Objective Ascending aorta stent-grafting (AASG) is a new option that has shown initial promising results. In selected cases, when neither conventional surgery nor transfemoral retrograde approach are feasible, antegrade transapical (TA) access can be performed. The aim of this single-center retrospective study was to evaluate outcomes of patients undergoing AASG through a TA approach. Methods We analyzed all patients undergoing AASG through a TA approach at our institution. Three different devices were used, including Relay Stent-Graft System (Terumo Aortic, UK), Gore Conformable Thoracic Aortic Graft (W. L. Gore & Associates, Inc., USA), and Valiant Thoracic Stent Graft (Medtronic, Ireland). All patients underwent clinical and computed tomographic angiogram (CTA) evaluation before hospital discharge. Results From May 2010 to December 2019, 3 consecutive patients underwent AASG at our institution. Mean age was 69 years. Three different types of endografts were used in 1 patient each. All patients stayed in the intensive care unit for 24 hr and mean hospital stay was 12 days. We did not observe any major adverse event. One patient died of pneumonia 2 months after the procedure and the other 2 patients are alive and in good clinical conditions at a mean follow-up of 56 months. Predischarge CTA showed good anatomic results with no endoleaks in all cases. Conclusions This initial experience shows that AASG is feasible and provides encouraging clinical and anatomic results in selected high-risk patients.

Abstract. We conducted a systematic review regarding the efficacy and outcome of endovascular treatment of infected iliofemoral arterial pseudoaneurysms with covered stents. 35 cases were identified, including 5 own. 22 pseudoaneurysms were located in the femoral area and 13 in the iliac vessels. The most commonly reported complaints were pulsatile groin mass (40 %), sepsis (37.1 %), active bleeding (31.4 %), and groin infection with purulent discharge (17.1 %). S. aureus (65.7 %) and Streptococcus species (22.9 %) were the most common microbes isolated. Factors for the development of infected pseudoaneurysms were intravenous drug use (20 %), infection of anastomosis in bypass surgery (22.9 %), cancer (14.3 %), history of multiple hip operations (14.3 %), renal transplantation (2.9 %), and obesity (5.7 %). The most commonly used covered stents were Viabahn (22.9 %),Jostent (17.1 %), Fluency (14.3 %), and Wallgraft (14.3 %). In 15 cases, surgical debridement and/or drainage was also performed.The mean follow-up was 15.8 months. There were only 2 cases of stent graft thrombosis (5.7 %). 2 patients required an open vascular bypass procedure at a later stage. One death was attributed to procedure-related complications (2.9 %). The infection rate of the deployed stent graft in follow-up was 3.4 %. Endovascular exclusion of an infected pseudoaneurysm with primary stent grafting and drainage may be an option in high-risk patients.

Objectives To investigate the effectiveness of modified stent-grafts (SGs) for the management of ascending aortic pathologies. Materials and Methods From January 2015 to December 2019, 31 individuals were treated by ascending aortic endovascular repair with a back-table modified SG for acute (n=4) or chronic (n=1) type A aortic dissections, penetrating aortic ulcers (n=18), pseudoaneurysms (n=2), anastomotic fistula (n=1), and endoleaks after thoracic endovascular aortic repair (TEVAR) (n=5). The commercially available thoracic aortic SGs were modified with a fenestration or truncation technique on the back-table according to aortography during the operation. Results The 30-day mortality and aorta-related mortality rates were 12.9% and 6.5%, respectively. There were 2 strokes, 3 respiratory insufficiencies, and 6 endoleaks during hospitalization. During a mean follow-up of 28.8±16.6 months, the overall survival rates at 1 year and 3 years were both 80.6%. Free from adverse event rates at 1 year and 3 years were 88.9% and 84.7%, respectively. There were 2 deaths during follow-up: One patient died of cachexia 1 month after discharge, and the other patient died of acute myocardial infarction 3 months after discharge. One patient with a pseudoaneurysm underwent open ascending aorta replacement 3 months after discharge for a type Ia endoleak. Another patient suffered from cerebellar infarction 17 months after discharge. Conclusion The modified SG for endovascular repair of the ascending aorta is a practicable alternative and presents acceptable outcomes in high-risk patients.

