Hybrid one-stage approach to extensive atherosclerotic aneurysm of thoracoabdominal aorta.

We report a 62-year-old man with an atherosclerotic Crawford type II aneurysm involving both common iliac arteries who underwent surgical revascularization of the visceral vessels and renal arteries from the ascending aorta and subsequent endovascular aneurysmal exclusion. Computed tomography imaging at 2 years showed complete exclusion of the aneurysm throughout the thoracoabdominal aorta, confirming the successful antegrade revascularization of visceral vessels and renal arteries. A hybrid approach to thoracoabdominal aneurysms using antegrade visceral and renal revascularization from the ascending aorta before endovascular repair is technically feasible and might constitute an attractive alternative to conventional surgical treatment.

Hybrid treatment of thoracoabdominal aortic aneurysms with the use of a new prosthesis

We report the case of a 72-year-old woman with thoracoabdominal aortic aneurysm who underwent hybrid surgical and endovascular procedure. First, debranching of the aortic arch and implantation of a new multi-branched prosthesis with transdiaphragmatic celiac artery and superior mesenteric artery revascularization was performed. Two weeks later the procedure was successfully completed with aneurysmal exclusion by deployment of multiple stent grafts. The postoperative course was uneventful. A two-staged surgical and endovascular approach with the use of a new prosthesis reduces the risk of endoluminal graft endoleak and may constitute an attractive alternative to conventional surgery in management of high-risk thoracoabdominal aortic aneurysms

Whole body perfusion in patients undergoing frozen elephant trunk for type A acute aortic dissections

8noneThe Frozen Elephant Trunk (FET) can be adopted in selected type A acute aortic dissections (TAAAD). During FET, a prolonged distal circulatory arrest exposes the spine and visceral organs to potential ischemic injuries. Antegrade distal aortic perfusion (ADAP) could minimize this risk: we describe the technical aspects of the simultaneous use of antegrade cerebral perfusion (ACP) and ADAP achieving a "Whole Body Perfusion" (WBP) during FET.Cappabianca, Giangiuseppe; Roscitano, Claudio; Bichi, Samuele; Cricco, Antonio; Parrinello, Matteo; Beghi, Cesare; Albano, Giovanni; Esposito, GiampieroCappabianca, Giangiuseppe; Roscitano, Claudio; Bichi, Samuele; Cricco, Antonio; Parrinello, Matteo; Beghi, Cesare; Albano, Giovanni; Esposito, Giampier

Hybrid three-stage repair of mega-aortic syndrome with the Lupiae technique: 10-year results

9nononeBackground: Mega-aortic syndrome (MAS) is a rare disease carrying a poor prognosis if treated conservatively. Open repairs of these aneurysms are invasive, while totally endovascular repairs are associated with higher rates of late reintervention due to endoleaks, compromising long-term prognosis. We describe the 10-year results of a hybrid three-stage approach to MAS using the Lupiae technique. Methods: Between 2006 and 2016, 27 patients with MAS extending from the ascending aorta to the iliac arteries (MAS type III) underwent: (I) a surgical aortic arch debranching, using the Vascutek Lupiae™ multibranched graft to create a proximal Dacron landing zone; (II) an abdominal aorta debranching to create a distal Dacron landing zone and (III) the implantation of multiple endovascular stents to exclude any residual aneurysm between the two landing zones. Results: One patient died following the first stage, and another following the second stage of the repair (overall mortality 7.4%). The interval between the first and the second stage was 58.3±16.1 days. The interval between the second and the third stage was 47.7±13.1 days. Four-year survival was 88.6%±6.2% while 10-year survival was 51.7%±17.9%. One patient had a type III endoleak after the third stage that self-resolved within 6 months without intervention. No patient had type I or II endoleaks and none underwent redo procedures. Mean follow-up was 5.9±3.6 years and completeness was 100%. Conclusions: Three-stage hybrid repairs using the Lupiae technique can be safely performed in MAS type III patients. Short intervals between the stages should mitigate the risk of rupture during the waiting periods and may enhance patient compliance, but to achieve this, the burden and the complexity of the first stage must be carefully weighted. Our strategy improves the long-term survival of these patients compared to their natural history and is less invasive than an open repair. The adoption of Dacron landing zones appears to be associated with very low rates of reintervention due to endoleaks.noneEsposito, Giampiero*; Cappabianca, Giangiuseppe; Beghi, Cesare; Cricco, Antonio M.; Memmola, Cataldo; Bichi, Samuele; Miccoli, Matteo; Conte, Massimiliano; Contegiacomo, GaetanoEsposito, Giampiero; Cappabianca, Giangiuseppe; Beghi, Cesare; Cricco, Antonio M.; Memmola, Cataldo; Bichi, Samuele; Miccoli, Matteo; Conte, Massimiliano; Contegiacomo, Gaetan

Hybrid aortic arch debranching with staged endovascular completion in DeBakey type I aortic dissection

