Comparison of outcomes for short-neck and juxtarenal aortic aneurysms treated with the Nellix endograft versus conventional endovascular aneurysm sealing.

Objective: The objective of this study was to evaluate the results of the off-label use of the Nellix endograft (Endologix, Irvine, Calif) for the treatment of short-neck aneurysms and juxtarenal aortic aneurysms (JAAs) compared with the outcomes of patients with infrarenal abdominal aortic aneurysms treated in accordance with the manufacturer's instructions for use.

Methods: Data available from patients treated with the Nellix endograft from September 2013 to January 2016 were reviewed to create a case-control analysis (1:2). Fourteen elective patients with a short-neck aneurysm or JAA (<10 mm) and mild aortic neck angulation (<35 degrees) were included.

Increasing efficacy of endovascular recanalization with covered stent graft for TransAtlantic Inter-Society Consensus II D aortoiliac complex occlusion.

Objective: We compared the outcomes and the durability of endovascular recanalization (EVR) with the Viabahn (W. L. Gore and Associates, Flagstaff, Ariz) covered stent graft vs traditional aortobifemoral or aortofemoral bypass grafting for complex aortoiliac occlusions.

U Stent-Graft Technique as a Treatment for Homolateral Metachronous Common Iliac and Internal Iliac Arteries Aneurysms after Open Surgery.

We report a case of a metachronous common iliac artery and the internal iliac artery (IIA) aneurysm developed 8 years after an aortobi-femoral bypass for treatment of abdominal aortic aneurysm associated at chronic occlusion of the right iliac axis. To exclude the metachronous aneurysm on the left iliac axis and to maintain the pelvic circulation, an external to IIA endografts were positioned ("U stent-graft technique"). At 6-month follow-up, the computed tomography scan showed patency of the endografts, of the bypass and of the IIA, without endoleak, or other adverse events.

The First Case of a Nellix Sac-Anchoring Endoprosthesis Removal for Aortoenteric Fistula.

The Nellix device (Endologix, Irvine, CA), has been designed with a brand new concept to seal the abdominal aortic aneurysms, minimizing endoleaks and reducing reinterventions. We present the first open conversion of a Nellix endograft due to aortoduodenal fistula of a 74-year-old male patient treated for an abdominal aortic aneurysms of 62-mm diameter.

Abdominal aortic endograft collapse due to false lumen radial force of an acute type B aortic dissection.

We report a case of abdominal endograft proximal collapse due to acute type B aortic dissection in a patient previously treated with endovascular repair (EVAR) for an infrarenal abdominal aortic aneurysm. Patient underwent axillobifemoral bypass grafting, in emergency. The postoperative computed tomography scan showed reexpansion of the occluded endograft.

Fungal infection of aortic Endograft because of Aspergillus fumigatus.

A 59-year-old male, referred to our center with a ruptured aortic aneurysm, underwent urgent endovascular repair and femoro-femoral crossover bypass. An endograft infection because of Aspergillus fumigatus occurred about 20 days after surgery. We removed the endograft and femoral prosthesis and we then performed an aorto-bi-iliac bypass with autogenous reversed superficial femoral veins.

Aortic arch rupture after multiple multilayer stent treatment of a thoracoabdominal aneurysm.

Despite the improvement in diagnostic and therapeutic strategies, the treatment of thoracoabdominal aneurysms is still burdened with a high incidence of peri/postoperative morbidity and mortality. The multilayer flow modulator is a new and promising technique for the treatment of such disease; however, some limits are still evident. We report the case of a 76-year-old woman affected by a symptomatic thoracoabdominal aneurysm treated with multiple Cardiatis multilayer flow modulators complicated by aortic arch rupture on the fifth postoperative day, with subsequent patient death.

A retrospective study on early carotid endarterectomy within 48 hours after transient ischemic attack and stroke in evolution.

Background: Large randomized controlled trials have shown that carotid endarterectomy (CEA) is beneficial in the treatment of recent severe symptomatic carotid stenosis. Data are lacking concerning the risks of early CEA (<48 hours) for stroke in evolution (SIE) or crescendo transient ischemic attack (CTIA). The primary end point of this retrospective study was to evaluate the incidence of stroke, major adverse cardiac events (MACEs), and death within the first 30 days after early CEA performed within 48 hours in patients presenting with transient ischemic attack (TIA)/SIE.

Open conversion after endovascular aortic aneurysm repair: a single-center experience.

Background: The endovascular treatment of an abdominal aortic aneurysm (AAA) is a treatment with low risk and good reported results. This retrospective study analyzed experience with patients requiring surgical conversion after endovascular abdominal aortic aneurysm repair (EVAR).

Methods: A total of 26 patients underwent open conversion (OC) after EVAR (18 endografts implanted at the authors' center and 8 in other centers).

Disconnection of multilayer stents 2 years after treatment of a hepatic artery aneurysm.

Purpose: To report midterm failure of tandem peripheral multilayer stents used to treat a common hepatic artery aneurysm (HAA) that had a good early result.

Case Report: A 71-year-old man with multiple comorbidities had a 3.4-cm HAA treated with 2 Cardiatis peripheral multilayer stents (8×100 and 9×60 mm) that overlapped by 3 cm.

Migration of an AMPLATZER atrial septal occluder to the abdominal aorta.

Percutaneous closure of an atrial septal defect has been increasingly used, and complications have been rare. We report the case of a 63-year-old man who had undergone endovascular closure of a secundum atrial septal defect months earlier. The occluder was later found in the abdominal aorta.

Symptomatic aneurysm of a perforating peroneal artery after a blunt trauma.

