Abstract	Arteriovenous malformations (AVMs) are vascular malformations that present high-flow direct communication between the arteries and veins, not involving the capillary beds. They can be progressive and lead to various manifestations, including abnormal skin or mucosal findings, ischemia, hemorrhage, and high-output heart failure in severe cases. AVMs often involve the head and neck region. Head and neck AVMs can present region-specific clinical manifestations, angioarchitecture, and complications, especially in cosmetic appearance and ingestion, respiratory, and neuronal functions. Therefore, when planning endovascular treatment of head and neck AVMs, physicians should consider not only the treatment strategy but also the preservation of the cosmetic appearance and critical functions. Knowledge of the functional vascular anatomy as well as treatment techniques should facilitate a successful management. This review summarizes AVMs' clinical manifestations, imaging findings, treatment strategy, and complications.

Abstract	Purpose: To assess the feasibility of transarterial embolization (TAE) for recalcitrant nighttime shoulder pain in a multicentric study. Materials and methods: This prospective, open-label, feasibility trial included 100 patients treated at 5 institutions. TAE was performed in 76 patients with adhesive capsulitis (AC) and 24 patients with symptomatic rotator cuff tears (sRCTs). The ipsilateral radial artery was punctured, and imipenem/cilastatin sodium was infused as an embolic agent. Adverse events, 10 point pain numerical rating scale (NRS), range of motion (ROM) of the shoulder joint, and quality of life (via the EuroQol-5D [EQ-5D]) were evaluated. Results: All patients exhibited neovascularity on baseline angiography, and all TAE procedures were performed successfully. No patient experienced a major adverse event. The mean nighttime pain NRS scores at baseline and 1, 3, and 6 months after TAE were 6.4 ± 2.2, 3.4 ± 2.6, 2.3 ± 2.5, and 1.6 ± 2.2, respectively (for all, P < .001). The mean ROM of anterior elevation at baseline and 1, 3, and 6 months after TAE were 97° ± 29°, 119° ± 28°, 135° ± 27°, and 151° ± 17°, respectively (for all, P < .001). The mean EQ-5D scores at baseline and 1, 3, and 6 months after TAE were 0.63 ± 0.17, 0.73 ± 0.16, 0.80 ± 0.17, and 0.84 ± 0.17, respectively (for all, P < .001). There was no significant difference in the clinical success rate between the AC and sRCT groups. Conclusions: TAE for nighttime shoulder pain caused by AC and sRCTs was feasible with sufficient safety and efficacy.

Abstract	Purpose: This study aimed to evaluate the value of fat-suppressed T2-weighted imaging (FS-T2WI) for predicting short-term pain relief after polidocanol sclerotherapy for painful venous malformations (VMs) in the extremities. Materials and methods: This retrospective study included patients with painful VMs in the extremities between October 2014 and September 2021, had their first sclerotherapy without history of surgical therapy, and underwent magnetic resonance imaging before sclerotherapy. Pain relief was assessed 2 months after 3% polidocanol sclerotherapy and was categorized as follows: progression, no change, partial relief, or free of pain. The associations between pain relief and imaging features on FS-T2WI were analyzed. Results: The study included 51 patients. The no change, partial relief, and free of pain groups included 6 (11.8%), 25 (49.0%), and 20 (39.2%) patients, respectively. No patient experienced progressive pain. The lesion diameter was ≤ 50 mm in 13 (65.0%) patients in the free of pain group, whereas it was > 50 mm in all patients in the no change group (p = 0.019). The lesions showed well-defined margin in 15 (75.0%) patients in the free of pain group, whereas they showed ill-defined margin in 5 (83.3%) patients in the no change group (p = 0.034). The most common morphological type was cavitary in the free of pain group (14 [70.0%] patients), whereas there was no patient with cavitary type lesion in the no change group (p = 0.003). Drainage vein was demonstrated in 6 (100%), 22 (88.0%), and 11 (55.0%) patients in the no change, partial relief, and free of pain group, respectively (p = 0.011). Conclusion: A lesion size of 50 mm or less, a well-defined margin, a cavitary type, and no drainage vein on FS-T2WI were significant features for predicting short-term pain relief after polidocanol sclerotherapy for painful VMs in the extremities.

