nitinol and Syndrome

Post-pneumonectomy syndrome is an unusual condition, that can occur a variable period of time after a patient has had a pneumonectomy. Management of this syndrome has been described using a number of different techniques, often with considerable mortality. We present a case report where this condition was treated successfully by insertion of an expandable Nitinol stent. This is the first time this technique has been described to treat this condition, and we feel it may be the procedure of choice in managing these patients.

Introduction-patients: Takayasu arteritis may involve various parts of the aorta and its major branches. It leads to occlusive or aneurysmal disease of the vessel. It can be treated either with surgery or percutaneous intervention. We report a successful endovascular treatment of stenosis of the descending thoracic and abdominal aorta in a 19-year-old female. Methods-results-conclusions: Self-expandable nitinol stent was deployed and adequate opening of the aorta was obtained in this patient. Long-term durability of endovascular approach is a matter of debate. We also reviewed the sufficiency of endovascular treatment versus surgery.

To evaluate the efficacy, tolerance, and outcomes of covered stents in the treatment of carotid blowout syndrome (CBS) in head and neck cancer patients.. Individual retrospective cohort study.. We retrospectively reviewed the medical and image files of all 20 consecutive head and neck cancer patients treated with covered stent grafts for CBS. Six acute, 12 impending, and two threatened cases of CBS were treated in patients who all had previously received radiation therapy. We evaluated the feasibility, hemostatic efficacy, survival without bleeding, and complications.. The etiologies of CBS were as follows: group 1, 13 carotid axis (common or internal carotid artery) pseudoaneurysms and one rupture; group 2, six patients with no identifiable source of bleeding on angiography but with a threatened carotid axis on computed tomography (CT). In all patients, a polytetrafluoroethylene-covered nitinol stent graft (Fluency; Bard/Angiomed GmbH & Co, Karlsruhe, Germany) was successfully placed. All of the stents were patent at the end of the procedure. Immediate hemostasis was achieved in the six hemorrhagic cases. Immediate transient ischemic attacks were observed in two patients, and carotid sinus syndrome was observed in one patient. Post-treatment bleeding was observed in five patients in group 2 and no patients in group 1. Survival without bleeding was 251 days in group 1 and 35 days in group 2. During follow-up, three asymptomatic stent thromboses occurred at a mean of 58 days.. Covered stent placement is highly feasible and proved effective without major complications in CBS due to carotid axis bleeding.

Carotid stump syndrome is one of the recognised causes of recurrent ipsilateral cerebrovascular events after occlusion of the internal carotid artery. It is believed that microemboli arising from the stump of the occluded internal carotid artery or the ipsilateral external carotid artery can pass into the middle cerebral artery circulation as a result of patent external carotid-internal carotid anastomotic channels. Different pathophysiologic causes of this syndrome and endovascular options for treatment are discussed.

The purpose of this study is to evaluate the multimodal treatment (thrombolysis, anticoagulation and surgical decompression) of subclavian-axillary vein thrombosis (Paget-Schroetter syndrome) and possibility of shortening of time of therapy.. In this paper 23 patients with Paget-Schroetter syndrome in Department of Vascular, General and Transplantological Surgery is presented. Thrombolysis with rt-PA, anticoagulation with heparin and intra venous angioplasty with the use intravascular stent, and operation with resection of the first rib in the treatment of subclavian vein thrombosis was used. During the follow up period the patients were divided into two groups: group I (13 patients) with traditional surgical decompression after 3-4 months (potential risk of hemorage) and group II (10 patients) with early surgical treatment (median 8 days). Long-term follow-up was obtained by chart review and asking patients to complete the DASH (Disabilities of the Arm, Shoulder and Hand) questionnaire that was developed by the American Academy of Orthopedic Surgeons.. Complete revascularization with venous thrombolysis was achived in all patients. Decompresion with transaxillary resection of first rib and venous revascularization were performed in the same procedure in all patients. Statistical difference were not found in both groups. Most patients report no disability of upper limb at work and sport activity.. Multimodal treatment of Paget-Schroetter syndrome (thrombolysis, the use of intravascular stents and early thoracic outlet decompression) can be used as a optimal of therapeutic method to subclavian vein thrombosis. The advantages of immediate surgical treatment are a promotion of rapid resumption of athletic activities.
