ObjectiveTo evaluate the short-and long-term results of hybrid procedures in the treatment for aortic arch lesions. MethodsFrom October 2002 to March 2011, 28 patients with thoracic aortic aneurysms or dissections involving the aortic arch were treated with hybrid endovascular treatment in our center. Twenty-two males and 6 females were in the series. The mean age of the patients was 68 years old. Of 28 patients, 15 were atherosclerotic thoracic aortic aneurysms and 13 were thoracic aortic dissection. Follow-up protocol consisted of computed tomography (CT) angiograms or ultrasound was performed in 3, 6, and 12 months, and annually thereafter. The main goal was to evaluate the operative mortality, morbidity, and the longterm survival of these patients. ResultsHybrid procedures included 12 totalarch transpositions, 3 left common carotid artery (LCCA)left subclavian artery (LSA) bypass, 11 right common carotid artery (RCCA)LCCA-LSA bypass, 2 RCCA-LCCA bypass. The technical success rate was 92.9% (26/28). The complications occurred in 10 patients (35.7%). Operative mortality was 7.1% (2/28). The apoplexia rate was 7.1% (2/28). The time of followup was (36±3) months. The patency rates of 1-year, 3-year, and 5-year were 100%, 92.9% (26/28), and 85.7% (24/28), respectively. The survival rates of 1-year, 3-year, and 5-year were 89.3% (25/28), 71.4% (20/28), and 60.7% (17/28), respectively. ConclusionsThe short-and long-term results with hybrid procedures in the treatment for aortic arch diseases are satisfactory. Further reducing the complications is the key to increase the survival rate.
ObjectiveTo explore the single-center experience of hybrid therapy in treatment of Stanford type A aortic dissection, and to make a comparison of the clinical results of this hybrid therapy with total arch replacement surgery in the same period.MethodsFrom March 2017 to April 2020, 272 patients with Stanford type A aortic dissection underwent surgical treatment in our center, including 147 patients (126 males and 21 females) who received the aortic arch surgery. Among them, 106 patients underwent replacement of ascending aorta+aortic arch+stent trunk (total arch replacement group), while 41 patients underwent one-stop compound total arch type Ⅱ hybrid surgery (compound total arch replacement group). We tried to identify whether hybrid surgery really simplified total arch replacement surgery of the aortic dissection by comparing the operative mortality, postoperative complication rate, operative time, extracorporeal circulation time, etc.ResultsThere was no statistical difference in preoperative clinical data or death rate between the two groups. However, blood transfusion (6.74±7.35 U vs. 4.65±6.87 U, P<0.05), postoperative respiratory insufficiency [16 (15.09%) vs. 2 (4.88%), P<0.05], and apoplexy [3 (2.83%) vs. 0, P<0.05], paraplegia [2 (1.89%) vs. 0, P<0.05], in the compound total arch replacement group was significantly better than those of the total arch replacement group. The compound total arch replacement group did not shorten the total operation time, but it was significantly better in terms of extracorporeal circulation time (175.50±55.70 min vs. 129.70±48.80 min, P<0.05), aortic block time (103.10±23.70 min vs. 49.70±30.10 min, P<0.05), and the time of stopping the circulation or avoiding stopping the circulation (32.10±7.20 min vs. 0 min, P<0.05). The postoperative mechanical ventilation time was shorter in the compound total arch group (62.60±31.70 h vs. 41.30±32.60 h, P<0.05), and the time of staying in ICU (124.50±61.50 h vs. 63.40±71.20 h, P<0.05) and the postoperative hospital stay (13.50±11.20 d vs. 9.20±7.20 d, P<0.05) were significantly shorter than those in the total replacement group. A total of 138 patients were followed up for 6-38 (15.8±6.4) months. There was no statistical difference in one-year mortality or three-year mortality (P>0.05).ConclusionHybrid surgery shortens extracorporeal circulation time, while reduces or avoids the time of deep hypothermia circulatory arrest, the incidence of complications and the time of hospital stay. In conclusions, hybrid surgery simplifies the arch management of acute Stanford type A aortic dissection.