Background We assess midterm results of a hybrid approach to DeBakey type I aortic dissection using a new multibranched Dacron graft to create, by relocation of the inflow openings to the arch vessels toward the aortic root, a new aortic arch for an easier and safer second-staged endovascular stent grafting of the distal thoracic aorta. Methods From March 2006 to July 2008 24 patients with DeBakey type I aortic dissection underwent ascending aorta and aortic arch replacement with debranching of epiaortic vessels using a new prosthesis to create an optimal landing zone for possible subsequent endovascular stent grafting of the distal thoracic aorta. Fifteen patients, who postoperatively presented a residual patent distal false lumen, underwent a successful second-stage endovascular stent-graft implantation. Results One patient died after the surgical stage while there was no death after the endovascular stage with hospital mortality of 4.2%. Follow-up confirmed complete thrombosis of the residual distal false lumen in 95.6% and partial thrombosis in 4.4% of patients with no evidence of endoleaks in the cases that required the endovascular procedure. Overall actuarial survival at 28 months is 92.1% ± 7.9% with 100% freedom from reoperation. Conclusions Hybrid treatment of DeBakey type I aortic dissection with aortic arch debranching, using a new multibranched prosthesis (Lupiae Graft; Vascutek Terumo Inc, Scotland, United Kingdom) is confirmed to facilitate the subsequent endovascular completion. Midterm results in terms of survival and distal false lumen thrombosis are satisfactory. Further study of this operation is warranted to confirm the effectiveness and the durability of this approach. © 2010 The Society of Thoracic Surgeons

Biosynthesis of heme O in intraerythrocytic stages of Plasmodium falciparum and potential inhibitors of this pathway

A number of antimalarial drugs interfere with the electron transport chain and heme-related reactions; however, the biosynthesis of heme derivatives in Plasmodium parasites has not been fully elucidated. Here, we characterized the steps that lead to the farnesylation of heme. After the identification of a gene encoding heme O synthase, we identified heme O synthesis in blood stage parasites through the incorporation of radioactive precursors. The presence of heme O synthesis in intraerythrocytic stages of Plasmodium falciparum was confirmed by mass spectrometry. Inabenfide and uniconazole–P appeared to interfere in heme synthesis, accordingly, parasite growth was also affected by the addition of these drugs. We conclude that heme O synthesis occurs in blood stage-P. falciparum and this pathway could be a potential target for antimalarial drugs.Fil: Simão Gurge, Raquel M..

Multimorbidity and polypharmacy in the elderly: Lessons from REPOSI

The dramatic demographic changes that are occurring in the third millennium are modifying the mission of generalist professionals such as primary care physicians and internists. Multiple chronic diseases and the related prescription of multiple medications are becoming typical problems and present many challenges. Unfortunately, the available evidence regarding the efficacy of medications has been generated by clinical trials involving patients completely different from those currently admitted to internal medicine: much younger, affected by a single disease and managed in a highly controlled research environment. Because only registries can provide information on drug effectiveness in real-life conditions, REPOSI started in 2008 with the goal of acquiring data on elderly people acutely admitted to medical or geriatric hospital wards in Italy. The main goals of the registry were to evaluate drug prescription appropriateness, the relationship between multimorbidity/polypharmacy and such cogent outcomes as hospital mortality and re-hospitalization, and the identification of disease clusters that most often concomitantly occur in the elderly. The findings of 3-yearly REPOSI runs (2008, 2010, 2012) suggest the following pertinent tasks for the internist in order to optimally handle their elderly patients: the management of multiple medications, the need to become acquainted with geriatric multidimensional tools, the promotion and implementation of a multidisciplinary team approach to patient health and care and the corresponding involvement of patients and their relatives and caregivers. There is also a need for more research, tailored to the peculiar features of the multimorbid elderly patient

Antipsychotic prescription and mortality in hospitalized older persons

Background: Recent scientific reports have shown that older persons treated with antipsychotics for dementia-related behavioural symptoms have increased mortality. However, the impact of these drugs prescribed during hospitalization has rarely been assessed. We aimed to investigate whether antipsychotics are associated with an increased risk of mortality during hospitalization and at 3-month follow-up in elderly inpatients. Methods: We analyzed data gathered during two waves (2010 and 2012) by the REPOSI (Registro Politerapie Società Italiana Medicina Interna). All new prescriptions of antipsychotic drugs during hospitalization, whether maintained or discontinued at discharge, were collected, and logistic regression models were used to analyze their association with in-hospital and 3-month mortality. Covariates were age, sex, the Short Blessed Test (SBT) score, and the Cumulative Illness Rating Scale. Results: Among 2703 patients included in the study, 135 (5%) received new prescriptions for antipsychotic drugs. The most frequently prescribed antipsychotic during hospitalization and eventually maintained at discharge was haloperidol (38% and 36% of cases, respectively). Patients newly prescribed with antipsychotics were older and had a higher Cumulative Illness Rating Scale comorbidity index both at admission and at discharge compared to those who did not receive a prescription. Of those prescribed antipsychotics, 71% had an SBT score ≥10 (indicative of dementia), 12% had an SBT score of 5–9 (indicative of questionable dementia); and 17% had an SBT score <5 (indicative of normal cognition). In-hospital mortality was slightly higher in patients prescribed antipsychotic drugs (14.3% vs 9.4%; P = 0.109), but in multivariate analysis only male sex, older age, and higher SBT scores were significantly related to mortality during hospitalization. At 3-month follow-up, only male sex, older age, and higher SBT scores were associated with mortality. Conclusion: We found that the prescription of antipsychotic drugs during hospitalization was not associated with in-hospital or follow-up mortality. Short-term antipsychotic prescriptions (for acutely ill patients) may have a different effect than long-term, repeated prescriptions
