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 = 302) through radial (n = 200) and ulnar routes (n = 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.

AbstractThe anatomical variations in the arterial supply of the palm are frequently reported. One such variation reported during routine dissection for undergraduate medical students in our college is the absence of superficial palmar arch and presence of persistent median artery. The arterial supply to the palm is in the form of superficial and deep palmar arches. In the present case the median artery and ulnar artery supplies the palm without forming an arch on the left extremity. Awareness of variations in the vascular pattern of the palm is clinically important in case of angiographic procedures and surgical emergencies.

A superficial artery may be present in the forearm, arising from the axillary, brachial or superficial brachial arteries and crossing over the origin of the flexor muscles of the forearm to reach the palm (Adachi, 1928; Bergman et al. 1988). When this superficial artery continues as the normal ulnar artery accompanying the ulnar nerve at the wrist, it is referred to as the superficial ulnar artery, with an incidence of ∼4%. When the artery passes below or superficial to the flexor retinaculum in the middle of the forearm, sometimes continuing to join the superficial palmar arch, it is called the superficial median artery, with an incidence of ∼1%. We have observed a relatively rare variation involving the presence of a superficial median artery in both upper limbs. We discuss the clinical importance and the developmental aspects of this arterial variation.

Interesting Area

Background: The complex and variable pattern of the arterial arcades of the palm form an interesting area of study anatomically and surgically. In the present study arches were classified into complete and incomplete types, the complete type being the most prominent in 88.6% of the palms. Among the complete type, arch formed by ulnar artery alone supplying the thumb and index finger was found in majority of the specimens (50%). The classical or standard superficial palmar arch formed by the superficial palmar branch of radial and ulnar arteries was found in only 28.5%. Different patterns of the arterial arcades of the superficial palmar arch are normally encountered during routine anatomical dissections of the palm which needs to be emphasized and highlighted for a desired surgical out come during microvascular reconstructive surgeries of the palm and during radial artery cannulation. Context: With technological advancements in microsurgical procedures of the hand, fields of anatomical interest like the classification of arterial arcades of the palm, now becomes essential for operating vascular surgeons for a desired surgical outcome Purpose of the study: The present study was taken up to analyze and document varying patterns of the arterial arcades of the superficial palmar arch. Methods and Material: the study was conducted by dissecting 70 randomly obtained formalin fixed cadaver palms. Results: In the present study arches were classified into complete and incomplete types, the complete type being the most prominent in 88.6% of the palms. Among the complete type, arch formed by ulnar artery alone supplying the thumb and index finger was found in majority of the specimens (50%). The classical or standard superficial palmar arch formed by the superficial palmar branch of radial and ulnar arteries was found in only 28.5%. Out of the 70 hands, incomplete arches were found only in 8 hands with an incidence of 11.4%. Conclusion: Knowledge of arterial pattern of the hand is very important to vascular and reconstructive surgeons for effective treatment of injuries of the hand. Such a knowledge of the disposition of the arterial arcades of the palm also enables cardio-vascular surgeons to plan and modify surgical procedures such as radial artery harvesting, cannulation and in preventing the ischemia of hands in such procedures. KEY WORDS: Superficial palmar arch, Arterial arcades, Complete arch, Incomplete arch.

Allen's Test

Allen's test has been performed quantitatively by measuring digital systolic pressure during compression of the radial or ulnar artery at the wrist. The reduction of pressure in normal subjects was less than 25 per cent. Insufficiency of the arterial supply to the hand from the radial artery, the ulnar artery or the palmar arcades can easily be diagnosed from an abnormal reduction in digital systolic pressure during arterial compression.

Introduction A proximal ulnar artery arteriovenous fistula (PUA-AVF) is a logical vascular access option when the distal ulnar artery is occluded or inadequate in addition to other specific vascular anatomic variants. This study reviews a series of patients where the proximal ulnar artery was used for AVF inflow in establishing a reliable autogenous access for these uncommon patients. Materials and methods All new patients referred for vascular access with a PUA-AVF created during an eight-year period were evaluated. In addition to physical and ultrasound examinations, all patients had an Allen's test performed augmented with Doppler evaluation of the palmer arch. Analysis placed these patients into three anatomic groups: 1) A dominant radial artery with distal ulnar artery occlusive disease; 2) No cephalic or basilic vein option with an isolated and intact brachial vein originating from the ulnar vein for later staged transposition; 3) A proximal radial artery ≤2 mm in diameter and a normal Doppler augmented Allen's test. Results PUA-AVFs were created in 32 new patients during an eight-year period. Primary and cumulative patency rates were 80% and 94% at 12 months and 55% and 81% at 36 months. Follow-up was 2-62 months (mean 14 months). No patients developed steal syndrome during the study period. Conclusions A PUA-AVF is a safe and reliable autogenous access. It is particularly important when the radial artery is the only or dominant arterial supply to the hand, in patients with small but patent radial arteries, and in selected individuals requiring a brachial vein transposition.

