CT for Evaluation of Hemoptysis.
Radiographics
November 2021
Article Synopsis
- Hemoptysis is the coughing up of blood, which is a serious clinical symptom that requires careful diagnosis through various methods, with CT scans being the preferred noninvasive tool.
- The process of interpreting CT scans for hemoptysis involves identifying hemorrhage in the lungs and determining whether the bleeding has a specific vascular source, as hemoptysis can arise from both primary and secondary vascular causes.
- Understanding these vascular mechanisms is crucial for radiologists to accurately diagnose the underlying issues leading to hemoptysis and to guide appropriate treatment decisions.
Purpose: To report outcomes of percutaneous cholecystostomy (PC) catheter placement in patients with acute cholecystitis (AC) and propose management algorithm of AC after PC catheter placement based on the outcomes.
Method And Materials: Retrospective study was performed. 419 patients who underwent PC between July 2010 and September 2016 were included.
The morbidity and mortality of cholecystectomy can increase to 10% in high surgical risk patients. The technique for percutaneous cholecystolithotomy consists of 3 steps: (1) percutaneous cholecystostomy, (2) tract dilation and cholecystolithotomy, and (3) tract evaluation and catheter removal. Cholecystoscopy is critical in guiding the lithotripsy probe for fragmentation of large stones and is useful for locating small stone fragments not seen in cholangiography.

Materials And Methods: Between 2002 and 2011, six patients (mean age, 41.7 years; range, 23-65 years) with SMA pseudoaneurysms were treated percutaneously with the placement of covered stents at our institution.
Bile duct injuries are infrequent but potentially devastating complications of biliary tract surgery and have become more common since the introduction of laparoscopic cholecystectomy. The successful management of these injuries depends on the injury type, the timing of its recognition, the presence of complicating factors, the condition of the patient, and the availability of an experienced hepatobiliary surgeon. Bile duct injuries may lead to bile leakage, intraabdominal abscesses, cholangitis, and secondary biliary cirrhosis due to chronic strictures.

Materials And Methods: A patient underwent elective laparoscopic cholecystectomy for symptomatic cholelithiasis.
Background: The Hepp-Couinaud technique describes side-to-side HJ to the main left hepatic duct but a side-to-side approach is not consistently used when repairing other ducts. Compared with end-to-side repairs, side-to-side anastomoses require less dissection, theoretically preserving blood supply to the bile ducts, and usually permit wider anastomoses.
Methods: We report the treatment results of 113 consecutive biliary injuries, with intention to perform side-to side anastomosis in all.
