One of the principles of managing trauma patients is that of their continuous re-evaluation over the hours and days. Even if the execution of the computed tomography method is classically recommended, especially in the most serious cases and in polytraumas with major dynamics, the clinician can use or request an ultrasound examination, especially in subsequent re-evaluations. Here we report a clinical case demonstrating how an ultrasound re-evaluation after the acute event can lead to a correct diagnosis of a rare complication of thoracic trauma...

We evaluated the feasibility of harvesting bilateral internal thoracic arteries with the da Vinci SP through a single left sided subcostal incision. Complete bilateral mobilization with sufficiently long conduits for multivessel grafting was possible in two human cadavers and two live porcine. Creating the subcostal access and docking the SP system took between 14 to 21 min and total harvest time ranged from 65 to 125 minutes in all models. No major bleeding was observed in the live porcine and hemostasis managed with the available instrumentation...

OBJECTIVE: This study determined hazard factors and long-term survival rate of total arterial coronary artery bypass graft surgery over 20 years in an extensively large, population-based cohort. METHODS: A total of 2979 patients who underwent isolated CABG from April 1999 to March 2020 were studied in 4 groups- Group-A (bilateral internal mammary artery ± radial artery), Group-B (single internal mammary artery + radial artery ± saphenous vein), Group-C (single internal mammary artery ± saphenous vein; no radial artery), and Group-D (radial artery ± saphenous vein; no internal mammary artery)...

BACKGROUND: Sparsity of recipient vessels poses a challenge for microsurgical free flap reconstruction of sternal defects following deep sternal wound infection after cardiac surgery. METHODS: From January 2013, a standardized algorithm for dealing with sparse recipient vessels was strictly followed. In this retrospective study including 75 patients, we compared operative details, surgical complications, and reconstructive outcomes of patients treated according to this algorithm (group A: January 2013-May 2021; n = 46) with a historical control group (group B: January 2000-December 2012, n = 29)...

To determine whether deep inspiratory breath-hold (DIBH) reduces dose to organs-at-risk (OAR), in particular the right coronary artery (RCA), in women with breast cancer requiring right-sided post-mastectomy radiotherapy (PMRT) including internal mammary chain (+IMC) radiotherapy (RT). Fourteen consecutive women requiring right-sided PMRT + IMC were retrospectively identified. Nodal delineation was in accordance with European Society for Radiology and Oncology (ESTRO) guidelines and tangential chest wall fields marked...

BACKGROUND: Deep sternal wound infection (DSWI) remains a serious complication after coronary artery bypass grafting (CABG). We herein aimed to stratify diabetic patients who underwent CABG using bilateral internal mammary artery (BIMA) for levels of glycated hemoglobin A1C (HbA1c) and compare postoperative outcomes. METHODS: Between January 2010 and August 2020, 4,186 consecutive patients underwent isolated CABG at our center. In 3,229 patients, preoperative HbA1c levels were available...

CD40L-CD40-TRAF signaling plays a role in atherosclerosis progression and affects the pathogenesis of coronary heart disease (CHD). We tested the hypothesis that CD40L-CD40-TRAF signaling is a potential therapeutic target in hyperlipidemia, diabetes, and hypertension. In mouse models of hyperlipidemia plus diabetes (db/db mice) or hypertension (1 mg/kg/d angiotensin-II for 7 days), TRAF6 inhibitor treatment (2.5 mg/kg/d for 7 or 14 days) normalized markers of oxidative stress and inflammation...

Postoperative sensitivity of the nipple-areola complex (NAC) is an important concern for women after reduction mammoplasty. Previous studies have demonstrated that sensory branches of the fifth anterior intercostal nerve are important for innervating the NAC and that using an inferior pedicle technique is associated with improved sensory retention. The significance of this case report is that it demonstrates the importance of the fifth anterior intercostal sensory nerve branches using a prototype fluorescent imaging camera...

Free-flap reconstruction for recurrence of head-and-neck cancer with vessel depletion is a technical challenge, and the literature is sparse. The present technical note describes the key-points of an approach harvesting the internal mammary pedicle. Results are reported in 3 patients, and pros and cons are discussed.

BACKGROUND: Microvascular visualization is crucial in understanding the mechanisms of several pathologies. For instance, visualization of the tumor microenvironment is important in understanding angiogenesis and role in cancer progression. Visualization would provide insights to cancer diagnosis, predicting metastatic growth, and evaluating therapeutic protocols. Similarly, understanding the microvascular network could be beneficial for study of degenerative diseases and tissue repair...

BACKGROUND: Free tissue transfer is often required for the reconstruction of complex and deep anterior chest wall wounds, for which the identification of suitable recipient vessels is crucial. Although the internal mammary arteries (IMAs) are a representative option, identifying secondary options when these vessels are compromised remains a challenge. This report evaluated the efficacy of using the thoracoacromial vessels (TAVs) as recipients for chest wall reconstruction by reviewing our experience...

