Chronische thromboembolische pulmonale Hypertonie: Hämodynamische Auswirkungen der selektiven Pulmonalis-DSA mit nicht-ionischem Kontrastmittel

1998

PURPOSE This study evaluates the effects of pulmonary bolus injection of nonionic contrast medium on pulmonary artery pressure and resistance in patients with chronic thromboembolic pulmonary hypertension. METHODS In 39 patients (age 52 +/- 15) haemodynamic measurements were performed during bolus injection of nonionic contrast medium in a control group (I), in moderately severe (II) and severe pulmonary hypertension (III). RESULTS Initial inspiratory arrest caused significant pressure increase in all groups prior to bolus injection (delta PAsyst: 7.1 +/- 6.7 [I], 6.8 +/- 3.9 [II] und 7.2 +/- 7.9 mmHg p < 0.05). However, contrast bolus injection (25.1 +/- 2.3 ml iopamidol, 13.0 ml/s) caused…

Retrograde Venenokklusion - Zur Therapie der verlogenen Impotenz

1993

Retrograde occlusion of penile drainage veins can produce improvement in patients with impotence due to venous leaks. We performed 50 transfemoral and three transjugular procedures; 46 (86%) were technically successful. Clinical improvement was found in 24 out of the 46 procedures (52%). In 20 patients spontaneous intercourse became possible, in four this occurred after intracavernous injection of vaso-active substances. In eleven patients there was deterioration after one to twenty months; in seven this was treated by repeated venous occlusion. In 13 patients improvement has been maintained over a period of one to thirty months (average 10.5 months). There were no complications.

Therapie thrombembolischer Verschlüsse der Unterschenkelarterien: Klinische Erfahrungen mit dem Angiojet®-Thrombektomiekatheter

1999

UNLABELLED To investigate the clinical impact of a new hydrodynamic thrombectomy catheter in thromboembolic occlusion of tibial arteries. METHOD 10 patients with thromboembolic occlusion of all tibial arteries were treated with the Angiojet thrombectomy device in order to reestablish blood flow. Depending on angiographic and clinical results of thrombectomy, additional thrombolysis, PTA, recanalization, or surgical bypass grafting was performed. RESULTS Antegrade blood flow in at least one tibial artery was reestablished in 6 cases with the thrombectomy device. However, additional treatment modalities were used in order to improve the outcome and to resolve adherent thrombi or to treat vess…

Bowel ultrasonography in acute abdomen: beyond acute appendicitis.

2021

Acute abdomen is a common reason for consultation in the emergency department. A broad spectrum of entities, including diverse diseases of the gastrointestinal tract, can cause acute abdomen. Although computed tomography is the technique most widely used to evaluate acute abdomen in the emergency department, abdominal ultrasound is often performed first and allows bowel disease to be suspected. This article describes the ultrasound features of diverse bowel diseases that can cause acute abdomen, such as acute diverticulitis, bowel obstruction, gastrointestinal perforation, bowel ischemia, intraabdominal fat necrosis, and miscellaneous processes such as endometriosis, foreign bodies, or vasc…

MR Imaging of Perianal Crohn Disease: The Role of Contrast-enhanced Sequences

2017

The MR imaging protocol described by the authors includes contrast-enhanced T1-weighted imaging with fat saturation in all patients except those with poor renal function. Horsthuis et al demonstrated in 2009 the usefulness of contrast-enhanced MR imaging for determining disease activity. Contrast agent administration is also required in case of suspicion of neoplastic tissue complicating fistulas. The joint European Crohn’s and Colitis Organisation–European Society of Gastointestinal and Abdominal Radiology guidelines report that T2-weighted images and contrast-enhanced T1-weighted images are included in the MR imaging protocol for the evaluation of perianal CD. However, as we have demonstr…

[I062] The roles of radiographers in medical imaging and radiotherapy in Europe

2018

Very fast development of technologies in medical imaging and therapy has changed the role of radiographer in Europe. Over the past ten years education and necessary skills and competencies for radiographers has become more similar in most EU countries due to input of EFRS Educational Wing, but there are still rather significant differences in the roles of radiographers between countries. Role expansion is often initiated by external and internal factors that lead to advanced practice for radiographers. However, there is also a limiting factor that functions as a barrier for development of radiographer’s role and mainly that is connected to resistance when radiologists/medical physicists obj…

Intraosseous gas distribution as a marker of postmortem interval

2020

Abstract The postmortem interval is probably the most important puzzle piece in clarifying the circumstances in case of death occurred in unknown conditions. Over the years, radio-imaging modalities have proved their worth in forensic field, providing additional and significant improvements and findings. CT-scan is characterized by wide availability, fast scan times and sustainable healthcare costs. Detection of gas, hemorrhage and bone fractures are points of strength of CT-scan. A reliable evaluation of the post-mortem interval is interesting in the victims of a mass disaster, also following a natural disaster, for the individuation of responsibility in the efficiency of the help and assi…
