Multi-vessel cervical arterial injury after blunt trauma is rare, and its pathophysiology is unclear. Although blunt cerebrovascular injury is a common cause of cerebral ischemia, its management is still controversial. We describe a 23-year-old man in previously good health who developed three-vessel cervical arterial dissections due to blunt trauma. He was admitted to our emergency and critical care center after a motor vehicle crash. Computed tomography showed a thin, acute subdural hematoma in the right hemisphere and fractures of the odontoid process (Anderson type III), pelvis, and extremities. He was treated conservatively, and about 1 month later, he developed bleariness. Computed tomography angiography showed bilateral internal carotid and left vertebral artery dissection. Aspirin therapy was started immediately, and then clopidogrel was added to the regimen. Two weeks later, magnetic resonance angiography (MRA) showed improved blood flow of the vessels. Only aspirin therapy was continued. About 3 months after discharge, MRA demonstrated further improvement of the blood flow of both internal carotid arteries, but the dissection flap on the right side remained. Therefore, we extended the duration of antiplatelet therapy. On the basis of our experience with this case, we think that antithrombotic therapy is crucial for the management of multi-vessel cervical arterial injury, and agents should be used properly according to the injury grade and phase; however, further study is needed to confirm this recommendation.
This study investigated the long-term outcomes of patients with World Federation of Neurosurgical Societies (WFNS) grade V aneurysmal subarachnoid hemorrhage (SAH) who underwent early aneurysm repair. We evaluated consecutive patients with WFNS grade V aneurysmal SAH from April 2010 to March 2015 who underwent aneurysm repair within 72 h after onset. We assessed the functional outcomes at discharge and 3 years after onset using the modified Rankin Scale (mRS). The primary outcome was defined as a favorable functional outcome (mRS ≤2). We identified 145 patients with grade V SAH during the study period. Of these, 44 patients (19 males and 25 females; median age, 64 years; range, 24–79 years) met the inclusion criteria. For aneurysm repair, surgical clipping and coiling were performed in 40 (90.9%) and 4 (9.1%) patients, respectively. Although no patient had a favorable functional outcome at discharge, 11 (25.0%) patients had a favorable functional outcome at the end of follow-up. The number of patients with a favorable outcome significantly increased during the first year (
P
= 0.012) and during the follow-up period (
P
<0.001). Patients who underwent active rehabilitation had significant improvement. Our study showed that one-fourth of the patients who underwent early aneurysm repair with WFNS grade V SAH achieved a mRS score of ≤2 over a 3-year period. It might be important to consider age and rehabilitation for better clinical outcomes. Larger studies are required to adequately assess the long-term functional outcomes and other multi-faceted prognoses.
We report a case where a dural arteriovenous fistula (DAVF) was treated successfully with single-stage surgically assisted transcranial transvenous embolization. For this purpose, direct puncture of the transverse sinus was made with the patient in the prone position.Case Presentation: A 78-year-old female presented with pulsatile tinnitus and ataxia. Cerebral angiography confirmed the presence of a left transverse-sigmoid sinus DAVF with retrograde cortical venous reflux. As transvenous approach via the femoral vein was not possible, transcranial approach with direct puncture of transverse sinus was used for embolization of the fistula in the prone position with Prone View. Angiography demonstrated complete occlusion.Conclusion: Direct puncture of transverse sinus with Prone View may be considered a safe and effective approach when other approaches are not feasible.
