Carpal tunnel syndrome is the most common peripheral nerve entrapment syndrome that characterized by pain, especially in night, sensory disturbance in median nerve dermatome of the hand, and thenar muscle atrophy. Open decompression was a treatment of choice, when operative intervention is necessary. But, endoscopic or percutaneous decompression is introduced recently. Authors analyzed 21 cases of open decompression and 22 cases of percutaneous decompression and they could be follow up over 6 months at Dept. of Orthopedics, Chonnam University Hospital from June 1990 to January 1995. The results are as follows. 1. There were no difference in age, sex, lesion side, symptoms duration until operation, etiology and occupation between percutaneous and open decompression. 2. There were excellent or good results in clinical symptom in 19 cases(90%) of open procedures and 19 cases(86%) of percutaneous procedure and more rapid relief of the pain, and grip power in percutaneous procedure than open procedure. 3. The EMG, recorded at 1 week, 4 weeks, 3 months and 6 months after operation, revealed improvement in sensory than motor function. There was more rapid recovery in percutaneous procedure than open procedure especially latency and amplitude of sensory nerve. There were 2 cases in open procedure and 3 cases in percutaneous procedure who did not respond to treatment. As a result, percutaneous procedure was more simple and rapid recovery than open procedure in clinical progressions and EMG reports, but recovery rate of symptomatic relief was similar. Therefore percutaneous procedure is thought to be more reasonable method in the treatment of carpal tunnel syndrome if surgical intervention is indicated.

Acute mobile thrombus of the abdominal aorta after chemotherapy is a very unusual finding, which can be a potential source of arterial embolism. We report here on a case of an acute mobile aortic thrombus with renal infarction. We successfully treated the patient with hybrid operation-open surgical and endovascular approach. Our case shows that hybrid treatment using wire-directed balloon catheter thrombectomy is a feasible, minimally-invasive treatment for a mobile aortic thrombus.

Recently, surmountable amounts of genes are being cloned without information about them and it has become neccessary to develop new techniques for discovering genes with more informaiion like as chromosomal location and possible functions. We have developed one such a method and applied it to search for genes that may be related with the neural development. The mRNAs were extracted from cerebral cortex of 18 week old human fetus, cDNAs were made by reverse transcription from these mRNAs and Uni-amp cDNAs having Uni-amp adapters at both ends were made for subsequent PCR. To observe the distribution of the Uni-amp cDNAs on the chromosome, fluorescent in situ hybridization was performed with biotin labeled Uni-amp cDNAs. Among the chromosome bands showing strong hybridization with the cDNAs, 7q22 was microdissected from the chromosome hybridized with unlabeled Uni-amp cDNAs and amplified by PCR with Uni-amp primers. These amplified cDNA fragment were subcloned to vectors and the nucleic acid sequences were analysed. As a result, 46 different clones were obtained. They were categorized as 12 clones of well characterized genes, 14 clones showing low homology with known genes, 13 clones of simply registered uncharacterized human cDNAs, 7 clones of unknown genes. In situ hybridization histochemistry of 34 novel genes, except 12 known genes, were performed on developing and adult rat tissue sections to see the tissue specificity and developmental expression of these genes. The expression of several novel genes were restricted to the nervous system. From these results, it may be suggested that our technique is very useful to clone the genes expressed in the developing human braine with confirmed chromosomal location. In addition, this cloning technique can be used to discover the new genes related with neural development in combination with functional screening methods.

In recent years, the interest in minimally invasive surgery has grown, and the same trend is observed in vascular surgery and interventional radiology, leading to what is called endovascular surgery. Since the first use of a stent-graft for the endovascular exclusion of an abdominal aortic aneurysm (AAA), endovascular aneurysm repair (EVAR) has greatly expanded, and more than 50,000 devices have been implanted until now. The endovascular graft can be implanted from a remote access site in the groin with a less anesthetic requirement. The endovascular graft is advanced over guidewires up the femoral and iliac arteries. Once in position, the graft is deployed immediately distal from the renal arteries. The aorta is not clamped and the blood loss is less than with open surgery. EVAR for AAA offers an important new alternative to open surgical procedure. The mortality rates after EVAR are reported between 0~5%. Long-term follow-up reports are not available, but mid-term follow-up of EVAR reveals an incidence of re-intervention between 10~20% and a rate of late rupture of between 0.5~1.5% per year. The problems of endoleaks and graft failure continue to be the challenges that require technological innovations. Based on the currently available evidence, EVAR is an appropriate treatment for selected patients, especially those at high risk for open surgical repair.

Endovascular treatment of isolated bilateral common iliac artery aneurysm (CIAA) requires salvage of at least one internal iliac artery to prevent complications such as ischemic buttock claudication. We treated a case of bilateral CIAAs using an internal iliac branched stent graft. We report a case of a 58-year-old man who presented with bilateral CIAAs. The left internal iliac artery was occluded with coil embolization. The right internal iliac artery was saved by using a branched stent graft. The aneurysms were excluded with conventional endovascular aneurysm repair. Completion angiography showed technical success. Follow up computed tomography angiogram at three months showed complete exclusion of bilateral CIAAs, no endoleaks, and patent right internal iliac artery. There was no pelvic ischemic complication. We treated successfully a case of isolated bilateral CIAAs using an iliac branched stent graft.

Diagnosing pseudoaneurysms of the popliteal artery is usually straightforward in physical examinations and imaging findings. However, when a pseudoaneurysm shows a soft tissue mass with adjacent osseous change, it can mimic a bone tumor or a soft tissue sarcoma. We present a case of a 65-year-old man who had a pseudoaneurysm of the popliteal artery showing soft tissue mass and insinuating into the intramedullary cavity of the tibia. This presented case emphasizes the importance of considering pseudoaneurysms in the differential diagnosis of an apparent soft tissue mass with pressure erosion in adjacent bone.

Percutaneous balloon angioplasty has been reported to be useful in the treatment of intracranial atherosclerotic arterial stenosis. However, arterial dissection with increased risk of acute closure and stroke has limited its widespread implementation. Stenting of the intracranial vasculature recently has been shown to be feasible in a variety of circumstance. However, stenting of middle cerebral artery has been limited because of difficulty with tracking stents across the carotid siphon. We report a case of successful percutaneous stenting of a symptomatic middle cerebral artery stenosis using a balloon-expandible flexible coronary stent.
