Analysis of The Preventive Effect of Nursing Intervention on Complications After Whole Cerebral Angiography

Objective: To analyze the effect of nursing intervention in preventing complications after whole-brain angiography and reducing the risk of neurological dysfunction, infection, and vascular complications. Methods: One hundred patients who underwent whole-brain angiography in our hospital from December 2022 to December 2023 were selected and randomly divided into control and observation groups of 50 cases each. The control group received routine care, and the observation group received systematic care. The psychological status, complication rate, nursing quality, blood pressure, and nursing satisfaction of the two groups of patients were compared. Results: Before the intervention, there was no significant difference in psychological state between the two groups (P > 0.05). After the intervention, the positive effect (PA) and negative effect (NA) exhibited a significant correlation between the two groups (P < 0.05). The observation group had a lower incidence of postoperative complications as compared to the control group (P < 0.05). The nursing quality and satisfaction of the observation group were significantly higher than those of the control group (P < 0.05). There was no significant difference in blood pressure levels between the two groups before surgery (P > 0.05), while during and after surgery, the blood pressure levels of the two groups of patients showed a highly significant correlation (P < 0.05). Conclusion: Nursing intervention exhibited a significant preventive effect after whole-brain angiography. Scientific and reasonable nursing measures can effectively reduce the incidence of complications and improve the surgical safety and recovery of patients.

Role of cerebral digital subtraction angiography in the evaluation of pulse synchronous tinnitus

Objectives: The aim of this study was to evaluate the value of digital subtraction angiography (DSA) in thediagnostic evaluation of a highly selected patient population presenting with pulse-synchronous tinnitus(PST).Methods: We retrospectively reviewed the charts of all patients referred for evaluation of possiblevascular etiology of pulsatile tinnitus. Patients were evaluated with regards to presenting signs,comorbidities, non-invasive imaging results, angiographic findings and outcomes.Results: Fifteen patients underwent cerebral DSA. Dural arteriovenous fistula (dAVF) was identified in sixpatients, and five patients had other significant vascular pathology identified on DSA. Seven patientswith ‘negative’ non-invasive imaging were found to have significant pathology on DSA.Conclusions: Catheter angiography may have a significant yield in appropriately selected patients presenting with pulse synchronous tinnitus.

Head dual energy-computed tomography angiography versus neuro-digital subtraction angiography

Dual-energy X-ray absorptiometry provides two modes of head computed tomography （CT） angiography scanning： neuro-digital subtraction angiography and dual-energy CT angiography （DE-CTA）. Previous studies have compared image quality, radiation exposure, and bone removal between neuro-digital subtraction angiography and DE-CTA. However, the number of cases was relatively small. The present study examined 300 suspected cases of cerebrovascular disease and observed the methods and duration of post-processing, examination time, and data volume. Results demonstrated similar image quality between the two methods, but lower radiation doses and shorter examination time in DE-CTA. DE-CTA allowed for faster and more stable scanning performance and post-processing methods, facilitating accurate and direct diagnosis of cerebrovascular disease.

Combined application of virtual imaging techniques and three-dimensional computed tomographic angiography in diagnosing intracranial aneurysms

Background The diagnostic value of virtual imaging combined with three-dimensional computed tomographic angiography （3D-CTA） for intracranial aneurysms has not been fully elucidated yet. This study aimed to evaluate the value of combined application of virtual imaging techniques and 3D-CTA in diagnosing patients with aneurismal subarachnoid hemorrhage （SAH） at the acute stage. Methods Eighty patients with non-traumatic SAH received 3D-CTA examinations. The raw CT data of these patients were reconstructed and transferred into the 3D mode through the surgical plan system based on virtual reality （VR） image, and the 3D virtual images of skulls and brain blood vessels were acquired. The location, size and shape of aneurysms and their anatomic relationship with adjacent tissues were measured from many points of view. Results Seventy-three aneurysms were detected in 68 of the 80 patients, but 2 aneurysms were detected in 2 of the 5 patients who had been found free of aneurysms previously and had received 3D-CTA examinations for a second time one month later. The 3D virtual images produced by the virtual imaging system were clear and vivid, and they could reveal the location and size of the aneurysm and its relations to the parent artery and skull directly. Conclusions The imaging of 3D-CTA is convenient, reliable and fast in diagnosing intracranial aneurysms and can be regarded as the first choice for the diagnosis and treatment of ruptured intracranial aneurysms. Combined with the surgical plan system based on the VR image, 3D-CTA may obtain more imaging information about aneurysms.

Postoperative recovery from posterior communicating aneurysm complicated by oculomotor palsy

Background Oculomotor palsy is a common complication in patients with posterior communicating aneurysm. This study was conducted to investigate the postoperative recovery of patients with posterior communicating aneurysm complicated with oculomotor palsy and to analyze the factors influencing length of recovery.Methods From 2000 to 2006, 148 patients with posterior communicating aneurysm were treated at our hospital, with 74 of them having concurrent unilateral oculomotor palsy. All of the patients underwent craniotomy after the diagnosis by means of whole-brain digital subtraction angiography （DSA）. The patients were divided into two groups for observation of postoperative recovery during the follow-up period. Patients in group A were treated with simple pedicle clipping of the aneurysm while patients in group B were treated with pedicle clipping of the aneurysm and decompression of the oculomotor nerve.Results Of the 40 patients in group A, 20 underwent surgery within 14 days and completely recovered from oculomotor palsy in 10-40 days. Fourteen patients underwent surgery within 14-30 days, of whom 12 completely recovered within 30-90 days and 2 cases recovered incompletely. The remaining six patients underwent surgery after more than 30 days; of these, four patients recovered completely and two recovered incompletely. Of the 34 cases in group B, 15 underwent surgery within 14 days and completely recovered from oculomotor palsy in 10-40 days. Sixteen patients underwent surgery in 14-30 days, of whom 14 completely recovered in 30-90 days and 2 recovered incompletely. The remaining three patients underwent surgery after more than 30 days, of whom two patients recovered completely and one recovered incompletely.Conclusions Early diagnosis and surgical treatment of patients with unilateral oculomotor palsy induced by posterior communicating aneurysm are important to full postoperative recovery of the oculomotor nerve. No correlation was found, however, between decompression of the oculomotor nerve, such as excision or puncture of the aneurysm, and postoperative recovery time.
