Progress in surgical treatment of Kommerell's diverticulum

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.

OneStage Hybrid Operation for Treating Descending Aortic Diseases Involving Distal Aortic Arch

Abstract: Objective To summarize the clinical experiences of onestage hybrid operation for treating typeB aortic dissection and aortic aneurysm involving distal aortic arch, explore the indication for this special technique and analyze shortterm followup results. Methods From October 2008 to May 2010, 16 consecutive patients received onestage hybrid operation in Fu Wai Hospital for aortic dissection or aortic aneurysm involving distal aortic arch. There were 12 males and 4 females. Their age ranged from 38.0 to 67.0 years (54.0±9.2 years). There were 14 patients of typeB aortic dissection, 1 patient of thoracic aortic aneurysm involving the aortic arch, and 1 patient of penetrating aortic ulcer. Among them, 10 were acute ones and 6 were chronic ones. Brachiocephalic artery bypass using neck incision with retrograde endovascular stent graft implantation was used. Four patients received bypass from the left common carotid artery to the left subclavian artery; 11 patients underwent bypass from the right common carotid artery to the left common carotid artery; and 1 patient had both of the bypasses. Intensive care unit(ICU) stay, hospital stay， and incidence of complications were closely monitored after operation. Computed tomography(CT) and general condition of the bypass grafts and its blood flow were followed up at three months and one year after operation.  Results No death or severe complications occurred perioperatively. All onestage surgeries were technically successful with stent grafts implanted. Angiography during the operation showed 100% patency of all the bypass grafts and no obvious translocation or endoleakage of the stent grafts. One patient had mild paraplegia and recovered soon after treatment. Ventilation time of these patients was 2.010.0 hours (5.3±2.7 hours). The ICU stay was 0.0-2.0 days (1.1±0.4 days) and hospital stay was 4.0-7.0 days (5.3±0.8 days). The expenditure of blood products was 0.0-1 016.5 RMB (134.5±281.8 RMB). All patients were followed up with a followup period of 3.0 to 26.0 months (130±5.1 months). All patients recovered to normal social life. Enhanced CT scanning at three months and one year after operation showed no endoleakage or translocation of the stent grafts and 100% patency of the bypass grafts. There was no obvious change of the distal part of the dissection except some thrombosis formation in nine patients. Conclusion Onestage hybrid operation is safe and effective in shortening the duration of the operation and hospital stay, reducing the surgical trauma and sufferings of the patients, and lowering the risk of staged operations with satisfactory shortterm results. This special technique may expand the indications of simple endovascular repair. The mid and longterm results still need to be followed up.

Treatment choices of chronic thoracoabdominal aortic dissection aneurysm

The treatment of chronic thoracoabdominal aortic dissection aneurysm remains a major challenge in aortic surgery. Open surgery is the mainstream treatment at present. New devices for endovascular treatment of chronic thoracoabdominal aortic dissection are gradually applied in clinical practice. The hybrid procedure is a combination of open and endovascular procedures. The appropriate treatment should be selected according to the patient's age, anatomy, genetic aortic disease, and comorbidities.

Robot-assisted minimally invasive coronary artery bypass in treating multi-vessel coronary artery disease: A retrospective study in a single center

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.
