  • Negative pressure pulmonary edema (NPPE) during anesthetic recovery is a rare, but potentially serious complication for patients who are undergoing different surgical procedures. The proposed mechanism is the generation of high negative pressure during markedly respiratory effort and upper airway obstruction from glottis closure and laryngospasm, and this all leads to pulmonary edema. We report here on a case of a healthy 26-year-old male who immediately developed NPPE and hemoptysis following extubation after partial rib resection due to benign rib tumor; the patient was treated conservatively. We also include a review of the review literatures.

  • Among the causes of SVC syndrome, intraluminal tumor, especially the leiomyosarcoma is very rare. We report a 39 year old female patient who had been suffering from headache and facial edema for 6 weeks before admission. On physical examination, facial edema and venous engorgement on upper extermities and upper chast wall were showed. The chest CT scan and SVC cavogram showed a long intraluminal mass lesion resulting in a near total obstruction of the SVC Surgery was performed through median sternotomy. For complete resection of the tumor and thrombus, we used partial and total CPB. The follow up SVC cavogram revealed no abnormality 14 months after the operation.

  • 71 years old man was operated on due to abdominal aortic aneurysm associated with complete occlusion of left common iliac artery. The coexisting chronic deep vein thrombosis of the left femoral and iliac vein was not diagnosed preoperatively. Resection of aneurysm and Y-graft interposition was performed. Recurrent edema and pain occured to the left lower extremity immediately postoperatively, which aggrevated with the lapse of time, resulting in fatal extensive venous thrombosis. This report regards the surgical treatment and complication of the aortoiliac occlusive disease associated with chronic deep vein thrombosis.

  • Purpose : To evaluate the late effect(3 and 6 months) of cis-diarnrninedichlo-roplatinum(II)(cisplatin) on the radiation brain damage when the cisplatin was intraperitoneally infused immediately after whole brain irradiation in the rats. Materials and Methods : The histolopathological findings of the brain were examined in rat brains at 3 and 6 months after the treatment. The rats were irradiated(20 or 22.5 Gy, RT) or cisplatin was injected intraperitoneally(2,4, or 8mg/kg, CT) and in combined treatment group, cisplatin(2mg/kg) was injected immediately after irradiation(20 or 22.5 Gr). Histopathological examination was done mostly in irradiation or cisplatin alone groups, because the rats in combined group died during experimental period except 2 rats. Results : The rats treated with cisplatin showed marked epithelial vacuolation with perivascular edema and vascular dilatation in choroid plexus at 3 months as well as multifocal necrosis involving fimbria and cerebellar hemispheres at 3 and 6 months. The changes were more prominent in rats with 2mg/kg injection compared to rats with 8mg/kg injection. The rats with RT and combined CT and RT showed characteristic delayed irradiation effects such as focal coagulation necrosis and vascular changes, which were more marked than previous reports Prominent perivascular and leptomenin-geal astrocytic Proliferation was well documented by anti-GFAP antibody. Cisplatin treatment did not enhance the effect of radiation-induced changes of blood vessels and astrocytic proliferation. Conclusion : The focal necrosis was the most consistently noted finding in this study, it suggested the possibility to use this as an evaluation factor for combined effects of RT and cisplatin.

  • Purpose: Intravitreal aflibercept, ranibizumab, bevacizumab, and dexamethasone are the most widely used drugs in the treatment of diabetic macular edema (DME). The aim of this study was to compare the efficacy and safety of anti-vascular endothelial growth factors and dexamethasone for the treatment of DME. Methods: There were nine previous systematic reviews on this topic; we updated these high-quality reviews. Seven studies were added to two studies following a literature search. Efficacy outcomes were 1) average improvement in visual acuity, 2) proportion of patients who experienced an improvement in vision (an increase in best-corrected visual acuity (BCVA) of ${\geq}15$ in the Early Treatment Diabetic Retinopathy Study [ETDRS]), and 3) proportion of patients who experienced worsening vision (a decrease in BCVA of ${\geq}15$ in the ETDRS). Safety outcomes included systemic adverse events and ocular-related adverse events. Results: The mean difference in the BCVA for ranibizumab versus bevacizumab treatment was 0.16 (95% confidence interval [CI]: -0.02, 0.34), and that for ranibizumab versus aflibercept was -0.08 (95% CI: -0.26, 0.10). The mean difference in the change of BCVA for aflibercept versus ranibizumab was -0.20 (95% CI: -0.40, -0.01), and that for aflibercept versus bevacizumab was -0.34 (95% CI: -0.53, -0.14). Other efficacy outcomes showed similar trends, and there was no significant difference between treatments. There was also no significant difference in both systemic and ocular adverse events rates between the treatments. Conclusions: In DME patients, the efficacy of aflibercept was found to be higher with respect to BCVA changes compared with ranibizumab or bevacizumab. However, there were no significant difference in terms of visual acuity improvement or visual acuity of more than 15 letters, nor in terms of anti-vascular endothelial growth factors (as a safety outcome).

