Access to the superficial femoral artery in the presence of a "hostile groin": a prospective study.
Lower limb angioplasty is commonly performed via antegrade common femoral artery (CFA) puncture, followed by selective superficial femoral artery (SFA) catheterization. Arterial access can be complicated by a "hostile groin" (scarring, obesity, or previous failed CFA puncture). We prospectively investigated color duplex ultrasound (CDU)-guided SFA access for radiological interventions. ⋯ The CDU-guided SFA puncture technique was both more effective than CDU-guided CFA access in patients with scarred groins, obesity, or failed CFA punctures and safer, with reduced screen times, radiation doses, and complications.

Multicenter Study Comparative StudyValue of single-dose contrast-enhanced magnetic resonance angiography versus intraarterial digital subtraction angiography in therapy indications in abdominal and iliac arteries.
The objective of the study was to prove the value of single-dose contrast-enhanced magnetic resonance angiography [three-dimensional (3D) ceMRA] in abdominal and iliac arteries versus the reference standard intra-arterial digital subtraction angiography (i.a. DSA) when indicating a therapy. Patients suspected of having abdominal or iliac artery stenosis were included in this study. ⋯ In 13/34 patients, a discrepancy was found concerning therapy decisions based on MRA findings versus therapy decisions based on the reference standard DSA. The results showed that the used MRA imaging technique of abdominal and iliac arteries is not competitive to i.a. DSA, with a high rate of misinterpretation of the MRAs resulting in incorrect therapies.

Case ReportsCerebral lipiodol embolism: a complication of transcatheter arterial chemoembolization for hepatocellular carcinoma.
We report a case of cerebral lipiodol embolism following transcatheter chemoembolization (TACE) for hepatocellular carcinoma. A 70-year-old woman with a large unresectable hepatocellular carcinoma underwent TACE. ⋯ Despite intensive care, the patient died 2 weeks later. The complication might have been due to systemic-pulmonary shunts caused by previous surgeries and/or direct invasion of the recurrent tumor.

Case ReportsSpontaneous hemothorax in neurofibromatosis treated with percutaneous embolization.
We evaluated the effectiveness of transcatheter arterial coil embolization therapy for the treatment of spontaneous hemothorax followed by aneurysm rupture in neurofibromatosis patients. Three patients were treated for massive hemothorax caused by arterial lesions associated with neurofibromatosis. Bleeding episodes were secondary to ascending cervical artery aneurysm and dissection of vertebral artery in 1 patient, and intercostal artery aneurysm with or without arteriovenous fistula in 2 patients. ⋯ In 1 patient, the ruptured ascending cervical artery aneurysm was well embolized but, shortly after the embolization, fatal hemorrhage induced by dissection of the vertebral artery occurred and the patient died. In the other 2 patients, the ruptured intercostal artery aneurysm was well embolized and they were successfully treated and discharged. Transcatheter arterial coil embolization therapy is an effective method for the treatment of spontaneous hemothorax followed by aneurysm rupture in neurofibromatosis patients.

Case ReportsCoil embolization of pancreaticoduodenal artery aneurysms associated with celiac artery stenosis: report of three cases.
Aneurysms of the pancreaticoduodenal artery are rare. Degeneration of pancreaticoduodenal arcade vessels due to these aneurysms is associated with celiac artery stenosis or occlusion. Untreated lesions enlarge progressively and may rupture spontaneously. ⋯ All patients were treated by percutaneous coil embolization of the aneurysm. The aneurysmal sac was successfully excluded and the native circulation was preserved. Endovascular surgery can be used to treat these aneurysms safely and permits retention of the native circulation.
