Here we present a 46-yr-old man with recurrent syncopal episodes thought to be of cardiac origin. He was eventually found to harbor a giant, partially thrombosed, saccular aneurysm arising from the A1/A2 segment of the right anterior cerebral artery with foramen of Monro obstruction and a trapped left-sided ventricular system. An azygous left A2 artery segment supplied both callosomarginal arteries. We performed an in situ side-to-side anastomosis between the distal left azygous anterior cerebral artery and the right pericallosal artery, which was previously supplied by the right A1...

PURPOSE: We hypothesized that osteoarthritis developing after instability surgery is radiographically similar to primary arthritis and that arthroplasty provides comparable outcomes in patients with these two types of osteoarthritis. METHODS: Patients with osteoarthritis due to instability surgery (group I) and with primary osteoarthritis (group II) were included. Mean follow-up was 52.6 and 41.6 months, respectively. Hemiarthroplasties (HA) were 32% in group I and 27% in group II; total shoulder arthroplasties (TSA) were 68 and 73% respectively...

Objective: To analyze the prognosis of Ⅰb2 and Ⅱa2 cervical squamous cancer without high risk factors treated with neo-adjuvant chemotherapy (NACT) and radical hysterectomy. Methods: This retrospective study included patients with International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ b2 and Ⅱ a2 cervical squamous cancer without high risk factors who underwent platinum-based NACT followed by radical surgery from January 2008 to January 2015. The responses of NACT were observed and compared in their effect on postoperative pathologic risk factors...

Objective: To introduce the laparoscopic type C1 hysterectomy based on the anatomic landmark of the uterus deep vein and its branched and to evaluate its feasibility and safety for cervical cancer and its effect to bladder function and to provide some reference to simplify the surgical procedures of laparoscopic type C1 hysterectomy. Methods: The clinicopathologic data of the patients with stage ⅠA2~ⅡB cervical cancer and who underwent the laparoscopic C1 hysterectomy based on anatomic landmark of the uterus deep vein and its branches between March 2010 and December 2015 was retrospectively analysed...

Aim of the study: To assess the quality of life in patients treated for breast cancer who were 5 years after diagnosis and were active members of Breast Cancer Self-Help Groups. Material and methods: The study had a non-randomized, cross-sectional design. We enrolled 167 women who were more than 5 years after mastectomy and were active members of Breast Cancer Self-Help Groups (group A1). As a control group we enrolled 117 women after mastectomy - not members of such support groups (group A2)...

This article reviews some recent advancements in repair and rehabilitation of the flexor tendons. These include placing sparse or no peripheral suture when the core suture is strong and sufficiently tensioned, allowing the repair site to be slightly bulky, aggressively releasing the pulleys (including the entire A2 pulley or both the A3 and A4 pulleys when necessary), placing a shorter splint with less restricted wrist positioning, and allowing out-of-splint active motion. The reported outcomes have been favourable with few or no repair ruptures and no function-disturbing tendon bowstringing...

BACKGROUND: Smoking cessation had been typically associated with weight gain. We have reported that there is no relationship between tobacco use and weight loss after bariatric surgery in the short term. The objective of this study was to establish the relationship between weight loss and the smoking habit in patients undergoing bariatric surgery and to analyze weight loss on severe smokers and on those patients who stopped smoking during the long-term postoperative period. METHODS: One hundred eighty-four patients included in our previous study were contacted by phone at 7 years after sleeve gastrectomy...

Pancreatic cancer has a high mortality rate due to late diagnosis and the tendency to invade surrounding tissues and metastasize at an early stage. A molecular imaging agent that enables both pre-surgery antigen-specific positron emission tomography (immunoPET) and intra-operative near-infrared fluorescent (NIRF)-guidance could benefit diagnosis, staging and surgical resection of pancreatic cancer, which remains the only curative treatment. Methods: A dually labeled probe was developed based on A2 cys-diabody (A2cDb) targeting the cell surface antigen prostate stem cell antigen (PSCA) that is expressed in a majority of pancreatic cancers...

New developments in primary tendon repair over the past decades include stronger core tendon repair techniques, judicious and adequate venting of critical pulleys, followed by a combination of passive and active digital flexion and extension. During repair, core sutures over the tendon should have sufficient suture purchase (no shorter than 0.7 to 1 cm) in each tendon end and must be sufficiently tensioned to resist loosening, forming gaps. Slight or even modest bulkiness in the tendon substance at the repair site is not harmful, though marked bulkiness should always be avoided...

BACKGROUND: It was thought that the AO types A1.2 and A1.3 fractures are rotationally stable; however, it revealed instability when fixed using the dynamic hip screw. Therefore, we hypothesized that these fractures should be treated as rotationally unstable. METHODS: A series of 83 fractures of the AO types A1, A2, and B2.1 were treated using dynamic hip screw with derotation screw (DHS/DRS) composite and then prospectively followed for 24 months. Adequacy of reduction and fixation were immediately assessed after surgery, and fracture collapse was assessed at six months or when fractures healed...

Around one third of humeral fractures and 2-6% of all fractures occur to the distal part of the humerus. There is a bimodal distribution differentiating between young male patients with high-energy and elderly female patients with low-energy trauma related to osteoporosis. The AO classification and Dubberley subclassification are used in daily routine. Most fractures are diagnosed on radiographs. For further evaluation, three-dimensional computed tomography is recommended, especially for comminuted or complex fractures...

Introduction: The treatment of femoral diaphyseal fractures by intramedullary nailing has become a common procedure in orthopaedic surgery. The purpose of this numerical simulation was to present how the changes in configuration of the stabilisation system can affect the stress and displacement state in the bone tissue and implanted device. Material and Methods: The numerical comparison of the stabilisation variants for the type 32-A2 femoral diaphyseal fracture (according to the AO classification) performed by using the Charfix2 (ChM®) anatomical nail locked in a number of chosen ways...

Successful mitral valve (MV) repair for degenerative mitral regurgitation (DMR) is mainly related to surgical expertise and MV anatomy. Although 2D echocardiography, specifically transoesophageal (TOE), provides precise information regarding MV anatomy, recent advancements in matrix technology meant a decisive step forward to the point where segmental MV analysis can be accurately performed from a noninvasive 3D transthoracic (TTE) approach. The aims of this study were: (a) to evaluate the feasibility and time required for real-time 3D TTE in a large consecutive cohort of patients with severe DMR in the assessment of MV anatomy; (b) to compare the accuracy of 3D TTE and 2D TOE versus surgical inspection in the recognition and localization of all components of the MV leaflets; (c) to establish the added diagnostic value of 3D colourDoppler examination to pure 3D morphologic evaluation...

We report outcomes in 29 patients with flexor tendon repairs in 32 digits (five thumbs and 27 fingers) with our modified protocols. We repaired the lacerated flexor digitorum profundus tendons with core suture repairs using the 6-strand M-Tang method and without circumferential sutures. We divided the pulleys as much as needed to allow excursion of the repaired tendons, including complete division of the A4 or A2 pulleys when necessary. In nine fingers, we repaired one slip of the flexor digitorum superficialis tendon and resected the other half...
