Estimation of pulmonary arterial pressure by measuring the size of the right pulmonary artery in the suprasternal echocardiogram.
1982
We studied 175 patients within 24 hr before cardiac catheterization with suprasternal echocardiography to evaluate whether pulmonary arterial hypertension can be derived by measuring the size of the right pulmonary artery. Group I consisted of 103 patients without pulmonary arterial hypertension (enddiastolic less than or equal to 12 mm Hg; mean pressure less than 20 mm Hg) and group II consisted of 72 patients with pulmonary arterial hypertension. The right pulmonary artery could be imaged in 91.2% of the patients studied. The size of the right pulmonary artery at the end of diastole in group I measured 17.9 +/- 0.2 mm (mean +/- SEM) and correlated best to the body surface area in this gro…
Bilateral DIEP Flap Breast Reconstruction to a Single Set of Internal Mammary Vessels: Technique, Safety, and Outcomes after 250 Flaps.
2019
BACKGROUND: The deep inferior epigastric artery perforator (DIEP) flap is considered the gold standard in autologous breast reconstruction. In bilateral cases, both flaps are often anastomosed to the internal mammary vessels on either side of the sternum. The authors propose a method in which both flaps are anastomosed to only the right side internal mammary artery and vein. METHODS: Between November of 2009 and March of 2018, 125 patients underwent bilateral DIEP flap breast reconstruction with this technique. One flap is perfused by the anterograde proximal internal mammary artery and the second one by the retrograde distal internal mammary artery after presternal tunneling. Patient demog…
Death of a 23-year-old man from cardiac conduction system injury through a blunt chest impact after a car accident.
2014
Abstract Cardiac contusion, usually caused by blunt chest trauma, has been recognized with increased frequency over the past decades. Traffic accidents are the most frequent causes of cardiac contusion resulting from a direct blow to the chest. Myocardial contusion is difficult to diagnose; the clinical presentation varies greatly, ranging from a lack of symptoms to cardiogenic shock and arrhythmia. Although death is rare, cardiac contusion can be fatal. The authors report a case of death due to a cardiac conduction system injury from a blunt chest impact following a car accident. The autopsy showed no external signs of thoracic trauma, no evident rib or sternum fractures. A small sub-endoc…
Early Detection of Sternal Dehiscence by Conventional Chest X‐Ray
2006
BACKGROUND Diagnosis of sternal dehiscence after sternotomy for cardiac surgery is still made clinically. The aim of this study was to identify radiographic signs of sternal dehiscence by routine chest X-ray (CXR) in patients with and without clinically diagnosed sternal dehiscence. METHODS 75 patients (group I: 65 +/- 9.3 years, f/m = 12/63) with clinically diagnosed sternal dehiscence, necessitating surgical revision and 75 patients with uneventful sternal healing (matched to group I by age, sex, preoperative risk factors and surgical procedures; group II: 66 +/- 9.0 years, f/m = 12/63) were included in this study. Serial CXRs immediately after surgery until re-intervention or discharge w…
Risk factors influencing the outcome after surgical treatment of complicated deep sternal wound complications.
2003
Background: Median sternotomy is the most frequently used incision for cardiac procedures but carries a substantial risk for deep sternal wound infections and/or sternal dehiscence. In contrast to previous studies that examined risk factors for sternal infections this study evaluates factors that lead to poor outcome after surgical revision of the non healing sternum. Methods: Between 1985 and 1999, 193 adults (mean age 64 ± 9 years, m/f = 3/1) necessitated sternal revisions (incidence 1.93%). Pre-, intra- and post-operative risk factors were evaluated for their influence on the outcome after sternal revision. Results: 65 of the 193 patients had a complicated course: ten (5.2%) died due to …
How Can We Identify the Best Implantation Site for an ECG Event Recorder?
2000
ZELLERHOFF, C., et al.: How Can We Identify the Best Implantation Site for an ECG Event Recorder? The aim of this study was to show how to find the preferable implantation site for an ECG event recorder (ECG-ER). We compared the quality of bipolar ECG recordings (4-cm electrode distance, vertical position) in 65 patients at the following sites: left and right subclavicular, left and right anterior axillary line (4th-5th interspace), left and right of the sternum (4th-5th interspace), heart apex, and subxyphoidal. The results were compared to the standard ECG lead II. In 30 patients, an additional comparison between vertical and horizontal ECG registrations was done using the same sites. ECG…
P02.40: The influence of maternal age on the association of an isolated fetal intracardiac echogenic focus and fetal aneuploidy
2006
decided to follow up the pregnancy during two weeks and perform the cordocentesis in this time, karyotope was normal. At 26 weeks we found progressive changes in fetal anatomy: heart herniation became larger, left lobe of liver began to protruse, the absence of the sternum and cartilaginous parts of the ribs was confirmed. Patient was offered pregnancy termination because of the impossibility of surgical correction. Radiography, CT and morphology of abortus confirmed ultrasound diagnosis of isolated absence of the sternum and cartilaginous parts of the ribs.
Surgical treatment of solitary sternal metastasis from breast cancer Case report
2016
Bone metastasis is a frequent and early complication of breast cancer. This case report describes a technique for a partial exeresis of the sternum and the reconstruction of the pleura with autologous dermis from the lower abdomen and the loss of substance with a myocutaneous flap.We describe the case of a 50-year old woman with a sternal excavated lesion with pathologic fracture due to an invasive adenocarcinoma, treated with a partial exeresis of the sternum and the reconstruction with a myocutaneous flap.The patient doesn't show evidence of recurrent disease and the stability of her chest well preserved.Metastatic breast cancer to the sternum, if detected early and treated aggressively, …
Die Herzpunktion bei der Ratte zur wiederholten Blutentnahme und Injektion
1971
Cardiopunkture in anesthesia is a rapid and accurate method for withdrawal of blood and injection without as many complications as suspected if carried out correctly. In the animal placed on its back a syringe with a gauge-24 needle is inserted in the left 4th or 5th intercostal space close to the sternum. When the needle is slowly pushed forward toward the spine continuous suction is exerted with the plunger. After blood has been drawn the needle is removed with a quick jerk. Thus when rats were punctured 8 to 18 times only 1 animal died of a hemopericard in 275 punctures. No other complication could be observed.
Propeller flap for treatment of a poststernotomy sternal fistula: A case report.
2014
Summary The treatment of post-operative deep sternal wound infections is a real challenge for surgeons. Conservative treatment with debridement and vacuum-assisted closure (VAC) therapy is not always successful. In the most severe and chronic cases, a surgical debridement and reconstruction of the defect is mandatory. In this report, the authors present a case of a 61-year-old female patient with a chronic cutaneous fistula in the sternal region following a median sternotomy after coronary artery bypass. The patient had already undergone treatment with antibiotics, drainage of an abscess and local debridement, but the infection continued to relapse periodically. The authors decided to treat…
