Thoracic kyphosis can result in neurologic deficits, pain, and cardiopulmonary dysfunction. Vertebral column resection (VCR) is a powerful technique that can be employed for large curves and fixed deformities. This study reports the outcomes of posterior VCR for adult spinal deformity with severe thoracic kyphosis. ⋯ Single-stage posterior VCR is a powerful technique for the correction of severe thoracic kyphosis. Perioperative morbidity can be high, but a majority of patients fare well at follow-up. Junctional disease occurs both proximal and distal; surgeons should continue to implement strategies to minimize distal junctional disease.

The present study introduced ultrasound volume navigation (UVN) to reduce the radiation exposure and puncture time of percutaneous transpedicular puncture in percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP). ⋯ UVN could obviously reduce the radiation exposure and puncture time of percutaneous transpedicular puncture in PVP and PKP.

Ophthalmic trunk aneurysms associated with other vascular malformations are extremely rare, and little is known regarding its natural history and options of treatment. ⋯ A follow-up angiogram at 6 months showed complete obliteration of the dural arteriovenous fistula and regression of the ophthalmic trunk aneurysm. The literature is reviewed, and potential pathophysiologic mechanisms leading to this association and regression in this subgroup of aneurysms are discussed.

Blood blister-like aneurysms (BBAs) are an uncommon group of arterial aneurysms with a high risk of rupture, progression, and repeat rupture. The best intervention is unclear; however, their clinical behavior typically requires urgent intervention. We describe a BBA managed conservatively with complete resolution found at follow-up. ⋯ DSA remains an important imaging study for the detection of small aneurysms, because CT angiography might not have sufficient resolution. Our unique case provides strong evidence that BBAs represent a parent artery focal dissection. BBAs can remodel over time, usually with enlargement and repeat rupture if untreated. It is possible, as we have demonstrated, that some small lesions presenting with SAH might spontaneously heal without intervention.

Rupture of a Giant Anterior Sacral Meningocele in a Patient with Marfan Syndrome: Diagnosis and Management.
Marfan syndrome is a genetic disorder that results in the weakening of connective tissues. Dural ectasia has been defined as a feature of Marfan syndrome and is present in up to 92% of patients. Rarely, dural ectasia can erode through the sacrum expanding into an anterior sacral meningocele. ⋯ The progression of dural ectasia in Marfan syndrome to an anterior sacral meningocele is uncommon. It is important to identify the characteristics associated with an expanding dural ectasia as this patient's symptoms progressed over time and the meningocele grew large. Given its rarity, there are no guidelines in place regarding size at which repair of an anterior sacral meningocele should occur prophylactically. It is important to review these cases in order continue to learn about progression, management, and outcomes of patients with an anterior sacral meningocele.
