Abstract BACKGROUND: With the use of indocyanine green (ICG) as a novel fluorescent dye, fluorescence angiography has recently reemerged as a viable option. OBJECTIVE: To show the result of ICG videoangiography in cases of cerebral arteriovenous malformations. METHODS: Twenty-seven ICG videoangiography procedures were performed in 11 patients with cerebral arteriovenous malformations. Intraoperative digital subtraction angiography (DSA) was performed 27 times in these patients. The timing of intraoperative DSA was before dissection, after clipping of feeders, and after dissection of the nidus. RESULTS: The procedures were performed in 4.7 ± 1.4 minutes (mean ± SD; n = 27 minutes), whereas intraoperative digital subtraction angiography was performed for a mean of 16.6 ± 3.8 minutes (n = 27 minutes). In predissection studies, feeders were visualized by ICG in 3 of 9 cases. The nidus was visualized in all 9 cases, and drainers were visualized in 8. Intraoperative DSA visualized the feeders, nidus, and drainers in all 9 cases. After clipping of feeders, ICG videoangiography showed flow reduction of the nidus in 7 of 7 cases. Intraoperative DSA also showed that finding in 9 of 9 cases. After total dissection of the nidus, all cases disclosed that the drainers were without ICG filling. Intraoperative DSA also showed that result in all of the cases. Unexpected residual nidus was not visualized in our series with either method. CONCLUSION: We found that ICG videoangiography is helpful for resecting cerebral arteriovenous malformation. It is especially effective in visualizing the nidus and superficial drainers, as well as changes in flow after clipping or coagulating of feeders.

BACKGROUND: Cerebral digital subtraction angiography (DSA) has established impaired hemodynamic drainage of intracranial arteriovenous malformations (iAVM) as a risk factor for iAVM hemorrhage. Unlike conventional DSA, MR-DSA offers a noninvasive means of characterizing iAVM hemodynamics. We hypothesize that MR-DSA will demonstrate impaired drainage in iAVMs with history of rupture when compared to iAVMs without history of rupture. METHODS: Consecutive patients with untreated, DSA-confirmed iAVM underwent MR-DSA on a 3T Whole-body MR-scanner. For each iAVM, regions of interest (ROI) were drawn on all feeder arteries and draining veins. Time-density curves were constructed for each ROI. The arteriovenous malformation transit time (ATT) was defined for each ROI as the time between contrast arrival and peak intravascular contrast density on the MR time-density curve. The drainage of each iAVM was characterized by the ratio of the draining vein ATT to the mean feeder artery ATT. The ATT ratio was compared between iAVMs with history of hemorrhage and those without. Statistical analysis was performed using a Student’s unpaired t-test with p <0.05 defined as statistically significant. RESULTS: From May 2011 to April 2012, 13 patients (7M:6F, 40.6±13.8 years old) were enrolled in our study, with 3 patients presenting with history of hemorrhage and the remainder presenting with history of seizure, focal neurological deficit, headache, or as an incidental finding. The ATT ratio was significantly higher in iAVMs with history of hemorrhage than in those without (1.17±0.06 vs 0.95±0.02, p <2.9E-7). CONCLUSION: MR-DSA identifies impaired drainage in iAVMs with history of rupture without exposing patients to the procedural risks and ionizing radiation associated with cerebral DSA.

Scrotal Mass

Arteriovenous malformations (AVMs) of the scrotum are rare lesions, usually diagnosed incidentally during the evaluation of scrotal masses or infertility. It could be presented with acute bleeding or acute pain. We are presenting a case of painless bilateral infiltrated scrotal mass (more advanced in the left side) developed dramatically over a year, no other symptoms existed. The diagnosis was made using duplex ultrasound (DUS), computed tomography arteriography (CTA), and digital subtraction angiography (DSA). Three sessions of angioembolization were performed and followed by surgical resection of the left side of the scrotum.

Abstract OBJECTIVE Reliable and rapid delineation of arteriovenous malformations enables the application of effective treatments such as stereotactic radiosurgery. We describe a new method to improve the speed and reliability of visualizing the flow of contrast images with digital subtraction angiography. METHODS In line with current practices, digital subtraction angiography was used to produce a sequence of grayscale images. The new method combines the standard grayscale images produced by digital subtraction angiography into a single composite color image that encodes the contrast arrival time at each point of the brain's circulatory system. The algorithm is simple, fast, and easy to implement. RESULTS The technique allows the flow of contrast from a series of angiography images to be summarized in a single color image. CONCLUSION This visualization method promises to improve the speed of manual delineation of arteriovenous malformations. Further studies are required to evaluate the clinical value of the use of color intensity projection images, supplemented by grayscale images as necessary, in comparison with contouring on grayscale images only.
