Abstract
Aggregation-induced emission (AIE)-active micelles are a type of fluorescent functional materials that exhibit enhanced emissions in the aggregated surfactant state. They have received significant interest due to their excellent fluorescence efficiency in the aggregated state, remarkable processability, and solubility. AIE-active micelles can be designed through the self-assembly of amphipathic AIE luminogens (AIEgens) and the encapsulation of non-emissive amphipathic molecules in AIEgens. Currently, a wide range of AIE-active micelles have been constructed, with a significant increase in research interest in this area. A series of advanced techniques has been used to characterize AIE-active micelles, such as cryogenic-electron microscopy (Cryo-EM) and confocal laser scanning microscopy (CLSM). This review provides an overview of the synthesis, characterization, and applications of AIE-active micelles, especially their applications in cell and in vivo imaging, biological and organic compound sensors, anticancer drugs, gene delivery, chemotherapy, photodynamic therapy, and photocatalytic reactions, with a focus on the most recent developments. Based on the synergistic effect of micelles and AIE, it is anticipated that this review will guide the development of innovative and fascinating AIE-active micelle materials with exciting architectures and functions in the future.

Abstract
The authors present a case that highlights the anatomy of the hepatic falciform artery and describes its importance. The hepatic falciform artery is an anatomic variant that arises from the hepatic vasculature and provides arterial communication between the abdominal wall and the liver. It is essential to identify its presence, especially when surgery or embolization is planned for that area.

Laparoscopic left hepatectomy for a patient with intrahepatic cholangiocarcinoma metastasis in the falciform ligament: a case report. BMC Surg 2021; 21:122.

Abstract
Background Intrahepatic cholangiocarcinoma (ICC) is primary cancer of the liver with poor prognosis because of its high potential for recurrence and metastasis. We experienced a rare case of ICC with hematogenous metastasis to the falciform ligament. We aimed to clarify the route of metastasis to the mesentery by increasing the accuracy of preoperative imaging and establish a hepatectomy to control cancer. Case presentation
An 85-year-old woman was referred to our hospital for a detailed study of progressively increasing liver tumors. She had no subjective symptoms. Her medical history showed hypertension, aneurysm clipping for cerebral hemorrhage, and gallstones. A detailed physical examination and laboratory data evaluation included tumor markers but did not demonstrate any abnormalities. On computed tomography scan, contrast-enhanced ultrasound, and magnetic resonance imaging with gadolinium ethoxybenzyl diethylenetriamine penta-acetic acid, the tumor appeared to be located in liver segment IV, protruding outside the liver. It appeared to contain two distinct components; we suspected ICC in the intrahepatic tumor component. Laparoscopic observation revealed that the extrahepatic lesion was an intra-falciform ligament mass; laparoscopic left hepatectomy was performed. Microscopically, the main tumor in segment IV was 15 mm in diameter and was diagnosed as moderately and poorly differentiated ICC. The tumor of the intra-falciform ligament was not continuous with the main intrahepatic nodule and was also diagnosed as ICC with extensive necrosis. There were no infiltrates in the round ligament of the liver, and several tumor thrombi were found in the small veins of the falciform ligament. Conclusions To date, there have been a few reports of metastases of primary liver cancer to the falciform ligament. At the time of preoperative imaging and pathological diagnosis, this case was suggestive of considering that the malignant liver tumor might be suspected of metastasizing to the falciform ligament. Our case improves awareness of this pathology, which can be useful in the future when encountered by hepatic specialists and surgeons.

A falciform ligament flap surface sealing technique for laparoscopic and robotic-assisted liver surgery. Sci Rep 2020; 10:12143. [PMID: 32699283 PMCID: PMC7376099 DOI: 10.1038/s41598-020-69211-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2020] [Accepted: 07/08/2020] [Indexed: 11/09/2022] Open
Abstract
Whether sealing the hepatic resection surface after liver surgery decreases morbidity is still unclear. Nevertheless, various methods and materials are currently in use for this procedure. Here, we describe our experience with a simple technique using a mobilized falciform ligament flap in minimally invasive liver surgery (MILS). We retrospectively analyzed the charts from 46 patients who received minor MILS between 2011 and 2019 from the same surgical team in a university hospital setting in Germany. Twenty-four patients underwent laparoscopic liver resection, and 22 patients received robotic-assisted liver resection. Sixteen patients in the laparoscopic group and fourteen in the robotic group received a falciform ligament flap (FLF) to cover the resection surface after liver surgery. Our cohort was thus divided into two groups: laparoscopic and robotic patients with (MILS + FLF) and without an FLF (MILS-FLF). Twenty-eight patients (60.9%) in our cohort were male. The overall mean age was 56.8 years (SD 16.8). The mean operating time was 249 min in the MILS + FLF group vs. 235 min in the MILS-FLF group (p = 0.682). The mean blood loss was 301 ml in the MILS + FLF group vs. 318 ml in the MILS-FLF group (p = 0.859). Overall morbidity was 3.3% in the MILS + FLF group vs. 18.8% in the MILS-FLF group (p = 0.114). One patient in the MILS-FLF group (overall 2.2%), who underwent robotic liver surgery, developed bile leakage, but this did not occur in the MILS + FLF group. Covering the resection surface of the liver after minor minimally invasive liver resection with an FLF is a simple and cost-effective technique that does not prolong surgical time or negatively affect other perioperative parameters. In fact, it is a safe add-on step during MILS that may reduce postoperative morbidity. Further studies with larger cohorts will be needed to substantiate our proof of concept and results.

