Use of Multilayer Stent and Fenestrated Endograft in a Single Session to Treat Long-Segment Aorta.

A 72-year-old man with suprarenal aneurysm and 2 large penetrating ulcers (PAUs) in the descending aorta was referred for endovascular treatment. To avoid long-segment aortic coverage and the attendant risk of spinal ischemia, combination of 2 different stent technologies was used. A multilayer flow modulator was implanted in the thoracic aorta for the PAU, followed by implantation of a customized 4-vessel fenestrated stent graft for the suprarenal aneurysm.

The V-Block Occlusion Stent and Sclerotherapy Device for Varicose Vein Treatment: A Retrospective Analysis.

Background: The procedure aims to show our results with a novel nontumescent, nonthermal technique to treat varicose veins. The V-block occlusion stent is a minimally invasive device for treating reflux of the great saphenous vein (GSV). It is an office-based procedure that does not require tumescence anesthesia.

Contemporary strategies for repair of complex thoracoabdominal aortic aneurysms: real-world experiences and multilayer stents as an alternative.

Thoracoabdominal aortic aneurysms (TAAA) present special challenges for repair due to their extent, their distinctive pathology, and the fact that they typically cross the ostia of one or more visceral branch vessels. Historically, the established treatment for TAAA was open surgical repair, with the first procedure reported in 1955. Endovascular repair of TAAA with fenestrated and/ or branched endografts, has been studied since the beginning of the current century as a means of mechanical aneurysm exclusion.

Developments in parallel grafts for aortic arch lesions.

Due to the shortage of commercially available off the shelf aortic arch grafts since the last years parallel grafts or chimney grafts have played an increasing role in the treatment of patients with aortic arch lesions. Although there are still issues with type endoleaks and gutters between the chimney graft and the aortic stent-graft remaining. We report our results with the Medtronic thoracic graft in combination with long self-expanding parallel grafts, to ensure an overlapping zone of more than 7 cm between the different grafts.

Experience with the sandwich technique in endovascular thoracoabdominal aortic aneurysm repair.

Background: The sandwich technique is an endovascular off-the-shelf solution for patients with thoracoabdominal aortic aneurysms (TAAAs). In a sandwich configuration, the chimney stent runs in the middle of a space created by two or three aortic endografts.

Methods: All patients with TAAAs who were treated with the sandwich technique were included in the study.

Safety and feasibility of a novel transcervical access neuroprotection system for carotid artery stenting in the PROOF Study.

Background: Randomized controlled trials have shown that periprocedural rates of stroke and death are higher with carotid artery stenting (CAS) than with carotid endarterectomy (CEA) in the treatment of carotid artery stenosis. Diffusion-weighted magnetic resonance imaging (DW-MRI) has shown higher rates of clinically silent new ischemic brain lesions when CAS is performed as compared with CEA. The Silk Road Medical Embolic PROtectiOn System: First-In-Man (PROOF) Study is a single-arm first-in-man study using the MICHI Neuroprotection System (Silk Road Medical Inc, Sunnyvale, Calif), a novel transcervical access and cerebral embolic protection system.

Endovascular management of ascending aortic pathology.

Background: Endovascular treatment of the ascending aorta is particularly challenging because of the anatomic features of this aortic segment. Only patients without connective tissue disorders, clinically relevant aortic regurgitation or stenosis, or concomitant coronary artery disease can be considered for an endovascular procedure. We report our results in a series of patients with aneurysms or intramural hematoma, penetrating ulcers, or floating thrombus who were scheduled for stent grafting.

A total laparoscopic technique for endovascular thoracic stent graft deployment.

Background: Limitations of endovascular thoracic aneurysm treatment include small, tortuous, or severely calcified iliac arteries. We present our experience with a total laparoscopic access to deploy thoracic endografts.

Methods: A total laparoscopic left retrocolic approach was used in all cases.

Laparoscopic surgery in the management of complex aortic disease: techniques and lessons learned.

Laparoscopic vascular surgery must be assessed in the context of both open and endovascular interventions. The development of improved laparoscopic equipment and endoscopic techniques makes performance of laparoscopy easier, but endovascular interventions still hold wide appeal because they are minimally invasive and are easier to master by vascular surgeons. Despite decreased morbidity and recovery time, endovascular interventions have inferior durability and higher reintervention rates when compared with open aortoiliac interventions.

Protected carotid artery stenting and angioplasty via transfemoral versus transcervical approaches.

This prospective cohort study was taken to determine whether transcervical carotid artery stenting (CAS) with internal carotid artery (ICA) flow reversal is associated with a lower incidence of embolization and femoral access complication when compared with protected, transfemoral CAS in selected, high-risk patients. From 2002 to October 2004, the authors performed 55 carotid stentings and angioplasties. Among the 24 cases via transfemoral approach, 1 developed transient ischemic attack (TIA), 1 stroke, 1 asystolic cardiac arrest, 2 groin hematoma, 2 technical failure, and 1 restenosis.
