Nowadays, the development of the medical instrument industry makes rapid changes in clinical practice. Hybridization of latest technology is playing an increasingly important role in the diagnosis and treatment of disease. Especially, the trend of the integration of three-channel hybrid technology in diagnosis and treatment of early lung cancer has become increasingly obvious. This paper will focus on the technical advance of the three-channel multi- mirror robot and its application in the diagnosis and treatment of early lung cancer.
Atrial fibrillation (AF) is the most common cardiac arrhythmia and is known to be associated with stroke, dementia, heart failure, and increased mortality. For patients with drug-refractory AF, ablation therapy using surgical or catheter-based techniques is recommended. In the evolution of surgical AF treatment, the Maze Ⅲ procedure marked a significant milestone as the first surgical approach to achieve a high success rate in restoring sinus rhythm. However, due to its technical complexity and demanding requirements, researchers have extensively modified the technique using innovative approaches, leading to the development of new surgical ablation methods, including the Maze Ⅳ procedure, minimally invasive Maze Ⅳ surgery, and hybrid ablation techniques. This review focuses on these surgical treatment strategies and discusses the latest research advancements in the field.
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.
Objective To evaluate the immediate and mid-term effectiveness of hybrid procedures (combined open surgery and endovascular therapy) for multilerel femoral and popliteal artery occlusive disease. Methods Between June 2009 and June 2012, 22 cases of severe femoral and popliteal artery occlusive disease were treated by hybrid surgery. There were 15 men and 7 women with an age range of 52-78 years (mean, 66.2 years) and with a disease duration of 6 months to 5 years (mean, 1.5 years). Of 22 patients, 13 had a history of smoking; 8 were classified as Fontaine III and 14 as Fontaine IV. The complications included diabetes (8 patients), hypertension (16 patients), hyperlipemia (10 patients), coronary heart disease (11 patients), and chronic kidney failure (1 patient). Patency analyses were performed using Kaplan-Meier life tables and log-rank test. Results All patients underwent successfully procedures. The time of operation was 70-160 minutes (mean, 137 minutes). Acute myocardial infarction, hematoma of incision, fracture of stent, and stent thrombosis occurred in 1 case, respectively. At 6 months after surgery, the ankle brachial index (ABI), the transcutaneous oxygen pressure (TcpO2), and the average intermittent claudication distance were significantly increased when compared with preoperative ones [0.79 ± 0.33 vs. 0.32 ± 0.18, (42.7 ± 15.7) kPa vs. (17.6 ± 11.6) kPa, and (420 ± 80) m vs. (160 ± 54) m, P lt; 0.05]. The patients were followed up 6-24 months (mean, 14.5 months). The primary patency rate, primary assisted patency rate, and second patency rate were 77.3% (17/22), 90.9% (20/22), and 95.5% (21/22) respectively, showing no significant difference among them (P gt; 0.05). No significant difference was found in various-stage patency rates between patients at Fontaine III and IV (P gt; 0.05). Conclusion Hybrid procedures provide an effective treatment of multilevel femoral artery and popliteal artery disease while there is good outflow.
