Incidence of vascular injuries following the use of the Angio-Seal closure device following endovascular procedures in a single Center
No full textINTRODUCTION: Percutaneous closure devices have been used to obtain rapid hemostasis and early mobilization of the patient after arterial catheterization. However, we observed challenging problems with the sealing procedure that require further surgical intervention. The present report is a retrospective analysis of the patterns of injury and the final outcome of four cases of femoral artery injury following the use of Angio-Seal.
METHODS: During the last 24 months, in a group of 175 patients (131 men, 44 women; median age 68.4 years, range 47-81 years) underwent percutaneous closure after diagnostic (n = 53) or therapeutic (n = 122) endovascular procedures. Among them we observed four patients (three men, one woman; median age 65.2 +/- 10.8 years, range 47-75 years) who developed severe limiting claudication and required vascular repair of an iatrogenic vascular injury following deployment of the Angio-Seal. They had a femoral thrombosis due to narrowing/severe intimal dissection.
RESULTS: All patients required operative intervention with removal of the device. We performed femoropopliteal thrombectomy and common femoral endarterectomy with patch angioplasty (n = 2), resection of the femoral bifurcation and reimplantation of the deep femoral artery (n = 1), and femoral bifurcation endarterectomy with direct arterial suture (n = 1). The median hospital stay was 6.5 +/- 3.8 days (range 4-12 days). Limb salvage was achieved in all of the surviving patients at a mean follow-up of 7 months (range 1-12 months).
CONCLUSIONS: Vascular injuries are uncommon after use of the hemostasis closure device. When they occur, however, they are likely to require challenging surgical correction
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
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
Disostruzione cavale per leiomiomatosi
No full textIntravenous leiomyomatosis is a rare benign vascular tumour which originates from the smooth muscle cells, growing and spreading into the pelvic veins of female patients. Frequently, intravenous leiomyomatosis is misdiagnosed and treated without appropriate preoperative imaging. The correct therapy consists of complete excision of the tumour. We report a patient who was treated using ileocaval disobstruction with pelvic leiomyoma ablation, having previously undergone excision of a right atrial neoplasia with tricuspidal valvuloplasty. No evidence of recurrence and patency of the treated vessels have been reported after an 18-month follow-up
