An enlarged spleen is considered one of the most common signs of malaria, and splenic rupture rarely occurs as an important life-threatening complication. Splenectomy has been recommended as the treatment of choice for hemodynamically unstable patients. However, a very limited number of splenic rupture patients have been treated with transcatheter coil embolization. Here we report a 38-year-old Korean vivax malaria patient with ruptured spleen who was treated successfully by embolization of the splenic artery. The present study showed that angiographic embolization of the splenic artery may be an appropriate option to avoid perioperative harmful effects of splenectomy in malaria patients.

The aneurysms at the initial segment of splenic artery are rare. This paper aimed to investigate the methods to treat the true aneurysm at the initial segment of splenic artery by aneurysmectomy plus vascular reconstruction. Retrospectively reviewed were 11 cases of true aneurysm at the initial segment of splenic artery who were treated in our hospital from January 2000 to June 2013. All cases were diagnosed by color ultrasonography, computer tomography (CT) and angiography. Upon resection of the aneurysm, the auto-vein transplantation was performed in situ between the hepatic artery and the distal part of the splenic artery in 1 case; the artificial vessel bypass was done between the infra-renal aorta and distal portion of the splenic artery in 7 cases; the splenectomy was done in 2 cases; the splenectomy in combination with ligation of multiple small aneurysms were performed in 1 case. All cases were cured and discharged from the hospital 10-14 days after operation. A 1-14 year follow-up showed that 9 cases survived, and 2 cases died, including 1 case who died of acute myocardial infarction 2 years after aorta-splenic artery bypass operation and 1 case who died of acute cerebral hemorrhage 5 years after aneurysm resection and the splenectomy. Among 6 cases receiving aorta-splenic artery bypass, 1 gradually developed stenosis at anatomosed site, which eventually progressed to complete occlusion 2 years to 6 years after operation, without suffering from splenic infarction because the spleen was supplied by the short gastric vessel and its collaterals. The other 5 cases receiving aorta-splenic artery bypass and 1 case undergoing autologous vascular transplantation did not develop stricture or pseudoaneurysm at the stoma. Our study showed that the aneurysmectomy plus vascular reconstruction is a better treatment for aneurysm at the initial segment of splenic artery.

OBJECTIVETo discuss the risk factors of splenic arterial steal syndrome (SASS) after orthotopic liver transplantation.

METHODSTwenty-four cases who confirmed SASS after liver transplantation in Tianjin First Central Hospital between June 2005 and June 2013 were analyzed retrospectively. Another 96 cases were selected randomly from those patients of the same time with no complication of SASS patients postoperatively as control group. Clinical data of two groups including diameter of splenic artery and hepatic artery preoperatively, weight of graft, weight of recipients, cold/warm ischemia time, an hepatic period and operation time and so on were collected. Others including hepatic artery peak systolic velocity (PSV), end diastolic velocity (EDV), blood flow resistance index and portal vein average velocity (PVF) on the first day after liver transplantation, the day before diagnosis, the day when diagnosed, the 1, 3, 7 days after treatment in SASS group and on 1, 3, 7, 9, 11, 14 days after liver transplantation in control group. Statistical analysis were made between two groups.

RESULTSThe splenic artery/hepatic artery ratio preoperatively and weight of donor liver,and the GRWR in SASS group and control group were 1.26 and 1.00, 1 032 g and 1 075 g, (1.40±0.30)% and (1.82±0.21)% respectively, with significantly statistical differences (Z=-6.40, Z=-2.22, t=-6.50; all P<0.05). The warm ischemia time, the cold ischemia time, the anhepatic period and operation time in SASS group and control group were 3.5 minutes and 4.0 minutes, 10.25 hours and 10.10 hours, 43 minutes and 45 minutes, 8.7 hours and 8.7 hours, with no significantly statistical differences (all P>0.05). RI of hepatic went up gradually in the early time after transplantation while dropped obviously when spleen artery spring coils embolization was received (P<0.01) and trended to stable two weeks later.

CONCLUSIONSSplenic artery/hepatic artery ratio and GRWR are the positive and negative risk factors respectively for SASS. The gradual rising of hepatic RI in the early time after transplantation may be the warning signal SASS and spleen artery spring coils embolization is the effective strategy for SASS after liver transplantation.

We report a rare case of aneurysm of splenic artery arising anomalously from the superior mesenteric artery (SMA). The aneurysm was treated successfully by coil embolization of the splenic artery distal to aneurysm and then deploying a stent graft in the SMA. A combination of stent graft and coil embolization for the treatment of aberrant splenic artery aneurysm has been reported only once. We describe the imaging findings and the endovascular procedure in this patient.

