Cerebral Malperfusion

Surgery for acute aortic dissection is challenging, especially in cases of cerebral malperfusion. Should we perform only the aortic repair, or should we also reconstruct the arch vessels when they are severely affected by the disease process? Here we present a case of acute aortic dissection with multiple tears that involved the brachiocephalic artery and caused cerebral and right upper-extremity malperfusion. The patient successfully underwent complete replacement of the brachiocephalic artery and the aortic arch during deep hypothermic circulatory arrest, with antegrade cerebral protection. We have found this technique to be safe and reproducible for use in this group of patients.

Aortic Dissection Type A

The purpose of this case presentation is to present a simplified surgical technique when in a patient with acute aortic dissection type A (AAD), aortic arch, and ascending aorta is completely replaced without circulatory arrest. A 67-year old male was presented in our institution with severe chest and back pain at 12 h after the onset of the symptoms. Imaging studies by 3D contrast-enhanced thoracic computed tomography (CT-scan) and transesophageal echocardiography (TEE) revealed ascending aortic dissection towards the aortic arch, which was extending in the proximal descending aorta. We practiced emergency median sternotomy and established cardiopulmonary bypass (CBP) between the right atrium and the right femoral artery with successive cross-clamping of the ascending and descending aorta below the origin of the left subclavian artery (LSA). In normothermic condition without circulatory arrest and with antegrade cerebral perfusion, we replaced the ascending aorta and aortic arch with a four branched Dacron graft. Patient evolution was uneventful, and he was discharged, after fourteen days from the hospital. At a one-year follow-up, 3D CT-scan showed no residual dissection with a well-circulated lumen of the supra-aortic arteries. Using the described surgical approach, CPB was not interrupted, the brain was protected, and hypothermia was no used. This approach made these surgical procedures shorter, and known complications of hypothermia and circulatory arrest are avoided.Acute aortic dissection aortic type A, total arch replacement, normothermia

Before And After

Background: The objective of this study was to compare the incidence of severe systemic inflammatory response syndrome (sSIRS) after total aortic arch replacement between patients who underwent moderate hypothermic circulatory arrest (MHCA) and those who underwent deep hypothermic circulatory arrest (DHCA).Methods: At Fuwai Hospital, 600 patients who underwent total aortic arch replacement with MHCA or DHCA from January 2013 to December 2016 were consecutively enrolled and divided into DHCA (14.1–20.0°C) and MHCA (20.1–28.0°C) groups. Preliminary statistical analysis revealed that some baseline indicators differed between the two groups; therefore, propensity score matching (PSM) was used to balance the covariates. Post-operative sSIRS as the primary outcome was compared between the groups both before and after PSM.Results: A total of 275 (45.8%) patients underwent MHCA, and 325 (54.2%) patients underwent DHCA. After PSM analysis, a total of 191 matched pairs were obtained. The overall incidence of sSIRS was 27.3%. There was no significant difference in post-operative sSIRS between the MHCA group and the DHCA group in either the overall cohort or the PSM cohort (no-PSM: P = 0.188; PSM: P = 0.416); however, post-operative sSIRS was increased by ~4% in the DHCA group compared with the MHCA group in both the no-PSM and PSM cohorts (no-PSM: 29.5 vs. 24.7%; PSM: 29.3 vs. 25.1%). Both before and after PSM, the rates of gastrointestinal hemorrhage and pulmonary infection and post-operative length of stay were significantly increased in the DHCA group compared with the MHCA group (P < 0.05), and the remaining secondary outcomes were not significantly different between the groups.Conclusions: MHCA and DHCA are associated with comparable incidences of sSIRS in patients following total aortic arch replacement for type A aortic dissection. However, the MHCA group had a shorter cardiopulmonary bypass time, a shorter post-operative length of stay and lower pulmonary infection and gastrointestinal hemorrhage rates than the DHCA group. We cautiously recommend the use of MHCA for most total arch replacements in patients with type A aortic dissection.

