Managing Emergency Hypertension in Aortic Dissection and Aortic Aneurysm Surgery

JOURNAL OF CARDIAC SURGERY, Issue 2006
Ali Khoynezhad M.D.
Similar development has occurred in regard to the treatment of thoracic aortic aneurysms. Treatment options are medical, surgical, or endovascular. Aortic dissection always presents as a hypertensive emergency and requires parenteral antihypertensive agents to control blood pressure (BP) and prevent target organ damage. Diligent control of BP is of utmost importance in order to stop the progression of dissection with possible aortic branch malperfusion. Treatment for hypertensive emergency begins in the intensive care unit and continues during and after surgery. Improved surgical techniques as well as newer, safer agents that reduce BP to acceptable levels have reduced the risk of mortality and improved prognosis in the postoperative period. Nevertheless, mortality rates remain high, and successful management of aortic dissection and aortic aneurysm still poses a clinical challenge. [source]

Pilot Study of Sexual Dysfunction Following Abdominal Aortic Aneurysm Surgery

THE JOURNAL OF SEXUAL MEDICINE, Issue 4ii 2007
MRCSI, Vincent Koo MBBCh
ABSTRACT Introduction., The complication of sexual dysfunction as a quality of life (QoL) component after abdominal aortic aneurysm (AAA) surgery in men is poorly studied. Aims., To investigate the prevalence of sexual dysfunction and to highlight the importance of discussing this issue with patients undergoing AAA repair. Main Outcome Measures., The self-reported sexual dysfunction prevalence pre- and postoperatively, the effects on sexual QoL, and the postoperative Sexual Health Inventory for Men (SHIM) scores. Methods., Between April 1999 and July 2002, a questionnaire-based study, including the SHIM, was conducted on male patients 1,2 years after their elective open (EO) and rupture open (RO) or endovascular repair (EVAR) AAA repair. Demographics, risk factors for sexual dysfunction, sexual history, and postoperative sexual QoL data were obtained. Results., Out of 142 alive male patients surveyed, 56 (40%) patients responded (26 EO, 21 EVAR, and 9 RO repair). The mean age was 69, 73, and 70 years, respectively, and 65%, 66%, and 66%, respectively, admitted to be sexually active postoperatively. The self-reported sexual dysfunction prevalence preoperatively was 27% (EO), 63% (EVAR), and 45% (RO); and postoperatively was 58%, 76%, and 67%, respectively. Detection using SHIM was higher at 70%, 95%, and 78%, respectively. There was a significantly greater increase in the postoperative prevalence of sexual dysfunction in the EO group than in the EVAR group (P < 0.05, ,2). The sexual QoL was worsened postoperatively in all groups: 53% (EO), 75% (EVAR), and 50% (RO); but only one-third of EO and EVAR patients, and none in RO patients, would seek treatment for their sexual dysfunction. Conclusion., There was a negative impact on the sexual QoL in all groups after surgery, and a significantly higher proportion of patients experienced deterioration in sexual QoL following EO surgical repair. Our results demonstrate the need for a prospective study. Koo V, Lau L, McKinley A, Blair P, and Hood J. Pilot study of sexual dysfunction following abdominal aortic aneurysm surgery.

Noninvasive Control of Adequate Cerebral Oxygenation During Low-Flow Antegrade Selective Cerebral Perfusion on Adults and Infants in the Aortic Arch Surgery

