In contrast, the details of the “trick” performed within the lower limb to provide blood supply to the posterior leg structures are very different from those seen in the “trick” displayed within the upper limb to provide blood supply to the posterior forearm muscles. In the upper limb, an anterior artery—the ulnar artery that branches from the brachial artery—gives rise to the common interosseous artery, which then divides into the anterior interosseous artery and the posterior interosseous artery, the latter of which provides blood supply to the posterior forearm. In the lower limb, the femoral artery runs through the adductor canal to reach and pass through the adductor hiatus—an opening in the tendon of the adductor magnus muscle just above the knee (Plate 5.6a)—to appear in the posterior side of the knee region. It changes name to popliteal artery as it enters the popliteal fossa (Plate 5.6c). As an aside, note that the saphenous nerve and the nerve to the vastus medialis accompany the femoral artery and femoral vein in the adductor canal, but as noted in Section 5.2.1, the saphenous nerve does not go all the way to the posterior side of the knee region as the popliteal artery and popliteal vein do. Instead, the saphenous nerve remains mainly an anterior nerve also in the leg region, to provide cutaneous innervation to the medial side of the leg (Plate 5.1).
The Triple Heater (TH)

Anterior interosseous artery: Both the anterior and posterior interosseous arteries arise from the common interosseous artery, which branches off of the ulnar artery. Both interosseous arteries course along the interosseous membrane. The anterior interosseous artery supplies both sides of the interosseous membrane by providing a dorsal branch that courses along the distal posterior portion of the interosseous membrane.

The anterior interosseous artery passes distally upon the interosseous membrane, between two of the muscles of the deep layer, the flexor digitorum profundus and the flexor pollicis longus. Distally, the anterior interosseous artery courses deep to the pronator quadratus. Perforating branches of the anterior interosseous artery pierce the interosseous membrane to enter, and assist in the supply of, the extensor compartment, anastomosing with branches of the posterior interosseous artery.

In large soft tissue defects, the primary focus is to minimize donor site morbidity and at the same time, to obtain sufficient flap coverage to preserve limb function. In our case, we chose a PIA flap as a therapeutic option for reconstruction. It was first described as a reverse-flow pedicle flap in 1986 [27–30] and provides a reliable flap with adequate vasculature. to cover wrist and hand defects [31]. The PIA flap does not sacrifice the major blood vessels of the hand because it relies on the posterior interosseous artery and its anastomosis with the anterior interosseous artery, which offers a much-needed alternative option, when the radial or ulnar artery is damaged or when palmar arches are absent. Jones et al. reported that the reverse radial forearm and contralateral free radial forearm flaps are more reliable than the posterior interosseous flap for the coverage of moderate-sized defects of dorsal or palmar hand and wrist defects following trauma or tumor resection [32]. Ultimately, the choice of flap depends on the surgeon’s experience and preference for a particular technique.

RAO is the most serious complication of TRA. Because RAO is generally asymptomatic and the evaluation technique and timing of RAO after procedure is very different in the literature, its incidence varies widely, ranging from 1.5% to even 30.5%, with an average of 10% [13] Just after procedure, RAO rates are higher and subsequently decline with time thanks to spontaneous recanalization that incident rates of 7.7% for early RAO within 24 h decrease to 5.5% at 1 month [14,15]. In addition, only based on the absence of radial artery pulse can lead to underdiagnosis of RAO [14]. Because a palpable pulse alone does not mean the absence of RAO. Rich collateral network by means of mainly the anterior interosseous artery may supply the distal segment of the radial artery occlusion which results in a false impression of radial artery patency. Therefore, using Doppler ultrasound allows more objective information regarding RAO by assessing the structural imaging of the arteries and blood flow with colour Doppler [15,16]. In our study, Doppler ultrasound was used for diagnosis of RAO and RAO was seen in 36 (5.2%) patients at 10th day after cardiac catheterisation. This ratio was consistent with previously reported data in literature [16,17].
