Bicuspid aortic valve (BAV), the most common congenital heart defect, is associated with progressive aortic dilation and increased risk of dissection and rupture. The use of an angiotensin-converting enzyme (ACE) inhibitor has recently proven effective in slowing the rate of aortic dilation in other aortopathies, suggesting it may also be ...

In the endovascular treatment of wide-necked unruptured aneurysms, there is controversy over which adjunctive device (stent vs. balloon) is appropriate. At the payer level it has been posited that stents and balloons treat the same aneurysms, and as such the more expensive stents should not be reimbursed. We challenge this ...

Intraoperative angiography in cerebrovascular neurosurgery can drive the repositioning or addition of aneurysm clips. Our institution has switched from a strategy of intraoperative digital subtraction angiography (DSA) universally, to a strategy of indocyanine green (ICG) videoangiography with DSA on an as-needed basis. We retrospectively evaluated whether the rates of perioperative ...

A native arteriovenous fistula (AVF) should be systematically evaluated at 4 to 6 weeks after creation. Any clinical indications of nonmaturation should be promptly followed up and confirmed by detailed duplex ultrasonography looking for a deep vein or inadequate access flow due to stenoses. Once vein depth has been ruled ...

The increasing manufacture and use of products based on nanotechnology raises concerns for both workers and consumers. Various studies report induction of pulmonary inflammation after inhalation exposure to nanoparticles, which can vary in aspects such as size, shape, charge, crystallinity, chemical composition, and dissolution rate. Each of these aspects can ...

Forearm arteriovenous fistula (AVF) is a direct anastomosis between the radial artery and the cephalic vein or the ulnar artery and the basilic vein, which are small-caliber vessels. The surgical technique must be precise to avoid postoperative stenosis of the anastomosis which may result in early thrombosis or nonmaturation. In ...

Infectious aortitis is a rare disease with an unfavorable prognosis, though prompt and adequate treatment can reduce its high mortality rate. Pseudoaneurysms caused by aortitis tend to rupture when treatment is delayed. For this reason, determining the appropriate timing of surgical repair is critical. To date, there are no data ...

Hypertensive retinal microvascular abnormalities include an increased retinal vein-to-artery diameter ratio. Because central retinal vein pressure depends on cerebrospinal fluid pressure (CSFP), we examined whether the retinal vein-to-artery diameter ratio and other retinal hypertensive signs are associated with CSFP. Participants of the population-based Beijing Eye Study (n = 1,574 subjects) ...

Gaseous microemboli (GME) define small bubbles as < 200 microm in size. GME are reported to increase morbidity after cardiopulmonary bypass (CPB) and cardiac surgery. To prevent intrusion of GME into the systemic circulation during CPB, arterial line filtration is generally recommended. New trends in oxygenator design promote location of ...

The autogenous brachiocephalic fistula is a recognized secondary access for hemodialysis. However, veins in the antecubital fossa are often damaged, due to repeated venipunctures and subsequent scarring. Sometimes their anatomy does not enable successful arteriovenous fistula creation. In cases when the proximal part of the cephalic vein seemed patent, during ...

Penetrating aortic trauma is associated with high mortality rates. We report the case of a 24-year old male who presented with a self-inflicted abdominal aortic penetration injury, resulting in a pseudoaneurysm. Rather uniquely, he was managed through prophylactic stenting to his abdominal aorta; this case was also rare in that ...

Type II endoleak is a common phenomenon after endovascular aortic aneurysm repair (EVAR). The majority of type II endoleaks are considered benign, since approximately one third of them resolve spontaneously and they have no influence on mortality and rupture rate after EVAR. Thus, type II endoleak without sac expansion is ...

Stent graft migration influences the long-term durability of endovascular aortic repair. Flow-induced displacement forces acting on the attachment zones may contribute to migration. Proximal fixation of aortic stent grafts has been improved by using hooks, while distal fixation and stent graft interconnections depend on self-expansion forces only. We hypothesized that ...
