1. Three Different Strategies for Repair of Symptomatic or Aneurysmatic Aberrant Right Subclavian Arteries
ABSTRACT Introduction: In this study, we aimed to present three different methods for symptomatic aberrant right subclavian artery (ARSA) surgery. Methods: We identified 11 consecutive adult patients undergoing symptomatic and/or aneurysmal ARSA repair between January 2016 and December 2020. Symptoms were dysphagia (n=8) and dyspnea + dysphagia (n=3). Six

2. Physical exercise prevents motor disorders and striatal oxidative imbalance after cerebral ischemia-reperfusion
Stroke is the third most common cause of death worldwide, and most stroke survivors present some functional impairment. We assessed the striatal oxidative balance and motor alterations resulting from stroke in a rat model to investigate the neuroprotective role of physical exercise. Forty male Wistar rats were assigned to 4 groups: a) control, b) ischemia, c

3. Can contrast-enhanced ultrasound with second-generation contrast agents replace computed tomography angiography for distinguishing between occlusion and pseudo-occlusion of the internal carotid artery?
OBJECTIVE: The purpose of this study was to evaluate the effectiveness of contrast-enhanced ultrasound with a second-generation contrast agent in distinguishing between occlusion and pseudo-occlusion of the cervical internal carotid artery, comparing it with that of conventional Doppler ultrasound and the gold standard, computed tomography angiography. METH

4. Detecção de bactérias periodontopatogênicas cultiváveis e não cultiváveis em placas ateromatosas
Periodontal infections consist of a group of inflammatory conditions caused by microorganisms that colonize the tooth surface through the formation of dental biofilm. Chronic infections such as periodontitis have been associated to the development and progression of atherosclerosis. AIM: Detect cultivatable and non-cultivatable periodontopathogenic bacteria

5. Complexo miointimal das carÃtidas comum e interna de portadores de esquistossomose mansÃnica hepatoesplÃnica: avaliaÃÃo com eco-Doppler colorido
The aim of this study was to evaluate the intima-media thickness (IMT) of common and internal carotid arteries in a group of patients with hepatosplenic schistomiasis mansoni and other group who underwent portal decompression surgery (splenectomy and left gastric artery ligature). Both groups were compared with a health volunteer control group, living in the

6. Sutura mínima associada ao adesivo de fibrina em microanastomoses arteriais: estudo experimental comparativo com a técnica de sutura convencional / Minimal suture associated with fibrin adhesive in microvascular arterial anastomosis: comparative experimental study with the conventional suture technique
Mastering of the microvascular anastomosis technique is an essencial requirement to perform reconstructive microsurgical procedures, such as replantation surgery and free tissue transfers. Until now, the conventional suture technique is the most widely accepted in the clinical setting, for its safety and versatility. However, this technique presents some pro

7. L-deprenil previne alterações neuroquímicas e comportamentais induzidas pela isquemia cerebral transitória / L-Deprenyl prevines neurochemicals and comportamentals alterations induced of transiente cerebral ischaemia
The present work shows the effects of l-deprenyl (DEP, 5 and 10 mg/kg, po) on memory, as well as on rat brain free radical formation after transient cerebral ischemia (TCI). Wistar rats were anesthetized and submitted to TCI by occlusion of both carotid arteries for 20 minutes. In another experiment, animals were submitted to surgery without ischemia (sham-o

8. Trombose carotídea após traumatismo contuso
The authors report a case of thrombosis of common and internal carotid arteries caused by blunt trauma. They emphasize the rarity of this lesion and the variability of clinical presentation. Different forms of treatment are analysed, such as the use of anticoagulation and surgery. Treatment needs to be individualized for each patient.

9. Bilateral carotid endarterectomy combined with myocardial revascularization during the same surgical act
The best surgical approach for the treatment of patients with severe cerebral artery disease and simultaneous serious coronary artery disease still remains controversial. In this report we present a case of a 72-year-old female patient admitted to the hospital with unstable angina. Triple coronary artery obstructive disease and severe bilateral carotid arter

10. Recurrent carotid artery stenosis following endarterectomy.
Spectral analysis was used to examine 257 carotid arteries in 227 patients who had undergone carotid endarterectomy at 1, 3, 6, and 12 months after surgery and annually thereafter. Routine intraoperative completion angiography ensured that the operations were technically satisfactory. Postoperative restenoses were identified in 38 patients (15%). In 23 arter

11. Complications of cerebral angiography in patients with symptomatic carotid territory ischaemia screened by carotid ultrasound.
After nearly 40 years, carotid endarterectomy has been shown to be of benefit to patients with symptomatic carotid territory ischaemia and greater than 70% stenosis of the relevant internal carotid artery. Cerebral angiography is performed before surgery and is not without risk. These risks must be added to those of surgery before recommending the procedure

12. Use of Absorbable Sutures in Canine Carotid Arteries
To study the functional and microstructural characteristics of polydioxanone sutures in vascular surgery, we created 48 vascular anastomoses in the right and left common carotid arteries of 24 mongrel dogs. In each animal, polydioxanone sutures were used in 1 carotid artery, and polypropylene sutures were used in the contralateral carotid artery. Twelve grou
