ABSTRACT
This study aimed to identify factors that predict complications following cranioplasty, by conducting a retrospective cohort study at a large tertiary care center. Electronic databases were searched to identify all patients who underwent cranioplasty at our institution. Baseline demographics, perioperative variables, and outcomes were extracted. Logistic regression analyses were conducted to identify factors associated with cranioplasty complications. Of the 92 included patients, 15 (16.3%) experienced one or more complications, with 11 (73.3%) experiencing complication within 30 days of cranioplasty. Patients aged ≤60 had decreased odds of all-cause complication (OR 0.058; 95% CI 0.008-0.434) and cranioplasty graft removal (OR 0.035; 95% CI 0.004-0.321) on multivariate analysis. Titanium mesh cranioplasties were associated with increased odds of all-cause complication (OR 19.776; 95% CI 1.021-382.901), and cranioplasty removal (OR 29.780; 95% CI 1.330-666.878). A longer craniectomy-cranioplasty interval was associated with increased odds of cranioplasty removal (OR 1.005; 95% CI 1.000-1.010). An initial craniectomy indication of cerebral infarction was associated with decreased odds of all-cause complication (OR 0.042; 95% CI 0.002-0.876) and cranioplasty removal (OR 0.032; 95% CI 0.001-0.766). Elderly patients may require more aggressive follow-up and antibiotic prophylaxis in the postoperative period following cranioplasty. Additionally, avoiding the use of titanium mesh cranioplasties and prolonged craniectomy-cranioplasty intervals may further reduce complications.

BACKGROUND: Intracavernous aneurysms constitute up to 9% of all intracranial aneurysms and 6% are infectious (IIA). First line therapy is a protracted antibiotic course, yet with failure, surgery and endovascular parent vessel sacrifice have been utilized. Reconstructive endovascular therapies have emerged for aneurysm control and may demonstrate a safer therapeutic alternative. OBJECTIVE: To present an IIA treated with a flow-diverting Pipeline stent (ev3 Neurovascular, Irvine, California). METHODS: A 41-yr-old female presented with visual loss, ophthalmoplegia, and cavernous sinus thrombosis with an associated phlegmon. Transsphenoidal evacuation was performed without complication or bleeding and she continued on medical therapy. Two weeks postoperatively, she developed a worsening right third cranial nerve palsy and MRA demonstrated a 1-cm right IIA, not evident on postoperative MRI. Three days of dual antiplatelet therapy preceded successful pipeline embolization. Angiography demonstrated aneurysm obliteration at 3 mo and her right ophthalmoplegia resolved. RESULTS: A literature review identified 6 reported cases of IIAs treated with stent embolization. Only 1 documented a flow-diverting Silk stent used in a child. All lesions were obliterated at follow-up without neurological sequelae. No complication arose with implantation in the setting of infection, and as few as 3 d of dual antiplatelet therapy was sufficient for preprocedural prophylaxis, although in Vivo antiplatelet activity may be more significant. CONCLUSION: We report the first case of an IIA treated with a flow-diverting pipeline stent. These devices preserve native vasculature and neurological function compared to surgical and endovascular vessel sacrifice strategies. They appear to be safe management options for the treatment of IIAs.

The Yale Medical Orchestra displayed exceptional talent and inspiration as it performed a timeless composition to celebrate Yale School of Medicine's bicentennial anniversary during a December 2010 concert. Under the leadership of musical directors Robert Smith and Adrian Slywotzky, the richly emotional meditations of Mendelssohn, Dvorak, Schubert, and Yale's own Thomas C. Duffy filled the minds and hearts of an audience as diverse as the orchestra. I intend to retrace the steps of that melodic journey in this essay, fully aware of the limits imposed on me to recreate the aural art form through the medium of text. While these symbols can be pale representations of the beauty and complexity of the music, I hope they will be the building blocks for the emotional experience of the audience. I describe the works' inception and their salient musical features and then review what we know about the effects of melody, meter, and timbre on our brains. My intentions are to provide evidence to encourage the further use of music as a tool in medical practice, provide interest in the works explored by the Yale orchestra, support the orchestra itself, and investigate a personal passion.
