Percutaneous Transhepatic Drainage of Inaccessible Abdominal Abscesses Following Abdominal Surgery Under Real-Time CT-Fluoroscopic Guidance

This study evaluated the safety, feasibility, and clinical utility of transhepatic drainage of inaccessible abdominal abscesses retrospectively under real-time computed tomographic (CT) guidance. For abdominal abscesses, 12 consecutive patients received percutaneous transhepatic drainage. Abscesses were considered inaccessible using the usual access route because they were surrounded by the liver and other organs. The maximum diameters of abscesses were 4.6–9.5 cm (mean, 6.7 ± 1.4 cm). An 8-Fr catheter was advanced into the abscess cavity through the liver parenchyma using real-time CT fluoroscopic guidance. Safety, feasibility, procedure time, and clinical utility were evaluated. Drainage catheters were placed with no complications in abscess cavities through the liver parenchyma in all patients. The mean procedure time was 18.8 ± 9.2 min (range, 12–41 min). All abscesses were drained. They shrank immediately after catheter placement. In conclusions, this transhepatic approach under real-time CT fluoroscopic guidance is a safe, feasible, and useful technique for use of drainage of inaccessible abdominal abscesses.     

Mediastinal abscess successfully treated by percutaneous drainage using a unified CT and fluoroscopy system

We report two patients with mediastinal abscess developing after surgery for oesophageal cancer who were treated by percutaneous drainage using a unified CT and angiography system, which allows both CT and fluoroscopy to be conducted with the patient on the same bed. Fine needle puncture is performed under CT guidance and this needle is used as a tandem for insertion of the drainage needle under fluoroscopic guidance, making safe puncture possible whilst confirming the position of the needle tip. Moreover, contrast medium can be injected from the drainage tube, allowing the extent of the abscess cavity to be determined by fluoroscopy and CT, thereby making accurate drainage possible.     

The usefulness of CT guided drainage of abscesses caused by retained appendicoliths

OBJECTIVES: To determine the utility of percutaneous computed tomography (CT) guided drainage of abscesses formed secondary to retained appendicoliths. MATERIALS AND METHODS: A retrospective review was conducted over a 5-year period to identify patients who underwent CT guided drainage of abscesses related to retained appendicoliths. Inclusion criteria were a history of prior proven appendicitis treated by laparoscopic appendicectomy, identification of a post-operative abscess related to a visualised retained appendicolith and initial treatment by CT guided drainage. Data regarding initial technical success as well as long-term outcome was recorded in each case. RESULTS: In total, five patients were identified who underwent CT guided abscess drainage related to retained appendicoliths. There were three males and two females (age range 12-54 years). Initial drainage under CT guidance was technically successful in all cases with successful catheter placement and resolution of the abscess cavity. In all five cases however, there was recurrence of abscess formation following catheter removal. In one case, a second attempt with CT guided drainage was performed. Again this was initially successful with abscess recurrence following catheter removal. In all five cases, formal surgical drainage with removal of retained appendicolith resulted in a successful outcome. CONCLUSION: CT guided percutaneous drainage of intra abdominal abscess secondary to retained appendicoliths is only successful in the short term. Formal surgical drainage and removal of the appendicolith is required for long-term success.     

Percutaneous drainage of psoas abscess under real-time computed tomography fluoroscopic guidance

Objectives  The goal of our study was to determine the usefulness of percutaneous abscess drainage under guidance of computed tomography (CT) fluoroscopy. Materials and methods  Our subjects were 21 patients (seven women, 14 men; mean age 64 years; age range 30–87 years) who had undergone percutaneous drainage of 26 psoas abscess lesions under CT fluoroscopic guidance between May 2001 and January 2008. Drainage methods involved a needle puncture, insertion of a guidewire, serial dilations, and the exchange of the needle with a drainage tube. The procedures were guided by use of a helical CT scanner that provided real-time fluoroscopic reconstruction. Results  Percutaneous drainage under real-time CT fluoroscopic guidance was successfully performed in every procedure. Use of real-time CT fluoroscopy allowed rapid assessment of needle, guidewire, and catheter placement. No patient had serious complications related to the drainage procedure. The mean procedure time required to drain one lesion was 35.6 ± 13.6 min. Mean period after the drainage procedure until complete disappearance of the abscess as confirmed by CT was 12.4 ± 10.0 days (range 3–46 days). Conclusion  CT fluoroscopy is useful in achieving accurate and safe drainage of abnormal psoas fluid collections.     

Diagnostic imaging and interventional radiology of amebic liver abscesses. Personal experience

PURPOSE: The diagnostic imaging findings in hepatic amebiasis and the capabilities of percutaneous drainage have already been described but some debate is open on both diagnosis and treatment. We report our experience with ultrasound (US) and Computed Tomography (CT) studies of the hepatic amebic abscess and its management. MATERIAL AND METHODS: During the last 4 years we examined 14 patients with liver abscess: 11 men and 2 women; 13 were Italian and 1 African (25-61 years old, mean 36). All subjects underwent US and contrast-enhanced CT (with a conventional scanner in 12 and a helical unit in 2). The first 4 cases were also submitted to US-guided diagnostic aspiration. Six patients were treated with percutaneous drainage under US guidance using an 8-10 F pig-tail catheter which was removed 4-18 days later (mean 6). RESULTS: The abscesses were always single and uniloculated, in most cases located peripherally in the right lobe. They were large (2-11 cm, mean 7) and had round, oval, or irregular shape in 9, 3, and 2 cases respectively. US generally showed the abscess as an inhomogeneously hypoechoic mass with ill-defined walls. CT demonstrated a homogeneously hypodense collection with a thick peripheral hypodense halo; after contrast agent administration wall attenuation was increased between the edematous halo and the cavity, and an incomplete idosense ring appeared. Biphasic helical acquisitions allowed demonstration of some difference between the two vascular phases and yielded other interesting findings. Drug treatment provided complete abscess resolution in 8 patients, though in 2 it was badly tolerated. In one case no improvement was found and the patient was submitted to percutaneous drainage, which was the treatment of choice in the remaining 5 patients. The treatment was successful in all cases, but 1 patient who discontinued the combined medical therapy developed a heterotopic lesion. CONCLUSION: US and CT findings, though variable and partially different from those previously reported, may be considered sufficient for diagnostic assessment, especially if in the proper clinical and biohumoral setting. Both drug treatment and percutaneous drainage (to be considered for selected cases) are effective in the treatment of this type of abscess.
