Technical perfection is the goal of any arterial reconstruction so as to avoid postoperative complications. Experimental and clinical studies have clearly shown that these operations are imperfect and that some form of intraoperative surveillance is required to decrease the incidence of correctable technical defects. Ultrasound technology is uniquely suited for this role. This article describes the distinct advantages of duplex ultrasound for the intraoperative monitoring of vascular reconstructions.

Ultrasound-guided intraoperative liver ablation - retrospective review of indications and outcomes.
Clin Radiol
December 2024
Department of Radiology, Division of Interventional Radiology, Massachusetts General Hospital & Harvard Medical School, Boston, MA, 02114, USA. Electronic address:
Aim: To define the indications and outcomes of intraoperative ablation of hepatic malignancies.
Materials And Methods: This retrospective study comprises 27 patients (male/female: 19/8; mean age: 56 ± 13) undergoing intraoperative ablation (IOA) of liver tumours between July 2001 and August 2021 for 42 tumours, including colorectal liver metastasis (CRLM) (n = 27), hepatocellular carcinoma (HCC)(n = 14), and ovarian cancer metastasis (n = 1). The mean tumour diameter was 2.
Anterior cervical discectomy and fusion with self-locking standalone cage for the treatment of cervical degenerative disc disease in patients over 80 years.
J Orthop Traumatol

Department of Orthopaedic Surgery, Zhongshan Hospital, Fudan University, 180 Fenglin Road, Shanghai, 200032, China.
Background: The need for anterior cervical discectomy and fusion (ACDF) for cervical degenerative disc disease (CDDD) will probably grow dramatically in the geriatric population. However, ACDF with self-locking standalone cages in patients over 80 years has not yet been investigated. This study aimed to assess the clinical and radiographic results in patients over 80 years treated by ACDF with self-locking standalone cages.

Ophthalmology Department, Faculty of Medicine - Suez Canal University Hospitals, 4.5 Kilo - Ring Road, Ismailia, 41522, Egypt.
Purpose: To assess the effect of anterior chamber depth on corneal endothelium using specular microscopy following uneventful phacoemulsification among cataract patients with different axial lengths.
Methods: The study was conducted in a quasi-experimental design including 300 eyes of 300 patients with grade three age-related nuclear cataract distributed equally based on their axial length into three equal groups. All eyes had grade three nuclear cataract.

With the increasing incidence of thyroid cancer worldwide and the increasing demand for surgery, the risk of parathyroid injury is also increasing, which will lead to postoperative hypoparathyroidism (HP) and hypocalcemia. In order to improve the quality of life of patients after surgery, there is an urgent need to develop a novel platform that can identify the parathyroid gland immediately during surgery. The parathyroid gland promotes the increase of blood calcium concentration by secreting parathyroid hormone (PTH).

Division of Hepatobiliary and Pancreatic Surgery, Cancer Institute Hospital, Japanese Foundation for Cancer Research, Tokyo, Japan. Electronic address:
Background: The efficacy of local control for pancreatic cancer liver metastases (PCLM), including surgical treatment, remains controversial, with no consensus on the management and clinical significance of disappearing liver metastases (DLMs). This study aimed to evaluate the clinical implications of DLMs in treating PCLM after multi-agent chemotherapy, utilizing contrast-enhanced imaging modalities.
Methods: A retrospective analysis was conducted on patients who underwent curative resection for pancreatic cancer with synchronous or metachronous liver metastases between 2014 and 2023.
