BACKGROUND: Radial/oblique tears of the midbody of the lateral meniscus significantly impair the ability of the meniscus to withstand the tibiofemoral load, requiring meniscal repair. However, healing status after meniscal repair has not been fully elucidated. This study aimed to evaluate arthroscopic findings after inside-out suture repair for isolated radial/oblique tears of the midbody of the lateral meniscus. METHODS: From 2011 to 2015, 18 consecutive patients with isolated radial/oblique tears of the midbody of the lateral meniscus underwent arthroscopic inside-out repair with the tie-grip suture technique...

Mesenchymal stem cells (MSCs) are attractive tools for regenerative medicine because of their multi-differentiation potential and immunomodulation capacity. In congenital heart defect surgical correction, replacement grafts lacking growth potential are commonly used. Tissue engineering promises to overcome the limitations of these grafts. In this study, we hypothesized that human thymus derived MSCs are a suitable tool to tissue engineer a living vascular graft with good integration and patency once implanted in vivo...

BACKGROUND: Fat grafting is a commonly performed procedure not only for augmenting the soft tissue but also for regeneration in esthetic and reconstructive plastic surgery.However, unpredictable fat survival rate because of high resorption rate is remained as the main problem. The purpose of this study was to investigate the effect of pretreatment of the recipient site to the fat survival using fractional carbon dioxide (CO2) laser. METHODS: The rats were divided to 2 groups...

Transcatheter aortic valve replacement (TAVR) is a safe and effective therapy for aortic valve replacement in patients ineligible for or at high risk for surgery. However, outcomes after TAVR based on an individual's sex remain to be fully elucidated. We searched PUBMED and EMBASE using the keywords: 'transcatheter aortic valve replacement', 'transcatheter aortic valve implantation', 'sex differences', 'gender', 'sex characteristics' and collected information on baseline features, procedural characteristics and post-procedural outcomes in women...

OBJECTIVE A postoperative visual field defect resulting from damage to the occipital lobe during surgery is a unique complication of the occipital transtentorial approach. Though the association between patient position and this complication is well investigated, preventing the complication remains a challenge. To define the area of the occipital lobe in which retraction is least harmful, the surface anatomy of the brain, course of the optic radiations, and microsurgical anatomy of the occipital transtentorial approach were examined...

Vascular xenografts are widely used in cardiovascular surgery as an alternative to autologous vessels and vascular allografts. Calcification is one of the main drawbacks of vascular grafts, especially among young patients and children. Among different anticalcification approaches, chitosan emerges as a highly promising candidate due to its versatility, natural origin, and biocompatibility. We investigated the anticalcification efficacy of globular chitosan ("Chitozol") as it demonstrated the improved rate of water solubility as compared with conventional linear macromolecules of chitosan...

OBJECTIVES: To develop a model for predicting long-term survival following coronary artery bypass graft surgery. METHODS: This study included 46 573 patients from the Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZCTS) registry, who underwent isolated coronary artery bypass graft surgery between 2001 and 2014. Data were randomly split into development (23 282) and validation (23 291) samples. Cox regression models were fitted separately, using the important preoperative variables, for 4 'time intervals' (31-90 days, 91-365 days, 1-3 years and >3 years), with optimal predictors selected using the bootstrap bagging technique...

Importance: Ensuring that patients undergo surveillance imaging after surgery is a key quality metric after many vascular procedures. It is unclear whether hospital participation in a national quality improvement registry such as the Vascular Quality Initiative (VQI) achieves this goal. Objective: To determine if hospital participation in the VQI registry is associated with increased rates of surveillance imaging after vascular procedures. Design, Setting, and Participants: A quasi-experimental study used Medicare claims to study 2174 US hospitals in which 1 530 102 patients had undergone an endovascular abdominal aortic aneurysm repair (EVAR), 1 403 067 patients had undergone a lower extremity bypass (LEB) or peripheral vascular intervention (PVI), and 294 942 patients had undergone carotid endarterectomy (CEA) and carotid artery stenting (CAS) procedures between January 1, 2007, and December 31, 2012...

OBJECTIVES: Segmentectomy by video-assisted thoracoscopic surgery (VATS) permits anatomical resection for diagnosis and treatment of small lung nodules but requires that intersegmental planes and segmental vessels be identified accurately. Near-infrared angiography with systemic injection of indocyanine green (ICG) can precisely identify the intersegmental plane. The purpose of this study was to confirm the usefulness of ICG angiography during VATS segmentectomy. METHODS: We retrospectively reviewed the records of 22 consecutive patients who underwent VATS segmentectomy performed with near-infrared angiography between November 2014 and October 2015...

BACKGROUND: The success of stellate ganglion block (SGB) is traditionally determined on the basis of findings such as Horner's syndrome, temperature rise in the face, hyperemia of the tympanic membrane, and nasal congestion. However, decreases in vascular resistance and increases in blood flow in the arm may be more meaningful findings. To date, the effect of SGB on the regional hemodynamics of the arm has not been evaluated using pulsed-wave Doppler ultrasound. METHODS: A total of 52 patients who were to undergo orthopedic surgery of the forearm were randomly assigned to either the mepivacaine group (SGB with 5 mL of 0...

Bladder reconstruction remains challenging for urological surgery due to lack of suitable regenerative scaffolds. In a previous study, we had used a collagen-binding basic fibroblast growth factor (CBD-bFGF) to bind bFGF to the collagen scaffold, which could promote bladder regeneration in rats. However, the limited graft size in rodent models cannot provide enough evidence to demonstrate the repair capabilities of this method for severely damaged bladders in humans or large animals. In this study, the CBD-bFGF was used to activate a bladder acellular matrix (BAM) scaffold, and the CBD-bFGF/BAM functional scaffold was assessed in a canine model with a large segment defect (half of the entire bladder was resected)...

Introduction The impact of the introduction of video assisted thoracoscopic surgery (VATS) on the management of lung cancer 20 years ago has been well documented. However, the uptake of VATS lobectomy in surgical practice worldwide has been slower than expected. We believe that this is partly due to a lack of consensus on how this procedure should be integrated into training programmes. We present our initial experience with a newly developed training model, which could help bridge the divide between open and VATS lobectomy...

Basic fibroblast growth factor (bFGF), a known angiogenic factor, may provide a potential strategy for the treatment of myocardial infarction (MI), but it is limited by a relatively short half-life. Dex-PCL-HEMA/PNIPAAm hydrogel provides a reservoir for the controlled release of growth factors. The aim of the current study was to evaluate the effects of bFGF incorporated into a Dex-PCL-HEMA/PNIPAAm hydrogel on angiogenesis and cardiac health in a rat model of acute MI, induced by coronary artery ligation. Phosphate-buffered solution (PBS group), Dex-PCL-HEMA/PNIPAAm hydrogel (Gel group), bFGF in phosphate-buffered solution (bFGF group) or bFGF in hydrogel (Gel + bFGF group) was injected into a peri-infarcted area of cardiac tissue immediately following MI...

Pituicytomas are rare low-grade glial lesions of neurohypophysis or adenohypophysis. They are often misdiagnosed as adenomas due to their similar morphology. Previous reports have underlined their non specific aspect. In our experience, presence of flow voids on MR, which usually indicate hypervascularized tumors with strong arterial supply, may be a useful sign to identify pituicytomas. Unlike adenomas, pituicytomas are highly vascularized tumors. Second, we emphasize the strong enhancement of these tumors when compared to normal hypophysis, which may be another sign of the their hypervascularization...