Graft Implantation

Purpose: To outline the complications encountered after endoluminal treatment in patients with type B aortic dissection. Methods: Between 1999 and 2001, 14 patients (12 men; mean age 60.3 years, range 39–79) with isolated type B aortic dissection (13 chronic, 1 acute) underwent aortic stent-grafting. Three patients with chronic dissection presented an acute clinical picture and were managed emergently. The left subclavian artery was intentionally covered by the prosthesis in 9 patients. Follow-up studies were performed at 6-month intervals. Results: Stent-graft implantation was technically successful in all patients, but incomplete sealing (endoleak) of the entry site required additional proximal stent-graft implantation in 4. The left subclavian artery remained patent in 5 patients. Secondary conversion was required in 3 patients: 2 for acute type A dissection resulting from injury to the aortic arch by Talent endografts and a sustained hemorrhage (left hemothorax). In another patient, a secondary intramural hematoma subsided spontaneously. Anterior spinal artery syndrome in 1 patient persisted at 1 month. No bypass was necessary for the 9 patients with the covered left subclavian arteries. Mean follow-up was 14 months (range 1–23). Conclusions: Stent-grafting is feasible in patients with type B aortic dissection, although it is associated with a considerable rate of complications. Frank reporting of these sequelae for a variety of stent-grafts is of paramount importance to clarifying the limitations of the method.

Abstract An 84-year-old patient was referred for severe symptomatic aortic valve stenosis and focal chronic dissection of the ascending aorta. After multidisciplinary discussion, the patient was scheduled for combined transapical transcatheter aortic valve replacement and ascending aorta stent-grafting. The procedure was performed with a balloon aortic valvuloplasty followed by a custom-made stent graft implantation into the ascending aorta and then by balloon-expandable transapical transcatheter aortic valve replacement. The patient had an uneventful hospital stay. In conclusion, in selected high-risk patients, transapical combined ascending aorta stent-grafting and transcatheter aortic valve replacement are feasible and safe.

Popliteal Aneurysm

Purpose: To report the successful endovascular exclusion of a popliteal aneurysm using a saphenous vein stent-graft. Methods and Results: A 1.9-cm popliteal aneurysm in a 75-year-old man was excluded by an endovascular stent-graft constructed from a segment of a greater saphenous vein to which a Palmaz stent was attached at its proximal end. The operation was performed through an open posterior approach to the distal popliteal artery. The stent-graft was introduced in retrograde fashion and passed up to the superficial femoral artery, where the proximal stent was deployed. Distally, a conventional anastomosis was performed with standard suture technique. Follow-up at 2 months shows continued exclusion of the aneurysm and patency of the bypass. Conclusions: Saphenous stent-grafting is a promising technique in the less invasive treatment of popliteal aneurysms. Further experience and longer follow-up are required before this technique can replace open surgery in clinical practice.

Purpose: To evaluate the efficacy of stent-graft placement for the treatment of penetrating thoracic aortic ulcers. Methods: Ten patients (7 men; mean age 73.8 years, range 69–79) were treated for penetrating thoracic aortic ulcers using Talent or Excluder stent-grafts. Preoperative examinations included computed tomographic angiography (CTA), transesophageal echography, and digital subtraction angiography (DSA). Follow-up included predischarge multimodal imaging and periodic CTA scans after discharge. Endoleaks, aortic diameter changes, and clinical complications were tracked. Results: Technical success was achieved in 100%, but 1 major neurological complication led to death 3 months after the procedure. Radiological follow-up detected 4 early endoleaks (3 type I and a type II), all of which spontaneously regressed, and 1 secondary type II endoleak. The mean aortic diameter decreased by 22% over a mean 9-month follow-up. Conclusions: Aortic ulcers are potentially lethal lesions. Considering its low morbidity and mortality, endovascular repair could widen the treatment options for these lesions.

