Only a small subset of patients with combined superficial femoral artery and vein injuries results in amputation. The importance of the venous component as a risk factor for amputation is uncertain. Ligation vs. reconstruction of venous injuries is controversial. For clarification of these issues, we analyzed retrospectively multiple risk factors for amputation in combined superficial femoral artery and vein injuries in a civilian population. There were 25 patients treated in a 20-year period. Sixteen injuries were caused by small caliber missiles, six by shotgun blasts, and three by knife wounds. Three patients (12%) ultimately underwent amputation. The major risk factor for amputation was method of vascular reconstruction. All three amputations underwent ligation of the superficial femoral vein with arterial reconstruction by placement of a reversed interposition saphenous vein graft (p = 0.0009). None of the remaining 22 patients with salvaged limbs underwent reconstruction by this combination of techniques. Consequently, the authors emphasize the importance of venous reconstruction, particularly in combined injuries with major arterial involvement requiring interposed grafts.

Background And Aims: When dealing with severely calcified lesions in endovascular therapy (EVT) for lower extremity artery disease (LEAD), navigating through severely calcified chronic total occlusion (CTO) using hard-tip guidewires can be challenging. To address this issue, we employed a novel highly intensive penetration (HIP) technique. This technique involves modifying the tail of a 0.

Background: Hydrogen sulfide (HS) is a widely studied gasotransmitter, and its protective effect against ischemia-reperfusion damage has been explored in several studies. Therefore, a requirement exists for a comprehensive study about HS effects on ischemia-reperfusion damage in flap surgery. The aim of this study is to examine the effect of hydrogen sulfide by creating ischemia-reperfusion injury in the vascular-stemmed island flap prepared from the rat groin area.

The interrelationship of thyroid volume and function with features of cardiovascular dysfunction has already been investigated but some aspects remain unclear, especially in terms of subclinical cardiovascular dysfunction in euthyroid patients. Intima-media thickness (IMT) measurement in ultrasound B-mode imaging in different vascular beds (most frequently within the common carotid artery) is one of the most important tools for the detection of subclinical atherosclerosis in both clinical practice and research. This article aimed to present the results of our research on the association between the thyroid evaluation parameters and the IMT measured in both the carotid and femoral arteries in euthyroid patients aged 18 to 65 years taking into account the influence of diabetes, hypertension, and excess body mass.

The anatomy of the sciatic nerve allows it to be blocked at different levels using various anesthetic approaches. However, for several reasons, performing these approaches may be challenging or disadvantageous in specific categories of patients, particularly in obese patients. The objective of this brief technical report is to describe a new technical approach to sciatic nerve block, designed to simplify the procedure for certain categories of patients and less experienced practitioners.

Objectives: Prediction of in-stent restenosis (ISR) is clinically important for patients with peripheral artery disease in their superficial femoral arteries (SFA) who have been treated with stenting. The aim of this study was to construct and validate a predictive model for ISR after SFA stenting based on a series of clinical and ultrasonic parameters.
Methods: This retrospective study included 381 patients who were treated with self-expanding bare nitinol stents in their SFA at our hospital between January 1, 2018, and January 1, 2022.
