Negative pressure wound therapy for extensive soft tissue defects of the lower extremity in a teenager: A case study.

Key Clinical Message: Negative pressure wound therapy (NPWT) aided in the management of complex soft tissue injury in a 14-year-old girl by managing moisture, reducing oedema, and stimulating wound granulation less than 2 months after the accident and prepared the skin for skin grafting, thus successfully saving the limb.

Abstract: This case study describes the use of a tubular bandage encompassing the whole limb to deliver successful NPWT in the treatment and reconstruction of extensive soft tissue damage extending from the right lower extremity to the hip in a 14-year-old female.

Alternative vein bypass in octogenarians with chronic limb-threatening ischaemia.

Background: Octogenarians are regarded as one of the frailest patient groups among the chronic limb-threatening ischaemia population with high perioperative morbidity and mortality rates. As a result, alternative vein bypass surgery in the absence of sufficient great saphenous vein is often not considered as a potential treatment option. The aim of this study was to compare the results of octogenarians undergoing alternative vein bypass surgery due to chronic limb-threatening ischaemia to younger patients.

Long-Term Results of Autologous Bifurcated Carotid Artery Reconstructions.

Background: Carotid bifurcation revascularization using interposition grafts is rare. While internal carotid artery (ICA) revascularization is regarded as mandatory, the external carotid artery (ECA) is severed in most instances. Long-term results of an autologous bifurcated carotid artery reconstruction are discussed.

Vein Bypass Versus Nitinol Stent in Long Femoropopliteal Lesions: 4-Year Results of a Randomized Controlled Trial.

Objectives: The aim of this study was to compare technical success, patency rates and clinical outcomes of vein bypass (VBP) with angioplasty and nitinol stents (NS) in femoropopliteal Trans-Atlantic Intersociety Consensus (TASC) II C and D lesions.

Summary Background Data: Guidelines widely recommend an endovas-cular-first strategy for long femoropopliteal lesions without sufficient data comparing it with vein bypass surgery.

Methods: A single-center prospective, randomized controlled trial (RCT) was performed, after approval of the local ethics committee, with technical success, primary and secondary patency as primary endpoints.

Preoperative anxiety as predictor of perioperative clinical events following carotid surgery: a prospective observational study.

Background: Psychological factors like anxiety and depression are recognised to play a causal role in the development of cardiovascular disease and they may also influence outcome after vascular surgery procedures. The aim of this study was to investigate the association of anxiety and depression with postoperative outcome following elective carotid surgery.

Methods: Single centre prospective observational study of patients treated for asymptomatic carotid artery stenosis at an academic vascular surgery centre.

The Upper-Arm Basilic-Cephalic Loop: A Valueable Alternative for Below-Knee Arterial Reconstruction.

Introduction: Despite advances of endovascular interventions, bypass surgery remains the gold standard for treatment of long and complex arterial occlusions in the lower limb. Autologous vein is regarded superior to other options. As the graft of first choice, the great saphenous vein (GSV) is often not available due to previous bypass, stripping or poor quality.

Alternative Venous Conduits for Below Knee Bypass in the Absence of Ipsilateral Great Saphenous Vein.

Objective: Vein is regarded superior to artificial graft in peripheral arterial bypass surgery. However, this option is often limited owing to previous use or removal of the ipsilateral greater saphenous vein (iGSV). In this case, the contralateral great saphenous vein (cGSV), the small saphenous vein (SSV), or arm veins (AV) are possible alternatives.

Arm Vein versus Small Saphenous Vein for Lower Extremity Bypass in the Absence of Both Great Saphenous Veins.

Background: Bypass surgery remains the gold standard for long and complex arterial occlusions in the lower limb. The vein is regarded superior to prosthetic conduits in peripheral arterial bypass surgery. However, this option is often limited because of previous bypass, stripping, or poor quality of the ipsilateral and/or contralateral great saphenous vein (GSV).

Nitinol Stent Versus Bypass in Long Femoropopliteal Lesions: 2-Year Results of a Randomized Controlled Trial.

Objectives: This study sought to compare patency rates and clinical outcomes of nitinol stents and primary vein bypass in long femoropopliteal lesions.

Background: An endovascular-first strategy for long femoropopliteal lesions is widely recommended without sufficient data comparing it with bypass surgery. Nitinol stents are widely used as the standard endovascular therapy.

Trans-Iliac Bypass Grafting for Vascular Groin Complications.

Objectives: Groin complications following vascular reconstruction, extensive trauma, or severe radiation induced scarring may complicate future revascularisation procedures of the lower limb. Although several techniques have been described, only few cases of trans-iliac bypass grafting have been published. The aim of this study was to perform a review of the literature on trans-ilac bypass grafting and add the authors' experience.

Small Saphenous Vein and Arm Vein as Bypass Grafts for Upper Extremity Ischemia.

Background: Bypass in the upper extremity is a rare procedure mainly performed for chronic ischemia, trauma, or hemodialysis access complications. Feasibility and success of use of the arm vein and small saphenous vein (SSV) for autologous vein bypass have been reported in peripheral artery bypass procedures. There are very few reports on the use of alternative veins in upper extremity bypass.

The Small Saphenous Vein: An Underestimated Source for Autologous Distal Vein Bypass.

