Recent advances in the understanding of erectile physiology have improved the prompt diagnosis and treatment of priapism. During initial assessment, the physician must distinguish between veno-occlusive low flow (ischemic) and arterial high flow (nonischemic) in order to choose the correct treatment option for each type of priapism. Patient history, physical examination, penile haemodynamics and corporeal metabolic blood quality assist the distinction between static and dynamic priapism. Normally, priapism is effectively treated with intracavernous vasoconstrictive agents or surgical shunting. However, when these two methods fail, subsequent treatment procedures are a matter for debate. Alternative options, such as intracavernous injection of methylene blue or selective penile arterial embolization, for the management of high and low flow priapism are described and a survey of current treatment modalities is presented. 相似文献

Hypertension in the elderly: Age- and disease-related complications and therapeutic implications 总被引:1,自引:0,他引:1

Summary Effective treatment of hypertension in the elderly requires an understanding of both the progressive course of the disease and the impact of aging on the cardiovascular system, including physiological, genetic, lifestyle, and environmental factors. Review of the literature that has attempted to define the impact of an aging process on cardiovascular structure and function reveals a diversity of findings and interpretations. However, in general, normotensive elderly subjects exhibit the heart and vascular characteristics of muted hypertension, including many features of younger hypertensive patients: cardiac hypertrophy, diminution in resting left ventricular early diastolic filling rate, increased arterial stiffness and aortic impedance, diminution in the baroreceptor reflex, a diminished response to catecholamines and diminished renal blood flow, and an increase in peripheral vascular resistance (PVR). Treatment of elderly hypertensives is more challenging because of the greater likelihood of the presence of concomitant diseases, most importantly, coronary and peripheral atherosclerosis, renal dysfunction, and diabetes mellitus. Isolated systolic hypertension (ISH), the most common form of hypertension in the elderly, has also been clearly shown to be an important predictor of cardiovascular morbidity and mortality, including coronary artery disease, congestive heart failure, and stroke. Treatment of ISH has been shown to lower systolic pressure safely and effectively in the elderly. By reducing PVR, and possibly the arterial stiffness, and thus the early reflected pulse waves, vasodilators, including calcium antagonists, may lower these three components of arterial impedance, and hence lower the arterial load on the heart. The cardiac hypertrophy and reduced left ventricular filling rate associated with hypertension in older individuals can also be ameliorated, to some extent, by calcium channel blockers.Proceedings of a symposium held in Atlanta, Georgia on March 2, 1991. 相似文献

Summary Blood (3.4–13.5% of blood volume) was pumped in and out of the circulation of rats at different rates and period lengths during continuous measurements of blood conductivity (reciprocally related to hematocrit) and arterial pressure. Hct followed the same zig-zag course as the induced changes of blood volume in every case, indicating that fluid shifts (v) between interstitium and intravascular space closely follow blood volume changes. As the het increase during reinfusion was not as great as the preceding decrease, hct dropped continuously during the 20–90 minutes of experimentation, so that a final volume increase (v) by about 4% was calculated, which was confirmed by a corresponding decrease of plasma protein concentration. Both final v and v during periodic volume change (% B.V.) were greater when arterial pressure dropped. v was directly related to % B.V. but not to its rate of change. Heart rate dropped slightly at the end of the reinfusion periods, whereas it rose to control at the end of the withdrawal periods. The results were regarded as evidence of blood volume regulation proportional to the absolute volume of blood lost in non-hypotensive hemorrhage.Supported by DFG-grant AZ 3/3 相似文献

Summary 20 patients (12 female) with moderately severe essential hypertension [blood pressure during placebo treatment 181±6 (systolic), 107±3 (diastolic)] completed a double-blind, cross-over dosetitrated comparison of labetalol and methyldopa. Both drugs reduced lying and standing arterial blood pressure to a similar extent, although only labetalol reduced heart rate. Compliance was high (>95%) with both drugs, and the incidence of subjective adverse effects was similar. 相似文献

Summary Six normal volunteers were studied on four separate occasions. On each occasion they received two concomitant infusions which were either placebo/placebo, placebo/tyramine, angiotensin II/placebo or angiotensin II/tyramine. Angiotensin II infusion was given at a constant rate of 2ng/kg/min whereas the tyramine infusion consisted of 10 min increments at 1.25, 2.5, 3.75, 5, 7.5 and 10 g·kg–1·min–1.Tyramine infusion caused a dose dependent increase in systolic blood pressure with increases in diastolic blood pressure and plasma noradrenaline only at the highest doses. These changes were not affected by concomitant angiotensin infusion.We have therefore found no evidence to support the enhancement of haemodynamic or plasma noradrenaline responses to tyramine infusion by low dose infusion of angiotensin II in man. 相似文献

Selective arterial embolization in the treatment of aneurysmal bone cyst and angioma of bone 总被引:8,自引:0,他引:8

Nineteen aneurysmal bone cysts and five angiomas of bone were treated by selective arterial embolization. The median follow-up was 22 months. In 17 patients healing occurred with complete relief of symptoms; in 11 of these almost complete ossification of the lesion resulted. In the remaining cases, little or no ossification was apparent but ossification may take 1 year or more to occur. No recurrence was observed in any of these cases. Recurrence occurred only in two cases. In one, growth of the recurrence stopped after a second embolization, and the X-rays showed no change. Selective arterial embolization represents a treatment of choice in aneurysmal bone cyst and angioma of bone especially of the spine, sacrum, or pelvis. In these sites embolization replaces surgery which might be hazardous due to intraoperative bleeding.Supported in part with Rizzoli Research Funds 相似文献

We report here a 54-year-old man with an aneurysm arising on a cervical anterior radiculomedullary artery. The aneurysm ruptured
just after vertebral angiography for a vascular anomaly of the brain, and it appeared to be fusiform, with thrombosis following
angiography. Considering the sequential radiological studies and clinical course, it was assumed to be a dissecting aneurysm
caused by the angiography. MRI showed severe swelling of the cervical spinal cord and an infarct in the territory of the anterior
spinal artery. The mechanism of this rare complication is discussed.
