Simultaneous coronary artery bypass grafting and ascending aorta to bifemoral bypass for ischemic heart disease combined with critical leg ischemia: case reports.

Coronary artery disease may coexist with aortoiliac occlusive disease, and concomitant revascularization procedures may be required. The ascending aorta may be used as the source of inflow to both the femoral and coronary arteries in patients who present with coronary artery disease and critical leg ischemia. We present here 2 patients in whom coronary artery bypass grafting and ascending aorta-to-bifemoral bypass operations were performed simultaneously.

Simultaneous carotid endarterectomy and myocardial revascularization by using cardiopulmonary bypass for both procedures.

OBJECTIVE: The optimal treatment of patients with co-existing occlusive coronary and carotid arterial disease is controversial. This study reports our experience with simultaneous carotid endarterectomy and coronary bypass in conjunction with cardiopulmonary bypass with mild hypothermia. METHODS AND RESULTS: From March 2001 to June 2004, 72 patients underwent simultaneous coronary bypass and carotid endarterectomy. Their mean age was 68.9 years and there were 56 men and 16 women. The indication for carotid endarterectomy was a lumen diameter reduction of more than 75% and/or the presence of ulcerated/unstable plaque. Carotid endarterectomy was done during cardiopulmonary bypass under mild hypothermia, haemodilution, systemic heparinization and controlled haemodynamics under pulsatile perfusion for additional cerebral protection. The mean cardiopulmonary bypass time was 64.7 minutes and aortic cross-clamp time 32.4 minutes, and the mean number of grafts per patient was 2.7. Four patients had perioperative neurological complications (5.5%) and two had permanent deficits (2.7%). The procedure-related mortality was 3 (4.1%). CONCLUSIONS: We suggest that combining coronary revascularization and carotid endarterectomy and performing both under cardiopulmonary bypass is safe, offering acceptable morbidity and mortality rates.

Isolation ratio and T- serotyping of group A streptococci from pediatric upper respiratory tract infections in Turkey.

OBJECTIVE: Acute rheumatic fever can follow throat infections with group A streptococci. Certain serotypes of group A streptococci such as M1, M3, M5, M6, M14, M18, M19, M24 are associated with this disorder. Immunity to streptococci and to rheumatic fever depends on antibodies to the M proteins. Due to current scarcity of M-typing sera, many laboratories use T typing and opacity factor production for serotype identification of group A streptococci. In order to, investigate the most common serotypes of group A streptococci in our country in recent years we studied T-agglutination typing and opacity factor of 120 group A streptococci strains isolated from throat cultures of 930 children. METHODS: Diffuse, stable suspensions of group A streptococci were tested with polyvalent antisera (T,U,W,X,Y) by slide agglutination. Microplate method was used for opacity factor detection. RESULTS: T-protein -agglutination patterns U (2,4,6,28) were the most common among typeable strains. The rate of T-protein -agglutination patterns T (1,3,13, B3264) and X (8,14,25,Imp.19) were 20 % and 18 % respectively. Opacity factor production rate of isolated group A streptococci strains was 65%. CONCLUSION: To profit global assessment of rheumatic fever and rheumatic heart disease, more epidemiological and serotyping research is required in our country.

A Mediastinal False Aneurysm with Aortocutaneous Fistula.

Abstract In this report, we present a case of the development of a false aneurysm of the ascending aorta with an aortocutaneous fistula in a 57-year-old patient 10 months following aortic valve replacement and concomitant coronary bypass surgery.

Reduction aortoplasty and external wrapping for moderately sized tubular ascending aortic aneurysm with concomitant operations.

BACKGROUND: Replacement of the ascending aorta with a prosthetic graft is the preferred surgical procedure for an ascending aortic aneurysm. The choice of external wrapping of the aorta is a simple, fast, and effective method for moderately sized ascending aortic aneurysms with concomitant operations. In this study, we present the midterm results of 62 patients undergoing reduction aortoplasty with external wrapping and different cardiac procedures. METHODS: The study group consisted of 48 male and 14 female patients with a mean age of 59.3 +/- 6.0 years. Measurement of the ascending aorta diameters was obtained at three points: before surgery, during the early postoperative period, and during the follow-up. The mean preoperative aortic diameter was 52.7 +/- 0.5 mm. In all patients, the ascending aortic aneurysm was repaired by reduction aortoplasty with external wrapping. RESULTS: Mean follow-up time was 39.6 +/- 18.0 months. There was only one mortality (1.6%) as a result of septic multiple-organ failure and no major surgical complications in the 30-day postoperative period. Reduction aortoplasty of the ascending aorta with external wrapping resulted in a significant reduction of the ascending aorta in all patients (p = 0.000). There was an increase in the mean aortic diameter during the follow-up period (p = 0.000). Although this increase was statistically significant, all measurements of the follow-up period were still within normal range. CONCLUSIONS: External wrapping of the aorta offers excellent results with very low mortality and morbidity, and it can be regarded as a safe and effective method for the treatment of ascending aortic aneurysm in selected patients. However, the patients should be carefully monitored for redilatation after the procedure.

Delayed rupture of a postinfarction left ventricular true aneurysm.

Delayed rupture of a true left ventricular aneurysm is a rare clinical condition. We report a case of a 60-year-old woman who underwent emergency surgical repair of a ruptured true aneurysm of the left ventricular inferior wall 3 months after the myocardial infarction. The repair consisted of endoaneurysmorraphy patch technique. The patient made a satisfactory recovery.

Coronary artery bypass surgery in patients with severe left ventricular dysfunction.

OBJECTIVE: The role of coronary artery bypass grafting (CABG) in patients with severe left ventricular dysfunction was evaluated. METHODS: Two hundred and twelve patients (152 men, 60 women; age 35 to 82, mean 55) with ejection fraction (EF) of less than 30% underwent CABG between January 1996 and February 2001 by a single surgeon (SA). They compromised of 12% of 1759 patients operated on in this period. EF ranged from 17% to 30% (mean 25%). Preoperatively 68% had congestive heart failure and 72% had severe angina (CCS 3 or 4). A left main lesion was found in 26% of the cases. The mean number of grafts was 3.18 per patient. The left internal mammary artery (LIMA) was used on 107 patients (50.4%). Preoperative intraaortic balloon pump (IABP) was used on 32 patients (15%). Endarterectomy was performed on 53 patients (25%). The patients were followed for up to 58 months (mean 28.7). RESULTS: Twelve patients died in hospital (5.6%). Survival was 94%, 87%, 80% and 73% at 1, 2, 3 and 4 years respectively. Among the preoperative variables survival was negatively affected by chronic renal failure, older age, congestive heart failure, elevated pulmonary artery pressure and recent myocardial infarction, by means of multivariate analysis. Preoperative IABP support improved the operative mortality significantly (P=0.002). Use of LIMA did not have any influence on survival. CONCLUSION: CABG on patients with poor left ventricular function: (1). Can be performed with an acceptable mortality. (2). Mid term results are encouraging. (3). Preoperative IABP support improves the chance of survival.

Missed diagnosis of unruptured, huge left ventricular pseudoaneurysm.

We report a case of a huge left ventricular pseudoaneurysm following myocardial infarction. Early after myocardial infarction, the pseudoaneurysm was missed during the cardiac examination. The patient underwent coronary bypass surgery with endoaneurysmorraphy of the pseudoaneurysm, and made a satisfactory recovery.
