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.

The 25 healthy male volunteers aged from 20 to 50years old have been employed in this study. 2D-PC MRA was performed to measure the velocity of the blood flow in the internal carotid artery and internal jugular veins using 3.0T MRI Whole body (signa VH/i GE). ECTRICKS-CEMRA was performed to evaluate the pattern of blood circulation from internal carotid artery to internal jugular vein. Using 2D-PC MRA, the cross-section of the 4th and 5th cervical discs was scanned with 24cm FOV. Then the speed of blood flow was measured for internal carotid artery and internal jugular vein when the subject wears a necktie tightly and no tie. The average of maximum velocity of internal carotid arteries without a necktie was 72.13cm/sec in the right side and 74.96cm/sec in the left side(average 73.54cm/sec in both sides) while the average of maximum velocity of internal jugular veins without a necktie was -34.45cm/sec in the right side and -24.99cm/sec in the left side (-29.72cm/sec in both sides). However, when wearing a necktie tightly, the average of maximum velocity of internal carotid arteries was 61.35cm/sec in the right side and 65.19cm/sec in the left side(average 63.27cm/sec in both sides) while the average of maximum velocity of internal jugular veins was -22.14cm/sec in the right side and -17.93cm/sec in the left side(-20.03cm/sec in both sides). With the necktie tightly knotted, the average blood flow speed of both internal carotid arteries slightly decreased to 86% (63.27/73.54cm/sec) compared to no tie case in which both internal jugularveins significantly went down to 67% (-20.03/-29.72 cm/sec). Thus it is suggested that wearing a necktie affects the circulation of internal jugular veins(33% decrease in blood flow speed) more significantly than that of internal carotid artery(14% decrease in blood flow speed). Without a necktie, ECTRICKS-CEMRA showed natural blood circulation patterns of internal carotid arteries and internal jugular veins without any disturbances or compressions. However, when wearing a necktie tightly, ECTRICKS-CEMRA showed severe compression onto both internal jugular veins in all 25 volunteers. In conclusion, the result of the study showed that the tightly worn necktie instantly presses more internal jugular veins than internal carotid arteries, thereby significantly reducing the blood flow speed and leading to the temporary occlusion. Thus, the defecation or washing the face under the tightly tied necktie situations can cause the unexpected and temporary compression or occlusion of the internal jugular veins, subsequently leading to the occurrences of the stroke due to the secondary intracranial venous hypertension.

Jugular bulb diverticulum is an irregular extension of the jugular bulb into the temporal bone that may be symptomatic or asymptomatic. The jugular bulb has rarely been reported to extend into the occipital condyle; such extension is termed a condylar jugular diverticulum and is characterized as a defect in the occipital condyle contiguous with the jugular bulb. This report details 3 cases of condylar jugular diverticulum. Extension of the jugular bulb into the ipsilateral occipital condyle was noted as an incidental finding on cone-beam computed tomographic (CBCT) images of 3 patients. All 3 patients were asymptomatic, and this finding was unrelated to the initial area of interest. CBCT use is becoming ubiquitous in dentistry, as it allows 3-dimensional evaluation, unlike conventional radiography. Proper interpretation of the entire CBCT is essential, and recognition of the indicators of condylar jugular diverticulum may prevent misdiagnosis of this rare entity.

The blood components of not-young (young antler) were examined in the Red Deer. Blood samples were collected from the antler and jugular veins respectively. The hematological and serum chemical values were as follows; 1. RBC count of not-hyul (young antler blood) was significantly higher than that of jugular vein blood (p<0.05). However, fibrinogen concentration of rook hyul was significantly lower than that of jugular vein blood (p<0.01). WBC counts packed cell volume (PCV) and total protein fro) were not significant between nolo-hyul and jugular vein blood. 2. The concentration of phosphorous and magnesium of not-hyul were significantly higher than those of jugular vein blood (p<0.05). Albumin and glutamic oxaloacetic transaminase (GOT) of nolo-hyul were higher than those of jugular vein blood. But globulin and calcium concentration of not-hyul were lower than those of jugular vein blood. Blood urea nitrogen BUN) of rook-hyul was not significant when compared with that of jugular vein blood.

