[Step-wise diagnosis of primary and secondary lymphedema].

The diagnosis of the lymphatic oedema is possible by means of non-invasive methods. The degree of severity of the lymphatic oedema can already be assessed within the basic diagnostics (anamnesis, clinical findings). The recognition of secondary lymphatic oedemas is important, particularly of those due to tumours of pelvic organs. Indications and contraindications of other diagnostic methods (plethysmography, dye test, computer tomography, sonography, lymphography) in diseases of the lymphatic vessels are presented.

[Effect of varicose vein sclerotization on the venous hemodynamics of the lower extremities].

Plethysmographic examinations on 47 females with slight primary varicosis to primary varicosis of medium degree resulted in excessive values of the swelling inclination and the change of the venous capacity V30 compared with the normal values reported in literature, whereas the venous regurgitation was in the superior normal region. By sclerosation treatment no significant change of the pathological venous measuring values could be achieved. In a good cosmetic success and directed influence of the locally disturbed haemodynamics could, therefore, not be spoken about the restoration character of the sclerosation treatment for the disturbed venous haemodynamics.

[Cardiovascular radiography, changes in the thoracic aorta, ECG and clinical parameters in hypertension. 2. Changes in the thoracic aorta in hypertension].

In 142 hypertensives and a control group of 230 normotensives the measure of the aorta after Kreuzfuchs was estimated. In the two groups a significant increase of the width of the aorta was found with growing age. Whilst the width of the aorta concerning the degree of severity I of hypertension on an average were slightly below those of normotensives, they were increased in the degrees of severity II and III, but a further increase could not be ascertained at the transition from degree of severity II to III. On the other hand, the duration of hypertension is of particular importance when a dilation of the aorta is present. Also between deformation of the heart and measure of the aorta close relations which may conclude to a homogenous development are to be seen particularly in the younger patients. The influence of the sclerosis of the aorta in the sense of an additional dilation of the aorta could not be clearly confirmed on the basis of our material. On the other hand, the frequency of calcium depositions significantly increased with growing age in the region of the aortic arce and in the group of younger patients with the duration of hypertension, whereas the different degrees of severity II and III had a smaller influence. It is interesting that several patients showed normal widths of the aorta despite a duration of the hypertension of more than 5 years and a degree of severity III.

[Cardiovascular x-ray findings, changes of the thoracic aorta, electrocardiographic and clinical parameters in hypertension. 1. Cardiovascular x-ray findings in hypertension].

We examined 142 hypertensive patients of special consulting hours for hypertension. In a subdivision into 3 degrees of severity of hypertension and into the age groups less than or equal to 50 years and greater than 50 years X-ray findings on the heart and on the large vessels near the heart were made. Patients with blood pressure values RRs greater than or equal to 160 Torr and RRd greater than or equal to 95 Torr had these findings in 78%. 56% of the test persons with a heart affected in the left ventricle (R1) were found and 23% of the test persons with left-prevailing heart affected on the two sides (R3). The positive correlation between age of the patients with hypertension, duration of hypertension and frequency of the heart deformation in the sense of the left-ventricularly affected heart and the left-prevailing heart affected on the two sides could statistically be ascertained. 62% of the patients less than or equal to 50 years and 89% of the patients greater than 50 years had these findings. In a duration of hypertension less than or equal to 5 years 64% had these findings, in a duration of hypertension greater than 5 years 64%. The total number of findings increases with the degree of severity of hypertension. In test persons with degree II of severity of hypertension (RRs 160-200 Torr, RRd greater than or equal to 95 Torr) 73% had these findings, in test persons with degree III (RRs greater than Torr, RRd greater than or equal to Torr) 86%. The relation of the heart deformation in the sense of the left-prevailing heart affected on the two sides between degree II and III of the severity of hypertension was contradictory. In hypertension II and duration of hypertension greater than 5 years the percentage of the test persons with left-prevailing heart affected on the two sides was 42%, in hypertension III and duration of hypertension greater than 5 years 19%.