Introduction: The superficial palmar arch plays a vital role in the blood supply to the hand. The knowledge of variations in the pattern of superficial palmar arch and its branches, and caliber of these arteries, has become more important for surgeons in reconstructive hand surgeries and radial artery harvesting for myocardial revascularization. The aim of this study was to observe the variations and measure the diameter of contributing arteries of the arches. Materials and methods: In the present study, thirty hands from formalin fixed adult human cadavers were dissected. Normal pattern as well as variations in the arteries contributing to the arch, completeness of arch, and the branching pattern were observed and noted. With the help of a digital caliper, the diameters of ulnar and radial arteries and median artery were taken at the level of the wrist and statistical analysis of the results was done. Results: It was observed that in 96.7 % cases, the superficial palmar arch was complete where there was anastomosis between the arteries forming the arch. In 3.3% cases, the arch was incomplete. The complete arch was divided into radioulnar (36.7%), ulnar (56.7%) and medianoulnar (3.3%) types. The diameter of superficial palmar branch of radial artery was found to be significantly less than the diameter of ulnar artery. (p=0.003). Conclusion: The data obtained on variations and morphometry of superficial palmar arches will certainly be useful in planning and choosing appropriate and safe surgical procedures to prevent inadvertent outcome.

Abstrak: Arteri radialis semakin sering dipergunakan sebagai akses alternatif angiografi koroner dan intervensi karena dibanding akses femoralis, komplikasi perdarahan lebih rendah, mobilisasi lebih dini, dan biaya lebih murah. Terdapat beberapa hal yang dapat mengurangi keberhasilan prosedur ini; salah satunya ialah kegagalan pungsi karena ukuran a. radialis yang kecil. Studi sebelumnya menunjukkan bahwa uji Allen dapat digunakan untuk mendeteksi arteri dengan diameter yang lebih besar. Penelitian ini bertujuan untuk mengevaluasi apakah uji Allen dan inverse Allen berkorelasi dengan diameter a. ulnaris dan a. radialis. Penelitian ini berlangsung dari Juli hingga Desember 2012 di Laboratorium Kateterisasi Rumah Sakit Awal Bros Makassar. Pasien menjalani uji Allen dan inverse Allen sebelum prosedur. Ukuran diameter dalam dari lumen arteri radialis dan ulnaris diukur oleh operator dengan menggunakan analisis angiografi kuantitatif (operator tidak mengetahui hasil uji Allen). Uji Spearman’s rho digunakan untuk menganalisis korelasi antara uji Allen dan inverse Allen dengan diameter a. radialis dan a. ulnaris dengan P < 0,05 dianggap bermakna. Analisis statistik menggunakan SPSS versi 19. Hasil penelitian memperlihatkan 121 pasien (98 laki-laki dan 23 perempuan, rerata usia 57,5 (SD ± 11,9 tahun). Frekuensi crossover 3,3%. Uji Allen dan inverse Allen normal pada 116 pasien (95,8%). Rerata diameter a. radialis dan ulnaris ialah 2,14 (SD ± 0,34 mm) dan 1,95 (SD ± 0,45 mm). Uji korelasi Spearman’s rho menunjukkan korelasi bermakna antara uji Allen dan diameter a. ulnaris (P = 0,000; r = -0,485); uji inverse Allen dan diameter a. radialis (P = 0,015; r = -0,220). Simpulan: Terdapat korelasi bermakna antara uji Allen  dengan diameter a. ulnaris, dan uji inverse Allen dengan diameter a. radialis. Kedua uji ini sederhana dan dapat memberikan informasi tentang arteri mana memiliki diameter yang lebih besar. Bila uji Allen normal, maka a.ulnaris dapat dipergunakan sebagai akses alternatif ketika akses radialis gagal atau bahkan sebagai akses inisial jika uji inverse Allen abnormal atau waktu uji Allen lebih singkat dari inverse Allen, terutama untuk prosedur intervensi yang memerlukan arteri yang lebih besar sebagai akses. Kata kunci: uji Allen, uji inverse Allen, diameter, arteri radial, arteri ulnaris.   Abstract: Radial artery has been increasingly used as an alternative site for coronary angiography and intervention because of its advantages over femoral access, such as: a reduction in bleeding complications, early mobilisation, and lower cost. Despite these advantages, there are some challenges that reduce procedural success. One of them is the puncture failure owing to the small vessel size. A previous study has demonstrated consistently that the Allen test may be used for detecting the artery with the largest diameter. This study aimed to evaluate whether the Allen’s and inverse Allen’s tests correlate to the diameters of ulnar and radial arteries. This study was conducted from July to December 2012 in the Catheterization Laboratory of Awal Bros Hospital Makassar. Patients underwent the Allen’s and inverse Allen’s test before the procedure. The inner luminal diameters of radial and ulnar arteries were measured by an operator using quantitative angiographic analysis software. The operator was blinded to the results of the Allen’s tests. The Pearson correlation test was used to analyze the correlation between Allen’s and inverse Allen’s test with the diameters of the radial and ulnar arteries. A P-value of < 0.05 was considered as statistically significant. Statistical analysis was performed with Statistical Package for Social Sciences (SPSS) version 19. The results showed that there were 121 patients (98 males and 23 females, the mean age being 57.5 (SD ± 11.9 years). The crossover rate was 3.3%. Both of the Allen’s and inverse Allen’s tests were normal in 116 patients (95.8%). By using a quantitative coronary analysis software, the mean diameters of the radial and the ulnar arteries were  2.14 (SD ± 0.34 mm) and 1.95 (SD ± 0.45 mm), respectively. The Spearman’s rho correlation test showed significant correlations between the Allen’s test and diameters of ulnar arteries (P = 0.000; r = -0.485), and between the inverse Allen’s test and diameters of radial arteries (P = 0.015; r = -0.220). Conclusion: The Allen’s test correlated to the diameters of the ulnar arteries and the inverse Allen’s test correlated to the diameters of the radial arteries. The normal Allen’s test indicated that the ulnar artery might be used as an alternative access site when the radial approach failed or even as an initial access if the inverse Allen’s test was abnormal or the Allen’s test was shorter than the inverse Allen’s test, especially for the intervention procedure which needed a larger artery as the access site. These tests are simple and may provide some important information about arteries with larger diameters. Future studies with larger series of patients will be necessary to confirm our results. Keywords: Allen’s test, inverse Allen’s test, diameter, radial artery, ulnar artery.

