Objective To study the feasibility and efficacy of endovascular thoracic aortic repair supported by preliminary arterial bypass. Methods From June 2003 to Jan. 2005, eight patients underwent endovascular repair (EVR) combined with supportive arterial reconstruction in the thoracic aorta. Five patients had Debakey type Ⅲ aortic dissection aneurysm (ADA), and the remaining 3 had descending thoracic aortic aneurysm (DTAA), aortic arch aneurysm and aortic arch pseudoaneurysm respectively. The proximal landing zone was measured less than 15 mm in all instances by contrast-enhanced CT scan and digital subtraction angiography. The preliminary right-left axillary bypass was performed in an ADA case in whom the distance from the primary entry site to the origin of the left common carotid artery was longer than 15mm,and the right- left carotid and left carotid-subclavian bypass in the remaining 7 cases. EVR was conducted 1 week after the bypass. Results All procedures were performed successfully. However, the DTAA patient died of the hemispheric cerebral infarction and subsequent multiple system organ failure, albeit the uneventful recovery from the prior cervical reconstruction. Type Ⅱ endoleak occurred at the completion of EVR in the patient receiving the axillary bypass, but disappeared on 3-month CT. No neurological deficits or limb ischemia developed perioperatively or during the follow-up raging from 3 to 22 months, and complete thrombosis of the thoracic aortic false lumen or of the aneurysm/pseudoaneurysm was revealed on CT at 3 months in the 7 patients. Conclusion The adjunctive surgical bypass appeared to be feasible and effective in creating extra proximal landing zone for endovascular thoracic aortic repair, and thus broaden its application.

Objective Analyse the causes,diagnosis and treatment for delayed hemorrhage after distal radical gastrectomy.Methods Retrospective study on 45 patients combined with intro-abdominal hemorrhage after distal radical gastrectomy from January 2008 to June 2013.Results Thirteen patients combined with delayed hemorrhage in these 45 patients,all of 13 patients had intro-abdominal hemorrhage in 1week to 4 weeks after operation.And 5 of the 13 patiens were intermittent intro-abdominal hemorrhage 1 week after operation,these patients were demonstrated the blood come from gastroduodenal artery pseudoaneurysm fracture by CT and DSA examine,and they were cured by interventional embolization.Other 8 patients were marginal ulcer hemorrhage diagnosed by gastroscope,and they stoped bleeding with the help of gastroscope.Conclusions The causes of delayed hemorrhage after distal radical gastrectomy were complicated,and CT,DSA and endoscope can use for diagnosis.What was more,interventional embolization and endoscope were helpful for curing the intro-abdominal hemorrhage,avoiding re-operation.

Objective To probe imaging manifestations of bronchogenic cysts,as that to improve the knowledge of this disease.Methods Imaging features of congenital bronchial cyst in 32 cases confirmed by operation and pathology were analyzed.Results 4 cases of cyst localized in mediastinum ,all were liquid cyst.28 cases of cyst localized in lungs,aqmong them,22 cases were air-liquid cyst and 6 cases were air cyst,the diameter of lesions was 1~10 cm,there were 2 cases with pyothorax,4 cases with pulmonary maldevelopment,one case with brochio-pleural fistula.The cysts appeared as round or similar round,the walls of cyst was thin.The wall of cyst was obscure and there was infiltrating shadow around cysts when in company with infection.Conclusion X-ray and CT are very important in diagnosing congenital bronchial cysts,CT scan is of very help in diagnosing the compley cysts.

Objective To provide an anatomical basis for treatment of coronoid process fractures through an anteromedial elbow approach and evaluate its clinical effects.Methods Forty cadaveric specimens of adult upper limb were dissected to evaluate the anatomical relationships between the median nerve branches and the nearby muscles in the field of the anteromedial elbow approach.On the basis of the anatomical study,10 patients with coronoid fracture were treated from June 2014 to June 2015.They were 7 males and 3 females,from 17 to 63 years of age (average,43 years).By the O'Driscoll classification,there were 2 cases of type Ⅰ1,3 ones of type Ⅰ2,one of type Ⅱ1,3 ones of type Ⅱ2 and one of type Ⅲ2.The anteromedial elbow approach through the intramuscular space between the pronator teres and the flexor carpi radialis was used to reduce and fixate the fractures of unlar coronoid process and to explore and repair the medial collateral ligaments in all the patients.The ranges of extension,flexion and rotation of the elbow joint were measured at the last follow-ups;the function of the elbow was evaluated according to Mayo elbow performance scores (MEPS).Results The main branch of the median nerve ran between the lateral and the medial epicondyles of the humerus,27.34 mm away to the medial epicondyle of the humerus.The mean distance between the first pronator teres nerve branch and the coronoid process was 13.19 mm.The mean distance between the flexor carpi radialis nerve branch and the coronoid process was 47.02 mm.The mean distance from the medial epicondyle to the flexor carpi radialis nerve branch was 64.40 mm.All the patientswere followed up for an average of 12 months (from 6 to 18 months).Fractures united after an average of 1.8 months (from 1.5 to 2.0 months).Deformity,instability,pain or limited motion of the elbow joint was not observed during the follow-ups.At the last follow-ups,the mean flexion-extension arc of the elbow was 133.0° (from 120° to 140°),the mean rotation was 144.5° (from 130° to 160°),and the mean MEPS was 98 points (from 95 to 100 points).Conclusions The anteromedial approach through the intramuscular space between the pronator teres and the flexor carpi radiafis is a reliable and safe access for coronoid process fractures,because it leads to less injury to the median nerve than the anterior approach,and exposes the coronoid more favorably than the medial approach to facilitate reduction and fixation of the fracture fragments.
