We assess the theoretical feasibility of percutaneous posterior sacral foramen (pSF) needle puncture of the sacral dural sac (DS) by studying the three-dimensional imaging anatomy of pSFs relative to the sacral canal (SC). On CT images of 40 healthy subjects, we retrospectively studied sacral alae passageways from SC to pSFs in all three planes to determine if an imaginary spinal needle could theoretically traverse S1 or S2 pSFs in a straight path toward DS. If not straight, we measured multiplane angulations and morphometrics of this route. We found no straight connections between S1 or S2 pSFs and SC. Instead, there were bilateral spatially complex dorsoventral M-shaped "foraminal conduits" (FCs; common, ventral, and dorsal) from SC to anterior SFs and pSFs that would prevent percutaneous straight needle puncture of the DS. This detailed knowledge of the sacral FCs will be useful for accurate imaging interpretation and interventional procedures on the sacrum.

A male fetus at 20 weeks of gestation presented with severe bilateral hydroureteronephrosis and distended bladder due to a large ureterocele. A percutaneous ureterocele puncture at 21+3 weeks aimed to decompress the ureterocele, unclog the lower urinary tract, and prevent renal damage. Post-puncture, the ureterocele decompressed, with improved left hydronephrosis and a normal right kidney.

Hepatocellular carcinoma (HCC) is an aggressive disease with poor prognosis, necessitating preclinical models for evaluating novel therapies. Large animal models are particularly valuable for assessing locoregional therapies, which are widely employed across HCC stages. This study aimed to develop a large animal HCC model with tailored tumor mutations.

Background: Over the past few decades, percutaneous sclerotherapy has been proven to be efficacy in treating macrocystic lymphatic malformations (LMs). Unfortunately, there still remains challenging in the treatment of microcystic LMs given their size. We introduce the intralesional laser thermolysis (ILT) technique, a novel enhancement technique for the traditional percutaneous sclerotherapy in the treatment of microcystic LMs.

Emphysematous polycystic renal infection (EPRI) has a poor prognosis with conservative management, and early surgical nephrectomy has been recommended. However, percutaneous cyst drainage may be a possible treatment option. We experienced 6 patients with autosomal dominant polycystic kidney disease (ADPKD) presenting with EPRI.

Aims: This study aims to verify the feasibility and safety of percutaneous coronary intervention (PCI) after a distal transradial approach (dTRA) with radial artery occlusion (RAO) recanalization.
Methods: Between July 2018 and January 2022, 30 patients underwent PCI following attempted RAO recanalization via dTRA. Among these cases, the target radial arteries could not be recanalized in five patients, necessitating alternative vascular access.