Serum biochemical values were measured in blood samples collected from 8 fasted stags from both jugular and femoral veins at 18-day intervals during antler growth. Samples were analyzed for blood substrate, enzyme activity values, minerals and electrolyte. There were no significant differences in total protein, albumin, urea, creatinine, triglyceride, glucose or cholesterol concentration between veins or sampling dates. However, total-bilirubin concentration in the jugular vein on the casting date was three times higher than on the other sampling dates (p<0.05). There were no significant differences in alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase with progressing antler growth. The highest level of alkaline phosphatase concentration was on day 55 after casting. There were no significant differences in inorganic phosphorus, sodium and chloride concentration between jugular and femoral samples. Calcium concentration was significantly higher in the femoral vein on the cutting date (55 day) than in the jugular vein (p<0.05). There were few changes in serum biochemical values. However, some electrolytes and minerals had differences during antler growth. It is suggested that despite such a big event as antler growth, blood biochemical values are not variable if feeding conditions are consistently maintained as was the case in this study.

Lemierre syndrome is caused by acute oropharyngeal infections with secondary septic thrombophlebitis of the internal jugular vein and is characterized by frequent metastatic infections. A 56-year-old man presented with severe reddish inflammatory swelling of the right cervical soft tissue. Thrombophlebitis in the right internal jugular vein and multiple pulmonary embolisms were identified on neck and chest computed tomography (CT). He was treated with antibiotics and heparin for 4 weeks and then discharged without other complications.

Lamierre's syndrome is characterized by a rare fulminant condition resulting from primary oropharyngeal infection followed by secondary septic thrombophlebitis of the internal jugular vein and metastatic infection. A forty-year-old man who had been on ventilator due to servere chest trauma, showed severe reddish inflammatory swelling of the right cervical soft tissue and newly developed pneumonia. He went into in septic condition shortly thereafter. Thrombophlebitis with central abscess in the right internal jugular vein was identified by neck CT and MRA(magnetic resonance angiography). Right cervical swelling worsened in spite of clindamycin and heparin therapy. We performed immediate surgery for removal of septic thrombus and resection of internal jugular vein. Patient's septic condition, pneumonia, and local inflammatory reaction were improved within several days after surgery.

A 48-year-old female complained of edema and pain in her left neck. She underwent acupuncture therapy for 1 month in a local oriental medicine clinic because of her arm pain. Computer tomography showed left internal jugular vein thrombosis. The patient's condition improved after antibiotic medication and anticoagulation. The patient is currently in outpatient department follow-up and doing well. To the best of our knowledge, this is the first report of an internal jugular vein thrombosis secondary to acupuncture.

We report the case of a 64-year-old man with dural arteriovenous fistula (DAVF) at right jugular foramen, presented as subarachnoid and intraventricular hemorrhage. The malformation was fed by only the neuromeningeal trunk of the right ascending pharyngeal artery and drained into the right lateral medullary veins craniopetally. Complete embolization was attained by selective transarterial glue injection, but patient showed lower cranial neuropathies. A 3-month follow-up angiogram still showed persistent fistula occlusion. Transarterial glue embolization is a feasible method, only if a transvenous access is not possible in case of single channel fistula.

Fungal thrombophlebitis of the central vein is a rare, life-threatening disease associated with significant morbidity and mortality. It requires immediate central venous catheter removal and intravenous antifungal therapy, combined in some cases with either anticoagulation or aggressive surgical debridement. A 70-year-old male patient injured by a falling object weighing 1,000 kg was transferred to our hospital. A contained rupture of the abdominal aorta with retroperitoneal hematoma was treated with primary aortic repair, and a small bowel perforation with mesenteric laceration was treated with resection and anastomosis. After a computed tomography scan, the patient was diagnosed with thrombophlebitis of the left internal jugular vein and brachiocephalic vein. Despite antifungal treatment, fever and candidemia persisted. Therefore, emergency debridement and thrombectomy were performed. After the operation, the patient was treated with an oral antifungal agent and direct oral anticoagulants. During a 1-year follow-up, no signs of candidemia relapse were observed. There is no optimal timing of surgical treatment for relapsed fungal central thrombophlebitis. Surgical treatment should be considered for early recovery.
