Endovascular treatment of thoracic aortic aneurysms [Torasik aort anevrizmalarinda endovasküler tedavi]

The morbidity and mortality rates of conventional surgery for the extensive distal aortic lesions are relatively high. Stent-grafting has been widely used for the diseases of the distal thoracic and abdominal aorta. However, endoleaks, and visceral and spinal cord ischemia due to coverage of critical branches of the distal aorta are major concerns related to this technique. The outcome mostly depends on the proper placement of the proximal part of the graft. Anatomical features of the aneurysmal aorta are the main cause of complications of the stent-grafts

Tirofiban rescue in acute carotid stent thrombosis despite a standard antiplatelet regimen - A case report

WOS: 000231873100014Fifty minutes following implantation of a right internal carotid artery stent, left lower extremity paresis developed in a patient despite use of heparin, clopidogrel and aspirin. Immediate angiograms revealed partially thrombosed carotid stent, then tirofiban (a glycoprotein IIb-IIIa receptor inhibitor) was administered intraarterially into the stent. After 15 minutes, complete resolution of the thrombus was detected on repeat angiography. The patient had recovered completely at 30-day follow-up

Large pseudoaneurysm of the carotid artery: In Behçet's disease

PubMed ID: 15902833Behçet's disease is a multisystem inflammatory disease of unknown cause. Its major pathologic feature is vasculitis. We report the occurrence of a large pseudoaneurysm of the carotid artery in a patient who had Behçet's disease. The patient underwent surgery and was discharged on the 7th postoperative day. Ours is only the 4th such case reported in the English-language medical literature. Endovascular and surgical options are discussed herein. © 2005 by the Texas Heart® Institute, Houston

Does endovascular repair affect aortic remodeling in acute complicated type B aortic dissection?

Background: This study aims to analyze the volume changes of true and false lumens at a late stage in patients undergoing thoracic endovascular aortic repair (TEVAR) due to acute complicated type B aortic dissection. Methods: B etween M arch 2 006 a nd N ovember 2 012, 1 8 consecutive patients (14 males, 4 females; mean age was 61.9±11 years; range 39 to 77 years) who underwent TEVAR for acute complicated type B aortic dissection in our clinic were included in this study. Computed tomography scans obtained at the final visit were used for the volume analysis of true and false lumens. The median follow-up was 35.3 (range, 12 to 84) months. Indications for intervention were rupture or malperfusion in 17 patients (both in some patients) and persistent chest pain in one patient. The stent-graft part of the descending thoracic aorta (DTA) was defined as Segment 1, DTA without stent-graft (supraceliac) as Segment 2, and the abdominal aorta as Segment 3. Results: In segment 1, the mean volume of true lumen increased from 74.4±49 mL to 110±50 mL (p=0.0145), while the mean volume of false lumen decreased from 124.2±81 mL to 59.5±59 mL (p<0.00001). In segment 2, the mean volume of true lumen increased from 23.1±28 mL to 40.5±33 mL (p=0.0015), while the mean volume of false lumen decreased from 32.8±29 mL to 29±1 mL (p=0.624). In segment 3, the mean volume of true lumen increased from 46.5±63 mL to 57.3±74 mL (p=0.0388), the mean volume of false lumen decreased from 41.8±30 mL to 37.6±32 mL (p=0.5195). True and false lumens volume changes were statistically significant except volume decrease in segment 3. Conclusion: Endovascular repair of type B aortic dissection may positively affect aortic remodeling in chronic settings and may prevent possible aorta-related complications during longterm follow-up
