Liver has a dual blood supply from portal vein and hepatic artery. Hepatocellular carcinoma receive their blood supply almost exclusively from hepatic artery. Thus, the concept of treating hepatocellular carcinoma by chemoembolization through these arteries is very effective. However, there may be several collateral or parasitic vessels feeding them in case of huge tumor or previous chemoembolization. We experierced a case of huge tumor involving right upper posterior portion of liver fed by 9th, 10th, 11th right posterior intercostal arteries and an anomalous hepatic artery. We tried chemoembolization with Adriamycin-Lipiodol suspension and Gelfoam material through the right posterior intercostal arteries to treat the lesion. After the procedure, the patient(55 years old female) became paraplegic with voiding and defecation difficulty which could be due to spinal cord infarction .by anterior spinal arteri. al occlusion caused by embolic material through the artery of Adamkiewicz from a posterior intercostal artery. She recovered completely after 20 days of treatment.

Pulmonary embolism is a common clinical problem in patients with immobilization, cancer, indwelling central venous catheter and surgery. However, although rare, it may occur in patients with inherited thrombophilia. Protein S deficiency is known to increase the risk of venous thrombosis and pulmonary embolism. There are many reports of venous thrombosis with protein S deficiency, but there are few reports of arterial thrombosis, especially recurrent acute pulmonary embolism. Here, we report a case of recurrent pulmonary embolism associated with type II protein S deficiency.

OBJECTIVE: To determine the age-related changes in cardiac rehabilitation (CR) outcomes, which includes hemodynamic and metabolic factors, in patients with myocardial infarction (MI). METHODS: CR was administered for 8 weeks to 32 men (mean age, 54.0±8.8 years) who underwent percutaneous coronary intervention for acute MI between July 2012 and January 2016. The exercise tolerance tests were performed before and after the CR. The results were stratified based on a cut-off age of 55 years. RESULTS: In the whole patient group, the hemodynamic variables such as the resting heart rate (HRrest), systolic blood pressure (SBPrest), submaximal HR (HRsubmax), SBP (SBPsubmax), and rate pressure product (RPPsubmax) significantly decreased and the maximal HR (HRmax) and RPP (RPPmax) significantly increased. All metabolic variables displayed significant improvement, to include maximal oxygen consumption (VO2max) and ventilation (VEmax), anaerobic threshold (AT), and the maximal oxygen pulse (O2pulsemax). However, upon stratification by age, those who were younger than 55 years of age exhibited significant changes only in the HRrest and RPPsubmax and those aged 55 years old or greater displayed significant changes in all hemodynamic variables except diastolic BP. Both groups displayed significant increases in the VO2max, VEmax, and AT; the older group also exhibited a significant increase in O2pulsemax. The magnitude of the changes in the hemodynamic and metabolic variables before and after CR, based on age, did not differ between the groups; although, it tended to be greater among the older participants of this study's sample. CONCLUSION: Because the older participants tended to show greater hemodynamic and metabolic changes due to CR, a more aggressive CR program must be administered to elderly patients with MI.

OBJECTIVE: To compare the reliability and validity of the Korean range of motion standard protocol (KRSP) for measuring joint range of motion (ROM) with those of the conventional ROM measurement using a goniometer.METHODS: We conducted a randomized controlled trial involving 91 healthy elderly individuals. We compared two strategies of measuring joint ROM to evaluate the reliability and validity of each standardized protocol: first, the KRSP based on the Chungnam National University guidelines and second, handheld goniometric measurement. In the first strategy, 3 examiners (1 rehabilitation doctor, 1 physical therapist, and 1 physical therapy student) independently measured joint ROM in 46 randomly selected subjects; in the second strategy, another 3 examiners (1 rehabilitation doctor, 1 physical therapist, and 1 physical therapy student) measured joint ROM in 45 randomly selected subjects. The reliability of each protocol was calculated using intraclass correlation coefficient, ICC(2,1), and root mean square error (RMSE).RESULTS: Both protocols showed good to excellent intra-rater reliability. With goniometer use, the inter-rater reliability was low—ICC(2,1), 95% confidence interval ranged from 0.643 (0.486–0.783) to -0.078 (-0.296–0.494)— and RMSE was high. With the KRSP, the inter-rater reliability ranged from 0.846 (0.686–0.931) to 0.986 (0.972–0.994) and RMSE was low.CONCLUSION: ROM measurements using the KRSP showed excellent reliability. These results indicate that this protocol can be the reference standard for measuring ROM in clinical settings as an alternative to goniometers.

Central venous stenosis or occlusion occurs in 11-50% of hemodialysis patients with prior subclavian vein cannulation and ipsilateral fistula or shunt. Most patients are asymptomatic but some require treatment to reduce the risk of thrombosis and improve inadequate hemodialysis pressure. In these cases, endovascular intervention, including ballooning and stenting, is a feasible strategy for selected patents. We report an unusual case of a 40-year-old man on hemodialysis that underwent endovascular stenting to treat right subclavian vein stenosis and experienced stent migration to the right ventricle, requiring surgical removal.

Gout occurs as a response to monosodium urate crystal, that is present in joints, bones and soft tissue. The classic symptoms of gouty arthritis are recurrent attacks of acute, markedly painful monoarticular or oligoarticular inflammation; but polyarthritis and chronic arthritis can also occur. Differential diagnosis from infectious arthritis is important. A definitive diagnosis requires the direct identification of urate crystals in the joint, and the exclusion of infection. We report the case of systemic inflammatory response syndrome (SIRS), developed from acute polyarticular gout. SIRS is characterized by loss of local control of inflammation, or an overly activated response resulting in an exaggerated systemic response. The SIRS was presumably due to systemic effects of a localized inflammatory response to urate crystals.

Central venous catheterization is commonly used for supplying large amounts of fluids, total parenteral nutrition and for monitoring central venous pressure. Numerous complications exist with the technique, including pneumothorax, arterial puncture with vessel injury, catheter embolus, mediastinal hematoma, hydrothorax, and the thrombus of the vein. We reported an uncommon case of pleural effusion, due to catheter tip migration and penetration, which occurred 4 days after central venous catheterization.

BACKGROUND: Sufficient blood supply through neo-vasculature is a major challenge in cell therapy and tissue engineering in order to support the growth, function, and viability of implanted cells. However, depending on the implant size and cell types, the natural process of angiogenesis may not provide enough blood supply for long term survival of the implants, requiring supplementary strategy to prevent local ischemia. Many researchers have reported the methodologies to form pre-vasculatures that mimic in vivo microvessels for implantation to promote angiogenesis. These approaches successfully showed significant enhancement in long-term survival and regenerative functions of implanted cells, yet there remains room for improvement. METHODS: This paper suggests a proof-of-concept strategy to utilize novel scaffolds of dimpled/hollow electrospun fibers that enable the formation of highly mature pre-vasculatures with adequate dimensions and fast degrading in the tissue.RESULT: Higher surface roughness improved the maturity of endothelial cells mediated by increased cell-scaffold affinity. The degradation of scaffold material for functional restoration of the neo-vasculatures was also expedited by employing the hollow scaffold design based on co-axial electrospinning techniques. CONCLUSION This unique scaffold-based pre-vasculature can hold implanted cells and tissue constructs for a prolonged time while minimizing the cellular loss, manifesting as a gold standard design for transplantable scaffolds.