Abstract	BACKGROUND Tumor-induced osteomalacia (TIO) is a paraneoplastic syndrome caused by aberrant fibroblast growth factor-23 (FGF-23)-producing tumors. Early surgical resection is the optimal strategy for preventing TIO progression. Thus, tumor localization is a priority for successful treatment. A simple and safe examination method to identify functional endocrine tumors is essential to achieve better outcomes in patients with TIO. CASE REPORT A 64-year-old Japanese man with recurrent fractures, hypophosphatemia, and elevated alkaline phosphatase and FGF-23 levels (109 pg/mL) was admitted to our university hospital and was diagnosed with FGF23-related hypophosphatemic osteomalacia. Notably, the superficial dorsal vein in the patient's left foot exhibited a high FGF-23 level (7510 pg/mL). Octreotide and ¹⁸F-fluorodeoxyglucose (FDG) scintigraphy and systemic venous sampling revealed that the tumor in the third basal phalanx of the left foot was responsible for FGF-23 overproduction. Tumor resection resulted in a rapid decrease in serum FGF-23 levels and an increase in serum phosphorus levels. CONCLUSIONS Octreotide scintigraphy, FDG-positron emission tomography, and systemic venous sampling are the standard methods for localizing functional endocrine tumors. However, the limited availability and invasive nature of these examinations hinder effective treatment. Here, we highlight the importance of peripheral superficial blood sampling as an alternative to conventional systemic methods for confirming the presence of FGF-23-producing tumors. Clinicians should consider TIO as a potential cause of acquired hypophosphatemic osteomalacia. Furthermore, peripheral superficial vein blood sampling may be useful for confirming the localization of FGF-23-producing tumors.

Abstract	Background: Treating arteriovenous malformation (AVM) is challenging because of the high recurrence rate and because incomplete resection or embolization can induce aggressive growth. However, a standard strategy is not fully established. Although transcatheter arterial embolization (TAE) is currently almost always part of the treatment, in many cases, single treatment is not curative and only palliative. Additionally, the success and complication rates associated with TAE alone are unclear, and there has been limited study of staged TAE for facial AVMs. Furthermore, few reports have described the details of the procedure. Case-presentation: We report two cases of AVM of the upper lip in patients who were successfully treated by staged super-selective TAE at several-month intervals using ultra-thin microcatheters and n-butyl-2-cyanoacrylate. Conclusion: Staged and super-selective TAE may prevent complications and provide high curability and might be a useful treatment in cases of AVM.

Abstract	Subclavian artery dissecting aneurysm is relatively rare and can be caused by traumatic, nontraumatic, and iatrogenic etiologies. Surgical management of subclavian artery dissecting aneurysm has been sparsely reported. Recently, due advances in endovascular techniques making them less invasive, these approaches have become more standard as treatments. Subclavian artery dissecting aneurysm management usually depends on whether there is ischemia of the tissues supplied by the subclavian artery. Furthermore, treatment strategies depend on which section of the artery is involved. In particular, treatment is difficult if the dissecting aneurysm has branching vessels. In this case report, we show that endovascular repair using a covered stent graft is a promising approach to repair a subclavian artery dissecting aneurysm. In this case, the stent graft was highly effective, and follow-up examinations showed good patency of the subclavian artery. Additional use of IVUS (Volcano Inc.; Rancho Cordova, CA, USA) is helpful to obtain the precise location of the true lumen of a dissecting aneurysm.

Abstract	The Amplatzer vascular plugs (AVPs), including AVP 4, have excellent occlusion; however, insufficient embolization or recanalization may occasionally occur. This study aimed to evaluate the feasibility and effectiveness of internal coil packing method to insert microcoils into the AVP 4 using an experimental vascular model. The insertion of a 1.7 F microcatheter through the nitinol mesh of the AVP 4 was not possible. Only 0.010-inch electrolytic detachable microcoils could be inserted through catheter tips in contact with nitinol mesh. The internal coil packing of the AVP 4 may be accomplished by inserting 0.010-inch microcoils into the AVP 4 in cases of continued perfusion or recanalization with required short-segment embolization.