JOURNAL OF CARDIAC SURGERY, Issue 5 2008
Álvaro Rubio M.D.
Background: Aortic arch repair techniques using low-flow antegrade selective cerebral perfusion have been standardized to a certain degree. However, some of the often-stated beneficial effects have never been proven. Especially, the existence of an adequate continuous flow in both cerebral hemispheres during the surgical procedure still remains unclear as the monitoring of an effective perfusion remains a nonstandardized technique. Methods: Seventeen patients underwent surgical reconstruction of the aortic arch due to aortic aneurysm surgery (adult group n = 8 patients) or of the hypoplastic aortic arch due to hypoplastic left heart syndrome (HLHS) or aortic coarctation (infant group n = 9 patients) under general anesthesia and mild hypothermia (adult group 28 °C; infant group 25 °C). Mean weights were 92.75 ± 14.00 kg and 4.29 ± 1.32 kg, and mean ages were 58.25 ± 10.19 years and 55.67 ± 51.11 days in the adult group and the infant group, respectively. The cerebral O2 saturation measurement was performed by continuous plotting of the somatic reflectance oximetry of the frontal regional tissue on both cerebral hemispheres (rSO2, INVOS®; Somanetics Corporation, Troy, MI, USA). Results: During low-flow antegrade perfusion via innominate artery, continuous plots with similar values of O2 saturation (rSO2) in both cerebral hemispheres were observed, whereas a decrease in the rSO2 values below the desaturation threshold correlated with a displacement or an incorrect positioning of the arterial cannula in the right subclavian artery. Conclusions: Continuous monitorization of the cerebral O2 saturation during aortic arch surgery in adults and infants is a feasible technique to control an adequate cannula positioning and to optimize clinical outcomes avoiding neurological complications related to cerebral malperfusion.

Effects of levosimendan on indocyanine green plasma disappearance rate and the gastric mucosal,arterial pCO2 gradient in abdominal aortic aneurysm surgery

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2008
H. LEPPIKANGAS
Background: Levosimendan has a dual mechanism of action: it improves myocardial contractility and causes vasodilatation without increasing myocardial oxygen demand. In a laboratory setting, it selectively increases gastric mucosal oxygenation in particular and splanchnic perfusion in general. The aim of our study was to describe the effects of levosimendan on systemic and splanchnic circulation during and after abdominal aortic surgery. Methods: Twenty abdominal aortic aneurysm surgery patients were randomized to receive either levosimendan (n=10) or placebo (n=10) in a double-blinded manner. Both the mode of anaesthesia and the surgical procedures were performed according to the local guidelines. Automatic gas tonometry was used to measure the gastric mucosal partial pressure of carbon dioxide. Systemic indocyanine green clearance plasma disappearance rate (ICG-PDR) was used to estimate the total splanchnic blood flow. Results: The immediate post-operative recovery was uneventful in the two groups with a comparable, overnight length of stay in the intensive care unit. Cumulative doses of additional vasoactive drugs were comparable between the groups, with a tendency towards a higher cumulative dose of noradrenaline in the levosimendan group. After aortic clamping, the cardiac index was higher [4(3.8,4.7) l/min/m2 vs. 2.6(2.3,3.6) l/min/m2; P<0.05] and the gastric mucosal,arterial pCO2 gradient was lower in levosimendan-treated patients [0.9(0.6,1.2) kPa vs. 1.7(1.2,2.1) kPa; (P<0.05)]. However, the total splanchnic blood flow, estimated by ICG-PDR, was comparable [29(21,29)% vs. 20(19,25)%; NS]. Organ dysfunction scores (sequential organ dysfunction assessment) were similar between the groups on the fifth post-operative day. Conclusion: Levosimendan favours gastric perfusion but appears not to have a major effect on total splanchnic perfusion in patients undergoing an elective aortic aneurysm operation. [source]

Pilot Study of Sexual Dysfunction Following Abdominal Aortic Aneurysm Surgery

How safe is open abdominal aortic aneurysm surgery for octogenarians in New Zealand?

ANZ JOURNAL OF SURGERY, Issue 5 2009
Ian A. Thomson
Abstract Background:, Abdominal aortic aneurysm (AAA) is an important cause of mortality for the aged, a group that has been denied surgery in the past for fear of peri-operative mortality. Is this attitude still justified? Methods:, Analysis of prospectively gathered data from a vascular database. Results:, 10.9% of all open AAA operations were in patients older than 79 years with an 8% mortality cate compared to 3% for younger patients. For fit elderly patients with ASA scores less than 3, mortality was just under 4%. Renal failure and wound dehiscence were more common in the elderly. Conclusion:, When endovascular repair is not possible in a fit elderly patient, open surgery can be performed with acceptable results. [source]

