Endovascular Stent Implantation in the Treatment of Vertebrobasilar Dolichoectasia.

Vertebrobasilar dolichoectasia (VBD) is a rare disease in clinic, with an incidence of 0.06% and 5.8%. It is a progressive vascular disease caused by the dilatation, tortuosity, and prolongation of vertebral and basilar arteries caused by a variety of factors. VBD can lead to hemodynamic changes, ischemic stroke, compression symptoms due to vasodilation, neurological dysfunction, hydrocephalus, subarachnoid hemorrhage, and other clinical manifestations. However, because the condition of VBD is complex and changeable, the treatment of VBD is not uniform. With the development of vascular intervention, especially the development of stent technology, it may become an effective method for the treatment of VBD. Two patients with VBD were treated with endovascular stent implantation.

Robot-Guided Stereotactic Puncture and Drainage in the Treatment of Thalamic Abscess.

Brain abscess is rare in clinic, the reported incidence is only 0.4 to 0.90 per 100,000 population, and most of them have a history of prodromal infection. Headache and fever are the most common clinical symptoms, and only a few are accompanied by neurological disorders. For the treatment of brain abscess, the most commonly used treatment is stereotactic puncture drainage and antibacterial therapy. A patient with a left thalamic abscess with no history of prodromal infection was reported. Stereotactic puncture and drainage were performed under the guidance of the Ruimi robot. The bacterial culture of the abscess was Streptococcus constellation ( Streptococcus constellatus ). The patient was discharged after 4 weeks of antibacterial treatment with vancomycin. The patients were followed up half a year after the operation, the prognosis was good and there was no recurrence.
