Two techniques are available for endovascular treatment of post-SAH vasospasm: mechanical angioplasty and phamacologic infusion(papaverine or other vasodilator). The advantages of papaverine infusion are simplicity, safety, and the ability to reach small distal vessels. The disadvantages are that the treatment results may be temporary and inconsistant. The advantages of balloon angioplasty are rapid, dramatic result and consistantly successful. It is important to treat vasospasm as soon as possible for two reasons: vascular response is better and permanant ischemic damage is minimized. If ischemic symptom have developed, it may already to be late. So, the treatment of vasospasm should be proreactive rather than reactive.

Snap Gauge bands were applied to measure nocturnal penile rigidity in the impotent patients and the results were compared with PBI and findings of the papaverine induced artificial erection. The results were as follows: 1. The results of Snap Gauge test were relatively competitive with the degree of erectile dysfunction which organic impotent patients complained of. 2. PBI less than 0.85 implied insufficient rigidity and PBI over 0.95 showed sufficient rigidity in Snap Gauge tests. 3. The possibility of "false positive" or "false normal" in diagnosis of the impotence was higher in the papaverine induced artificial erection tests than in the Snap Gauge tests. Conclusively, Snap Gauge band is simple to use and effective to measure quantitatively the penile rigidity reached during nocturnal erections in impotent patients.

A variety of technique of dynamic pharmacocavernosometry have been described to evaluate cavernous veno-occlusive function: however, there is no uniquely reliable and standard method so far After intracavernous (IC) injection of 45 mg papaverine and 2.5 mg phenblamine, we performed gravity cavernosometry(GC) and pump cavernosometry(PC), ie, measurement of saline infusion rate needed to obtain and to maintain an erection and measurement of pressure decay for 30 seconds and pressure drop time to 75 mmHg when pump was turned off at 150 mmHg IC pressure. Final diagnosis of venous leakage was made by cavernosoeraphy done at 90 mmHg IC pressure. The parametric values measured by each method to diagnose venous leakage and correlation among these methods were analyzed. The etiology of impotence in 45 patients studied was psychogenic in 8, venogenic in 21, combined arteriogenic and venogenic in 16. The measurement of induction flow rate was less reliable(p<0.05) for the diagnosis of venous leak than the other methods of PC and GC (p<0.01). The standard deviations of the induction and maintenance flow rate and pressure drop time were similar to or even higher than mean values. There was correlation among all these methods. Therefore, GC and PC, particularly measurement of the intracorporeal pressure decay are believed to be valuable methods for diagnosis of the corporal-venous leakage.

Penile duplex sonography with intracorporeal papaverine injection has been proposed as a reliable noninvasive method to evaluate the cavernosal arteries. To provide insight into the clinical value of this test. penile duplex sonography was comparatively analyzed with penile brachial index. nocturnal penile erection and selective internal pudendal pharmacoangiography in 60 patients suggestive of arteriogenic impotence. The duplex sonogram, penile brachial index and angiogram of both cavernosal arteries were evaluated separately and compared each other. Cavernosal arteries were interpreted as normal by duplex scanning if the artery demonstrated a 75% or greater increase in diameter and systolic peak flow velocity of greater than 25 cm/sec after intracorporeal injection of 60 mg or papaverine HCI. There was no significant difference between the degree of arterial dilatation and peak flow velocity on penile duplex sonogram. Arterial dilatation and peak flow velocity did not correlate with nocturnal penile erection and cavernosal arteriogram. But peak flow velocity correlate with penile brachial index. In conclusion. although penile duplex sonography is a useful method to evaluate the cavernosal arteries. it alone can make an error to misdiagnose the arteriogenic impotence. Therefore supplementary tests should be added to the duplex sonography to avoid this error.

This study was designed to investigate whether fibrosis of the corpus cavernoum(CC) induced by repeated intracavernous injection of papaverine HCl was related to pH of the drug. Forty-eight New Zealand White rabbits weighing 2.5kg-3.0kg were divided into 4 groups of 12 animals each. Group 1 received isotonic saline. Group 2; pH 2.0 papaverine HCl. Group 3; pH 3.0 papaverine HCl and Group 4; pH 4.0 papaverine HCl. The solution (0.1ml isotonic saline or 2mg. papaverine HCl of seeh pH) was injected intracorporeally twice every week for 6 months. Every one month since beginning of the injection, 2 animals of each group were sacrificed. the penis was observed with H and E and Masson`s lrichomme stain microscopically. No sign of Fibrosis was found in the CC of the group l even after 6months of injection. However, Group 2. 3 and 4 began to show focal of diffuse thin fibrotic changes after 2 months of injection. The fibrotic changes progressed more and more in accordance with the Frequency of papaverine HCl injection. After 4 months of injection. Group 2 showed diffuse thick fibrosis whereas Group 3 and 4 showed diffuse thin or focal thick fibrosis. In conclusion, intracavernous papaverine itself seems to play a main role to induce fibrosis of CC. However, the acidity of the papaverine HCl also might be responsible to development of the fibrosis when injected repeatedly for a long period.
