Juvenile angiofibroma is a rare benign expansive lesion typically affecting young men. Surgery is the current mainstay of treatment. Because it is a very vascular lesion, preoperative transarterial embolization can decrease intraoperative bleeding.1,2 Transmaxillary or transpalatal approaches were used for totally extracranial lesions. Endonasal endoscopic resection became wildly used for radical excision with limited morbidity.2 In large lesions with intracranial extension and cavernous sinus involvement (Fisch type 4), purely anterior approaches (endoscopic or transmaxillary) can be associated with significant carotid artery and cranial nerves injuries and excessive hemorrhage from internal carotid artery supply that cannot be eliminated by preoperative embolization.3 Subtotal resection has been preconized in such cases, but tumor progression, cranial nerves and vision compromise, and major nasal postoperative bleeding could ensue. Radiotherapy of residual tumor has been associated with long-term complications, particularly given the young age of these patients.2 The cranio-orbital zygomatic approach provides an excellent exposure to the extensions into the middle fossa, anterior fossa, cavernous sinus, paranasal sinus, and infratemporal fossa components of large angiofibromas.4-6 It is particularly advantageous in the early interruption of the cavernous carotid feeders that are not amenable to safe embolization, rendering the tumor devascularized and bloodlessly resected. This article demonstrates the details and the advantages of this approach in a 13-year-old adolescent boy operated in 1997 for giant juvenile angiofibroma with extension in the middle fossa and the parasellar space with major vascularization from the cavernous carotid artery.

JIB-04, a histone demethylase Jumonji C domain inhibitor, regulates phenotypic switching of vascular smooth muscle cells.

Authors:
Yi He Xin Yi Zihao Zhang Hanshen Luo Rui Li Xin Feng Ze-Min Fang Xue-Hai Zhu Wenlin Cheng Ding-Sheng Jiang Fang Zhao Xiang Wei

Clin Epigenetics 2022 Aug 13;14(1):101. Epub 2022 Aug 13.

Division of Cardiothoracic and Vascular Surgery, Sino-Swiss Heart-Lung Transplantation Institute, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, 1095 Jiefang Ave, Wuhan, 430030, Hubei, China.

Background: Vascular smooth muscle cell (VSMC) phenotype switching is critical for neointima formation, which is the major cause of restenosis after stenting or coronary artery bypass grafting. However, the epigenetic mechanisms regulating phenotype switching of VSMCs, especially histone methylation, are not well understood. As a main component of histone lysine demethylases, Jumonji demethylases might be involved in VSMC phenotype switching and neointima formation. Read More

Department of Interventional Radiology, Affiliated Hospital 2 of Nantong University, Nantong, China. Electronic address:

Objective: To investigate the correlation between annular plaque calcification in the carotid sinus and perioperative hemodynamic disorder (HD) in carotid angioplasty and stenting (CAS).

Methods: The clinical data of 49 patients undergoing CAS due to narrowing of the carotid sinus were retrospectively analyzed. All patients had preoperative carotid computed tomography angiography (CTA) and were divided into HD and non-HD groups based on the occurrence of HD in the perioperative period of CAS. Read More
