Treatment of severe hyperlipidemia: six years' experience with low-density lipoprotein apheresis.

abstract：:Giant cerebral aneurysms may be untreatable by conventional neurosurgical techniques. Early attempts to use circulatory assistance and deep hypothermia were abandoned due to hemorrhagic complications. More recently, interest in circulatory support for complex neurosurgical procedures has been renewed. A consecutive se...
