ABSTRACT
OBJECTIVE: We wanted to valuate the mid-term therapeutic results of percutaneous transhepatic balloon angioplasty for portal vein stenosis after liver transplantation. MATERIALS AND METHODS: From May 1996 to Feb 2005, 420 patients underwent liver transplantation. Percutaneous transhepatic angioplasty of the portal vein was attempted in six patients. The patients presented with the clinical signs and symptoms of portal venous hypertension or they were identified by surveillance doppler ultrasonography. The preangioplasty and postangioplasty pressure gradients were recorded. The therapeutic results were monitored by the follow up of the clinical symptoms, the laboratory values, CT and ultrasonography. RESULTS: The overall technical success rate was 100%. The clinical success rate was 83% (5/6). A total of eight sessions of balloon angioplasty were performed in six patients. The mean pressure gradient decreased from 14.5 mmHg to 2.8 mmHg before and after treatment, respectively. The follow up periods ranged from three months to 64 months (mean period; 32 months). Portal venous patency was maintained in all six patients until the final follow up. Combined hepatic venous stenosis was seen in one patient who was treated with stent placement. One patient showed puncture tract bleeding, and this patient was treated with coil embolization of the right portal puncture tract via the left transhepatic portal venous approach. CONCLUSION: Percutaneous transhepatic balloon angioplasty is an effective treatment for the portal vein stenosis that occurs after liver transplantation, and our results showed good mid-term patency with using this technique.

The authors experienced one case of Gronblad-Strandberg syndrome with subretinal neovascularization which showed characteristic signs of pseudoxanthoma elasticum(PXE) and angioid streak. PXE is an uncommon hereditary disorder which involves the elastic tissue of the dermis and may also involve the eye and the cardiovascular system. Angioid streaks are red or dark-brown jagged irregular lines extending in spoke like fashion toward periphery from an area of peripapillary atrophy. We report a case of Gronblad-Strandberg syndrome with subretinal neovasculari zation in a 49 year old korean female.

To evaluate the availability of n-butyl-2-cyanoacrylate as an adhesive in limbal wound repair, we used 15 rabbits(30 eyes). A limbal incision exactly 9mm long was made and the wound of one eye was tightly closed with seven equally apaced corneoscleral sutures of 10-0 nylon(nylon group), The wound of the other eye was closed by two(6.5mm spaced, 11 and 1 o'clock) corneoscleral sutures of 8-0 vicryl and the outer surface of this limbal wound was thinly coated with a small amount of Histoacryl(Histo-acryl group). The average disrupting pressure in nylon group was 0.87 +/- 0.11 kg/cm2 and that in Histoacryl group was 0.79 +/- 0.17 kg/cm2. The average refractive change in nylon group was 2.5 diopter with-the-rule astigmatism, and that in Histoacryl group was 0.9 diopter against-the-rule astigmatism. A moderate inflammatory reaction was noted at the histopathologic findings of the wounds closed with Histoacryl 14 days after operation. From the results, post-operative inflammatory changes indicated that the Histoacryl seemed to be rather unsuitable for clinical application.
