Objective To compare the short and mid-term outcomes of open surgery and hybrid technique for the treatment of complex type B aortic dissection (AD). Methods A total of 45 patients (37 acute AD and 8 chronic AD) with complex type B AD were admitted to Nanjing First Hospital from January 2012 to June 2016, including 37 males and 8 females. All patients were confirmed by computed tomography angiography (CTA), and ultrasonic cardiogram (UCG) to rule out valvular diseases, aortic root and ascending aorta lesion, and pericardial effusion. According to different treatments, patients were divided into two groups: the open surgery group (OS group) with a total of 25 patients (20 males, 5 females, a mean age of 50.16±10.87 years); the hybrid technique group (HT group) with a total 20 patients (18 males, 2 females, mean age of 51.31±8.11 years). The short and mid-term outcomes of open surgery and hybrid technique for the treatment of complex type B AD were compared. Results All the patients were discharged successfully. There was no death, cognitive impairment, cerebral infarction, hemiplegia, paraplegia, coma and other neurological complications in both groups. In the OS group, one patient suffered acute kidney injury and received renal replacement therapy (RRT), whose renal function was returned to normal prior to discharge; one patient was transferred to ICU again owing to pericardial effusion, respiratory failure and lung infection; one patient underwent debridement surgery because of postoprative sternal dehiscence. In the HT group, one patient with recurrent chest pain five days after endovascular aortic repair, whose CTA showed hematoma of aortic arch and ascending aorta caused by reverse tear, underwent Sun’s procedure immediately. All patients received CTA examination three months after operation in outpatient room. In the OS Group, the tear of AD was closed well by stent-graft and no leakage or shunt was detected in CTA. The rate of thrombosis formation in thoracic aortic false lumen was 100.0%. Meanwhile, in the HT Group, there was one patient with type Ⅱ leakage and the rate of thrombosis formation in thoracic aortic false lumen was 94.7%. Conclusion For complex type B AD without optimal "landing zone" in descending aorta, open surgery is recommended as the first choice for experienced team because of its less costs and perfect results; hybrid technique which can achieve quicker recovery with less surgical trauma still has serious complications such as leakage, reverse tear, and so on.
Atrial fibrillation (AF) is difficult to cure for its complex etiology and long disease duration. Heart failure, sudden death and stroke are the main causes for consequent high mortality and morbidity. In recent years, minimally invasive surgery has made rapid progress, not only improved treatment efficiency of traditional Cox Maze procedure but also massively reduced surgical injuries, and has become a preferred treatment strategy for lone AF. Minimally invasive surgery and catheter ablation complement each other, and are likely to open up a new prospect of AF treatment.
Objective To evaluate the importance of "one-stop" hybrid operating room in the individualized treatment of aortic pathology. Method We retrospectively analyzed the clinical data of 247 patients of aortic pathology who were operated in the hybrid operating room in our hospital from January 2013 through December 2014. There were 193 males and 54 females at age of 24-83(54±12) years. Results Thoracic or abdominal endovascular aortic repair (TEVAR/EVAR) was applied in 132 patients, including 122 simple patients and 10 complexes. Fenestrated TEVAR was applied in 61 patients. Hybrid operation was done in 54 patients. Perioperative death occurred in 9 patients (3.6%). Perioperative complication rate was 11.7% (29/247) . The patients were followed up for one year. During follow-up, five patients were dead. The one-year survival rate was 98.0% (242/247) . Conclusions "One-stop" individualized treatment of aortic pathology shows its advantage, yet long-term result still needs to be followed up.
Objective To analyze the clinical effect of hybrid surgery on complex type B aortic dissection in 5 years. Methods A retrospective analysis of 47 patients with complex type B aortic dissection in the Central Hospital of Wuhan affiliated to Tongji Medical College of Huazhong University of Science and Technology from 2014 to 2017 was conducted, including 42 males and 5 females with an average age of 54.9±11.2 years. Twenty-one patients underwent the left common carotid artery to the left subclavian artery bypass (a bypass group), and 26 patients underwent the left common carotid artery to the left subclavian artery transposition (a transposition group). Results All patients accepted hybrid surgery successfully. There was no statistical difference in arterial occlusion time or intraoperative blood loss between the two groups (P＞0.05). The 5-year follow-up rate was 100.0% (47/47). During the follow-up period, 12 (25.5%) patients developed complications, including 5 (10.6%) patients of endoleak, 5 (10.6%) patients of hoarseness, 2 (4.3%) patients of stroke/dizziness. There was no patient of left upper limb weakness, paraplegia or retrograde aotic dissection. The reconstructed left subclavian artery remained patent in 46 (97.9%) patients. The overall 5-year survival rate was 100.0%. Conclusion The long-term therapeutic outcome of hybrid surgery for the treatment of complex type B aortic dissection is satisfying. In 5 years, the rebuilt left subclavian artery has a remarkable patency rate. Endoleak and hoarseness are the most common surgical complications.
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.
Aortic arch disease is one of the research hotspots and treatment difficulties in the field of aorta, including aortic arch aneurysms, pseudoaneurysm, ulcer, dissection and intramural hematoma. By summarizing the clinical data of the vascular surgery center of Fuwai Hospital of Chinese Academy of Medical Sciences in the past five years and combining with the latest theories of the cutting-edge development of aortic surgery, the authors proposed the "HENDO" concept, including using hybrid technique (H), endovascular repair (Endo) and open surgery (O), properly to treat aortic arch pathologies individually. The authors advocated the establishment of HENDO team and cooperation mechanism in large aortic centers, to eliminate technical shortcomings of a single surgeon by fully mastering the three main technology clusters by teamwork. Accordingly, the best treatment for each patient can be administrated and the survival rate and quality of life can be improved eventually.
Kommerell's diverticulum is a rare congenital abnormal aortic development. The diverticulum can occur in both left and right aortic arches, from which an aberrant subclavian artery rises to the contralateral side. Only a small number of patients with Kommerell's diverticulum present symptoms. Dysphagia, dyspnea, chest discomfort and upper extremity blood pressure difference are common in adult patients. The risk of aortic dissection or aortic aneurysm rupture is higher in such patients than that in patients with normal aorta. Early surgical intervention is recommended to improve the prognosis. Treatment options include open surgical repair, hybrid operation and total endovascular repair. The choice of surgical method depends on the specific anatomy of patients, the patients' state and the preference of surgeons. This paper reviewed and summarized the surgical methods and early results of the treatment of Kommerell's diverticulum reported in the literature from 2015 to 2020.
ObjectiveTo evaluate the results of a hybrid procedure for treating Stanford type B1C aortic dissection.MethodsIn our center, 49 patients with Stanford type B1C aortic dissection underwent supra-arch branch vessel bypass and thoracic endovascular aortic repair (TEVAR) from December 2013 to December 2017. There were 33 males and 16 females with an average age of 60.4±5.5 years. Left common carotid artery to left subclavian artery bypass (n=29), right common carotid artery to left common carotid artery and left subclavian artery bypass (n=18), left common carotid artery to left subclavian artery and right common carotid artery to right subclavian artery bypass (n=2) were performed.ResultsEarly mortality rate was 2.0% (1/49). Forty-eight patients survived postoperatively. The follow-up rate was 100.0% (48/48). The patients were followed up for 6 to 47 (26.8±11.9) months postoperatively. Chest pain relapsed in one patient 8 months after the operation. The whole aorta CTA showed type A1S aortic dissection in one patient 6 months after the operation, and the re-operation was satisfactory. There was no endoleak or paraplegia.ConclusionInitial results suggest that the one-stage hybrid procedure is a suitable therapeutic option for type B1C aortic dissection.
