The pattern of the superficial arteries of the hand has been studied utilising the Doppler Flowmeter technique. The superficial arteries of the hand formed several diversified patterns that permitted classification into well defined categories. The arcus palmaris superficialis was complete in 84% of the hands and incomplete in 16%. The arteria digitalis palmaris communis primus took origin from the arch in 94% and from the arterial radialis indicis in 6% of the hands. The arteria princeps pollicis and radialis indicis were quite variable in their origin and frequently differed from the normal textbook description. In 52% of the subjects, the arterial patterns in the right and left hand were different with respect to one or more arteries, while they were identical in 48% of the subjects. It would be unwise to base anything more than tentative conclusions on the data so far accumulated, because of the small population used in this project and the absence of similar studies in the literature.

Double Cystic Artery Originating From the Superior Mesenteric Artery and Right Hepatic Artery: A Case Report.
Cureus

Medicine, Griffith University, Gold Coast, AUS.
The cystic artery is a critical anatomical landmark in both laparoscopic and open cholecystectomy. This report presents a unique case involving two rare anatomical variations: double cystic arteries, along with a superficial branch originating from the superior mesenteric artery (SMA) - a previously unreported combination with significant clinical and surgical implications. Unlike earlier studies, this research provides detailed anatomical and embryological insights supported by high-quality imaging and illustrations to guide surgeons in recognizing and managing this novel variation.

College of Medicine, University of Arkansas for Medical Sciences, Little Rock, AR.
Background: Many variations of the reverse flap design elevated on the medial plantar region have emerged since its introduction. Our aim was to review the literature to provide a broader understanding of the various iterations of the reversed blood-flow flap raised on the medial plantar region. Second, we wished to appraise the reverse medialis pedis flap by review of the literature and presentation of a case report.

Background And Aims: When dealing with severely calcified lesions in endovascular therapy (EVT) for lower extremity artery disease (LEAD), navigating through severely calcified chronic total occlusion (CTO) using hard-tip guidewires can be challenging. To address this issue, we employed a novel highly intensive penetration (HIP) technique. This technique involves modifying the tail of a 0.

Pediatric patients with moyamoya disease frequently show rapid progression with a high risk of stroke. Indirect revascularization is widely accepted as a surgical treatment for pediatric moyamoya disease, but it does not augment cerebral blood flow immediately, which leaves patients at risk for stroke peri-operatively. This delay in flow augmentation may make adding direct bypass the better option.