A 48-year-old woman was referred to us for a pulsatile and painful mass on the right leg after a trauma occurred 2 months earlier. The duplex scan revealed the presence of an aneurysm of the perforating peroneal artery. The patient underwent an endovascular coil embolization of the aneurysm.

Acute management of aortoesophageal fistula and tracheoesophageal fistula treated by thoracic endovascular aortic repair and esophageal endoprosthesis: a case misdiagnosed as esophageal cancer.

Aortoesophageal fistula is rare but fatal if untreated. Open thoracic surgery is associated with high operative mortality and morbidity. We report a case of a 77-year-old man who, treated with thoracic endovascular aortic repair (TEVAR) for descending thoracic aneurysm in another center, after an acute episode of hematemesis and melena was referred to our center.

Endovascular treatment of hepatic artery aneurysm by multilayer stents: two cases and one-year follow-up.

We wished to analyze our initial experience with the Cardiatis Multilayer Stent for visceral artery aneurysms. Two males with a hepatic artery aneurysm (34 mm and 48 mm in diameter, respectively) were treated, via a percutaneous femoral approach, with multilayer stents. We deployed the stent in front of the aneurysm neck, covering the hepatic artery branches.

Visceral artery aneurysms, an experience on 32 cases in a single center: treatment from surgery to multilayer stent.

Between 2000 and 2010, 32 patients (17 males; mean age: 64.7 [range: 18-85] years) with visceral artery aneurysms (VAAs) were treated in our center. The site of aneurysmal disease was: splenic artery (18), hepatic artery (5), superior mesenteric artery (3), pancreaticoduodenal artery (3), celiac axis (2), and gastroduodenal (1).

Is total debranching a safe procedure for extensive aortic-arch disease? A single experience of 27 cases.

Objective: Thoracic, arch, and proximal descending thoracic aorta diseases are still considered an enormous challenge. The hybrid approach developed in recent years (supra-aortic trunks debranching and thoracic endovascular repair aortic repair; TEVAR) may improve the morbidity and mortality of the population at risk. The aim of this study was to analyze retrospectively our experience in the hybrid treatment of aortic-arch aneurysms and dissections.

Endovascular treatment of a symptomatic mycotic aneurysm of the peroneal artery.

A 69-year-old man was referred to our facility owing to the sudden onset of a compression-like pain in the right leg, without limb-threatening acute ischemia. The duplex scan examination, followed by a selective leg angiography, showed the presence of a peroneal artery aneurysm. A diagnosis of mycotic aneurysm was made on the basis of the patient's clinical condition, positive blood cultures, and the unusual location of the lesion.

Management and urgent repair of ruptured visceral artery aneurysms.

Five patients were treated for ruptured visceral artery aneurysms during the last 9 years, including two splenic and three pancreaticoduodenal aneurysms. The average size of aneurysm was 2.6 cm (range: 1.

Free-floating thrombus in the internal carotid artery: diagnosis and treatment of 16 cases in a single center.

Background: Free-floating thrombus in the internal carotid artery (FFT-ICA) is a rare condition and its real incidence is unknown. The most common etiology is a complication of an atherosclerotic plaque, but several medical conditions can be responsible. The purpose of this study was to retrospectively analyze our experience with carotid endarterectomy in the management of FFT-ICA and also to analyze the patient outcome.

Aneurysm of the aberrant right subclavian artery: surgical and hybrid repair of two cases in a single center.

The aberrant right subclavian artery (ARSA) aneurysm is rare; however, the risk of rupture and thromboembolism is high, with a postrupture mortality rate of 50%. In this report, we have described two cases of this anomaly. In the first case, a 62-year-old male patient presented with a symptomatic aneurysm of ARSA (maximum diameter of 4 cm) causing chest pain with dyspnea during moderate physical effort.

Parkes-Weber syndrome and giant superficial femoral artery aneurysm. Treatment by endovascular therapy and follow-up of 8 years.

Congenital vascular malformations represent a wide number of diseases with a great variability of clinical features. The association between congenital vascular malformations and peripheral aneurysms is very rare. The present study reports a case of giant superficial femoral artery aneurysm (7-cm-long) associated with Parkes-Weber syndrome (capillary malformation, multiple arteriovenous fistulas [AVFs], skeletal hypertrophy of the affected limb) treated by positioning two covered self-expandable endoprostheses after embolization of AVFs with Gianturco coils.

Early carotid surgery in patients after acute ischemic stroke: is it safe? A retrospective analysis in a single center between early and delayed/deferred carotid surgery on 285 patients.

Background: The early risk of stroke after transient ischemic attack (TIA)/stroke is of the order of 5-10% at 1 week and 10-20% at 3 months. Even if carotid endarterectomy (CEA) is the treatment of choice in symptomatic internal carotid artery stenosis, the timing of carotid intervention after acute stroke is not yet codified. The authors want to determinate whether early CEA is safely carried out in the first few hours (<48 hours) successive to the nondebilitating neurological event and whether the outcome (TIA/stroke/death) in these cases is comparable with the results of those treated by delayed/deferred surgery (range, 48 hours-24 weeks).

Carotid endarterectomy: comparison between general and local anesthesia. Revision of our experience with 428 consecutive cases.

Background: This sequential retrospective monocentric study compares the results between general and local anesthesia for carotid endarterectomy (CEA).

Methods: Between November 2002 and October 2004, 428 CEAs were performed in our vascular unit. Two groups were formed: group GA (general anesthesia): 219 patients operated under general anesthesia; group LA (local anesthesia): 209 patients operated under local anesthesia.
