Objective:To investigate the recognition and injury prevention strategies of hepatic artery variations during hepatic portal lymphadenectomy. Methods:A retrospective analysis was performed, and 12 patients of hepatic arterial variation among 62 pa-tients with hepatic portal lymphadenectomy were the subjects. The study was conducted in the First Affiliated Hospital of Bengbu Medi-cal College between January 2013 and July 2014. The intraoperative treatment and postoperative complications were recorded. Results:Among 12 cases of hepatic artery variation, we found the following cases:3 cases (25.0%) of Michels' Type III, 2 cases (16.7%) of Mi-chels' Type VI, 1 case (8.3%) of Michels' Type IX, 1 case (8.3%) of Hiatt's Type 6, 2 cases (16.7%) of spatial location variation between right hepatic artery and hepatic duct, 2 cases (16.7%) of left and right hepatic artery originating from a common hepatic artery, and 1 case (8.3%) of right hepatic artery originating from the gastroduodenal artery. No injury of hepatic artery occurred. Two cases had post-operative complications, including 1 case of pancreatic leakage and 1 case of incision infection;postoperative hemorrhage, bile leakage, hepatic abscess did not occur in these two cases. Patients recovered well in general. Conclusion:Hepatic arterial injury can be signifi-cantly reduced by the following:increased familiarity with the various types of hepatic artery variations;complete imaging examina-tions for inspection and evaluation before surgery;and careful and meticulous operations in surgery.

Objective To study the methods and results of endovascular treatment of posterior inferior cerebellar artery (PICA) aneurysms. Methods Twenty-one patients with PICA aneurysms were treated with endovascular treatment. The locations of aneurysm on PICA were evaluated through the DSA. Eight patients received single coil embolization, 5 received liquid Glue embolization, 2 received coil embolization combined with liquid Glue, 2 received coil embolization assisted with stents, and 4 underwent ocelasion of the parent PICA. Outcome was evaluated with the Glasgow outcome scale (COS). Results There were complete (100%) occlusion in 5 patients, near complete (>90% ) occlusion in 2, and incomplete (85%) occlusion in 1 in single coil embolization. Seven patients with Glue embolization (n = 5 ) or combination with coils ( n = 2 ) exhibited complete ( 100% ) occlusion. There were near complete ( >90% ) occlusion in 2 cases with coil assisted with stents. Complete occlusion of the parent PICA was achieved in 3 patients, and near complete occlusion of PICA in one case. One patient suffered from new neurological deficits, and one patient treated with coils and stents died. None of the patients suffered from re-bleeding. These patients received follow-up during a mean period of (22±8) months. Overall long-term outcome was good ( GOS score 4 or 5 ) in 17 patients, poor ( COS score 2 or 3) in 3, and fatal ( GOS score 1 ) in one case. Conclusions According to the location of aneurysms on PICA, aneurysms can be effectively and safely treated with endovaecular embolization.

Objective To review the three-dimensional characteristics and configuration of cranial base arteries of patients with intracranial berry aneurysms. Methods All the 70 patients with intracranial berry aneurysms (83 cases)were admitted from January to December in 2007. Their images of spiral computer angiography (CT) were presented and analyzed retrospectively. The site, size and figures of aneurysms were recorded, especially the variations of cranial base arteries were analyzed. Results Cerebral anterior communicating artery (ACoA) was the frequent site where aneurysms located. Incidence of ACoA aneurysms was 43.37%(36/83), that of posterior communicating artery (PCoA) was 28.92%(24/83), that of internal carotid artery was 9.64% (8/83), that of middle cerebral artery was 6.02% (5/83), that of A1-A3 was 3.61% (3/83), that of basilar artery was 3.61% (3/83), that of posterior cerebral artery was 2.41% (2/83), that of posterior inferior cerebellar artery was 1.20% (1/83),that of anterior choroidal artery was 1.20% (1/83).The shape of many berry aneurysms was regular. Mutational rate of cranial base arteries among aneurysms were 56.63% (47/83) and ACoA ancurysms with A1 dysplasia rate was 72.22% (26/36). Conclusions The solid shape and vascular variation of intracranial berry aneuryams can be optimally identified by spiral computer angiography. The occurrence of berry aneurysms might be associated with variation of cranial base arteries.

