For 30 years, CO(2) gas has been used as a safe alternative to iodinated contrast agents for angiography in patients with renal insufficiency or allergy to iodine. CO(2) angiography is well tolerated when performed properly, and serious complications are rare. However, severe complications may occur if the physical properties of CO(2) and the specific pathophysiology of an individual patient are not carefully considered. The present report describes a case in which diffuse livedo reticularis, bowel ischemia, and renal insufficiency developed following CO(2) angiography in a patient with CREST syndrome (calcinosis, Raynaud phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia).

We describe the case of a 60-year-old woman with CREST (calcinosis, Raynaud phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia) associated pulmonary hypertension undergoing transradial coronary angiography. The day after the procedure, the patient complained of severe symptoms and signs of acute hand ischemia. Urgent right upper extremity angiography showed the lack of ulnar palmar arch and a severe narrowed radial artery with endoluminal filling defect. The patient was successfully treated with manual thromboaspiration leading to a complete flow restoration and symptom relief. This case shows that radial occlusion, one of the most common and usually asymptomatic complications following transradial cardiac catheterization, may cause severe hand ischemia in patients with small-vessel inflammatory disease.

Red face is not a rare finding in patients with connective tissue disorders. The malar eruption is the most frequent cutaneous manifestation of systemic lupus erythematosus (LE). This condition is more apparent among fair-skinned individuals, and it usually appears after sun exposure. A very important clinical sign is that nasolabial folds remain free of any erythematous or other changes. With subacute cutaneous LE, sun exposure can provoke a red face that resembles the malar eruption of systemic LE. The typical clinical findings of chronic cutaneous LE are the discoid lesions. There is a clinical form of chronic cutaneous LE called erythema perstans faciei. This form is purely erythematous, and it usually appears on the face. Other rare "red face" forms of chronic cutaneous LE are LE tumidus and LE telangiectaticus. Red face is not typical of systemic sclerosis, but facial telangiectasias are frequent, especially with CREST (calcinosis, Raynaud phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia) syndrome. The differential diagnoses of other red face manifestations are easy due to the additional findings. Telangiectasias are accompanied by calcinosis, sclerodactyly, digital ischemia, and Raynaud disease. Many studies mention telangiectasias as markers of the severity of the systemic sclerosis, the disease duration, any pulmonary arterial hypertension, and any esophageal involvement. Purple- or violet-colored upper eyelids are the hallmark and one of the first clinical signs that is helpful for the diagnosis of dermatomyositis. This violaceous to dusky erythema can extend over the whole face and the upper aspects of the trunk. Erythematous changes on the face that are different from those of the heliotrope sign which occurs with dermatomyositis may be observed in both sun-exposed skin and non-sun-exposed skin. Malar and facial erythema, linear extensor erythema, V-sign or shawl sign, and other photodistributed eruptions can also appear.

Systemic sclerosis is a rare autoimmune disorder with a wide spectrum of clinical manifestations and a multitude of autoantibodies that are associated with it. In the past several years, advances in serologic testing have led to research indicating important prognostic and phenotypic associations with certain subsets of autoantibodies. In particular, anti-RNA polymerase III (anti-RNAP III) has been associated with diffuse cutaneous disease, scleroderma renal crisis, a temporal relationship with malignancy, myositis, synovitis, joint contractures, and gastric antral vascular ectasia. However, anti-RNAP III has not been associated with systemic sclerosis sine scleroderma. We describe a patient with an atypical presentation of anti-RNAP III positive systemic sclerosis sine scleroderma who presented without the typical features of anti-RNAP III disease. Instead, she presented with critical digital ischemia, pulmonary arterial hypertension, gastroesophageal reflux disease, interstitial lung disease, and no clinically detectable sclerodactyly.
