We used the same catheter to perform selective coronary angiography + peripheral arteriography + PTCA (percutaneous transluminal coronary angioplasty). After diagnosing the stenosis of the left anterior descending coronary branch and the stenosis of the left internal carotid artery, we inserted stents into the stenoses respectively. Mr. Yang walked back to the ward after the operation and was discharged from the hospital after 7 days of recovery. In the past, patients like Mr. Yang had to go through two procedures of coronary angiography + PTCA in cardiovascular medicine and peripheral arteriography + PTCA in neurology. In August 2006, our department performed the first case of using 5F multifunctional contrast tube via radial artery, which pioneered the use of the same catheter for coronary angiography and peripheral angiography of cerebral vessels and renal arteries in the field of cardiovascular intervention. A research paper was published in the International Journal of Cardiology. Radial Artery Pathway What are the advantages? With the development of interventional radiology, vascular intervention has become an important treatment method, playing an important role in the diagnosis and treatment of cardiac macrovascular diseases, head, neck and central nervous system diseases, tumors and peripheral vascular diseases. Interventional vascular pathways range from the earliest femoral and brachial arteries to the radial artery pathway. Since the beginning of radial artery pathway coronary angiography in 1989, the indications for coronary intervention have been extended to the treatment of unprotected left main lesions, bifurcation lesions, chronic occlusive lesions, acute myocardial infarction and other conditions. Clinical studies and practice have shown no difference in the efficacy of radial and femoral artery pathway interventions. Among the femoral artery, brachial artery and radial artery, although the femoral artery is thick and straight, it requires patients to stay in bed for a long time and is prone to serious complications such as pulmonary embolism, pseudoaneurysm and arteriovenous fistula; the brachial artery is prone to bleeding and osteofascial syndrome; the radial artery not only has fewer complications, but also is easy to stop bleeding and does not require bed rest after treatment. Therefore, radial artery pathway vascular intervention is becoming the first choice. However, it is difficult to perform whole brain angiography via radial artery with a shared contrast tube, and the operator needs to operate and explore more skills. What is the value of multi-site operation? In our clinic, we found that about 30% of patients with coronary artery stenosis have combined stenosis of renal artery and carotid artery and vertebral artery. In clinical subspecialties, these stenoses belong to cardiovascular medicine, hypertension endocrinology or nephrology, neurology, etc. Traditionally, interventional treatment is carried out by each department according to the location of stenosis. As a result, it increases the time, pain and economic burden of patients. When a patient’s condition requires intervention at two or more sites, the value of multi-site intervention with the same catheter comes to the fore. In the case of 3 sites, for example, if the imaging is done in sections, the cost of treatment is more than 20,000 yuan, and the patient has to experience the pain and prolonged treatment time of 3 imaging sessions, while with multi-site interventional treatment with the same catheter, the imaging and stent implantation can be completed in one session, and for each additional site, only the cost of the contrast agent is increased, and the imaging of 3 sites is less than 10,000 yuan. Multi-site operation Is it safe? Currently, coronary and peripheral artery angiography and vascular intervention using different catheters via radial artery have been widely reported internationally, but there are not many bulk reports using the same catheter. We performed selective coronary, cerebrovascular, and renal artery angiography in 1092 patients (607 men and 485 women) using a 5F multifunctional contrast tube via the radial artery pathway and counted the incidence of complications. The results showed that 1081 of 1092 patients (99%) underwent successful puncture, and 11 failed puncture mainly due to radial artery spasm or radial artery developmental malformation. Seven did not complete the angiogram due to brachial artery spasm. The mean completion time for the entire angiogram was 26.9 clay 9.3 minutes, and the overall complication rate was 4.35%, including swelling of the right hand, arterial spasm, diminished radial artery pulses, and radial artery pseudoaneurysm. There was no case of transient hand ischemia, embolism or puncture site hematoma. Transradial angiography has proven to be feasible and safe, with low cost and short hospital stay for the entire procedure. The same catheter radial artery pathway multi-site angiography technique has obvious advantages in clinical application and is now accepted by patients and has been performed in more than 10 hospitals in China, which has caused great social repercussions.
