Atherosclerosis mainly occurs in the large and medium arteries in the body, especially the cerebral arteries and coronary arteries. The two often occur at the same time, and have the common characteristics of thickening, hardening, loss of elasticity and contraction of the arterial wall. Clinically, when coronary artery stenosis and carotid artery stenosis coexist, the current treatment options mainly include: simultaneous treatment and staged treatment. When cerebral arteries are also severely stenotic, whichever procedure is performed first carries high perioperative risks. Therefore, in this case, both lesions should be treated simultaneously. Since the treatment regimens and medication strategies of the two diseases are similar, it is relatively easy to achieve combined treatment. From our research results, no matter whether the patients are treated via radial artery or femoral artery, the LVEF of the two groups can be effectively improved, and there is no difference between the two methods, which shows that the radial artery and femoral artery intervention Both can guarantee the therapeutic effect of patients and improve vascular function. But we found that TRA had a shorter operation time, and patients' bed rest and hospital stay were shorter.
TRA diagnosis and treatment of coronary artery is very mature, but the time of neurointerventional diagnosis and treatment is still short. Cerebral angiography by TRA began to be reported around 2000 [9–10]. Cerebral angiography via the femoral artery is a traditional clinical approach with long application experience, because the internal diameter of the femoral artery is large, it has a high success rate in puncture, and the difficulty of clinical operation is low, so it has been widely used clinically. With the development of clinical application, the problems of this approach are constantly exposed. For example, postoperative immobilization time of patients should be more than 24 hours, and postoperative patients are prone to pseudoaneurysm and large hematoma at the puncture site[11]. Obese patients will increase the difficulty of puncture and hemostasis, and patients are more prone to pseudoaneurysm. Furthermore, the transfemoral approach is not indicated for patients with spinal deformities [12]. In recent years, with the continuous improvement of interventional diagnosis and treatment technology, more and more medical centers have begun to use TRA as an optional path for nerve interventional diagnosis and treatment, and even use TRA as the preferred puncture method [13–14]. Common complications of TRA puncture include radial artery bleeding, hematoma, compartment syndrome, radial artery spasm, and radial artery occlusion. Compared with the complications of TFA, it is lighter and easier to handle.
We believe that the therapeutic effect is related to the proficiency of the operation and the severity of the disease. It has been suggested that the risk of complications is higher when treating both cerebral and coronary artery disease than when treating a single lesion. However, the results of this study showed that postoperative complications did not increase, indicating that combined heart-brain angiography has good safety. The RIVAL study is a multicenter randomized double-blind controlled study that compared the complication rates of TRA and TFA in patients undergoing coronary artery diagnosis and treatment. The study showed that TRA-related complications were lower than those of TFA [15]. In our study, the overall complication rate of TFA was 18.3%, with hematoma and pseudoaneurysm as the main causes. The patient with hematoma at the puncture point improved after hemostasis by recompression, bandaging and bed rest, without special treatment. The complication rate of TRA group was 8.3%, which was significantly better than that of TFA. In 2021, the results of a Chinese study were consistent with ours, showing that the total complications of vascular puncture in SCCAG patients in the TRA group were less than those in the TFA group [2].
The length of stay is an important indicator for evaluating the utilization efficiency of medical centers, and many studies have focused on the influencing factors of LOS [16–17]. Previous studies have shown that TFA patients need to stay in bed after surgery, while TRA patients have good hemostatic effect and do not need to stay in bed, which will inevitably lead to a significant reduction in LOS, and even meet the requirement of being discharged on the same day [18]. This study also suggested that, in terms of SCCAG patients, LOS was less in the TRA group. This not only helps to increase the comfort of patients, but also can effectively save medical resources under the premise of the current shortage of medical resources, and create a more convenient medical environment for more patients with urgent needs at the same time.
There are some limitations in this study. First, this study is a single-center study, which only reflects the initial experience of using TRA to perform SCCAG in this center. Second, the amount of data included is small. In the next step, we will continue to include data on the basis of this study for further discussion. In conclusion, according to the data of this study, TRA puncture for SCCAG is clinically feasible, relatively safe, and can reduce the hospitalization time of patients.
