Improved technique for sheath supported contralateral limb gate cannulation in endovascular abdominal aortic aneurysm repair

2019

Summary: Background: To present a technique of sheath supported contralateral limb gate (CLG) cannulation of modular bifurcated stent-graft in endovascular abdominal aortic repair. Materials and methods: After totally percutaneous bilateral femoral access, the 9F introducer sheath is exchanged to a 30 cm 12 fr introducer sheath over a stiff wire contralateral to the intended main stent-graft insertion side and advanced into the aorta below the lowest renal artery. Parallel to the stiff wire within the sheath an additional standard J-tip guidewire with a 5 fr Pigtail angiographic catheter is advanced to the level of the renal arteries. After main body deployment, the 12 fr introducer sheath…

New 3-zone hybrid graft : First-in-man experience in acute type I dissection

2019

Abstract Objective Acute type I aortic dissection (AAD) represents a surgical emergency with time-dependent evolving complications. Frozen elephant trunk (FET) enables false lumen exclusion downstream but is still debated in AAD due to its greater dimension of surgery. To combine the benefits of fast proximal repair with the FET benefits, a 3-zone hybrid graft was developed consisting of an ascending polyester portion, an arch noncovered stent, and a descending stent graft. Mid-term results of this new technique are presented. Methods A total of 6 patients (age mean 69 years) with type I AAD in critical status (Penn classification B n = 5, BC n = 1) were operated between July 2016 and April…

Symptomatic atherosclerotic occlusive disease of all supra-aortic arch vessels treated with total aortic arch rerouting.

2011

We present an uncommon case of symptomatic atherosclerotic occlusive disease of all supra-aortic arch vessels and its surgical treatment by total aortic arch rerouting after endarteriectomy of all target vessels.

Aortic valve-sparing root replacement from inside the aorta using three Dacron skirts preserving the native Valsalva sinuses geometry and stabilizing…

2009

We present an alternative idea for valve-sparing technique combining the advantages of the reimplantation and the benefits of the remodeling techniques. We replace the sinuses of Valsalva using three Dacron skirts from inside of the aorta. The physiological anatomy of the Valsalva sinuses and their dynamic properties are preserved and the aortic commissures displacement avoided. The distal rim of each Dacron skirt was anchored to the aorto-ventricular junction using Ticron (2-0) U stitches placed from the ventricular side to the aortic side. We stabilize the base of the aortic annulus to prevent future dilation.

External reinforcement of varicose veins with PTFE prosthesis in infrainguinal bypass surgery -- clinical results.

2003

OBJECTIVE Segmental varicose degeneration of the autogenous greater saphenous vein may limit its use in infrainguinal bypass surgery. Wrapping a PTFE prosthesis around dilated veins has emerged as an option to create externally reinforced vein bypasses. Results regarding graft patency and limb salvage were analyzed. METHODS Between September 1995 and January 2001, 35 infrainguinal bypass operations in 33 patients were performed with greater saphenous veins exhibiting segmental varicose dilatation. Grafts were followed by duplex scan and retrospective analysis of graft patency and limb salvage was performed. RESULTS One bypass prompted successful revision for early occlusion. Four bypasses r…

Retroaortic left renal vein and inflammatory abdominal aortic aneurysm

2010

The aim of this study was to report successful surgical management of an inflammatory abdominal aortic aneurysm associated with a retroaortic left renal vein. The patient, a 78-year-old man, presented with diffuse abdominal pain, fever, and constipation. Contrast-enhanced computed tomography showed soft tissue surrounding the aneurysm and a left renal vein behind the aorta. Intraoperative findings confirmed the CT images. The patient is alive and well 6 months postoperatively.

Efficacy of TachoSil patches in controlling Dacron suture-hole bleeding after abdominal aortic aneurysm open repair

2009

Abstract Purpose The aim of this study is evaluate the efficacy of TachoSil® patches in controlling suture-hole bleeding after elective infrarenal abdominal aortic aneurysm (AAA) replacement with Dacron graft. Materials and methods Patients undergoing elective replacement of infrarenal AAA with Dacron grafts were prospectively randomized to TachoSil® patches (Group I) or standard compression with surgical swabs (Group II). We evaluated time to haemostasis, blood loss during the operation, blood loss after cross-clamp removal, duration of operation, drain volume, requirement for blood transfusion and surgeons rating of efficacy. Results Twenty patients were randomized (10 patients in each tr…

German registry for acute aortic dissection type A (GERAADA)--lessons learned from the registry.

2010

A German registry for acute aortic dissection type A (GERAADA) was initiated by the Working Group for Aortic Surgery and Interventional Vascular Surgery of the German Society for Thoracic and Cardiovascular Surgery (GSTCVS) in July 2006. This web-based database was developed to record the data of patients who had undergone surgery for aortic dissection type A. From analyzing the data, we aim to learn how to improve surgical treatment and to identify parameters affecting patient outcome. In the beginning, 33 cardiac centers participated via online access to the registry on the GSTCVS' homepage. Since then, 43 centers in Germany, Switzerland and Austria have begun entering data on the pre- an…

Strategies for endovascular aortic repair in aortobronchial and aortoesophageal fistulas.

2013

Objective To report our experience of thoracic endovascular aortic repair (TEVAR) for acute bleeding originating from the thoracic aorta in patients with aortobronchial fistula (ABF) or aortoesophageal fistula (AEF). Patients and Methods A total of nine patients (three woman) were treated from September 1995 to March 2012 by TEVAR for ABF (n = 5) and AEF (n = 4). The implants (N = 14) were introduced with fluoroscopic guidance via the aorta (n = 1), the iliac (n = 2), or femoral (n = 11) artery, respectively. Results All aortic lesions could be sealed successfully. Perioperative morbidity was 0% in the ABF group and 50% (2 of 4) in the AEF group and no procedure-related morbidity was noted …
