This study aimed to compare radiographic outcomes of adult spinal deformity (ASD) surgery with or without 2-level prophylactic vertebroplasty (PVP) at the uppermost instrumented vertebra (UIV) and the vertebra 1 level proximal to the UIV. ⋯ PVP at UIV and vertebra 1 level proximal to the UIV cannot prevent PJK, PJF, and PJFX; however, it plays a positive role by delaying their progression. Furthermore, PVP tends to lower the reoperation rate after PJFX in ASD surgery.

Although pituitary adenoma (PA) and Rathke cleft cyst (RCC) share a common embryologic origin, concurrent appearances have rarely been reported. We present a case of intractable RCC hidden behind a coexisting giant PA. ⋯ The presence of a nonenhanced cyst with a PA on magnetic resonance imaging suggests the possibility of coexisting RCC and PA.

Ligaments of the craniocervical junction play a critical role in stabilizing this region. Gerber's ligament has more or less been forgotten and, to our knowledge, never studied. ⋯ A good understanding of all ligaments of the craniocervical junction is important to surgeons and physicians treating patients with injury to the upper cervical spine.

Transseptal puncture has been widely used by cardiologists to reach the left side of the heart through a transvenous access. Rarely, it also can be used to pass into the supra-aortic arteries from the venous side when conventional transarterial access pathways (transfemoral, transradial/brachial routes, or direct carotid puncture) are likely to fail. ⋯ Transvenous-transseptal access enabled treatment of both cases easily and without complications. On follow-up computed tomography angiograms, both flow diverters were patent, there were no residual aneurysms, and no neurologic or cardiac adverse events in either patient.
