Quantitative Flow

ObjectivesTo evaluate the differences in arterial flow after flow diverter placement using quantitative flow measurements based on digital subtraction angiography (DSA).MethodsBetween November 2013 and November 2015, all patients who had flow diverters placed for distal internal carotid artery (ICA) aneurysms were reviewed. Patients in whom the stent was placed across the ostia of the ophthalmic artery (OphA) and anterior choroidal artery (AChA) were enrolled. Five regions of interest were selected: the proximal ICA (as a reference), terminal ICA, middle cerebral artery (MCA), anterior cerebral artery (ACA), OphA, and AChA. The values of the peak, time-to-peak (TTP), and area under the curve (AUC) were analyzed using a quantitative DSA technique.ResultsThe study enrolled 13 patients. The quantitative flow analysis showed improved flow in the terminal ICA (peak and AUC, p=0.036 and p=0.04, respectively), MCA (AUC, p=0.023), and ACA (AUC, p=0.006), and decreased flow in the OphA (peak and AUC, p=0.013 and p=0.005, respectively) and AChA (peak and subtracted TTP, p=0.023 and p=0.050, respectively) after flow diverter placement. Larger aneurysm volume was significantly correlated with decreased OphA flow after the procedure (peak and AUC, p=0.049 and p=0.037, respectively). Larger aneurysm volume also had a marginal correlation with increased distal ICA flow after the procedure, but this did not reach significance (peak and AUC, p=0.195 and p=0.060, respectively).ConclusionsWithout using extra contrast medium or radiation dosages, color-coded DSA enables quantitative monitoring of the cerebral circulation after flow-diverting treatment.

A 56-year-old female with a giant partially thrombosed unruptured carotid-ophthalmic aneurysm was treated with a Pipeline flow diverter. Three months after the procedure, in concomitance with the discontinuation of one of the antiplatelet medications, the patient suffered from a minor stroke and relapsing transient ischemic attacks. The angiography demonstrated the occlusion of the internal carotid artery, and a perfusion-weighted CT scan showed a condition of hypoperfusion. The patient underwent a double-barrel extraintracranial bypass. The postoperative course was uneventful and she has experienced no further ischemic events to date.

The authors report a rare case of sequentially developed bilateral internal carotid artery (ICA) fusiform giant aneurysms in a patient with pathologically confirmed intimal fibroplasia. Both ICA fusiform aneurysms were treated with multiple flow diverter insertion and were well-managed over the past 5.5 years of follow-up. The development of aneurysms in this rare disease entity appears to be a lifelong process based on the authors’ observations in serial angiographic follow-up studies. Reconstruction therapy using flow-diverting stents in this unique condition may be a safe and effective treatment modality.

This paper is a case report of a young patient after a major head trauma causing multiple skull base fractures. The trauma occasioned pseudoaneurysm (PSA) from intracavernous C4 segment of left internal carotid artery (ICA) protruding in the sphenoidal sinus. After two months, two episodes of massive epistaxis occurred. Consequently, the post-traumatic PSA was treated, after carotid occlusion test, with flow-diverter stent positioning. A computed tomography angiography study performed in the following days showed complete resolution of the post-traumatic PSA lesion and ICA patency.