Objective To assess the efficacy and safety of ascending aorta banding technique combined with typeⅠhybrid aortic arch repair for the aortic arch diseases. Methods The clinical data of patients undergoing ascending aorta banding technique combined with type Ⅰ hybrid arch repair for aortic arch diseases from March 2019 to March 2022 in Beijing Anzhen Hospital were retrospectively analyzed. The technical success, perioperative complications and follow-up results were evaluated. Results A total of 44 patients were collected, including 35 males and 9 females, with a median age of 63.0 (57.5, 64.6) years. The average EuroSCORE Ⅱ score was 8.4%±0.7%. The technical success rate was 100.0%. All patients did not have retrograde type A aortic dissection and endoleaks. One patient died of multiple organ failure 5 days after operation, the in-hospital mortality rate was 2.3%, and the remaining 43 patients survived and were discharged from hospital. The median follow-up period was 14.5 (6-42) months with a follow-up rate of 100.0%. One patient with spinal cord injury died 2 years after hospital discharge. One patient underwent thoracic endovascular aortic repair at postoperative 3 months due to new entry tears near to the distal end of the stent. Conclusion Ascending aorta banding combined with typeⅠhybrid arch repair for the aortic arch diseases does not need cardio-pulmonary bypass. Ascending aorta banding technique strengthens the proximal anchoring area of the stent to avoid risks such as retrograde type A dissection, endoleak and migration. The operation owns small trauma, rapid recovery, low mortality and a low rate of reintervention, which may be considered as a safe and effective choice in the treatment of the elderly, high-risk patients with complex complications.
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.
ObjectiveReporting a case of hybrid procedure of extensive thoracoabdominal aortic aneurysm (TAAA) with type B dissection due to Marfan syndrome (MFS) using a prosthetic graft as the distal landing zone for stent-graft.MethodsRetrospectively summarize in-hospital profiles of a patient for who was diagnosed as MFS complicated with TAAA and type B dissection and admmited to Vascular Surgery Department of West China Hospital in May 2018. A GORE-TEX 18 mm×9 mm Y-shaped graft was sewn side-to-end to the bifurcation of left common iliac artery as the inflow site, and a self-made penta-limb graft was sewn side-to-end to the bifurcation of the 18 mm graft. The visceral and bilateral iliac arteries were reconstructed subsequently. Then, the release of the stent-graft was designed from distal to proximal. The distal part of the stent-graft was anchored into the main body of the 18 mm Y-shaped graft.ResultsThe patient underwent the operation successfully with a duaration of 6 h, blood loss of about 800 mL. No serious postoperative complications occurred. Computed tomography angiography at 2-year follow-up showed that the bypass grafts were patent without endoleak, stent migration, stent infolding or infections of the vessel graft and endograft.ConclusionThis modified management of the landing zone could be a proper choice for this kind of rare case as extensive aneurysm or dissection involved in patients with MFS.
ObjectiveTo explore the short- and mid-term efficacy of Castor single branch aortic stent combined with subclavian artery bypass grafting for the aortic arch lesions. MethodsA retrospective analysis of the clinical data of patients with proximal anchor zone insufficiency aortic arch lesions treated with Castor stent combined with subclavian artery bypass grafting at the Department of Cardiac Surgery, Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from August 2020 to November 2023 was performed. ResultsA total of 22 patients were included, including 19 males and 3 females, with an average age of (56±16) years. There were 18 patients of aortic dissection and 4 patients of aortic arch tumors. The success rate of surgical technique was 100.0%, and the average postoperative hospital stay for patients was (10±4) days. The median follow-up time was 20 months. During the follow-up period, there were no major complications such as endoleak, paraplegia, cerebral infarction, and renal insufficiency, and all patients had no readmissions. ConclusionFor proximal anchor zone insufficiency aortic arch lesions, the treatment method of using a Castor stent branch placed in the left common carotid artery can effectively extend the anchor zone, avoid the huge trauma of open chest surgery, and achieve a good short- and mid-term efficacy.
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.
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.
