Macrovascular blood supply to the ventrolateral aspect of the rat’s abdominal wall. A, Schematic representation of the angiosomes of the ventrolateral aspect of the rat. The angiosomes of the abdomen studied in the present study are represented are numbered in Arabic numerals and represented in different colors. The adjacent angiosomes are numbered in roman numerals and highlighted in different levels of gray. These angiosomes have been represented according to Taylor et al.32,33 and Kochi et al.40 B, Photograph of the integument covering the ventrolateral aspect of the abdomen of the rat after processing by the modified Spalteholz technique showing the supplying vessels and respective angiosomes. The top limit of the photograph corresponds to the lower limit of the rib cage, the lower limit to a transverse line abutting the pubic symphysis; the lateral limits of the photograph correspond to the dorsal axillary lines. C and D, Representative infrared thermography images of the ventrolateral aspect of the abdomen of the rat. C, Direct infrared thermography with hotspots in the region of the dominant axial vessels (the caudal superficial epigastric vessels). D, Infrared thermography after cooling of the rat’s surface, by placing a silicone gel bag at a temperature of approximately 21°C for 2 minutes. This image shows the location of the dominant perforator vessels in the central and cranial aspect of the abdomen. The thermograms were taken for a period of 5 minutes with 30-second intervals. Ca, caudal; Cr, cranial; Le, left; La, lateral; M, medial. I, median angiosome; II, ulnar angiosome; III, deep brachial angiosome; IV, transverse cervical angiosome; V, dorsal circumflex humeral angiosome; VI, circumflex scapular angiosome; VII, internal thoracic angiosome; VIII, cranial intercostal perforators angiosome; IX, lateral circumflex femoral angiosome; X, medial circumflex femoral angiosome; XI, superficial external pudendal angiosome; XII, caudal gluteal angiosome; XIII, internal pudendal angiosome; XIV, saphenous angiosome; XV, fibular angiosome; XVI, anterior tibial angiosome. 1, thoracodorsal angiosome; 2, LT angiosome; 3, cranial epigastric angiosome; 4, caudal intercostal perforators angiosome; 5, superficial caudal epigastric angiosome; 6, lumbar (or iliolumbar) perforators angiosome; 7, deep circumflex iliac angiosome; 8, deep external pudendal angiosome; 9, superficial external pudendal angiosome; 10, deep caudal epigastric angiosome; 11, cranial deep epigastric artery perforator; 12, LT artery; 13, thoracodorsal artery perforator; 14, intercostal perforators; 15, perforators from the medial branch of the deep caudal and cranial epigastric arteries; 16, perforators from the lateral branch of the deep caudal and cranial epigastric arteries; 17, choke vessels between the two superficial caudal epigastric angiosomes; 18, anastomoses between the superficial caudal epigastric arteries and the LT arteries; 19, medial branch of the SIEA; 20, lateral branch of the SIEA; 21, lumbar perforators; 22, SIEA; 23, superficial EPA; 24, deep EPA; 25, deep circumflex iliac artery.
