“…Some reports have suggested that IA-ICG angiography uses a minimum dose of ICG; thus, it has a short washout period and facilitates repeat examinations. [6,12] In our case, only a dose of 0.06 mg was used per injection in one examination. Horie et al have reported about two cases of spinal dAVF with multiple drainers that were successfully treated with repeat IA-ICG angiography.…”

Background: In this study, we report a case of dural arteriovenous fistula (dAVF) that was successfully treated using intra-arterial indocyanine green (IA-ICG) videoangiography during open surgery. Moreover, the findings of IA-ICG videoangiography were compared with those of intraoperative digital subtraction angiography (DSA). Case Description: A 72-year-old male patient with a history of hypertension, hyperlipidemia, and thrombocytosis presented with generalized seizure. DSA revealed Cognard Type III dAVF in the superior wall of the left transverse sinus, which was fed by a single artery (the left occipital artery [OA]) and drained into a single vein (the left temporal cortical vein), without drainage into a venous sinus. Since transarterial embolization was considered challenging due to the tortuosity of the left OA, surgical interruption of the shunt was performed by craniotomy. After excising the feeding artery, we were unable to observed dAVF on intraoperative DSA. However, IA-ICG videoangiography revealed the remaining shunt, which was fed by the collateral route from the feeding artery. The shunting point and draining vein were then surgically resected to eliminate the shunt. The shunt was not observed during the second IA-ICG videoangiography conducted after resection. Conclusion: ICG videoangiography is a better method compared with DSA in terms of visualizing fine vascular lesions. In contrast to the typical intravenous administration, selective IA-ICG can be repeatedly injected at a minimal dose. IA-ICG is a useful intraoperative tool that can be used to evaluate the elimination of the dAVF.

“…Superselective arterial injection of ICG (SAI-ICG) is an effective method for the identification of feeding arteries and draining veins during surgery for spinal AVSs. 2 The technique requires a very small amount of ICG, which is rapidly washed out, facilitating repeated examinations in a short period. Furthermore, SAI-ICG allows for visualization of the lesions from only the feeding artery, where the catheter is placed, while intravenous administration of ICG makes the whole lesion fluoresce at once.…”

“…We used a 1.6-2.1-Fr microcatheter to prevent "catheter kickback" as mentioned in a previous report. 2 For the superselective fluorescent angiography of the segmental artery, approximately 2 mL of a contrast medium was injected into the microcatheter. During SAI-ICG, the observation mode of the operating microscope (Zeiss, OPMI PENTERO 900) was changed from the bright field mode to the NIR (near-infrared) mode.…”

The usefulness of superselective arterial injection of indocyanine green (SAI-ICG) during the surgical treatment of a spinal arteriovenous shunts (AVSs) has occasionally been reported. However, SAI-ICG lacks the temporal resolution for recording rapid blood flow. The authors found that SAI of saline (SAIS) via a microcatheter renders the vessels transparent because of the replacement of intravascular blood with saline. By combining SAIS with SAI-ICG, they were able to identify abnormal vessels in the bright field during the surgical treatment of spinal AVS. Furthermore, they performed slow-motion video recording of blood flow in abnormal vessels by mounting a high frame rate (HFR) digital camera on the microscope eyepiece during SAIS. In this paper, the authors present two cases of patients with spinal AVSs. The first patient had a cervical dural arteriovenous fistula, and the second had a thoracic spinal arteriovenous malformation. SAIS delineated abnormal vessels within the bright field in real time in both cases. HFR video was recorded in the second case during SAIS. The slow-motion video showed a smooth and seamless motion of the blood flow in the feeding artery, which facilitated an understanding of the blood flow direction.
