Randomized Controlled Trial Comparative Study
Impact of adding aspirin to beta-blocker and statin in high-risk patients undergoing major vascular surgery.
Beta-blockers (BB) and statins (S) independently have been shown to reduce perioperative mortality and myocardial infarction (MI) in patients undergoing vascular surgery. In this study we evaluated the benefits of adding aspirin (A) to BB and S (ABBS), with/without angiotensin-converting enzyme inhibitor (ACE-I) on postoperative outcome in high-risk patients undergoing major vascular surgery. ⋯ In high-risk patients undergoing major vascular surgery, ABBS therapy has superior 30-day and 12-month risk reduction benefits for MI, stroke, and mortality as compared with A, BB, or S independently. ACE-I did not demonstrate additional risk-reduction benefits.

Endovascular aneurysm repair (EVAR) is now the standard of care for elective infrarenal and ruptured abdominal aortic aneurysms (AAAs). Difficult proximal necks often require adjuvant measures to seal type 1 endoleaks. We believed this was a predictor of increased 30-day morbidity and mortality and reduced long-term survival. ⋯ During EVAR, deployment of a Palmaz stent is more frequently required in patients with rupture, female sex, and larger sac size. However, Palmaz stent deployment itself is not an independent predictor of increased 30-day mortality in either the elective or emergency setting or of poorer long-term survival. However, they are associated with a greater number of postoperative endoleaks, especially type 1 endoleaks, and predict a greater need for secondary interventions.

Port-a-Cath complicated by infection or migration not removed by manual traction: usefulness of cardiac pacing leads extraction techniques.
Long-term use of Port-a-Caths (PACs) is related to device-related delayed complications. The aim of this study is to describe the high success rate and safety of cardiac pacing lead extraction techniques used for PACs complicated by infection or migration and not removed by manual traction. ⋯ In experienced centers, cardiac pacing lead extraction techniques may be considered as an additional, efficacious, safe option for extraction of otherwise nonremovable entrapped PACs before surgery.

Comparative Study
Postoperative cardiac damage after standardized carotid endarterectomy procedures in low- and high-risk patients.
We conducted a comparison of postoperative cardiac damage, defined as cardiac troponin I (cTn-I) elevation, after carotid endarterectomy in low- and high-risk patients. ⋯ Carotid endarterectomy is followed by an increase in cTn-I value>0.5 ng/mL in 14% of all cases, although symptomatic cardiac ischemia is very low. However, high-risk patients as defined by the SAPPHIRE criteria do not show an increased risk of cardiac damage compared to low-risk patients. Larger studies using cTn-I as a marker of postoperative cardiac damage, after carotid endarterectomy or stenting, are needed.
