Objective To investigate and compare the different surgical strategies for typeⅠpulmonary atresia with ventricular septum defect (PA/VSD) and the outcomes of postoperative prognosis in early stage. Methods We retrospectively analyzed the clinical data of 61 typeⅠPA/VSD patients (40 males, 21 females) with a median age of 249 days (range, 13 days-19 years) in Guangdong Cardiovascular Institute from January 2005 to December 2014 . Among them, 42 patients (27 males, 15 females) with a median age of 11.11 months, ranging from 0.80–211.70 months received radical surgery as a radical surgery group. And 19 patients (13 males, 6 females) with a median age of 2.96 months, ranging from 0.47–161.83 months underwent palliative surgery as a palliative surgery group. We compared the two surgeries and their early outcomes. Results The mean postoperative oxygen saturation was 88.08%±9.64%, which showed significant improvement compared with preoperative oxygen saturation of 74.08%±12.99% (P＜0.05). Patients in the palliative surgery group had a lower body temperature during cardiopulmonary bypass and more respiratory complications than those in the radical surgery group (24.69 °C±3.11 °C vs. 27.18 °C±2.10 °C). Conclusion Both radical and palliative surgeries are good for the increase of pulmonary blood volume and the development of pulmonary vessels. Surgeons must pay more attention to choosing radical surgery for the babies, which is only considerd for those with well developed pulmonary arteries.
Surgical intervention for chronic thoracoabdominal aortic dissecting aneurysms (cTAADA) is regarded as one of the most challenging procedures in the field of vascular surgery. For nearly six decades, open repair predominantly utilizing prosthetic grafts has been the treatment of choice for cTAADA. With advances in minimally invasive endovascular technologies, two novel surgical approaches have emerged: total endovascular stent-graft repair and hybrid procedures combining retrograde debranching of visceral arteries with endovascular stent-graft repair (abbreviated as hybrid procedure). Although total endovascular stent-graft repair offers reduced trauma and quicker recovery, limitations persist in clinical application due to hostile anatomical requirements of the aorta, high costs, and the lack of universally available stent-graft products. Hybrid repair, integrating the minimally invasive ethos of endovascular repair with visceral artery debranching techniques, has increasingly become a significant surgical modality for managing thoracoabdominal aneurysms, especially in cases unsuitable for open surgery or total endovascular treatment due to anatomical constraints such as aortic tortuosity or narrow true lumens in dissections. Recent enhancements in hybrid surgical approaches include ongoing optimization of visceral artery reconstruction strategies based on hemodynamic analyses, and exploration of the comparative benefits of staged versus concurrent surgical interventions.
