Anomalous retro-psoas artery is an extremely rare congenital anomaly of the iliac arteries reported in the English-language literature. Using contrast-enhanced computed tomography, we incidentally diagnosed an anomalous retro-psoas artery in a 60-year-old male patient with right renal cancer. Although anomalous retro-psoas artery is extremely rare and mostly asymptomatic, knowledge of it is needed to avoid severe vascular complications in the event of vascular intervention and surgery.
Intranodal embolization using n-butyl cyanoacrylate glue is an emerging treatment option for persistent lymphatic leakage. This report describes the procedure details of intranodal embolization for groin lymphocele and evaluates the efficacy of intranodal embolization at our institution via retrospective chart review.Material and Methods: Nine consecutive patients (six men and three women; median age, 77.4 years; range, 43-95 years) who underwent intranodal embolization for groin lymphocele between January 2017 and December 2019 were included as study subjects. Intranodal lymphangiography with iodinated contrast was performed to confirm lymphatic leakage, followed by intranodal embolization using n-butyl cyanoacrylate glue mixed with iodized oil for all nine patients. The etiologies of lymphocele, technical and clinical success rates of intranodal embolization, duration of treatment, follow-up period, and acute and chronic complications were retrospectively investigated.Results: The etiologies of groin lymphoceles were the cutdown access of inguinal vessels (n = 7), lymph node biopsy (n = 1), and trauma (n = 1). The technical and clinical success rates of both lymphangiography and subsequent intranodal embolization were 100%. For intranodal embolization, 16.7%-33.3% n-butyl cyanoacrylate glue was used. The median duration of treatment was 2 days (range, 1-13 days). The follow-up period lasted 0-895 days (median, 9 days). No acute or chronic complications were observed.Conclusions: In this study, intranodal embolization showed promising results for groin lymphocele with a short duration of treatment with a median of 2 days. Intranodal embolization using n-butyl cyanoacrylate glue could be a treatment option for persistent groin lymphocele. However, further research is warranted to further evaluate the efficacy of intranodal embolization.
Purpose: Although percutaneous stent placement for malignant inferior vena cava syndrome is a highly feasible and effective treatment option, there is no clear evidence for the necessity of prophylactic anticoagulation therapy after inferior vena cava stent placement. This study retrospectively evaluated the necessity of prophylactic anticoagulation following inferior vena cava stent placement in patients with malignant inferior vena cava syndrome. Methods: The data of 54 patients (28 men and 26 women; median age 61.2 years) with malignant inferior vena cava syndrome who received inferior vena cava stent placement between 2011 and 2021 were retrospectively reviewed. Prophylactic anticoagulation was administered to 15 of 54 patients (27.8%) following stent placement. Symptom recurrence rates at 1 and 2 months after stent placement were compared between patients with and without prophylactic anticoagulation using Gray relational analysis. The timeline of symptom recurrence, survival time, and adverse events were also evaluated. Results: At 1 and 2 months, symptom recurrence rates were 48.6% and 71.4%, respectively, in patients with prophylactic anticoagulation and 28.3% and 37.0%, respectively, in patients without prophylactic anticoagulation. The overall median follow-up duration was 27 days and that of the patients with and without prophylactic anticoagulation was 37 and 25 days, respectively. The median survival times of patients with and without anticoagulation therapy were 69 and 30 days, respectively (p = 0.236). No procedure-related complications occurred. Conclusions: There was no significant difference in the symptom recurrence rates after inferior vena cava stent placement with or without prophylactic anticoagulation in this study.
Purpose The aim of the study is to evaluate the feasibility, safety, and efficacy of the trans-colostomy placement of a button gastrostomy tube for patients with malignant bowel obstruction due to peritoneal carcinomatosis. Material and Methods Data from seven consecutive patients who presented with malignant bowel obstruction due to peritoneal carcinomatosis involving the colostomy site and underwent trans-colostomy button gastrostomy tube placement between 2013 and 2020 were retrospectively reviewed. We assessed technical and clinical success rate, procedure time, duration of improvement, and complication rate. Results The technical success rate of the trans-colostomy button gastrostomy tube placement was 100%, and average procedure time was 25 minutes. Clinical symptoms of malignant bowel obstruction resolved in four out of seven (57%) patients. Average duration of improvement in the four patients with clinical success was 170.8 days. There were no complications associated with the procedure. Conclusion Trans-colostomy button gastrostomy tube placement might be a safe and feasible treatment option for patients with malignant bowel obstruction due to peritoneal carcinomatosis.
