Inflammatory Response, Immunosuppression and Arginase Activity after Cardiac Surgery Using Cardiopulmonary Bypass.

Background: Major surgeries suppress patients’ cellular immunity for several days, but the mechanisms underlying this T-cell dysfunction are not well understood. A decreased L-Arginine (L-Arg) level may inhibit T-cell function. Arginase 1 (Arg 1) is induced after traumatic injury, leading to molecular changes in T cells, including decreased expression of cell surface T-cell receptors (TCRs) and a loss in CD3ζ chain expression.

Endoglin and Other Angiogenesis Markers in Recurrent Varicose Veins.

Background: Surgery on varicose veins (crossectomy and stripping) may lead to recurrence, with clinical and socioeconomic repercussions. The etiopathogenesis of varicose veins has yet to be fully understood.

Objective: Study the expression of endoglin and other molecules involved in the neovascularisation process in patients suffering from this disease.

Synchronous colorectal cancer and abdominal aortic aneurysm treated simultaneously. Is a one-stage surgery a feasible treatment?

The finding of synchronous abdominal aortic aneurysm and colorectal cancer is rare. There is no consensus on which is the best surgical approach, so its management remains uncertain. A 64-year-old man was diagnosed with synchronous abdominal aortic aneurysm and rectal cancer.

Early and late results of open surgical and endovascular treatment of infrarenal abdominal aortic aneurysms, selected according to surgical risk.

Background: Open surgical repair (OSR) and endovascular aneurysm repair (EVAR) surgery are alternative treatments for infrarenal abdominal aortic aneurysm (IRAAA).

Objectives: To compare OSR and EVAR for the treatment of IRAAA.

Methods: 119 patients with IRAAA were electively operated by the same surgeon between January 1, 2006 and December 31, 2015, following selection for OSR or EVAR according to surgical risk.

The First Aortic Endoaneurysmorrhaphy: Ricardo Lozano Monzón (1872-1934).

In 1888, Rudolph Matas described and performed a procedure (endoaneurysmorrhaphy) that revolutionized the treatment of aneurysms, which for centuries had been untreatable or simply involved treatment by ligation and other marginal techniques. In 1940, during the annual meeting of the Matas presented the excellent results he had obtained with 98 endoaneurysmorrhaphies, although none of these cases involved an aortic aneurysm. On November 4, 1904, a Spanish surgeon called Ricardo Lozano Monzón was the first person in the world to perform an endoaneurysmorrhaphy on a patient suffering from an abdominal aortic aneurysm.

Transcaval Access to the Abdominal Aorta: indications of Interest to Surgeons and a Comprehensive Literature Review.

We performed a review of the literature (until August 01, 2019) on the occasion of the first transcaval approach for transcatheter aortic valve implantation in our hospital. This review focuses mainly on the indications of this alternative access route to the aorta. It may be useful for vascular surgeons in selected cases, such as the treatment of endoleaks after endovascular aneurysm repair and thoracic endovascular aneurysm repair.

Decision-making and therapeutic options in intact splenic artery aneurysms: single-center experience and literature review.

Background: Splenic artery aneurysms are rare, potentially serious, and usually asymptomatic. Several methods are currently available to treat them, each with their own advantages and drawbacks. Therefore, its therapeutic paradigm has changed.

Disruption in "Nonanastomotic Section" of an Axillofemoral Bypass: A Thorough Critical Review of the Literature.

This work is a thorough nonsystematic critical review (PubMed/MEDLINE 1950-September 2016) of "disruption in nonanastomotic section of an axillofemoral bypass." Fourteen cases were selected (including that provided by the authors of this publication) dating from 1963 to 2016 (53 years). This type of disruption is a very unusual complication in the axillofemoral bypass.

Negative impact of deep venous thrombosis on chronic venous disease.

Introduction: There are several conditions that may cause chronic venous disease (CVD). It is not known whether the aetiology of CVD can predict disease severity and quality of life (QoL). Our objective is that the severity and QoL of patients with CVD secondary to DVT is different from those without prior DVT.

Clinical experience with bemiparin.

Subcutaneous bemiparin has been evaluated for the prevention of venous thromboembolism (VTE) in moderate to high-risk patients undergoing surgery, and for the acute and long-term treatment of established VTE. General and orthopaedic surgery is associated with VTE incidence rates of 15-60% in the absence of thromboprophylaxis and this can be reduced by over 70% with appropriate thromboembolic prophylaxis. Bemiparin was as effective as unfractionated heparin (UFH) in the prevention of VTE, when both were initiated preoperatively, but was associated with significantly fewer bleeding episodes than UFH.

[Surgical treatment of carotid paragangliomas].

The present article reviews the current panorama of the surgical treatment of carotid paragangliomas. The article begins by discussing surgical indications and preoperative aspects (Shamblins classification, the value of genetic study, informed consent, the utility of embolization, etc). Intraoperative aspects (surgical team) and features of the surgical technique (the patients position, incision and exposition, vessel control and identification of nerves, subadventitial or periadventitial tumoral excision, the need for arterial resection and reconstruction, etc.

[Quality of life and venous thromboembolic disease].

Health-related quality of life (HRQoL) refers to patients' perceptions of their diseases or the application of specific treatments in various areas of their lives, especially the effects on physical, emotional and social well-being. The present article reviews current knowledge about HRQoL in venous thromboembolic disease (VTED). First, the importance and utility of the concept of HRQoL is discussed and then the instruments used to measure this concept are described.

Systemic inflammatory response, bacterial translocation and nitric oxide donors.

Abdominal aortic surgery is relatively common and is associated with considerable post-operative morbidity and death. The aortic cross-clamping (supra or infrarenal) necessary for the insertion of a vascular graft, often in circumstances of haemorrhagic shock (e.e.