Objectives: The small saphenous vein (SSV) is a potential vein source for bypass if neither greater saphenous vein nor arm vein is available. This study reports experience using SSV as part of an all autologous vein bypass policy.

Methods: This study comprised single centre retrospective data analysis of all consecutive patients treated at an academic tertiary referral centre from January 1998 to February 2017 using the SSV as the main peripheral bypass graft.

Alternative Debranching in Patients with Thoracoabdominal Aortic Aneurysm after Open and Endovascular Aortic Aneurysm Repair.

Management of recurrent thoracoabdominal aneurysmal disease of the aorta is challenging. We report three patients with previous endovascular or open aortic repair requiring redo repair by treatment by stent-graft implantation of the thoracoabdominal aorta and visceral debranching using an antegrade inflow from the ascending aorta. All three interventions were successful, with two patients alive 5 and 2 years, respectively, after this operation, while the third patient died 2 days after the procedure due to cardiac failure.

Autologous Bifurcated Carotid Artery Reconstruction: Technique and 2 Year Follow Up.

Objective/background: Carotid bifurcation resection with subsequent reconstruction is performed infrequently. While internal carotid artery (ICA) revascularisation is regarded as mandatory, the external carotid artery (ECA) is severed in most instances. Indications for and results of an autologous bifurcated carotid artery reconstruction are discussed.

Arteriovenous shunts as venous access in children with haemophilia.

Introduction: Venous access is essential in patients with haemophilia for administration of factor concentrates. Peripheral venipuncture may be challenging, particularly in young children or during immune tolerance induction (ITI). Central venous access devices (CVADs) carry a significant risk for complications.

Tibiodistal vein bypass in critical limb ischemia and its role after unsuccessful tibial angioplasty.

Objective: Technical progress in angioplasty expanded its application to very distal arterial lesions of the lower extremity. In cases of unsuccessful angioplasty tibiodistal bypass surgery may be required for limb salvage. We investigated the long-term outcome of this technique in patients with critical limb ischemia.

Paclitaxel-coated versus plain balloon angioplasty in the treatment of infrainguinal vein bypass stenosis.

Objective: The aim of this study was to compare the clinical and hemodynamic outcomes of plain vs paclitaxel-coated percutaneous transluminal angioplasty (PTA) in patients with infrainguinal vein bypass stenosis.

Methods: A single-center retrospective analysis was conducted of consecutive patients treated by infrainguinal bypass PTA. Primary study end points were primary and assisted primary patency.

Arm veins versus contralateral greater saphenous veins for lower extremity bypass reconstruction: preliminary data of a randomized study.

Background: The aim of this randomized study was to determine whether arm vein (AV) or contralateral greater saphenous vein (CGSV) is the better alternative vein source for lower extremity bypass reconstruction.

Methods: Consecutive patients with absent ipsilateral greater saphenous vein undergoing lower extremity revascularization were allocated to group A (AV bypass) or B (CGSV bypass).

Results: From 6, 2010, to 11, 2013, 64 patients (32 each group) were randomized.

Bioabsorbable stent implantation vs. common femoral artery endarterectomy: early results of a randomized trial.

Purpose: To compare clinical and hemodynamic outcome in patients undergoing treatment of common femoral artery (CFA) atherosclerotic lesions by bioabsorbable stent implantation (BASI group) or by common femoral artery endarterectomy (CFE group).

Methods: A randomized, controlled, single-center, open-label trial was initiated to compare outcomes of BASI or CFE in patients with chronic atherosclerotic occlusive lesions in the CFA. From May 2011 to April 2013, 116 consecutive patients were recruited; after excluding 36 patients, 80 patients (52 men; mean age 72.

Characterization of the vasa vasorum in the human great saphenous vein: a scanning electron microscopy and 3D-morphometry study using vascular corrosion casts.

The vasa vasorum (VV) of explanted segments of the human great saphenous vein (Vena saphena magna; HGSV), harvested during dissection for coronary bypass grafts or diseased vein segments from the "Salzburger Landesklinikum," were studied by scanning electron microscopy and three-dimensional morphometry of microvascular corrosion casts. The main objective of this study was to examine the VV's structural arrangement in order to find the most vital segments of the HGSV and in turn to improve the results of coronary bypass surgeries. The study presents a meticulous analysis of the whole microvascular system of the VV of the HGSV and its three-dimensional arrangement.

Successful repair of bilateral common carotid artery dissections from hanging.

The management of blunt carotid artery dissections caused by hanging remains controversial, especially with regard to diagnostic work-up and treatment options. We present 2 men, 49 and 41 years of age, who were treated for bilateral common carotid artery dissection caused by strangulation. In the first patient, additional cricotracheal separation and blunt thyroid gland trauma was observed.

Ultrasonic vein mapping prior to infrainguinal autogenous bypass grafting reduces postoperative infections and readmissions.

Objective: Although duplex vein mapping (DVM) of the great saphenous vein (GSV) is common practice, there is no level I evidence for its application. Our prospective randomized trial studied the effect of preoperative DVM in infrainguinal bypass surgery.

Methods: Consecutive patients undergoing primary bypass grafting were prospectively randomized for DVM of the GSV (group A) or no DMV of the GSV (group B) before surgery.
