Oxidative DNA Damage and Arterial Hypertension in Light of Current ESC Guidelines.

A new insight into oxidative stress is based on oxidative deoxyribonucleic acid (DNA) damage. DNA is the pivotal biopolymer for life and health. Arterial hypertension (HT) is a globally common disease and a major risk factor for numerous cardiovascular (CV) conditions and non-cardiac complications, making it a significant health and socio-economic problem.

Surgical treatment of thoracoabdominal aortic pathology - retrospective study of 300 patients.

Introduction: Thoracoabdominal aortic surgery is a technically demanding and extensive treatment that has its place in the era of endovascular techniques. To ensure the best possible outcomes, it requires a well-coordinated team of surgeons, anaesthetists, intensive care physicians and other medical staff.

Methods: The authors present a series of 300 patients operated on between 1 January 2003 and 15 March 2022.

Mendelian Susceptibility to Mycobacterial Disease: The First Case of a Diagnosed Adult Patient in the Czech Republic.

We present a case of a 42-year-old woman with Mendelian susceptibility to mycobacterial disease. The disease was diagnosed at an adult age with relatively typical clinical manifestations; the skeleton, joints, and soft tissues were affected by nontuberculous mycobacteria: , , and . A previously published loss-of-function and functionally validated variant NM_000416.

Abdominal aortic aneurysm as an IgG4-related disease.

The objectives of this study were to evaluate patients with aortic abdominal aneurysm (AAA) with regard to immunoglobulin (Ig)G4-related disease (IgG4-RD). IgG4-RD represents a recently defined condition comprised of a collection of disorders characterized by IgG4 hypergammaglobulinemia, the presence of IgG4-positive plasma cells in organs affected with fibrotic or sclerotizing changes and typical histopathological features. It was identified as a possible cause of vasculitis in large vessels.

Isolated Arteritis of Both Lower Limbs.

Isolated arteritis of the lower limb vessels is an extremely rare condition. The use of modern vascular imaging techniques substantially facilitates and accelerates the diagnostics. In the isolated lower limb arteritis, it is always necessary to exclude Takayasu's and giant-cell arteritis.

[Changes in the true and false visceral segment lumen sizes following endovascular treatment of type B aortic dissections].

Introduction: The aim of the study was to assess technical success rates of endovascular procedures in acute and chronic type B aortic dissections and changes in the right (PL) and false (FL) lumen diameters in the visceral segment region during short-term and long-term follow up study periods.

Methods: From 2004 to 2009, the authors performed a prospective study, which included a total of 33 patients with acute and subacute (n = 16; 48.5%) or chronic (n = 17; 51.

[Current trends in the surgical management of thoracoabdominal aortic aneurysms].

Introduction: The authors present a group of patients, who underwent standard procedures on thoracic (TAA) and thoracoabdominal (TAAA) aortic aneurysms from 01-01-2009 to 15-09-2010.

Material And Methods: During the above time period, a total of 29 patients were operated. The authors employed as many known organ protection procedures as possible, including reduced heparinization, mild hypothermia (32-34 degrees C), sequential aortic clamping cerebrospinal drainage, left heart bypass (a biopump) with non-ischemic canylation of the femoral artery, selective visceral blood perfusion (superior mesenteric artery and coeliac trunk) and renal arteries perfusion using cold crystallic solution.

[Radical operation of infected aortofemoral prosthesis using fresh arterial allograft: our mid-term experience].

Introduction: The mid-term experience with the use of the fresh arterial allografts in the treatment of aortic or aortofemoral prosthetic infection is presented.

Material And Methods: Between 2001-2010 24 patients (23 with the infected graft in aortic or aortofemoral position and one with a mycotic aneurysm of the aortic bifurcation) were operated with the use of the fresh arterial allograft. Male/female ratio was 15/9, average age 65.

[Postoperative re-stenosis of the carotid--A case for reoperation or endovascular management?].

