Background: Anterior clinoidal meningiomas are heterogeneous types of lesions that comprise the parasellar lesions group. Due to their close relationship with the optic nerve and internal carotid artery, they become challenging pathologies for neurosurgeons. Case Description: Female 47, presented with superior temporal quadrantanopsia on the right side. Magnetic resonance image revealed type III clinoidal meningioma on the right side. She has undergone a pterional craniotomy for an optic canal unroofing and tumor extraction. Two years of postoperative follow-up the patient underwent a campimetry, which revealed an almost complete visual improvement. Conclusion: To date, the best surgical technique has not yet been defined, so the choice of treatment and surgical technique is based on each case and on the surgeons’ experience.

Purpose: To describe a case of macular telangiectasia type 2 (MacTel) presenting with decreased vision due to intraretinal/sub-internal limiting membrane (ILM) hemorrhage in the absence of neovascularization. Method: Clinical examination and multimodal imaging were performed. Results: A 65-year-old female presented with blurred left vision, recording 20/160 in that eye. There was intraretinal hemorrhage at the left macula centrally, with sub-ILM hemorrhage superiorly and inferiorly. Optical coherence tomography (OCT) showed no evidence of subretinal neovascularization. Imaging of the right macula was consistent with MacTel. The blood spontaneously cleared and the left visual acuity gradually improved to 20/25 by 4 months. Fluorescein angiography confirmed MacTel, and once the hemorrhage resolved, both inner and outer retinal cavitation was identified on OCT of the left macula. The left best-corrected visual acuity remained at 20/25 at 2-year follow-up. Conclusion: Spontaneous resorption of hemorrhage was accompanied by visual improvement.

AIM: The study was conducted to evaluate maximum biting force (MBF) in two different attachment systems (bollard a vs. ball and socket attachment) retaining mandibular overdenture using a split-mouth design. SUBJECTS AND METHODS: Twelve completely edentulous patients received complete dentures and after adaption of the patient with the new denture, 24 implants were inserted in the canine region using two-stage surgical technique and conventional loading protocol. Six patients received the Bollard attachment at the right side and the Ball and Socket at the left side. Moreover, the other six patients received the bollard attachment at the left side and the ball and socket attachment at the right side. Each patient was treated according to split-mouth design. Insertion of each of the attachment type was assigned randomly. Using occlusal force meter instrument, MBF was measured immediately after loading (0), after 6 months (6), and after 12 months (12). RESULTS: Significant statistical differences (p < 0.05) were obvious in in MBF between Attachment (1) and Attachment (2) immediately after loading (0 months), after 6 months (6) and after 12 months (12) follow-up visits. CONCLUSION: Mandibular implant retained overdenture received Bollard abutment that retained with the denture by the help of resilient liner “Retention.sil”* without housing have higher biting forces than mandibular implant retained overdenture with ball abutment where the plastic house was picked up by monomer free self-cured acrylic resin.

ABSTRACT Introduction Ranulas are lesions that affect the salivary glands, and they are generally treated by excision; however, they can recur in some cases where the gland is not removed and they may progress to acute suppurative sialadenitis, yet such cases are rare, especially in children. Aims To report clinical management of occurrence of acute suppurative sialadenitis secondary to excisional biopsy of ranula in a child. Case report An 11-year-old female patient was diagnosed with ranula where excisional biopsy was performed. Subsequently, the patient developed infection, suggesting Ludwig's angina, after reevaluation, she was diagnosed with acute suppurative sialadenitis in the right mandibular gland; during the follow-up period, antibiotic therapy was introduced. Conclusion The close relationship of the biopsy site with the submandibular space and other structures of the neck required the completion of antibacterial prophylaxis associated with preoperative care, transoperative care, and postoperative care to combat opportunistic infections and their subsequent complications. Clinical Significance Suppurative sialadenitis and its subsequent complications may be considered, although rare, as a complication in cases of ranula.

In rare cases a syncope can be caused by compression or irritation of the carotid artery and the carotid sinus due to congenital anatomical anomalies of cervical structures like the hyoid bone. We present the case a of 36 year old man with recurrent syncopes when turning his head. Clinical investigations revealed a hyoid bone anomaly with elongated lesser cornua, especially on the right symptomatic side. Surgical resection of the right lesser cornu led to complete resolution of symptoms over a two year follow-up. Syncope especially in younger subjects may be caused by congenital anomalies of the musculoskeletal system in the cervical region and should be considered in the differential diagnosis of syncope, transient cerebral ischemia and stroke.

