  • 胸主动脉瘤及主动脉夹层外科治疗进展

    胸主动脉瘤及主动脉夹层病情凶险,死亡率和病残率均很高.近几年在保留和不保留主动脉瓣的主动脉根重建术治疗升主动脉瘤,弓部主动脉瘤切除与脑保护,胸主动脉瘤或胸腹主动脉瘤切除与脊髓保护,以及主动脉腔内支架移植术等方面取得了较大的进展.手术死亡率已从31.4%下降至3.3%~4.8%.胸主动脉瘤,特别是主动脉夹层系一全身性主动脉病变,近年来手术疗效有所改善,但远期复发率和再手术率仍较高.主动脉内支架移植与外科手术结合应用,对复杂的伴有降主动脉病变的A型主动脉夹层治疗,可能是一种安全而有效的方法.

  • COMPARISON OF EARLY EFFECTIVENESS BETWEEN TOTAL PERCUTANEOUS ENDOVASCULAR ANEURYSM REPAIR AND SURGICAL FEMORAL CUTDOWN ENDOVASCULAR ANEURYSM REPAIR FOR ASYMPTOMATIC ABDOMINAL AORTIC ANEURYSM

    Objective To investigate the early effectiveness of total percutaneous endovascular aneurysm repair (TPEVAR) in treating asymptomatic abdominal aortic aneurysm (AAAA) by comparing with surgical femoral cutdown endovascular aneurysm repair (SFCEVAR). Methods Between January 2010 and May 2011, 41 cases of AAAA were treated with TPEVAR in 26 cases (TPEVAR group) and with SFCEVAR in 15 cases (SFCEVAR group). The maximum tumor diameter ranged from 3.5 to 9.2 cm (mean, 5.7 cm) in TPEVAR group, and ranged from 3.5 to 10.0 cm (mean, 6.9 cm) in SFCEVAR group. There was no significant difference in gender or age between 2 groups (P gt; 0.05). Results All patients underwent EVAR successfully. The patients were followed up 6-23 months (mean, 13.5 months). No significant difference was found in the outer diameters of the delivery system for main body and iliac leg, operation time, contrast media dosage, hospitalization days, or postoperative hospitalization days between 2 groups (P gt; 0.05). The patients of SFCEVAR group had more bleeding volume and longer ICU stay than patients of TPEVAR group (P lt; 0.05). The incidence of minor complication was 7.7% (2/26) in TPEVAR group and 33.3% (5/15) in SFCEVAR group, showing no significant difference between 2 group (χ2=4.42, P=0.08); the incidence of major complication in SFCEVAR group (20.0%, 3/15) was significantly higher than that in TPEVAR group (0) (χ2=5.61, P=0.02). Conclusion TPEVAR shows safer and more effective than SFCEVAR in treating AAAA.

  • Research progress on perioperative management of thoraco-abdominal aortic aneurysm surgery

    The surgical treatment of thoraco-abdominal aortic aneurysm (TAAA) requires a unique multidisciplinary approach. A thorough preoperative examination and evaluation are essential to determine the optimal timing for surgery and to optimize organ function as needed. During the perioperative period, excellent surgical skills and an appropriate strategy for extracorporeal circulation will be employed based on the extent of the aneurysm. Additionally, necessary measures will be taken to monitor and protect the functions of vital organs. Close monitoring and management in the postoperative stage, along with early detection of complications and effective treatment, are crucial for improving the prognosis of TAAA surgery. This article reviews the current research progress in the perioperative management of TAAA surgery.

  • COMPARISON OF ENDOVASCULAR REPAIR AND OPEN REPAIR FOR RUPTURED ABDOMINAL AORTIC ANEURYSM

    Objective To compare the effectiveness between conventional open repair (OR) and endovascular repair (EVRAR) for ruptured abdominal aortic aneurysm. Methods Between March 2000 and July 2011, 48 cases of ruptured abdominal aortic aneurysm were treated by conventional OR in 40 cases (OR group) or by EVRAR in 8 cases (EVRAR group). There was no significant difference in age, sex, the neck length (less than 2 cm), the neck angulation of aneurysm (more than60°), il iac severe tortuosity, preoperative systol ic pressure, and preoperative comorbidity between 2 groups (P gt; 0.05). The blood transfusion volume, operation time, intensive care unit (ICU) stay, postoperative complications, reinterventions, and mortality were analyzed. Results There was no significant difference in 24-hour and 30-day mortality rates and non graft-related complications between 2 groups (P gt; 0.05). EVRAR group was significantly better than OR group in blood transfusion volume, operation time, and ICU stay (P lt; 0.05), but OR group was significantly better than EVRAR group in reinterventions and graftrelated complications (P lt; 0.05). Conclusion EVRAR has obvious advantages in blood transfusion volume, operation time, and ICU stay, so it is feasible for ruptured abdominal aortic aneurysm in patients with precise anatomical suitability.

  • Advances in surgical indications and morphological rupture-risk assessment of abdominal aortic aneurysms

    ObjectiveThis paper aimed to summarize the new progress in surgical indications regarding as maximum diameter from evidence-based medical evidence and morphological rupture-risk assessment of abdominal aortic aneurysms (AAA) and its clinical application value.MethodThe rupture-risk and its mechanism of AAA in specific population and morphological characteristics were reviewed.ResultsAsymptomatic patients in specific subgroups may also benefit from AAA repair by lowering the intervention threshold. Besides the maximum diameter of aneurysm, other morphological factors, such as the true geometric shape, the wall thickness, and mural thrombus also had important predictive value for AAA rupture risk.ConclusionRupture-risk assessment based on the actual individual situation of AAA patients can further facilitate the clinical diagnosis and treatment.

  • Hybrid Procedures in Treatment for Aortic Arch Lesions: Short- and Long-Term Results

    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 longterm survival of these patients. ResultsHybrid procedures included 12 totalarch 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 followup 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.
