Hemodynamic monitoring and management in patients undergoing high risk surgery: a survey among North American and European anesthesiologists

2011

Abstract Introduction Several studies have demonstrated that perioperative hemodynamic optimization has the ability to improve postoperative outcome in high-risk surgical patients. All of these studies aimed at optimizing cardiac output and/or oxygen delivery in the perioperative period. We conducted a survey with the American Society of Anesthesiologists (ASA) and the European Society of Anaesthesiology (ESA) to assess current hemodynamic management practices in patients undergoing high-risk surgery in Europe and in the United States. Methods A survey including 33 specific questions was emailed to 2,500 randomly selected active members of the ASA and to active ESA members. Results Overall,…

Elevated systolic pulmonary artery pressure for prediction of myocardial necrosis and right ventricular dysfunction in acute pulmonary embolism

2016

Kontext: Echokardiografie je v soucasnosti hlavni metodou pro vysetřeni dysfunkce prave komory (right ventricular dysfunction, RVD) u akutni plicni embolie (PE). Dysfunkce prave komory je sice spojena s nepřiznivou prognozou, dosud vsak nebyla přijata žadna obecně uznavana definice. Systolický tlak v plicnici (systolic pulmonary artery pressure, sPAP) větsinou neni soucasti kriterii RVD. Cilem nasi studie bylo zhodnotit možnost použiti sPAP v predikci nekrozy myokardu a RVD u akutni PE.Metody: Retrospektivně byly analyzovany udaje 182 pacientů s akutni PE. Pacienti s PE a hodnotami sPAP ≤ 30 mm Hg byli srovnavani s pacienty s PE a hodnotami sPAP > 30 mm Hg. Vztahy mezi sPAP na jedne straně …

Surgical management of moderate ischemic mitral valve regurgitation: Where do we stand?

2014

Ischemic mitral regurgitation (IMR) represents a common complication after myocardial infarction. The valve is anatomically normal and the incompetence is the result of papillary muscles displacement and annular dilatation, causing leaflets tethering. Functionally the leaflets present a restricted systolic motion due to tethering forces that displaces the coaptation surface toward the left ventricle apex. The patients present poor left ventricular function at the time of surgery and the severity of the mitral regurgitation increases the risk of mortality. Currently there is general agreement to treat surgically severe IMR nevertheless strong evidences for patient with moderate insufficiency…

Emergency Endovascular Treatment of Petrous Carotid Artery False Aneurysm

2015

Abstract Introduction The management of ruptured intracranial false aneurysms (IFAs) might be tricky as any kind of treatment modality, surgical or endovascular, is burdened with significant challenges. A case report of the endovascular treatment of IFA in emergency setting is presented to provide more understanding of its pathophysiology as well as of the best operative work-up for petrous carotid artery reconstruction. Methods Technical notes from a left sided skull base abscess, involving and eroding the carotid canal and petrous carotid artery (PCA) resulting in an IFA are shown and analyzed. Results Balloon-assisted low viscosity Onyx embolization seems an effective method for the emer…

Predictors of carotid artery in-stent restenosis

2012

SummaryBackgroundCarotid angioplasty and stenting (CAS) is increasingly being used as a treatment alternative to endarterectomy (CEA), especially in patients aged <70 years with significant carotid artery stenosis. However, an in-stent restenosis (ISR) might endangering the long-term efficacy of CAS. The aim of this article was to review the current literature regarding incidence and clinical significance as well as predictors of in-stent restenosis.MethodsWe conducted a systematic review of the literature to identify all studies on the abovementioned factors.Results3 randomized-controlled trials comparing CAS and CEA and 13 single centre studies fulfilled our inclusion criteria. The occurr…

An unusual internal carotid artery compression as a possible cause of Eagle syndrome – A novel hypothesis and an innovative surgical technique

2019

Background: Eagle syndrome (ES) is a rare symptomatic condition generally caused by an elongated styloid process (SP) or calcification of the stylohyoid complex. On the diagnosis is made, its treatment remains subjective since the indications for surgical intervention are still not standardized. Although styloidectomy is the surgical treatment of choice, no consensus exists regarding the transcervical or/and transoral route. Here, we report our experience in a patient with bilateral internal carotid artery (ICA) dissection caused by ES, who underwent innovative surgical technique. Case Description: A 53-year-old man, with the right-sided middle cerebral artery acute stroke, underwent compu…

Gefäßrekanalisation mit einem elektrischen Thermokauter-Katheter -In-vitro-Erfahrungen mit einem neuen Kathetersystem

1988

Recanalisation of arteriosclerotic occlusions by means of laser angioplasty, Kensey catheter and the "hot tip" catheter is undergoing early, successful clinical trials. The thermo-cautery catheter described in this paper uses the well known technique of cutting with high frequency electric currents in order to achieve vascular recanalisation. Seven attempts were made to recanalise occlusions at post mortem; four were successful, but perforation occurred in three. Histologically we found a narrow rim of carbonisation of tissues surrounded by a zone of homogenisation and a transitional zone.

The use of a proximal protection system, a reperfusion catheter, and new-generation mesh stents in combined endovascular therapy for a long, symptoma…

Color Doppler imaging of the eye and orbit A synopsis of a 400 case experience

2009

Color Doppler imaging (CDI) is a recent advance in ultrasonography that allows simultaneous two-dimensional imaging of structure and blood flow. Doppler information is superimposed in color over a conventional gray-scale ultrasound image. Using this technique we have examined 400 eyes. The central retinal artery, posterior ciliary arteries, ophthalmic artery, the central retinal vein and the vortex veins could be located in all normal eyes. Using the color image as a guide, Doppler spectral analysis is used for quantitative assessment of blood flow velocity in these vessels. We also studied patients with intraocular tumors, arterial and venous retinal occlusions, orbital vascular anomalies …