Mid-term survival after abdominal aortic aneurysm surgery predicted by cardiopulmonary exercise testing

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 8 2007
J. Carlisle
Background: Cardiopulmonary exercise (CPX) testing measures how efficiently subjects meet increased metabolic demand. This study aimed to determine whether preoperative CPX testing predicted postoperative survival following elective abdominal aortic aneurysm (AAA) repair. Methods: Some 130 patients had CPX testing before elective open AAA repair. Additional preoperative, operative and postoperative variables were recorded prospectively. Median follow-up was 35 months. The correlation of variables with survival was assessed by single and multiple regression analyses. Results: CPX testing identified 30 of 130 patients who had been unfit before surgery. Two years after surgery the Kaplan,Meier survival estimate was 55 per cent for the 30 unfit patients, compared with 97 per cent for the 100 fit patients. The absolute difference in survival between these two groups at 2 years was 42 (95 per cent confidence interval 18 to 65) per cent (P < 0·001). Conclusion: Preoperative CPX testing, combined with simple co-morbidity scoring, identified patients unlikely to survive in the mid-term, even after successful AAA repair.

Impact of renal dysfunction on operative mortality following endovascular abdominal aortic aneurysm surgery,

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 2 2007
R. G. Statius van Eps
Background: Preoperative renal dysfunction is a significant risk factor for death after open abdominal aortic aneurysm repair. The aim of this study was to determine whether renal dysfunction also affected mortality after endovascular aneurysm repair. Methods: Patients from the EUROSTAR registry were stratified into two groups: 4198 with normal renal function (creatinine less than 133 µmol/ml) and 969 with renal dysfunction (serum creatinine more than 133 µmol/ml). Patient characteristics and postoperative complications in the two groups were compared and the effect of renal dysfunction on operative mortality was analysed by multivariable regression models. Results: Patients with renal dysfunction had significantly more co-morbidities, including cardiac and pulmonary impairment. Thirty-day mortality was significantly higher in the group with renal dysfunction (6·2 versus 2·0 per cent; P < 0·001). A significant increase in mortality (5·5 per cent) was also seen in patients with moderate renal dysfunction (serum creatinine 133,265 µmol/ml). After adjustment for age and other risk factors, renal dysfunction was still an independent risk factor for 30-day mortality (odds ratio 2·3, 95 per cent confidence interval 1·6 to 3·3; P < 0·001). Conclusion: Renal dysfunction was a significant and independent risk factor for death after endovascular aneurysm repair. Copyright © 2006 British Journal of Surgery Society Ltd.

Impact of early surgery after aneurysmal subarachnoid haemorrhage

ACTA NEUROLOGICA SCANDINAVICA, Issue 2 2009
M. Van Der Jagt
Objectives,,, To investigate the effect of early aneurysm surgery (<72 h) on outcome in patients with subarachnoid haemorrhage (SAH). Materials and methods,,, We studied two consecutive series of patients with aneurysmal SAH [postponed surgery (PS) cohort, n = 118, 1989,1992: surgery was planned on day 12 and early surgery (ES) cohort, n = 85, 1996,1998: ES was performed only in patients with Glasgow Coma Scale (GCS) >13]. We used multivariable logistic regression analysis to assess outcome at 3 months. Results,,, Favourable outcome (Glasgow Outcome Scale 4 or 5) was similar in both cohorts. Cerebral ischemia occurred significantly more often in the ES cohort. The occurrence of rebleeds was similar in both cohorts. External cerebrospinal fluid (CSF) drainage was performed more often in the ES cohort (51% vs 19%). Patients with cisternal sum score (CSS) of subarachnoid blood <15 on admission [adjusted odds ratio (OR) for favourable outcome: 6.4, 95% confidence interval (CI) 1.0,39.8] and patients with both CSS <15 and GCS > 12 on admission benefited from the strategy including ES (OR 10.5, 95% CI 1.1,99.4). Conclusions,,, Our results support the widely adopted practice of ES in good-grade SAH patients. [source]
