Prevention of rupture of abdominal aortic aneurysm

Two thirds of patients with an abdominal aortic aneurysm (AAA) have relevant coronary artery disease (CAD). AAAs are prevalent in up to 16% of smokers with CAD. General screening of AAA is controversial. Aim was to assess the potential of finding AAA prior to rupture among patients with known CAD. Main endpoint was whether AAA could have been found during follow-up by sonography or at other time of cardiovascular evaluation.

Genome-wide association study of intracranial aneurysm identifies three new risk loci

Saccular intracranial aneurysms are balloon-like dilations of the intracranial arterial wall; their hemorrhage commonly results in severe neurologic impairment and death. We report a second genome-wide association study with discovery and replication cohorts from Europe and Japan comprising 5,891 cases and 14,181 controls with approximately 832,000 genotyped and imputed SNPs across discovery cohorts. We identified three new loci showing strong evidence for association with intracranial aneurysms in the combined dataset, including intervals near RBBP8 on 18q11.2 (odds ratio (OR) = 1.22, P = 1.1 x 10(-12)), STARD13-KL on 13q13.1 (OR = 1.20, P = 2.5 x 10(-9)) and a gene-rich region on 10q24.32 (OR = 1.29, P = 1.2 x 10(-9)). We also confirmed prior associations near SOX17 (8q11.23-q12.1; OR = 1.28, P = 1.3 x 10(-12)) and CDKN2A-CDKN2B (9p21.3; OR = 1.31, P = 1.5 x 10(-22)). It is noteworthy that several putative risk genes play a role in cell-cycle progression, potentially affecting the proliferation and senescence of progenitor-cell populations that are responsible for vascular formation and repair.

Giant aneurysm after aortic coarctation: repair without circulatory arrest

We describe the case of a 23-year-old patient presenting for redo aortic arch surgery because of recoarctation and poststenotic aneurysm formation after patch aortoplasty in infancy. Using the hemi-clamshell approach, the entire aortic arch was replaced and the supraaortic branches were reimplanted. The applied surgical technique using hypothermic extracorporeal circulation without cardiac arrest allowed an uninterrupted cerebral and spinal cord perfusion due to stepwise clamping of the aortic arch during reconstruction and resulted in an excellent neurologic outcome at six-month follow-up.?

Patient preference for surgical method of abdominal aortic aneurysm repair: postal survey

To determine whether men with small abdominal aortic aneurysm have a preference between either endovascular or open aneurysm repair for future treatment.

Repair of ruptured abdominal aortic aneurysm in octogenarians

To determine whether advanced age was independently associated with prohibitive surgical risks or impaired long-term prognosis after ruptured aortic aneurysm repair.

The influence of thrombus, calcification, angulation, and tortuosity of attachment sites on the time to the first graft-related complication after endovascular aneurysm repair

Endovascular aneurysm repair (EVAR) is associated with high graft-related complication rates during follow-up. Anatomical fit between patient and endograft could be an important factor for successful treatment. Aim was to assess whether extent of thrombus, calcification, angulation, and tortuosity are associated with occurrence of complications after EVAR.

Endovascular suitability and outcome after open surgery for ruptured abdominal aortic aneurysm

Endovascular repair of ruptured abdominal aortic aneurysm (rAAA) has rapidly gained popularity, but superior results may be biased by patient selection. The aim was to investigate whether suitability for endovascular repair predicted survival, irrespective of technique of repair.

Do statins reduce the risk of aneurysm development? A case-control study

Recent studies in rats have demonstrated that statins may have an inhibitory effect on intracranial aneurysm (IA) development. The purpose of this study was to assess whether long-term statin use is associated with a reduced risk of IA formation in humans.
