Fibrinolysis in Decidual Spiral Arteries in Late Pregnancy
Thrombosis and Haemostasis, 1978SummaryThe fibrinolytic activity of the intimal cells of decidual spiral arteries and the syncytium of placental villi was studied by electron microscopy in ten normal full-term human pregnancies using a modification of the fibrin slide technique.

Spiral CT of Bronchial Arteries in Chronic Thromboembolism
Journal of Computer Assisted Tomography, 1994Computed tomography study of bronchial artery anatomy and evaluation of dilatation and tortuousity as indicators for pulmonary hypertension and surgical risk in patients with chronic thromboembolism were performed.We retrospectively reviewed contrast-enhanced, thin section spiral CT scans of 39 patients undergoing pulmonary thromboendarterectomy ...

Modified arterial switch operation by spiral reconstruction of the great arteries in transposition
The Annals of Thoracic Surgery, 2000Spiral relationship of the normally related great arteries (SRGA) has never been reconstructed in an arterial switch operation.From March 1998 to April 1999, 9 consecutive cases of transposition of the great arteries (TGA) family (from 2 days to 1.6 years old) underwent arterial switch operations with SRGA at our hospital.

Spiral CT arterial portography of the liver.
Radiology, 1993The enhancement characteristics of the liver, aorta, and hepatic vein were evaluated during computed tomography with arterial portography (CTAP) performed with spiral technique in 10 patients. The attenuation of the liver was nearly constant over the scanning interval (average attenuation, 168 HU +/- 16).

Morphological Changes in Spiral Artery of the Mammalian Ovary with Age
Hormone Research, 2008Morphological changes which take place in ovarian arteries at different ages in human and monkey, were investigated by light microscopy, transmission electron microscopy and scanning electron microscopy. The ovarian arteries in both species were characterized by a spiral configuration throughout their course.

Spiral CT during arterial portography.
RadioGraphics, 1996Spiral computed tomography (CT) performed during arterial portography offers several advantages compared with portographic studies based on conventional CT technique. Because all hepatic images are derived from a volume data set acquired during a single 24-32-second breath hold timed to coincide with the phase of peak hepatic enhancement, motion ...

An In Vitro Model of Trophoblast Invasion of Spiral Arteries
2006Extravillous trophoblasts invade the uterine wall (interstitial invasion) and the spiral arteries (endovascular invasion), replacing the cells of the vessel wall and creating a high-flow, low-resistance vessel. We describe a model to allow the interactions between the invading trophoblast cells and the cells of the spiral artery to be directly examined.

The Uterine Spiral Arteries In Human Pregnancy: Facts and Controversies
Placenta, 2006Uterine spiral arteries play a vital role in supplying nutrients to the placenta and fetus, and for this purpose they are remodelled into highly dilated vessels by the action of invading trophoblast (physiological change). Knowledge of the mechanisms of these changes is relevant for a better understanding of pre-eclampsia and other pregnancy ...

Multislice spiral computed tomography angiography of mesenteric arteries
The Lancet, 2001The introduction of multislice technology has improved and expanded the clinical applications of computed tomography angiography (CTA), and it is now possible to detect subtle vascular abnormalities. We optimised a high resolution CTA protocol to study the anatomy of mesenteric arteries with a multislice spiral CT scanner. We showed that multislice CTA

An experience using spiral vein graft as arterial substitute
The Japanese Journal of Surgery, 1981In two patients wih aneurysmal changes due to arteriosclerosis in the axillary and the subclavian artery respectively, spiral vein grafts were used in a substitute for vascular reconstruction. After resection of the aneurysm, these vein grafts resulted in an excellent adaptation to the recipient vessel.
