Primäres Leiomyosarkom der Pulmonalarterie: Inzidenz, Diagnostik und Therapie
2000
Leiomyosarkome des Herzens und der grosen Gefase sind sehr seltene hochmaligne Tumoren, die meist rasch zum Tode fuhren.¶ Wir berichten uber einen 31-jahrigen Patienten mit einem von der Pulmonalklappe ausgehenden Leiomyosarkom, das beide Pulmonalarterien und den Ausflusstrakt des rechten Ventrikels miteinbezog. Infolge der raschen Diagnosestellung und nachfolgenden radikalen Resektion ist der Patient nach mehr als 5 Jahren weiterhin tumorfrei. Nur die fruhzeitige Diagnose und komplette chirurgische Excision konnen die Uberlebenschance fur Patienten mit Pulmonalissarkomen erhohen.
Schwere sternale Wundkomplikationen nach kardiochirurgischen Eingriffen im Erwachsenenalter
2002
Schwere postoperative Wundheilungsstorungen bis hin zur kompletten Sternumdehiszenz sind gravierende Komplikationen nach medianer Sternotomie in der Herz-Thoraxchirurgie. Sie fuhren zu einer erhohten Morbiditat- und Mortalitatsrate und verursachen eine sehr viel langere Hospitalisation der Patienten als bei normaler Wundheilung. Fur das Krankenhaus entstehen daraus zusatzliche Kosten. Die vorliegende Ubersichtsarbeit beschaftigt sich mit den schweren sternalen Wundheilungsstorungen und ihrer Atiologie, Symptomen, Diagnose, pradisponierenden Risikofaktoren und Behandlungsstrategien und berucksichtigt dabei die weltweit jungste Literatur.
Single-staged laryngotracheal reconstruction for idiopathic tracheal stenosis.
2013
Background This study retrospectively evaluated the results of surgically treated idiopathic tracheal stenosis. Methods Of the 220 patients surgically treated for idiopathic subglottic and tracheal stenosis in the participating hospitals, we reviewed the surgical records of all patients with idiopathic tracheal stenosis. This subgroup required resection of all of the involved mucosa but frequently had undergone more conservative treatments that damaged the tracheal mucosa and cartilage and complicated the definitive surgical treatment. Results During the study period, 60 women (93.8%) and 4 men (6.2%), who were a mean age of 50 years (range, 19 to 77 years), were surgically treated for idio…
Validation and update of the thoracic surgery scoring system (Thoracoscore) risk model.
2020
Abstract OBJECTIVES The performance of prediction models tends to deteriorate over time. The purpose of this study was to update the Thoracoscore risk prediction model with recent data from the Epithor nationwide thoracic surgery database. METHODS From January 2016 to December 2017, a total of 56 279 patients were operated on for mediastinal, pleural, chest wall or lung disease. We used 3 recommended methods to update the Thoracoscore prediction model and then proceeded to develop a new risk model. Thirty-day hospital mortality included patients who died within the first 30 days of the operation and those who died later during the same hospital stay. RESULTS We compared the baseline patient…
Effects of the novel polymer gel LeGoo on human internal thoracic arteries.
2011
Purpose Established hemostatic devices can injure vessel wall integrity. LeGoo (Pluromed, Woburn, MA), a novel poloxamer gel with reverse thermosensitive properties, is a new device for temporary occlusion of blood vessels. The present study investigated the effects of LeGoo on vascular function and morphology. Description The distal end of the human internal thoracic artery was used to assess vascular function of LeGoo-applied segments in organ bath experiments and by scanning electron microscopy. Evaluation After LeGoo application, both maximal contractile responses to noradrenaline and endothelium-dependent relaxant responses to acetylcholine were significantly reduced. Scanning electron…
A particular phenotype of ascending aorta aneurysms as precursor of type A aortic dissection.
2012
Objectives: We aimed to identify a phenotype of ascending thoracic aortic aneurysm (TAA), which, more than others, evolves into type A dissection (TAD). Methods: Aortic specimens were obtained from patients undergoing surgical repair of TAA and TAD (108 and 26, respectively). Histopathological and immunohistochemical analyses were performed by using adequate tissue specimens, appropriate techniques and criteria. Results: We identified the three following TAA phenotypes: phenotype I (cystic medial degeneration balanced by a substitutive fibrosis, in absence of medial apoptosis and with a faint collagenase concentration), phenotype II (cystic medial degeneration of higher grade, respectively,…
Survival and reinterventions after isolated proximal aortic repair in acute type A aortic dissection.
2018
OBJECTIVES Conventional treatment for acute type A dissection is the replacement of the ascending aorta. This study demonstrates the results of a conventional approach with isolated proximal repair combined with concomitant endovascular procedures. METHODS Replacement of the ascending aorta with or without an open distal anastomosis was defined as isolated proximal repair and was performed in 562/588 patients between January 2004 and June 2017. A total of 68% were DeBakey type I and 32% were DeBakey type II aortic dissections. Concomitant procedures were thoracic endovascular aortic repair (3.6%); visceral, renal and iliac stents (2%); and peripheral bypasses (1.1%). Mean follow-up was 4.6 …
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…
Relationship between clinical and radiological signs of bronchiectasis in COPD patients: Results from COSYCONET.
2020
Bronchiectasis (BE) might be frequently present in COPD but masked by COPD symptoms. We studied the relationship of clinical signs of bronchiectasis to the presence and extent of its radiological signs in patients of different COPD severity. Visit 4 data (GOLD grades 1-4) of the COSYCONET cohort was used. Chest CT scans were evaluated for bronchiectasis in 6 lobes using a 3-point scale (0: absence, 1: ≤50%, 2: >50% BE-involvement for each lobe). 1176 patients were included (61%male, age 67.3y), among them 38 (3.2%) with reported physicians' diagnosis of bronchiectasis and 76 (6.5%) with alpha1-antitrypsin deficiency (AA1D). CT scans were obtained in 429 patients. Within this group, any sign…
