Retrograde embolization of internal iliac artery aneurysms that enlarged after proximal ligation: A report of 5 patients.

The transarterial approach is generally feasible for endovascular treatment of internal iliac artery aneurysms (IIAAs). However, this approach becomes difficult in patients who have undergone exclusion surgery (proximal ligation). We report our experience of performing transcatheter arterial embolization (TAE) using a retrograde approach from the deep femoral artery (DFA) for IIAAs that had enlarged after exclusion surgery.

Vascular type Ehlers-Danlos syndrome with intra-abdominal hemorrhage due to ruptured hepatic aneurysm: A case report.

Background: Vascular Ehlers-Danlos syndrome has a high mortality rate due to hemorrhagic complications.

Case Presentation: We report a case of vascular-type Ehlers-Danlos syndrome diagnosed due to rupture of multiple celiac aneurysms. The patient was a 25-year-old Japanese man with a history of a sigmoid perforation.

An anomalous left adrenal vein draining into both the left renal vein and inferior vena cava: A case report.

A male patient in his forties was diagnosed with primary aldosteronism following blood tests. The patient requested surgical treatment and was transferred to our department for adrenal vein sampling. Preoperative contrast-enhanced computed tomography (CT) revealed that the left adrenal vein (LAV) did not form a common trunk with the left inferior phrenic vein, and instead drained into both the left renal vein (LRV) and inferior vena cava (IVC) after the bifurcation.

Successful coil embolization of post-hepatectomy arterioportal fistula that reduced ascites and improved liver function.

A 71-year-old man had previously undergone S7 + S8 dorsal segmentectomy and S5 partial hepatectomy for hepatocellular carcinomas. Six months later, he experienced abdominal distention. Abdominal computed tomography (CT) showed massive ascites and a significant hepatic arterioportal shunt.

Successful retrieval of a foreign body in an infant's right pulmonary artery using the new boomerang loop-snare technique: A case report.

We report successful percutaneous retrieval of a foreign body located in an infant's right pulmonary artery using the new boomerang loop-snare technique. The case was an 18-month-old girl. A central venous catheter for chemotherapy was inserted from the right subclavian vein during treatment for myelodysplastic syndrome at another hospital.
