BACKGROUND: Arterial injury surrounding the mandibular angle is very common during mandibular angle ostectomy. The retromandibular vein is susceptible to injury owing to thin vascular wall and deep location. Anatomical studies regarding the retromandibular vein are rarely reported.OBJECTIVE: To observe the construction, branches, backstreaming of the retromandibular vein and its relation to the facial nerve and mandibular angle.METHODS: Twenty formalin-fixed adult cadavers (40 samples) were randomly selected. Bilateral retromandibular veins and their branches were cleaned. The construction, branches, backstreaming of the retromandibular vein and its relation to the facial nerve and mandibular angle were anatomically observed.RESULTS AND CONCLUSION: The retromandibular vein originated constantly and provided an average length of (4.51±2.01) cm, with an average outer diameter of (0.52±0.28) cm at the origination part. A total of 34 samples showed that the retromandibular vein was formed by the union of the superficial temporal and maxillary veins, and six samples showed that the retromandibular vein originated from the superficial temporal vein. The retromandibular vein divided into two types according to the backstreaming and course: one type consisted of the anterior and posterior branches: the anterior branch mostly drained into the internal jugular vein and minorly drained into the external jugular vein; the posterior branch was joined by the posterior auricular vein and became the external jugular vein. Another type of retromandibular vein without the anterior and posterior branches directly connected with the posterior auricular vein and entered the external jugular vein. The retromandibular vein had the following branches (appearance frequency): facial transverse vein (88%), mandibular articular vein (98%), parotid veins (95%),anterior auricular veins (58%), styloid process vein (43%). 88% of the retromandibular vein was located in the superior and inferior trunks of the facial nerve and in the medial branches. The retromandibular vein connected with facial nerve trunk or major branches in a decussated fashion. 75% of the arc-shaped structures formed by the retromandibular vein and its branches coursed close to the inferior and posterior border of the mandibular angle, and 25% of the arc-shaped structures were not close to the lowest point of the mandibular angle. The thin periosteum between the venous wall and cortical bone was just the position of ostectomy line of mandibular angle. The retromandibular vein was easily injured no matter in vein dissection or ostectomy.

BACKGROUND: MRI is a gold standard for imaging diagnosis of knee joint disease, but it cannot accurately quantitate effusion of knee.OBJECTIVE: To investigate different volume of contrast-medium in the cavity of knee with MRI scanning to provide objective evidence and quantitaive standard for clinical diagnosis of effusion in the cavity of knee.DESIGN, TIME AND SETTING: Quantitative observation was performed in the MRI Room, the First Affiliated Hospital of Chengdu Medical College from October to December 2008.MATERIALS: Ten samples of fresh normal adult knee joint.METHODS: Puncture with the needle retaining in the cavity of knee of normal adult corpse without effusion or pneumatosis was performed, and 1, 5, 10, 15, 20, 30, 40 mL contrast-medium was injected into the cavity. Coronal section, vertical plane and transect were scanned with T2WI, 4 mm thickness and 1 mm interval by MRI.MAIN OUTCOME MEASURES: The distribution of different amounts of contrast agent in the knee cavity and peripheral synovial bursa in knee coronal plane and sagittal cross-sections.RESULTS:?MRI scanning from coronal section: after 10 mL contrast-medium injection, in the center of medial knee joint, high visual signal was seen in the cavity of joint; after 15 mL contrast-medium injection, scanning between femora and patella, high visual signals were observed; after 20 mL contrast-medium injection, scanning by posterior internal and external condyle of knee, high visual signals were found in 80% of internal and external recess of posterosuperior of thighbone.?MRI scaning at 1.5 cm from internal vertical plane of middle knee: after 5 mL contrast-medium injection, high visual signal area appeared in intercondylar eminence, narrowing gradually, and 70% of posterosuperior internal condyle of tibia; after 10 mL contrast-medium injection, high visual signals appeared at the 1/3 point under suprapatellar bursa; after 15 and 20 mL contrast-medium injection, high visual signal appeared in 80% of 1/3 point of suprapatellar bursa; after 30 and 40 mL contrast-medium injection, high visual signal was seen both internal and external recess of posterosuperior knee.?MRI scanning from inframarginal Apex of patella of knee transect: after 5 mL contrast-medium injection, high visual signal appeared in 90% area at 1/3 point posterior articular cavity; after more than 10 mL contrast-medium injection, high visual signal was seen in 70% area of anterior thighbone facet. CONCLUSION: By injecting different volumes of contrast-medium into the knee cavity and peripheral synovial bursa, reference standard can be constructed according to different volumes of effusion, which is significant for diagnosis of effusion of knee cavity and peripheral synovial bursa with MRI.

Objective:To evaluate the clinical effect of minimally invasive extraction of impacted supernumerary teeth.Methods :35 cases of impacted supernumerary teeth were included.Excluding extraction contraindications,preoperative X-ray or dental CT examina-tion was executed to find out the location of the impacted teeth and adjacent anatomical structures.According to the location,operation approach was selected to extract the impacted supernumerary teeth using minimally invasive apparatus.Intraoperative and postoperative feeling of the patients and the complications were recorded.Results:Operation time lasted from 1 0 to 40 minutes,average 1 5 minutes. All patients maintained good comfort in the operation.8.6% patients had postoperative adverse reactions such as mild pain and discom-fort.None had serious reactions.Conclusion:Minimally invasive extraction of impacted supernumerary teeth has less complication and less uncomfort.

Objective To study the possible different effects on primary liver cancer of various types of blood supply demonstrated by DSA via hepatic artery radioimmunotherapy with 131Ⅰ-HAb18F(ab')2.Methods Under thyroid protection and negative dermal sensitivity test,46 times of intraarterial injection with a 0.75 mCi/kg dose of 131Ⅰ labeled murine HCC monoclonal antibody fragment [HAb18F(ab')2] were performed in 30 patients of PLC using the Seldinger technique.The shrinkage rates of tumor volume were analyzed according to hyper,moderate and hypo vascular three types provided by DSA.Results The volume shrinkage rates of hyper and moderate vascular HCC were 60% and 37.5% respectively,while that of 2 cases of hypovascular HCC showed significantly reduction.Conclusion 131Ⅰ-HAb18F(ab')2 internal radioimmunotherapy prossesses certain signification volume shrinkage efficacy on different blood supplies provided by DSA.(J Intervent Radiol,2007,16:243-245)

Objective To analyze the clinical effects of 131I-HAb18F(ab')2 radioimmunotherapy via hepatic artery on PLC with portal vein tumor emboli. Methods Under the condition of thyroid protection and negative dermal sensitivity test, 12 times of intraarterial injection with 131I labeled murine HCC monoclonal antibody fragment HAb18F(ab')2 were performed in 8 patients of PLC complicated with portal vein tumor emboli. A 0.75 mCi/kg dose of 131I was administrated individually into certain target vessel after hepatic artery angiography using Seldinger technique. Results 3 of 7 patients with symptoms of pains showed remission with simultaneous improvement and stabilization in Karnofsky score in 3 and 4 patients respectively. AFP levels decreased about 50%(3/6)in 3 cases among those 6 positives and the values of I.B. and ALT changed within a very narrow range to a certain extent after the treatment. The overall rate of CR + PR was 28.6% and similar better result was obtained in a non-symptomatic diffuse PLC patient.1 year survival rate was 12.5%. Conclusion 131I-HAb18F(ab')2 radioimmunotreating drug(0.75 mCi/kg)with hypotoxicity to liver-function can be used as an acceptable method for unresectable PLC with portal vein tumor emboli, especially for those without tumor emboli in the main trunk.
