For anatomic and technical reasons, it is often difficult to achieve guiding-catheter stability in the segmental arteries during embolization of spinal vascular lesions. We have developed a segmental artery exchange technique using a thin-walled 4F nontapered catheter that is safe and achieves a stable guiding-catheter position. This catheter accommodates both the flow-guided and variable-stiff...

Arteriovenous malformations (AVMs) of the brain are rare, complex, vascular lesions that can result in significant morbidity and mortality. Modern treatment of brain AVMs is a multimodality endeavor, requiring a multidisciplinary team with expertise in cerebrovascular neurosurgery, endovascular intervention, and radiation therapy in order to provide all therapeutic options and determine the mos...

The proliferation indices (PIs) were determined in 33 meningiomas using two monoclonal antibodies to the Ki-67 antigen (Ki-67 and MIB1). PIs obtained using Ki-67 on frozen material were intermediate between the lowest and highest MIB1 PIs determined in paraffin wax sections. Preoperative embolisation did not influence Ki67 PI, but four of the 15 embolised tumours showed substantially increased ...

BACKGROUND Percutaneous thoracic duct embolization (TDE) is a safe, effective, and minimally invasive option for treating chylothorax. A recent report demonstrated the feasibility of ultrasound-guided intranodal lymphangiography as an alternative to pedal lymphangiography for visualization of the thoracic duct, promising relative technical ease and decreased procedure time for TDE. METHODS We...

Pseudoaneurysms are rare complications of chronic pancreatitis and are associated with a high mortality. In this article we demonstrate a novel utilization of endoscopic ultrasound (EUS) technology to embolize a large pancreatic pseudoaneurysm when gold standard therapies had proven futile.

Osteotomies are commonly carried out in orthopaedic surgery, particularly in limb reconstruction. Complications are uncommon provided that sufficient care is taken and a sound technique used. We describe three cases of formation of false aneurysm after osteotomy, with acute, delayed and asymptomatic onset. The diagnosis was supported by ultrasound investigation, and confirmed by angiography. Em...
