The Evolution of Custom Subperiosteal Implants for Treatment of Partial or Complete Edentulism in Patients with Severe Alveolar Ridge Atrophy.

Dental implants have always played an important role in dentistry and have been used to replace missing teeth since around 600 AD. They can be classified into three groups: endosteal, subperiosteal, and transosteal. Over time, different materials have been used to manufacture dental implants and these, in turn, can be divided into three groups: metals, ceramics, and polymers.

Method: The study included CT angiographic images from 254 patients (129 women and 125 men).

Variation in the morphology of spinous processes in the cervical spine - An objective and parametric assessment based on CT study.

Background: Typically, cervical vertebrae display bifid spinous processes. Nevertheless, this feature may vary both between subjects and even within the vertebrae of the same individual. Although such variation can be important in archaeological research, anthropological studies and forensic medicine, it has not so far been the subject of any detailed studies.

Arterio-bronchial fistula as a complication of post-traumatic subclavian artery pseudoaneurysm - radiological findings and outcome.

Post-traumatic arterio-bronchial fistula is a rare cause of life-threatening hemorrhage. We present a case of a ten-year-old patient with a post-traumatic subclavian artery pseudoaneurysm complicated by an arterio-bronchial fistula and occlusion of the subclavian artery. The patient was treated with a stent-graft.

Diameters of Arteries Supplying Horseshoe Kidneys and the Level They Branch off Their Parental Vessels: A CT-Angiographic Study.

Background: The most common renal fusion anomaly is horseshoe kidney (HSK), a condition associated with variable arterial blood supply. The aim of this study was to determine whether the height of origin of the renal artery determines its diameter and whether it differs from the mean diameter of the renal arteries of normal kidneys (NK).

Methods: Computer tomography angiography (CTA) studies of 336 patients (88 HSK and 248 NK) were obtained in a search of renal arteries; these were than classified into four groups according to height of its origin: Group I, branching from the aorta superior to the inferior mesenteric artery (IMA); Group II, branching from the aorta below the IMA; Group III, branching from the iliac artery; and Group IV, originating from the internal and external iliac artery.

Circulating microRNAs as biomarkers for myocardial fibrosis in patients with left ventricular non-compaction cardiomyopathy.

Introduction: Despite the fact that cardiovascular magnetic resonance (CMR) with late gadolinium enhancement (LGE) is a proven method for detecting myocardial fibrosis, there is a need for new and reliable serological biomarkers. Circulating miRNAs could be a practical and attractive alternative. The purpose of the study was to assess the miRNAs well established in myocardial fibrosis - miR-21, miR-29a, miR-30d and miR-133a - in the plasma of patients with left ventricular non-compaction (LVNC) that have areas of LGE assessed by CMR.

The recommended protocol aims to improve the imaging procedure and, most importantly, to standardize conducting MRI scans in all MRI departments.

Ischaemia of the medullary cone after stent-graft implantation in a patient with abdominal aortic aneurysm - a case study.

Preoperative visualization of the Adamkiewicz artery - the vessel which is to a great extent responsible for supplying blood to the medullary cone - is an important step which must be taken before initiating restorative procedures in the aorta. We present a case of a 67-year-old patient who underwent an intravascular stent-graft implantation procedure, due to clinical signs of abdominal aortic aneurysm. Routine pre-operative computed tomography examination failed to demonstrate the Adamkiewicz artery.

Morphological and clinical aspects of the occurrence of accessory (multiple) renal arteries.

Renal vascularization variants vastly differ between individuals due to the very complex embryogenesis of the kidneys. Moreover, each variant may have implications for clinical and surgical interventions. The number of operating procedures continues to grow, and includes renal transplants, aneurysmorrhaphy and other vascular reconstructions.

What Each Clinical Anatomist Has to Know about Left Renal Vein Entrapment Syndrome (Nutcracker Syndrome): A Review of the Most Important Findings.

Nutcracker syndrome (NCS) is the most common term for compression of the left renal vein between the superior mesenteric artery and the abdominal aorta. The development of NCS is associated with the formation of the left renal vein (LRV) from the aortic collar during the sixth to eighth week of gestation and abnormal angulation of the superior mesenteric artery from the aorta. Collateralization of venous circulation is the most significant effect of NCS.
