ANASTOMOTIC FALSE ANEURYSM FOLLOWING ABDOMINAL AORTIC ANEURYSMECTOMY AND PROSTHETIC GRAFTING

Anastomotic false aneurysm (AFA) of the aorta is a potentially lethal complication after prosthetic grafting. Nineteen aneurysms were encountered in 18 patients within a 30-year period (1960-1991). There were 10 men and 8 women, aged 27?0 years (mean 58 years). In 14 patients, the prostheses were made of silk, in 2 were PTFE, and in 1 each Dacron or silk-Dacron cross-weaved. Patients with an intact AFA had a pulsatile abdominal mass, abdominal pain, an oc culuded graft and peripheral emboli. Five patients were asymptomatic. Clinical onset of AFA varied from 2 weeks to 12 years (mean 5 years). The accurate rate of diagnosis of single plane angiography was 75% (3 of 4), and computed tomography 100% (ten of ten). Ultrasound was used only once and suggested an AFA. Four AFAs were less than 5cm in diameter. Five patients refused operation and died in 2 years from rupture. Operative mortality was 11% (1 of 9). Treatment was resection of AFA and replacement with a new graft. Life-ong follow-p is required for patients with an aortic aneurysm. All ratroperitoneal AFAs should be resected, since the outcome of rupture is poor.

Anesthesia with ciprofol in cardiac surgery with cardiopulmonary bypass:A case report

BACKGROUND Ciprofol is a novel agent for intravenous general anesthesia.In February 2022,it was approved by the National Medical Products Administration for general anesthesia induction and maintenance.It has the advantages of fast onset,fast elimination,stable circulation,and few adverse reactions.However,the efficacy and safety of ciprofol in cardiac surgery with cardiopulmonary bypass have not been reported.Here we describe a case where ciprofol was successfully used for anesthesia in cardiac surgery with cardiopulmonary bypass.CASE SUMMARY A 72-year-old man(height 176 cm;weight 70 kg)was diagnosed with coronary atherosclerotic cardiomyopathy requiring coronary artery bypass grafting and left ventricular aneurysmectomy.Ciprofol was administered for induction(0.4 mg/kg)and maintenance(0.6-1.0 mg/kg/h)of general anesthesia.During the entire operation,the bispectral index,hemodynamics,and blood oxygen saturation were maintained at normal levels.The patient recovered well after surgery,with no serious adverse events related to ciprofol.CONCLUSION Ciprofol is safe and effective for anesthesia in cardiac surgery with cardiopulmonary bypass.

Coronary artery bypass grafting for Kawasaki disease

Background Kawasaki disease （KD） is the leading cause of pediatric ischemic heart disease. The incidence of serious coronary sequelae is low and about 2%-3% of patients with KD, but once myocardial infarction occurs in children, the mortality is quite high and 22% at the first infarction.This study aimed to evaluate the efficacy of coronary artery bypass grafting （CABG） in patients with KD. Methods Eight patients with a history of KD underwent CABG between October 1997 and July 2005. The number of bypass grafts placed was 2 to 4 per patient （mean 2.5±0.8）. Various bypass grafts were used in patients, i.e. the left internal mammary artery （LIMA） in 3 patients, bilateral internal mammary artery （IMA） in 2 patients, LIMA plus gastroepiploic artery （GEA） in 1 patient and total saphenous vein grafts （SVGs） in 2 patients. The combined procedures included ventricular aneurysmectomy in 1 patient, mitral valve plasty in 1 and right coronary aneurysmectomy in 1. One patient was not able to wean from cardiopulmonary bypass （CPB）, after being supported with intra-aortic balloon pump （IABP）, the patient was weaned from CPB successfully. Results One patient died of low cardiac output syndrome and acute renal failure 19 days after operation. Other patients recovered and were discharged uneventfully. During the follow-up that ranged from 3 to 57 months （mean 27 months）, clincal angina disappeared or improved. Cardiac function was in Class I-II （NYHA）.Conclusion CABG is a safe and effective procedure for Kawasaki coronary artery disease. However long-term results need to be followed up.
