Birt-Hogg-Dubé syndrome in apparent primary spontaneous pneumothorax patients; results and recommendations for clinical practice.

Background: Birt-Hogg-Dubé syndrome (BHD) is an inherited disease caused by pathogenic variants in the FLCN gene. One of the characteristics is the increased risk for spontaneous pneumothorax, likely due to the presence of pulmonary cysts mainly distributed under the carina. Due to variable expression and lack of awareness, BHD is likely to be underdiagnosed.

Transcatheter CT hepatic arteriography-guided percutaneous ablation to treat ablation site recurrences of colorectal liver metastases: the incomplete ring sign.

Transcatheter computed tomography (CT) arterial portography-guided percutaneous liver tumor ablation has been proved to be feasible and accurate in treating liver metastases from colorectal origin that are obscure on ultrasound and unenhanced CT. However, distinguishing local recurrence from scars after ablation can still be difficult. This report describes nine patients with recurrences after ablation in whom transcatheter CT hepatic arteriography allowed differentiation of recurring and residual tumor tissue (incomplete ring enhancing lesion) from tumor-free nonenhancing scars.

[A splenic arteriovenous fistula].

Background: Splenic arteriovenous fistula is a rare entity which can present as portal hypertension and related symptoms.

Case Description: A 60-year-old female attended the emergency department with haematemesis. She had microcytic anaemia and was admitted to the Gastroenterology and Hepatology Department.

Compromised visceral circulation does not affect the outcome of colorectal surgery.

Purpose: Anastomotic leakage is a serious complication after colorectal surgery, and many risk factors for this problem have so far been identified. The aim of this study was to assess the association between visceral arterial occlusive disease and anastomotic leakage.

Methods: The preoperative abdominal computed tomography scans from all consecutive patients who underwent colorectal surgery with anastomosis in 2010 were retrospectively analyzed.

[Periaortitis following endovascular aortic repair].

Background: Infection is the most obvious cause of fever following implantation of an endovascular prosthesis; however, fever and inflammation around the arterial wall can also be caused by a sterile inflammatory reaction: periaortitis.

Case Study: An 81-year-old man was referred because of fever and back pain. He had undergone an endovascular aortic repair (EVAR) 1 year earlier; an endovascular prosthesis had been placed during this procedure, to repair an abdominal aortic aneurysm.