Abdominal-based free flaps are the mainstay of autologous breast reconstruction; however, the region may not be ideal for patients with inadequate soft tissue or history of abdominal surgery. This case describes the use of a novel conjoined flap based on the profunda artery perforator and upper gracilis pedicles, named the perforator and upper gracilis (PUG) flap. This flap design aims to maximize medial thigh flap volume while ensuring robust tissue perforation. Here, we present our experience with the PUG flap in a breast cancer patient undergoing autologous reconstruction...

OBJECTIVE AND DESIGN: A single-center prospective randomized controlled study was conducted to assess the effect of targeted mild hypercapnia (TMH) on cerebral oxygen saturation (rSO2 ) in patients undergoing off-pump coronary artery bypass grafting (CABG). SETTING AND PARTICIPANTS: A prospective randomized controlled study involving 100 patients undergoing off-pump CABG at U. N. Mehta Hospital, Ahmedabad, Gujarat, India. INTERVENTION: Patients were randomized to either the TMH (PaCO2 45-55 mmHg) or the targeted normocapnia (TN; PaCO2 35-45 mmHg) group, containing 50 patients in each group...

BACKGROUND: Epidemiological investigations suggest that patients with heart failure have a higher incidence of cancer; however, the causal role of cardiac disease on cancer progression remains unclear. OBJECTIVES: This study aimed to investigate the impact and underlying mechanisms of myocardial infarction (MI)-induced heart failure on tumor cell growth. METHODS: We generated a syngeneic mouse model by implanting mammary tumor-derived 4T1 cells into BALB/c mice with MI resulting from ligation of the left anterior descending artery...

OBJECTIVE: The effect of one-inflow and two-inflow coronary surgical revascularization techniques inclosing skeletonized double mammary artery (BIMA) as T-graft on outcome is studied. METHODS: Early ad mid-term outcome of complete BIMA revascularization (C-T-BIMA) versus left-sided BIMA with right-sided aorto-coronary bypass (L-T-BIMA + R-CABG) is quantified and analyzed by multivariate logistic regression, Cox-regression, and Kaplan-Meier analysis in a series of 204 consecutive patients treated for triple-vessel coronary disease (3v-CAD)...

BACKGROUND AND AIM: The biological behaviour of coronary graft conduits over time may be considered by serial angiography. METHODS: A single institution retrospective cohort received mostly clinically indicated angiography between 1997 and 2020, following coronary bypass surgery. Only perfectly patent grafts (absence of any lumen irregularity) for each conduit type at the first postoperative angiogram were selected for a later comparison. The latest angiograms were at least 5 years postoperatively, and at least 1 year after first postoperative angiogram...

BACKGROUND: Data on female gender differences on clinical prognosis after coronary artery bypass grafting (CABG) are still controversial. We evaluated retrospectively the impact of women patients in comparison with men undergoing CABG on mid-term outcome. METHODS: Between December 2014 and March 2022, 1,044 consecutive patients (162 females, 15.5%, 882 males, 84.5%) underwent isolated CABG. The mean follow-up was 40±27 (median 38) months. Logistic and Cox model analysis regressions were used to assess the risk of female gender and other variables, Kaplan-Meier estimates to assess survival rates...

Objectives: Analyses of incidence and time required to heal sternal wound infections after heart surgery performed via a median sternotomy between 2020 and 2022. Results: Superficial wound infections (SWI) were five times more common (2.7%) than mediastinitis (0.5%) among 2693 patients. The median time between the operation and diagnosis of SWI was 26 (interquartile range [IQR] 15-33) days vs. 16 (IQR 9-25) days for mediastinitis ( p  = .12). Gram-negative bacteria caused 44% of the 85 infections...

OBJECTIVES: Left internal mammary artery (LIMA) graft stenoses detected at early coronary angiography may be reversible and consequently prompt unnecessary graft revision. We aim to investigate the frequency, natural course, and clinical significance of internal mammary artery graft stenosis upon early angiography in patients undergoing hybrid myocardial revascularization. METHODS: In this retrospective sub-study of the Coronary Hybrid Revascularization Study, we compared graft appearance, ie, stenosis degree and flow, on early (in-hospital) and scheduled follow-up coronary angiography after 1 year...

Coronary artery bypass grafting (CABG) is and continues to be the preferred revascularization strategy in patients with multivessel disease. Graft selection has been shown to influence the outcomes following CABG. During the last almost 60 years saphenous vein grafts (SVG) together with the internal mammary artery have become the standard of care for patients undergoing CABG surgery. While there is little doubt about the benefits, the patency rates are constantly under debate. Despite its acknowledged limitations in terms of long-term patency due to intimal hyperplasia, the saphenous vein is still the most often used graft...
