摘要:

Superficial forearm venous pressures, taken at rest and following rapid arterial occlusion, were measured in 11 normal and 14 essential hypertensive subjects, together with the changes in venous pressure induced by reflexogenic maneuvers (cold, Valsalva, hyperventilation, upright tilt) with the forearm circulation arrested. No significant difference was found in either the resting venous pressures (8.7 ± 0.9 mm Hg and 7.8 ± 0.6 mm Hg, respectively), the occluded venous pressures (20.7 ± 1.7 mm Hg and 19.7 ± 2.2 mm Hg), or the reflex venoconstrictor responses of the two groups (cold: 12.1 ± 2.7 mm Hg and 14.4 ± 2.3 mm Hg; Valsalva: 8.4 ± 2.1 mm Hg and 8.8 ± 1.2 mm Hg; hyperventilation: 7.5 ± 1.8 mm Hg and 6.8 ± 1.1 mm Hg; 50° tilt: 6.7 ± 0.9 mm Hg and 6.6 ± 1.4 mm Hg). It is suggested that, even with normal venous pressure and reflex venomotor reactivity, other venous abnormalities might explain certain hemodynamic changes observed in essential

摘要:

Intermittent claudication is caused by pain from an ischaemic muscle. Local tissue ischaemia is most often the result of an impairment of regional blood flow which is not a disease in itself but merely an event of a larger underlying disease which has to be searched for. Many conditions may induce complaints and clinical symptoms which simulate intermittent claudication but are of completely different origin. These conditions have been grouped in orthopaedic, neurologic, muscular, haematologic and metabolic disorders and were reviewed.

摘要:

This report deals with tibial arteries revascularizations performed on 28 patients since the year 1966 at the 1st Surgical Clinic of the Charles University of Prague, Czechoslovakia. Severeischemic changes with rest pain and necroses were the indications in 22 patients. In all cases a special method was used. It is a combination of semi-closed Thromboendarterectomy with saphenous vein bypass which is led along the vessels in the popliteal fossa to tibial arteries as far as the ankle region. This combination enables successful revascularization also in patients without a suitable saphenous vein.

摘要:

A superior vena cava syndrome most often results from an intrathoracic tumor; a frequent cause of the inferior vena cava obstruction is a proximal expansion of a thrombophlebitis. When both causes can be excluded and patient survives the initial symptoms for years, a chronic fibrosis in the mediastinum or (and) in the retroperitoneum have to be suspected as locations of a multifocal fibrotic diathesis.

摘要:

This is a report about two cases of alloplastic transplantation of the aorta with complete different uncommon and remote complications. The first one died by an hypotonic-ischemic malacia of the spinal cord, the other one by repeated disseminated cholesterol microembolisms of the renal arteries followed by hypertonia and ischemic necrosis of the kidney.
