Optical coherence tomography (OCT) has been recently applied to investigate coronary artery disease in interventional cardiology. Compared to intravascular ultrasound, OCT is able to visualize various vascular structures more clearly with higher resolution. Several validation studies have shown that OCT is more accurate in evaluating neointimal tissue after coronary stent implantation than intravascular ultrasound. Novel findings on OCT evaluation include the detection of strut coverage and the characterization of neointimal tissue in an in-vivo setting. In a previous study, neointimal healing of stent strut was pathologically the most important factor associated with stent thrombosis, a fatal complication, in patients treated with drug-eluting stent (DES). Recently, OCT-defined coverage of a stent strut was proposed to be related with clinical safety in DES-treated patients. Neoatherosclerosis is an atheromatous change of neointimal tissue within the stented segment. Clinical studies using OCT revealed neoatherosclerosis contributed to late-phase luminal narrowing after stent implantation. Like de novo native coronary lesions, the clinical presentation of OCT-derived neoatherosclerosis varied from stable angina to acute coronary syndrome including late stent thrombosis. Thus, early identification of neoatherosclerosis with OCT may predict clinical deterioration in patients treated with coronary stent. Additionally, intravascular OCT evaluation provides additive information about the performance of coronary stent. In the near future, new advances in OCT technology will help reduce complications with stent therapy and accelerating in the study of interventional cardiology.

BACKGROUND: It has been suggested digital mucous cysts (DMCs) are associated with osteoarthritis and osteophytes in the elderly, and usually have a communicating pedicle with the joint. Surgical excision is a standard therapy with a high cure rate. OBJECTIVE: The purpose of this prospective study is to evaluate the features of DMCs via clinical, radiological and pathological examination and the efficacy of surgical excision of DMCs. METHODS: Between 2010 and 2014, 24 Korean patients were treated with the resection of the cyst and the pedicle. Preoperative X-ray and ultrasonography were performed to detect the presence of the osteophyte and the connection to the joint space. Postoperative patients' satisfaction score was assessed by the visual analogue scale (0~10). RESULTS: The osteophytes were found in 15.8%. In ultrasonographic findings, there were prominent flow signals between the cyst and the joint space in 13.6%. There were no serious postoperative complications, and recurrences were observed in 16.7%. Mean postoperative satisfaction score was 8.3. CONCLUSION: It seems that preoperative X-ray for osteophytes and ultrasonographic study for connection are not always helpful for the treatment of DMCs, and that the surgical excision with a pedicle ligation and electrocoagulation is an effective treatment modality.

Various complications following laparoscopic cholecystectomy have been reported. We describe a case of intraabdominal abscess formation which was developed two months after the inadvertently spilling of gallstones laparoscopic cholecystectomy in a patient with acute cholelithiasis. The condition was initially found on computed tomography and the diagnosis was confirmed with ultrasound. Although this is a rare complication of laparoscopic cholecystectomy, the spilling of gallstones should be recognized as a potential source of intra-abdominal abscess formation even in a patient presenting months after laparoscopic cholecystectomy. We suggest that routine use of the specimen retrieval bag is highly recommended especially for beginners of laparoscopic cholecystectomy during their initial learning period.

PURPOSE: This study evaluated whether the axial length of the fellow eye measured by A-scan biometry can be utilized for selecting the proper size of the orbital implant. METHODS: Thirty four eyes of 34 adult patients who had undergone eviscerations between March 2000 and May 2002 were included. We measured the axial length of the fellow eyes by A-scan preoperatively. Postoperatively, the central thickness and volume of ocular prosthesis were measured to determine the ideal size of prosthesis. RESULTS: Average diameter of the fellow eyes was 22.6mm. Average difference in diameter between the fellow eyes and orbital implants was 1.8mm among eyes with 20-22 mm in adults, and 3.8mm among eyes with 22-24mm. Average central thickness of the ocular prosthesis was 6.47 mm, and average volume was 2.2 ml. Complications occurred in 4 cases, and 2 of those cases were corrected by operations. CONCLUSIONS: Preoperative measurement of the diameter of the fellow eye using A-scan ultrasonography can be useful in selecting the size of the orbital implant before evisceration in adult patients. It also helped the selection of the proper sized ocular prosthesis and the prevention of many postoperative complications.

PURPOSE: The purpose of this study was to evaluate the relative utility and benefits of free-hand 2-dimensional intraoperative ultrasound (FUS) and navigated 3-dimensional intraoperative ultrasound (NUS) as ultrasound-guided biopsy (USGB) techniques for supratentorial lesions. METHODS: All patients who underwent USGB for suspected supratentorial tumours from January 2008 to December 2017 were retrospectively analyzed. The charts and electronic medical records of these patients were studied. Demographic, surgical, and pathological variables were collected and analyzed. The study group consisted of patients who underwent either FUS or NUS for biopsy. RESULTS: A total of 125 patients (112 adults and 13 children) underwent USGB during the study period (89 FUS and 36 NUS). NUS was used more often for deep-seated lesions (58% vs. 18% for FUS, P<0.001). The mean operating time for NUS was longer than for FUS (156 minutes vs. 124 minutes, P=0.001). Representative yield was found in 97.7% of biopsies using FUS and in 100% of biopsies using NUS (diagnostic yield, 93.6% and 91.3%, respectively). The majority of lesions (89%) were high-grade gliomas or lymphomas. Postoperative complications were more common in the NUS group (8.3% vs. 1.2%), but were related to the tumour location (deep). CONCLUSION: Despite the longer operating time and higher rate of postoperative complications, NUS has the benefit of being suitable for biopsies of deep-seated supratentorial lesions, while FUS remains valuable for superficial lesions.

9.Advances of Diaphragm Ultrasound in Anesthesia Management.
Acta Academiae Medicinae Sinicae 2022;44(5):891-898
Diaphragm excursion,diaphragm thickness,and diaphragmatic thickening fraction are three indicators for evaluating the two hemidiaphragms by ultrasound.Diaphragm ultrasound has been widely applied in clinical practice including anesthesia management.It can help to diagnose postoperative residual curarisation and identify patients at a high risk of suffering from postoperative pulmonary complications.It can serve to recognize patients with diaphragm paralysis due to surgical or anesthetic factors as early as possible.Moreover,diaphragm ultrasound plays a role in preoperative pulmonary function assessment for special sufferers with chronic obstructive pulmonary disease,adolescent idiopathic scoliosis,or neuromuscular disease.Apart from these,diaphragm ultrasound can give anesthesiologists and colleagues in intensive care unit an important clue for extubation and weaning from mechanical ventilation of patients.

10.Research on Shielding of Emboli with the Phase-Controlled Ultrasound.
Chinese Journal of Medical Instrumentation 2016;40(1):1-4
The postoperative neurological complications is associated with intraoperative cerebral emboli, which results from extracorporeal circulation and operation. It can effectively reduce the incidence of neurological complications with ultrasonic radiation. In fluids, a particle will change it's motion trail when it is acted by the radiation force generated by the ultrasound. This article mainly discuss how to shielding emboli with ultrasound. The equipment can transmit phased ultrasonic signals, which is designed on a FPGA development board. The board can generate a square wave, which is converted into a sine wave through a power amplifier. In addition, the control software has been developed on Qt development environment. The result indicates it's feasible to shielding emboli with ultrasonic radiation force. This article builds a strong foundation for the future research.