  • May-Thurner syndrome (MTS), also known as iliac vein compression syndrome, is a condition, in which compression of the common venous outflow tract of the left lower extremity can cause discomfort, swelling, pain or blood clots in the iliofemoral veins. The problem is due to left common iliac vein compression by the overlying right common iliac artery. This paper describes the case of a 75-year-old female with MTS after performing right total knee replacement arthroplasty. The authors diagnosed MTS through intravenous angiography and angiographic computed tomography on swelling and pain of the left lower extremities after performing right total knee replacement arthroplasty. The thrombus was removed using a thrombolytic agent and mechanical thrombectomy, and an intravenous stent then inserted after angioplasty. No case of MTS after performing total knee replacement arthroplasty has been reported in Korea. Therefore, this case is reported along with review of the relevant literature.

  • A 13-year-old, female, Shih-tzu and a 10-year-old, female, Yorkshire terrier were presented with ulcerative keratitis caused by corneal endothelial degeneration. Generalized corneal edema, conjunctival hyperemia, focal corneal pigmentation, corneal neovascularization, sub-epithelial bullae, and positive fluorescein staining were observed during ophthalmic examinations. Thermokeratoplasty was performed on the overall edematous corneas. Healing of the cornea was completed within 25 days and corneal ulceration has not recurred after healing of the cornea in both cases. Other ocular complications were not observed except for a slight increase in corneal pigmentation. According to this study, thermokeratoplasty could be an effective treatment for corneal ulceration secondary to corneal endothelial diseases in dogs.

  • The purpose of this study was to analyze the effect of single-fraction stereotactic radiosurgery (SRS) for the treatment of 15 cases of cerebral arteriovenous malformations (AVMs). Between 2002 and 2009, of the 25 patients who had SRS for the treatment of cerebral AVM, 15 patients (6 men, 9 women) taken a digital subtraction angiography (DSA) over 12 months after SRS were included. We retrospectively evaluated the size, location, hemorrhage of nidus, angiographic changes on follow-up on the MR angiography and DSA, and clinical complications during follow-up periods. At a median follow-up of 24 months (range 12-89), complete obliteration of nidus was observed in all patients (100%) while residual draining veins was observed in 3 patients (20%). There was no clinical complication during the follow-up period except seizure in 1 patient. The mean nidus volume was 4.7cc (0.5~11.7 cc, SD 3.7 cc). The locations of nidus were in cerebral hemisphere in 11 patients, cerebellum in 2 patients, basal ganglia in 1 patient, and pons in 1 patient respectively. 9 cases were hemorrhagic, and 6 cases were non-hemorrhagic AVMs. The SRS with LINAC is a safe and effective treatment for cerebral AVMs when the follow up period is over 4 years. However, it is recommended to continue to follow up until the draining vein on arterial phase of follow up DSA disappears completely.

  • Background : Varicose vein is a very common vascular disease and has recently become a matter of concern for thoracic and cardiovascular surgens. Material and Method : We analyzed 209 cases or 269 feet with varicose vein retrospectively, which had been treated in our hospital from April 1999 to December 2000. Result : Male : Female ratio was 1:3(Male : 52 cases, Female : 157 cases), mean age was 42.2$\pm$9.7 years old, mean duration of varicosities was 12.2$\pm$9.7 years, and mean follow up was 14.8$\pm$6.1 months from July 2001. Most common symptom was leg pain(122 cases, 58.4%). Long standing job(44 cases), pregnancy(37 cases), and family history related to varicose vein came to 79.9% as the major predisposing or precipitating factors. Anatomic classifications of main lesion were GSV (greater saphenous vein,126 cases), LSV(lesser saphenous vein,18 cases), and reticular veins and telangiectasias(65 cases). Main treatments were stripping of GSV, stab avulsion, ligation of saphenofemoral junction, sclerotherapy, and conservative treatment. Comparing A group (stripping of GSV) with B group(sclerotherapy of GSV), A group had more complications than B group; however, A group had less recurrences than B group(p 0.05). Comparing C group(stab avulsion of LSV) with D group(sclerotherapy of LSV), there were 2 cases of recurrence in D group; however, there were no statistical differences between the two groups in complication and recurrence(p>0.05). Comparing B group(sclerotherapy of GSV) with E group(sclerotherapy of reticular vein and telangiectasia), there were no differences in complication; however, B group had more recurrences than E group. Post-stripping complications were ankle numbness and tingling(2 cases), ankle pain(2 cases),ankle swelling(2 cases), and wound pain(1 case). Postsclerotherapy complications were thrombophlebitis(1 case) and skin ulcer(1 case). Conclusion: Sclerotherapy for varicose vein involving GSV had more recurrences than stripping for lesions involving GSV. Sclerotherapy for reticular vein and telangiectasia had less recurrences than sclerotherapy for lesion involving GSV. Sclerotherapy is a very convenient method without operation and admission, thus further research is demanded in case of varicose vein involving GSV.
