Fusiform aneurysms of the distal anterior cerebral artery (DACA) are infrequent. Clip reconstruction and sequential progressive clipping have been described in the management of giant thrombosed DACA aneurysms.1,2 Customized revascularization with bypass, side-to-side anastomosis, and trapping of the aneurysmal segment have also been performed for treating DACA aneurysms.3-12 We present a 2-dimensional operative video of superficial temporal artery (STA) to distal anterior cerebral artery bypass, followed by trapping of the aneurysm-bearing segment. A 57-yr-old lady presented with a large ruptured subcallosal fusiform DACA aneurysm (WFNS grade 1, Fisher grade 1). Angiography revealed a 1.3 × 0.9 cm fusiform aneurysm in the DACA.
Informed consent was secured from the patient and her family for the surgery and permission was obtained for the publication of the patient's image/surgical video. The frontal and parietal branches of the STA were dissected. The parietal branch was explanted and used as a free interposition graft between the frontal branch (end-to-end anastomosis) and calloso-marginal artery (end-to-side anastomosis). After confirming blood flow through the bypass using Doppler, the aneurysm was trapped and excised.
The patient had an uneventful recovery. Her postoperative computed tomography (CT) head revealed no evidence of neurological insult. The patency of the bypass conduit and the complete removal of the aneurysm were confirmed using a digital subtraction angiogram. Histopathological examination revealed an eccentric atheromatous plaque with a lipid core. There was no evidence of intraplaque hemorrhage. This extended STA graft utilizing the frontal and parietal branches of the STA, and its implantation into the distal ACA, offers a novel bypass strategy for tackling fusiform aneurysms of the DACA. Anastomosis to the calloso-marginal artery ensured perfusion of the ACA territory through the pericallosal artery during temporary occlusion.
Inter arma enim silent lēgēs (Latin) (In times of war, the laws fall silent).-CiceroEthical values and medicolegal fidelity are deeply ingrained in our surgical culture. Yet, these are often put to an acid test by cutting-edge technologies like robotic surgery (RS), where ethical and legal proprieties may at times be in peril. 1 Surgical endeavors are not just mechanical tasks, but a complex culmination of experience, anatomical familiarity, creativity, adaptability to variation, and emergency mayday measures, and are, thus, considered difficult to automate. 1,2 As surgical sciences catch up with the robotic revolution, the caring, empathetic, compassionate surgeon faces the threat of being outclassed by a faster, stronger, more learned, and efficient machine. [3][4][5] The spectrum of surgical possibilities in robotic competencies and levels of autonomy are rapidly expanding, creating moral, ethical, and medicolegal dilemmas and vulnerabilities. 1,2
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
