Knowledge of variations of veins of head and neck in relation to internal jugular, external jugular, anterior jugular and facial veins is important to surgeons doing head and neck surgery as well as to radiologists doing catheterization and to clinicians in general. In the current case, congenital atresia of the left internal jugular vein is reported. During neck dissection, superficial veins of neck and left external jugular vein was engorged and the left internal jugular vein was look like a fibrotic band. The left common carotid artery and vagus nerve was normal.

To evaluate the effectiveness of central venous catheters(CVCs) in children, 320 CVCs placed in 255 neonate and children over a 10-year period were analyzed retrospectively. CVC was placed by one pediatric surgeon for a total of 6, 116 patients days. Catheters were placed preoperatively for TPN or chemo in 223 cases. CVC was solely for TPN in 57 cases and for chemotherapy in 40. Local anesthesia was utilized in 71 cases, and the general anesthesia was administered in the remainder of the patients. The subclavian vein was catheterized(SCV) in 202 cases(82 infants and neonates), tunneled external jugular venotomy(EJV) was utilized in 38, tunneled internal jugular venotomy(UV) in 2, the facial venotomy(FV) was used in 3, and the umbilical vein was catheterized UVC) with vein transposition in 74 infants. In neonates, 72 UVCs were placed during laparotomy. SCV was increased with ages, from 3 kg of minimal body weight. The average catheter-periods over-all were 19.1 days, SCV 17 days, EJV 40, IJV 60 and UVC 14. Technical complications were; arterial puncture(6), puncture failure(5) and abnormal location(12) in SCV; insertion failure(3) in EJV; abnormal location in the portal vein(4) and the liver parenchyma(2) cystic fluid accumulations in UVC. Twelve migrations(3.8 %) out of position occurred; SCV(2), EJV(1) and UVC(9). There were 4 cases(1.2 %) of catheter obstruction and 11(3.4 %) of catheter infection(3 SCV, 2 EJV and 6 UVC). Rescue procedures were utilized with some success. There was one mortality(0.3 %) due to deep sedation in a 1.06 kg baby during placement of an EJV. The surgeon's experience, proper catheter selection and following safety rules are the most important factors for successful CVCs.

The management of cardiac arrhythmias by cardiac pacing has increased greatly since the treatment of complete heart block with an external transcutaneous pacemaker in 1952, followed by the use of myocardial wires connected to an external pulse generation, by external transvenous pacing, and then by transvenous pacing with implantable components in thoracic wall.By now, the three bases of modern cardiac pacing for bradyarrhythmias had been established [1] an implantable device [2] the transvenous approach [3] the ability of the pacemaker to sense cardiac activity and modify its own function accordingly. In transvenous implantation of a pacemaker, any one of four vessels at the root of the neck is suitable for passage of the electrode - cephalic vein, external jugular vein, internal jugular vein, costo-axillary branch of the axillary vein. The new technique of direct puncture of the subclavian vein, either percutaneously or after skin incision only has been made, is invaluable & is used routinely. We have experienced one 25 years old patient who had rheumatic mitral stenosis & minimum aortic regurgitation with sinus bradycardia associated with premature atrial tachycardia & another 54 years old female patient who was suffered from sick sinus syndrome with sinus bradycardia & sinus arrest. The 1st patient was taken open mitral commissurotomy & aortic valvuloplasty and then was taken atrlal pace-maker implantation through If subclavian puncture method in post-op 14 days, and the second patient was taken atrial pacemaker implantation through If subclavian puncture method. Their postop course was in uneventful & were discharged, without complication. Their condition have been good to now.

Intravenous pyogenic granuloma, commonly known as intravenous lobular capillary hemangioma, is a rare benign tumor of the vein. It rarely occurs in the neck, and its character is not enough to diagnosis clinically. It could be diagnosed with preoperative radiologic examinations such as ultrasound and computed tomography and typical pathologic findings that demonstrate lobules of multiple capillaries lined with flattened endothelial cells admixed with fibromyxoid stroma. The authors report a case of a 32-year-old male who presented with a palpable neck mass for one month with a review of the literature. He was successfully treated with resection, including the tumor and normal external jugular vein, without any complications.

The usefulness of totally implantable central venous port for long-term intravenous infusion is widely accepted in children. Usually the catheters are placed through the internal or external jugular vein. In case of jugular vein cut-down, two separate incisions are needed for catheter and port respectively. Patients also feel uncomfortable as the catheter run through the neck. However these disadvantages can be overcome by using the cephalic vein (CV). We reviewed our experiences on CV cut-down for totally implantable central venous port in children. From January 2002 to December 2006, 201 patients (M:F=127:74) underwent 218 central venous port insertions. Mean age at operation was 5.9 years (2 months - 19 years). Indications included chemotherapy (N=167), long-term intravenous antibiotics infusion (N=36), and total parenteral nutrition (N=15). CV was selected preferentially. The incision includes the deltopectoral triangle laterally, and both the CV cut-down and port insertion were achieved with a single incision. The number of insertion through external, internal jugular vein, and CV was 77, 66 and 75, respectively. The median age, height and body weight were higher in CV cut-down group. The youngest age for CV cut-down was 8 months, the shortest height was 69 cm and the smallest body weight was 5.9 kg. Of 118 trials of CV cut-down, cut-down was successful in 75 cases (63.6 %). CV was absent in 10 cases(8.4 %) and CV was sacrificed after catheter tip malposition in 10 cases (8.4 %). There was only one complication, in which the catheter was inserted into the minute branch of subclavian artery. The CV cut-down method for totally implantable central venous port was safe and feasible in selected groups of patients in children. In addition, preservation of jugular vein and a more favorable cosmetic effect are other benefits of CV cut-down.

