“…This was graded as: grade 1, 0-7 s "flush" time, normal; grade 2, 8-14 s, equivocal; grade 3, longer than 15 s, poor or abnormal. In some patients, arterial dominance was noted (Husum and Palm, 1978).…”

Following 333 radial artery cannulations, the frequency of complete occlusion of the vessel on the day after removal of the annula was 30%, decreasing to 24% by the 8th day. Arterial occlusion was assessed using a modified Allen's test and an ultrasonic flow meter. The frequency correlated with the type and size of cannula used, being least (3%) with 20-gauge Teflon cannulae, with the degree of bruising, and with the sex of the patient, being significantly greater in women (37.5%) than in men (27%). Other variables such as insertion technique, low cardiac output, anticoagulation after operation and the duration of cannulation were assessed. Using multivariate analysis of 13 variables, it did not appear possible to predict with any certainty the outcome of arterial cannulation. The frequency of major complications was small and no permanent sequelae were detected.

“…These include an incomplete SPA, radial artery dominance of the SPA and absence or malformation of the ulnar artery. 7,21 Gellman et al 19 have classified palmar arch into two categories, complete or incomplete. Coleman and Anson 14 observed the complete form in 78.5% and incomplete form in 21.5% of 650 hands.…”

Introduction: Forearm arteries are frequently used as workhorse site for cardiac catheterization, bypass grafting and haemodialysis access. There is paucity of data on palmar circulation in live human being and only cadaveric data are available till date. We, therefore, made an attempt to look at the various patterns of sufficient or insufficient palmar arch circulation and various anomalies of forearm arteries, to discuss their clinical implications. Methods and results: We obtained the forearm and hand arteriograms of patients (n ¼ 302) through radial (n ¼ 200) and ulnar routes (n ¼ 102). Modified Allen's test was normal in all of our patients. On the basis of predetermined parameters angiograms were analysed and findings were divided into three groups. These three groups were further classified as type A, type B, type C superficial palmar arch. Conclusion: We concluded that type A superficial palmar arch is most suitable for providing adequate collateral circulation in case of harvesting of forearm vessel, whereas type C superficial palmar arch appears to be highly susceptible for digital ischemia in case of radial or ulnar artery occlusion. Modified Allen's test alone is not justifiable for documenting good collateral circulation and it should be supplemented by other tests to document good collateral circulation before proceeding to any radical procedure.

“…The lateral volar side was determined according to the dominant digital vessels, the ulnar side of the thumb and index finger, and the radial side of the little finger. [ 21 , 22 ] Once the tourniquets were applied, pressure sensors were inserted between the tourniquet and the skin (Fig. 3 A and B).…”

Digital tourniquets are widely used for the management of digital injuries in emergency departments or outpatient clinics. This study is focused on the pressure analysis of digital tourniquets on some points not covered in the existing literature. A total of thirty volunteers were enrolled in this study. Instantaneous surface pressure was measured at the thumbs, index fingers, and little fingers. We investigated the pressure according to the circumference of digits, tourniquet types, and measurement sites (dorsal and mid lateral volar sides) above the digital vessels. Continuous pressure was measured in artificial silicone models to determine the change of pressure over 2 hours. The average pressure measured on the mid lateral volar side of volunteers fingers were 154.3 ± 54.9 mm Hg by T-RingTM and 162.6 ± 61.0 mm Hg by surgical glove. The pressure on the dorsal side were 224.7 ± 57.7 mm Hg by T-RingTM and 228.8 ± 66.0 mm Hg by surgical glove, each significantly higher than the mid lateral volar side. The circumference of digits did not significantly affect the surface pressure. The pressure pattern did not change significantly over 2 hours in both tourniquet types. The surface pressure of the mid lateral volar side was significantly lower than that of the dorsal side. However, there was no significant pressure difference according to the circumference of digits. Time dependent pressure change were not significantly different between 2 tourniquets.
