Long-term follow-up of patients with extensive segmental infantile hemangioma of the cervical or facial region: A French single-center prospective study.

BACKGROUND: Infantile hemangiomas (IHs) can be part of PHACE (posterior fossa anomalies, hemangioma, arterial anomalies, cardiac anomalies, eye anomalies) syndrome when they are segmental, extensive, and located on the face or neck. The initial assessment is codified and well known, but there are no recommendations for the follow-up of these patients. The aim of this study was to assess the long-term prevalence of different associated abnormalities. METHODS: Patients with a history of large segmental IHs of the face or neck. diagnosed between 2011 and 2016 were included in the study. Each patient underwent an ophthalmological, dental, ENT (ear, nose, and throat), dermatological, neuro-pediatric, and radiological assessment at inclusion. Eight patients including five with PHACE syndrome were prospectively evaluated. RESULTS: After a mean follow-up of 8.5 years, three patients presented with an angiomatous aspect of the oral mucosa, two with hearing loss, and two with otoscopic abnormalities. No patients developed ophthalmological abnormalities. The neurological examination was altered in three cases. Brain magnetic resonance imaging follow-up was unchanged in three out four patients and revealed atrophy of the cerebellar vermis in 1 patient. Neurodevelopmental disorders were found in five of the patients and learning difficulties were observed in five patients. The S1 location appears to be associated with a higher risk of neurodevelopmental disorders and cerebellar malformations, while the S3 location was associated with more progressive complications, including neurovascular, cardiovascular, and ENT abnormalities. CONCLUSION: Our study reported late complications in patients with a large segmental IH of the face or neck, whether associated with PHACE syndrome or not, and we proposed an algorithm to optimize the long-term follow-up.

Diagnostic performance of mobile cone beam computed tomography versus conventional multi-detector computed tomography in orbital floor fractures: a study on human specimens.

The aim of this study was to evaluate the diagnostic accuracy of mobile cone beam computed tomography (MCBCT) versus multi-detector computed tomography (MDCT) in orbital floor fractures. Twenty-four fresh cadaver heads were used, and one orbital floor was fractured for each head by transconjunctival approach. MDCT and MCBCT were performed on each of the heads. The images obtained were then analysed independently by eight evaluators. The radiological characteristics of the orbital floor fractures were visualized with good interpretation agreement between the two images. The location of the fracture and enophthalmos were identified in a comparable manner with strong agreement (κ=0.93 and κ=0.85, respectively). Measurements of fatty hernias and bone defects showed a strong correlation between the two imaging modalities (Pearson coefficient between 0.64 and 0.71 and between 0.67 and 0.71, respectively). The fracture limits and the presence of bone fragments, an intrasinus fatty hernia, and a fracture of the associated medial orbital wall were visualized in both examinations with good agreement (κ=0.68, κ=0.51, κ=0.57, and κ=0.46, respectively). The soft tissue study showed superiority for MDCT, with a κ<0.0009. MCBCT showed good diagnostic performance in the study of orbital floor fracture characteristics.

PulseRider Stent-Assisted Coiling of Wide-Neck Bifurcation Aneurysms: Periprocedural Results in an International Series.

The PulseRider is a novel endovascular device specifically designed to treat bifurcation intracranial aneurysms with wide necks. In an international series, we report the results of PulseRider stent-assisted coiling of 15 patients (9 women and 6 men; mean age, 62.6 years) with 15 unruptured wide-neck (median dome size, 8 mm; median neck size, 5 mm) bifurcation aneurysms. Failure of PulseRider treatment occurred in 1 case, and 1 intraprocedural thromboembolic complication was observed. There was no mortality or neurologic permanent morbidity at discharge and at 1 month. Immediate angiographic outcome showed 12 complete occlusions and 2 neck remnants. Follow-up at 6 months was available for 3 aneurysms and demonstrated 2 complete aneurysm occlusions and 1 growing neck remnant. In this small series of selected patients, PulseRider stent-assisted coiling of wide-neck bifurcation aneurysms was feasible with low procedural complication rates. Angiographic follow-up will be required to evaluate the efficacy of the PulseRider device.

pCONus Device for the Endovascular Treatment of Wide-Neck Middle Cerebral Artery Aneurysms.

BACKGROUND AND PURPOSE: Endovascular treatment of bifurcation middle cerebral artery aneurysms with a wide neck could be challenging, and many lesions are still treated by a surgical approach. The pCONus is a newly emerging device for wide-neck bifurcation intracranial aneurysms. To date, a single report on the treatment of intracranial aneurysms including all locations has been published. We report our experience with pCONus in the treatment of wide-neck MCA aneurysms. MATERIALS AND METHODS: MCA aneurysms treated with pCONus in 4 European centers were retrospectively reviewed. RESULTS: Forty MCA aneurysms (mean dome size, 7.7 mm; mean neck size, 5.6 mm) were treated in 40 patients (mean age, 62 years). Aneurysm coiling was performed after deployment of 1 pCONus in 95% (38/40) of cases and after deployment of 2 pCONus devices in 5% (2/40). No procedural angiographic complications were observed. Reversible neurologic complications were noted in 5% (2/40), and permanent neurologic complication, in 2.5% (1/40) at 1 month. There was no mortality. No aneurysms bled or rebled after treatment. Immediate angiographic results were complete aneurysm occlusion in 25% (10/40), neck remnant in 47.5% (19/40), and aneurysm remnant in 27.5% (11/40). Follow-up (mean, 6.8 months) was available for 33 aneurysms (82.5%). Stable or improved results were observed in all except 3 cases, including 48.5% complete occlusions (16/33), 30.3% neck remnants (10/33), and 21.2% aneurysm remnants (7/33). There was no in-stent stenosis or jailed branch occlusion. There was no angiographic recurrence of initially totally occluded aneurysms. CONCLUSIONS: MCA aneurysms with a wide neck are amenable to treatment with pCONus.
