RESUMEN
BACKGROUND: The management of abdominal compartment syndrome (ACS) has been included as a standard of care in our therapeutic algorithm after diagnosis of acute mesentheric ischemia (AMI), following cardiac surgery. This report is an updated review of our results compared to previous experience. MATERIALS AND METHODS: A retrospective, observational, cohort study on a series of 26 patients (20 males, 6 females, mean age 75.2 years, min 64, max 83) who developed AMI, out of 7.719 patients undergoing cardiac operations (january 2005 - December 2014). The initial treatment consisted of laparotomy with abdominal decompression and temporary abdominal closure, performing visceral resections just in case of gangrenous tracts and providing for a "secondlook" during the variable period of resuscitation and vacuum assisted dressing. RESULTS: A non-occlusive mesentheric ischemia with diffuse visceral underperfusion was confirmed in every case. Temporary abdominal closure was applied to treat ACS in every case, 13 patients required associated resection of gangrenous tracts (50%). Seventeen patients died following first operation as a consequence of multiple organ failure (65.4%). Nine patients survived (34.6%) and underwent re-establishment of intestinal continuity and definitive closure of abdominal wall within 30 DAYS. DISCUSSION AND CONCLUSIONS: AMI occuring after cardiac surgery is associated with an increase of intra-abdominal pressure and subsequent ACS. Basing on this case series, an early ACS treatment using open abdomen techniques may be results in a better outcome of critically injured cardiac patients. These results compared favourably with literature experiences (mortality rate > 85%). KEY WORDS: Abdominal compartment syndrome, Acute mesentheric ischemia, Cardiac surgery.

BACKGROUND: Current guidelines do not recommend routine coronary evaluation preceding abdominal aortic aneurysms (AAA) repair in low-risk patients. The purpose of the present study is to report the incidence of coronary lesions in candidates for AAA repair with a Revised Cardiac Risk (Lee) Index (RCRI)â<â2, which are usually excluded from preoperative cardiological work-up. Early-term and long-term results of prophylactic myocardial revascularization are also reported. METHODS: A retrospective, observational, cohort study collecting clinical data on a series of 149 consecutive patients undergoing preoperative coronary angiography and myocardial revascularization (percutaneous coronary intervention, PCI; coronary artery bypass grafting, CABG) before elective open or endovascular AAA repair (January 2005-December 2012). RESULTS: Severe coronary artery disease (CAD) was revealed in 43 patients (28.9%), who underwent successful myocardial revascularization by means of PCI (n.35) or off-pump CABG (n.8). The incidence of severe CAD in patients resulted at low risk on the basis of risk models was approximately 25%. The incidence of severe CAD in asymptomatic patients was 29.8%. Endovascular (n.52, 35.1%) and open (n.96, 64.9%) AAA repair was performed with low morbidity (0.6%) and mortality (0.6%) in 148 patients. The long-term estimated survival (freedom from fatal cardiovascular events) was 97% at 60 months and 82% at 90 months. CONCLUSIONS: The incidence of severe correctable CAD is not negligible in low-risk patients scheduled for AAA repair. Waiting for further recommendations based on large population studies of vascular patients, a more extensive indication to coronary angiography and revascularization should be considered in many candidates for AAA repair.
