Objective To explore the effect of latissimus dorsi musculocutaneous flap for repairing severe soft tissue defect of the elbow.Methods Seventeen patients with severe soft tissue defect of the elbow were repaired by latissimus dorsi musculocutaneous flap.Ten patients were performed transfer of skin flap for functional reconstruction,9 patients reconstructed elbow flexion,and 1 patient reconstructed elbow extension.Seven patients' tissue defect were repaired by cover type musculocutaneous flap,and the areas of these flaps ranged from 6 cm × 10 cm-12 cm × 27 cm.Results All the musculocutaneous flaps kept alive.After an average postoperative follow-up for 12-40(22.0 ± 9.6) months,the color and luster of the flaps were satisfying.There were no scar contracture of the flap and no bulkiness of the elbow.Ten patients performed transfer of skin flap for functional reconstruction,and the range of motion was 100°-140° of flexion and-20°-0° of extension.Muscle power was M3-M5.Hand function was near normal.Conclusion Latissimus dorsi musculocutaneous flap is an ideal surgical method to repair the severe soft tissue defect of the elbow.

Objective To evaluate the therapeutic effect of transarterial chemoembolization (TACE) combined with CT-guided 125I seed implantation in treating hepatocellular carcinoma (HCC) complicated by portal vein tumor thrombus(PVTT), and to discuss the technical points. Methods A total of 48 HCC patients with PVTT were enrolled in this study. TACE combined with CT-guided 125I seed implantation was carried out in all 48 patients. Based on the sites of PVTT, the lesions were classified into type A (PVTT within main portal vein), type B(PVTT within level-1 portal branch) and type C(PVTT within level-2 or more distal portal branch). According to whether the 125I seeds were directly implanted into the PVTT or not, the patients were divided into direct in-tumor thrombus implantation group (group A) and around tumor thrombus implantation group (group B; the 125I seeds were implanted in the liver parenchyma or in tumor tissue around the tumor thrombus within 1.7 cm region). The tumor thrombus control rate(TTCR), the disease control rate(DCR), the time to progress(TTP) and the overall survival rate of patients(OS) were determined, and the results were compared among different types and groups. Results TACE combined with CT-guided 125I seed implantation was successfully accomplished in all 48 patients. The median OS of type A, B and C was 8, 11.5 and 15 months respectively(P=0.003);the TTCR of type A, B and C was 61.5%, 70.8%and 72.7%respectively(P=0.548); the DCR of type A, B and C was 69.2%, 75%and 81.8% respectively (P=0.483); the median TTP of type A, B and C was 4.5, 8 and 11 months respectively(P=0.030);the median TTP of intra-hepatic tumor of type A, B and C was 5, 9 and 9.5 months respectively(P=0.012). The median OS in group A and group B was 10 and 11.5 months respectively (P=0.239); the TTCR in group A and group B was 69.2% and 68.2%respectively(P=0.591); the DCR of intra-hepatic tumor in group A and group B was 73.1% and 77.3%respectively(P=0.502); the median TTP of tumor thrombus in group A and group B was 7 and 10 months respectively(P=0.276); and the median TTP of intra-hepatic tumor in group A and group B was 8 and 9.5 months respectively(P=0.089). Conclusion For the treatment of hepatocellular carcinoma complicated by portal vein tumor thrombus, TACE combined with CT-guided 125I seed implantation can effectively control the progress of both the tumor thrombus and the intra- hepatic tumor and prolong patient’s survival time. Implantation of 125I seeds into the portal vein tumor thrombus and implantation of 125I seeds into the liver parenchyma around the tumor thrombus have the same therapeutic results.

