Supraclinoid Internal Carotid Artery

AbstractAnterior clinoidal meningiomas (ACMs) remain a major neurosurgical challenge. The skull base techniques, including extradural clinoidectomy and optic unroofing performed at the early stage of surgery, provide advantages for improving the extent of resection, and thereby enhancing overall outcome, and particularly visual function. Additionally, when the anterior clinoidal meningiomas encase neurovascular structures, particularly the supraclinoid internal carotid artery and its branches, this further increases morbidity and decreases the extent of resection. Although it might be possible to remove the tumor from the artery wall despite complete encasement or narrowing, the decision of whether the tumor can be safely separated from the arterial wall ultimately must be made intraoperatively.The patient is a 75-year-old woman with right-sided progressive vision loss. In the neurological examination, she only had light perception in the right eye without any visual acuity or peripheral loss in the left eye. MRI showed a homogeneously enhancing right-sided anterior clinoidal mass with encasing and narrowing of the supraclinoid internal carotid artery (ICA). Computed tomography (CT) angiography showed a mild narrowing of the right supraclinoid ICA with associated a 360-degree encasement. The decision was made to proceed using a pterional approach with extradural anterior clinoidectomy and optic unroofing. The surgery and postoperative course were uneventful. MRI confirmed gross total resection (Figs. 1 and 2). The histopathology was a meningothelial meningioma, World Health Organization (WHO) grade I. The patient continues to do well without any recurrence and has shown improved vision at 15-month follow-up.This video demonstrates important steps of the microsurgical skull base techniques for resection of these challenging tumors.The link to the video can be found at https://youtu.be/vt3o1c2o8Z0

We report our experience with endovascular treatment and follow-up results of a ruptured blood blister-like aneurysm (BBA) in the supraclinoid internal carotid artery. We performed a retrospective review of ruptured blood blister-like aneurysm patients over a 30-month period. Seven patients (men/women, 2/5; mean age, 45.6 years) with ruptured BBAs were included from two different institutions. The angiographic findings, treatment strategies, and the clinical (modified Rankin Scale) and angiographic outcomes were retrospectively analyzed. All seven BBAs were located in the supraclinoid internal carotid artery. Four of them were ≥ 3 mm in largest diameter. Primary stent-assisted coiling was performed in six out of seven patients, and double stenting was done in one patient. In four patients, the coiling was augmented by overlapping stent insertion. Two patients experienced early re-hemorrhage, including one major fatal SAH. Complementary treatment was required in two patients, including coil embolization and covered-stent placement, respectively. Six of the seven BBAs showed complete or progressive occlusion at the time of late angiographic follow-up. The clinical midterm outcome was good (mRS scores, 0–1) in five patients. Stent-assisted coiling of a ruptured BBA is technically challenging but can be done with good midterm results. However, as early regrowth/re-rupture remains a problem, repeated, short-term angiographic follow-up is required so that additional treatment can be performed as needed.

ABSTRACTIn the contemporary era of aneurysm management, large fusiform aneurysms presenting with subarachnoid hemorrhage (SAH) remain particularly challenging lesions to successfully manage. We describe a staged, multimodal treatment strategy for a 71-year-old patient who presented with a large ruptured fusiform aneurysm of the supraclinoid internal carotid artery (ICA) and a fetal posterior communicating artery which originated from the inferomedial aspect of the aneurysm. In the first stage, we performed a partial microsurgical clip reconstruction of the fusiform aneurysm and secured its rupture site, which was identified intraoperatively. This left two residual saccular components of the aneurysm, which were targeted with endovascular coiling in the same hospitalization after the patient had convalesced from the SAH and was beyond the vasospasm window. We believe that this combined approach of clip-assisted coiling can be employed instead of endovascular flow diversion or microsurgical bypass for appropriately selected patients with ruptured fusiform ICA aneurysms.

Supraclinoid Internal Carotid Artery

ABSTRACT OBJECTIVE Aneurysms at nonbranching sites in the supraclinoid internal carotid artery (ICA), known as blood blister-like aneurysms or ICA anterior or dorsal wall aneurysms, are not well understood. To clarify this clinical entity, 7408 patients with subarachnoid hemorrhage who were treated during a 5-year period were analyzed. METHODS Forty-eight patients had aneurysms that were intraoperatively confirmed to be located at a nonbranching site in the supraclinoid portion of the ICA. Neuroradiological and clinicopathological features and outcomes were studied. RESULTS The aneurysms were divided into the “blister type,” with a blood blister-like configuration and fragile walls, and the “saccular type,” with a saccular configuration and a relatively firm neck, like ordinary berry aneurysms. The most frequent origin was the anteromedial wall for both types. ICA dissection was associated only with the blister type, and hypertension was more frequent with the blister type (P = 0.0978). The preoperative conditions of the patients were the same, but the outcomes for patients with blister-type aneurysms were worse, because of frequent intra- and postoperative aneurysmal bleeding. Saccular-type aneurysms were safely clipped. Treatment of blister-type aneurysms by clipping on wrapping material achieved good results, but ICA trapping (P = 0.0952), clipping (P = 0.0146), and wrapping (P = 0.0110) were associated with much worse results. CONCLUSION Blister-type and saccular-type aneurysms have different shapes and wall characteristics. The saccular type can be treated by clipping, whereas the blister type requires clipping on wrapping material. ICA trunk aneurysms may be a better designation to express the diversity of these aneurysms, rather than ICA blood blister-like or anterior or dorsal wall aneurysms.
