ABSTRACT Major liver resections require extensive margins. Occasionally, insufficient parenchyma is available after surgery to maintain liver function. In such cases, vascular embolization in the affected lobe is necessary to induce contralateral lobe hypertrophy. We present a case of embolization of the right portal and hepatic veins prior to intrahepatic cholangiocarcinoma resection. Embolization was performed because of insufficient residual parenchyma on imaging studies. The patient recovered well with no signs of liver failure, and remains in remission at 3 years […]

ABSTRACT In Brief Angiography of the superior rectal artery showed that its branches were divided into four main branches (two left and two right) in 46.8%; the second most frequent variation was one right and two left branches in 26.6%, followed by two branches to the right and one to the left in 20%; the most uncommon variations were one to the right and one to the left without further subdivision in 6.6%. Highlights The superior rectal artery, when it […]

ABSTRACT Objective To evaluate improvement in quality of life, reduction of uterine volume, and the correlation between these two variables after uterine fibroid embolization. Methods Data on quality of life before and after uterine fibroid embolization were collected from 60 patients using the Uterine Fibroid Symptom – Quality of Life questionnaire. In 40 of these patients, uterine volume information on magnetic resonance imaging examinations performed before and after uterine fibroid embolization was collected, and compared using the nonparametric Wilcoxon test […]

ABSTRACT Varicose gastrointestinal bleeding is one of the major causes of morbidity and mortality in patients with chronic liver disease. Endoscopic treatment is the first therapeutic line for these patients, however, for those whom this therapeutic modality fail, a broad knowledge of alternative treatment options may improve the prognosis. We describe a case of a patient who were successfully embolized from gastroesophageal varices via transsplenic access.

Hepatocellular adenoma is a rare benign tumor that was increasingly diagnosed in the 1980s and 1990s. This increase has been attributed to the widespread use of oral hormonal contraceptives and the broader availability and advances of radiological tests. We report two cases of patients with large hepatic adenomas who were subjected to minimally invasive treatment using arterial embolization. One case underwent elective embolization due to the presence of multiple adenomas and recent bleeding in one of the nodules. The second […]

ABSTRACT Endovascular surgery has presented a high evolution since 1960 with Charles Dotter, who changed the concept of catheter utilization as a mean to diagnose and introduce therapeutic in interventionist vascular environment. The first reports of bleeding control of gastrointestinal and transluminal angioplasty input the development of new techniques for endovascular access, and new materials use, such as microcatheters and embolic agents, become this procedure effective and viable for treatment of several pathologies. The embolization of several organs of human […]