The aim of this work was to assess frequency rates of re-stenoses following surgical or endovasular treatment of re-stenoses after primary endarterectomies of the carotid artery, taking into consideration concomitant disorders and the contralateral findings. Another objective was to assess differences in peroperative and postoperative complications frequency rates. The retrospective study included patients undergoing vascular surgery during a seven-year period.

[Bacterial aortitis].

A cohort of 14 patients with bacterial destruction of various segments of the aortic wall is presented. The Salmonella enteritidis strain was predominantly responsible. Most patients had typical history of symptomatic trias of sepsis, abdominal and/or back pain and positive blood cultures.

[Surgical procedures on the external carotid artery].

A clinical series of five patients operated on for symptomatic cerebral blood flow deterioration is discussed. They presented with either hemispheral symptoms (hemiparesis, amaurosis fugax) or signs of diffuse cerebral hypoxia. In the presence of unilateral or bilateral internal carotid artery (ICA) occlusion a critical stenosis of the external carotid artery (ECA) was confirmed either by duplex ultrasound or angiography.

Ruptured abdominal aortic aneurysm: role of initial delay on survival.

In the years 1990 to 1997, 103 patients with RAAA were operated on at the Department of Vascular Surgery of the Hospital Na Homolce in Prague. Men outnumbered women, mean age was 70 years. The mean delay between onset of symptoms and hospital admission was 25 hours.

[A comprehensive approach to the treatment of popliteal artery aneurysms--personal experience].

Unlabelled: During a five-year retrospective follow-up period the authors treated a group of 46 patients with the diagnosis of aneurysm of the popliteal artery (AAP). The group comprised 42 men (91%) and 4 women (9%). The mean age was 62 years.

[Ruptured abdominal aortic aneurysm].

In the years 1990-1994, 43 patients with ruptured abdominal aortic aneurysms (RAAA) were operated on at the Department of Vascular Surgery of the Na Homolce Hospital in Prague. Men outnumbered women, average patient age was 70 years. The mean delay between onset of symptoms and hospital admission counted 27 hrs.

Analysis of graft healing in a new elastomer-coated vascular prosthesis.

The need for a vascular prosthesis that does not require preclotting is apparent. The use of biological biodegradable coatings may carry the potential disadvantages of undesirable healing, inflammatory or antigenic reactions, and increased thrombogenicity. A graft has been developed to minimize porosity by coating only the outer surface with a bioinert non-absorbable elastomer (mainly Silastic) so as to leave the inner surface unchanged.

[Peroperative transluminal angioplasty as a supplementary procedure to arterial reconstruction surgery].

Patients with affections of the vascular system of the lower extremities at several levels present a complicated problem for vascular surgery. The authors submit their experience with a combination of vascular reconstruction and peroperative transluminal angioplasty. In 25 patients, mean age 64 years, they performed 29 of these combined operations, 10 times on account of claudications, 11 times on account of pain at rest, 8 times on account of trophic defects.

Longitudinal study of cerebral spinal fluid drainage in polyethylene glycol-conjugated superoxide dismutase in paraplegia associated with thoracic aortic cross-clamping.

It has been hoped that pharmacologic prophylaxis in thoracic aortic cross-clamping may avert the unpredictable complication of spinal cord paraplegia, may avoid the mechanical difficulties associated with shunts, partial bypass, or monitoring devices, and may serve as a substitute for or as an adjunct to cerebral spinal fluid drainage. Toward this end 21 mongrel dogs were studied in four groups and underwent 60 minutes of thoracic aortic cross-clamping: group I, five with thoracic aortic cross-clamping; group II, five with thoracic aortic cross-clamping and cerebral spinal fluid drainage; group III, five with thoracic aortic cross-clamping, cerebrospinal fluid drainage and intravenous administration of a single dose (5000 units/kg) of polyethylene glycol-conjugated superoxide dismutase (PEG-SOD) given 15 to 20 minutes before thoracic aortic cross-clamping; and group IV, six with thoracic aortic cross-clamping and PEG-SOD. Paraplegia was graded by the Tarlov method at 24 hours and up to 5 days after thoracic aortic cross-clamping.
