Introduction and Importance: Cervical paragangliomas of the vagus nerve are tumors, of wich the nature and location make them extremely rare, representing only 0.012 % of cervical tumors., Case Presentation: This article reports the case of a 64 year old patient, consulting for a latero-cervical mass associated with dysphonia, dysphagia, and repeated vagal syncopes, evolving for 10 months. The patient underwent surgical resection of the tumor and the carotid artery, with reconstruction by common carotid to internal carotid Polytetrafluoroethylene (PTFE) graft bypass. The patient recovered with no major postoperative complication., Clinical Discussion: Cervical paragangliomas of the vagus nerve present clinically as a slow-growing latero-cervical mass that damages the cranial pairs, manifesting by dysphonia, dysphagia, vagal syncope and hypertensive peaks. Imaging is a major step in the diagnosis, allowing better planning of the surgical procedure. Magnetic Resonance Imaging (MRI) is considered to be the benchmark imaging for the characterization of the tumor, but Computerised Tomography (CT) Scan, CT angiography and Doppler ultrasonography of Supra-aortic trunks keep an important place in the search of associated vascular lesions. Surgery remains the only curative treatment, but it faces many obstacles, including the difficulty of dissection of the cranial pairs and adjacent vascular structures (especially the carotid artery). The postoperative morbidity is heavy with difficult recovery. The place of radiotherapy is controversial., Conclusion: Paragangliomas of the vagus in the cervical region are rare tumors, of which the localization is even rarer. Surgical excision remains the only curative treatment. Palliative radiotherapy may be considered for some patients., Competing Interests: Declaration of competing interest The authors report no declarations of interest., (Copyright © 2024.

Brachial artery aneurysmal degeneration is an exceptional complication of distal native fistulas. Chronic mechanical stresses due to high flow, as well as immunosuppressants drugs following renal transplantation, are the mains factors implicated in the pathophysiological mechanism. We report a case of a transplant patient with a true, symptomatic, brachial artery aneurysm, 8 years after transplantation and 5 years after radiocephalic wrist fistula ligation. The patient underwent open surgical repair, with aneurysm resection and end-to-end anastomosis. We present a literature review of the different therapeutic strategies of this unusual entity., (Copyright © 2021. Published by Elsevier Masson SAS.)

The creation and preservation of vascular accesses, in patients with end-stage renal failure, remains a challenge for nephrologists and vascular surgeons. Native fistula is the best vascular access, humeral-basilic fistula is a precious access in patients who have exhausted their venous capital in the forearm and in whom the cephalic vein of the arm is small or damaged. Given its deep location, any puncture of this vein is prohibited before its superficialization, even if it is of good caliber, because it can have dramatic consequences, in particular the loss of the limb or even death. We report the case of a patient undergoing hemodialysis for seven years with a non-superficialized humeral-basilic fistula, admitted for an iatrogenic false aneurysm of the brachial artery following a puncture for dialysis, with compression of the median nerve, treated surgically., (Copyright © 2021 Société francophone de néphrologie, dialyse et transplantation.
