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.
ObjectiveTo explore the progresses of diagnosis and treatment for endoleaks after endovascular repair of abdominal aortic aneurysm (EVAR). MethodsThe literatures on studying the classification, diagnosis and management, risk factor, and treatment for the endoleaks after EVAR were reviewed and analyzed. ResultsEndoleak was a common and particular complication after EVAR and its represented persistence meant failure of the EVAR treatment. Accurate detection and classification were essential for the proper management and the treatment method for the endoleak was determined by the different source. Type Ⅰ and type Ⅲ endoleak required urgent treatment， type Ⅱ and type Ⅴ were considered less urgently but may be observed continuously. A variety of techniques including extension endografts or cuff, balloon angioplasty, bare stents, and a combination of transvascular and direct sac puncture embolization techniques were allowed to treat the vast majority of these endoleaks. ConclusionsEndoleak after EVAR is still the main clinical problem to be solved. The characters of endoleak still are not fully revealed. The diagnosis and treatment remained equivocal, which requires further study.
Objective To compare the advantages and disadvantages between double Perclose ProGlide crossing suture and traditional suture for the closure of 20F or 22F access points so as to provide a basis for selecting appropriate approach to repair the puncture points in endovascular aortic repair. Methods Between June 2007 and May 2011, 103 patients (115 common femoral arteries) underwent endovascular aortic repair using sheaths of 20F or 22F (outer diameter); double Perclose ProGlide crossing suture was performed for closure of puncture sites in 57 cases (64 common femoral arteries) (double Perclose group) and traditional suture in 46 cases (51 common femoral arteries) (traditional group). There was no significant difference in age, gender, or disease duration between 2 groups (P gt; 0.05). Results The operation time, blood loss, and hospitalization days of double Perclose group were significantly better than those of traditional group (P lt; 0.05). Ecchymoma in inguinal region and lymphatic leakage occurred in 5 cases (5 common femoral arteries) and 2 cases (2 common femoral arteries) of double Perclose group respectively, in 2 cases (2 common femoral arteries) and 6 cases (8 common femoral arteries) of traditional group respectively; no significant difference was found in the rate of the early complication between double Perclose group and traditional group (7.8% vs. 15.7%, χ2=1.76, P=0.19). The technique success rate of double Perclose group was 96.9% (62/64), and was 100% (51/51) in traditional group, showing no significant difference (χ2=0.31, P=0.50). All patients were followed up, 2-19 months (mean, 15 months) in double Perclose group and 2-18 months (mean, 14 months) in traditional group. Pseudoaneurysm occurred in the puncture region at 3 months in 1 case (1 common femoral artery) of double Perclose group, and incision and suture therapy was performed; no arteriostenosis or pseudoaneurysm occurred in other cases; and the rate of mid-term complication was 1.6% (1/64) in double Perclose group and was 0 in traditional group, showing no significant difference (P=1.000). Conclusion Double Perclose ProGlide crossing suture has the same effectiveness to traditional surture in repairing the puncture point with 20F or 22F, but it is superior to traditional suture in reducing operation time, blood loss, and hospitalization days.
Aortic dissection is a disease with high mortality rates. Due to the urgency of time, the diagnosis, treatment processes, and strategies of acute aortic dissection follow specific guidelines. However, patients with chronic aortic dissection are often neglected. Choosing the best medication therapy and surgical interventions remains challenging, and there is still a lack of guideline recommendations. With the improvement of imaging diagnostic methods for aortic diseases, the progress of endovascular surgical techniques, and the development of new endovascular graft devices in recent years, clinical data of the treatment of chronic aortic dissection is also gradually increasing. This article summarized the current new technologies and clinical research results for the diagnosis and treatment of chronic aortic dissection, aiming to provide new suggestions for the diagnosis and treatment of chronic aortic dissection.
Objective To summarize the clinical experience of capture technology in the large diameter of abdominal aortic aneurysm in endovascular repair of abdominal aortic aneurysm(EVAR). Methods We retrospectively analyzed clinical data of 6 patients with abdominal aortic aneurysm (maximum diameter of 6.0 cm or bigger) in our hospital between July 2013 and May 2014.There were 3 males and 3 females at age of 76.2(73–81) years. Two patients of ruptured abdominal aortic aneurysm, in EVAR, established orbit using the capture technology successfully. Results The capture technology made the thread through the proximal tumor neck smoothly, successful repaired. One patient of rupture of abdominal aortic aneurysm was dead after 10 hours. One patient was lost to follow-up. Four patients were followed up for 3 to 11 months. The four patients had not occurred bracket displacement, internal leakage, thrombosis, or other serious complications. Conclusion For the patients with larger abdominal aortic aneurysm, capture technology may be used to the thread through the proximal tumor neck, to build a convey or track easily, to shorten the operation time, to improve the success rate of surgery.
