Review Case Reports
Temporary vertebral artery occlusion after C3 fracture dislocation injury and spontaneous resolution following reduction and instrumented fusion: case report and literature review.
Vertebral artery injuries as a result of blunt trauma can result in vertebrobasilar strokes. Typical treatment of such an injury includes early anticoagulation to prevent cerebral ischemic events due to vessel occlusion or embolism. ⋯ Postoperative cerebral angiography showed no evidence of vertebral artery stenosis, and systemic anticoagulation was discontinued. This case shows that vertebral artery occlusion can resolve spontaneously after fracture reduction, and cerebral angiography should play a role in assessing these complicated traumatic injuries.

Venous outflow obstruction has been implicated in the pathophysiology of a subset of patients with idiopathic intracranial hypertension (IIH), and venous sinus stenting (VSS) has emerged as an effective treatment. However, the effect of anesthesia on venous sinus pressure measurements is unpredictable. A more thorough understanding of the effect of the level of anesthesia on intracranial venous pressures might help to better define patients who might benefit most from stent placement. ⋯ Intracranial venous pressures are markedly affected by GA. In order to obtain an accurate measurement of MVPs and trans-stenosis gradients, patients undergoing investigation for IIH should undergo cerebral angiography and venous manometry under CS, which provides more reliable data for outcomes after VSS.

Intracranial blood blister-like aneurysm (BBA) is a rare type of aneurysm that lacks all layers of the arterial wall. These fragile aneurysms have the propensity to rupture with minimal manipulation, which makes them hazardous and difficult to treat. The present study evaluated the safety and feasibility of endovascular treatment of BBAs with the Willis covered stent. ⋯ Willis covered stent implementation may be safe and feasible for BBAs. This strategy might be a promising option for this high-risk type of aneurysm.
