We report a case of pseudoaneurysm formation after implantation of Medtronic Freestyle stentless bioprosthesis with a full root technique. A 65-year-old man previously underwent aortic root replacement with a Freestyle bioprosthesis. Ten years after the initial operation, pseudoaneurysm of the aortic root with a diameter of 6 cm was observed by computed tomography. At the reoperation, there was no sign of infective endocarditis, and the pseudoaneurysm was found to originate from the ruptured left and noncoronary sinuses...

In-stent restenosis (ISR) is the most common long-term complication following Carotid Artery Stenting (CAS), affecting 3.5% to 21% of patients after a mean follow up of 18 months in published reports. Until now, the optimal management for ISR after CAS is still not clear and different endovascular treatments along with various surgical options have been proposed. Moreover, surgical treatment for ISR in a previously operated patient of ipsilateral endarterectomy is a technically demanding procedure. In this report, we describe a case of severe carotid recurrent ISR, which occurred after CAS for post-endarterectomy restenosis, that was successfully treated, in a straightforward way, with a carotid bypass using a Gore(®) Hybrid Vascular Graft...

After Thoracic Endovascular Aortic Repair (TEVAR) for chronic type B aortic dissection (cTBD) the patency of the false lumen is quite common and its presence is associated with the risk of developing complications and is a predictor of death by aortic rupture. We report a case of a patient treated in emergency for the rupture of the false lumen in cTBD. He had previous TEVAR with persisting distal dissection and retrograde reperfusion of the false lumen. We performed an original endovascular treatment with graft relining and false lumen occlusion with a home-made "candy plug" obtained with two commercially available stent grafts...

OBJECTIVES: High-mobility group box 1 (HMGB-1) is a key substance mediating inflammation and development of atherosclerotic lesions (AL), including abdominal aortic aneurysms (AAA). Serum levels of HMGB-1 are increased in patients with AAA than in normal controls because the ALs in AAAs secrete HMGB-1. We therefore postulate that the serum HMGB-1 level should decrease after endovascular aortic repair (EVAR) or open aortic repair (OAR). However, there is no evidence of this in the literature...

We report a case of a compassionate treatment of a ruptured thoraco-abdominal aortic aneurysm in a 92-year-old patient. Patient was admitted to our emergency department for acute onset of pain irradiating to the back. Computed tomographic angiography showed the presence of a thoraco-abdominal aortic aneurysm with a contained rupture at infrarenal level. Given of the presence of a relative healthy visceral aorta, we decided to treat the patient by Ovation(®) (Endologix, Irvine, CA - USA) implantation in an off-label fashion...

PURPOSE: Chronic traumatism of the common femoral artery due to intravenous injection in drug abusers, in association with local infections and arterial wall weakening caused by HIV, can lead to the development of pseudoaneurysms. Rupture of pseudoaneurysm is a dramatic event in such patients and its correction is difficult and controversial. Most of the cases reported describe open surgical elective options, that consist in ligation, repair or substitution of the damaged arterial segment, employing when possible biological grafts...

PURPOSE: to describe the use of the combination of a conical custom-made TREO® (TREO CM) stent-graft in the treatment of a saccular abdominal aortic endograft (AAA) with long but tight and calcified distal neck. TECHNIQUE: A 65-year female patient was treated for a saccular 5.2 cm AAA with a 3cm-long but calcified and tight (16mm) distal neck, precluding the safe use of a bifurcated endograft. Since the patient refused an open surgery, a conical TREO CM endograft was manufactured with 20% proximal oversizing, whereas the 3cm caudal sealing segment demonstrated a conical configuration comprised of a 2cm and 1cm nitinol-supported zones of 20% and 10% oversizing, respectively, in order to avoid excessive strain and incomplete expand at the most distal calcified area, leading ultimately to an insidious infolding and consequent type Ib endoleak...

