Congenital portosystemic venous shunts are developmental anomalies. They represent portal communication with the systemic circulation. The pathogenesis is linked to the complexity of the embryological development of the inferior vena cava and portal vein.

Percutaneous cholecystostomy for high-risk patients with acute cholangitis.

Percutaneous cholecystostomy (PC) is a well-established treatment for acute cholecystitis. We investigate the performance and role of PC in managing acute cholangitis.Retrospective review on all patients who underwent PC for acute cholangitis between January 2012 and June 2017 at a major regional hospital in Hong Kong.

Percutaneous radiofrequency ablation versus surgical radiofrequency ablation for malignant liver tumours: the long-term results.

Background: Radiofrequency ablation (RFA) has been used to treat hepatocellular carcinoma (HCC) and liver metastases for more than 10 years with promising early outcomes. Preliminary results comparing percutaneous and surgical approaches have shown no difference in short-term outcomes. In this study, the longer-term outcomes were presented.

Radiofrequency ablation for benign aldosterone-producing adenoma: a scarless technique to an old disease.

Objective: To evaluate the safety and efficacy of radiofrequency ablation (RFA) in treating primary aldosteronism (PA) due to aldosterone-producing adenoma (APA).

Background: Radiofrequency ablation is an established technique for treating malignant solid organ neoplasm. Its application on benign functional adrenal adenoma has never been prospectively described.

Revascularization for post-transplant renal artery stenosis.

Background: Percutaneous transluminal angioplasty has now been increasingly accepted as a primary treatment option for transplant renal artery stenosis.

Methods: This single-centre study evaluated the treatment effect of percutaneous transluminal angioplasty as primary intervention among 18 consecutive patients with angiographically demonstrated transplant renal artery stenosis.

Results: Patients (14 men and 4 women, mean age 49 +/- 9 years) were followed up for a mean duration of 21.
