Antegrade cerebral perfusion: A review of its current application

WOS:000612350500001PubMed: 33768974The technique of antegrade cerebral perfusion has been adopted by many aortic surgery centers as the routine method of brain protection with some variations in its implementation. These variations stem from the issues with regard to the perfusion pressure, flow, temperature, pH management, hematocrit value, cannulation sites, and unilateral versus bilateral application. in this review, the prespecified issues were discussed and some recommendations about the implementation of antegrade cerebral perfusion were given

The impact of oral anticoagulation on false lumen patency in acute type A aortic dissections

WOS: 000439420000001Background: In this study, the effect of postoperative oral anticoagulation on the false lumen patency of the distal aorta in patients with acute type A aortic dissection was investigated. Methods: Forty-one patients (32 male, 9 female; mean age 56.8 +/- 13.6 years; range, 30 to 84 years) who were diagnosed with acute type A aortic dissection and underwent surgical treatment in our clinic, and whose entire data of both control computed tomographic assessments and all postoperative follow-up visits could be accessed were enrolled. The patients were divided into two groups according to the type of surgical intervention that was performed. Computed tomography imaging of the patients were scanned and false lumen patency rates were evaluated. Besides oral anticoagulation, preoperative, intraoperative, and postoperative risk factors that may have affected false lumen patency secondary to acute type A aortic dissection were evaluated and statistically analyzed. Results: Twenty-one patients (51.2%) had concomitant hypertension. Thirty five (85.4%) of the patients had the main symptom of angina. Sixteen patients (39%) in Group 1 underwent ascending aortic replacement combined with aortic valve replacement (Bentall procedure); while 25 patients (61%) in Group 2 underwent isolated ascending aortic replacement. Mean follow-up was 43.9 +/- 26.3 (range: 5-120) months. No statistically significant difference was found between the study subgroups in any of the operation parameters except for cardiopulmonary bypass time (p=0.035) and cross-clamp time (p=0.002). Evaluation of the control contrast-enhanced tomographic imaging of the patients showed false lumen patency in the thorax in 34 patients (82.9%) and in the abdominal region in 33 patients (80.5%). When analyzing subgroups according to the type of surgical procedure, or indirectly anticoagulant use, no statistically significant difference was found in false lumen patency prevalence between the thoracic and abdominal groups (p=0.534 and p=0.922). Conclusion: No potential effect of postoperative anticoagulation on false lumen patency was found in cases with acute type A aortic dissection

Effects of thoracic and hiatal clamping in repair of ruptured abdominal aortic aneurysms

WOS: 000254207100004PubMed ID: 17512162The purpose of this study was to determine the effects of hiatal and thoracic clamping on postoperative outcome and morbidity and factors affecting mortality and morbidity. The records of 102 patients who had undergone ruptured abdominal aortic aneurysm repair between 1993 and 2005 were evaluated retrospectively. Hiatal clamping and thoracic clamping were performed in 72 patients and 30 patients, respectively. Postoperative complications and survival were evaluated comparatively between the two groups by univariate and multivariate statistical analyses. Overall mortality and hospital mortality rates were 63 ( 61.8%) and 24 ( 23.5%) patients, respectively; and there was no difference between the two groups. Postoperative respiratory complications, gastrointestinal complications, and blood requirement were higher in the thoracic clamping group. Preoperative shock and renal ischemia time (> 30 min) were found to be significant predictors of hospital mortality. Postoperative renal failure was the only independent postoperative predictor of mortality. In the follow-up period, cardiac event was an independent predictor of late mortality. If hospital mortalities were excluded, 5-year and 10-year cumulative survivals were 57.82 +/- 5.85% and 38.16 +/- 6.97%, respectively. Cross-clamp level did not have a significant effect on long-term survival. Although both thoracic and hiatal clamping had no effect on mortality, postoperative respiratory complications, blood requirement, and intestinal ischemia were more pronounced in patients operated with thoracic clamping. Hiatal clamping is preferable for a safe postoperative period
