Purpose: Continuous intravenous access is imperative in emergency situations. Ultrasound-guided internal jugular vein (IJV) catheterization was investigated in critically ill pediatric patients to assess the feasibility of the procedure. Methods: Patients admitted to the pediatric intensive care unit between February 2011 and September 2012 were enrolled in this study. All patients received a central venous catheter from attending house staff under ultrasound guidance. Outcome measures included successful insertion of the catheter, cannulation time, number of cannulation attempts, and number and type of resulting complications. Results: Forty-one central venous catheters (93.2%) were successfully inserted into 44 patients (21 males and 23 females; mean age, $6.54{\pm}1.06$ years). Thirty-three patients (75.0%) had neurological disorders. The right IJV was used for catheter insertion in 34 cases (82.9%). The mean number of cannulation attempts and the mean cannulation time was $1.57{\pm}0.34$ and $14.07{\pm}1.91$ minutes, respectively, the mean catheter dwell time was $14.73{\pm}2.5$ days. Accidental catheter removal was observed in 9 patients (22.0%). Six patients (13.6%) reported complications, the most serious being catheter-related sepsis, which affected 1 patient (2.3%). Other complications included 2 reported cases of catheter malposition (4.6%), and 1 case each of arterial puncture (2.3%), pneumothorax (2.3%), and skin infection (2.3%). Conclusion: The results suggest that ultrasound-guided IJV catheterization can be performed easily and without any serious complications in pediatric patients, even when performed by visiting house staff. Therefore, ultrasound-guided IJV catheterization is strongly recommended for critically ill pediatric patients.

Seventeen cases of vascular injuries treated in Chungnam National University Hospital during the period from Apr. 1980 to Sep. 1988 were reviewed. Common causes of injuries were stab wound, automobile accidents and iatrogenic injuries. Of the 11 arterial injuries, 3 were femoral artery which was the commonest in frequency, the next was 2 cases of subclavian, common carotid, iliac artery. Of the 10 venous injuries, the subclavian vein and internal jugular vein were common in frequency. The most frequent type of injuries was laceration[13 cases in 21]. Vascular reconstruction was done by lateral suture repair in 8 cases, autogenous vein graft in 2, prosthetic vascular graft in 5, direct anastomosis in 1 case. Simple ligation was done in 5 cases. There was 1 case of visual field defect as a sequelae in right common carotid artery transaction and 1 case of mortality.

Epithelioid hemangioendothelioma (EHE) is a relatively rare and moderately aggressive type of vascular tumor. We describe a case of EHE that presented in a 24-year-old woman as a palpable nodule in the left cervical area. Radiological examinations and fine-needle aspiration cytology led to a preliminary diagnosis of metastatic lymphadenopathy with an unknown primary site. However, during surgery, we determined that the nodule was an intra-vascular tumor arising from the left internal jugular vein. The histopathological examination revealed cords of epithelioid endothelial cells distributed in a hyaline stroma, compatible with a diagnosis of EHE.

Penetrating neck trauma by gunshot injury involving tracheobronchial tree is rare in Korea. Extensive tissue damage by cavitation, tissue fragmentation and shock wave transmission of high-velocity projectile along with associated organ injury renders high rate of mortality and morbidity. A 28 year old man in military service with gunshot wound in left cervical area presented initial symptoms of severe dyspnea and subcutaneous emphysema. Computed tomography of chest and cervical region as well as bronchoscopic evaluation was performed to confirm highly suspected injury to cervical trachea. Surgical exposure was established through a low collar incision; the damaged segment of 3.5 cm length including 2-4th tracheal rings was resected out and end-to-end anastomosis was performed. Bleeding from lacerated anterior jugular vein was controlled by ligation of both ends and a K2 bulllet was found upon inner border of body of first rib, medial to right carotid sheath and removed out. Cervical esophagus, carotid artery, internal jugular vein and recurrent laryngeal nerve were spared. Extubation was done on the first postoperative day and postoperative course until discharge on nineth postoperative day remained uneventful.

