Arteriovenous shunts associated with peripheral obliterative arterial disease. Haemodynamic, arteriographic and isotope studies.

From among 210 patients with severe peripheral obliterative arterial disease, the presence of an arteriovenous shunt was demonstrated in 17 cases. Arteriovenous communications were visualized by serial angiographic records and 99mTc macroaggregate isotope testing. The regulation of the limb circulation was investigated using the venous isotope dilution method.

Limb circulation in varicosity of various types.

Regulation of limb circulation was studied by the use of the venous isotope dilution technique in 35 patients with leg varicosities. The circulatory parameters of 54 patients with normal limb circulation served as control. The various types of varicosity revealed characteristic circulatory patterns.

Lymphatic cardiomyopathy: cardiac lymphostasis in the pathogenesis of arrhythmias.

Artificial lymphatic cardiomyopathy was produced in 30 dogs by ligating the regional lymph nodes and the efferent collecting lymph trunks of the heart. In the development of cardiac lymphostasis the appearance of arrhythmias and conduction disturbances was revealed by repeated ECG recordings. The arrhythmic condition of the heart increased and pacemaker function of the sinus node deteriorated in lymphatic cardiomyopathy.
