Purpose: To determine the outcome and predictive factors of clinical success of bronchial artery embolization in life-threatening hemoptysis. Material and Methods: We reviewed all bronchial artery embolization procedures performed for life-threatening hemoptysis between January 2008 and December 2018. The outcomes and predictive factors of clinical success following embolization were evaluated. Results: One hundred and eighty-four bronchial artery embolization procedures performed in 145 patients were eligible for the study. The technical and clinical success rates of the procedures were 170/184 (92.4%) and 129/184 (70.1%), respectively. The unstable hemodynamics and prothrombin time/international normalized ratio >1.5 was associated with lower clinical success rate, while embolization of more than one vessel was associated with higher clinical success rate. Conclusion: Bronchial artery embolization is a safe and effective procedure for controlling bleeding in life-threatening hemoptysis. However, low clinical success rate was noted in patients with unstable hemodynamics and coagulopathy, while multiple vessel embolization was associated with higher clinical success.

Background: Gastrointestinal perforations are a frequent cause of acute abdominal symptomatology for patients in the emergency department. The aim of this study was to investigate the findings of multidetector-row computed tomography of gastrointestinal perforations and analyze the impact of any imaging signs on the presurgical identification of the perforation site. Methods: We retrospectively reviewed emergency MDCT findings of 93 patients submitted to surgery for gastrointestinal perforation at two different institutions. Two radiologists separately reviewed the emergency MDCT examinations performed on each patient, before and after knowing the surgical diagnosis of the perforation site. A list of findings was considered. Positive predictive values were estimated for each finding with respect to each perforation site, and correspondence analysis (CA) was used to investigate the relationship between the findings and each of the perforation types. Results: We did not find inframesocolic free air in sigmoid colorectal perforations, and in rare cases, only supramesocolic free fluid in gastroduodenal perforations was found. A high PPV of perivisceral fat stranding due to colonic perforation and general distension of upstream loops and collapse of downstream loops were evident in most patients. Conclusions: Our data could offer additional information on the perforation site in the case of doubtful findings to support surgeons, especially in planning a laparoscopic approach.

Introduction: Endometriosis is a benign condition characterized by endometrial tissue deposited outside the uterine cavity. Endometriosis characteristics include a well-defined cyst (endometrioma) with or without internal septations and seeding nodules; however, no case of extensive infiltrating abdominopelvic endometriosis have been reported.Case presentation: A 48-year-old female presented with incidentally found a hypervascular lesion in the pelvic cavity from routine checkup ultrasound. The computed tomography (CT) angiography investigation showed pelvic arteriovenous malformation (AVM). She underwent embolization at interventional radiology unit and the CT angiography follow up showed complete occlusion of pelvic AVM. However, eight months after embolization, she came with severe abdominal pain and hypotension. Emergency CT showed a large abdominopelvic mass with hemoperitoneum which was suspected for gynecologic or peritoneal malignancy. Further magnetic resonance image (MRI) was highly suspicious of peritoneum or mesentery malignancy. Surgical tumor removal was performed. The histologic results were negative for malignancy and the tumor was compatible with endometriosis.Conclusion: Extensive abdominopelvic endometriosis is rare, and its imaging findings may not exclude peritoneal malignancy. Therefore, a definite diagnosis via histological investigation is necessary.Â
