Abstract

Objectives

To report e experience of performing embolization procedure of aneurysms with mechanical detachable coils(MDC).

Methods

Two patients underwent embolization of eneurysms with mechanical detachable coils. One patient who had an aneurysm in the left posterior inferior cereberllar artery(PICA) underwent the embolization procedure with one spiral coil(4mm×80mm) and another patient who had an aneurysm in the left posterior(P-comm.) communicating artery aneurysm underwent the embolization procedure with four spiral coils(three 5mm×8mm and one 3mm×80mm).

Results

Immediately after coil placement in the PICA the flow of contrast in the PICA reduced significantly. It may resulted from compression of the origin of PICA by the coil-packed aneurysm. The posttreatment course was not uneventful In case of P-comm. aneursym, the last coil(3mm×80mm) which embolized in the aneurysm, escaped from the aneurysm into the left internal carotid artery. Thej retrieval of the coil in the internal carotid artery with 3F microretrieval cathter was sucesfully performed.

Conclusion

This preliminary experience suggests that the embolization procedure with mechanical detachable coils is a usful modality of treatment of cerebral aneurysm in case ofinoperable cases.
