Pēcimplantācijas sindroms pacientiem ar abdominālās aortas aneirismu pēc endovaskulāras aneirismas ārstēšanas
2020
Ievads: Endovaskulāra aneirismas ārstēšana (EVAR - Endovascular Aneurysm Repair) ir rutīnā izmantota metode abdominālās aortas aneirismas (AAA) ārstēšanā. Pēcimplantācijas sindroms (PIS) ir labdabīga sistēmiska iekaisuma atbilde, ko novēro pēc EVAR un kas bioķīmiski un klīniski izpaužas ar iekaisumu bez infekcijas. Laboratoriskajiem rādītājiem ir loma PIS diagnostikā. Būtiski ir to diferencēt no infekcijas. Šobrīd asinsvadu ķirurgu vidū nav vienprātības par to, kā definēt PIS - febrils drudzis ir nemainīga paradigma, tomēr leikocitozes robežvērtības definīcijās atšķiras, tādējādi ietekmējot incidenci. Ir zināms, ka febriliem pacientiem ar leikocitozi agrīnā pēcoperācijas periodā izteikti do…
Retroaortic left renal vein and inflammatory abdominal aortic aneurysm
2010
The aim of this study was to report successful surgical management of an inflammatory abdominal aortic aneurysm associated with a retroaortic left renal vein. The patient, a 78-year-old man, presented with diffuse abdominal pain, fever, and constipation. Contrast-enhanced computed tomography showed soft tissue surrounding the aneurysm and a left renal vein behind the aorta. Intraoperative findings confirmed the CT images. The patient is alive and well 6 months postoperatively.
Efficacy of TachoSil patches in controlling Dacron suture-hole bleeding after abdominal aortic aneurysm open repair
2009
Abstract Purpose The aim of this study is evaluate the efficacy of TachoSil® patches in controlling suture-hole bleeding after elective infrarenal abdominal aortic aneurysm (AAA) replacement with Dacron graft. Materials and methods Patients undergoing elective replacement of infrarenal AAA with Dacron grafts were prospectively randomized to TachoSil® patches (Group I) or standard compression with surgical swabs (Group II). We evaluated time to haemostasis, blood loss during the operation, blood loss after cross-clamp removal, duration of operation, drain volume, requirement for blood transfusion and surgeons rating of efficacy. Results Twenty patients were randomized (10 patients in each tr…
Collected World Experience About the Performance of the Snorkel/Chimney Endovascular Technique in the Treatment of Complex Aortic Pathologies
2015
OBJECTIVES: We sought to analyze the collected worldwide experience with use of snorkel/chimney endovascular aneurysm repair (EVAR) for complex abdominal aneurysm treatment. BACKGROUND: EVAR has largely replaced open surgery worldwide for anatomically suitable aortic aneurysms. Lack of availability of fenestrated and branched devices has encouraged an alternative strategy utilizing parallel or snorkel/chimney grafts (ch-EVAR). METHODS: Clinical and radiographic information was retrospectively reviewed and analyzed on 517 patients treated by ch-EVAR from 2008 from 2014 by prearranged defined and documented protocols. RESULTS: A total of 119 patients in US centers and 398 in European centers …
Comparison of the strain field of abdominal aortic aneurysm measured by magnetic resonance imaging and stereovision: a feasibility study for predicti…
2015
International audience; The prediction of the risk of rupture of abdominal aortic aneurysm (AAA) is a complex problem. Currently the criteria to predict rupture of abdominal aortic aneurysms are aneurysm diameter and growth rates. It is generally believed that study of the wall strain distribution could be helpful to find a better decision criterion for surgery of aortic aneurysms before their rupture. The wall strain distribution depends on many biological and biomechanical factors such as elastic properties of the aorta, turbulent blood flow, anatomy of the aorta, presence of thrombus or not and so on. Recently, numerical simulations to estimate rupture-potential have received many attent…
CT-Angiographie versus intraarterielle DSA bei Bauchaortenaneurysmen
1996
PURPOSE To evaluate if CT angiography is able to image all features necessary for the preoperative planning of abdominal aortic aneurysms (accessory renal arteries, stenoses or occlusions of renal and iliac arteries, patency of inferior mesenteric artery). METHODS CT angiography and DSA were performed on 27 patients with abdominal aortic aneurysms. CT angiography was performed using a protocol that covered the abdominal aorta and the pelvic arteries with a single spiral acquisition (contrast dose: 150 ml, collimation: 5 mm, table feed: 7.5 mm/s, increment of reconstruction: 2 mm). Maximum intensity projections (MIP) and axial scans were compared with the results of intraarterial DSA. RESULT…

Emergency endovascular repair of an acute aortocaval fistula with AAA: Case report and review of the literature
2009
A 72-year-old man with sudden abdominal pain and congestive cardiac failure presented a high-flow aortocaval fistula with a large abdominal aortic aneurysm as detected by Duplex ultrasonography and computed tomography angiography. As the patient’s multiple comorbidities precluded open repair, an emergency left aortouniiliac stent-graft deployment and femoro-femoral crossover bypass grafting were performed. Notwithstanding, incomplete exclusion of the fistula due to a small inflow from the contralateral iliac axis, the patient’s cardiac overload decreased with a rapid resolution of cardiac failure, allowing for a staged ligation of the right iliac artery with a complete occlusion of the aort…

Chimney and Periscope Grafts Observed Over 2 Years After Their Use to Revascularize 169 Renovisceral Branches in 77 Patients With Complex Aortic Aneu…
2013
Purpose: To evaluate the performance of periscope and/or chimney grafts (CPGs) in the endovascular treatment of pararenal or thoracoabdominal aneurysms using off-the-shelf devices. Methods: Between February 2002 and August 2012, 77 consecutive patients (62 men; mean age 7369 years) suffering from pararenal aortic (n¼55), thoracoabdominal (n¼16), or arch to visceral artery aneurysms (n¼6) were treated with aortic stent-graft implantation requiring chimney and/or periscope grafts to maintain side branch perfusion. CPGs were planned in advance and were not used as bailout. A standardized follow-up protocol including computed tomographic angiography, laboratory testing, and clinical examination…