Objective To summarize the experience of reconstruction of Ⅴ and Ⅷ hepatic veins in right lobe (without middle hepatic vein) living donor liver transplantation. Methods The clinical data of 55 cases of living donor liver transplantation of right lobe without middle hepatic vein were analyzed, and Ⅴ and Ⅷ hepatic veins were reconstructed. All donors underwent evaluation on the basis of vascular anatomy, GRWR and graft volume/ESLV. Fifty-one grafts underwent reconstruction of Ⅴ and Ⅷ hepatic veins with cold-storage cadaveric iliac veins. Great saphenous vein, varicose umbilical veins, recipient intrahepatic portal veins and recipient intrahepatic veins were used respectively in the remaining 4 cases. Results One recipient died of obstruction of out-flow on the postoperative day 43. One recipient was converted to cadaver donor liver transplantation at the 7th day after operation, because of acute liver function failure. The remaining 53 cases recovered successfully. Conclusion Reconstruction of Ⅴ and Ⅷ hepatic veins with proper materials in right lobe (without middle hepatic vein) living donor liver transplantation is feasible, and the effect is satisfactory.

Abstract： Objective　To retrospectively analyze the investigation and disposal of the COVID-19 outbreak caused by the transmission of the Omicron variant in infected imported cases, and provide basis for COVID-19 outbreak management. Methods　The description epidemiological method was used to describe the COVID-19 outbreak in Sanya City from March 31 to April 15, 2022. The propagation chain was mapped and the experience gained and shortcomings identified in emergency responses were analyzed. Results　The outbreak resulted in 95 reported locally transmitted COVID-19 cases with a incubation period M(P25, P75) of 4 (3, 5) d. In the 95 cases, the proportion of cases detected through close contact screening, centralized isolation, community screening, control area screening, active treatment (examination), and key population screening were 33.68%, 22.11%, 18.95%, 12.63%, 6.32%, 4.21% and 2.11%, respectively. The epidemic spread for 6 generations, causing 5 clusters of outbreaks and 12 cases of cluster disease. The epidemic affected 12 villages/neighborhood committees, 1 bar, 1 hospital, 1 small clinic, 1 farmer's market, 1 large shopping mall and 1 restaurant in 2 districts of Sanya City. The result of gene sequencing was Omicron variant BA.1.1. Through the immediate launch of emergency plans, nucleic acid and antigen testing, controlling close contact between infected persons and close contacts, suspending indoor business sites, central urban control, and temporary suspension, COVID-19 was controlled within 16 days. Conclusions　The transmission chain of this outbreak was clear and was caused by imported cases. Strengthening the management of the pass, doing a good job in information sharing and docking, timely screening for cases, screening, pushing, controlling high-risk groups, and implementing comprehensive control measures, can effectively prevent the spread of the epidemic, providing a reference for the control of epidemic situations in relevant scenarios.

ObjectiveTo determine the incidence,risk factors and measures to prevent biliary complications after ex vivo split liver transplantation (SLT).Method33 ex vivo SLT were performed between June 2006 and September 2010.One patient was excluded from this analysis because of early postoperative death.There were 18 males and 14 females,with a mean age of 33.4 yr (range,6 mo to 65 yr).Biliary reconstruction was carried out by duct-to-duct anastomosis in 20 and Roux-en-Y hepaticojejunostomy in 12 patients.Biliary complication was defined as either bile leak or bile duct stricture which required surgery,interventional radiology or endoscopic treatment.These biliary complications were confirmed by percutaneous tranahepatic cholangiography,endoscopic retrograde cholangiopancreatography,or T-tube cholangiography.ResultThe median follow-up was 13.5 months (3 to 54 mo).Twelve (37.5 ％ ) biliary complications occurred in 11 patients:hepatic parenchymal leak from the transeeted liver surface in 9.3％ (3/32),anastomotic leaks in 12.5％ (4/32),anastomotic strictures in 3.1％ (1/32),stump leaks from the left bile duct in 3.1 ％ (1/32),and ischemic biliary strictures in 9.3％ (3/32).Two patients died of abdominal sepsis in the 8 patients who had biliary leaks.Univariate analysis showed that graft type and biliary reconstruction were not significant risk factors for biliary leaks.ConclusionCompared with whole liver transplantation and living donor liver transplantation,biliary complications of SLT are more common.Prevention and treatment of biliary complications are important factors to improve the result of SLT.
