PURPOSE: To report a case of bilateral ophthalmic artery occlusion in rhino-orbito-cerebral mucormycosis. METHODS: Reviewed clinical charts, photographs, and fluorescein angiography RESULTS: An 89-year-old man with poorly controlled diabetes developed sudden bilateral ptosis, complete ophthalmoplegia of the right eye, and superior rectus palsy of the left eye. Brain and orbit magnetic resonance imaging showed midbrain infarction and mild diffuse sinusitis. On the 2nd day of hospitalization, sudden visual loss and light reflex loss developed. There were retinal whitening, absence of retinal arterial filling, and a total lack of choroidal perfusion on fluorescein angiography of the right eye. The left eye showed a cherry red spot in the retina and the absence of retinal arterial filling and partial choroidal perfusion on fluorescein angiography. On rhinologic examination, mucormyosis was noticed. Despite treatment, visual acuity and light reflex did not recover and he died 4 days after admission. CONCLUSIONS: Bilateral ophthalmic artery occlusion can occur in rhino-orbital-cerebral mucormycosis.

OBJECTIVETo evaluate the etiology, diagnosis, and treatment of lower limb arterial occlusion in patients below 45 years old.

METHODSThe clinical data of 58 patients with lower limb arterial occlusion (except for Buerger's disease) below 45 years old admitted to PUMC Hospital from July 1997 to November 2007 were retrospectively analyzed.

RESULTSAmong these 58 patients, 31 patients (53.4%) had confirmed thrombophilic risk factors, including 12 patients had two or more thrombophilic risk factors. Follow-up (ranged 2-43 months, mean 10 months) showed higher rates of revascularization and amputation in patients with thrombophilic risk factors (22.6% and 22.6%, respectively) than in those without thrombophilic risk factors (14.8% and 11.1%, respectively) (P > 0.05). Among patients with two or more thrombophilic risk factors, the rates of revascularization and amputation were 25.0% and 33.3%, respectively.

CONCLUSIONSLower limb arterial occlusion in young adults is often caused by thrombophilic risk factors. Attention should be taken to identify these etiologies before surgical treatment.

OBJECTIVETo assess the value of magnetic resonance imaging (MRI) in mid- and long-term complication monitoring after liver transplantation.

METHODSTwenty-one recipients receiving orthotropic liver transplantation between Feb 2003 and May 2005 were enrolled in this study. FLASH T(1)-weighted, T(2)-weighted fast spin echo, T(2)-weighted fat suppression, dynamic gadolinium-enhanced, MR cholangiopancreatography (MRCP) and three-dimensional dynamic gadolinium-enhanced FISP MRA images were obtained.

RESULTSOf the 21 patients, bile duct complications were detected in all cases and liver arterial and venous complications in 8 cases. Liver cancer relapse occurred in 5 cases and allograft failure in 4.

CONCLUSIONMR imaging allows effective monitoring of mid- and long-term complications of liver transplantation, which provides valuable clues for their clinical treatment.

We report here a case with hypereosinophilia and peripheral artery occlusion. A 32-yr-old Korean woman presented to us with lower extremity swelling and pain. Angiography revealed that multiple lower extremity arteries were occlusive. The biopsy specimen showed perivascular and periadnexal dense eosinophilic infiltration in dermis and subcutaneous adipose tissue. Laboratory investigations revealed a persistent hypereosinophilia. She was prescribed prednisolone 60 mg daily. Her skin lesion and pain were improved and the eosinophil count was dramatically decreased. After discharge, eosinophil count gradually increased again. Cyanosis and pain of her fingers recurred. She had been treated with cyclophosphamide pulse therapy. Her eosinophilia was decreased, but the cyanosis and tingling sense were progressive. The extremity arterial stenoses were slightly progressed. Skin biopsy showed perivascular eosinophilic infiltration in the dermis and CD40 ligand (CD40L) positive eosinophilic infiltration. The serum TNF-alpha was markedly increased. These results suggest that CD40L (a member of TNF-alpha superfamily) could play a role in the inflammatory processes when eosinophil infiltration and activation are observed. We prescribed prednisolone, cyclophosphamide, clopidogrel, cilostazol, beraprost and nifedipine, and she was discharged.

We report a case of ophthalmic artery obstruction combined with brain infarction following periocular autologous fat injection. The patient, a 44-year-old woman, visited our hospital for decreased visual acuity in her left eye and dysarthria one hour after receiving an autologous fat injection in the periocular area. Her best corrected visual acuity for the concerned eye was no light perception. Also, a relative afferent pupillary defect was detected in this eye. The left fundus exhibited widespread retinal whitening with visible emboli in several retinal arterioles. Diffusion-weighted magnetic resonance imaging of the brain showed a hyperintense lesion at the left insular cortex. Therefore, we diagnosed ophthalmic artery obstruction and left middle cerebral artery infarction due to fat emboli. The patient was managed with immediate ocular massage, carbon dioxide, and oxygen therapy. Following treatment, dysarthria improved considerably but there was no improvement in visual acuity.

Acute arterial occlusion is a rare complication following total knee arthroplasty (TKA). The incidence as reported previously is from 0.03% to 0.17%; however, the sequelae can be disastrous because of its potential threat to limb loss.We report a case of acute arterial occlusion in the midpiece of femoral artery following TKA occurred 40 min postoperatively. The occlusion site existed at the midpiece of femoral artery is uncommon. Arterial circulation of the lower limb could not be restored by the thrombolysis and thrombectomy treatments performed within 11 h after TKA. In the end, amputation had to be carried out. In the treatment of acute arterial occlusion following TKA with a tourniquet, it is important to fully consider that arteriosclerosis may induce atheromatous plaque disruption, which might be the reason for acute arterial occlusion.
