RESUMO
AIM: To report surgical treatment of a ruptured abdominal aortic aneurysm (AAA) associated with spondylodiscitis due to Salmonella in emergency setting. CASE REPORT: A 69-year-old male with an history of hypertension, presented with a ruptured AAA infected by nontyphoidal Salmonella (type H), associated with spondylodiscitis. Patient underwent an emergency operation consisting in surgical debridment of infected tissue and aortic replacement with a prosthetic Dacron graft impregnated with Gentamycine. The postoperative course was uneventful and the patient was discharged at day 20 after the index procedure in good clinical condition. antimicrobial therapy was continued for 8 weeks. A CT scan and nuclear medicine studies performed two months later demonstrated minimal sign of residual aortitis. A CT scan 21 months after the procedure showed complete anatomic resolution of the disease. CONCLUSIONS: A rare but increasing number of aneurysms as a consequence of Salmonellosis can be observed with a high rate of morbidity and mortality, mainly in patients with a concurrent infection of the spine and paravertebral tissue. Combined antimicrobial therapy and one-stage surgical treatment can be associated with good outcome. KEYWORDS: Abdominal aorta aneurysm, Mycotic aortic aneurysms, Salmonellosis, Spondylodiscitis.

AIM: The purpose of this study was to examine the influence of aneurysm size on early outcome in women undergoing abdominal aortic aneurysm (AAA) repair, with suggestion of lowered threshold for intervention. PATIENTS AND METHODS: Retrospective cohort study on the early outcome of 25 females undergoing elective endovascular (EVAR) and open AAA repair, compared to 340 males from 2005 to 2017. The study was focused on 30-days mortality (primary endpoint) and incidence of non fatal major adverse events - MAE (secondary endpoint) of two subgroups of women: AAA diameter <50 mm (n.14, group F1), AAA diameter ≥ 50mm (n.11, group F2). RESULTS: The incidence of the primary endpoint at 30 days was 4% in females, and 1.1% in males, respectively (p=ns). Similarly, females showed a higher rate of MAE compared to males (16% vs 9.4%, p=ns). Women who underwent surgery with small aneurysms (F1 group) had an early outcome similar to men (30-day death 0% vs 1.1%, p=ns; MAE 7.1% vs 9.4%, p=ns) and significantly better than women with larger aneurysms (30-day death 0% vs 9%, p=ns; MAE 7.1% vs 27.2, p=ns). CONCLUSIONS: Although poorly significant from a statistical point of view, the present report seems to confirm that the AAA diameter is a relevant marker of disease severity in women, assuming that repair at smaller size may be associated with less comorbidity and better outcome.

BACKGROUND: The fate of aortic ectasia associated with aortic valve disease is usually derived from the natural history of primitive aortic aneurysm. We evaluated the evolution of untreated aortic dilation following aortic valve replacement and analyzed risk factors for expansion. METHODS: Thirty-eight patients undergoing aortic valve replacement, with an aortic diameter 40 to 55 mm, were followed up for a mean of 42 +/- 28 months (median 36 months). Freedom from adverse events, velocity of aortic expansion and correlation between velocity and several potential risk factors were evaluated. RESULTS: The mean aortic diameter did not change over time (43 +/- 4 vs 44 +/- 12, p = NS). Velocity of aortic expansion correlated significantly with the diameter of the ascending aorta at the time of operation, with faster growth in patients with ascending aorta diameter > 50 mm (p = 0.0004). Patients with aortic regurgitation had a tendency to a faster aortic dilation compared to those with aortic stenosis (p = 0.10). CONCLUSIONS. In patients without other risk factors, prophylactic surgical treatment of the ectasic aorta seems advisable for diameters > 48 mm. For diameters < 43 mm no treatment is probably needed. Other aspects must be considered for appropriate surgical strategy in the interval between 43 and 48 mm. Patients with aortic regurgitation should be closely monitored.

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.

BACKGROUND: The presence of significant carotid artery disease in patients undergoing coronary artery bypass grafting has been reported to be as high as 17%. The optimal management of patients with significant coronary and carotid artery disease remains controversial. In this study, we analyze our recent experience with patients who underwent synchronous carotid endarterectomy (CEA) and coronary artery bypass grafting. METHODS: We reviewed the early outcome of 68 patients (56 males, 12 females, mean age 71.1 years, range 53-88 years) who underwent simultaneous CEA and coronary artery revascularization between January 2005 and June 2007. The frequency of unstable or ulcerated plaques was determined in symptomatic and asymptomatic patients. RESULTS: Death for myocardial infarction occurred in 3 patients (4.4%). Stroke was found in 1 patient (1.4%). Combined 30-day stroke/mortality rate was 5.8%. The frequency of unstable or ulcerated plaques was 60.3% (41/68). An unstable stenosis was present in 23 out of 42 asymptomatic patients (54.7%). CONCLUSIONS: Patients suffering from a concomitant coronary and carotid artery occlusive disease represent a high-risk population whose management is still controversial. A modern approach to combined CEA and coronary artery bypass grafting may be safe. The high frequency of unstable carotid lesions in asymptomatic patients suggests to treat every stenosis > 75% in candidates to coronary artery bypass grafting. Carotid artery stenting should be avoided in the majority of cases, considering the possibility of unstable carotid stenosis and the atherosclerotic involvement of aortic arch.
