An analysis of the causes of death for patients of peripheral arterial disease during the perioperative period / 中华普通外科杂志

ABSTRACT

Objective To investigate the causes of death and the influencing factors in patients with peripheral arterial disease(PAD) during the perioperative period and reduce the perioperative mortality.Methods A retrospective analysis of the causes of death was performed for PAD during the perioperative period in our hospital from July 2005 to July 2010. Results Nine patients died preoperatively.The causes of death were multible organ failure in 5,heart failure in 2,sudden cardiac death in 1,and respiratory failure in 1.Six patients died postoperatively.The causes of death were acute renal failure in 2,heart failure in 2,cerebral infarction in 1,and hemorrhagic shock in 1.The causes of death which were related to heart,kidney and lung were in 10,6 and 2,respectively.The causes of death which were directly due to heart failure,sudden cardiac death,renal failure,respiratory failure,cerebral infarction and hemorrhagic shock were in 4,1,2,1,1 and 1,respectively.The main causes of death were multible organ failure,heart failure and acute renal failure,which accounted for 73.33％ of all deaths.In this series the overall perioperative mortality was 3.11％ (15/483),Operative mortality was 1.47％ (6/407).Conclusions The influencing factors and the function of organs were closely correlated with the causes of death. To reduce the perioperative mortality of PAD,it is necessary both to intervene in the influencing factors and to monitor and treat the dysfunction of vital organs.