Objective To investigate the diagnosis and treatment of isolated celiac artery (CA) dissection and superior mesenteric artery (SMA) dissection.MethodsIntegrating clinical data of 119 cases with isolated dissection of the visceral arteries ( IDVA ) reported in literature and 2 patients with spontaneous isolated dissections of both CA and SMA treated in the Third Affiliated Hospital of Sun Yat-sen University,the diagnosis and treatment of IDVA were analyzed retrospectively.Results Among 119 cases reported in the literature,69 cases were symptomatic.All of the cases were diagnosed by contrast-enhanced abdominal CT or MRI.After IDVA was discovered,surgical treatment and endovascular stent placement was performed in 8 and 5 patients respectively,although the remaining 106 patients were managed conservatively with good results.In our 2 cases,the diagnosis of CA and SMA dissection was established by contrastenhanced CT and confirmed by conventional angiograghy.One patient was treated with anticoagulation and antihypertension,and the other patient was treated with endovascular stenting.Both of the patients didn't have discomfort during the follow-up period of 12 and 3 months respectively.ConclusionsContrastenhanced abdominal CT is the main tool for detection of IDVA.Most of the patients with IDVA can be managed conservatively,but close surveillance with imaging studies is necessary for early recognition of dissection progression.Patients with persistent or relapsed symptoms,and dissection progression,should undergo surgical or endovascular treatment.

Objective To investigate the clinical outcome and treatment of portal vein thrombosis (PVT) following partial splenic embolization (PSE).Methods From April 2006 to April 2010,105patients with hypersplenism caused by cirrhotic portal hypertension were treated with PSE.Contrastenhanced abdominal computed tomography or magnetic resonance imaging was performed routinely in 60patients before PSE and 1 -3 months after PSE.PVT was detected in 10 patients on images after the procedures.After PVT was diagnosed,4 patients received anticoagulant therapy immediately,and the other 6 patients did not receive therapy.Clinical data of these 10 PVT patients were analyzed retrospectively.Results 3 of 4 patients who received anticoagulant therapy had complete or partial resolution of the thrombus,and one developed mild ascites without thrombosis progression.Of the 6 patients who did not receive anticoagulant therapy,follow-up studies (6- 48 months,mean 16.9 months) demonstrated partial clot calcification in one,thrombosis progression in 5.Among those 5 patients with thrombosis progression,two experienced hematemesis due to variceal rupture and underwent transjugular intrahepatic portosystemic shunt,2 developed cavernous transformation,extensive collateral circulation,ascites and variceal progression,and one had variceal progression with melena during the follow-up period.Conclusions PVT is a severe complication of PSE.Early diagnosis and prompt anticoagulant therapy is effective in preventing PVT.

Objective To analyze the internal relationship between phlegm stasis syndrome (痰浊内阻证) and blood stasis syndrome (血瘀证) in cases with carotid atherosclerosis. Methods The clinical data of 136 patients with atherosclerosis accompanied by phlegm stasis and blood stasis syndromes were collected from the investigation table of the 4 diagnostic methods in traditional Chinese medicine(TCM); the principal components of the clinical data were statistically analyzed, and the correlative relationships of these principal components were studied. Results There were two principal components of phlegm stasis syndrome, which were tz1 and tz2. And tz1 cumulated 42.645% to phlegm stasis syndrome, which could be considered as phlegm stasis in limbs and tunnel; tz2 cumulated 24.898% to phlegm stasis syndrome, which could be considered as phlegm stasis in the body that might impair the 7 orifices (such as eyes, ears, nose and mouth). And they could also be considered as special markers of phlegm stasis syndrome of carotid atherosclerosis. There were three principal components of blood stasis syndrome, which were xy1, xy2 and xy3. And xy1 cumulated 37.197% to blood stasis syndrome, which could be considered as blood stasis in the artery and tunnel; xy2 cumulated 21.627% to blood stasis syndrome, which could be considered as the blood outside the vessels located in the body and could obstruct tunnel and could not nourish muscle and skin; then, xy3 cumulated 13.685% to blood stasis syndrome, which could be considered as the blood stayed in the brain and could not nourish brain and might reflect as a special marker of blood stasis syndrome of carotid atherosclerosis. There was significant positive correlative relationship between phlegm stasis syndrome principal component 1 and blood stasis syndrome principal component either 1 or 2 (P
