ABSTRACT
Purpose@#To evaluate the long-term radiologic and clinical outcomes of stent-graft placement for the treatment of post-pancreaticoduodenectomy arterial hemorrhage (PPAH) based on the imaging findings of stent-graft patency and results of liver function tests. @*Materials and Methods@#We retrospectively reviewed the medical records of nine consecutive patients who underwent stent-graft placement for PPAH between June 2012 and May 2017. We analyzed the immediate technical and clinical outcomes and liver function test results. Stentgraft patency was evaluated using serial CT angiography images. @*Results@#All stent-grafts were deployed in the intended position for the immediate cessation of arterial hemorrhage and preservation of hepatic arterial blood flow. Technical success was achieved in all nine patients. Eight patients survived after discharge, and one patient died on postoperative day 28. The median follow-up duration was 781 days (range: 28–1766 days). Follow-up CT angiography revealed stent-graft occlusion in all patients. However, serum aspartate aminotransferase or alanine aminotransferase levels in all patients were well below those observed in hepatic infarction cases. @*Conclusion@#Stent-graft placement is a safe and effective treatment method for acute life-threatening PPAH. Liver function and distal hepatic arterial blood flow were maintained postoperatively despite the high incidence of stent-graft occlusion observed on follow-up CT.
ABSTRACT
Purpose@#The purpose of this study was to investigate whether routine insertion of peripherally inserted central catheter (PICC) at admission to a hospice-palliative care (HPC) unit is acceptable in terms of safety and efficacy and whether it results in superior patient satisfaction compared to usual intravenous (IV) access. @*Materials and Methods@#Terminally ill cancer patients were randomly assigned to two arms: routine PICC access and usual IV access arm. The primary endpoint was IV maintenance success rate, defined as the rate of functional IV maintenance until the intended time (discharge, transfer, or death). @*Results@#A total of 66 terminally ill cancer patients were enrolled and randomized to study arms. Among them, 57 patients (routine PICC, 29; usual IV, 28) were analyzed. In the routine PICC arm, mean time to PICC was 0.84 days (range, 0 to 3 days), 27 patients maintained PICC with function until the intended time. In the usual IV arm, 11 patients maintained peripheral IV access until the intended time, and 15 patients underwent PICC insertion. The IV maintenance success rate in the routine PICC arm (27/29, 93.1%) was similar to that in the usual IV arm (26/28, 92.8%, p=0.958). Patient satisfaction at day 5 was better in the routine PICC arm (97%, ‘a little comfort’ or ‘much comfort’) compared with the usual IV arm (21%) (p <0.001). @*Conclusion@#Routine PICC insertion in terminally ill cancer patients was comparable in safety and efficacy and resulted in superior satisfaction compared with usual IV access. Thus, routine PICC insertion could be considered at admission to the HPC unit.

ABSTRACT
Objectives@#Terminally ill cancer patients in hospice palliative care unit are reluctant to undergo repetitive invasive procedures due to coagulopathies and poor performance or condition, while catheter management such as regular irrigation during hospitalization is easy. The purpose of this study was to investigate the safety and efficacy of indwelling intraperitoneal (IP) catheter in hospitalized terminally ill cancer patients with recurrent ascites. @*Methods@#A retrospective review was conducted in patients who underwent IP catheter at the hospice palliative care unit of Pusan National University Yangsan Hospital between August 2016 and June 2018. All catheters were inserted by interventional radiologists with radiological guidance. The primary end-points were functional IP catheter maintenance rate, which is catheter maintained with patency for drainage until the intended time. @*Results@#A total of 25 terminally ill cancer patients underwent IP catheters placements during the study period. All catheters were successfully inserted without major complications, but one patient had trivial bleeding and one other patient had temporary pain. The median time from admission to catheter insertion was 5 days (range, 1 to 49 days). Twenty-one catheters were maintained with function until the intended time, three cases were maintained without function, and the last one was removed early due to obstruction and pain. Finally, the functional IP maintenance rate was 84% (21/25) and the median functional catheter life span was 15 days (95% confidence interval, 10.8 to 17.2). @*Conclusion@#Our study showed relatively favorable results for IP catheter maintenance and safety in hospitalized terminally ill cancer patients with malignant ascites.
ABSTRACT
Purpose@#Some patients with neonatal seizures show diffuse, symmetric diffusion-restricted lesions in the cerebral white matter. The aim of this study was to describe clinical and imaging findings of patients with neonatal seizures who had diffuse, symmetric diffusion-restricted lesions without any structural or metabolic etiology. @*Materials and Methods@#A total of 56 neonates aged less than 1 week underwent brain magnetic resonance imaging (MRI) for evaluation of seizures from November 2008 to February 2017. After excluding 43 patients, 13 patients showed diffuse white matter abnormality on diffusion-weighted imaging. Initial and follow-up clinical and MRI findings were analyzed retro-spectively. @*Results@#All 13 patients were born at full term. Among the ten patients who underwent a stool test for viruses, six were positive for rotavirus and one for astrovirus. MRI revealed diffuse, symmetric diffusion-restricted lesions distributed along the cerebral white matter, thalami, and midbrain variably. @*Conclusion@#Diffuse, symmetric diffusion-restricted lesions involving the cerebral white matter can be seen in patients with neonatal seizures without any structural or metabolic etiology. Rotavirus is commonly but not exclusively detected in these patients. Nevertheless, viral infection-associated encephalopathy should be considered for patients with characteristic clinical and MRI findings.
ABSTRACT
We present a case of spontaneous rupture of hepatocellular carcinoma with poor liver function managed by transcatheter arterial embolization (TAE). The patient's bilirubin level was 2.1 mg/dL, albumin level was 2.4 g/dL, and prothrombin time international normalized ratio was 2.1. In addition, the patient had also developed a large number of ascites. The tumor was supplied by the right renal capsular artery, as observed on angiography. With successful TAE, no hepatic failure occurred. We believe TAE can be a safe and effective treatment option, even in patients with poor liver function, if tumors are supplied only by extrahepatic collateral vessels.

