Purpose: The purpose was to identify quality of chest pain according to causal diseases and pain expression of patients with coronary artery diseases. Method: Participants were 1,964 patients with pain who visited the emergency department of A hospital from January to December 2006. Data were collected from nurses' and doctors' records as to causal disease, and quality and expression of chest pain. Results: Causal diseases were coronary artery diseases, non-specific chest pain, respiratory diseases, non-coronary artery heart diseases and digestive diseases in that order of frequency. Every disease except respiratory disease caused mostly dull and tract pain, but 63.7% of patients with coronary artery diseases complained of typical angina pain and 24.9% complained of atypical angina pain. Patients with coronary artery diseases mostly used word 'heaviness' in describing their dull pain, and 'squeezing' for tract pain. Both male and female patients who were diagnosed with coronary artery disease complained mostly frequently of dull pain and tract pain. Conclusion: The most common causal disease for patients with chest pain was coronary artery disease. Patients with other diseases also frequently complained of dull and tract pain, the same as patients with coronary artery diseases. A considerable number of patients complained various types of atypical angina pain in coronary artery diseases.

An aberrant left hepatic artery is one of the most common variants of hepatic arteries, and its prevalence has been reported 6.5-30%. During D2 lymph node dissection for gastric cancer, an aberrant left hepatic artery arising from left gastric artery is ligated which may lead to hepatic damage. In this case report, a 66-year-old male patient underwent total gastrectomy with D2 lymph node dissection during which the aberrant left hepatic artery was ligated. Post-operative liver function tests revealed elevated liver enzymes, and ischemic changes in the left lateral hepatic section was seen on the CT scan. On retrospective review of preoperative CT images, a replaced left hepatic artery from left gastric artery could have been identified. The information on the presence of aberrant LHA and its supplying area is clinically important when planning curative gastrectomy for gastric cancer, because extended lymph node dissection requires division of the left gastric artery and this may lead to severe liver damage. By using preoperative CT scan, detection of aberrant left hepatic artery could be done.

Despite several studies focusing on the facial arteries variable courses, the findings have significantly differed. The divergent findings have made it increasingly challenging to establish consistent correlations. Thus, as a vital artery, the facial artery is prone to numerous variations, which makes the identification of the variations vital to clinical practice, particularly for the orofacial and rhinoplastic surgery, and the increasingly selective chemotherapy procedures. The present research uses angiography images for analysis in studying the bilateral facial artery variations noted in patients undergoing carotid angiography for the evaluation of congenital anomalies, cerebral vascular malformations, and intra-arterial procedures. Conventional angiography was used, as it is a vital assessment tool that helps in the assessment of variations in the facial arteries and is suitable in evaluating smaller vascular anatomy, due to the perfect spatial resolution and portrayal of vascular anatomy. Thus, rather than normal ending of the facial artery as an angular artery, the study disclosed that in certain instances, the artery termination took the form of a superior labial artery with a small lateral nasal artery branch located closer to the midline compared to the normal cases. Also, the study has disclosed a conspicuous pre-masseteric branch with small branches originating from the infraorbital artery and providing potential compensation for the facial artery's shortness. Regardless of the infrequency of such variations, it is vital that they are considered during the performance of any facial surgical procedure.

The absence of the common carotid artery (CCA) and the common origin of the left external carotid artery (ECA) and the right CCA are rare anomalies of the cervical vascular system. We report here a case involving the coexistence of these vascular anomalies with an aberrant right subclavian artery, which is a common congenital anomaly in the aortic arch, and review the embryologic mechanism and clinical importance of this case.

Background: The facial artery is an important blood vessel responsible for supplying the anterior face. Understanding the branching patterns of the facial artery plays a crucial role in various medical specialties such as plastic surgery, dermatology, and oncology. This knowledge contributes to improving the success rate of facial reconstruction and aesthetic procedures. However, debate continues regarding the classification of facial artery branching patterns in the existing literature. Methods: We conducted a comprehensive anatomical study, in which we dissected 102 facial arteries from 52 embalmed and formaldehyde-fixed Vietnamese cadavers at the Anatomy Department, University of Medicine and Pharmacy, Ho Chi Minh City, Vietnam. Results: Our investigation revealed eight distinct termination points and identified 35 combinations of branching patterns, including seven arterial branching patterns. These termination points included the inferior labial artery, superior labial artery, inferior alar artery, lateral nasal artery, angular artery typical, angular artery running along the lower border of the orbicularis oculi muscle, forehead branch, duplex, and short course (hypoplastic). Notably, the branching patterns of the facial artery displayed marked asymmetry between the left and right sides within the same cadaver. Conclusion: The considerable variation observed in the branching pattern and termination points of the facial artery makes it challenging to establish a definitive classification system for this vessel. Therefore, it is imperative to develop an anatomical map summarizing the major measurements and geometric features of the facial artery. Surgeons and medical professionals involved in facial surgery and procedures must consider the detailed anatomy and relative positioning of the facial artery to minimize the risk of unexpected complications.

