Surgical treatment of thoracoabdominal aortic aneurysms

INTRODUCTION. Aneurysms simultaneously involving the thoracic and abdominal aortas or those aneurysms that include the visceral aortic segment are defined as thoracoabdominal aortic aneurysms (ThAAA). Their treatment is one of the most difficult surgical problems today. OBJECTIVE. The purpose of this paper is to present the early results of the surgical treatment of type IV ThAAA, according to the Crawford classification, as well as to analyse the main problems encountered during this procedure. METHOD. Between January 2001 and the end of 2004, 79 patients with type IV ThAAA, according to the Crawford classification were treated at the Clinic for Vascular Surgery of the Institute for Cardiovascular Diseases of the Serbian Clinical Centre. Lumbotomy combined with extrapleural resection of the XI or X rib was used as the operative approach in 70 cases, while thoracophrenolumbotomy was performed in 9 cases. The aneurysm was repaired using the bifurcated Dacron graft in 38 cases and with the tube Dacron graft in 41 cases. In 47 cases, visceral arteries were reattached using the Carrel patch technique, while in 31 cases, separate revascularisation of the left kidney was required. RESULTS. 60 (76%) of our patients survived the first 30 postoperative days, while 19 (24%) died during this period. The causes of mortality included: haemorrhaging, in 4 patients; pulmonary embolism, in 1 patient; myocardial infarction, in 4 patients; ARDS, in 2 patients; and finally, multi-organ system failure, in 8 patients. Statistical analysis showed that advanced age (over 70 years), the need for more extensive reconstructive surgery along with the implantation of the bifurcated graft, as well as the presence of ruptured aneurysms, significantly increased the mortality of the patients. CONCLUSION. The surgical management of ThAAA requires a multidisciplinary approach. We introduced this procedure in our hospital 4 years ago. The further development of this surgery will be of great medical, social, and economic importance to our country.

Procedural Success

Background: Thoracoabdominal aortic aneurysms (TAAA) present a significant clinical challenge, as they are complex and require invasive surgery. In an attempt to prevent considerably high mortality and morbidity in open repair, hybrid endovascular repair has been developed by many authors. In this study, we evaluated the early-term results obtained from this procedure.Methods: From November 2010 to February 2013, we performed thoracoabdominal hybrid aortic repair in 18 patients. The mean age was 68 years (12 men, 6 women). All of the patients had significant comorbidities. Follow-up computed tomography (CT) scans were performed at 1 week, 3 months, 6 months, and annually thereafter.Results: All patients were operated on in a staged procedure and stent graft deployment was achieved. Procedural success was achieved in all cases. All patients were discharged with complete recovery. No endoleaks weres detected in further CT examination.Conclusion: Our results suggests that hybrid debranching and endovascular repair of extensive thoracoabdominal aneurysms represents a suitable therapeutic option to reduce the morbidity and mortality of TAAA repair, particularly in those typically considered at high risk for standard repair.

Objectives Thoracic endovascular aortic repair (TEVAR) is the standard of care for descending thoracic aortic aneurysms (DTAA), and newer generation stent grafts have significant design improvements compared to earlier generation devices. Methods We report the first commercial use of the Medtronic Valiant Navion stent graft for treatment of an 85-year-old woman with a 5.8 cm DTAA and a highly tortuous thoracic aorta. Results A percutaneous TEVAR was performed using a two-piece combination of the Valiant Navion FreeFlo and CoveredSeal stent graft configurations for zones 2–5 coverage. The devices were successfully delievered through highly tortuous anatomy and deployed, excluding the entire length of the aneurysm with precise landing, excellent apposition and no evidence of endoleak. The patient tolerated the procedure well and has had no stent graft-related complications through one-year follow-up. Conclusions Design enhancements such as a lower profile delivery system, better conformability, and a shorter tapered tip are some of the improvements to this third-generation TEVAR device. Coupled with the multiple configuration options available, this gives physicians a better tool to treat thoracic aortic pathologies in patients with challenging anatomy. The early results are encouraging, and evaluation of long-term outcomes will continue.

Purpose: Fenestrated endovascular aneurysm repair (FEVAR) is a well-established endovascular treatment option for pararenal abdominal aortic aneurysms in which balloon-expandable covered stents (BECS) are used to bridge the fenestration to the target vessels. This study presents midterm clinical outcomes and patency rates of the Advanta V12 BECS used as a bridging stent. Methods: All patients treated with FEVAR with at least 1 Advanta V12 BECS were included from 2 large-volume vascular centers between January 2012 and December 2015. Primary endpoints were freedom from all-cause reintervention, and freedom from BECS-associated complications and reintervention. BECS-associated complications included significant stenosis, occlusion, type 3 endoleak, or stent fracture. Secondary endpoints included all-cause mortality in-hospital and during follow-up. Results: This retrospective study included 194 FEVAR patients with a mean age of 72.2±8.0 years. A total of 457 visceral arteries were stented with an Advanta V12 BECS. Median (interquartile range) follow-up time was 24.6 (1.6, 49.9) months. The FEVAR procedure was technically successful in 93% of the patients. Five patients (3%) died in-hospital. Patient survival was 77% (95% CI 69% to 84%) at 3 years. Freedom from all-cause reintervention was 70% (95% CI 61% to 78%) at 3 years, and 33% of all-cause reinterventions were BECS associated. Complications were seen in 24 of 457 Advanta V12 BECSs: type 3 endoleak in 8 BECSs, significant stenosis in 4 BECSs, occlusion in 6 BECSs, and stent fractures in 3 BECSs. A combination of complications occurred in 3 BECSs: type 3 endoleak and stenosis, stent fracture and stenosis, and stent fracture and occlusion. The freedom from BECS-associated complications for Advanta V12 BECSs was 98% (95% CI 96% to 99%) at 1 year and 92% (95% CI 88% to 95%) at 3 years. The freedom from BECS-associated reinterventions was 98% (95% CI 95% to 100%) at 1 year and 94% (95% CI 91% to 97%) at 3 years. Conclusion: The Advanta V12 BECS used as bridging stent in FEVAR showed low complication and reintervention rates at 3 years. A substantial number of FEVAR patients required a reintervention, but most were not BECS related.

Continuous Bleeding

Ascending aortic aneurysms involving the proximal aortic arch, arising anywhere from the aortic valve to the innominate artery, represent various problems in which open surgery is generally required. Surgical options include excision of the aortic pathology or wrapping the aneurysm shell with an aortic Dacron graft. Intervention using the latter method can lead to extravasation of blood along the suture lines resulting in continuous bleeding within the periprosthetic space. The Cabrol technique was developed as a method for decompression of postoperative leaks by the formation of a conduit system from the periprosthetic space to the right atrium. The coronary ostia are anastomosed to a second graft in an end-to-end fashion, which is then anastomosed to the ascending aortic conduit side to side. The native aorta is then sewn around the prosthesis, hereby creating a shunt to drain anastomotic leakage. This shunt reduces postsurgical risk of pseudoaneurysm formation and normally closes a few days following surgery. We discuss the case of a patient who underwent Cabrol’s variation and six months later was demonstrated to have a patent shunt.
