Performed without pulmonary arterial catheterization, iodinated contrast media, or ionizing radiation, pulmonary MR angiography had a high accuracy for depicting lobar and segmental emboli, but was unable to depict four of five subsegmental emboli.
Disease recurrence after OLT does occur, but overall, it is relatively uncommon. Recurrence rates vary significantly and depend, in part, on indication for OLT. With medium-term follow up, recurrent disease does not have an effect on mortality.
A total of 50% of patients with end-to-end biliary anastomosis had biliary tract complications. Biliary strictures presented later than leaks, and the majority of these complications were managed without the need for surgery.
A pilot randomized controlled trial that evaluated the effect of remote ischemic preconditioning (RIPC) on clinical outcomes following major vascular surgery was performed. Eligible patients were those scheduled to undergo open abdominal aortic aneurysm repair, endovascular aortic aneurysm repair, carotid endarterectomy, and lower limb revascularization procedures. Patients were randomized to RIPC or to control groups. The primary outcome was a composite clinical end point comprising any of cardiovascular death, myocardial infarction, new-onset arrhythmia, cardiac arrest, congestive cardiac failure, cerebrovascular accident, renal failure requiring renal replacement therapy, mesenteric ischemia, and urgent cardiac revascularization. Secondary outcomes were components of the primary outcome and myocardial injury as assessed by serum troponin values. The primary outcome occurred in 19 (19.2%) of 99 controls and 14 (14.1%) of 99 RIPC group patients (P = .446). There were no significant differences in secondary outcomes. Our trial generated data that will guide future trials. Further trials are urgently needed.
Even though up to 60% of premature infants less than 28 weeks gestation develop persistent patent ductus arteriosus (PDA), there remains controversy regarding if, when, and how to close the PDA. Failure to close the PDA has been associated with significant morbidity but no cause‐and‐effect has been proven for short‐term or long‐term outcomes in modern times. Surgical closure has the advantage of eliminating the PDA, but short‐term complications and long‐term adverse outcomes are worrisome. Intravenous indomethacin has been the “gold standard” for pharmacologic treatment over the past 40 years with high closure rates and decreased incidence of severe intraventricular hemorrhage (IVH) and pulmonary hemorrhage with early treatment but without improvement in long‐term outcomes and with risk of renal toxicity. Intravenous ibuprofen has less vasoconstrictive toxicity than indomethacin with comparable closure rates but without improvement in IVH and with hyperbilirubinemia risks. Earlier this decade, acetaminophen (paracetamol) was discovered to effectively close the PDA with good short‐term safety profile. Although promising, acetaminophen treatment requires further studies regarding long‐term safety as well as ideal dosing and route of administration.
Following the establishment of an IVC filter database and interventional radiology led follow-up, we demonstrate a significant improvement in the attempted retrieval rates of IVC filters and the number of patient's lost to follow-up.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