ObjectiveTo explore the efficacy of using a single branch stent-graft to treat primary intramural hematoma located at the distal arch or descending aorta in Stanford A type aortic intramural hematoma. MethodsFrom July 2020 to November 2022, 10 patients with primary intramural hematoma of Stanford A type aortic intramural hematoma were treated with endovascular repair using a single branch stent-graft in the Department of Cardiovascular Surgery at The University of Hong Kong-Shenzhen Hospital. There were 9 males and 1 female, aged from 32 to 66 years, with a mean age of (47.0±10.4) years. All patients had intramural hematoma involving the ascending aorta and aortic arch, diagnosed as type A intramural hematoma, with the tear located in the descending aorta. Among them, 6 patients were complicated by ulceration of the descending aorta with intramural hematoma, and 4 patients had changes of the descending aortic dissection. All patients underwent endovascular stent repair, with 8 patients undergoing emergency surgery (≤14 days) and 2 patients undergoing subacute surgery (15 days to 3 months). Results There were no neurological complications, paraplegia, stent fracture or displacement, or limb or visceral ischemia during the perioperative period in all patients. One patient had continuous chest pain after surgery, and the stent had a new tear at the proximal end, requiring ascending aorta and partial arch replacement. As of the latest follow-up, all patients had obvious absorption or complete absorption of the intramural hematoma in the ascending aorta and aortic arch compared with before the operation. ConclusionSingle branch stent-graft treatment of retrograde ascending aortic intramural hematoma is safe and effective, with good short-term results.
ObjectiveTo discuss the risk factors of type Ⅱ endoleak after endovascular aneurysm repair(EVAR). MethodsThe clinical data of 197 cases of abdominal aortic aneurysm who underwent EVAR in our hospital from Jan. 2006 to Mar. 2011 were analyzed retrospectively, and risk factors of type Ⅱ endoleak were explored by logistic regression. ResultsOf the 197 cases, 18 cases suffered from type Ⅱ endoleak. Result of logistic regression showed that the risk of type Ⅱ endoleak increased per 1 of the increase of lumbar artery number(OR=1.822, P=0.010) and per 1 mm of the increase of lumbar artery diameter(OR=1.256, P=0.040). All of the cases were followed up for 1-36 months(median value of 16.8 months). Only 1 case was intervened by inferior mesenteric artery embolism for the growth rate larger than 5 mm during half a year, who was not found growth of diameter after the embolism. The type Ⅱ endoleaks of other 17 cases closed ultimately or keeping stable. ConclusionsType Ⅱ endoleak after EVAR is affected by the number and diameter of lumbar artery. Persistent type Ⅱ endoleak without enlargement of diameter of aneurysm sac needs to beclosely followed-up instead of re-intervention.
Transcatheter aortic valve replacement and endovascular abdominal aortic repair have now become the first-line treatment options for aortic stenosis and abdominal aortic disease, respectively. For patients with both diseases, combined procedures have been reported in a few domestic and foreign publications. However, all the procedures were performed under general anesthesia. Here, we reported a case of simultaneous minimalist transfemoral transcatheter aortic valve replacement and endovascular repair of the abdominal aorta for a 78-year-old male patient with aortic stenosis and abdominal aortic ulcer, and the surgical results were satisfactory.
ObjectiveTo determine the influence of proximal aneurysm neck anatomy on typeⅠA endoleak follo-wing endovascular aortic aneurysm repair (EVAR) for infrarenal abdominal aortic aneurysm. MethodsFrom September 2007 to February 2014, 111 consecutive patients with non-ruptured abdominal aortic aneurysms were treated with EVAR. The preoperative CTA of abdominal aortic was obtained by every patient, and the three-dimensional imaging was reconstructed and measured by software of Osorix. Then, the relation between the recurrence of typeⅠA endoleak and the concerned data measured by Osorix was analyzed by the statistical software. ResultsThe recurrence of typeⅠA endo-leak was related to the proximal neck angle of the abdominal aortic aneurysm, which weren't related to the proximal neck diameter and variation rates, the mural thrombas and calcification rate, and the maximum diameter of abdominal aortic aneurysm by multivariate analysis. ConclusionsThe complicated proximal aneurysm neck anatomy is a major cause for the typeⅠA endoleak, the proximal neck angle of the abdominal aortic aneurysm is the independent factor. The applica-tion of EVAR depends largely on the shape of the proximal aneurysm neck.
