We here present a case involving a complicated type of gastric fundal varices treated by balloon-occluded retrograde transvenous obliteration. A newly developed 1.8-Fr tip coaxial microballoon catheter was successfully advanced into narrow and tortuous varices, and a sclerosant could be infused in a reasonable manner, avoiding reflux into collaterals. Divided injections of sclerosant were performed over two days, via a microballoon catheter that remained inserted overnight with balloon inflation, and the sclerosant could be infused sufficiently in the entirety of the varices...

Endovascular coil embolization using a balloon- or stent-assisted technique for the treatment of wide-necked posterior communicating artery (PcomA) aneurysms is well established. However, complete aneurysm occlusion with preservation of the PcomA can be difficult in case of wide-neck aneurysms with a PcomA incorporation. We present two cases of stent-assisted coil embolization using a retrograde approach through the posterior circulation for wide-neck or branch-incorporated PcomA aneurysms. Retrograde stenting was successful without periprocedural complications...

Arteriovenous malformations (AVMs) are a high-flow form of a vascular malformation, which can be found anywhere in the body. While historically treated surgically, a multidisciplinary approach utilizing multiple specialties and treatment modalities is now commonly employed. In order to effectively treat an AVM, the nidus must be targeted and eradicated, which can be done via multiple approaches. We present the case of a 43-year-old male with a gastric wall AVM, which was initially incompletely treated using a percutaneous transarterial approach...

AIM: To evaluate whether intra-procedural cone-beam computed tomography (CBCT) performed during modified balloon-occluded retrograde transvenous obliteration (mBRTO) can accurately determine technical success of complete variceal obliteration. METHODS: From June 2012 to December 2014, 15 patients who received CBCT during mBRTO for treatment of portal hypertensive gastric variceal bleeding were retrospectively evaluated. Three-dimensional (3D) CBCT images were performed and evaluated prior to the end of the procedure, and these were further analyzed and compared to the pre-procedure contrast-enhanced computed tomography to determine the technical success of mBRTO including: Complete occlusion/obliteration of: (1) gastrorenal shunt (GRS); (2) gastric varices; and (3) afferent feeding veins...

We present the case of a 50-year-old man with Cushing syndrome caused by an ectopic adrenocorticotropic hormone (ACTH)-secreting tumor. A small nodule was located in close association with the lateral segmental branch of the pulmonary artery in the left upper lobe. Blood samples were obtained from various branches of the pulmonary artery by balloon-occluded retrograde sampling for the measurement of location-specific serum ACTH levels. After confirmation that the pulmonary nodule was responsible for the increased ACTH secretion, lobectomy was performed...

Bleeding from gastroesophageal varices (GEV) is a serious event in cirrhotic patients and can cause death. According to the explosion theory, progressive portal hypertension is the primary mechanism underlying variceal bleeding. There are two approaches for treating GEV: primary prophylaxis to manage bleeding or emergency treatment for bleeding followed by secondary prophylaxis. Treatment methods can be classified into two categories: 1) Those used to decrease portal pressure, such as medication (i.e., nonselective β-blockers), radiological intervention [transjugular intrahepatic portosystemic shunt (TIPS)] or a surgical approach (i...

A 66-year-old male patient with liver cirrhosis because of alcohol intake underwent a Hartmann's procedure for rectal cancer. Four months later, bleeding from the sigmoid stoma occurred and persisted for 2 months. A colonoscopic examination revealed bleeding from stomal varices. Three-dimensional computed tomography (CT) imaging demonstrated the inferior mesenteric vein and left superficial epigastric vein as the feeding and drainage vessels, respectively. Balloon-occluded retrograde transvenous obliteration (B-RTO) through the left epigastric vein was performed using a microballoon catheter inserted from the right femoral vein according to the Seldinger method...

AIM: To clarify the long-term outcome of therapeutic strategies including balloon-occluded retrograde transvenous obliteration (B-RTO) for patients with gastric fundal varices. METHODS: The subjects were 154 patients with gastric fundal varices fulfilling the criteria for receiving B-RTO. In patients showing variceal bleeding, endoscopic therapies and/or balloon tamponade was done to achieve hemostasis. B-RTO was accomplished with injection of 5% ethanolamine oleate through a standard-balloon catheter except for patients with atypical varices, in whom a microballoon catheter was used to occlude drainage vessels other than a gastrorenal shunt...
