Hematoma is quite a common complication of femoral arterial catheterization. However, to the best of our knowledge, there have been no previous studies regarding deep vein thrombosis (DVT) caused by compression of a vein due to a hematoma. We report a case of a hematoma developing after femoral arterial catheterization and causing extensive symptomatic DVT. A 59-year-old male was seen in our Emergency Department with right lower leg swelling 15 days after coronary stent implantation performed using right femoral artery access. Computed tomographic (CT) scanning revealed a large hematoma (45 mm in its longest diameter) compressing the common femoral vein and with DVT from the right external iliac vein to the popliteal vein. Due to the extensive DVT involvement, we decided to release the compressed common femoral vein by surgical evacuation of the large hematoma. However, even following evacuation of the hematoma, as the DVT did not resolve soon, further mechanical thrombectomy and catheter-directed thrombolysis were performed. Angiography then showed nearly resolved DVT, and the leg swelling was improved. The patient was discharged with the anticoagulation medication, warfarin.

Group B Streptococcal sepsis and/or meningitis is one of the most serious and common diseases in the neonatal period with high mortality and frequent complications. We have experienced a case of late onset type group B streptococcal sepsis and meningitis with a complication of subclavian vein catheterization catheterization. This 29-day-old male neonate was admitted to intensive care unit with the presentation of fever and septic shock. He was born with Cesarean delivery at 36 weeks and 3 days of gestational age. He showed multiple episodes of seizure after admission and group B streptococcus was isolated from blood. CSF profiles 10 days after admission showed the features of bacterial meningitis without organism isolated. Diffuse cerebral infarction was detected on brain CT 24 days after admission. In the 13th hospital day, the complication of subclavian vein catheterization occurred; Guide wire was cut during insertion and the distal portion of it(2.5cm) was retained in the left subclavian vein. We removed the retained guide wire with goose-neck snare catheter via right femoral vein. This case was presented with a brief review of the literatures.

We have experienced ten cases of emergent operation for the complications of cardiac catheterization during the period from 1985 to September 1994.Catheterization was done for the evaluation of the cardiac or vascular problem in 8 cases and 2 cases of neurosurgical problem. The extracardiac injection of contrast material have occurred in 3 cases[primum ASD,Trilogy,VSD . Six cases were unable to remove the catheter from femoral artery or vein. The catheters were knotted, coiled, impacted or broken. An embolectomy was done 40 years old man who suffered from chronic left subclavian artery obstruction a day after angiography. Open heart surgery was performed in 5 cases of cardiac perforation,impacted catheter in left inferior pulmonary vein and broken catheter of VSD. Arteriotomy was done in 4 cases to remove the knotted and coiled catheter. There was no complication or mortality for the emergent operation.

Central analgesic effect of capsaicin was assessed by the tail flick reflex (TFR) test, using male Sprague-Dawley rats under anesthesia with pentobarbital sodium (induction with 40 mg/kg and maintenance with $4{\sim}8\;mg/kg/hr$). Level of norepinephrine in the spinal cord was also measured. Capsaicin, $35{\sim}150\;{\mu}g$, was injected intrathecally, and the TFR latency was measured before, 10, 30, and 60 minutes after the drug administration. TFR latency was increased 100% or more immediately by intrathecal capsaicin, from 2.9 seconds to the maximum of 7.0 seconds at 10 minute after the drug; P<0.01. The increase in TFR latency was maintained during the course of experiment of 2 hours. Concomitant reduction of NE content in the spinal cord was observed; from 16 ng/mg protein to 7 ng/mg protein. On the other hand, subcutaneous injection of capsaicin of 50 mg/kg did not change the TFR latency although the NE content reduced similarly to the case of intrathecal injection. Pretreatment of the animal with 0.5 mg/kg of MK-801 reversed the increase of TFR latency and NE reduction induced by intrathecal capsaicin. These results suggest that capsaicin causes analgesia at the spinal cord level by activating the excitatory amino acid-NE-dorsal horn interneurons axis of the descending inhibitory pain modulation pathway.

Purpose : The purpose of this study is to investigate the pathogens of central venous catheter-related blood stream infections and search for the association among the insertion site, the duration and the underlying conditions with the prevalence of central venous catheter-related blood stream infections under 15 years old. Methods : A retrospective study was performed from Jan, 2003 to Dec, 2003 in Severance Hospital on 112 patients who undertook central venous catheter insertions. Results : We examined 112 patients who undertook central venous catheter insertion. The mean age of patients was $4.77{\pm}4.12$ years old. Coagulase negative Staphylococci was the most common organism of central venous catheter-related blood stream infections accounting for 33.9 percent, followed by Eenterococcus faecium(9.3 percent), and Staphylococcus aureus(7.5 percent), The most common insertion site was the right femoral vein, followed by the right jugular vein and the left femoral vein. The mean insertion period was $14.17{\pm}12.00$ days. Conclusion : Central venous catheter-related blood stream infections were not only related to the underlying conditions, but also to the insertion site. We need to study the clinical importance of coagulase negative Staphylococci as it is part of the normal flora of the skin. In future, more studies are needed to take preventive measures and improve treatment methods.
