RODRIGUEZ-VARELA, Rodolfo e SAAL-ZAPATA, Giancarlo. Usefulness of intra-operative angiography for surgical treatment of arteriovenous malformations and intracranial aneurysms. Rev Med Hered [online]. 2022, vol.33, n.3, pp.173-177. Epub 03-Nov-2022. ISSN 1018-130X. http://dx.doi.org/10.20453/rmh.v33i3.4337.
Objective:
To determine the utility of intraoperative angiography (IOA) to detect residual lesions after surgical repair of arteriovenous malformations (AVM) and intracranial aneurysms (ICA).
Methods:
This is a case series including 778 patients from November 1993 to April 2001; of which 477 underwent surgical intervention. IOA was used in 119 cases.
Results:
A total of 119 cases were analyzed, 105 patients with AVM (88.2%) and 14 with an aneurysm (11.8%). The mean age was 35 years (range 6 - 69) and males represented 52% of the cases. Both AVM and aneurysms occurred in 17 cases (14.3%). Giant paraclinoid aneurysm was the most common aneurysm (71.3%), whereas supratentorial and grade 3 Spetzler-Martin AVM represented 83.3% and 73.3% of the cases, respectively. A residual lesion was was detected in 7 cases, of which 5 were residual nidus of an AVM and 2 remnant aneurysms. IOA-related complications occurred in 3.4% and mortality was 2.5%.
Conclusions:
IOA is a useful technique to detect residual cerebro-vascular lesions after open surgeries