ObjectiveTo evaluate the early and mid-term results of robot-assisted coronary artery bypass grafting (RACAB) in the treatment of multi-vessel coronary artery disease (MV-CAD). Methods Patients with MV-CAD who underwent RACAB from April 2018 to December 2021 in our hospital were included. Patients who underwent hybrid coronary revascularization (HCR) which combined RACAB with percutaneous coronary intervention were allocated to a HCR-RACAB group, and patients who underwent multi-vessel RACAB were allocated to a MV-RACAB group. Perioperative and follow-up data were collected and compared between the two groups. Results A total of 102 patients were included, including 81 males and 21 females with a mean age of 61.7±10.8 years. Two (2.0%) patients were transferred to conventional CABG due to sudden ventricular fibrillation and pleura adhesion. In the remaining 100 patients who underwent RACAB, 100 left internal mammary arteries (LIMA) and 46 right internal mammary arteries (RIMA) were harvested with a 100.0% success rate. Besides, all patients undergoing RACAB achieved LIMA/RIMA-left anterior descending branch reconstruction, with an average number of 2.5±0.6 target vessels revascularized by stent or graft. One patient had perioperative myocardial infarction with an outcome of death. The incidence of major perioperative adverse events was 1.0%. There was no perioperative stroke or re-sternotomy for hemostasis. The mean follow-up time was 28.2 months, with a follow-up rate of 99.0% and an overall major adverse cardiac and cerebrovascular event (MACCE) rate of 7.0%, including 3 all-cause deaths (3.0%), 2 strokes (2.0%) and 3 re-revascularizations (3.0%). The HCR-RACAB group had fewer red blood cell transfusion (P=0.030) and intraoperative blood loss (P=0.037) compared with the MV-RACAB group, and there was no statistical difference in the incidence of major perioperative adverse events or MACCE between the two groups during the follow-up period (P>0.05). ConclusionRACAB can be safely applied in the treatment of MV-CAD with good early and mid-term outcomes. High-quality harvesting of LIMA/RIMA and aortic no-touch technique are crucial to achieve these results.
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.
ObjectiveTo compare the clinical efficacy of typeⅡhybrid surgery versus Sun’s surgery in treating acute Stanford A aortic dissection. MethodsA retrospective analysis was conducted on the clinical data of patients with acute Stanford A aortic dissection who were treated at the Central Hospital of Wuhan affiliated to Tongji Medical College, Huazhong University of Science and Technology from 2016 to 2022. According to the surgical method, patients were divided into a typeⅡhybrid group and a Sun’s surgery group, and the clinical efficacy of the two groups was compared. ResultsA total of 52 patients were included, with 22 in the typeⅡhybrid surgery group and 30 in the Sun’s surgery group. The typeⅡhybrid group consisted of 18 males and 4 females, with an average age of (58.18±6.00) years, while the Sun’s surgery group consisted of 22 males and 8 females, with an average age of (53.03±11.89) years. All surgeries were successfully completed. There were 4 (13.3%) perioperative deaths in the Sun’s surgery group, including 2 patients of multiple organ failure, 1 patient of paraplegia, and 1 patient of uncontrollable postoperative bleeding. There was 1 (4.5%) perioperative death in the typeⅡhybrid surgery group, who was suspected of acute coronary syndrome and took a loading dose of dual antiplatelet drugs preoperatively. The patient underwent secondary thoracotomy for hemostasis, was re-cannulated during the operation, and finally died of circulatory failure after implantation of intra-aortic balloon pumping. There was no statistical difference in perioperative mortality between the two groups (P=0.381). Compared with the Sun’s surgery group, the typeⅡhybrid surgery group had shorter cardiopulmonary bypass time [153.00 (135.00, 185.25) min vs. 182.50 (166.50, 196.75) min, P=0.013], aortic cross-clamping time [77.00 (70.50, 92.00) min vs. 102.50 (93.50, 109.75) min, P<0.001], postoperative ICU stay [4.00 (2.83, 6.00) days vs. 8.00 (6.38, 11.78) days, P<0.001], postoperative ventilator support time [72.00 (29.50, 93.25) h vs. 87.65 (39.13, 139.13) h, P=0.138], less intraoperative blood loss [(1586.82±209.41) mL vs. (1 806.00±292.62) mL, P=0.004], postoperative 24 h drainage volume [612.50 (507.50, 762.50) mL vs. 687.50 (518.75, 993.75) mL, P=0.409], and shorter postoperative hospital stay [18.00 (13.00, 20.25) days vs. 22.00 (17.00, 29.25) days, P=0.013]. There was no statistically significant difference in the incidence of other early postoperative complications such as secondary thoracotomy for hemostasis, tracheotomy, renal dysfunction requiring dialysis, stroke, and paraplegia between the two groups (P>0.05). ConclusionFor patients with acute Stanford A aortic dissection, typeⅡhybrid surgery is safe and effective; compared with traditional Sun’s surgery, typeⅡhybrid surgery has relatively less trauma, lower incidence of complications, satisfactory short-term results, and further research is needed on long-term prognosis.
