OBJECTIVE: Endovascular aneurysm repair (EVAR) has progressively expanded to treat more challenging anatomies. Although EVAR in patients with wide infrarenal necks has been reported with acceptable results, there is still controversy regarding the longer-term outcomes. Our aim is to determine the impact of infrarenal neck diameter on midterm outcome following EVAR with a single endograft with suprarenal fixation. METHODS: A retrospective case-control study was designed using data from a prospective multicenter database...

The rising use of endovascular techniques utilizing femoral artery access may increase the frequency with which surgeons face the challenge of hernia repair in reoperative groins-which may or may not include a vascular graft. We present a case where a vascular graft contributed to an acute presentation and complicated dissection, and review the literature. A 67-year-old man who had undergone prior endovascular aneurysm repair via open bilateral femoral artery access and concomitant prosthetic femorofemoral bypass, presented with an incarcerated, scrotal inguinal hernia...

Purpose Percutaneous remote access for endovascular aortic repair is an advantageous alternative to open access. Previous surgery in the femoral region and the presence of synthetic vascular grafts in the femoral/iliac arteries represent major limitations to percutaneous remote access. The aim of this study was to evaluate an original technique used for enabling percutaneous remote access for thoracic or abdominal endovascular aortic repair in patients with scar tissue and/or a vascular graft in the groin. Methods Twenty-five consecutive patients with a thoracic (11/25; 44%) or an aortic aneurysm (14/25; 66%) and with a synthetic vascular graft in the groin (16/25; 64%) or a redo groin access (9/25; 36%) were managed through the percutaneous remote access...

Endovascular surgery represents a minimally invasive procedure for the treatment of occlusive and aneurysmal arterial disease. However, it is followed by inflammatory response, with a rise in specific inflammatory biomarkers, such as C-reactive protein, serum amyloid A and fibrinogen. Shear stress during balloon inflation and vascular injury represents triggering events for the inflammatory process, stimulating the production of proinflammatory molecules and activation of circulating monocytes. The current literature indicates that stent implantation induces more prominent inflammatory reaction...

Renal artery aneurysm (RAA) rupture during pregnancy is a rare but life-threatening event and few cases have been reported in literature. Currently the best approach, endovascular or surgical, seems to be under discussion. A case of a 31-year-old woman with a symptomatic right RAA detected three days after childbirth is reported. A successful endovascular repair by a covered stent-graft was performed.

We conducted this study to determine the risk of transmission of Q fever to health care workers (HCWs) during perioperative exposure to Coxiella burnetii-infected thoracic endovascular aneurysm stent graft. Pre-operative and 6-week post-operative phase I and II IgG Q fever antibody titers were determined in 14 staff members of an operation room. The room had a negative pressure and all the members of the surgical team wore either a fitted N-95 mask or a powered purified air respirator. Phase I and II IgG antibody titers were <1:16 for 11 of the 14 studied HCWs; 2 HCWs did not follow up at 6 weeks and 1 had a pre-exposure phase II IgG titer of 1:128 with no change 6 weeks later...

Acute aortic dissection is a challenging disease to manage. Type B aortic dissection has traditionally been divided temporally into acute and chronic cases but more recently this classification has been modified to include a sub-acute phase. Computed tomography is the imaging technique used most frequently in diagnosis and management. Active management of blood pressure is essential and should include beta-blockade unless contra-indicated. In-hospital outcomes are generally acceptable in patients with medically managed acute uncomplicated type B aortic dissection, with up to 90% of patients surviving to hospital discharge but by 5-years up to 50% of patients are dead with a significant proportion dying from aortic rupture...

OBJECTIVES: Endovascular repair of traumatic injury of the aortic isthmus is a safe technique that has shown good short-term results. However, the future of these stent grafts remains unexamined, especially in relation to young patients. METHOD: Between January 2000 and December 2014, 60 patients were treated with endovascular aortic stent graft for injury of the aortic isthmus. Follow-up was done by computed tomography scans with intravenous contrast or magnetic resonance imaging associated with a chest X-ray in order to control the stent graft...

OBJECTIVES: To quantify the impact of thoracic endovascular aortic repair (TEVAR) on radial aortic strain with the aim of elucidating stent-graft-induced stiffening and complications. METHODS: Twenty fresh thoracic porcine aortas were connected to a mock circulatory loop driven by a centrifugal flow pump. A high-definition camera captured diameters at five different pressure levels (100, 120, 140, 160, and 180 mmHg), before and after TEVAR. Three oversizing groups were created: 0-9% (n = 7), 10-19% (n = 6), and 20-29% (n = 6)...

OBJECTIVES: We aimed to develop a simple, reliable, and timesaving technique for the therapy of thoracoabdominal aortic (TAA) aneurysms that are not suitable for endovascular repair. METHODS: In this pilot study, we sought to combine the advantages of classic open vascular procedure with the use of endoscopic surgical tools and small skin incisions to develop a minimally invasive approach for TAA replacement. The following procedures were used: endoscopic exposure and closure of the lower intercostal arteries; small posterolateral thoracotomy and left retroperitoneal incisions to expose the anastomotic regions of the aorta; partial anticoagulation; passive bypass and sequential aortic clamping; tunnelling of the graft through the native aortic lumen (endoaneurysmorrhaphy) and open performance of vascular anastomosis...

Endovascular repair has revolutionised the emergency treatment of thoracic aortic disease. We report our 10 year experience using this treatment in emergency cases. A prospectively maintained vascular database was analysed. Patients' medical records and CT images stored on the hospital PACS system were also reviewed. Statistical analysis was done using IBM SPSS V21. There were a total of 59 thoracic aortic stenting procedures of which 33 (60% males with a mean age of 58 yrs) were performed for emergency thoracic pathologies: traumatic transection (n = 10), ruptured aneurysm (n = 6), non-traumatic dissection (n = 8) and penetrating aortic ulcer (n = 9)...
