístula arteriovenosa pulmonar (FAVP), uma rara anormalidade vascular, é uma comunicação direta entre a artéria e a veia, sem a interposição do leito capilar, representando shunt extracardíaco direito-esquerdo.1 Quando significativa, pode causar sinais e sintomas clínicos, tais como fadiga fácil, dispneia de esforço, cianose, hemoptise e complicações importantes como abscesso cerebral, ataque isquêmico transitório e acidente vascular encefálico. 2Neste artigo, descrevemos o caso de uma paciente com FAVP que ap… Show more

“…However, there is evidence that percutaneous treatment with occlusion reduces the probability of cerebral embolization, and this treatment is indicated in all symptomatic patients (cyanosis, dyspnea and paroxysmal embolism) and in those who present with a fistular sac >3mm in diameter, due to a higher incidence of embolic events. 8 In cases with large caliber fistulas, in which the use of coils is not feasible due to the chance of their embolization and important complications, the use of vascular plugs, associated or not with coils, is the best approach, as also described in the case reports by Erudilho et al 8 and Faria et al 9 The surgical approach is restricted to complex cases, when the supplying arteries have very large calibers, and the vascular anatomy does not favor percutaneous intervention, or cases with unsuccessful embolization and/or that have not achieved satisfactory results. 11 In the three cases, a surgical approach was not necessary after the percutaneous procedure.…”

“…The results reproduce those observed in other studies. 8,9 The adequate and precise choice of material to be used for the percutaneous closure is important to reduce procedure failure and complications. Treatment options include percutaneous embolization with coils, a detachable balloon, or other devices, as well as surgical excision.…”