Purpose: Liver transplantation is considered as the treatment of choice in many acute and chronic liver diseases, and it is becoming more common. Since successful microscopic anastomosis of hepatic artery is a crucial requirement of successful liver transplantation, we studied and analyzed the result of hepatic artery anastomosis of liver transplantation in our liver transplantation center. Methods: 145 liver transplantations were performed between February 2005 and May 2008. Male to female ratio of the liver transplantation recipients was 3.4 : 1. Anastomosis of portal vein, hepatic vein and biliary tract was performed by the general surgeon, and anastomosis of hepatic artery was performed by the plastic surgeon under the loupe or microscopic vision. After the hepatic artery was reconstructed, anastomosed site status and flow were checked with Doppler ultrasonography intraoperatively and with contrast enhanced CT or angiography postoperatively if necessary. Results: Out of 145 liver transplantations, cadaveric liver donor was used 37 cases and living donor liver transplantation was performed 108 cases including the 2 dual donor liver transplantations. As for the baseline diseases that resulted in the liver transplantation, there were 57 cases of liver cirrhosis and hepatocellular carcinoma due to hepatitis B, taking up the greatest proportion. Single donor hepatic artery was used in 114 cases, and mean artery diameter was 2.92 mm and mean artery length was 24.25 mm. Hepatic artery was used as the recipient artery in every case except the 8 cases in which gastroepiploic artery was used as alternative. Out of 145 cases of hepatic artery anastomosis, 3 cases resulted in the thrombosis of the hepatic artery, requiring thrombectomy and re - anastomosis. In all 3 cases, thrombosis was found in left hepatic artery and there was no past history of hepatic artery chemoembolization. Conclusion: Incidence of hepatic artery thrombosis after the anastomosis of hepatic artery during liver transplantation was 2.1%, which is considered sufficiently low.

Objective : The aim of this study was to evaluate the utility of volume-rendered helical computerized tomography (CT) angiography focusing tracheostomy tube and innominate artery for prevention of tracheoinnominate artery fistula. Methods : The authors retrospectively analyzed 22 patients with tracheostomy who had checked CT angiography. To evaluate the relationship between tracheostomy tube and innominate artery, we divided into three categories. First proximal tube position based on cervical vertebra, named "tracheostomy tube departure level (TTDL)". Second, distal tube position and course of innominate artery, named "tracheostomy tube-innominate artery configuration (TTIC)". Third, the gap between the tube and innominate artery, named "tracheostomy tube to innominate artery gap (TTIG)". The TTDL/TTIC and TTIG are based on 3-dimensional (3D) reconstruction around tracheostomy and enhanced axial slices of upper chest, respectively. Results : First, mean TTDL was $6.8{\pm}0.6$. Five cases (23%) were lower than C7 vertebra. Second, TTIC were remote to innominate artery (2 cases; 9.1 %), matched with it (14 cases; 63.6%) or crossed it (6 cases; 27.3%). Only 9% of cases were definitely free from innominate artery injury. Third, average TTIG was $4.3{\pm}4.6$ mm. Surprisingly, in 6 cases (27.3%), innominate artery, trachea wall and tracheostomy tube were tightly attached all together, thus have much higher probability of erosion. Conclusion : If low TTDL, match or crossing type TTIC with reverse-L shaped innominate artery, small trachea and thin TTIG are accompanied all together, we may seriously consider early plugging and tube removal.

Purpose : Stroke is one of the leading causes of death in Korea. Atherosclerotic disease in the carotid artery bifurcation is the most common cause of stroke. The carotid artery calcification is easily appreciated by CT (Computed tomography). CT is often taken in a dental hospital for the diagnosis of inflammation, injury, cyst or tumor on maxillofacial region. However, there was no report of carotid artery calcification on CT in dental patients. This study was to determine the prevalence of carotid artery calcification on CT in dental patients. Materials and Methods : The presence of carotid artery calcification was evaluated by an experienced radiologist on CT scans of 287 patients (166 males, 121 females, average age 42, range 6 to 86 years) and the medical history of the patient and the interpretation of CT were reviewed. Results : Carotid artery calcification was detected on CT scans of 57 patients (19.8%; 35 males, 22 females). All the male patients with carotid artery calcification were older than 50, and all the female patients with carotid artery calcification were older than 60. Among the 57 patients, 10 had Diabetes mellitus, 20 had cardiovascular disease, 3 had history of stroke and 3 underwent radiation therapy for head and neck cancer. Carotid artery calcification was not included in the interpretation of CT of dental patients except one patient. Conclusion : The prevalence of carotid artery calcification on CT of dental patients was about 20% in this study. Carotid artery calcification should be included in the interpretation of CT of dental patients.

A coronary arteriovenous fistula represents an abnormal communication from a coronary artery that may enter any cardiac chamber, a pulmonary artery, the coronary sinus, the superior vena cava or the pulmonary vein. We had a successful experience with 46 year-old male who complained exertional dyspnea[NYHA classification II] and anginal pain since 5 years ago. In intensive study of cardiac catheterization and coronary cineangiography, multiple bilateral coronary arteriovenous fistulas and mitral stenoinsufficiency with left atrial thrombi were recognized. The coronary arterio-venous fistula of left coronary artery was revealed large tortuous aberrant vessels that were connected between just distal portion of first diagonal branch of left anterior descending artery and main pulmonary artery. Other fistula was small tortuous vessel which was originated from left atrial branch of left circumflex artery, was drained into left atrium. The fistula of right coronary artery was communicated conal branch of right coronary artery to main pulmonary artery. But there was no 0y step-up in the right cardiac catheterization. The operative procedure were suture-ligation of draining orifice of coronary arteriovenous fistula in main pulmonary artery, mitral valve replacement[Ionescu-Shiley 25mm] with removal of left atrial thrombi and plication of left atrium under the extracorporeal circulation. The postoperative course was uneventful without any complication and discharged without problem at 17th postoperative days.
