We report a case of digital mucous cyst with longitudinal groovings of the nail distal to the cyst which was treated by multiple puncture method described by other authors. The digital mucous cyst was cured without any sequelae and no recurrence has developed within 2 years. Also the nail groovings returned to normal.

Although epidural block is a well-established anesthetic method, we often experience a failed epidural block. The success rate of epidural block is dependent on the accurate identification of the epidural space and successful location of the catheter within the epidural space. Rarely, it is missed to identify the epidural space with a loss of resistance method due to a variable anatomy of the epidural structure. Occasionally, an epidural catheter may pass into the extra-epidural space. We report 2 cases of misplacement of an epidural catheter in the extra-epidural space. These cases highlights the need for careful identification of the epidural space during epidural puncture and confirming the location for successful placement of the catheter within the epidural space by using a test block with a test dose of the local anesthetic drug after epidural catheterization.

BACKGROUND: Many factors affecting the spread of spinal anesthesia have been investigated. But L3-4 or L4-5 interspace was choosen which was known as the site of buffering, in their study. We investigated the effect of some of these factors on sensory blockade level by using L2-3 interspace. METHODS: Eightyfive patients, ASA physical status I - Il, were involved in our study. Sensory blockade level was checked with pinprick test at 10 minutes and 30 minutes. The effect of age, sex, height, weight, CSF pressure and pressure difference generated when full flexed and non-full flexed lateral position on sensory blockade level was studied whereas other factors such as puncture technique, dosage and concentration of drug and patients position after injection, were kept constant under the same condition. And also studied the effect of degree of flexion at injection on the sensory blockade level. RESULTS: Height and CSF pressure were correlated with sensory blockade level at 10 minutes after injection(R2=0.14, P<0.01). Only height was correlated with sensory blockade level at 30 minutes after injection(R2=0.09, P<0.0l). CONCLUSIONS: Only height was correlated with sensory blokade level at 30 minutes. So, height might be considered as the most impressive minor factor affecting the extent of sensory blockade level.

The antegrade puncture technique represents a new approach to percutaneous transhepatic cholangiography andbiliary drainage. With this technique, ductal puncture begins with the liver capsule toward the hepaticparenchyma. This report briefly describes this new technique, and its safety and feasibility.

PURPOSE: To evaluate the performance of a newly-designed ultrasound (US)-guided puncture device. MATERIALS AND METHODS: A newly-designed US-guided puncture device was composed of a guide segment and an attachable segment. The guide segment allowed the needle to be placed in the plane of US view with a maximal degree of freedom, and the attachable segment was designed to attach to most convex US probes. Six operators punctured 144 targets in phantoms using either the new device (n = 72) or free-hand technique (n = 72). The number of required needle passages and the necessary procedure times were compared between the two groups. RESULTS: The number of required needle passages and the necessary procedure time were significantly reduced in five operators when the newly-designed US-guided puncture device was used (p < 0.05). CONCLUSION: A newly-designed US-guided puncture device, which allows for a maximal degree of freedom in needle placement and can attach to most convex US probes, showed good performance in our study.

Cricothyroid membrane puncture and incision,the key techniques to save the lives of the patients in the Can't Intubate,Can't Oxygenate (CICO) emergency,need to be mastered by all the airway management staff.However,the decision to carry out cricothyroid membrane puncture or incision is often delayed due to the unfamiliarity with the adjacent anatomical structure of the cricothyroid membrane and the inability to accurately locate the cricothyroid membrane.As a result,serious complications and rescue failure occur.Therefore,airway management staff should be familiar with the adjacent structure and positioning methods of the cricothyroid membrane,so as to improve the success rate of emergency airway rescue,reduce complications,and protect the airway and life safety of the patients.

In the management of postoperative fluid collection, the conventional percutaneous drainage method can be employed. Because of abdominal incisions and various types of surgical drains and/or T-tubes, the application of this method is not always easy, however. We inserted a drainage catheter through a pre-existing percutaneous track formed by a surgical drain located adjacent to the site of abnormal fluid collection. There was no need to remove the drain nor make an additional puncture in the abdominal wall. A dilator was inserted along the drain, and a guide wire was used to negotiate its intraperitoneal track and readch the accumulated fluid. The procedure was simple and safe. We briefly deseribe our experience of this modified percutaneous drainage technique, as used in three cases involving postoperative fluid collection.

Mandibular arteriovenous malformations(AVM) are relatively rare and potentially life threatening lesions. Surgical treatment consists of wide resection of the mandible, which is difficult and potentially hazardous due to significant blood loss during surgery. Therefore, some authors advocate that transvenous embolization may be a safer and more effective method in the treatment of mandibular AVM. We report a treatment case of mandibular AVM in a 9-year-old-girl for episodes of spontaneous bleeding for 6 days using by selective transarterial embolization ,direct puncture embolization and microcoil embolization.
