The Petticoat concept for endovascular treatment of Type B aortic dissection
No full textINTRODU CTIO N: A systematic literature search on outcomes of the PETTICOA T technique was aimed at verifying the feasibility and safety of the procedure, comparing clinical outcomes with standard stent-grafting of the proximal entry tear as well as describing the possible benefits in terms of aortic remodeling. EVIDE NCE ACQUISI TIO N: Potentially eligible papers were sought through a computerized search of MEDLI NE and SCOPUS databases between January 2006 and June 2016. Key words used for potentially eligible studies were: "dissection," "bare stent," "thoracic," "endovascular," "PETTICOA T". Studies were considered for review on the basis of these criteria: including more than 5 cases, providing full information on the type of dissection treated and the onset of dissection as well as reporting clinical and technical outcomes. EVIDENCE SYNTHESIS: The literature search identified 11 studies (4 prospective and one controlled) in which the PETTICOAT treatment was employed (439 cases) in type A (N.=40; 9.1%) and Type B (N.=399; 90.9%) dissection complicated by malperfusion in 48.4% of cases with different dissection onsets: acute in 295 cases (67.3%), subacute in 54 cases (12.3%) and chronic in 90 cases (20.5%). Due to the heterogeneity of the cohorts, only the perioperative results of 4 papers (143 patients) reporting a single stage PETTICOA T procedure for the treatment of acute (89 cases) or subacute (54 cases) type B dissection were pooled together. The pooled data demonstrated that the procedure is feasible and safe with an overall 30-day mortality rate of 4.9% and clinical success rate of 90.2%. Six out of 11 papers proposed a clinical comparison between TEVAR alone (TEVAR ) and PETTICOA T in the same dissection setting with no clinical success differences reported at short-term. In terms of aortic remodeling 9 out of 11 papers reported the behavior of lumina after the procedure. All studies observed an early significant expansion of the true lumen expansion in the thoracic and abdominal aorta but when false lumen is taken into consideration, the data are more heterogeneous: both the thoracic and abdominal false lumen decreased in size significantly postoperatively due to the redistribution of the lumens but, at follow-up (6 studies), the FL continued to decrease in size in the stent-grafted area, while in the abdominal aorta remained stable with no shrinkage (4 studies) or increased (2 studies at 2 year follow-up). CONCLUSIO NS: Analysis of the literature data, not only does it demonstrate that the PETTICOA T technique is safe and feasible but also that it is able to enhance the effect of the proximal TEVAR improving the re-expansion of the true lumen of the distal thoraco-abdominal aorta possibly improving end-organ perfusion. However, since there is no evidence of improved short and mid-term survival as well as positive remodeling of the false lumen in the distal aorta, when compared to a simple proximal stent-grafting, a wide-spread use of the PETTICOA T technique is not justified and it should be limited to cases complicated by dynamic malperfusion as a bailout adjunctive tool
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
New technical approach for type B dissection: from the PETTICOAT to the STABILISE concept
No full textEndovascular treatment of acute complicated type B aortic dissection (TBD) has recently acquired a primary therapeutic role when anatomically feasible. However, strategies meant to simply close the proximal entry tear leave the risk of persistent perfusion of the false lumen(FL) through additional tears in the thoracoabdominal aorta, and therefore the potential for aneurysmal degeneration remains significant over the years. Thus, additional bare stent implantation in the thoracoabdominal aorta has been proposed to promote true lumen (TL)expansion, malperfusion relief, and intimal lamella stabilization. This technique, also known as the Provisional Extension To Induce Complete Attachment Technique (PETTICOAT) offers good short- and mid-term results, but some degree of perfusion of the FL is still maintained, and the aorta showed a tendency to grow distally to the stent-graft. An evolution of PETTICOAT, mainly including aggressive ballooning of the covered stent-graft and of the distal bare stents deployed in the TL, in order to obtain full expansion of the stents in a single channeled aorta, has been proposed in 2012 and named Stent-Assisted Balloon-Induced Intimal Disruption and Relamination in Aortic Dissection Repair (STABILISE) technique. Although this approach produced excellent early results in single-center series, it did not gain immediate acceptance in the community, mainly because of concerns regarding the potential risk of rupturing the aorta during ballooning. In this review, we summarize the current evidence on the results of these strategies, we present a recently modified approach of the STABILISE technique, and report the early results in a cohort of patients treated in the last two years at our institution
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
