The influence of electrostimulation on mechanical and morphological characteristics of the triceps surae.

1994

The present study assessed the effects of training using electrostimulation of muscle (EMS) on the torque-angular velocity and torque-angle relationships, and the cross-sectional area (CSA) of the triceps surae. Twelve physical education students, divided into two groups (6 controls, 6 experimental), participated in the experiment. The EMS sessions were undertaken using a 'Complex-type' stimulator. Flexible elastomer electrodes were used. The current used discharged pulses lasting for 200 microseconds at a frequency of 70 Hz. The durations of contraction and rest were 5 and 15 s, respectively. The session lasted for 10 min for each muscle. The training regimen was three sessions per week fo…

Chimney and periscope grafts to facilitate endovascular treatment of aortic transection in a patient with aberrant right subclavian artery

2014

Purpose: To report the use of parallel grafts to extend the proximal landing zone for stentgraft repair of aortic transection involving an aberrant right subclavian artery (ARSA). Case Report: A 28-year-old patient was referred for treatment of traumatic aortic transection with contained rupture at the level of an ARSA. Immediate thoracic endovascular aortic repair (TEVAR) was planned because of hemodynamic instability. To achieve rapid sealing and maintain perfusion to both subclavian arteries, a chimney stent to the left subclavian artery (LSA) and a periscope stent-graft to the ARSA were deployed successfully. After surgical repair of all fractures, the patient was discharged 1 month aft…

X-ray computed tomography investigations of Cucuteni ceramic statuettes:

2013

Deciphering the internal structure of prehistoric artefacts can provide spectacular insights that might help us understand the people who made them. In order to preserve the integrity of these relics of past civilisations, it is desirable to make such investigations using non-destructive techniques. Recent decades have witnessed a growth in the X-ray computed tomography (CT) applications in the study of cultural heritage objects. This paper presents and discusses tomographic investigations of two Cucuteni ceramic statuettes discovered in Romania. The study was made with a CT device specially designed for archaeometric applications.

CT-Arthrographie der Schulter nach operativer Versorgung ventraler Instabilitäten

1991

25 patients who had undergone a modified Lange repair were examined postoperatively after about four years, both clinically and by CT arthrography. Ventral redislocation was no longer seen postoperatively. As regards residual ventral instability, there was agreement between CT arthrography and the clinical findings in 20/25 patients (90%). Newly developed or residual dorsal instability could be accurately demonstrated by the presence of pathological changes of the dorsal labrum and by the observation of a wide dorsal joint recess. CT arthrography did not provide reliable evidence concerning loss of function and mobility of the treated shoulder. However, the presence of marked capsular foldi…

Die Bilh�mie ? Eine seltene komplikation nach schwerster leberruptur

1990

Die traumatische Bilhdmie nach schwerster Leberverletzung ist ein seltenes Krankheitsbild und durch eine hohe Letalitat gekennzeichnet. Klinisch imponierten eine massive Hyperbilirubinamie sowie Erhohung der Gallensauren im Serum bei relativ normalen Leberzellenzymen. Pathophysiologisch liegt eine Verbindung vom Gallenwegssystem zum Niederdrucksystem der Lebervenen vor. Zur Diagnosesicherung erscheint uns neben der klinischen Symptomatik and nach vorausgegangener Sonographie and Computertomographie die ERCP als geeignetstes Untersuchungs- and Nachweisverfahren. Als Therapiemoglichkeiten kommen sowohl operative Verfahren als auch wie hier dargestellt eine erfolgreiche konservative Therapie i…

Fehlerquellen der Navigation in der lateralen Sch�delbasischirurgie

2003

Die Identifikation moglicher Storfaktoren navigationsunterstutzter Eingriffe an der lateralen Schadelbasis ermoglichen dem Anwender die Vermeidung und Behebung dieser Fehler. Anhand unserer Erfahrungen von 85 navigationsunterstutzten Eingriffen im Bereich der lateralen Schadelbasis werden Fehler der Hard- und Software, der Bildgebung und des -transfers, der Patientenregistrierung, durch den Anwender und solche strategischer Art analysiert. Bei optischen CAS-Systemen fuhrt eine Blockade des Sichtfelds der Kameras zu Funktionsbeschrankungen, wahrend elektromagnetische Systeme durch ferromagnetisch aktive Materialien beeinflusst werden konnen. Die bisherigen Verfahren der Patientenregistrierun…

Erweiterte Hemihepatektomie links mit Rekonstruktion der rechten Lebervene bei intrahepatischem cholangiozellulärem Karzinom

2016

Die erweiterte Hemihepatektomie links mit der Resektion der Lebersegmente 1, 2, 3, 4 a/b, 5 und 8 ist eine auch weiterhin sehr herausfordernde Leberresektion, deren Indikation bei gut selektionierten Patienten die Chance auf eine kurative Resektion bei primaren oder sekundaren Lebertumoren mit komplizierter Lage bieten kann. Die Morbiditat und Mortalitat ist gegenuber den nicht erweiterten Leberresektionen erhoht. Eine prazise Bildgebung und genaue Operationsplanung unter Berucksichtigung des verbleibenden Lebervolumens sowie von Einflussfaktoren wie Vorschadigungen des Leberparenchyms durch Chemotherapie oder eine Fibrose/Zirrhose ist hierbei unabdingbar. Notwendig wird dieses operative Vo…
