Clinical Effect of Digital Subtraction Angiography Combined with Neurointerventional Thrombolysis for Acute Ischemic Cerebrovascular Disease and Its Influence on Vascular Endothelial Function and Oxidative Stress

Abstract

Objective. Ischemic cerebrovascular disease is a commonly seen vascular disorder in clinical practice. Given the difficulty of drug therapy to achieve ideal curative effects, interventional therapy has gradually become the preferred treatment for the disease. This research primarily discusses the short-term efficacy of digital subtraction angiography- (DSA-) guided neurointerventional thrombolysis for acute ischemic cerebrovascular disease (AICVD) and its influence on vascular endothelial function (VEF) and oxidative stress (OS). Methods. All the clinical data of 162 patients diagnosed with AICVD and treated between June 2019 and December 2021 were collected and analyzed retrospectively. They were assigned to two cohorts according to the difference in interventional methods: a conventional group (CG) given recombinant tissue plasminogen activator (rt-PA) therapy and an observation group (OG) intervened by DSA-guided neurointerventional thrombolysis. The two groups were compared with respect to short-term treatment efficacy, the National Institutes of Health Stroke Scale (NIHSS) score, cerebral hemodynamics, and VEF and OS indexes. Results. The short-term efficacy was better in OG (93.98%) than in CG (82.28%). After treatment, the NIHSS score decreased in both cohorts with obvious differences within the group at different time points, and the posttreatment NIHSS score was lower in OG as compared to CG. OG had higher Q m and V m while lower W v , Z cv , and R v than CG. Higher endothelial-dependent flow-mediated dilatation (FMD) was observed in OG, as well as lower ankle-brachial index (ABI) and pulse wave velocity (PWV). And the posttreatment MDA was lower while SOD, GSH-Px, and TAC were higher in OG compared with those on CG. All the above differences were of statistical significance ( P < 0.05 ). Conclusions. DSA-guided neurointerventional thrombolysis is highly effective in the treatment of AICVD, which can not only effectively improve patients’ neurological function and cerebral hemodynamics but also mitigate VEF injury and help to alleviate patients’ OS.

Effects of glycemic indicators on early neurological outcomes in patients with acute ischemic stroke treated with intravenous thrombolysis

“…In addition, hyperglycemia can also impair cerebral autoregulation, which lead to reperfusion injury and lower rate of recanalization in AIS patients with rt-PA intravenous thrombolysis [41]. Moreover, stress hyperglycemia is reported to be associated with greater in ammatory and neurohormonal responses, increased induction of endothelial apoptosis, and increased oxidative stress and increases the risk of brain edema, and hemorrhage after IVT [42,43]. Studies also reported that both acute and chronic hyperglycemia play an important role in prothrombotic shift and may facilitate thrombus extension, which has a strong association with END [44,45].…”

“…Diseases of the central nervous system often manifest as neuronal death. ere is increasing evidence that oxidative stress is important pathogenesis of many central nervous system diseases [16][17][18]. erefore, inhibiting oxidative stress can reduce neuronal damage, which is of positive significance for the prevention and treatment of neurological diseases.…”
