Renal angiomyolipoma (AML) and aneurysm are common in tuberous sclerosis complex (TSC) and represent the main causes of morbidity in adults with TSC. Herein, we report a 22-year-old woman with TSC-associated AMLs and renal aneurysms. She was referred to our hospital for the treatment of multiple renal aneurysms larger than 5 mm in diameter. The previous hospital considered that transcatheter arterial embolization (TAE) of bilateral renal aneurysms would cause deterioration of renal function. To estimate the impact of TAE on renal function, we superimposed contrast enhanced computed tomography (CT) over single-photon emission CT (SPECT)-CT...

Balloon-occluded transarterial chemoembolization (B-TACE) is a valuable treatment option for patients with inoperable malignant tumors in the liver. B-TACE consists of the transcatheter infusion of an anticancer drug mixture and embolic agents. Contrary to conventional TACE, B-TACE is performed via an artery-occluding microballoon catheter, which makes the blood-flow to redistribute due to the intra- and extrahepatic arterial collateral circulation. Several recent studies have stressed the importance of the redistribution of blood-flow in enhancing the treatment outcome...

BACKGROUND: Pulmonary arteriovenous malformations (PAVMs) can be associated with life-threatening complications such as paradoxical embolization, cerebral abscess, and hemothorax. Therefore, all adults with PAVMs should be offered treatment. Percutaneous transcatheter embolization is the first-line treatment, but 5-25% of cases require further treatment due to persistence after embolization. Recently, the role of minimally invasive thoracic surgery as a definitive treatment has been evaluated...

Hemoptysis is a life-threatening complication of Behcet's disease that is likely related to pulmonary artery aneurysm (PAA). Vascular interventional radiology may offer effective emergency therapeutic option, but has not been thoroughly investigated in this setting. A case series of a French referral center for hemoptysis combined with a literature review of case reports was conducted. Between 1995 and 2016, 12 patients were referred to our center for hemoptysis revealing or complicating the course of Behcet's disease...