Abstract
PURPOSE To investigate the prevalence and site of origin of extrahepatic arteries originating from hepatic arteries on early phase CT during hepatic arteriography (CTHA) was accessed. Visualization of these elements on digital subtraction hepatic angiography (DSHA) was assessed using CTHA images as a gold standard. MATERIALS AND METHODS A total of 943 patients (mean age 66.9 ± 10.3 years; male/female, 619/324) underwent CTHA and DSHA. The prevalence and site of origin of extrahepatic arteries were accessed using CTHA and visualized using DSHA. RESULTS In 924 (98.0%) patients, a total of 1555 extrahepatic branches, representing eight types, were found to originate from hepatic arteries on CTHA. CTHA indicated the following extrahepatic branch prevalence rates: right gastric artery, 890 (94.4%); falciform artery, 386 (40.9%); accessory left gastric artery, 161 (17.1%); left inferior phrenic artery (IPA), 43 (4.6%); posterior superior pancreaticoduodenal artery, 33 (3.5%); dorsal pancreatic artery, 26 (2.8%); duodenal artery, 12 (1.3%); and right IPA, 4 (0.4%). In addition, 383 patients (40.6%) had at least one undetectable branch on DSHA. The sensitivity, specificity, and accuracy of visualization on DSHA were as follows: RGA, 80.0, 86.8, and 80.4%; falciform artery, 53.9, 97.7, and 80.0%; accessory LGA, 64.6, 98.6, and 92.3%; left IPA, 76.7, 99.8, and 98.7%; PSPDA, 100, 99.7, and 99.9%; dorsal pancreatic artery, 57.7, 100, and 98.8%; duodenal artery, 8.3, 99.9, and 98.7%; and right IPA, 0, 100, and 99.6%, respectively. CONCLUSION Extrahepatic arteries originating from hepatic arteries were frequently identified on CTHA images. These arteries were frequently overlooked on DSHA.

Abstract
The hepatic falciform artery (HFA) may be found in 68% of subjects in post-mortem dissections. It is well known by interventional radiologists who perform selective hepatic angiography. The reason essentially results from the potential supraumbilical skin complications which may produce by the distribution of chemotherapeutic agents through the HFA after transcatheter chemoinfusion or chemoembolization for liver tumors. Nevertheless, the spontaneous visualization of the HFA remains very unusual in current abdominal CT practice. We hereby report the demonstration of a patent HFA during conventional abdominal CT in two patients presenting without liver disease but in which very unusual variants of the gastrointestinal arteries were simultaneously found. The first patient had a common celiomesenteric trunk and the second had a severe compression of both the celiac trunk and superior mesenteric artery by the median arcuate ligament of the diaphragm. We shortly review the literature about these rare variants. We hypothesize that the HFA was spontaneously visible in our patients because of hypertrophy due supplying collateralization.

Abstract
AIM This study aimed to investigate the anatomy and mechanism of pseudolesions around falciform ligament, which appeared on dynamic contrast magnetic resonance (MR) imaging. METHODS A total of 30 cases were included in the normal control group (group 1), and 30 cases were enrolled into the liver cirrhosis group (group 2). All cases underwent MR examination including in-phase and out-phase T1-weighted image, T2-weighted fat-suppressed image, and dynamic MR imaging enhancement scanning. The MR images were analyzed to detect pseudolesions, and results from the 2 groups were compared. An ultrasound examination was also performed in all cases to assess the abdominal umbilical vein blood flow. RESULTS In group 1, MR images detected pseudolesions in 13 cases, and signal reduction did not appear in out-phase MR images compared with in-phase MR images. In 5 of these cases, the umbilical vein was observed to be connected with the hepatic IV segment, and direction flow was toward hepatic during Doppler ultrasound examination. In the 30 patients with liver cirrhosis, pseudolesions were not detected in any of the cases, dilation of the vena epigastricas was observed in 12 cases, and flow direction was from liver. The difference in the incidence of falciform ligament pseudolesions between group 1 and group 2 was statistically significant (P > 0.01). CONCLUSIONS Pseudolesions around the falciform ligament are associated with the Sappey vein, and there is no significant relationship with fatty infiltration.
