Pathogenesis and prophylaxis of circulatory reactions during total hip replacement

1993

Circulatory reactions such as a drop in blood pressure, bradycardia, cardiac arrest, and even intraoperative death after insertion of the stem are well known events during total hip replacement. The present paper reports bone marrow intravasation after rise of intramedullary pressure in the femoral cavity during insertion of hip prostheses, demonstrated by intraoperative transesophageal echocardiography. In an animal study, the ultrasound echoes were identified as "mixed emboli" consisting of a core of bone marrow surrounded by thrombus. These results suggested the use of an intramedullary plug to restrict the intravasation of bone marrow. A trial was undertaken in 60 total hip replacement …

Epidural hematoma after cochlear implantation in a 2.5-year-old boy.

2005

OBJECTIVE Report a case of an epidural hematoma after cochlear implantation in a 2.5-year-old boy, the diagnostic and therapeutical emergency management, as well as the postinterventional course and rehabilitation of the child. STUDY DESIGN Retrospective case review. PATIENT Two and a half-year-old boy, suffering from early onset, profound sensorineural hearing loss had been diagnosed at an age of 1.5 years, which had been more severe on the right side initially, but had progressed to bilateral deafness. INTERVENTION AND COMPLICATION: Cochlear implantation on the left side, followed up by an extensive epidural hematoma, causing intracranial compression with a midline shift of 15 mm to the r…

Paradoxical embolism through a patent foramen ovale from central venous catheter thrombosis: A potential cause of stroke

2020

Paradoxical embolism refers to a potential condition in which an embolus arising from a venous source crosses into the systemic circulation through a right-to-left cardiac shunt causing an arterial embolism. A 39-year-old woman carrier of a central venous catheter (CVC) without evident risk factors for stroke, developed an acute right homonymous hemianopia during hemodialysis. On neuroimaging, an infarct in the territory of the left posterior cerebral artery was demonstrated. Transesophageal echocardiography revealed a patent foramen ovale (PFO) and a large fluctuating thrombus in the right atrium on the tip of the CVC, thus allowing a diagnosis of ischemic stroke from paradoxical embolism.…

Reversibilität von Veränderungen der links- und rechtsventrikulären Geometrie und Hämodynamik bei pulmonaler Hypertonie. Echokardiographische Charakt…

1997

Durch pulmonale Thrombendarteriektomie kann bei Patienten mit chronischer embolisch bedingter pulmonaler Hypertonie eine akute rechtsventrikulare Nachlastsenkung erzielt werden. Der Einflus auf die rechts- und linksventrikulare Geometrie und Hamodynamik wurde prospektiv mit Hilfe der transthorakalen Echokardiographie an einem Kollektiv von 14 Patienten (8 Frauen, 6 Manner; Alter 55 ± 20 Jahre) vor und nach 18 ± 12 Tagen postoperativ untersucht. Nach operativer Desobliteration der Pulmonalarterien fand sich eine Abnahme des invasiv bestimmten totalen pulmonalen Gefaswiderstands von 986 ± 318 auf 323 ± 280 dyn x s/cm5; p < 0,05. Der echokardiographisch erfaste systolische pulmonalarterielle D…

ORTHOTOPIC BLADDER SUBSTITUTION IN WOMEN: FUNCTIONAL EVALUATION

1999

AbstractPurpose: Orthotopic bladder substitution following cystectomy in women has recently been introduced at some specialized centers. Studies of such a procedure should consider the oncological and functional outcomes. We analyzed only the functional results of orthotopic bladder substitution since followup is too short (about 2 years) for a valid oncological assessment.Materials and Methods: From October 1994 to November 1997, 60 women with a mean age of 48.3 years underwent standard radical cystectomy and orthotopic diversion (ileal W-neobladder with subserous tunnel in 47 and hemi-Kock reservoir in 13). The oncological criterion was organ confined invasive bladder cancer.Results: Ther…

Incidence, risk factors, clinical characteristics and outcomes of deep venous thrombosis in patients with COVID-19 attending the Emergency Department…

2021

Background and importance A higher incidence of venous thromboembolism [both pulmonary embolism and deep vein thrombosis (DVT)] in patients with coronavirus disease 2019 (COVID-19) has been described. But little is known about the true frequency of DVT in patients who attend emergency department (ED) and are diagnosed with COVID-19. Objective We investigated the incidence, risk factors, clinical characteristics and outcomes of DVT in patients with COVID-19 attending the ED before hospitalization. Methods We retrospectively reviewed all COVID patients diagnosed with DVT in 62 Spanish EDs (20% of Spanish EDs, case group) during the first 2 months of the COVID-19 outbreak. We compared DVT-COVI…