Introduction : C‐Guard carotid stent is a self‐expandable open cell stent covered with a double‐layer mesh which was developed for the treatment of internal carotid artery disease. Lower procedural and complications rates, as well as lower post‐operative infarctions are some advantages of this device. Nevertheless, the use of C‐Guard in the treatment of cervical internal carotid artery (ICA) aneurysms is scarce. Therefore, we present two cases in which the C‐Guard stent achieved complete angiographic occlusion at follow‐up. Methods : We identified two cases in which the C‐Guard carotid stent was used to treat symptomatic cervical ICA aneurysms. Angiographic follow‐up was performed. Results : Case 1: 47‐yo female presented left‐sided motor deficit. CT showed ischemic areas in the right hemisphere and CTA demonstrated an unruptured aneurysm in the C1 segment of the right ICA. The patient started dual antiplatelet therapy (DAPT) with aspirin and clopidogrel. A 6mm x 40 mm C‐Guard carotid stent was deployed without complications. One‐year follow‐up CTA showed complete obliteration of the aneurysm with reconstruction of the ICA. Case 2: 38‐yo male presented decreased left visual acuity. CTA and DSA showed an unruptured aneurysm in the C1 segment of the ICA. The patient started DAPT with aspirin and clopidogrel. A 7mm x 30 mm C‐Guard carotid stent was deployed without complications. Three‐month follow‐up DSA showed complete obliteration of the aneurysm with adequate filling of distal vessels. Conclusions : C‐Guard stent is a potential alternative to conventional carotid stents in the treatment of cervical ICA aneurysms with high obliteration rates at follow‐up.

Abstract A 45-year-old woman with known hypothyroidism and no other comorbidities was incidentally found to have multiple right renal artery aneurysms. The largest aneurysm measured 5 x 4.5 cm and arose from an inferior segmental branch while two smaller aneurysms arose from an upper segmental branch of the right renal artery. We performed an ex-vivo repair with reverse saphenous vein graft under cold preservation followed by orthotopic kidney auto-transplantation. Her postoperative course was unremarkable and at 1-year follow-up her right kidney is preserved. In this article, we report successful treatment of complex multiple right renal artery aneurysms and describe the surgical technique used for successful repair.

Context: This case report describes a patient with bilateral dissection of the carotid and vertebral arteries after being immunized by the Astrazeneca vaccine against COVID-19. Case report: AVC, female, 55 years old, health professional, without previous illness, received ChAdOx1 nCov-19 AstraZeneca vaccine and evolved after one day with flu-like symptoms, headache, odynophagia, fever, myalgia for 5 days. On the 7th day, she sought hospital service complaining of sudden headache, and numbness in the left upper limb. A non-reactive Sars-Cov-2 RT-PCR test was performed. The patient was released after clinical improvement. She returned after 8 days, being diagnosed with migraine and was treated with sintomatic drugs. After more 7 days, during the neurologist appointment, she reported daily headaches of varying intensity and episodes of unverified fever, with no findings on physical examination. Laboratory tests, brain resonance with cranial and cervical angioresonance, which showed findings of bilateral carotid dissection, involving the supra-bulbar segments of both internal carotid arteries, notably in the right internal carotid artery, as well as degrees of dissection of both vertebral arteries. On admission, antiplatelet aggregation was chosen, with the patient showing good evolution and being discharged after 4 days for outpatient follow-up. Conclusion: The patient has no evident risk factor for arterial dissection. In addition, the post-vaccine adverse reaction and the temporal gap between the application of the vaccine and the development of multiple arterial dissections drew attention. A possible link between the patient’s immune response and vascular endothelial inflammatory reaction is suggested, resulting in multiple arterial dissections.

Background: Eagle syndrome (ES) is a rare symptomatic condition generally caused by an elongated styloid process (SP) or calcification of the stylohyoid complex. On the diagnosis is made, its treatment remains subjective since the indications for surgical intervention are still not standardized. Although styloidectomy is the surgical treatment of choice, no consensus exists regarding the transcervical or/and transoral route. Here, we report our experience in a patient with bilateral internal carotid artery (ICA) dissection caused by ES, who underwent innovative surgical technique. Case Description: A 53-year-old man, with the right-sided middle cerebral artery acute stroke, underwent computed tomography angiography 3 days after a successful endovascular treatment. The study showed a bilateral ICA dissection with bilateral hypertrophic SPs and a close relationship of ICAs with both SPs anteriorly and C1 transverse process posteriorly. Considering the occurrence of ICA compression by a styloid/C1 transverse process juxtaposition, the patient underwent the left partial C1 transversectomy by an extraoral approach. A temporary paresis of the ipsilateral lower lip lasted 1 month, with a partial remission after 3 months. The patient reported significant improvement of symptoms with a good esthetics and functional outcome. Conclusion: A styloid/C1 transverse process juxtaposition should be considered as an alternative pathogenetic mechanism in vascular ES. When a posterior ICA compression by C1 transverse process is present, a bone reshaping of C1 rather than a conventional styloidectomy can be considered an efficacious treatment which allows a good preservation of the styloid muscles and ligaments.

A 65-year-old woman presented to the emergency department with sudden onset of left-sided weakness, headache and vomiting. A cerebral CT showed an acute intracerebral haemorrhage involving the right caudate nucleus and lentiform nucleus with mild midline shift and intraventricular extension. CT angiography did not reveal aneurysm or other vascular anomaly. Conventional cerebral angiography demonstrated a 3 mm right medial lenticulostriate branch aneurysm, arising from the right anterior cerebral artery (ACA). Endovascular treatment was performed from the left internal carotid via the anterior communicating artery into the right ACA. Complete occlusion was achieved with injection of N-butyl-2-cyanoacrylate. The patient had neurological rehabilitation during hospitalisation followed by outpatient physical therapy. Two years later, clinical follow-up demonstrated excellent recovery.
