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.

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.

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.

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.

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.

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.

Management of iatrogenic common femoral artery injuries in pediatric patients using primary vein patch angioplasty.

Background: Invasive therapeutic and diagnostic procedures remain the most frequent causes of pediatric vascular injuries. Ideal management, especially the indication for surgical treatment, remains controversial. This study evaluates the outcome of surgical repair for iatrogenic common femoral artery (CFA) injuries in pediatric patients using primary vein patch angioplasty.

Redo pedal bypass surgery after pedal graft failure: gain or gadget?

Pedal bypass failure is not always associated with limb loss. Management of critical limb ischemia after failure is controversial. The aim of this study is to evaluate the results of redo bypass procedures to foot arteries in the absence of alternative tibial outflow arteries.

Timing of pedal bypass failure and its impact on the need for amputation.

Although the utility of dorsalis pedis (DP) bypass for limb ischemia has been well established, the fate of limbs with a failed bypass to the DP artery remains unclear. Data of all patients undergoing DP bypass grafting within a 12-year period from two university hospitals' vascular registries were retrospectively reviewed. Outcomes of early (<30 days) and delayed graft failure (>30 days) were examined.

Anatomic basis of right renal vein extension for cadaveric kidney transplantation.

Objectives: The right renal vein (RRV) may be difficult to anastomose in right cadaveric kidney transplantation, especially in obese recipients in whom iliac vessels are deep. In this study, gain of length and feasibility in the presence of vascular variations obtained with three common techniques of renal vein augmentation--clamshell (CS), transverse closure of the inferior vena cava (TC), and cava conduit (CC)--were analyzed and compared to the Carrel-patch technique.

Methods: The renal vasculature and the inferior vena cava of 119 cadavers were accurately dissected and measured, and the vascular variations documented.
