Objectives: To report outcomes of thoracic endovascular repair using customized single-branched fenestrated stent-grafts in treatment of aortic arch dissections. Materials and Methods: Between November 2009 and November 2011, 16 patients with aortic arch dissections underwent thoracic endovascular aortic repair utilizing customized unibody single-branched fenestrated stent-graft (UBFSG) in our institution. Results: All 16 patients were male with mean age of 54.50 ± 11.33. The technical success rate was 100%. 30-day mortality rate was 6.25% (n = 1). The median follow-up period was 98 months (range, 0-119). During follow-up, 4 nonaorta-related deaths were recorded. Two (2) cases of left subclavian artery occlusion were observed 12 and 14 months after the operation. Two (2) patients had another successful endovascular repair in time, including one case of type Ib endoleak occurred 100 months after the operation and one case of stent-graft induced new entry tear 38 months after the operation. No stroke and migration of stent-grafts were observed. Conclusions: The branched fenestrated stent-graft may be an effective alternative treatment for aortic arch dissections unfit for open surgery.

Objectives This study evaluated the feasibility and safety of total endovascular aortic arch repair with surgeon-modified fenestrated stent-graft on zone 0 landing for aortic arch pathologies. Methods Between June 2016 and October 2019, 37 consecutive patients underwent total endovascular arch repair with surgeon-modified fenestrated stent-grafts on zone 0 landing. Outcomes included technical success, perioperative and follow-up morbidity and mortality, and branch artery patency. Results During the study period, 37 patients were treated with total endovascular aortic arch repair with surgeon-modified fenestrated stent-graft. Twenty-one (56.8%) patients were diagnosed with aortic dissections, 15 (40.5%) patients with aneurysms, and 1 (2.7%) patient required reintervention due to endoleak and sac expansion from previous thoracic endovascular aortic repair for thoracoabdominal aneurysm. The proximal landing zone for all patients were in zone 0, and all branch arteries of aortic arch were reconstructed. Technical success was achieved in 34 cases (91.9%). Three (8.1%) patients had fenestrations misaligned with target arteries, and the chimney technique was applied as a complementary measure. Thirty-day mortality rate was 5.4% (n=2). Thirty-day stroke rate was 5.4% (n=2). Thirty-day reintervention rate was 2.7% (n=1). At a median follow-up of 20 months (range, 3–49 months), 5 (13.5%) patients died, including 2 aortic-related deaths, 1 nonaortic-related death, and 2 deaths of unknown reason. One (2.7%) patient had stroke. Four patients (10.8%) had reintervention during the follow-up, including 2 cases of left subclavian artery occlusion and 2 cases of type II endoleak. The estimated survival (±SE) at 2 years was 72.4%±9.7% (95% CI 53.4%–91.4%). The estimated freedom from reintervention (±SE) at 2 years was 87.4%±5.9% (95% CI 75.84%–98.96%). Conclusions Total endovascular aortic arch repair with surgeon-modified fenestrated stent-grafts on zone 0 landing is an alternate option for the treatment of aortic arch pathologies in experienced centers.

Objective The present study aims to analyze the outcomes of three cases of pre-fenestration and branch stent-graft endovascular repair of aortic disease with zone 2 aortic lesions. Methods From August 2017 to June 2018, three patients with zone 2 aortic lesions underwent thoracic endovascular repair with innominate artery, left common carotid artery, and left subclavian artery recannulation using pre-fenestration and branched stent-grafts to preserve the patency of the aortic arch branches. Results The technical success rate was 100%. One patient had a proximal type I endoleak with no need for additional treatment. The overall mortality was 0%. All branches were patent. The follow-up period lasted for 2–15 months, with one patient lost to follow-up. There were no conversions to open surgical repair, aortic rupture, paraplegia, or retrograde type A aortic dissection. Conclusion The use of a pre-fenestration and branch stent-graft for the thoracic endovascular repair of zone 2 aortic lesions is a feasible and effective method for aortic arch branch revascularization. The risk of this surgical procedure is high, requiring significant expertise. The procedure should be conducted only in experienced centers. Durability concerns should be assessed in future studies with long-term follow-up.

Purpose: To evaluate outcomes of homemade fenestrated stent-grafts for complete endovascular aortic repair of aortic arch dissections. Materials and Methods: From July 2014 through September 2018, 35 patients (mean age 66±11 years; 25 men) underwent homemade fenestrated stent-graft repair of acute (n=16) or chronic (n=10) complicated type B aortic dissections (n=16) and dissecting aortic arch aneurysms subsequent to surgical treatment of acute type A dissections (n=9). Nineteen (54%) procedures were emergent. Results: Zone 2 single-fenestrated stent-grafts were used in 25 cases; the remaining 10 were double-fenestrated stent-grafts deployed in zone 0. Median time for stent-graft modification was 18 minutes (range 16–20). Technical success was achieved in all cases. An immediate distal type I endoleak was treated intraoperatively. Among the double-fenestrated stent-graft cases, the left subclavian artery fenestration could not be cannulated in 2 patients and revascularization was required. Partial coverage of the left common carotid artery necessitated placement of a covered stent in 3 cases. One (3%) patient had a stroke without permanent sequelae. Two type II endoleaks required additional covered stent placement at 5 and 7 days postoperatively, respectively. The 30-day mortality was 6% (2 patients with ruptured aortic arch aneurysm). During a mean follow-up of 17.6±13 months, there was no aortic rupture or retrograde dissection. One late type I endoleak was treated with additional proximal fenestrated stent-graft placement. One type II endoleak is currently under observation. One additional patient died (unrelated to the aorta); overall mortality was 9%. All supra-aortic trunks were patent. Conclusion: The use of homemade fenestrated stent-grafts for endovascular repair of aortic arch dissections is feasible and effective for total endovascular aortic arch repair. Durability concerns will need to be assessed in additional studies with long-term follow-up.

