In three separate centers of vascular surgery in Norway, a total of 26 patients underwent implantation of a new bovine arterial graft (Solcograft-P) for femoropopliteal or femorotibial bypass or arterial patch-plasty. Serious complications--graft deterioration and formation of aneurysm or pseudoaneurysm--arose in eight patients, all within 4 months after the implantation. In central Europe only four anastomotic pseudoaneurysms have been reported after about 700 Solcograft implantations, even with longer observation time. Possible causes of the difference in complication rates are discussed.

Objective: Berry syndrome is a group of rare congenital cardiac malformations including aortopulmonary window (APW), aortic origin of the right pulmonary artery (AORPA), interruption of the aortic arch (IAA), patent ductus arteriosus (PDA) (supplying the descending aorta) and intact ventricular septum. This paper will analyze the clinical data of 7 patients with Berry syndrome who underwent surgical treatment in our institution and discuss the one-stage surgical correction of Berry syndrome in combination with the literature.
Methods: From January 2013 to July 2024, a total of 7 children with Berry syndrome were admitted to the Cardiac Surgery Department of Beijing Children's Hospital.
Hybrid Endovascular and Direct Surgical Approach for Treatment of Penetrating Common Carotid Artery Injury: A Case Report.

Although rare, penetrating cervical vascular injury poses significant challenges with a poor patient prognosis, often attributed to severe hemorrhage and accompanying injuries. We encountered a case of hemorrhagic shock resulting from a penetrating injury to the common carotid artery (CCA), which was successfully managed using a combination of endovascular therapy and direct surgical intervention. A 23-year-old man presented with a self-inflicted stab wound on the left side of his neck from a kitchen knife.

Malnutritional stress during gestation is a well-established driver of metabolic disfunction in offspring. Extended exposure to malnutrition requires metabolic plasticity as the animal shifts toward a catabolic state. In this paper we demonstrate the influence of malnutrition throughout gestation on uterine artery hemodynamics and the metabolism of the dam and neonate.

The carotid web is a rare fibromuscular dysplasia disease of the internal carotid artery wall. It is a cause of thromboembolic stroke in a demographic of patients generally younger than those with atherosclerotic carotid artery disease. It is easy to miss the diagnosis without a high index of suspicion.

Gravity may exert species-specific effects on quadrupedal vasoreactivity, reflecting variations in the vertical displacement of the cardiocranial axis from the dorsal plane. Deer show markedly displaced cardiocranial axes compared to their closest phylogenetic relatives, but their relative cerebrovascular responses remain unelucidated. Accordingly, we investigated the responses to noradrenaline (NA), acetylcholine (ACh), 5-hydroxytryptamine (5-HT), histamine, angiotensin (Ang) II, and bradykinin (BK) in cervine basilar arterial rings.
