Impact of 68Ga-DOTATOC PET/MRI on robotic radiosurgery treatment planning in meningioma patients: first experiences in a single institution

Güliz Acker, Anne Kluge, Mathias Lukas, Alfredo Conti, Diana Pasemann, Franziska Meinert, Phuong Thuy Anh Nguyen, Claudius Jelgersma, Franziska Loebel, Volker Budach, Peter Vajkoczy, Christian Furth, Alexander D. J. Baur, and Carolin Senger

. We observed no acute toxicity related to the treatment within the 1st month after the therapy. The mean follow-up time was 4.5 ± 3.8 months. Within the follow-up period, 1 patient with a sphenoorbital lesion reported suffering from a mild temporary trigeminal neuralgia, although her vision improved after therapy. No further complications were recorded that might be related to a planning error. Comparison of Planned Target Volumes The RS0-PTV and RS1-PTV did not differ significantly (mean difference 0.31 ± 1.31 cm 3 ; Fig. 1A ). The RS1-PTV was smaller than the RS0

approved for PD in 2002. As the number of DBS cases has increased over the years, so have the clinical indications. DBS is now used to treat dystonia, essential tremor, obsessive-compulsive disorder, Tourette’s syndrome, epilepsy, cluster headaches, stroke-related pain, phantom-limb pain, trigeminal neuralgia, and multiple sclerosis. 4 , 21 , 29 , 35 When DBS gained government-regulated approval, an increase in the national number of DBS procedures was noted. In 1996, 756 DBS procedures were performed, which increased to 4200 DBS procedures by 2006. 25 As DBS

Anatomical connections of the SPG. c.n. = cranial nerve. To date, there are no widely shared protocols available for PCP treatment that are based on high-quality, evidence-based data. 2 A complete review of the state-of-the-art prevention and treatment of PCP is beyond the scope of this paper; however, some successful treatments that have been reported are pregabalin, 5 electroacupuncture, 6 anesthetic scalp

Introduction. Surgery involving the venous system and complication avoidance

, interventionalists, and others. With improved microsurgical instruments and techniques and more sophisticated means of assessing venous anatomy, a greater understanding of the significance of cerebral veins is developing. Adding to this understanding is the present issue of Neurosurgical Focus , which includes 11 articles discussing surgeries that involve the venous system and the avoidance of venous complications. Toda et al. describe a series of 121 patients with trigeminal neuralgia and 205 patients with hemifacial spasm, finding that venous compression portended a worse

not even be considered if the superior petrosal sinus is dominant or the Labbé complex in intratentorial. The distinction between pathological states and physiological states is critical: sacrificing a petrosal vein in the setting of a petroclival meningioma is clearly more consequential than doing this in the setting of a microvascular decompression for trigeminal neuralgia, where none of the other veins are compromised. And lastly, it is often forgotten that a vein may look, at first glance, impossible to spare during initial dissection, and yet it is remarkable
