Filter by:BACKGROUND - Major blood loss is frequent in open repair of ruptured and intact abdominal aortic aneurysm (AAA) as well as in aorto-bifurcated prosthesis insertion due to aortoiliac occlusive disease. - Major blood loss is associated with death, post-operative complications and coagulopathy. - Data from randomized trials in trauma patients indicate that a high plasma to red blood cell (RBC) transfusion ratio reduces 30-day mortality. - No randomized trial data are available for the AAA population. - Observational data demonstrate, that a high plasma:RBC transfusion ratio associates to a lower 30 day mortality. However, the reports are based on small cohorts of 78-165 patients, short term outcomes and lack information on major adverse events such as cardiac and respiratory. - The Danish Vascular Registry (DVR), covering 1996-2018, contains data on approx. 4,400 ruptured and 8,200 intact (elective/symptomatic) AAA repairs, and 5,400 open aortoiliac repairs due to occlusive disease. Expected total count 1997-2018: 17,000. - The Danish Transfusion Database (DTDB), covering approx. 1997-2018, contains information on units of RBCs, plasma and platelets transfused. A unique patient identification number (CPR) allows merging of all data set. OBJECTIVE To identify whether resuscitation with a high plasma to RBC ratio associates to improves survival in open abdominal aortic surgery as compared to a low plasma to RBC-ratio. PICO - Population: Open abdominal aortic surgery - Intervention: "High FFP": FFP to RBC unit ratio of 2:3 to 3:3 (0.7 - 1.0) - Comparison: "Low FFP": FFP to RBC unit ratio of 0:3 to 1:3 (0.0 - 0.3) - Outcome: All-cause mortality 90 days following surgery. DATA SOURCES CPR, Danish Civil Registration System. DNPR, Danish National Patient registry. DVR, Danish Vascular registry. DPDB, The Danish national Prescription DataBase.
In this study, the investigator plan to prescribe Methylprednisolone pulse therapy in Kawasaki disease patients with coronary artery lesions or aneurysm formation beyond acute stage to investigate the role for vasculitis of KD or regression of dilatation.
Post-stent rupture of the abdominal aorta is a rare occurrence and with few publications: only 2 multicenter studies and one meta-analysis in 2017 listed this complication As well as a few cases reports This study, the first carried out in France, aims to describe the survival in patients with secondary rupture of the aneurysm despite initial treatment with EVAR.
The aim of this randomized study is to compare the safety and performance of EndoVascular Aneurysm Repair with ESAR using Endurant + Heli-FX™ EndoAnchor™ system and FEVAR using customizable grafts from Cook (Zenith Fenestrated Graft) and Terumo (Fenestrated Anaconda Graft) for the treatment of aortic aneurysms with short aortic neck (4 to 15mm).
Deep learning applied to plain abdominal radiographic surveillance after Endovascular Aneurysm Repair (EVAR) of Abdominal Aortic Aneurysm (AAA).
Spleen artery aneurysm represents the most common visceral aneurysm and the third most common splanchnic aneurysm. Most patients have no symptoms and are diagnosed as a part of other diagnostic focuses and examinations. The investigators present two patients with splenic artery aneurysms localized in the splenic hilum, who auspiciously undergo laparoscopic splenectomies with hem-o-lock clips in the vascular hilum without complications. These two cases showed that in addition to the numerous advantages of minimally invasive approaches, there is the possibility to improve laparoscopic technique in terms of safety and economic reasons by using hem - o - lock clips as a hemostatic technique securing the vascular elements of the splenic hilum.
In this research, the investigators are looking at the effects of a drug called metformin may have on the growth of abdominal aortic aneurysm (AAA)s. AAA is an abnormal enlargement of the aorta, which is the large artery in the abdomen (stomach area). The enlargement of the aorta carries a risk that it will rupture and cause life-threatening bleeding in the abdomen (belly). In this study the investigators hope to learn how metformin is associated with the enlargement or change in size of the AAA in study participants. Smaller studies have suggested that metformin may reduce the rate at which aortic aneurysms enlarge. This study will test this question: does metformin prevent AAAs from growing larger?
In recent years, many developments have been made to the tools and techniques used to treat IAs via endovascular intervention. Specifically, to the detachable coils themselves. In March 2018, the US Food and Drug administration granted Balt USA 510(k) clearance for the Optima Coil System™. Earlier this year, the list of devices included within the system has expanded to include OptiMAX Complex Super Soft and Complex Soft coils. It consists of coils that come in Standard, Soft and Super Soft profiles and allows for instant detachment from the pusher. The APPLY study is a prospective, single-center investigator-initiated study meant to assess the use of the Balt Optima™ Coil System. The site is looking to enroll approximately 30 subjects over the course of two years. The Optima Coil System™ is commercially available in the United States as such this study is looking for real-world data.
"Study on the effectiveness and safety of the coil system for the treatment of intracranial aneurysms embolization" was sponsored by Zhuhai Tongqiao Medical Technology Co., Ltd. The trial design is: prospective, multi-center, randomized, open, parallel positive control, and non-inferiority test. Purpose: To compare the data obtained by using the coil system produced by Zhuhai Tongqiao Medical Technology Co., Ltd. and the Axium Detachable Coil produced by Medtronic for the embolization of intracranial aneurysms to evaluate the effectiveness and safety of coil system for intracranial aneurysms embolization.
This is the largest study to evaluate incidence and distribution of silent cerebral infarction (SBI) following endovascular repair for disease of the aortic arch. Also, it is the first cohort to include total endovascular arch repair and devices flushed with carbon dioxide (CO2) to prevent gaseous cerebral embolization.