Blunt Traumatic Aortic Injury

Abstract Background Endovascular stent grafting has emerged as an option to treat traumatic aorta injuries with reported significantly low mortality and morbidity. Stent collapse is one of the complications that can occur in this type of treatment. The aim of this article is to analyze the expected cause of stent collapse and to draw attention to the importance of the surveillance follow-up, as this phenomenon may occur late postdeployment. Methods A retrospectively collected dataset from the two highest volume trauma centers in Saudi Arabia was analyzed between April 2007 and October 2012. A total of 66 patients received stent grafts for traumatic aortic injury and were included in the study. We apply Ishimaru's anatomical aortic arch zones and Benjamin's aortic injury grading systems. There were 35 patients with aortic injury at zone 2, 26 patients in zone 3, and 5 patients in zone 4. About 96% (63) of the injuries were grades 2 and 3, including large intimal flap or aortic wall pseudoaneurysm with change in wall contour. The technical success rate, as defined by complete exclusion of lesions without leaks, stroke, arm ischemia or stent-related complications, was 90%. Results Proximal stent collapse occurred in 4.5% of patients (3 of 66 inserted stents) during follow-up of 4 to 8 years (mean, 6 years). Patients with stent collapse tended to have an acute aortic arch angle with long-intraluminal stent lip, when compared with patients with noncollapsed stents. Intraluminal lip protrusion more than 10-mm increased collapse (p < 0.001). Stent-grafts sizes larger than 28 mm also demonstrated a higher collapse rate (p < 0.001). Conclusions The risk of stent collapse appears related to poor apposition of the stent due to severe aortic arch angulation in young patients and to large stent sizes (>28 mm). Such age groups may have more anatomical and aortic size changes during the growth. Clinical and radiological surveillance is essential in follow-up after stent-graft treatment for traumatic aortic injury.

Objectives Endovascular repair (ER) of popliteal artery aneurysm (PAA) is an alternative to open repair. However, there is no standardized protocol for when to opt for ER and the decision is therefore at the discretion of the clinician. This study aims to evaluate the adherence to the Instruction For Use (IFU) in patients undergoing ER for PAA and factors associated with stent graft patency at one year. Methods The adherence to IFU provided by the manufacturer in 55 patients treated with Gore Viabahn® Endoprosthesis with Heparin Bioactive Surface for PAA between 2009 and 2019 were retrospectively analyzed. Duplex follow-up was performed at 30 days and one year. Results The two groups of patients treated within ( n = 10) and not within ( n = 45) IFU did not differ in patient demographics, diagnostic assessment, treatment or outcome. Forty-five patients (81.8%) received stent graft placement with at least one deviation according to IFU. Distal oversizing >20% was the most frequent deviation against IFU ( n = 22, 40.0%). Primary patency at one year was 72%. Diameter size difference >1 mm between overlapping stent grafts (6/14 [43%], p = 0.013) and renal insufficiency (5/12 [42%], p = 0.0086) were associated with lower primary patency at one year. Age-adjusted analysis of tortuosity index (HR 1.78/SD, 95% CI 1.17–2.71; p = 0.0071) and maximal PAA angle (HR 1.73/SD, 95% CI 1.018–2.95; p = 0.043) were associated with major amputation/mortality at end of follow-up. Conclusion The majority of patients undergoing ER for PAA were not treated within IFU. Diameter size difference >1 mm between overlapping stent grafts was associated with a higher loss of primary patency at one year. Multi-center studies with larger sample size and long-term follow up of patency are warranted.

Purpose: To report the consequences of endoluminal deployment of stent-grafts in the thoracic aorta with intentional occlusion of the left subclavian artery. Case Reports: Three patients with an aortic type-B dissection and 1 with a thoracic aneurysm were treated endoluminally with Talent stent-grafts implanted over the ostium of the left subclavian artery without prior surgical subclavian-carotid transposition. The primary intimal tears were sealed and the degenerative aneurysm excluded; blood pressure in the left arm was significantly diminished immediately after the stent-graft was released, but adequate collateral retrograde perfusion via the left vertebral artery was apparent in all patients. No neurological deficit and no symptoms of left arm ischemia were observed in a follow-up that ranged from 14 to 20 months. Conclusions: Our limited experience shows that occlusion of the left subclavian artery with a stent-graft is well tolerated. If ischemic symptoms occur, a transposition procedure can be performed on an elective basis.