INTRODUCTIONKnowledge of anatomical variations of the great vessels of the abdomen, including the coeliac trunk, is important for clinicians planning surgical intervention and radiological imaging. The present study aimed to record the prevalence of variations in the vascular pattern of branches of the coeliac trunk in cadavers.

METHODSA total of 50 properly embalmed and formalin-fixed cadavers from the Indian population were selected for the study. Dissection included surgical incision, followed by mobilisation of the anatomical viscera, to observe and record the branching pattern of the coeliac trunk.

RESULTSThe left gastric, common hepatic and splenic arteries were found to arise from the coeliac trunk in 86% of cadavers. In 76% of cadavers, the origin of the gastric artery was proximal to the bifurcation of the coeliac trunk into the common hepatic and splenic arteries. In one case, all three branches arose directly from the abdominal aorta, and the origin of the splenic artery was 1 cm distal to the origin of the left gastric and common hepatic arteries. In another case, the common hepatic and left gastric arteries arose from the coeliac trunk, and the origin of the splenic artery was 1.5 cm distal to the abdominal aorta.

CONCLUSIONVessel ligation and anastomosis are important in surgical procedures like liver transplantation, and background knowledge of the different vascular patterns of branches of the coeliac trunk is vital. The findings of our study could help to minimise complications related to abdominal surgery, including bleeding and necrosis, and facilitate better and more accurate radiological interpretations.

OBJECTIVETo evaluate the effect of partial splenic embolization (PSE) in prevention of gastroesophageal variceal rebleeding.

METHODSSixty-two patients with recent gastroesophageal variceal bleeding were treated by PSE with Seldinger technique. All the patients were followed-up for 12 months. The data including peripheral blood cell count, liver function, plasma prothrombin time (PT), portal vein diameter, and appearance of gastroesophageal varices under gastroscopy were collected before and after embolization for statistical analysis.

RESULTSFive days after the operation, the numbers of leucocytes and platelets were significantly increased (P<0.05), and PT was significantly shortened (P<0.05). All the patients showed a good response after PSE with reduced internal diameter of the portal vein and blood flow (P<0.05). Gastroesophageal varices were relieved in all the patients. Rebleeding occurred in 11 patients during the follow-up.

CONCLUSIONPSE can be effective in preventing gastroesophageal variceal rebleeding.

OBJECTIVETo analyze the experience with diagnosis and surgical treatment of visceral artery aneurysms (VAAs).

METHODSFrom June 2003 to December 2008, 8 patients (2 male and 6 female) with 9 VAAs underwent surgical treatment. Mean age was 49 years (ranged from 30 to 72 years). The site of aneurysmal disease was splenic artery in 4 cases, superior mesenteric artery in 2 cases, renal artery in 2 cases (3 aneurysms). In 1 patient of splenic artery aneurysm, portal vein hypertension coexisted. All the VAAs of preoperative diagnostic workup consisted of a ultrasound, computed tomography (CT) scan, and digital subtraction angiography. Six patients were operated on and two patients was treated with endovascular procedures. Only one small VAAs was treated with follow-up.

RESULTSNo deaths or major complications occurred in the perioperative period. All the patients remained symptom free during a follow-up of 26.5 months (ranged from 2 to 60 months). Follow-up consisted of clinical and ultrasound scan examinations or CT scan at 1 and 6 months, and yearly thereafter.

CONCLUSIONSAggressive approach to the treatment of VAAs is essential. Elective open surgical treatment and an endovascular procedure of visceral artery aneurysms are both safe and effective, and offers satisfactory early and long term results. There is some evidence that small (< 2 cm) and asymptomatic VAAs may be safely observed.

OBJECTIVETo summarize the clinical feature of splenic artery aneurysms (SAA) in OLT recipient, and review the experience in diagnosis and management.

METHODSThe clinical data, results of four-phase CT scanning and CT angiography of 450 recipients, who underwent OLT from December 2001 to December 2003 were analyzed statistically.

RESULTSTwenty of 450 recipients were diagnosed as SAA, the incidence was about 4.4%. Nineteen of them were diagnosed by four-phase CT scanning. Fifteen patients did not receive any treatment for SAA during OLT, but two of them suffered SAA rupture after OLT, among which one died of hemorrhagic shock although emergency operations were performed. The five patients, who were performed splenectomy with SAA resection during transplantation, recovered successfully after OLT, and their grafts' function was satisfactory.

CONCLUSIONSMorbidity of SAA is higher in patients of liver cirrhosis. Four-phase CT scanning can diagnose SAA exactly. In the early period post-OLT, SAA rupture happens frequently, so SAA resection should be performed during transplantation.