Background: To refine facial transplantation techniques and achieve sound results, it is essential to develop a suitable animal model. Rat is a small animal and has many advantages over other animals that have been used as transplantation models. The purpose of this study was to describe a rat hemifacial transplantation model and to verify its convenience and reproducibility. Methods: Animals used in this study were Lewis rats (recipients) and Lewis-Brown Norway rats (donors). Nine transplantations were performed, requiring 18 animals. The hemifacial flap that included the ipsilateral ear was harvested based on the unilateral common carotid artery and external jugular vein and was transferred as a single unit. Cyclosporine A therapy was initiated 24 hours after transplantation and lasted for 2 weeks. Signs of rejection responses were evaluated daily. Results: The mean transplantation time was 1 hour 20 minutes. The anatomy of common carotid artery and external jugular vein was consistent, and the vessel size was appropriate for anastomosis. Six of nine allografts remained good viable without vascular problems at the conclusion of study (postoperative 2 weeks). Conclusion: The rat hemifacial transplantation model is suitable as a standard transplantation training model.

Microvascular anastomosis with suture technique is a basic skill but there are several problems such as stenosis, thrombosis and long operating time. Recently plastic surgeons have developed non-suturing mechanical coupling devices for microvascular anastomosis. The authors applied non-penetrating vascular clips (VCS clips) in the field of free flap surgery of head and neck area. Between August of 2004 and January of 2005, we performed 9 free flaps (16 vessels) using small-sized VCS clips. Four stay sutures were applied first and then VCS clips were placed between sutures about 1 mm apart. Vascular pedicle of free flap included the descending branch of lateral circumflex femoral vessel, thoracodorsal vessel, deep inferior epigastric vessel and cephalic vein. The recipient vessels were the superior thyroid artery, superficial temporal artery, internal jugular vein, external jugular vein, and superficial temporal vein. We performed 13 end-to-end (4 arteries and 9 veins) and 3 venous end-to-side anastomoses. No flap related complication occurred but we applied additional clips or sutures in two cases due to blood leakage after completion of anastomosis. Primary patency rates seemed to be good and more rapid anastomosis could be done than conventional suture technique. Advantages of VCS technique are high patency rate, low thrombogenecity and rapidity. Although the high cost of VCS instrument may be a problem, this clip could be applied safely in microvascular free tissue transfer.

The aim of this study was to investigate the major vascular system to supply flap, flap survival rate and complications after flap elevation in order to evaluate possibility of the vascularized face/scalp allotransplantation. Forty New Zealand white rabbits were divided into two groups: control group and experimental group. Individuals of control group had a face/scalp composite unit which was composed of skin, subcutaneous tissue and platysma muscle, supplying by bilateral facial artery, temporal artery and auricular artery and draining by external jugular vein. After a flap was elevated, bilateral facial artery, temporal artery and auricular artery were ligated. On the other hand, those of experimental group had the same composite unit as control group with bilateral facial artery, temporal artery and auricular artery being not ligated. We had measured survival area of flaps of the sixteen individuals survived for four weeks in the control group and fourteen in the experimental group by Grid method. The mean survival durations of the flap were 3.7days in the control group, 20.0days in the experimental group. The significant differences in the mean survival durations and survival rate at the 28days were found between the control and experimental group (p<0.05). Mean values about the survival area's fractions of all were $1.3{\pm}4.%$ in the control group and $63.1{\pm}4.8%$ in the experimental group. Those of experimental group was significantly higher than control group statistically (p<0.05). The composite face/scalp flap which we have elevated, supplied by bilateral facial artery, temporal artery, auricular artery and drained by external jugular vein has flap viability enough to be transplanted after its elevation.

Since cardiac pacemaker was first totally implanted by Chardack, Gage and Greatbatch [1966], the electrical circuity of the cardiac pacemaker has been improved, modified, and refined. The problem of transvenous electrodes, however, is still remained; this may be due to electrode displacement, exit and/or entrance block, lead fracture and insulation defects. In permanent cardiac pacing, Irreversible loss of function of the transvenous electrode catheter eventually requires insertion of new lead. Authors now report one case that disclosed easy displacement of electrode tip in early phase of implantation and then two years and five months later, malfunctioning electrode could not be withdrawn from the cardiovascular system because it has become firmly enclosed by fibrous tissue along its course from the vein tract to the right ventricle. Under such circumstances, the electrode catheter tip was left in tricuspid annulus after being sutured at its entrance and burying the loop of lead in generator pocket. New other one electrode was then reimplantation through left external jugular vein.
