Intrahepatic pseudoaneurysm after surgical hemostasis for a delayed hemorrhage due to blunt liver injury: report of a case.

We report herein a case of delayed hemorrhage occurring after blunt hepatic trauma which was further complicated by an intrahepatic pseudoaneurysm. The delayed hemorrhage with free rupture occurred 2 weeks after the injury and the pseudoaneurysm developed 8 weeks after surgical hemostatic intervention for the delayed hemorrhage. The pseudoaneurysm was successfully treated by transcatheter arterial embolization. This rare case is reported to demonstrate the possibility of delayed catastrophic complications occurring after blunt liver injury and to point out the necessity of continued surveillance until the liver has completely healed.

Critical limb ischemia in a patient with von Recklinghausen's neurofibromatosis. Report of a case.

A 42-year-old woman complicated with neurofibromatosis underwent both balloon percutaneous transluminal angioplasty (PTA) of the iliac artery and femoropopliteal (FP) bypass grafting for critical lower limb ischemia. Seven months after the initial intervention, a recurrence of stenosis in the iliac artery and at the anastomoses of the FP bypass necessitated both PTA and a repeat thrombectomy and finally resulted in the amputation of her left thigh. This is a rarely documented case of chronic arterial occlusion associated with neurofibromatosis, in which the prognosis of arterial reconstruction for such patients is suggested to be poor.

[Regulation of progesterone accumulation in dissociated luteal cells on day 15 of pregnancy in rats].

Luteal cells from the corpora lutea of rats on day 15 of pregnancy were suspended in DMEM-F12 and progesterone accumulation was measured by radioimmunoassay. Progesterone accumulation increased steadily over eight hours and then gradually decreased. Progesterone accumulation was seen to increase with the addition of BSA and 25-hydroxycholesterol. At doses of 12 ng/ml and 600 ng/ml hCG, progesterone accumulation increased, but was seen to decrease at a dose of 30 micrograms/ml hCG. However, the addition of cyclohexamide alone had no effect on progesterone accumulation, but the simultaneous addition of cyclohexamide and hCG blocked the effects of hCG in a dose related manner. These data indicate that progesterone production by rat luteal cells depends on cholesterol availability. The results reveal that hCG stimulates progesterone production by a process requiring new protein synthesis.

Inhibitory effects of adrenocorticotrophin or corticosterone on progesterone secretion during mid-pregnancy in rats.

Conceptus number was reduced to one on Day 7 of pregnancy in rats by aspirating all but a single conceptus (Group E) or left at greater than or equal to 8 conceptuses (Group C). In Group E rats, serum progesterone concentrations remained low from Day 12 until autopsy at Day 21. Hypophysectomy on Day 12 significantly increased serum progesterone values after Day 17 of pregnancy, and these increases were blocked by treatment with ACTH (10 U/day, i.p., Days 12-17). Adrenalectomy on Day 12 also induced slight, but statistically significant, increases in serum progesterone concentration after Day 17, and these were overcome by implantation of a 10 mg capsule of corticosterone. In Group C rats, hypophysectomy or adrenalectomy on Day 12 did not change serum progesterone concentrations, but 40 U ACTH/day inhibited progesterone secretion. We conclude from these results that the pituitary-adrenal system exerts inhibitory effects on progesterone secretion during mid-pregnancy in rats.
