Shockwave intravascular lithoplasty for the treatment of calcified carotid artery stenosis: A very early single-center experience

2020

Endovascular treatment of calcified carotid disease represents one of the main challenges for the interventionalists. Plaque calcium load is one of the most important factors affecting the risk of procedural complications. A new tool called Shockwave intravascular lithotripsy (S-IVL; Shockwave Medical, Inc.) has been recently approved for the treatment of heavily calcified coronary and lower limb arteries but minimal data exist about the treatment of carotid arteries. We report our early experience of carotid stenting using S-IVL. We report two cases of symptomatic patients with severely calcified carotid artery diseases who were turned down for vascular surgeries. The first case was succes…

Analysis and evaluation of periodic physiological organ motion in radiotherapy treatments.

2003

Background and purpose: A system for the detection, measurement and analysis of the periodic physiological organ motion during radiotherapy treatment is proposed and clinically tested in this paper. Material and methods: The procedure is based on the acquisition of fluoroscopic sequences, followed by an automatic detection of the movement using cross-correlations with matched filters. Results: The system generates a probability density function (PDF) of finding a mobile organ in a position at a certain time. The maximum path of the mobile structures can be determined to define the planning target volume (PTV) without ambiguities. Conclusions: Physiological movements can be accurately includ…

Multicenter and all-comers validation of a score to select patients for manual thrombectomy, the DDTA score.

2021

Background Routine manual thrombectomy (MT) is not recommended in primary percutaneous coronary intervention (P-PCI) but it is performed in many procedures. The objective of our study was validating the DDTA score, designed for selecting patients who benefit most from MT. Methods Observational and multicenter study of all consecutive patients undergoing P-PCI in five institutions. Results were compared with the design cohort and the performance of the DDTA was analyzed in all patients. Primary end-point of the analyses was TIMI 3 after MT; secondary endpoints were final TIMI 3, no-reflow incidence, in-hospital mortality and in-hospital major cardiovascular events (MACE). In-hospital prognos…

Alterations in 18F-FDG accumulation into neck-related muscles after neck dissection for patients with oral cancers

2015

Background: 18 F-fluoro-2-deoxy-D-glucose ( 18 F-FDG) accumulations are commonly seen in the neck-related muscles of the surgical and non-surgical sides after surgery with neck dissection (ND) for oral cancers, which leads to radiologists having difficulty in diagnosing the lesions. To examine the alterations in 18 F-FDG accumulation in neck-related muscles of patients after ND for oral cancer. Material and Methods: 18 F-FDG accumulations on positron emission tomography (PET)-computed tomography (CT) in neck-related muscles were retrospectively analyzed after surgical dissection of cervical lymph nodes in oral cancers. Results: According to the extent of ND of cervical lymph nodes, the rate…

Anthracyclines and regional myocardial damage in breast cancer patients. A multicentre study from the Working Group on Drug Cardiotoxicity and Cardio…

2021

Abstract Aims In breast cancer (BC) patients treated with anthracyclines-based therapies, we aim at assessing whether adjuvant drugs impact cardiac function differently and whether their cardiotoxicity has a regional pattern. Methods and results In a multicentre study, 146 BC patients (56 ± 11 years) were prospectively enrolled and divided into three groups according to the received treatments: AC/EC-Group (doxorubicin or epirubicin + cyclophosphamide), AC/EC/Tax-Group (AC/EC + taxanes), FEC/Tax-Group (fluorouracil + EC + taxanes). Fifty-six patients of the total cohort also received trastuzumab. Left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS) were calculated …

Anatomical basis for the interposition of a gastric pouch between the ileum and the anus after total proctocolectomy.

2003

After a total proctocolectomy, ileoanal continuity is achieved by an ileal pouch–anal anastomosis. This anastomosis is not possible when the ileum cannot reach the anus. To avoid definitive ileostomy in this circumstance, we devised a gastric pouch, taken from the left half of the vertical portion of the stomach, vascularized by the right gastroepiploic pedicle, then interposed it between the ileum and the anus. The aim of this anatomical study on seven cadavers was to estimate the capacity of this gastric pouch to reach the anus. The distance between the caudal edge of the pubic symphysis and the apex of the pouch was measured. It is accepted that an ileal pouch always reaches the anus wit…

Transcatheter embolization of the kidney with butyl-2-cyanoacrylate: Experimental and clinical results

1978

The technique and efficacy of therapeutic catheter embolization of the kidney with butyl-2-cyanoacrylate (Histoacryl) were studied in 80 rabbits (including control groups) and in 10 dogs. A mixture of butyl-2-cyanoacrylate, 50% glucose, and tantalum powder was used for the embolization. Complete and permanent vascular occlusion was found in nearly all cases. The main complication observed was a reflux of embolizing material into the lumbar arteries, which occurred in seven rabbits. Clinically, therapeutic embolization was performed in six patients with hypernephroma. The indication for embolization in these patients, as well as in two others with iatrogenic lesions, was pronounced hematuria…

An International, Multicenter Retrospective Observational Study to Assess Technical Success and Clinical Outcomes of Patients Treated with an Endovas…

2022

Introduction: Type III endoleaks post-endovascular aortic aneurysm repair (EVAR) warrant treatment because they increase pressure within the aneurysm sac leading to increased rupture risk. The treatment may be difficult with regular endovascular devices. Endovascular aneurysm sealing (EVAS) might provide a treatment option for type III endoleaks, especially if located near the flow divider. This study aims to analyze clinical outcomes of EVAS for type III endoleaks after EVAR. Methods: This is an international, retrospective, observational cohort study including data from 8 European institutions. Results: A total of 20 patients were identified of which 80% had a type IIIb endoleak and the r…
