Abstract
Background:
Applying more than one clip for a complicated-shaped aneurysm is an established strategy, particularly for middle cerebral arteries (MCA). However, obliterating the cleft of the internal elastic lamina with a single clip is theoretically possible because the line is usually on a single plane. Crankshaft clips were reformed for that purpose decades ago, but are not widely used and have been described in almost no report ever since.
Methods:
To reconsider and describe the utility of crankshaft clips for complicated MCA aneurysms and to articulate the advantages and limitations of the clips, we meticulously analyzed a series of more than 150 cases in which the crankshaft clips were used, predominantly for treatment of MCA aneurysms, at Moriyama Memorial Hospital between August 2010 and December 2015.
Results:
Readjustment of the clip was not necessary in almost all cases, and the first application was the final one. None of the patients had morbidity or mortality related to the surgical technique. To date, we have not experienced any trouble or recurrence.
Conclusions:
Crankshaft clips are useful and safe for clipping of complicated MCA aneurysms.