Backgorund / Aim. In-depth knowledge of the vascular network of hand is of great importance in modern medicine. The main vessel of hand is the superficial palmar arch. As typically described in anatomical textbooks, it arises as terminal branch of the ulnar artery which then anastomoses with the superficial palmar branch of the radial artery. However, the superficial palmar arch is characterized by remarkable variability, which was the area of interest of many researchers so far. Comprehensive examination of the anatomy of the superficial palmar arch which included two parameters - the formation of the superficial palmar arch and its localization in relation to the topographic landmarks of the hand. Methods. Research was conducted on a total number of 14 cadavers. After careful dissection, variations and distance of the superficial palmar arch from Kaplan?s cardinal line were observed on the right hands. Collected data were then analyzed statistically in SPSS 11.0 using the Mann-Whitney U test, with the accepted level of statistical significance of p < 0.05. Results. According to Coleman and Anson classification, the higher incidence of incomplete type (57.14%) of the superficial palmar arch should be in comparison to complete type (42.86%). In addition to this, a statistically significant difference discovered in distance of the superficial palmar arch from Kaplan?s cardinal line between two groups with complete and incomplete types, respectively. The parameter examined in the group with complete type took the value of 2.13 ? 0.32 cm, while in the group with incomplete type measured 3.33 ? 0.87 cm. Conclusion. The present study showed a very important complexity in the domain of anatomy of the superficial palmar arch with numerous clinical implications. For that reason, a thorough evaluation of the hand circulatory system should be considered while planning surgical procedures in order to avoid operative and postoperative complications.

Introduction: The superficial palmar arch (SPA) is the main source of arterial supply to the palm. It is an arterial arcade formed mainly by the ulnar artery and is completed by the superficial palmar branch of the radial artery. The study was conducted with objective to study the variations in formation of superficial palmar arch in Nepalese cadaveric hands. Methodology: Two horizontal incisions were made, one at the wrist joint and another incision along the root of fingers. A vertical incision was made from the middle of the wrist to the 3rd metacarpo-phalangeal joint. The skin of the palm and the palmar aponeurosis was reflected. The surrounding adipose tissue was removed to view the superficial palmar arch and its branches. Result: In present study, out of 50 specimens of hands, 64% of superficial palmar arch was formed as normal pattern and in 36% cases it was formed by ulnar artery alone. Normal SPA pattern was seen 63% in male and 66.7% in female i.e. higher percentage in female than in male but it was statistically insignificant (P<0.05). SPA-ulnar artery alone pattern was seen 37% in male and 33.3% in female i.e. higher percentage in male than in female, however it was also statistically insignificant (P<0.05). Conclusion: Normal pattern of SPA observed in Sixty-four percent of Nepalese hands and in thirty-six percent cases it was formed by ulnar artery alone. There was no statistically significant difference in SPA pattern distribution between Nepalese male and female.
