Abstract

Penelitian ini merupakan penelitian deskriptif dengan menggunakan metode kualitatif untuk mendeskripsikan berpikir kritis siswa ditinjau dari kemandirian belajar ketika menyelesaikan soal matematika bilangan bulat. Subyek penelitian ini adalah siswa SMP Masehi 1 PSAK VII A yang berjumlah 32 orang. Metode purposive sampling digunakan untuk memilih 1 orang siswa yang mempunyai kemandirian belajar tinggi, 1 orang siswa yang mempunyai kemandirian belajar sedang, dan 1 orang siswa yang mempunyai kemandirian belajar rendah. Teknik data yang digunakan dalam penelitian ini adalah angket, tes tertulis, wawancara dengan dokumen pelengkap. Teknik analisis data yang digunakan dalam penelitian ini adalah reduksi data, penyajian data dan penarikan kesimpulan/validasi. Teknik pemeriksaan keabsahan data menggunakan triangulasi teknik. Hasil penelitian ini sebagai berikut: (1) siswa dengan kemandirian belajar tinggi menghasilkan enam indikator berpikir kritis yaitu focus, reason, inference, situation, clarity, overview. (2) siswa dengan kemandirian belajar sedang menunjukkan empat indikator berpikir kritis yaitu focus, reason, inference, situation. (3) siswa dengan kemandirian belajar rendah hanya menunjukkan satu indikator berpikir kritis yaitu focus.

Abstract

Background: This case report details the management of atypical chronic deep vein thrombosis (DVT) in a 24-year-old male. The treatment of DVT is complex and case-dependent; however, most individuals are managed with oral anticoagulation therapy, while complex cases can be treated with advanced interventions. Only a few publications discuss about endovascular procedure of chronic DVT.  This report discusses a singular case of an atypical or complex DVT undergoing a thrombectomy using an Indigo Penumbra system. Case illustration: A 24-year-old male was admitted to the hospital with bilateral leg swollen for 8 years ago. His history was unremarkable, and he was diagnosed with bilateral lower extremities deep vein thrombosis and was routinely administered anticoagulants. Laboratory results showed a significant increase in d-dimer levels. Venography confirmed bilateral deep vein thrombosis in the femoral vein system. He then underwent percutaneous mechanical thrombectomy with the Indigo Penumbra system. Small fragments of white thrombus were collected from the system container. He was discharged 1 day post-operatively and scheduled for further workup. Conclusion: This case report elaborates on a patient with an atypical chronic white thrombus DVT who underwent a thrombectomy after imaging showed extensive thrombotic disease in the right lower extremity. Despite the few publications, percutaneous mechanical thrombectomy using the Indigo Penumbra System showed promising results in chronic DVT.
