Embolização arterial superseletiva para tratamento de angiomiolipoma em paciente com rim único
(Universidade Federal do Pará, 2016-06) GÓES JUNIOR, Adenauer Marinho de Oliveira; JEHA, Salim Abdon Haber; SALGADO, José Rui Couto
The authors report on a case of a young woman who had previously undergone a right nephrectomy due to renal angiomyolipomas, currently presenting voluminous angiomyolipomas of the remaining kidney. The patient’s urologist referred her for endovascular treatment. Superselective arterial embolization of one tumor (located at the inferior renal pole), was conducted successfully. Several attempts at selective catheterization were made to embolize the second angiomyolipoma (located at the superior lobe), without jeopardizing a significant amount of the surrounding renal parenchyma, but this ultimately proved not to be feasible. The procedure and recovery were uneventful. The patient was discharged on the first postoperative day and has been followed for 9 months with no complications. The authors provide a brief review of the indications, technical aspects and complications of endovascular treatment of renal angiomyolipomas and also discuss the advantages of the endovascular approach over surgical resection for this kind of tumor.

Selective vesical artery embolization for treatment of gross hematuria due to actinic cystitis
(Universidade Federal do Pará, 2015-12) GÓES JUNIOR, Adenauer Marinho de Oliveira; JEHA, Salim Abdon Haber; QUEIROZ, Marcus Vinicius Baptista
This article describes the case of a 46-year-old female patient who had been treated with radiotherapy for cervical cancer. She developed actinic cystitis with frequent episodes of severe hematuria. She required repeated catheterization to manage urinary retention, blood transfusions and hospital admissions. Conservative measures and attempts to achieve hemostasis by cystoscopy were unsuccessful at controlling bleeding. The patient therefore underwent endovascular treatment with superselective embolization of the vesical arteries and other vascular pedicles found to be linked with the bleeding. The procedure was successful and the patient has been in follow-up for 9 months with no need for further blood transfusions or admission to hospital. According to a review of the literature, use of this technique has not previously been described in Brazil.

Tratamento endovascular de angiomiolipoma renal por embolização arterial seletiva
(2012-12) PALÁCIOS, Renato Menezes; GÓES, Amanda Silva de Oliveira; AGUIAR, Maurício Figueiredo Massulo; RIBEIRO, Flávio Roberto Cavalleiro de Macêdo; GÓES JUNIOR, Adenauer Marinho de Oliveira
We report a case of a patient with a major complaint of left lumbar pain, diagnosed with bilateral renal angiomyolipomas (AMLRs), with the most voluminous lesion of 6.2 cm in its largest diameter, underwent endovascular superselective arterial embolization with microspheres. The AMLRs are rare benign tumors. Most are sporadic, while a minority is associated with Tuberous Sclerosis Complex (ETC). The AMLRs larger than 4 cm must be treated due to higher risk of complications, especially hemorrhagic. A selective arterial embolization (EAS) is an effective and safe treatment for AMLRs.