Cent Change

The objective of this study was to compare retrograde with antegrade cerebral protection during acute aortic dissection repair using cerebral oximetry measurements. Fifty consecutive acute ascending aortic dissection repairs were analyzed. Cerebral oximetry data were collected for 41 of 50. Eight patients who had antegrade cerebral protection alone and 29 of 41 had retrograde cerebral protection alone. The per cent change in cerebral oximetry values during deep hypothermic circulatory arrest from baseline and from prearrest values was compared for the two groups using Student t test. The per cent change from baseline for the antegrade patients was: right 13.8 per cent and left -2.5 per cent; the per cent change from baseline for retrograde patients was: right 0.8 per cent and left 0.2 per cent ( P values 0.216 and 0.725, respectively). The per cent change from the prearrest value for the antegrade patients was: right -12 per cent and left -15 per cent; the per cent change from prearrest for retrograde patients was: right -15 per cent and left -16 per cent ( P values 0.514 and 0.956, respectively). No compelling evidence for an advantage to either antegrade or retrograde cerebral perfusion was detected. Further study with a focus on neurologic outcomes is warranted.

OBJECTIVE: This study aimed to retrospectively analyze the blood protective effect of autologous platelet separation in operations for acute aortic dissection. METHODS: A total of 130 patients with acute aortic dissection were enrolled into the present study. The average age of these patients was 52.962±10.5061 years old. These patients underwent the modified aortic arch replacement with the elephant trunk technique or endovascular aortic exclusion with covered stent. Among these patients, 68 patients who underwent autologous platelet separation were assigned to the platelet separation group, while the remaining patients were assigned to the control group. All operations were performed under deep hypothermic circulatory arrest. After anesthesia, 1–2 therapeutic doses of autologous platelets were isolated from patients in the platelet separation group, and these platelets were quickly infused back to these patients after heparin was neutralized by protamine at the end of the cardiopulmonary bypass. The preoperative and postoperative indexes in these two groups were compared. RESULTS: There were no statistically significant differences in age, gender, smoking history, drinking history and hypertension history between these two groups. Compared with controls, the transfusion volume of allogeneic platelets in the perioperative period significantly decreased in the platelet separation group (1.919±1.6226 vs. 0.794±1.1789, P < #x003C;< #x200A;0.05), and the use rate of allogeneic platelets also significantly decreased (74.19% vs. 45.59%, P < #x003C;< #x200A;0.05). CONCLUSION: The intraoperative auto transfusion of platelets significantly reduced the volume of allogeneic platelet transfusion after the operation for aortic dissection, which has a significant blood protective effect.

Optimal Timing

Background: There are no guidelines for the optimal timing of surgery (emergency vs. delayed) for ascending aortic dissection with acute ischemic stroke. We retrospectively compared the prognoses and radiological and clinical findings for concomitant aortic dissection and ischemic stroke in a series of case reports. Case presentation: Three patients presented with left hemiparesis. Patient 1 underwent surgery for acute aortic dissection without treatment for acute ischemic stroke. In Patient 2, emergency stenting could not be performed due to cardiac tamponade and hypotension. Therefore, emergency acute aortic dissection surgery was performed. Patient 3 underwent emergency right common carotid artery stenting followed by surgery for acute aortic dissection. Brain perfusion computed tomography angiography (CTA) was performed to diagnose severe stenosis of the right common carotid artery or occlusion concomitant with acute aortic dissection involving the aortic arch with a cerebral perfusion mismatch in all the patients. Patient 3 had postoperative local cerebral infarction, whereas patients 1 and 2 (without stent insertion) had extensive postoperative cerebral infarction. Conclusion: Patient 3 showed a better prognosis than patients without stent treatment. We suggest that perfusion CTA of the aortic arch in suspected acute ischemic stroke can facilitate early diagnosis and prompt treatment in similar patients.
