Coil embolization as an alternative endovascular approach for ruptured superficial femoral artery aneurysms
No full textPurpose: True aneurysms of the superficial femoral artery (SFAA) are rare and, the endovascular approach using covered stents has gained more popularity. We report an endovascular alternative using embolization coils for treatment of a ruptured SFAA.
Case description: An 88-old male admitted for a ruptured true SFAA (67×52mm in diameter and 70mm in length) presenting with painful mass pulsating in the proximal third of the left thigh. His surgical history consisted of an infrarenal abdominal aneurysm treated by open surgery and an ipsilateral popliteal aneurysm treated with prosthetic bypass by a medial approach; this was revealed to be occluded at the CT scan evaluation. The patient was asymptomatic for limb ischaemia, therefore we decided to perform embolization of the SFA with coils (MReye®Embolization Coil, Cook Medical, Bloomington,USA). Under local anaesthesia, via a 5-Fr sheath and an antegrade approach, coils were deployed first at the distal neck of the SFAA and then to its proximal neck. On the angiogram, complete aneurysm sac thrombosis with no leaks was achieved. At 6-month follow-up, the SFAA remained occluded, and the patient had not developed any sign of limb ischaemia.
Conclusion: Coil embolization of SFAA in selected cases represents a feasible and safe endovascular alternative
The effectiveness of the prevention measures on stroke incidence in patients with ipsilateral carotid disease
No full textBackground: The aim of this study is to assess the possible causes of cerebral ischemic events for ipsilateral carotid stenosis in the era of the best medical therapy. Methods: This is a retrospective and observational study conducted on patients entered into stroke protocol and subsequently underwent carotid endarterectomy (CEA) for ipsilateral stenosis at the University-Hospital of Ferrara. A 4-year period of time (January 2014 to December 2017) was investigated and demographic data, comorbidities, current medical therapies and instrumental examinations performed prior hospitalization were collected. Results: We identified 78 patients who underwent CEA for symptomatic carotid stenosis. The mean age was 62 (range 52 to 76), 64.1% were male. Among those, 20% presented with acute internal carotid occlusion, 60% had a stenosis >90%, 14% between 70-90%, 6% of 60-69% and 32% had a contralateral stenosis >60%. Moreover, 82.4% of them were not aware of having carotid stenosis since they had never been assessed with duplex ultrasound. Among these patients 49% were not under antiplatelet/anticoagulant medication, 46 patients had systemic hypertension but untreated in 74.5% of them, 31 patients had dyslipidemia without taking statin-therapy in 66.7% of cases, 35 patients had hyperglycemia but untreated in 70% as confirmed measuring glycated hemoglobin and 52.9% were smokers. Among patients who were aware of having hemodynamic carotid stenosis, 33% of them was documented a scarce adherence to the medical therapy and 22% was not set up an adequate one. Conclusions: The non-diagnosed carotid stenosis and insufficient medical treatment due to uninvestigated cardiovascular diseases revealed to be frequent in patients with symptomatic carotid stenosis. This suggests that more should be done to enrich the screening strategies in order to offer better prevention from cardiovascular events
Exercise-based functional recovery from severe upper extremity arterial disease due to bilateral subclavian artery obstruction in a person with giant cell arteritis
No full textWe report the case of a 71-year-old woman diagnosed with giant cell arteritis with bilateral subclavian and axillary obstruction and severe arm claudication that occurred 3 months earlier and was non-regressed after corticosteroids. Before possible revascularization, the patient was initiated to a personalized home-based graded exercise program including walking, hand-bike pedaling, and muscle strength training. During the 9 months of treatment, the patient progressively improved radial pressure values (10 to 85 mmHg), hand temperature values by infrared-thermography (+2.1 °C), arm endurance, and forearm muscle oxygenation by near-infrared spectroscopy. Home-based graded exercise proved to be a noninvasive option for upper limb claudication
Open repair with resection and reimplantation for popliteal artery aneurysm
No full textPopliteal artery aneurysms are the most frequent type of peripheral arterial aneurysm and can be repaired by either open or endovascular techniques. An 81-year-old man presented with leg swelling and during duplex ultrasound examination was diagnosed a popliteal aneurysm. The transverse diameter was 3.6 × 4.5cm, length 2.8cm, one run-off vessel patent. The popliteal aneurysm was asymptomatic for clinical signs of limb ischaemia. We opted for an open surgical repair through a posterior approach. During dissection of the popliteal artery above and below the aneurysm, the two non-diseased popliteal extremities appeared to be very close, leading to the decision to perform an end-to-end anastomosis between the two arterial extremities. The patient was discharged after three days with no adverse events. Follow-up consisted of duplex ultrasound examination at one, three and six months, and then annually. At the six-month follow-up there was no restenosis at the anastomosis

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
