Possibility of venoarterial extracorporeal membranous oxygenator being a bridging therapy for hemodynamic deterioration of pulmonary tumor thrombotic microangiopathy prior to initiating chemotherapy: A case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
rationalePulmonary tumor thrombotic microangiopathy (PTTM) is a rare but lethal complication of carcinoma, defined as non-occlusive pulmonary tumor embolism complicated by fibrocellular intimal proliferation of the small pulmonary arteries, with eventual occlusion of the pulmonary arteries. Hemodynamic deterioration caused by this condition leads to high mortality. PATIENT CONCERNS: A 46-year-old woman who had undergone radiation therapy for anaplastic oligoastrocytoma and who was taking temozolomide presented with cough and palpitations. DIAGNOSES: A 12-lead electrocardiogram showed sinus tachycardia and SIQIII TIII, with negative T in V1-3. Ultrasound cardiography showed a distended right ventricle. Enhanced chest computed tomography showed no significant thrombus in the major pulmonary artery. The patient's condition deteriorated the next morning, with her blood pressure decreasing to 40 mmHg and her SpO2 unmeasurable. She suffered cardiac arrest.
interventionsWe initiated venoarterial extracorporeal membranous oxygenation (VA-ECMO) and her blood pressure increased to 80 mmHg. Her hemodynamic status stabilized and she was weaned off VA-ECMO on intensive care unit (ICU) day 3. OUTCOMES: Gastroesophageal endoscopy on ICU day 4 revealed gastric cancer (Borrman type IV), and she arrested again and died on ICU day 5. Autopsy confirmed gastric cancer and PTTM. LESSONS: VA-ECMO rapidly stabilized the hemodynamic status of this patient with PTTM, and may thus be a possible bridging therapy for deterioration of PTTM prior to initiating imatinib.
