Image-Guided Biliary Interventions: How to Recognize, Avoid, or Get Out of Trouble.

Percutaneous biliary interventions have a well-established role in the management of hepatobiliary diseases. Good outcomes include recognizing and avoiding complications. This section will cover the "standard" technique of percutaneous biliary drainage, pearls to decrease the risk of problems, and approaches to treat those complications in patients undergoing percutaneous transhepatic cholangiography and percutaneous transhepatic biliary drainage.

Percutaneous Gastrostomy: How to Recognize, Avoid, or Get Out of Trouble.

Placement of gastrostomy tubes can be done with different techniques. The radiologic-guided tube placement relies on image guidance for safe placement of the tube. A thorough knowledge of the immediate and delayed hazards is essential. This article outlines the potential complications and how to recognize, avoid, and treat them. Several clinical examples are included. Key Words: gastrostomy, complication, feeding tubes, image guidance.

Image-Guided Nephrostomy Interventions: How to Recognize, Avoid, or Get Out of Trouble.

Image-guided percutaneous nephrostomy is a relatively safe and successful procedure for access to the renal collecting system for multiple purposes including relief of urinary obstruction, urinary diversion, access for endourologic procedures, and diagnostic testing. Although placing a percutaneous nephrostomy catheter is most times straightforward, providing immediate benefit for the patient and satisfaction for the practitioner, there can be situations that make the procedure more difficult or risky. A thorough review of the patient's imaging and medical record will help to set a path for success. However, there may be innuendos and unforeseen circumstances that occur. Having knowledge of most of these "stumbling blocks" and how to deal with them will keep you on the path. This paper serves to fill some of that mental file with the aim to increase clinical success.

Restoration of Completely Transected Common Bile Duct Continuity Using Single Operator Cholangioscopy.

Common bile duct (CBD) injury, ranging from a partial tear to a complete transection, is a major surgical complication of cholecystectomy with significant morbidity and mortality. Proper management of these complex injuries depends on the type and extent of injury and time of recognition. Identifying and repairing injuries during cholecystectomy can prevent development of complications, but this only occurs in about one-third of cases. We report a novel technique to reconnect a transected CBD with assistance of single-operator cholangioscopy.

Congenital bronchial artery to pulmonary artery fistula presenting as hemoptysis.

A 51-year-old male presented with 2 weeks of hemoptysis. Pulmonary angiography was performed and identified a bronchial artery to pulmonary artery fistula of the right upper lobe. Despite angioembolization, the hemoptysis recurred 1 year later. It was hypothesized that the recurrence occurred due to retrograde filling from the pulmonary arterial side of the abnormality. Right upper lobectomy was performed and resulted in resolution of hemoptysis. We present a case report of a rare, congenital bronchial artery to pulmonary artery fistula.

Transcatheter embolization for delayed hemorrhage caused by blunt splenic trauma.

Although the exact benefit of adjunctive splenic artery embolization (SAE) in the nonoperative management (NOM) of patients with blunt splenic trauma has been debated, the role of transcatheter embolization in delayed splenic hemorrhage is rarely addressed. The purpose of this study was to evaluate the effectiveness of SAE in the management of patients who presented at least 3 days after initial splenic trauma with delayed hemorrhage. During a 24-month period 4 patients (all male; ages 19-49 years) presented with acute onset of pain 5-70 days after blunt trauma to the left upper quadrant. Two had known splenic injuries that had been managed nonoperatively. All had computed axial tomography evidence of active splenic hemorrhage or false aneurysm on representation. All underwent successful SAE. Follow-up ranged from 28 to 370 days. These cases and a review of the literature indicate that SAE is safe and effective for NOM failure caused by delayed manifestations of splenic arterial injury.
