Surgical repair of thoracoabdominal aortic aneurysms (TAAA) is associated with significant morbidity and mortality. Hybrid approaches that involve visceral debranching and aortic endografting allow for an alternative approach in certain high-risk patients. In most circumstances the visceral vessels can be bypassed in a retrograde manner from the iliac arteries via a midline laparotomy, and the ...

Venous aneurysms are uncommon in the lower limb and are more frequently found in the neck and thoracic and visceral veins. However, they have been reported to cause thrombosis, pulmonary thromboembolism, and other related complications. Popliteal venous aneurysms are often undetected because they are usually asymptomatic, but they may cause pulmonary thromboembolic events. We experienced a case...

Degenerative aneurysms of the thoracic aorta are increasing in prevalence. The recognition of the decreased morbidity of this approach compared with open repair was readily apparent, as it avoided left thoracotomy, aortic cross-clamping, and left heart bypass. Repair of isolated descending thoracic aortic aneurysms using stent grafts was introduced in 1995, and in an anatomically suitable subgr...

The most common visceral artery aneurysm (VAA) is the splenic artery aneurysm (SAA), but other splanchnic vessels also may be affected by dilation.1,2 The dilation which does not affect all layers of the vessel wall is called pseudoaneurysm (PSAN). Blunt trauma of the upper abdomen and enzymatic injury to the vessel wall in pancreatitis are the most common causes of PSAN. Vessel rupture causes ...

Endovascular aneurysm repair (EVAR) was first published in 1991 by Parodi [1] and has since become a recognized standard method of treating infrarenal abdominal aortic aneurysms (AAA). The advantage of this minimally invasive treatment method is a reduced perioperative morbidity rate. EVAR is therefore the preferred treatment option particularly for older patients with an increased risk profile...

Aortic dissection occurs in about 5% of patients with coexistent abdominal aortic aneurysm (AAA); combined type B dissection complicated with visceral malperfusion and AAA is an uncommon aortic emergency and patients presenting with complications of thoracic aortic dissection have a dismal prognosis related to difficulties in treatment strategies. Despite tremendous improvement of endovascular ...

Open surgery is the elective treatment for mycotic aneurysms of the aorta. This surgery consists of resection of the aneurysm, debridement and revascularization with an in situ or extra-anatomic bypass. Even when surgery has been successful, the morbi-mortality is raised and the endovascular treatment has become an alternative for specific patients. When mycotic aneurysms involved the visceral ...

OBJECTIVES Patients with thoracic aneurysmal disease involving the arch and the descending or thoracoabdominal aorta may require more than one surgical intervention. The results of one-stage repair using a hybrid stent-graft in the frozen elephant trunk manner are presented. METHODS Between January 2005 and March 2012, 113 (age 67 ± 10 years) of 358 registered patients in the International E-...

OBJECTIVE To consider modifications in an experimental model of saccular aortic aneurysm, aiming at better reproducibility, to be used in the development of vascular prostheses. METHODS Experimental study in two phases, developed in the Center of Experimental Surgery and Bioterium (CCEB) of the University of Health Sciences of Alagoas (UNCISAL), with 11 hybrid swine, female, mean weight of 20...

We report on an asymptomatic 56-year-old male with incidental diagnosis of celiac trunk aneurysm, diagnosed during an ultrasound scan performed to control polycystic kidney disease. The CT scan revealed a 3.8 cm saccular aneurysm of the celiac artery dissected in the superior wall with a consequent 4.3 cm pseudoaneurysm; we adopted an endovascular approach to exclude the lesion by catheterizing...
