Background and Importance: The use of flow-diverting stents has gained acceptance during the past few years for the treatment of numerous intracranial aneurysms, especially large or giant ones. However, successful catheterization of the distal parent artery in giant intracranial aneurysms with a microcatheter can be extremely challenging. Forming a microcatheter loop in the aneurysm sac can aid distal catheterization.
Clinical Presentation: We report the use of a Solitaire FR stent as an adjunctive tool in the successful treatment of two giant intracranial unruptured aneurysms with Pipeline Embolization Devices (PEDs). After having formed a loop inside the aneurysm sac, the microcatheter was anchored distally by a Solitaire FR stent. With the Solitaire FR device opened, the loop in the giant aneurysm sac was completely reduced without loss of the microcatheter position in the distal parent artery. A PED could be delivered in both cases without any difficulty. No complications occurred.
Traumatic injuries of the craniovertebral junction (CVJ) area are common and frequently the outcome of motor vehicle accidents, falls, and diving accidents. To define and characterize CVJ traumatic injuries, some international classifications are currently in use, and they are thought and focused on junction bone fracture. However, recent data point out a major important role of the CVJ ligaments and membranes in traumatic injuries with a secondary function of the osseous structures. Emphasizing the correct role of the ligaments and membranes is extremely important for determining appropriate medical or surgical planning for patients and also to design new CVJ injury classifications.

BACKGROUND: Knowledge of the anatomy of ligaments that bind the craniocervical junction is important for treating patients with lesions of this region. Although the anatomy and function of these ligaments have been well described, those of the transverse occipital ligament (TOL) have remained enigmatic.
OBJECTIVE: To describe the anatomy and functions of the transverse occipital ligament.
METHODS: Via a posterior approach, 9 cadaveric specimens underwent dissection of the craniocervical junction with special attention to the presence and anatomy of the TOL.
