16. Iatrogenic abdominal aortic pseudoaneurysm repaired by percutaneous image-guided translumbar embolization.

Abstract

Aortic injury is a frequently encountered condition that can present as a life-threatening emergency. When this injury occurs in the retroperitoneal portion of the aorta, it can be difficult to diagnose and treat because of the location. Although surgical repair remains the mainstay of treatment, surgery might not be an option for some patients. We have presented a case of a 54-year-old nonoperative candidate who had experienced iatrogenic retroperitoneal abdominal aortic rupture with pseudoaneurysm formation. The patient was successfully treated with the novel use of a proven technique: direct percutaneous embolization of the pseudoaneurysm sac via a translumbar approach under image guidance., (© 2020 The Authors.)

Abstract

OBJECTIVE. The purpose of this article was to evaluate the feasibility and efficacy of percutaneous fluoroscopic-guided stone retrieval from the cystic duct and antegrade common bile duct (CBD) stone advancement into the duodenum exclusively through a cholecystostomy tube. MATERIALS AND METHODS. Twenty-one patients with acute cholecystitis and choledocholithiasis or an impacted cystic duct stone who underwent percutaneous cholecystostomy tube placement were retrospectively enrolled in this study. The patients had a contra-indication for cholecystectomy (17 patients because of comorbidities and one who declined surgery) or had failed endoscopic retrograde stone removal attempts (three patients). RESULTS. The 21 patients underwent subsequent percutaneous CBD (17 patients) and cystic duct (nine patients) stone removal on follow-up sessions through the percutaneous cholecystostomy track using moderate sedation. A total of 32 stone removal procedures were performed. Seventeen patients underwent balloon dilatation sphincterotomy, after which the CBD stones were pushed forward into the duodenum using a compliant balloon. Seven patients also had stone removal from the cystic duct by a stone retrieval basket. The primary technical success rate for removal of all CBD and cystic duct stones was 76%. The secondary technical success rate was 100%. The clinical success rate was 74%. All patients tolerated the procedures well without major complication. The clinical follow-up interval ranged from 2 to 2310 days (median, 30 days), with no incidence of postprocedural complications. CONCLUSION. Percutaneous transcholecystic common bile and cystic duct stone removal through an existing cholecystostomy access is a safe and effective procedure that is well tolerated.

18. Formation of a traumatic air cyst and ensuing hemopneumothorax during CT angiography in a patient with Ehlers-Danlos syndrome.

Abstract

Ehlers-Danlos syndrome (EDS) refers to a rare group of genetic disorders that makeup part of the connective tissue disorders consortium. It is characterized by clinical features such as skin hyperextensibility, joint hypermobility, and tissue fragility. A vascular subtype (EDS IV) exists, that predisposes affected patients to vascular injury and is well-known and documented. However, other manifestations of EDS IV are less commonly understood and reported. Though spontaneous pneumothorax has been described in several cases, formation of traumatic air cysts/pneumatoceles with little to no inciting factors has not. This can eventually lead to pulmonary hemorrhage or hemopneumothorax. We present a case of spontaneous formation of a traumatic air cyst with ensuing large-volume hemopneumothorax occurring in a time period of under 3 minutes, between pre- and post-contrast-media administration during CT angiography of the chest., (© 2020 The Authors.