Mirizzi syndrome (MS) is a rare complication of cholecystolithiasis that is characterized by obstruction of the common hepatic duct due to mechanical compression by impacted stones in the neck of the gallbladder or the cystic duct. Treatment of MS is surgical, and operative procedure would vary depending on its classification type. Biliary stricture after surgical treatment of MS is an unusual complication and endoscopic approach is not possible for patients who have undergone bilioenteric anastomosis. We report a case of a 60-year-old patient with biliary anastomotic stricture after surgical management of MS who was successfully treated with long-term percutaneous transhepatic biliary drainage.

Spontaneous rupture with internal bleeding of solid tumors has rarely been described at the time of diagnosis or during chemotherapy. This rare event must be regarded as a life threatening condition. In these emergency situations, control of hemorrhage, which is life-saving, can be achieved by transcatheter arterial embolization (TAE) and/or surgical resection. This report describes two infants presenting with acute hemorrhagic shock due to spontaneous tumor rupture of hepatoblastoma and neuroblastoma during chemotherapy. TAE successfully arrested the tumor bleeding and a visibly reduced the tumor size in both children. Spontaneous rupture of solid tumors occur infrequently in children, but is a life threatening situation. Careful monitoring for the occurrence of this rare event especially in very young children presenting with a large tumor mass.

We report a case of percutaneous transhepatic stent placement for the treatment of hepatic venous outflow obstruction after extracorporeal hepatic resection and autotransplantation. A 63-year-old woman with a large mass in the liver was asymptomatic with no hepatic virus infection. Because the tumor was unresectable by conventional means, we used extracorporeal hepatic resection and autotransplantation for operation. Two days after surgery, hepatic venous outflow obstruction of the right and right inferior hepatic veins was suspected on computed tomography. After failure of the transjugular approach, hepatic venous stenting was performed successfully via the percutaneoustranshepatic approach.

PURPOSE: A duodenal stump fistula is one of the most severe complications after gastrectomy for gastric cancer. We aimed to analyze the risk factors for this problem, and to identify the methods used for its prevention and management. METHODS: We retrospectively reviewed the clinical data of 716 consecutive patients who underwent curative gastrectomy with a duodenal stump for gastric cancer between 2008 and 2013. RESULTS: A duodenal stump fistula occurred in 16 patients (2.2%) and there were 2 deaths in this group. Univariate analysis revealed age >60 years (odds ratio [OR], 3.09; 95% confidence interval [CI], 0.99-9.66), multiple comorbidities (OR, 4.23; 95% CI, 1.50-11.92), clinical T stage (OR, 2.91; 95% CI, 1.045-8.10), and gastric outlet obstruction (OR, 8.64; 95% CI, 2.61-28.61) to be significant factors for developing a duodenal stump fistula. Multivariate analysis identified multiple comorbidities (OR, 3.92; 95% CI, 1.30-11.80) and gastric outlet obstruction (OR, 5.62; 95% CI, 1.45-21.71) as predictors of this complication. CONCLUSION: Multiple comorbidities and gastric outlet obstruction were the main risk factors for a duodenal stump fistula. Therefore, preventive methods and aggressive management should be applied for patients at high risk.

This report details a case of post-traumatic pseudocyst in the spleen that was successfully treated with sclerotherapy using ethanol. A sixteen-year-old boy visited our hospital for a follow-up examination of a splenic cyst. He had experienced blunt trauma to the abdomen three years prior to presentation. An abdominal computed tomography scan revealed a large cyst of the lower pole of the spleen. The cyst was 6.8x9.5x7.0 cm and conservative management was tried. A follow-up ultrasonographic examination three years later revealed that the size of the cyst was unchanged and another treatment was needed to prevent complications. One session of sclerosis with ethanol (90 mL of 99% ethanol) percutaneously was applied to the cyst. A follow-up after four months revealed that the cyst had completely resolved.

