To present a retrospective post-pancreaticoduodenectomy case series that had sentinel bleeding after pancreaticoduodenectomy and to evaluate the necessity and safety of prophylactic embolization. Fifteen post-pancreaticoduodenectomy patients with sentinel bleeding after pancreaticoduodenectomy were included in this study. Digital subtraction angiography was performed 6 hours after sentinel blee...

Background. Gastrinomas are rare functional neuroendocrine tumors causing the Zollinger-Ellison syndrome (ZES). At presentation, up to 25% of gastrinomas are metastasized, predominantly to the liver. Embolization of liver metastases might reduce symptoms of ZES although a postembolization syndrome can occur. In this study, the results of embolization are presented, and the literature results ar...

In order to determine possible risk factors and to assess the value of platinum microcoils added to polyvinyl alcohol particles in preoperative embolization of cerebral arteriovenous malformations in adults, we reviewed our experience with this procedure. Between September 1985 and June 1989, we performed embolizations in 54 patients with cerebral arteriovenous malformations. Of these, procedur...

BACKGROUND Renal angiomyolipoma is rare, but many of these patients may have an acute debut with severe bleeding. These patients need urgent treatment with interventional embolization as an attractive option. PURPOSE To investigate the technical and clinical effect of this treatment and to evaluate long-term clinical outcomes with clinical control and radiological imaging. MATERIAL AND METH...

BACKGROUND AND PURPOSE Corporectomy is an effective treatment for vertebral metastases; however, massive perioperative hemorrhage is often associated with this procedure. We compared preoperative particle, particle-coil, and coil embolizations of hypervascular spinal tumors prior to vertebral body replacement to determine which prevented perioperative hemorrhage most effectively. METHODS The ...

PURPOSE We aimed to evaluate the feasibility and safety of selective arterial embolization for refractory knee hemarthrosis. MATERIALS AND METHODS Transcatheter arterial embolization for refractory knee hemarthrosis was performed on five female patients (median age, 77 years; range, 71-80 years) between May 2009 and September 2012. Selective arterial embolization of the feeding artery was per...

PURPOSE To determine whether subclinical cholesterol embolization is a frequent sequela of thrombolytic therapy. Case reports of catastrophic cholesterol embolization temporally associated with thrombolytic therapy in 19 patients have suggested a causal relationship. PATIENTS AND METHODS We prospectively followed 60 patients with acute myocardial infarction who underwent coronary bypass surge...

  The method and results for preoperative embolization are described in 36 cases with intracranial meningiomas. Embolization materials were injected through a transfemoral catheter, selectively placed in the external carotid artery. Chopped gelfoam served as embolization material in 29 pa tients and ivalon particles were used in 7 patients. In 19 out of 36 cases the feeding arteries arose ...

BACKGROUND AND PURPOSE The purpose of this study was to assess the frequency, severity, and predictors of neurological deficits after adjuvant embolization for cerebral arteriovenous malformations. METHODS From 1997 to 2006, 202 of 275 patients with arteriovenous malformation received embolization before microsurgery (n=176) or radiosurgery (n=26). Patients were examined before and after endo...

A 34-year-old man had a transient ischemic attack and subsequently a completed stroke. Arteriography revealed a large fusiform aneurysm of the left middle cerebral artery with intraluminal thrombus. At surgery, the thrombus was seen within the lumen of the aneurysm. Absolute evidence for embolization is lacking as no examination for this could be done. Embolization from intracranial aneurysms s...
