Abstract

SUMMARY: This report describes the management of a fusiform peripheral middle cerebral artery aneurysm by endovascular parent artery occlusion under bypass protection. Localization of the recipient cortical artery was accomplished after craniotomy by superselective injection of diluted ICG dye via a microcatheter positioned proximal to the aneurysm. This report demonstrates that superselective ICG angiography can be a beneficial alternative technique to identify the best anastomosis site intraoperatively.

Intracranial fusiform aneurysms occurring beyond the circle of Willis are rare and challenging lesions.1⇓⇓⇓–5 Possible therapeutic strategies include deconstructive techniques such as trapping and endovascular PAO as well as reconstructive techniques such as direct clipping and stent reconstruction.1,4,6⇓⇓⇓⇓–11 Deconstructive procedures are often performed under bypass protection to preserve cerebral perfusion distal to the occluded aneurysm.3⇓–5 Correct localization of the cortical recipient artery distal to the aneurysm is of importance for selective revascularization. Identification of this branch is possible by surgical dissection, neuronavigation, and stereotactic techniques as well as intraoperative DSA.12⇓⇓–15

In this technical case report, we describe the management of a fusiform peripheral MCA aneurysm by endovascular PAO under bypass protection. Localization of the recipient cortical artery was accomplished after craniotomy by superselective injection of diluted ICG dye via a microcatheter positioned proximal to the aneurysm.1,16 Fluorescent activity in the corresponding distal cortical artery was detected under the operation microscope.

Case Report/Technique

A 21-year-old woman was admitted with the incidental MR imaging finding of a 10-mm vascular lesion in the posterior limb of the left insular cistern (Fig 1A). DSA disclosed a fusiform peripheral MCA aneurysm (Fig 1B). In view of the eloquence of the dependent distal vascular territory, surgical trapping and endovascular PAO were considered impracticable. Stent reconstruction of the aneurysm was considered but deferred because of the tortuosity of the aneurysm and the caliber mismatch between the proximal and distal parent arteries. The decision was made to occlude the aneurysm under bypass protection. Because the team of vascular neurosurgeons involved in the management of cerebral aneurysms at our center is cross-experienced in the surgical and endovascular management of cerebrovascular lesions, a strategy of endovascular PAO immediately after bypass surgery was developed.

A 5F sheath was placed at the right groin and a 5F macrocatheter was advanced into the left common carotid artery. The frontal branch of the superficial temporal artery was of sufficient size and was used as the donor vessel for an arterial low-flow bypass. After microsurgical dissection of this branch, craniotomy, and dural opening, an SL 10 microcatheter (Boston Scientific, Fremont, California) was coaxially advanced through the macrocatheter into the left MCA and navigated under fluoroscopic road-mapping control to a superselective position proximal to the aneurysm. Thereafter, selective angiograms were obtained, and the position and morphology of the distal cortical recipient artery were assessed (Fig 1C). ICG dye (ICG-PULSION; PULSION Medical Systems, Munich, Germany) was then applied via a peripheral vein (25 mg), and the morphology of the cortical vasculature at the craniotomy site was studied under an operation microscope (Zeiss Pentero; Carl Zeiss, Oberkochen, Germany; Fig 1D, –E). After 10 minutes, 2 mL of ICG dye diluted to 0.1 mg/ml was injected superselectively via the microcatheter into the parent artery of the aneurysm. Under the operation microscope, fluoroscopic activity could be detected selectively in the vascular territory supplied by the injected artery and a suitable cortical recipient artery could be identified easily (Fig 1F). After withdrawal of the microcatheter, bypass surgery was completed (Fig 1G). At the end of the operation, another microcatheter access to the aneurysm was performed, and endovascular PAO was accomplished by using detachable coils (Fig 1H). The correct localization of the anastomosis was verified by selective intraoperative DSA of the external carotid artery territory (Fig 1I).

Discussion

In this article, we describe the intraoperative identification of a cortical recipient artery for selective revascularization of a peripheral vascular territory. The technique described may not be necessary in all cases of small peripheral aneurysms, where the distal recipient artery may easily be identified by surgical dissection. However, when selective revascularization of a distal vascular territory is required in the management of larger or more complex peripheral aneurysms and endovascular expertise is available, this technique can be a reasonable alternative. Intraoperative microcatheter manipulations were easily possible, and monoplane imaging quality was comparable to that of standard endovascular angiography suites. Permanent flushing of all catheter systems with heparinized saline is mandatory to avoid thromboembolic complications and did not adversely affect coagulation intraoperatively. The concentration of the ICG dye for intra-arterial injection was adjusted to simulate arterial ICG concentrations after intravenous bolus injections. Because the operation room setup allowed for endovascular interventions and the catheter systems were already in place, the aneurysm was obliterated via the endovascular route. The most suitable surgical or endovascular technique to obliterate such aneurysms is usually chosen individually on a case-by-case basis, and it is not the purpose of this report to advocate either technique.

Conclusions

Peripheral intracranial aneurysms can be managed effectively by surgical or endovascular PAO under bypass protection.3⇓–5 When selective revascularization of a vascular territory distal to the aneurysm is required, localization of the correct cortical recipient vessel is of importance. Superselective ICG angiography as described in this report can be a beneficial alternative technique to identify the best anastomosis site intraoperatively.