OBJECTIVE: This study aimed to investigate variation of blood flow to renal arteries in custom-made and pivot branch (p-branch) fenestrated endografting, using a computational fluid dynamics (CFD) technique. METHODS: Idealised models of custom-made and p-branch fenestrated grafting were constructed on a basis of a 26 mm stent graft. The custom-made fenestration was designed with a 6 mm diameter, while the 5 mm depth renal p-branch was created with a 6 mm inner and 15 mm outer fenestration...

Blunt subclavian artery injuries are rare and are associated with high morbidity and mortality. Several case reports have suggested that endovascular repair is safe with short operative times and minimal blood loss. We report a case of a 20-year-old male patient involved in a high speed motor vehicle collision that resulted in partial transection of left subclavian artery with complete luminal thrombosis. Patient also had a left main-stem bronchus avulsion along with major intra-abdominal injuries and multiple spine and long bone fractures...

BACKGROUND: Current guidelines suggest that coronary artery bypass grafting (CABG) should be the preferred revascularization method for unprotected left main coronary artery stenosis. In light of evidence from recent randomized trials, we assessed whether percutaneous coronary intervention (PCI) using drug-eluting stents is as safe and effective as CABG for the treatment of unprotected left main coronary artery disease. METHODS AND RESULTS: Digital databases and manual searches were performed for randomized trials comparing PCI and CABG for unprotected left main coronary artery stenosis...

Thoracic endovascular aortic repair (TEVAR) is an emerging treatment option for thoracic aorta aneurysms (TAA). Endovascular access is a challenge. We present a novel TEVAR technique in a patient with single kidney and a 6.4 cm TAA. Attempting to place a sheath through iliac arteries was unsuccessful. The decision to proceed to hybrid TEVAR was made. The protection of the solitary kidney was achieved through axillo-femoral bypass, followed by an end-to-side anastomosis between the aorta and a bifurcated graft...

Portal vein thrombosis (PVT) is a rare complication of liver transplantation which can lead to graft failure and patient death. Treatment can be difficult, especially in cases of PVT from the intrahepatic portal vein to the proximal jejunal veins. A 55-year-old woman had undergone living-donor liver transplantation with splenectomy for end-stage liver cirrhosis due to hepatitis C with hepatocellular carcinoma. Ten months after transplantation, massive ascites and slight abdominal pain developed, and computed tomography revealed a PVT between the intrahepatic portal vein and the superior mesenteric vein...

PURPOSE: To report a hybrid technique for the treatment of a suprarenal aortic aneurysm (SAA) in a patient with iliac occlusive disease. Initially an infrarenal aorto-bifemoral surgical graft was implanted, followed by deployment of a fenestrated bifurcated stent-graft at the suprarenal part of the aorta. CASE REPORT: A 69-year old man presented with a 51-mm saccular SAA and iliac occlusive disease with intermittent claudication. Both common iliac arteries had been previously treated with kissing stents...

PURPOSE: To present our early experience and highlight the technical difficulties associated with the use of fenestrated and branched stent-grafts to treat patients with juxta-, para-renal abdominal aortic aneurysms (AAA) and thoracoabdominal aortic aneurysms (TAAA). METHODS: A prospectively held database maintained at our department, was queried for patients who have undergone branched and fenestrated stent-grafting for AAA or TAAA treatment. Indication for repair, co-morbidity precluding open repair, technical challenges associated with the repair, as well as operative mortality, morbidity and re-intervention rate were evaluated...

BACKGROUND: Ovation Aortic Stent-Graft System is a new device for the endovascular treatment of Abdominal Aortic Aneurysms achieving fixation via a 35-mm long, rigid ancored suprarenal stent and sealing stent at the infrarenal level by a means of a polymer-filling pair of inflatable O-rings which cause narrowing of flow lumen and regional stenosis. Thus, concerns have been raised regarding hemodynamic consequences associated with this new desing . Our preliminary report showed no significant increase of aortic pulse wave velocity (aPWV) immediately after implantation of the Ovation in 3 patients...
