BACKGROUND: Complete AVM obliteration could be achieved through microsurgery,
endovascular techniques, or radiosurgery (focused radiation), in single or combined mannar.
Each treatment option has associated risks and benefits
AIM OF THE STUDY: Our clinical study presents a prospective study of cerebral AVMs
treated with endovascular embolization followed with gamma knife radiosurgery. We
analyzed the clinical and angioarchitectural outcomes as well as the complications. Finally
we tried to find out the predicting factors for the success of this combined modality
PATIENTS AND METHODS: Thirty nine patients with cerebral AVMs were treated
endovascular embolization followed with gamma knife radiosurgery at The International
Medical Centre in Cairo and studied analytically at THE Benha University
Hospital from the beginning of January 2016 to the end of December 2021.
RESULTS: Factors that may predict the outcome clinically are:
i. Age
ii. Pre interventional mRs.
iii. Nidal configuration.
iv. Spetzler-Martin grade.
v. AVM size
Factors that may predict the outcome radiologically are
i. AVM size.
ii. Nidal configuration.
iii. Spetzler-Martin grade.
CONCLUSIONS: Endovascular embolization followed by stereotactic radiosurgery is
considered a feasible management modality for most cases of grade III and Grade IV
lesions with satisfactory rates of nidal obliteration. |