Aneurysm Repair

This study evaluated the value of computed tomographic angiography (CTA) early after an endovascular aneurysm repair (EVAR) in relation to CTA 3 months after EVAR. We retrospectively reviewed all elective EVAR patients with available postprocedural and 3-month follow-up CTAs who were treated between 1996 and 2006. CTAs were analyzed for EVAR-related complications in terms of endoleaks, migration, and stent graft thrombosis. Secondary procedures and other complications within a 4-month time interval after EVAR were noted and analyzed for any association with the postprocedural CTA. During the study period, 291 patients (275 men), with a mean age of 71 years, underwent elective EVAR. All had postprocedural and 3-month follow-up CTAs, which detected 93 (32%) endoleaks (8 type I, 84 type II, 1 type III) and 1 stent graft thrombosis. These findings resulted in four secondary interventions (one interposition cuff, two extension cuffs, one conversion). All reinterventions were successfully done in an elective setting. During the first 3 postoperative months, five other reinterventions were required for acute ischemia in four patients (three Fogarty procedures, one femorofemoral crossover bypass) or groin infection in one patient. Eight patients died, but none of the deaths were related to abdominal aortic aneurysm or EVAR (four cardiac, two pulmonary, one gastric bleeding, one carcinoma). At 3 months, 43 endoleaks (3 type I, 40 type II), 3 stent graft thromboses, and 1 stent graft migration were seen. In two patients (0.7%), a new endoleak was diagnosed compared with the postprocedural CTAs. In 287 (99%) of 291 patients, the postprocedural CTA did not influence our treatment policy in the first 3 months after EVAR. More than half of the early endoleaks were self-limiting, and new endoleaks were seen in only two patients (< 1%) at the 3-month follow-up CTA. After an uneventful EVAR procedure, it is safe to leave out the early postprocedural CTA.

Purpose: To evaluate the midterm outcomes of thoracic aortic stent-grafting and the performance of computed tomographic angiography (CTA), radiography, and magnetic resonance angiography (MRA) in endograft surveillance. Methods: Forty-seven patients with traumatic thoracic aortic ruptures (n=16), aneurysms (n=14), false aneurysms (n=3), penetrating ulcers (n=3), and dissections (n=11) treated with stent-grafts were monitored in follow-up using chest radiography and CTA in all patients and MRA in 23 patients. Two perpendicular maximal aortic diameters, the sum of these diameters, and the elliptical cross-sectional area were determined and compared to baseline for the entire group and in subgroup analyses according to lesion type. CTA, MRA, and radiography were compared for their ability to detect endoleak, monitor stent-graft configuration, and measure aortic diameters. Results: The mortality rate was 8.5%. Severe complications were observed in 14.8% (6% neurological complications); 12 (25.5%) patients had primary endoleaks. Over a mean 11-month follow-up (range 0.25–46 months), the aortic diameters decreased for all patients without endoleak (p<0.001). In the diameter/area subgroup analyses, only the traumatic rupture cohort demonstrated significant decreases in all 4 measurements. CTA and MRA measurements correlated well, but chest radiography was superior to both for visualizing stent-graft shape. In terms of endoleak detection, MRA missed only 1 (12.5%) endoleak (type II) seen on CTA; there were no false positive results with MRA. Conclusions: Morbidity and mortality observed after thoracic stent-grafting are acceptable. Radiography is better for monitoring stent-graft conformation, while CTA provides the best overall morphological information. The performance of MRA in endoleak detection is encouraging.

Purpose We performed antegrade thoracic endovascular aneurysm repair via the ascending aorta in selected high-risk patients scheduled for open surgery, in whom an iliofemoral or abdominal aortic approach was not feasible. We present our initial experience with this approach. Methods Of 16 consecutive patients who underwent antegrade endovascular aneurysm repair via the ascending aorta at our institution, 3 had an emergency intervention for rupture and 3 had an urgent intervention for impending rupture or complicated aortic dissection. The procedure was scheduled in 10 patients. The median patient age was 77 years. In 13 patients, one or more concomitant procedures were performed. In 6 patients, vascular access for endovascular aneurysm repair was obtained via a branch of the replacement graft. In 10 patients, direct cannulation of the ascending aorta was carried out using 2 pursestring sutures. Results The initial success rate was 100%. Early mortality occurred in 2 (12.5%) patients because of multiple organ failure in one and heart failure in the other. No patient required a second intervention during follow-up. The mean duration of follow-up was 19 months. Conclusion The antegrade approach is a useful alternative in patients with no access suitable for endovascular aneurysm repair and who are not appropriate candidates for open conventional thoracic aortic surgery. This approach is applicable to selected patients.