목적: 조영 증강 삼차원 자기공명혈관촬영술에서 관찰되는 내경정맥 폐쇄의 원인을 조영 증강 전산화단층촬영술을 이용하여 분석하고자 한다. 대상과 방법: 2005년부터 2008년까지 두경부 조영증강 자기공명혈관조영술과 조영증강 전산화단층촬영술을 함께 시행한 30명의 환자를 대상으로 하였다. 조영증강 자기공명혈관조영술에서 내경정맥의 폐쇄가 있는 경우 폐쇄군으로 하였고 내경정맥의 폐쇄가 없는 경우 대조군으로 구분하였다. 다음의 지표를 조영증강 전산화단층촬영술에서 분석하였다 : 1) 내정정맥의 직경; 2) 경상돌기와제일경추의 외측돌기와의 거리; 3) 제일경추의 외측돌기의 최대넓이 이후 각각의 지표를 폐쇄군과 대조군에서 비교하였다. 결과: 폐쇄군에서 내경정맥의 직경 그리고 정상돌기와 제일경추의 외측돌기와의 거리는 각각 $1.6{\pm}1.0\;mm$ 그리고 $4.1{\pm}2.1\;mm$로 평가되었으며 이는 대조군과 비교하여 유의하게 작게 분석되었다 (p < 0.01). 폐쇄군에서 제일경추의 외측돌기의 최대 넓이는 $103.4{\pm}25.3\;mm^2$로 평가되었으며 이는 대조군과 비교하여 유의하게 넓은 것으로 나타났다 (p < 0.05). 결론: 조영증강 자기공명혈관촬영술에서 보이던 대경정맥 폐쇄의 원인은 제일경추의 비대칭적인 큰 넓이에 의한 것 일수 있다.

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.

경동맥과 경정맥 사이의 외상성 동정맥루는 매우 드문 질환이고 경부의 해부학적 복잡성으로 인해 외상 후 진단을 놓치는 경우가 있으므로 혈관 손상이 있는 경우에는 동정맥루의 발견을 위해 적극적인 검사가 필요하다. 44년 전에 경부에 총상을 입은 57세 남자에서 늦게 발견된 경동맥-경정맥간의 동정맥루를 치험하였기에 보고하는 바이다.

Lemierre 증후군은 급성 입인두 감염의 합병증으로 생기는 질환으로, 이차적인 혈전 정맥염과 여러 장기를 침범하는 전이성 색전이 특징이다. 1940년대 이후 항생제가 도입되면서 "잊혀진" 질환이었지만, 영상의학 검사가 발달하면서 Lemierre 증후군의 보고가 많아지고 있다. 건강한 16세 남자 환자가 입인두 감염 후에 5일간 지속된 발열과 경부 강직으로 응급실에 내원하였다. 입원 초기에는 뇌수막염에 준하여 치료를 시작하였으나 추후 경부 전산화 단층촬영에서 오른쪽 속목정맥 안의 혈전이 발견되어 Lemierre 증후군으로 진단하였다. 환자는 입원 2일째 갑자기 복시를 호소하였으나 곧 증상이 호전되었으며, 그 외 전이성 색전에 의한 증상은 발견되지 않았다. 총 3주간의 항생제 치료 후 정맥 내 혈전이 소실된 것을 경부 초음파로 확인하고 치료를 종료하였다.

Background: The advance in microsurgical technique has facilitated a proper approach for reconstruction of extensive head and neck defects. For the success of free tissue reconstruction, selection of the recipient vessel is one of the most important factors. However, the vascular anatomy of this region is very complex, and a clear guideline about this subject is still lacking. In this study, we present our 30 years of experiences of free tissue reconstruction for head and neck defects. Methods: In this retrospective study, we analyzed a total of 138 flaps in 127 patients who underwent head and neck reconstruction using free tissue transfer following tumor resection between October 1986 to August 2019. Patients who underwent facial palsy reconstruction were excluded. Medical records including patient's demographics, detailed operation notes, follow-up records, and photographs were collected and analyzed. Results: Among a total of 127 patients, 10 patients underwent a secondary operation due to cancer recurrence. The most commonly used type of flap was radial forearm flap (n=107), followed by the anterolateral thigh flap (n=18) and fibula flap (n=10). With regard to recipient vessels, superior thyroid artery was most commonly used in arterial anastomosis (58.7%), and internal jugular vein (51.3%) was the first choice for venous anastomosis. The flap survival rate was 100%. Four cases of venous thrombosis were resolved with thrombectomy and re-anastomosis. Conclusion: Superior thyroid artery and internal jugular vein were reliable choices as recipient vessels. Proper recipient vessel selection could improve the result of head and neck reconstruction.
