Double arterial perfusion strategy for extensive thoracic aortic surgery to avoid lower body hypothermic circulatory arrest

OBJECTIVE To analyse our results of using a double arterial perfusion strategy to avoid lower body hypothermic circulatory arrest after extensive thoracic aortic surgery. METHODS We analysed the intra- and perioperative courses of 10 patients (median age 58 years, median logistic EuroSCORE 14.6) who underwent extensive thoracic aortic surgery with a double arterial perfusion strategy. The main goal of double arterial perfusion is to separate myocardial and supra-aortic from systemic perfusion. Aortic repair starts at the most distal level of the descending aorta, followed by reinsertion of the supra-aortic vessels, and ends with completion of the proximal anastomosis or by any kind of root repair as needed. RESULTS Seven of 10 patients had prior surgery of the thoracic aorta. Indications for surgery were post-dissection aneurysm in 4 patients, true aneurysm in 3, anastomotic aneurysms in 2 and Type B aortic dissection with pseudo-coarctation in 1. Surgical access was performed through median sternotomy with left hemi-clamshell extension in all cases. There was no in-hospital mortality, but perioperative neurological symptoms occurred in 2 patients. These 2 patients developed delayed stroke (after awaking) after an initial uneventful clinical course, and in 1 of them, neurological symptoms resolved completely during follow-up. The median follow-up was 7 (±13) months. There was no death and no need for additional redo surgery during this observational period. CONCLUSIONS Extensive surgery of the thoracic aorta using a double arterial perfusion technique in order to avoid lower body hypothermic circulatory arrest is an attractive option. Further refinements of this technique may enable the safe and effective simultaneous multisegmental treatment of thoracic aortic pathology in patients who would otherwise have to undergo a two-step surgical approach.

The future of aortic surgery in Europe

At least every ten years, each specialty should reflect upon its past, its present and its future, in order to be able to reconfirm the direction in which it is headed, to adopt suggestions from inside and outside and, consequently, to improve. As such, the aim of this manuscript is to provide the interested reader with an overview of how aortic surgery and (perhaps more accurately) aortic medicine has evolved in Europe, and its present standing; also to provide a glimpse into the future, trying to disseminate the thoughts of a group of people actively involved in the development of aortic medicine in Europe, namely the Vascular Domain of the European Association of Cardio-Thoracic Surgery (EACTS).

Should aortic arch replacement be performed during initial surgery for aortic root aneurysm in patients with Marfan syndrome?

OBJECTIVES: The aim of this study was to investigate whether total arch replacement (TAR) during initial surgery for root aneurysm should be routinely performed in patients with Marfan syndrome (MFS). METHODS: Retrospective analysis of 94 consecutive MFS patients fulfilling Ghent criteria who underwent 148 aortic surgeries and were followed at this institution during the past 16 years. RESULTS: The mean follow-up interval was 8.8 ± 7 years. Initial presentation was acute aortic dissection (AAD) in 35% of patients (76% Type A and 24% Type B) and aneurismal disease in 65%. TAR was performed in 8% of patients during initial surgery for AAD (otherwise a hemi-arch replacement was performed) and 1.6% in elective root repair. Secondary TAR had to be performed in only 3% of patients without, but in 33% following AAD (33% Type A and 33% Type B; P = 0.0001). Thirty-day, 6-month, 1-year and overall mortalities were 3.2, 5.3, 6.4 and 11.7%, respectively. Operative and 30-day mortalities in secondary aortic arch replacement were zero. Secondary TAR after AAD did not increase the need for the replacement of the entire thoracoabdominal aorta during follow-up compared with patients without secondary TAR (37 vs 40%, P = 1.0). CONCLUSIONS: MFS patients undergoing elective root repair have small risk of reinterventions on the aortic arch, and primary prophylactic replacement does not seem to be justified. In patients with AAD, the need for reinterventions is precipitated by the dissection itself and not by limiting the procedure to the hemi-arch replacement in the emergency setting. Limiting surgery to the aortic root, ascending aorta and proximal aortic arch is associated with low mortality in MFS patients presenting with AAD.

Important excess morbidity due to upper airway anomalies in the perioperative course in infant cardiac surgery

BACKGROUND: The study aimed at defining the excess morbidity or mortality caused by an additional airway malformation in children with congenital heart disease requiring surgery. METHODS: All patients requiring surgery for heart disease during an 8-year period ending in 2003 who had an associated upper airway malformation were retrospectively studied. All patients were seen in 2004 for a prospective follow-up examination. RESULTS: Eleven patients with upper airway anomalies were identified (tracheobronchial malacia in 6 patients, long-segment tracheal stenosis in 3, and bilateral vocal cord paralysis and tracheal hemangioma in 1 patient each). They accounted for 1.5% of the entire cardiac surgical load of 764 patients. In 5 infants, the airway anomaly was diagnosed before cardiac repair, in 6 patients thereafter. Diagnosis was made by bronchoscopy in all patients, by additional bronchography in 2. Failure of rapid postoperative extubation was the most common finding. Airway management was surgical in 2 and conservative in 8 patients, 1 newborn having been denied therapy because of the severity of airway hypoplasia. Compared with patients with isolated cardiac disease, those with additional airway anomalies had significantly longer duration of postoperative mechanical ventilation (median, 24 days versus 3), perioperative hospitalization (median, 72 days versus 11) and total number of days of hospitalization during the first year of life (median, 104 days versus 14). After a maximum follow-up of 8 years (median, 37 months) only 3 of 10 surviving patients remained symptomatic owing to the airway malformation. CONCLUSIONS: Upper airway anomalies accompanying heart disease in infancy resulted in a significant prolongation of perioperative intensive care and hospital stay, as well as duration of mechanical ventilation. Failure of early postoperative extubation was the leading symptom.
