The fashion of vascular anastomosis, end-to-end or end-to-side (E-to-S), are depended upon surgeon's preference or surgical situations. In E-to-S anastomosis two different methods of arteriotomy are applicable but it has been suggested the type, either elliptical or slit arteriotomy, play a different role in the flow hemodynamics. We thought that the difference is more considerable in microvascular surgery. This study examines the effects of elliptical versus slit arteriotomy on morphologic vessel patency. Twenty male Sprague-Dawley rats were divided into two groups of ten rats each. Both carotid arteries were selected as a experimental model. During the procedures the rat brain was tolerable to ischemia and all animals were survived after operations. The morphologic analysis of anastomosis site was through resin-casting method with scanning electromicroscopic examination. The results showed notable difference between two groups in three-dimensional morphology at two-month of operation. This difference may affect the flow hemodynamics and long-term vessel patency. In microvascular anastomosis, the mortpologic difference of the elliptical arteriotomy is worse than slit arteriotomy which compromises the vessel circumference.

The nerve root block or selective nerve root block is one of the primarily preoperative diagnostic tool to identify and confirm the lesion site of primary cause of pain and that is considered as one component of a comprehensive treatment program. The purpose of our study is to evaluate the effect and duration of the pain control by selective spinal nerve root block as a conservative treatment in patients presenting with chronic or recurrent sciatica. The authors performed 95 selective nerve root blocks in 72 patients from Sep. 1994 to May. 1996, (mean follow up 11.6 month) at the department of orthopedic surgery, Kosin University Gospel Hospital, and the results were as follows: 1. Among 72 cases, spinal stenosis was in 45 cases (62.5%), HIVD in 19 cases (26.4%), failed back syndrome in 5 cases (6.9%), spondylosis in 2 cases (2.8%), and spondylolisthesis in I case (1.4%). 2. In 72 cases, improved more than 50% of sciatica were 61 cases (84.7%) at 3 hours, 53 cases (73.6%) at I week, 35 cases (48.6%) at 1 month, 33 cases (45.8%) at 3 months, and 33 cases (45.8%) at 6 months respectively. 3. At last follow-up, excellent and good results were 35 cases (48.6%), fair results were 25 cases (34.7%) and poor results were 12 cases (16.7%) by the Kirkaldy-Willis criteria. 4. Complications were 1 case of transient hypotension, 2 cases of severe paresthesia, but subsided without residual complication. Therefore, the selective nerve root block is one of the valuable procedure that is helpful and extremely safe in useful treatment for radicular pain associated with lumbar disease. And the trial of selective nerve root block was recommended before deciding surgical intervention on an outpatient basis.

We report herein a case of desmoplastic trichoepithelioma in a 73-year-old female, who is the oldest among the patients of the disease reported in Korea. She had an asymptomatic, hard, annular lesion, measuring 0.6 x 0.7 cm with an elevated border and a depressed center on the left nasolsbial fold. Histopathological findings showed narrow strands of basaloid tumor cells, horn cysts and a desmoplastic stroma.

We present a case of acquired tracheoesophageal fistula (TEF) which was found during induction of general anesthesia for clipping of aneurysm. The patient had been intubated with endotracheal tube for 10 days and then done tracheotomy for 45 days. Thereafter, TEF was confirmed by MRI and treated with fistula repair and tracheal fenestration. Acquired TEF can occur under the condition of prolonged tracheal intubation with high cuff pressure (>30 mmHg) and can also result from intratracheal neoplasm, mediastinitis, and other tracheal or esophageal damages. If unrecognized during anesthetic induction, TEF can cause gastric dilatation and rupture, pulmonary aspiration and respiratory failure. So early diagnosis and proper management is very important whenever TEF is suspected during anesthetic induction.
