A tortuous artery is one that twists and winds in a “tortuous” path.
An Update on Radial Artery Access and Best Practices for Transradial Coronary Angiography and Intervention in Acute Coronary Syndrome: A Scientific Statement From the American Heart Association. The incredible ibex defies gravity and climbs a dam | Forces of Nature with Brian Cox - BBC - Duration: 3:53.
In addition to the higher incidence of loops in the right radial artery, the right subclavian artery is often more tortuous than the left, especially in patients with short stature and those who are elderly. Left hand radial access (hand is mildly flexed to achieve comfortable operation). The overall incidence of radial artery anomaly was 12.6% (n = 82).
7 Additionally, in the right radial route, the catheter has to pass not only through the right subclavian artery, but also the brachiocephalic trunk before reaching the aortic root.
40 (6.2%) patients had a high-bifurcating radial origin, 8 (1.2%) had a full radial loop, 14 (2.1%) had extreme radial artery tortuosity and 20 (3%) had other anomalies such as persistent left subclavian artery and extreme subclavian tortuosity. J Invasive Cardiol. Arterial tortuosity syndrome (ATS) is an extremely rare genetic disorder characterized by lengthening (elongation) and twisting or distortion (tortuosity) of arteries throughout the body. Connective tissue provides strength and flexibility to structures throughout the body, including blood vessels, skin, joints, and the gastrointestinal tract. 70 The ideal ratio of inner diameter of radial artery to sheath outer diameter has been found to be 0.9. Arterial tortuosity syndrome is a disorder that affects connective tissue.

Stricture of artery.
Serial roadmaps showing the navigation through the A, radial and B, subclavian arteries.C and D, Target fusiform 9.2 mm aneurysm, involving the left vertebral artery, incorporating the takeoff of the ipsilateral PICA artery.C and D, Unsubtracted image after deployment of a single PED across the aneurysmal neck. A Tortuous Path: Radial Artery Catheterization An image can be worth a thousand words. 2011 Jun;23(6):E153‐5. 3 As its name suggests, arterial tortuosity syndrome is characterized by blood vessel abnormalities, particularly abnormal twists and turns (tortuosity) of the blood vessels that carry blood from the heart to the rest of the body ( the arteries ). Tortuous Brachiocephalic Artery • During TRI, we sometimes encounter the cases in which crossing a catheter are difficult due to severely tortuosity of the brachiocephalic artery. 8-2). BBC Recommended for you Radial artery perforation is more likely to occur in patients with small radial arteries, in the elderly with tortuous radial arteries, in hypertensive patients, in radial artery loops and, more importantly, in cases of inadvertent forceful manipulation of the guidewire and catheter. The radial vessel can sometimes be very tortuous and even have loops (In about 10 percent or less of patients), which can make navigating the arm difficult. Shroff said he uses a 0.035-inch wire without fluoroscopy, which usually passes into the aorta easily 90 percent of the time.
The brachial artery can be accessed if the radial artery has recently been punctured or is otherwise not available (Fig. Tortuous arteries are usually only noted when they begin to cause problems, and they pose many health risks. If there is difficulty advancing a catheter through a tortuous or spasmed radial artery, balloon-assisted tracking (BAT) might solve the problem. 2018 Sep;11(9):e000035. Traversing these two areas of …
It carries a greater risk of complication, including trauma to the basilic vein or median nerve. Radial artery diameter may potentially limit the maximum size of radial artery introducer sheath, especially as the external diameter of the introducing sheath is 2 Fr larger than its internal diameter. The X-rays may show abnormalities in an artery that help confirm SCAD.A coronary angiogram can also show if the arteries in the heart (coronary arteries) are abnormal and twisted (tortuous arteries). Arteries are the blood vessels that carry oxygen-rich blood away from the heart. Ulnar artery is the largest terminal branch of brachial artery given off in the cubital fossa. In spontaneous coronary artery dissection (SCAD), the arteries in the heart (coronary arteries) may sometimes be twisted (tortuous arteries). Matsukage T, et al. Heart with tortuous coronary arteries.
Circ Cardiovasc Interv. Tortuous arteries may be genetic or caused by other health conditions, such as thickening of the arteries or simple aging. On its further course, it lies beneath the superficial flexor muscles of forearm in the proximal third of forearm and in the distal two third of forearm it descends vertically downwards with the sub fascial course [1].
