The lifetime risk for diabetic patients to develop a diabetic foot ulcer (DFU) is 25%. In these patients, the risk of amputation is increased and the outcome deteriorates. More than 50% of non-traumatic lower-extremity amputations are related to DFU infections and 85% of all lower-extremity amputations in patients with diabetes are preceded by an ulcer; up to 70% of diabetic patients with a DFU-related amputation die within five years of their amputation. Optimal management of patients with DFUs must include clinical awareness, adequate blood glucose control, periodic foot inspection, custom therapeutic footwear, off-loading in high-risk patients, local wound care, diagnosis and control of osteomyelitis and ischaemia.

Purpose: To evaluate the clinical outcome of subintimal angioplasty in diabetic patients with critical limb ischemia (CLI) compared to nondiabetics irrespective of the patency status of the treated arteries. Methods: The records of 99 consecutive patients (53 men; median age 78.5 years, range 42–92) suffering from CLI who underwent primary infrainguinal subintimal angioplasty in 112 limbs within a 6-month period were studied retrospectively. A third of the patients (n=33) were diabetic. The technical success, perioperative morbidity/mortality, and clinical success were compared between the diabetic and nondiabetic patients. Kaplan-Meier life-table analysis was used to analyze clinical success, limb salvage, and survival for both groups. Results: The overall technical success was 89% (81% in diabetics, 93% in nondiabetics, p=0.05). Perioperative morbidity was 8% (16.7% in diabetics, 3.9% in nondiabetics, p=0.03). The perioperative mortality was zero. The clinical success at 12, 24, and 36 months was 74%, 72%, and 65% in nondiabetics and 69%, 63%, and 54% in diabetics, respectively (p=0.17). The limb salvage rate at 36 months was 88% overall (90% in nondiabetics, 82% among diabetics, p=0.20). The 36-month survival rate was 61% in nondiabetics and 57% in diabetics (p=0.29). Conclusions: In terms of clinical outcome, infrainguinal subintimal angioplasty is almost equally effective in diabetics as in nondiabetics suffering from CLI.

Vascular injury in orthopedic trauma is challenging. The risk to life and limb can be high, and clinical signs initially can be subtle. Recognition and management should be a critical skill for every orthopedic surgeon. There are 5 types of vascular injury: intimal injury (flaps, disruptions, or subintimal/intramural hematomas), complete wall defects with pseudoaneurysms or hemorrhage, complete transections with hemorrhage or occlusion, arteriovenous fistulas, and spasm. Intimal defects and subintimal hematomas with possible secondary occlusion are most commonly associated with blunt trauma, whereas wall defects, complete transections, and arteriovenous fistulas usually occur with penetrating trauma. Spasm can occur after either blunt or penetrating trauma to an extremity and is more common in young patients. Clinical presentation of vascular injury may not be straightforward. Physical examination can be misleading or initially unimpressive; a normal pulse examination may be present in 5% to 15% of patients with vascular injury. Detection and treatment of vascular injuries should take place within the context of the overall resuscitation of the patient according to the established principles of the Advanced Trauma Life Support (ATLS) protocols. Advances in the field, made mostly during times of war, have made limb salvage the rule rather than the exception. Teamwork, familiarity with the often subtle signs of vascular injuries, a high index of suspicion, effective communication, appropriate use of imaging modalities, sound knowledge of relevant technique, and sequence of surgical repairs are among the essential factors that will lead to a successful outcome. This article provides a comprehensive literature review on a subject that generates significant controversy and confusion among clinicians involved in the care of trauma patients.
