Objective To evaluate the efficacy and clinical significance of medical chemical glue as an external stent in improving the fluency rate of venous bypass graft after coronary artery bypass grafting .Methods Randomly selected 200 pa-tients from April 2010 to December 2016 included who were underwent coronary artery bypass grafting in Beijing Anzhen Hospi-tal.All patients had different degrees of angina , and coronary angiography showed multi-branches artery lesion.They were ran-domly divided into two groups, 100 in each group.Spray gel group: coronary artery bypass grafting simultaneously spraying medical chemical glue on the surface of the bridge vessel.Unsprayed gel group:simple coronary artery bypass grafting.All 200 patients were followed up in June 2018.The follow-up content mainly included: recent recurrence of angina pectoris, recent echocardiography and electrocardiogram report, coronary CTA or coronary angiography results, and current living conditions. The data obtained were collectively summarized and compared .Results The follow-up rate was 96% in the sprayed group, and 92% in the unsprayed group.Compared with the unsprayed group , the incidence of chest pain and angina pectoris was significantly lower in the sprayed group(23.96% vs.40.22%, P<0.05), the venous occlusion rate of the vein bypass graft in the sprayed group was significantly lower(29.17% vs.55.43%, P<0.01), the probability of death due to cardiac causes in the sprayed group was significant decrease(1.04% vs.6.52%, P<0.05), the number of patients with the main adverse cardiac and cerebral events(MACCE) in the sprayed group was significantly lower(9.38% vs.21.74%, P<0.01), all with statistically significant differences .The number of patients with heart failure and recurrent myocardial infarction was lower in the sprayed group, but there were no statistically significant differences .Conclusion Medical chemical glue as an external stent does play a role in improving the venous patency rate after coronary artery bypass grafting , and it is reliable for the preven-tion and treatment of vein bypass vascular stenosis after coronary artery bypass grafting .

The authors reports a case of giant carotid artery aneurysm at the cavernous portion which was treated by trapping of internal carotid artery(ICA) after external carotid artery(ECA) to middle cerebral artery(MCA) bypass by long saphenous vein graft. It was impossible to clip the aneurysm because of its position and size. The patient suffered from progressive extraocular movement disturbance and decreased visual acuity. She was intolerant to ballon occlusion test. The size of the aneurysm was 3.5x2.5x2 cm. ECA to MCA bypass was done with saphenous vein graft successfully. However, computerized tomography shows hemorrhagic infraction at left temporal lobe postoperatively. Two days later, left temporal lobectomy was done because of uncontrollable increased intracranial pressure. Internal carotid artery was trapped with proximal ligation and distal clipping at the supraclinoid segment.
