“…This vessel is rarely recognized on angiography (Lasjaunias, 1981). Allen et al (2005) found this artery more commonly on the left side in patients undergoing balloon occlusion tests. These authors suggested that such branches may potentially serve as collateral conduits during a balloon occlusion test of the internal carotid artery.…”

Microsurgical approaches to the skull base require a thorough knowledge of the microvasculature of this region. Interestingly, most standard texts of anatomy do not mention the branches of the internal carotid artery as it travels through the temporal bone and cavernous sinus. Although small and with often conflicting descriptions, these arterial branches may be of significance when contributing to the vascular supply of such pathological entities as meningiomas and vascular malformations. Furthermore, multiple anastomoses exist between these branches and branches of the external carotid artery, thus providing a potentially important collateral circulation between these two systems and thus retrograde flow needed to maintain the patency of the distal internal carotid artery (ICA) when this vessel is obstructed proximally. We review the literature regarding these branches of the internal carotid artery and their clinical significance.

“…BTO was first described by Serbinenko in 1974 and is currently a well established endovascular method of risk stratifying patients for cerebral ischemia during subsequent therapeutic embolization 6 9 10. In our case, focused clinical examinations at frequent intervals during the critical period were more sensitive than neurophysiologic testing with SSEPs or EEG which remained unchanged.…”

“…Although anatomic variation exists, the ILT has been identified to arise from the ICA in about 90% of cases 4 5. Cranial nerves (CN) III, IV, V1 and VI which course through the cavernous sinus receive vascular supply from the ILT and therefore are at risk during endovascular procedures 2 5 6. Although the cavernous portion of the carotid artery is often involved in dissection or thrombosis,3 CN deficits are rare because of collateral circulation from the external carotid artery or meningohypophyseal trunk 7 8…”

“…When BTO is performed in the cervical ICA, the possibility of false nega tive results due to the persistence of the collateral blood flow via the branches that spring from the ICA between the cervical region and the actual site of occlusion must be kept in mind. 23) Ischemic symptoms due to a hemodynamic mechanism occurred in one patient who was judged to be "partially toler ant by BTO" and underwent PAO alone as expected from the results of BTO. In this series, methods without PAO were selected in many patients (23/50), and there may have been bias in the treatment selection, but the tolerance to ischemia due to PAO is considered to have been sufficiently evaluated.…”

Objective: Permanent therapeutic occlusion of the carotid artery is one of the treatment options for patients with a large/ giant internal carotid artery aneurysm or tumor involving the neck or skull base. Balloon test occlusion (BTO) is performed to predict the tolerance of parent artery occlusion (PAO). The authors combined various modalities to improve the sensitivity of BTO. The purpose of this study is to present the efficacy of the multimodal BTO. Results: By multimodal assessment of BTO, 33 patients were considered tolerable, six were partially tolerable, and 11 were intolerable. Thirteen of 33 patients with predictive tolerance underwent PAO without bypass, and all but one showed no hemodynamic ischemia postoperatively. Three of six patients with predictive partial tolerance were treated by PAO with extracranial-intracranial bypass, and they experienced no hemodynamic ischemia. In contrast, one with predictive partial tolerance treated by PAO without bypass developed ischemic events as feared. Conclusion:The multimodal BTO is helpful to evaluate the tolerance of PAO and is a reliable predictor of postoperative ischemic events. It reduces risks and increases treatment safety for permanent therapeutic occlusion of the carotid artery.

Proximal intracranial internal carotid artery branches: prevalence and importance for balloon occlusion test

Abstract: The authors recommend that patients be screened during angiography studies performed prior to BOT in branches of the proximal intracranial ICA and that the site of BOT be moved distally if such branches are identified.