Iatrogenic pseudoaneurysms are extremely rare in children. Conventional management of pseudoaneurysms in adults has included surgical repair, ultrasound-guided compression, and more recently, endovascular embolization. However, in infants and children, there is little information regarding the applicability of such treatment modalities, which have been effective in adults, because of its rarity. Here, we present the case of a 6-month-old infant who developed a postprocedural pseudoaneurysm of the external iliac artery, which was successfully treated with ultrasound-guided percutaneous thrombin injection.

BACKGROUND/AIMS: Approximately 5% to 10% of common bile duct (CBD) stones are difficult to remove by conventional endoscopic methods. Percutaneous transhepatic cholangioscopic lithotomy (PTCSL) can be an alternative method for this condition, but is not well established yet. The aim of this study was to evaluate the clinical efficacy and safety of PTCSL for removal of difficult CBD stones. METHODS: This study is a retrospective review of 34 consecutive patients who underwent unsuccessful removal of CBD stones using conventional endoscopic methods between December 2008 and July 2010 and were subsequently treated using PTCSL. RESULTS: Among 443 patients with CBD stones, 34 patients (7.8%) failed to achieve stone removal using conventional endoscopic methods. Of these 34 patients, 33 were treated using PTCSL. In all 33 cases (100%), complete stone removal was achieved using PTCSL. Most complications (15/17, 88.2%) were mild and transient. Major complications occurred in two patients (6.1%) who experienced hemobilia, and percutaneous transhepatic biliary drainage tract disruption, respectively; which were fully recovered without mortality. CONCLUSIONS: Despite prolonged hospital stay and temporary decline of quality of life, PTCSL is an effective and safe method in the management of difficult CBD stones, especially in patients with difficulty in approaching the affected bile duct.

Castleman's disease is an uncommon disorder characterized by benign proliferation of the lymphoid tissue that occurs most commonly in the mediastinum. Although unusual locations and manifestations have been reported, involvement of the renal parenchyma and sinus, and moreover, manifestations as cardiac tamponade are extremely rare. Here, we present a rare case of Castleman's disease in the renal parenchyma and sinus that also accompanied cardiac tamponade.

PURPOSE: To determine the clinical utility of coronary CT angiography (CCTA) with low-dose chest CT in the evaluation of patients with atypical chest pain. MATERIALS AND METHODS: Ninety-six patients (mean age 60.2 years; age range, 41-68 years; 70 males) were referred for CCTA with low-dose chest CT (16-slice MDCT, Siemens) for an evaluation of atypical chest pain. When significant stenoses (lumen diameter reduction > 50%) were detected on CCTA, invasive coronary angiography (CA) was performed as the standard of reference. In all patients, medical chart review or telephone contact with patients was used to evaluate the contribution of CCTA with low-dose chest CT to the final clinical diagnosis, at least 6 months after performing CCTA. RESULTS: Among 96 patients, seven patients (7%) had significant stenoses as detected on CCTA, whereas two patients (2%) had significant stenoses and five patients had insignificant stenoses or no stenosis, as detected on conventional catheter angiography. In 18 (19%) of the 89 patients without significant stenosis detected on CCTA, this protocol provided additional information that suggested or confirmed an alternate clinical diagnosis. CONCLUSION: In patients with atypical chest pain, CCTA with low-dose chest CT could help to exclude ischemic heart disease and could provide important ancillary information for the final diagnosis.

PURPOSE: To compare the clinical results of BRTO in the gastric varices with those of TIPS. MATERIALS AND METHODS: From January 2004 to March 2006, eight patients who had been followed up for more than 1 month after BRTO were enrolled in this study. This study compared the clinical efficacy of BRTO with that of TIPS in 13 patients who had undergone TIPS from January 2000 to March 2006. The change in laboratory parameters before and after each procedure and the incidence of rebleeding, encephalopathy, asictes and varices were analyzed after each procedure. Results:In the BRTO group, the level of albumin increased, and the levels of ammonia and the Child-Pugh score decreased. The TIPS group showed no improvement in the liver function. In the BRTO group, the gastric varices were eradicated in 7 patients. Gastric variceal rebleeding and encephalopathy did not occur. However, the esophageal varices worsened in 6 patients. In the TIPS group, rebleeding (n=4), encephalopathy (n=7) and a worsening of the gastric (n=5) or esophageal varices (n=2) occurred. CONCLUSION: BRTO improves the metabolic activity of the liver and has a lower incidence of encephalopathy. Hence, BRTO is a good alternative to TIPS in the gastric varices accompanied by a gastrorenal shunt although a treatment for a worsening of the esophageal varices may be needed after BRTO.
